As an entry-level DSLR model, the Nikon D3200 had the following lens combinations according to different needs: 1. ** Basic entry-level model **: You can choose the Nikon AF-S 18 - 105mm F3.5 - 5.6G ED VR. The price is about 1649 yuan. Its advantage was that it was cheap, light, and had a wide range of focal lengths, but its disadvantage was that the plastic body was less durable than an all-metal lens. 2. The Nikon 18 - 200mm f/3.5 - 5.6Ge DV RII was an option, priced at about 5999 yuan. The advantage of this lens was that it covered a wide angle of 18 to a telephoto of 200. The lens was short and easy to carry and use. The disadvantage was that the zooming was too large, which made the image quality poor, especially in the telephoto segment above 100. 3. ** Travelling model **: Can use a combination of fixed-focus lens and zoom lens, namely Nikon AF-S DV Nikkor 35mm f/1.8G and Nikon AF-S 18 - 105mm F3.5 - 5.6G ED VR. The price is about 1449 yuan + 1649 yuan respectively. This combination was ideal for shooting portraits in the environment. The 35mm f/1.8G lens had a 1.8 aperture, which was also good for indoor documentary. The disadvantage was that the image distortion effect was not outstanding. 4. ** For beginners to practice DSLR operation **: If you mainly want to meet the needs of landscape photography, portrait photography, or even macro photography, you can also choose 18 - 55 lens sets first, which is cost-effective. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

The distribution of soil microorganisms was not random, but was affected by environmental slopes. Studying the geographical distribution and ecological mechanism of soil microorganisms is of great significance to understand the ecological process of soil ecosystem. Soil microorganisms participate in ecological processes such as soil formation and nutrient circulation, and play an important role in the stability and health of the ecosystem. They participate in almost all biochemical changes in the soil under different geographical distribution. For example, heterotroph microorganisms decompose organic matter, autotroph microorganisms transform the existing state of mineral nutrients; microorganisms are the main members of the synthesis of soil humus, thus affecting soil fertility and soil structure; Photosynthetic microorganisms can increase the content of organic carbon in some environments, especially in environments without vegetation. Algal is the forerunner of soil formation or restoration. The distribution of soil microorganisms under different geographical distribution also affected the growth and development of crops. Most soil microorganisms were beneficial to the growth and development of crops. Of course, there were also pathogenic microorganisms. In different geographical environments, the distribution of soil microorganisms was different, and the role they played was also different. This had a broad and important significance for the entire ecosystem. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

The following is the training content related to the reproduction of microorganisms in water and water quality treatment: * * I. Requirements for the reproduction of microorganisms ** 1. * * Nutrient Source ** - The reproduction of microorganisms required sufficient nutrients such as carbon, nitrogen, and phosphorus. These nutrients were the basis for microorganisms to construct their own cell materials and carry out their metabolism activities. For example, organic matter such as vitamins and protein in sewage could provide nutrients such as carbon and nitrogen sources for microorganisms. 2. * * oxygen content ** - Aerobic microorganisms required sufficient dissolved oxygen. Generally speaking, dissolved oxygen should be maintained at 3 milligrams per liter, and the minimum should not be lower than 2 milligrams per liter. Moreover, shaking cultivation was usually required to ensure an adequate supply of oxygen. - Anerobic microorganisms needed to grow in an anerobic environment, and the dissolved oxygen was required to be below 0.2 milligrams per liter. - The oxygen requirement of faculty-type microorganisms was between the two. They could survive in an environment with dissolved oxygen ranging from 0.2 to 2.0 milligrams per liter and could be cultivated in a stationary manner. 3. * * pH-value ** - Most microorganisms adapt to a range of 4.5 - 9, but different microorganisms have differences. In the case of an aquatic biological treatment, the appropriate ph can be changed between 6.5 - 8.5, and in the case of an aquatic biological treatment, the ph should be between 6.7 - 7.4. For some microorganisms, it was more suitable to control the range of the ph between 7.0 and 9.2. If the pH-value deviated from the appropriate range, it would affect the life activities of microorganisms. For example, when the pH-value was lower than 6.5, fungi might begin to compete with bacteria. When the pH-value reached 4.5, fungi would have a complete advantage in the biochemical pool, which would seriously affect the settling results of the sludge. When the pH-value exceeded 9, the metabolism speed of microorganisms would be hindered. 4. * * Atmospheric temperature ** - In the biological treatment of waste water, the most suitable temperature range for microorganisms is generally 16 - 30 ° C, and the highest temperature is 37 - 43 ° C. When the temperature is lower than 10 ° C, the microorganisms will no longer grow. Within the appropriate temperature range, the metabolism rate of microorganisms would increase correspondingly for every 10 ° C increase in temperature, and the removal rate of chemical oxygen demand (COD-based oxygen demand) would also increase by about 10%. On the contrary, the removal rate of COD-based oxygen demand would decrease by 10% for every 10 ° C decrease in temperature. For some microorganisms, controlling the temperature to 30 - 40 ° C was more conducive to reproduction. 5. * * Light (Part of Microorganisms)** - Microorganisms such as green algae needed to photosynthesize, and light was a necessary condition for their reproduction. * * II. The role of microorganisms in water treatment and related principles ** 1. * * The advantages and role of microorganisms in sewage treatment ** - Microorganisms mainly existed as the decomposing agents in the biosphere, and their greatest value lay in their decomposing function. There were many microorganisms that could degrade polluting substances in natural water and soil. This was also the reason why water and soil had a certain self-purification ability. In sewage treatment, an ecosystem suitable for the growth of microorganisms was artificially created. Energy transfer and material circulation were achieved through the synergy between microorganisms. Microorganisms have the advantages of strong reproductive ability, small shape, large surface area, fast and strong metabolism, wide variety of metabolism products (containing more types and quantities of degrading membranes), large population and wide distribution, strong environmental adaptability (easy to mutate after being affected by environmental factors, able to form a rapid and effective material exchange with the surrounding environment), etc. These advantages make it effective in degrading the pollution in the water. 2. * * Methods and Principles of Microbiological Waste Water Treatment ** - * * Aerobic microorganisms treatment method **: Aerobic microorganisms have strong decomposition and reproduction characteristics, which can quickly break down the complex molecular substances in the water into relatively simple small molecular substances, thus changing the water quality. Under the presence of oxygen, the autotrophs of the nitrating bacteria would vaporize the nitrogen nitrogen (NH-N) to the nitrogen nitrogen of the nitrates (NO-N). This process required the participation of oxygen and had certain requirements for environmental conditions (such as ph, temperature, dissolved oxygen concentration, etc.). - [** Biochemical Treatment Method **: This treatment method is mainly used in high-concentration organic waste water and underwater sludge.] In an airtight environment, the bacteria would break down the organic matter in the waste water into carbon dioxide, methane, and other substances. Under the anoxic-deficient or anoxide-deficient conditions, the detoxifying bacteria used organic matter as an electron donor to reduce the nitrogen of nitrates and nitrates into nitrogen (N <2>), thereby achieving the removal of nitrogen. - * * Microbiological facultive treatment method **: When both good and bad oxygen coexist in the same treatment process, it is facultive treatment. It was found that sometimes the co-existence of both oxygen and oxygen could make the treatment effect better. 3. * * The application of microorganisms in water treatment ** - At present, the market mainly combined a variety of microorganisms with different degrading functions with active biological membranes and nutrient salt, and after industrial production and expansion, they produced live bacteria preparations, namely, microorganisms. Microbiological agents had the advantages of strong uniqueness, high survival rate, fast adaptation to the environment, no secondary pollution, and low cost. They were now widely used in agriculture, petrification, printing and dyeing, food processing, medicine, and environmental protection, especially in water pollution control, soil restoration, and solid waste recycling. 4. * * Microorganisms in the Electro-Biochemical Waste Water Nourishment and Denitration Biochemical System Treatment Technology (example of new technology)** - In the biochemical sewage treatment technology of the biochemical system, by applying a weak electric current, it could stimulate the metabolism activity of microorganisms and improve the decomposition efficiency of microorganisms. The effect of the electric field helped to promote the transfer and spread of substances, making it easier for microorganisms to obtain nutrients, and at the same time, it was also conducive to the discharge of metabolism products. The electric field conditions could selectively promote the growth and reproduction of certain microorganisms with specific functions, optimized the structure of the microorganisms, improved the treatment effect, and helped the transfer of electrons between microorganisms and between microorganisms and microorganisms, accelerating biochemical reactions. * * III. Relationship between microorganisms and water quality indicators ** 1. * * Biochemical oxygen demand (Biochemical oxygen demand)** - The organic matter in the sewage consumed oxygen in both the chemical and biological processes. The more organic matter in the sewage, the more oxygen was consumed. The amount of oxygen consumed by the chemical agent for the sewage was called the chemical oxygen demand, and the amount of oxygen consumed by the microorganisms in the sewage was called the biochemical oxygen demand. The difference between the two could indicate the organic matter in the sewage that could not be biodegraded. In the sewage treatment process, because there were many detection instruments for the determination of oxygen demand and oxygen demand, the detection method was simple, and the test results could be obtained in a short period of time, so they were widely used in water quality detection and analysis. They became an important indicator for water quality monitoring and an important basis for environmental monitoring of water bodies. 2. * * Microorganism and Water Treatment Effect Assessment ** - For example, in the water treatment process of the open circulating water system, the purpose of water treatment was to always control the microorganisms within a certain range (the total number of bacteria was less than 105 CPU/ml). Through the control and detection of the number of microorganisms, the effect of water treatment could be evaluated. If the number of microorganisms exceeded this range, it might cause algae and microorganisms to grow and spread, flow into the terminal equipment, block the equipment, and affect the heat exchange effect. If it was serious, it would cause the heat exchange to be delayed, causing the equipment to be shut down and the risk of stopping production. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

The complex phenomena in biology covered many aspects. From the perspective of the relationship between biological individuals, there were individual relationships, population relationships, and ecosphere relationships. There were also invisible energy flow and information flow relationships. This entire system constituted a highly complex network system. For example, in terms of biological molecules, many important biological molecules had complex heterostructures. DNA molecules not only had a double spiral structure, but also formed complex " knots " under certain circumstances. About 1% of the protein also had this complex knot structure. The oscillation and bistability behavior in biological systems were also complex non-linear phenomena. The oscillation behavior was commonly seen in various biological rhythms, from the metabolism oscillation of cells to the periodic rhythm of biological clocks. There were many complicated situations, such as external periodic stimulation that could lead to the co-existence of multiple oscillation modes. In addition, the variety of organisms was also a complex phenomenon. There were many species of organisms on Earth, and they needed to be classified and studied. This also reflected the complexity of biological phenomena. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
