1. Analysis of covariance is a combination of regression analysis and variance analysis.
   协方差分析足把直线回归与方差分析结合起来应用的一种方法。
2. The data on covariance presently available are here.
   目前所能获得的关于协变的资料都在这儿。
3. The theoretical foundation of the covariance is pertinence of system theory.
   协变性的理论基础是系统原理中的相关性。
