... Видимо, самым популярным предположением о состоянии газа или газообразного вещества, является модель идеального газа. (иногда добавляют одноатомного газа, но в нашем рассмотрении это несущественно). ... Уравнение идеального газа в отношении его давления записывается обычно в виде . ... В астрофизических приложениях уравнение идельного газа играет значительно большую роль, если его использовать при вычислениях давления отдельных компонент, составляющих рассматриваемый газ. ...

Next: The Stopping Radius in Up: ``Ecology'' of Magnetic Rotators Previous: The Environment of the . Now we consider qualitatively the effect of the electromagnetic field of a magnetic rotator on the accreting plasma. ... What is important is that both relativistic particles and magnetic dipole radiation will transfer their momentum and hence exert pressure on the accreting plasma. ... 2) The pressure of the accreting plasma is high enough to permit the plasma to enter the light cylinder . ...

... The initial indications are that the safing was a result of a pressure gauge in the Aft Shroud measuring an abnormal pressure. This gauge was originally installed to check for leaks of neon from the cooling system, but is sensitive to anything else that might introduce gas into the aft shroud. At about the same time, there was an excessive current measured in the power system, and the ACS power appeared to be shut off, likely by a blown fuse. ...
