Article "Essence of System Science" Reading Question

Systems Science is a new comprehensive scientific category formed by systematic thought as the center and the content of multiple disciplines. The emergence of systematic science not only means the addition of another major category to the modern scientific system, but also is related to a scientific revolution.

Don't show your emotions casually.2 Don't tell everyone about your difficulties and encounters. 3 Before asking for other people's opinions, think about it yourself, but don't talk about it first. 4 Don't talk about your dissatisfaction at every opportunity. 5 Important decisions should be discussed by others as much as possible, and it is better to release them every other day.

points) High school Chinese reading comprehension answer: 1 (4 points) deeply influenced by traditional culture and profound literary skills; quite have the legacy of ancient gentlemen and adhere to traditional morality; advocate clear talk and discussion, often detached from reality; pedantic dogma, do not know how to be flexible.

"In the Digital Age, Our Brains Have Been Changed" Read the title and Answers 1 Read the full text and talk about what changes the digital age has brought to our brain. 1 Changed the way of thinking of human beings. 2 Make our thinking "fragmented" is not enough to exercise patience.

An article to understand the exhaust back pressure, the exhaust system is much more complicated than you think

This That's what we call exhaust backpressure. Simply put, the exhaust back pressure can also be regarded as the exhaust resistance, which comes from the bending and confluence of the exhaust pipe, etc. The greater the exhaust back pressure, the greater the exhaust resistance, and the less easy it is to discharge the exhaust gas;The smaller the exhaust back pressure, the smaller the exhaust resistance and the smoother the exhaust.

The exhaust back pressure will make the exhaust not smooth, which can reduce the loss of pump air. Improving the low-torque exhaust back pressure of the engine is due to the internal resistance of the exhaust pipe. The exhaust pipe of the family car exhaust pipe has exhaust back pressure. The family car will not be used through exhaust. Each car engine has an intake valve and an exhaust valve. When the intake valve opens.

Exhaust back pressure: As the name implies, it is the pressure behind the exhaust pipe. The exhaust back pressure has an important impact on the dynamics, economy and emission performance of the engine. Usually, the increase in back pressure will lead to a decrease in engine fuel combustion efficiency, a decrease in economy, a decrease in power, and a decrease in emissions.

The diameter of the exhaust pipe can be determined according to the exhaust gas displacement and the selected flow rate. Finally, it is necessary to determine whether the resistance of the exhaust system exceeds the back pressure range of the engine.The pipeline drag calculation is very mature, and there are many computer programs that can carry out drag calculation. The back pressure calculation method requires relevant books and professional knowledge.

I think the semi-straight tube and the semi-back pressure tube are the same, but the outlet diameter is larger than that of the semi-back pressure tube: the starting torque is lower than that of the semi-back pressure tube, but the torque is greater at medium and high speeds. Variable exhaust pipe The exhaust is regulated by the valve to keep the sound and performance in the best state. Common problems: drainage, car exhaust pipe dripping is a good phenomenon.

The working principle of the back pressure valve is to realize the action through the elastic force of the built-in spring: when the system pressure is less than the set pressure, the diaphragm blocks the pipeline under the action of spring elasticity; when the system pressure is greater than the set pressure, the diaphragm compresses the spring, the pipeline is connected, and the liquid passes through the back pressure valve.

There is a shortage of books. Please recommend good urban novels or systematic articles.
