In circuit theory, the feedback signal was a signal that was taken out of part or all of the output signal of the basic amplifier and then sent back to the input of the amplifier through a certain method. When the feedback signal is mixed with the input signal, it will form a new net input signal, which will affect the input and output characteristics of the circuit. According to its effect on the net input signal, feedback can be divided into positive feedback and negative feedback. Positive feedback would increase the net input of the amplifier circuit, which might cause the circuit to be overly excited, causing oscillation or distortion, but it had special uses in certain situations (such as making electronic instruments). Negative feedback reduced the net input of the amplifier circuit, which could correct the deviation of the output like a strict coach, so that the circuit remained stable and linear. It was widely used in electronic products (such as smart phones, precision medical equipment, etc.). Negative feedback can also be divided into voltage feedback, current feedback, or a mixture of the two according to the different sample methods. The voltage feedback could adjust the gain of the amplifier by controlling the size of the feedback resistance, and the current feedback could improve the response speed of the circuit in high-speed operation and high-frequency amplifier. In terms of circuit components, a feedback circuit usually consists of a feedback network, an amplifier, and a feedback source. The feedback coefficient is the ratio of the feedback signal to the output signal. The closed-loop gain (the actual gain after considering the feedback) can be calculated by the open-loop gain (the gain without feedback) and the feedback coefficient.

From the reference materials, there were many pieces of information about Tu Jinshi, but they were scattered. There was the engraving work "Tu" from the Jinshi Great Dictionary1, the string-patterned Slaughtering Golden Stone Box from the Northern Song Dynasty, and the mysterious sentence "Yin Chen is evil, inviting the slaughter of Jinshi". There was also a painter named Jin Shi, whose experience was mainly in painting and portrait drawing, but it was not directly related to the expression "Tu Jin Shi". Due to the lack of clear integration logic in the reference materials, it was difficult to determine whether "Tu Jinshi" was an exact concept or just a coincidence that some of the same expressions were used in different things. The novel,"The Morality of the Past", is equally exciting. Everyone is welcome to click and read it!
There were many differences between Taoism and Buddhism. - Origins: Taoism originated from Chinese culture and was a local religion; Nepal originated from India and then spread to China and was a foreign religion. - ** Cultivation purpose **: Taoism focused on cultivating this life, pursuing to live without regrets. Its goal was to become immortal, ascend in the daytime, and sanctify the body. Its goal was to pursue immortality and immortality, striving to obtain eternal life in harmony with the universe. Buddhism focused on the afterlife and talked about karma. They believed that today's situation was the karma of the past life. The main goal of Buddhism was to transcend suffering, pursue Nirvana, and achieve eternal release. - ** Understanding of the universe **: Taoism believes that the universe is made up of five substances: metal, wood, water, fire, and earth, and these substances really exist; Buddhism believes that the universe is made up of four substances: earth, water, fire, and wind. These substances gather by karma and disperse when the karma is exhausted, so the four are empty. - ** Cultivation focus **: Taoism pays attention to the dual cultivation of life and nature. They believe that life is divided into three parts and nature is divided into seven parts. They believe that nature is the foundation of life and life is the end of nature. Buddhism only cultivates the mind and believes that the human body is a stinky skin. They don't care about the body. They aim to clarify the mind and see nature, directly pointing to the Buddha's heart. - ** Internal Unity of Religion **: Although Taoism originated from unification, it was difficult to unify many different sects; Buddhism had a unified Dharma name, such as Amitabha. - ** Concept of life and death **: Taoism placed the hope of cultivation in this life, which was more positive; Buddhism placed the results and hopes of cultivation in the afterlife. In the view of life and death, life and death were a kind of suffering, which should be transcended. It was relatively negative, and emphasized the realm of freedom and transcendence of life and death, pursuing the suffering of all living beings. - ** Name of residence **: In Taoism, the palace, temple, mansion, hall and altar were used by Taoist priests and nuns to worship the gods. The god of Qian was called Tianzun, God, Emperor, Emperor and True Lord; the god of Kun was called Yuanjun, Mother, Empress, Concubine and Madam; the god of protection was called Lingguan, Tianjun or Marshal; the god of plague or the god of protection was called Dawang, Qiansui or Wangye; Buddhism did not have such a specific name system for residence. - Cultivation Method: Daoists can pursue peace of mind and longevity through alchemy, meditation, and health preservation. Buddhists emphasize meditation and mindfulness, and cultivate through the three methods of concentration, wisdom, and precepts. - ** Belief System Focus **: Taoism pays more attention to the harmony between man and nature, man and society, emphasizing that "Tao" is the root of everything, and pursuing to find one's own place in nature; Buddhism emphasizes the concept of release and Nirvana, pursuing release and transcendence. Its belief system puts the value of life on the other side and the future to realize.

The following is a novel about how cat tears come about: The Secret of Cat Tears In a quiet town, there was an animal researcher named Ellie. She had a strong interest in cats, especially their mysterious tears. Allie knew that cats 'tears were related to their physiological structure. Cats had tear glands in their eyes, which were the source of tears. The lacrimal gland was like a small factory, continuously producing tears. Tears contained water, salt, and some special protein. One day, Allie found a kitten in her lab with tears in her eyes. She began to examine it carefully. She realized that the kitten's eyes had accidentally gotten into a tiny strand of fur. The fur was like a naughty little devil, stimulating the kitten's eyes. This stimulation made the lacrimal glands abnormally active, like a machine that was working step by step suddenly accelerating. After the lacrimal glands were stimulated, they secreted tears at an accelerated rate in an attempt to wash away this annoying foreign object, so tears kept flowing out. Ellie also found that sometimes the cat's tear glands would be blocked. It was like a river being blocked by sand. Tears could not be discharged through the tear passages normally, so they accumulated in the eyes. As a result, her eyes were filled with tears, looking like tears of grievance. In this small town, there were many cats who cried because of their diet. There was a cat named Tom who liked to steal his master's bacon. Its master would often give it some leftovers, which were too salty. When excessive salt entered the body, it affected the balance of the cat's internal environment, which in turn affected the health of the eyes. Under such a bad physical environment, the lacrimal glands would also have a secretion disorder, and tears would flow out unconsciously. In addition, Allie also noticed that although cats did not shed emotional tears like humans, under some special circumstances, their physical reactions would also cause them to show similar sadness. There was a female cat who had just lost her cub. The female cat's body was in a state of stress. In this state, the body's hormone levels changed, indirectly affecting the secretion of the lacrimal glands, causing tears to appear in the eyes. Although this was not because emotions triggered tears like humans, it was also a reaction of the body to such a painful situation. After a long period of research, Allie finally understood the various sources of cat tears. She shared these research results with every cat owner in the town so that everyone could take better care of their cats. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
One could usually tell that a person was an actor from the following aspects: 1. ** Work presentation **: If a person appears in movies, TV series, plays, web dramas, and other film and television works and takes on the role of a certain character, then he is likely to be an actor. For example, Yu Shi starred in many movies such as "The First Apotheosis: The Wind and Cloud of Zhaoge" and was recognized as an actor by the audience through his performance in these works. Song Jia played a role in "When the Mountain Flowers are in Bloom," which was also the embodiment of her role as an actor. 2. ** Occupation-related activities **: participate in activities related to performances, such as film festivals, TV drama awards, film and television conferences, etc. On these occasions, actors would promote their works, accept awards, or interact with their peers. 3. ** Acting-related ability display **: Possess acting ability, such as being able to interpret characters with different personalities, identities, and backgrounds. Through expressions, body language, lines, etc., express the emotions and thoughts of the characters in different situations. It was an important aspect of an actor's acting skills. 4. ** Industry recognition and honor **: Accomplishing awards related to film and television, such as the Hundred Flowers Award for the Popular Film (Yu Shi won the Hundred Flowers Award for Best Newcomer Actor), awards from the Media Attention Unit of the Movie Channel, etc. These awards are recognition of an actor's performance and also indicate his identity as an actor. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
