"综合"样本法
组合煤岩试样中煤层厚度越大,则其弹性能指数就越大。
It is necessary to research into the burst failure and rock burst tendency of combined sample which is made up of roof, coal and floor.研究顶板-煤体-底板所构成的组合煤岩体试样变形破裂规律及冲击倾向性对于预测冲击矿压具有非常重要的实践意义。
The researchers also did something a lot of researchers do when their sample size is simply too small to study - they combined two groups that are potentially very different.即使样本数量不足于进行研究,研究者们还做了些很多其他研究者们做过的事情——他们把可能性十分不同的两组结合在一起。
