At the start of the combat damage step, if at least one attacking or blocking creature has first strike (see rule 502.2) or double strike (see rule 502.28), creatures without first strike or double strike don't assign combat damage.

在战斗伤害步骤开始时，若至少一个攻击或阻挡生物具有先攻异能（见规则502.2）或连击异能（见规则502.28），则不具有先攻和连击异能的生物不在此时分配战斗伤害。

This article studied main performances of 50 tractor linkage operation double-acting clutch, introduced emphatically checking method and the step about main performance of the clutch, and the key problems in design and use of this clutch were pointed out.

对50拖拉机联动操纵双作用离合器的主要性能指标进行了研究，着重介绍了该离合器主要性能的验算方法及步骤，并指出离合器设计与使用中的关键问题。

However, in some situations, models are hard to satisfy these assumptions at the same time. We meet a number of random errors with serial correlation and heteroscedasticity in practical problems. The rationality of these assumptions for random errors is doubtable. Therefore, it is necessary to test for correlation and heteroscedasticity in regression, which is an important step of dealing with regression problems and plays an important role in theory and practice.

但实际问题中，回归模型很难同时满足Gauss-Markov的三个假设，人们在实际问题中发现许多随机误差出现序列相关和方差不同的现象，因此对回归模型的随机误差的独立性和方差齐性的假设产生了质疑，从而展开了回归模型的相关性和异方差检验的研究，它是处理回归问题的重要步骤，在理论和应用上都有十分重要的意义。

However, the rationality of this assumption of homoscedasticity of random effects is doubtable. Therefore the verification for heteroscedasticity of random effects is absolutely necessarily and important for dealing with the regression problems in theory and practice.

因此观测数据的随机效应方差齐性检验是非常必要的，它是处理回归问题的重要步骤，在理论和应用上都有十分重要的意义。
