The Principle and Usage of the Bio-Stimulation Reaction Device
Biostimulation feedback device principle: - Based on the relationship between muscle electrical activity and muscle contraction, weak electrical activity signals (muscle electrical signals) generated by muscle movement controlled by the nervous system were collected from human muscles through an electric pole (surface or needle). - The collected signals would be converted into digital signals, filtered, amplified, and so on. The purpose was to extract effective muscle electrical signals and remove interference signals (such as electrocardiac signals, muscle tremors, etc.), then converted into recognizable light, sound, images, curves, and other signals, and then fed back to the user. - It could also detect the pressure level of the body by detecting the periodic contraction and relaxation of muscles. It could also detect the different vibrations produced by the body during muscle contraction and relaxation to detect the pressure level. Some types of biostimulation feedback devices (such as those used for repairing the Pelvic Floor muscles) used biofeedback technology combined with bioinformation principles and bioengineering technology to give electrical stimulation to different patients with different frequencies and specific safest pulse width. Usage: 1. Prepare the necessary equipment (such as electromyograph, electromyograph, thermometer, breathing monitor, etc., depending on the type of instrument and the use scenario). 2. Connecting the relevant equipment (such as electrograph, electromyograph, thermometer, and respiratory monitor) to the biostimulation feedback device (including connecting the output of these devices to the input of the biostimulation feedback device). 3. He placed the muscle contraction and relaxation detector and began to measure the frequency of muscle contraction and relaxation to detect the body's stress level or achieve other purposes such as rehabilitation training.

The greater the stimulation, the greater the reaction. What is the principle?
The greater the stimulus, the greater the response. This principle involved the relationship between stimulus and response. From a biological point of view, the human body's stimulus feedback mechanism included perception, transmission, processing, and response. When external stimulation acts on the human body's sensory organs (such as the eyes, ears, nose, tongue, skin, etc.), these sensory organs will transmit the stimulation signal into the nerves, and then through the neural mechanism of the nerve center to decode, select, judge, and finally output the nerve to respond to the action. During this process, if the intensity of the stimulation was greater, it might cause a stronger reaction. For example, in terms of perceptual stimulus response, when the stimulus reached a certain threshold (the critical value of the sensation), the receptor received a strong stimulus, which would cause the human body to produce a more obvious physiological and psychological reaction. For example, when one heard a sudden loud noise (a loud stimulus), the human body would have a strong panic reaction, such as a rapid heartbeat, high muscle tension, etc. This was because the perceptual neural network in the brain made corresponding adjustments to this kind of high-intensity stimulus. The same was true for emotional stimulation responses. When people experienced relatively strong emotional stimulation, such as extreme anger, this large emotional stimulation would make the facial muscles tense more, the heart rate faster, and the emotional agitation stronger. This was regulated by the emotional center and the autonomous nervous system. There was a similar phenomenon in the field of consumer behavior. If a brand gave consumers strong enough stimulation (satisfying certain stimulation conditions, such as the length of stimulation, repetition, intensity, simplicity, compound feeling, etc.), it might cause a greater reaction from consumers, such as making consumers have a deeper impression of the brand or prompting them to make consumption decisions. In addition, from the perspective of conditioned reflex in psychology, through repeated conditioned and unconditioned stimulation, if the intensity of the stimulation is greater, the response to the conditioned reflex may be more intense. For example, if a brand is often associated with children's health with high-intensity publicity (greater stimulation), it may make consumers think of children's health more naturally and strongly when they see the brand. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Principle of Allergen Reaction
Allergy reactions are caused by some people being overly sensitive to the substances (allergens) they come into contact with. When a sensitive individual comes into contact with a foreign, harmless substance (an allergy), the immune system will overreact and the body will produce a type of protein specific to the allergy. These IgE-bound to the high-affinity receptor on mast cells and basophils. When the allergy entered the body again and met with these bound molecules, the form of the immune receptor would change from a dimmer to a monolith. This change in form would lead to the exposure of the protein sites of the relevant signaling pathways, which would activate the downstream signaling pathways, causing allergic reactions such as vasodilation and bronchiectomy. In severe cases, it could cause allergic shock. In an allergic reaction, the affected organs or tissues will be infiltrated by a large number of inflammatory cells (especially those that are not activated), and a high concentration of IgE will appear in the serum. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Biuret and protein reaction principle
The principle of the reaction between biuret and protein was that biuret could react with copper sulfuric acid to form a purple substance. This might be caused by the peptidic bond structure in the biuret molecules. The nitrogen atom of the peptidic bond would form a purple complex with Cu2 + ions. Because there was also a peptidic bond structure in the protein, such a reaction would also occur. We called the purple reaction between the compound containing the peptidic bond structure and copper sulfuric acid solution "biuret reaction". In other words, as long as the molecules contained a peptidic bond, this characteristic purple reaction would generally occur. It wasn't that biuret reacted directly with the protein, but the reaction between the peptidic bond in the protein and copper ions. It was the same reaction type as biuret and copper ions. It was a " biuret reaction." When carrying out experiments related to the biuret reaction, biuret reagent A was a strong base, and biuret reagent B was copper sulfuric acid. When using it, add A to the protein solution first, shake it up, and then add B. Strong base and copper sulfuric acid can denature the protein, but this does not affect the purple reaction, because the essence of protein degeneration is that the spatial structure is destroyed, causing it to settle and lose its physiological activity. However, the bond structure and the sequence of the protein chain are generally not destroyed. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Reaction Principle of Acid and Nitrite
The principle of the reaction between the two substances was that the reaction between the two substances would produce NaCl2, H2O, NO, and NO2. The reaction equation was 2NaNO2 + 2HQ = 2NaCl2 + H2O + NO + NO2. This was mainly due to the fact that the nitrogen acid was unstable and would decompose quickly. Moreover, nitrogen acid was a weak acid. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
The selective principle of the ozon reaction is
In the Ozonation reaction, the reaction between the oxygen and the organic matter was selective in many aspects. In the direct fermentation method of waste water treatment, there was a selective reaction between the oxygen molecules and the contamination. For example, it was difficult for the oxygen to catalyze saturated fatty organic matter. Ozonidation could not completely decompose organic matter into CO2 and H2O, and the products after its decomposition were often organic compounds. Moreover, in the direct oxidization, the main thing was to convert the big molecular organic matter into small molecular organic matter. The overall degree of oxidization was not high, and the effect on the reduction of the total organic carbon content was not obvious. At low doses and in a short period of time, it was impossible to completely metalize the impurities due to the selectively generated oxygen. Moreover, the intermediate products generated by the decomposition would prevent the further decomposition of the oxygen. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
The selective principle of the ozon reaction is
Ozonation reaction was selective, and the order of the reaction was as follows: alkene> amine> phenols> polyaromatic> alcohol> carbols> alkyls. When a variety of impurities exist, the reaction rate of oxygen (O3) will be prioritized with the fast reaction rate of the impurities. When the PH is less than 11, it is mainly the molecular oxygen reaction, which has the characteristics of selective oxidization. The main impurities are the wastewaters with high molecular oxygen reaction rate constant, such as alcoholic wastewaters and high-ph wastewaters. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Reaction Principle of Toothpaste and Iodine
The components of the toothpaste were composed of zinc-citrate, sodium-glyconate, and sodium-oh. These components could react with the iodine-like substance in the tincture to form the iodine-like substance. Generally, the iodine-like substance was only slightly pale yellow, so when the tincture was dripped into the toothpaste water and stirred, the color of the tincture would disappear. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

The Light Reaction Principle of Purple Light
The reaction principle of the purple light was as follows: The fluorescent reaction of a purple light lamp was based on the principle of luminescence. When a violet light (a violet flashlight) shone on certain substances, these substances would selectively absorb the violet light emitted by the violet light. The molecules would be stimulated, and they would emit visible light of the same wavelength and different intensity. When the light stopped, the fluorescence disappeared. When the infrared rays hit the fluorescent substance, there were three general situations: part of the infrared rays were reflected; part of the infrared rays were absorbed by the fluorescent substance; and part of the infrared rays were transmitted. The fluorescence occurred due to the absorption of the fluorescent substance. After the fluorescent substance absorbed the infrared rays, the internal energy state of the molecules changed, showing a transition between different energy levels and releasing fluorescence. For the Lighthouse series of purple lamps, the principle of light was to bombard the special fluorescent material inside the lamp with electric arcs after being energized, and then produce purple spectrum light waves. The violet light could be divided into the UUA band (320 - 400 <anno data-annotation-id ="00000100 - 400a-400a-400a-800a-8000000000000"> wave-length </anno>), the UVP band (275 - 320 </anno>), the UVP band (200 - 275 </anno>), and the UVR band (100 - 200 </anno>). Among them, the fluorescent powder in the purple tube could convert the arc energy into long-wave violet radiation in the UVA-band, such as the UVA-band of 340 - 380 run, and the UVA-band of 365 run was more suitable for checking the fine traces of the collection and fluorescent anti-counterfeit work. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Reaxff reaction force field principle
ReaxFF was a molecular force field based on bond level. It is commonly used in molecular dynamics simulations. Goddard and his collaborators at the California Institute of Technology suggested. In its simplest form, as a bridge between chemical quantum and the experiential force field, it used a set of relatively simple functions to describe the relationship between energy and geometry. For example, it used the EFF method to deal with the simple harmonic-wave equation of the condensed matter system. These equations were used to describe the stretching, compression, and bending of bond angles. However, the current reference materials did not have more in-depth information about its principle, so it was impossible to answer further. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
