The scintillation CsI was also calibrated with protons of 15, 20, 23MeV. The average energy calibration is 1. 047MeV per channel. Energy calibration for heavy ions was completed with multiplication factor 1/12. 75. The energy calibration is around 1. 1MeV per channel for oxygen ion and iron ions when energy deposition is less than 50MeV in each detector.

对铁离子而言，铁离子的四个能量点在ΔE〓探测器中的能量均超过50MeV，能量信号放大电路此时已进入饱和状态，当铁束能量为120MeV时，离子进入到ΔE〓探测器中，此时在ΔE〓中能量沉积低于50MeV，没有达到电子学系统的饱和值，能量刻度每道为1.1MeV／道，这些与氧离子的标定结果是一致的，饱和只是对于低能重粒子会出现这种情况，对于中高能重离子这种现象就会消失。

It was found that count rate reduces while gas flowing rate increases.This fact can be explained by the lasting time of gas in the scintillation chamber.

发现计数率随气体流量的升高而降低，并用氡气在闪烁室中的通过时间予以解释。

It is not to be confused with scintillation or dispersion.

这是不容混淆与闪烁或分散。

And at the beginning of the scintillation, the plasma has a large vertical velocity, which can also cause the uncertainty of the zonal drift velocity.

另外，在闪烁刚发生时，不规则体纬向速度起伏较大，这可能与不规则体的随机起伏以及等离子体泡产生时垂直速度较大有关。

In this paper, effects of atmospheric factors to Ka-Band earth-space links are analyzed, and the total fade distribution function is derived. With the scintillation prediction model, monthly averaged standard deviations and monthly percentage time averaged fade of scintillations for some of referential earth stations of our country are computed.

On Earth-space paths, this beam scintillation index model is significant for the laser imaging, tracking, controlling and guiding, and laser satellite-Earth communication.

高斯波束的斜径闪烁指数模型的建立发展了湍流闪烁理论，将对地－空路径光通信、成像、遥感、激光制导和强激光系统的设计和应用具有重要的实际意义。

Finally, on Earth-space paths, by applying a modification of the Rytov method that incorporates spatial frequency filter function under strong fluctuation conditions, a tractable model is developed for the scintillation index of a Gaussian optical beam wave that is valid under moderate-to-strong irradiance fluctuations. The scintillation indexes for collimation Gaussian beam are predicted by this analytic model, based on ITU-R C〓 model.

最后，应用强起伏下引入空间滤波函数的修正Rytov方法，发展了一种易处理且可用于从弱到强起伏地－空路径的高斯波束光波闪烁指数模型；基于ITU-RC〓模型，预测了准直高斯波束的闪烁指数，其结果和理论分析结果相符。
