偏向角

In order to measure accurately the refractive index of optical glass to improve the imaging quality of optical systems,several measuring methods of refractive index for optical glass were analyzed and both foreign and domestic development situations for optical glass measurement were introduced.

为准确测量光学玻璃的折射率，提高光学系统成像质量，介绍了现有光学玻璃折射率测试方法和国内外发展现状，提出了一种利用测量棱镜3个顶角所对应的3个最小偏向角的折射率测量新方法。

The calculation of refractive index is implemented according to the minimum deviation angle measured on our experiment setup.

以艾里的虹理论为基础，提出了一种由二次彩虹条纹图确定最小偏向角的方法，实现了高折射率玻璃微珠折射率的测量。

The fringe of secondary rainbow of the high refractive glass beads is analyzed by using Airy rainbow theory, and a method to be used to determine the position of the minimum deviation an gle according to the secondary rainbow is proposed.

以艾里的虹理论为基础，提出了一种由二次彩虹条纹图确定最小偏向角的方法，实现了高折射率玻璃微珠折射率的测量。

Use the improved method to measure the minimum angle of deflection of a certain prism ;it accords with the experiment demand.

应用改进的方法测量出某种三棱镜的最小偏向角，说明符合实验要求。

In addition, the two surface of the cementing layer is not always strictly parallel. And therefore its deflection angle and transmissivity is different from the value of the order.

另外，胶合层的前后表面并不总是严格平行，因此其偏向角和光强透射比要异于正常情况下的值。

To the femoral neck fracture with neck-shaft angle of less than 135 degree, the fixation with the entry angle of less than 135° can make the neck-shaft angle rising, meanwhile, lag screw's location is easier to trend to the inferior of femoral head, displacement and angle between fracture surfaces satisfy the demand of functional reduction or extroversion reduction, and a satisfied stability is performed in biomechanical test.

对于颈干角小于135°的股骨颈骨折，以低于135 °的进钉角度固定时，能增大颈干角，同时拉力螺钉的位置更容易偏向股骨头颈的中、下部，骨折端的位移、成角也能够符合功能复位的要求，在力学测试中表现出较好的稳定性。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.

气候直方图是将所收集的降水量测定值，分为几个相等的区间作为横轴，并将各区间内所测定值依所出现的次数累积而成的面积，用柱子排起来的图形，也叫做柱状图。
