n.隨機(jī)變量

Main components analysis method could eliminate the colinear among all the variate and reduce variate quantity. 該方法可消除各變量之間的共線性，減少變量的個(gè)數(shù)，結(jié)果直觀；

Results: Alter variate transformation by clustering, the data was more similar to normal distribution. 結(jié)果：指標(biāo)變量經(jīng)聚類變換后，資料總體更接近于正態(tài)分布。

Distribution and transfusion of the geostatic pressure variate in company with mining space in underground mining. 地下開采中地壓分布與轉(zhuǎn)移隨開采空間變動(dòng)而變動(dòng),不同的開采順序會(huì)帶來不同的圍巖穩(wěn)定性。

The improved algorithm adopts adaptive crossover and mutation variate according to the adaptive function value. 改善的算法采用自適應(yīng)的交叉和變異算子,讓交叉和變異概率隨適應(yīng)函數(shù)值的變化而變化。

In this peper,the side clearance of gears is classified into two parts: stochastic variate and stochastic phasing side clearance. 將齒輪副側(cè)隙劃分為隨機(jī)變量側(cè)隙和隨機(jī)相位側(cè)隙兩部分。

adj.多變量的

adj.二變量的
