衰减

It is not clear what causes the lithium to be destroyed.

但是，目前为何锂会衰减的机制还不是很清楚。

In the process of venting and exposure, the compressive component increases rapidly with the admission of room air and then reaches saturation, followed by a logarithmic decrement of the compressive state in the succeeding hours.

真空室放气和样品暴露大气的过程中，首先是压应力迅速上升，达到饱和状态，然后有一个与对数时间呈现线性关系的压应力衰减过程。

So the conclusion that the logarithmic decrement rule fitting for linear systems widely cannot be used in nonlinear unbalanced bearing rotor systems directly, therefore some reference are given to establish the new stability rule for nonlinear unbalanced bearing rotor system.

First, multi-conductor transmission lines are cut into pieces, every piece is modeled by a GTC cell. ABCD matrix of transmission lines is obtained via ABCD matrix of GTC cell. Maclaurin series of the matrix are obtained with great ease.

将非均匀、耦合、有耗多导体传输线分段，每段由一频域的GTC模拟，根据GTC的ABCD矩阵得出多导体的ABCD矩阵，接着将其麦克劳林展开式嵌入网络的修改节点方程并求得电路的频域冲击响应，利用指数衰减多项式求得时域冲击响应。

First, multi-conductor transmission lines are cut into pieces, every piece is modeled by a GTC cell. ABCD matrix of transmission lines is obtained via ABCD matrix of GTC cell. Maclaurin series of the matrix are obtained with great ease. The series are entered into the overall circuit MNA equations as a stamp. Then impulse response in S domain is gained.
