And the only allowed Raman band in the first-order diamond spectrum near 1332 cm^(-1) decreases and can't be observed in the micro-Raman spectrum of the film. Three Raman band near 1147 cm^(-1), 1364 cm^(-1) and 1538 cm^(-1) lie in the spectrum which are similar to the reported nano-diamond films.

在该薄膜一阶微显微拉曼光谱中，1332 cm^(-1)附近微晶金刚石的一阶特征拉曼峰减弱消失，可明显观测到的三个拉曼散射峰分别位于1147 cm^(-1)、1364 cm^(-1)和1538 cm^(-1)，与己报导的纳米金刚石拉曼光谱类似。

The model of line photogrammetry is the coplanarity condition among the projection center, a space line and its corresponding image line.

直线摄影测量的基本原理是摄站中心、空间直线及其对应的像片直线段间必须满足共面条件，每个像片直线观测值可列两个按条件平差的误差方程式。

The experiments showed that the starch was rich in the extracts because the Radix puerariae is a Chinese herbal with a lot of starch. The starch would be soluble and produced a floccule when water is used as solvent and the extracting system is at high temperature.
