变星是一种亮度增加的交替降低。对于一个这样的明星，期间的最大之间的时间亮度是6天，平均亮度（或大小）的星是5，它的亮度变化±0.25级。找到的函数模型的恒星的亮度随时间（天），T（假定在t = 0的恒星的亮度是5，这是增加。）the star as a function of time (in days), t. (Assume t
The non-stationarity of the signal (where statistics are a function of time, Say mean, among other statistics, is a function of time) implies that you can only assume that the statistics of the signal are constant over short periods of time. There is no way of arriving at such a period...

describe有绘画的意思，所以这种描述一定要带实例，图片，模型等更为形象的实体。而与之对应，recount来源于relate，relate侧重从逻辑（两事物的联系，关系）描述，recount的基本意思是relate in detail，也就是说recount是详细的一种抽象描述。当然，口语中管不了那么多，可以互换。建议以后碰到需要对词语深层...
