实轴 [
shí zhóu]
[数] real axis
- 当时,这些个极点在负实轴上,在的两边,瞬态响应为两个不同时间常数指数衰减曲线之合。
For , these poles are on the negative real axis, on both sides of , the transient is a sum of two decaying exponentials, each with its own time constant. - 本文运用实轴积分法数值模拟了套管井不同地层、不同衰减条件下三种典型胶结状况的声波测井响应;
By using real axis integration method, the response se of acoustic logging are calculated with different wave velocity and attenuations of formation; - 如果实轴的一部分位于两个开环极点(或者开环零点)之间且属于轨迹,则在其间必有分离点(或者会合点)。
If the part of the real axis between two o. l. poles (o. l. zeros) belongs to the loci, there must be a point of breakaway form, or arrival at, the real axis.
