余弦定律

Spherical sine law and cosine law can be used out of high school knowledge and evidence, but evidence ...

球面正弦定律和余弦定律可用高中知识证出，不过证。。。

According to the Source attenuation model, Lambert′s cosine law of diffuse reflection and Phong specular reflection model, 2 equations used to calculate the opacity and intensity of every voxel in the volume data were obtained.

方法由源衰减模型、朗伯漫反射余弦定律和Phong镜面反射模型，推导出计算数据场中每一点的不透明度和明暗度的计算公式，通过旋转光源和视点，来自不同观察方向的感兴趣结构的体绘图被满意地生成。

First of all, this paper selected a wide range of spectral response, short response time, photoelectric conversion efficiency, pn junction area of silicon photovoltaic cells, as the light meters photoelectric conversion of the probe, and it creates a separate probe light and increase to the filter and cosine amended, and separated from the fuselage, better adapted to the cosine law and improve the measurement accuracy and scope.

首先，本文选用了光谱响应范围宽，响应时间短，光电转换效率高、pn结面积大的硅光电池作为光照度计的光电转换的探头，并把它做成一个单独的光探头，并加了以v滤光器和余弦修正器，与机身分离，更加适应余弦定律，提高了测量的精度和范围。

Cosine law of spherical triangles : in the spherical triangle , either side of the hot core corresponding to the cosine of angle equal to each other on both sides of the corresponding hot core product with the cosine angle on both sides of each angle of the sine and the corresponding spherical center piece of any side in the spherical triangle in ...

球面三角形余弦定律：在球面三角形中，任意一边所对应球心角的余弦等于其他两边各自对应球心角的余弦乘积加上这两边各自对应球心角的正弦及任意的那条边在球面三角形中。。。

By adjusting the weight, different component in the volume can be filtered out. According to the Source-attenuation model, Lambert's cosine law of diffuse reflection and Phong specular-reflection model, two equations used to calculate the intensity of every voxel in the volume data are obtained.

由源-衰减模型，朗伯漫反射余弦定律和Phong镜面反射模型，推导出了计算数据场中每一点明暗度的计算公式，通过旋转光源和视点，来自不同观察方向的感兴趣结构的体绘图能被满意地生成，从而避免了对内存中整个体数据的旋转。
