In order to describe the random variability of comprehensive actions of rock mass on lining, an equivalent deviation increasing function is put forward.

为此提出围岩物性参数空间等效方差增大函数这一概念，用来反映岩体结构对衬砌综合作用的随机变异性。

There is always a certain degree of random variability in real data, and repeated data sets that have no or almost no variability are powerful evidence of fabrication.

我们的实验结果总是在正确的数据上有一定范围的变动，而小范围的浮动或者根本没有任何数据的变化将是造假的有力证据。

Some research state clearly: random dynamic respond of large fluctuation levels can be given rise to random variability of structure's parameters and sometimes it becomes leading factor.

众多研究工作表明：结构参数的随机变异性可以引起结构随机动力响应的随机涨落，结构力学参数的随机性还可能成为主导因素。
