Simulating and surveying of parallel plate static electric field
1. ** Experiment Purpose ** - Learn to use simulation methods to measure the parallel plate static field, a physical quantity that is not easy to measure directly. - Deepen the understanding of the properties of the parallel plate static electric field (electric field strength and potential) and the concept. 2. ** Experiment Principle ** - It was difficult to directly measure the static field of parallel plates. For example, when the shape of the charged body was complex, the distribution of the static field around it was difficult to calculate theoretically, and the field distribution would be distorted when the instrument probe was placed in the static field. Therefore, the essence of the simulation method was to use a physical state or process (stable current field) that was easy to implement and easy to measure to replace the parallel plate static field that was difficult to implement and inconvenient to measure. The static field of parallel plates was simulated by a steady current field generated by a direct current passing through a poor conductor. In this experiment, a parallel plate static field can be simulated by a transformer. By adjusting the voltage on the transformer, the electric field between the two plates of the transformer can have the same potential distribution as the parallel plate static field. Then, by measuring the electric field strength between the two polar plates of the transformer, the electric field strength of the parallel plate static field was calculated. 3. ** Experimental steps (for reference only)** - Setting up the experimental equipment: - Prepare a parallel plate transformer (for example, the metal plate size is 5cm x 5cm, and the distance between the two plates is 2mm). - Connecting the condensers to the power supply and equipping a voltage meter to measure the power supply voltage. - Measuring related physical quantities: - Using an electric field strength meter to measure the electric field strength between the two polar plates of the transformer, according to the previously established simulation relationship (the electric field between the two polar plates of the transformer has the same potential distribution as the parallel plate static field), the information related to the electric field strength of the parallel plate static field can be obtained. At the same time, the properties of the parallel plate static field could be further studied by changing the relevant parameters of the transformer (such as the plate spacing, the applied voltage, etc.).

The epidemic affects the surveying and surveying industry
The epidemic had a multi-directional impact on the surveying and surveying industry. In China, cities were closed during the epidemic, and the surveying and surveying industry, like most other industries, delayed the return to production after the holiday. By February 2020, after the epidemic eased, the surveying and surveying industry could operate normally. From the perspective of the impact on enterprises, the number of projects started by surveying and surveying enterprises had decreased significantly, and the output value had generally declined to varying degrees, which was then transmitted to employee income, daily operations of enterprises, technological innovation, and so on. Most surveying and surveying enterprises stopped work for 1 - 3 months, the number of market projects decreased significantly, the income of employees decreased, and the scientific and technological innovation activities of enterprises were affected by insufficient funds in the short term. In terms of personnel, more than 80% of enterprises reported that it was difficult to recruit talents. On the one hand, the performance of enterprises was affected by the change in employment treatment, which reduced the attraction to talents. On the other hand, the college resumed classes and personnel travel was blocked, so the online recruitment effect was not as good as offline. Some fresh graduates adjusted their plans to continue studying for degrees. However, the personnel of surveying and surveying enterprises were relatively stable and maintained a certain ability to absorb employment. Some enterprises recruited new employees during the epidemic period, and there were new employees. At the same time, surveying and surveying companies put forward relevant demands and suggestions in many aspects such as surveying and surveying qualifications, registered surveying and surveying system, and surveying and surveying results. On the international level, if an enterprise has international business and is affected by foreign epidemic prevention and control measures, the business development in Europe, America, Africa and other places is limited. For example, all work during the period of South Africa's fief requires permission, and the high employment rate is not conducive to the development of work. The enterprise's work plan may be delayed or cancelled. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
