在使用光学水准仪时，由于眼睛疲劳，现场限差指标计算等原因，精度和速度很难满足我们的要求，而且一般需要6人/组：其中1人观测，1人记录，2人扶尺，2人照灯。

The principle formula error of measuring the refractive index by the method of minimum deviation angle and the method of V-prism .

最小偏向角法V棱镜法测量折射率的原理公式误差。

Based on the method of minimum deviation angle, man can obtain the accuracy of measuring refractive index of glass at 3×10-6 with fine apparatus for measuring angle, but the classical princip1e formula quoted by these literatures have principle formula error about 4 ×10 - 4 order which lead to an erroneous measure result.

在这些测量折射率的方法中，最重要的是最小偏向用法和V棱镜法。推导最小偏向角法和V棱镜法的所有文献都沿用经典的原理公式，而这些经典的原理公式没有考虑到空气实际折射率对被测试样折射率的影响。

In this paper we have point out the error of principle formula quoted by all literatures at home and abroad to measure the refractive angle and the method of V-prism, derive from beginning the right formula of measuring refractive index by the method of minimum deviation angle and the method of V-prism.

本文指出了测量光学材料折射率的最小偏向角法和V棱镜法国内外所有文献的原理公式误差，重新推导了最小偏向角法和V棱镜法测量折射率的正确公式。基于最小偏向角法用精密测角仅可以获得±3×10-6的折射率的测量精度，然而，这些文献沿用经典的测量原理公式却具有-4×10－4数量级的原理公式误差，因此导致错误的测量结果。

Based on many lab test s and a case line, the measuring technique and application Index of Asphaltum road surface of Tongsan Express in Fuiian Province is studied, the quality standard and error controlling area is put forward, the aim is to promote the road quality.

在大量室内试验研究及试验段验证的基础上，对改性沥青混和设计和关键施工工序及质量控制进行了对比并提出了施工质量标准与误差允许范围，为进一步提高路面施工质量起积极的推动作用。

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。

So, the compression of the magnetopause may generate considerable error in Dst index.

这一贡献可以使Dst产生相应的误差。

The research involves constructing network error model, choosing interpolation method, computing and validating integrity index for error correction, calculating user protection level.
