1, the following is the role of the fairing: Protect the satellite: The fairing relies on small engines inserted between the bullets to throw out. The fairing is unlocked when it begins to move to allow the bullet head to tilt outwards as the missile accelerates. So it protects the satellite from aerodynamic heating. Facilitate separation: Unlocking the separation system ensures the smooth separation of the satellite fairing.
2, protect the satellite from the effect of air power; To protect the satellite from exposureThe action of dynamic heating; Unlocking separation system ensures smooth separation of satellite fairing; When the launch vehicle is in the pre-launch state, the temperature and humidity in the fairing can be adjusted to ensure that the satellite is not affected by low temperature and environment. The satellite in the shield is protected from all kinds of smog. It has a certain function similar to the escape tower.
3, before the rocket is launched, the fairing protects the spacecraft on the ground to ensure the requirements of temperature, humidity and cleanliness of the spacecraft. When a rocket takes off through the atmosphere, the fairing protects the spacecraft from aerodynamic and aerodynamic heat damage. Once the launch vehicle is out of the atmosphere, the fairing willSplit in half along the length of the arrow body and cast aside, fulfilling its mission. 4, the carrier rocket fairing has the following two roles: one is to protect the spacecraft in the fairing, to provide a good environment for the spacecraft, to withstand various influencing factors caused by high-speed airflow, including aerodynamic, aerodynamic heat, noise and so on; Second, when escape is implemented in emergency, the fairing, as a force transfer structure, bears the load action during escape flight.
5, First of all, the fairing can effectively protect the satellite. During satellite launch, the fairing ensures that the satellite stays high through its unique design and small engine boostp>

Although the hook does not need to punch holes to damage the wall, it is unstable, so it is not recommended to buy. The appearance level is very high, and it looks very textured, but he has a fatal disadvantage that it is easy to rust. The handle is wooden, the basket body is iron, and it is easy to rust and mold if it is not dried in time with water, so I wanted to buy it as a vegetable basket, but because of a lot of waterFruits and vegetables have moisture, and if you are not careful, you will rust and not clean.

1. Origin of the universe: Cosmological observations indicate that the universe is expanding. Through observations of the microwave background radiation and the large-scale structure of the universe, the history of the universe can be traced back to the very early Big Bang. Basic physics as we know it, like generalized relativeNeither theory nor the Standard Model of particle physics applies there. To understand the origin of the universe, we need to understand the basic physics of the Big Bang.
2, if you want to put a quantum physicist or a philosopher of science in the position, just ask the "measurement problem". Simply put, a particle can only be in a particular position if there is an observer measuring it; This is the problem of "measuring" or "observing". This means that the particle is everywhere, until people decide to observe it in their own space-time. In other words, the very act of observing influences or creates reality.
3. This concept of complementarity appliesIn the whole of physics, even beyond the physics field and become a universal philosophical principle. What is the uncertainty principle? Try to explain its physical meaning. Uncertainty principle: To measure the position of a microscopic particle, if the uncertainty range is △q, and the momentum of the measurement also has an uncertainty range △p, then there is a relationship: △p·△q ≥ h, which is the so-called uncertainty relationship.
