查询词典 measuring

It can get the three-dimensional profile of the object surface effectively. Because of the cragginess of the three-dimensional surface when sine grating is projected the image of the sine grating is modulated and the modulated image is taken by a CCD camera with an angel compared to projecting direction. After the phase shift measuring method, the phase is gotten. Because the phase is calculated by the phase shift measuring ranges from –π to +π it isn't continuous. The phase unwrapping is necessary to recover the continuous phase about the object shape.

这种方法采用结构光照明，将正弦光栅图像投影到被测物体表面，用与投影方向成一定角度的CCD摄像机获取受物体表面面形调制的变形光栅像，根据数字相移算法计算出相位分布，由于从相移计算的相位被截断在反三角函数的主值范围内，因而是不连续的，必须通过相位展开恢复出连续相位分布，由相位－高度关系最终求出物体轮廓的三维数据信息。

This thesis also discussed the deficiency of index for measuring species association and Cody index for measuring βdiversity.

此外，本项研究还发现了种间联结的一些测度方法及Cody指数的不足，并在此基础上提出了相应的改进方法。

Because fluid pressure and rock stress change during sealed coring process, the degasification and rock pore volume change. As a result, there is difference between laboratory measuring saturation with in-situ saturation. Therefore the laboratory measuring fluid saturation has to be corrected to predict the in-situ fluid saturation.

在密闭取心过程中，由于流体压力和岩石应力的改变，导致流体脱气和岩石孔隙度改变，因此室内测定的岩心含水饱和度和实际油藏含水饱和度存在较大的误差，有必要将室内测定的含水饱和度校正到油藏条件下。
