By adopting an intracaity flat surface with low reflectivity and controlling the ratio of subcavity lengths, the repetition rate of this compact femtosecond Cr:forsterite laser can be multiplied from 100 MHz to 500 MHz in femtosecond regime. Repetition rate higher than 1GHz can also be achieved.

接著我们置入一个低反射率的腔内平面，将共振腔分为两个次腔，透过次腔长度比例的控制，我们可以将飞秒脉冲的重覆率从100百万赫兹倍增到500百万赫兹，甚至到更高的十亿赫兹以上。

The working process of scroll compressor is analyzied in detail, and the mathematic models describing the state parameters of working fluid in suction, compression and discharge process are presented respectively. The analysis of heat transfer and leakage among these processes is also performed.

文中详细分析了压缩机的工作过程，分别建立了描述压缩机吸气腔，工作腔和排气腔内介质状态参数的数学模型；建立了传热量和泄漏量计算模型，对压缩机各腔进行了传热和泄漏分析。

Some cell dropped into the cavity and became free. Thrombosis or part organization could be seen. The internal elastic layer became thin, disappear or broken. In internal and middle layer existed fibroblasts, fibrocytes and collagen. Some of the wall indicated hyaline change, soomth muscle cell decreased greatly. The massive inflammatory cells invaded the middle and external layer. There were many foam cells in the capsule tissue. Cytoplasm was filled with fatty tissue and cholesterol. some cavities were full of thrombosis. Some thrombosis was fibrosis, the bottom was organization. The surface of the thrombosis existed red blood cell and librae.(2)Elatic fibrila staining: the internal elastic menbrane almost completely disappeared, the intact internal elastic menbran could be seen in the new small vessels.
