In this case,if we are still based on the stock index returns in the previous period.then bigger bias may occur and we might make error judgement,therefore we should cogitate these factors when studying the return levels.

在这种情形下，如果仍然以前一时期的股指收益率数据拟合模型为依据，对现时期的收益率进行预测等统计推断，可能会产生很大的偏差甚至会造成错误的判断，因此我们在研究返回水平时应该慎重考虑这些因素。

Then the finite element software ANSYS is used to simulate the orthotropic flattened Brazilian disc specimen subjected to diametrical compression, the accuracy of the approximate formula of compression displacement is checked. The formula is further modified with a semi-empirical and semi-analytical approach, and it is shown to have better accuracy than the original formula covering the whole range of orthotropic anisotropic index of rock, the error is less than 6%.

用有限元分析软件ANSYS模拟正交异性岩石的巴西圆盘试样的对径压缩实验；利用有限元分析结果对正交异性平台位移压缩公式进行精度检验，并用半经验半解析的方法，对该公式进行局部的修改，修改后的公式在岩石材料的正交异性指数的整个范围的总体评价上，误差小于6%，具有更好的计算精度。
