Considering the effect of the change of ambient light on the navigation system of the car, an image processing algorithm with adaptive dynamic threshold is proposed to track the change of ambient light and provide an anti-jamming way for the navigation system with short operating time required.

考虑到环境光线的变化会影响导航效果，提出了一种自适应动态阈值图像处理算法；该算法运算量小，能跟踪环境光线的变化。

Direct difference is sensitive to noisy data, so a threshold limitation is given, which can not only filter the result from noisy data but also pick edge points up according men's desire. On the other hand, artificial intelligence is used for segmentation in reverse engineering. Because the essence of segmentation is clustering similar characteristics and self-organizing feature mapping is one function of neural network, SOFM network is used for segmentation in the thesis, coordinates and normal of data points is took as the characteristics vector.

第二种方法，基于双向角度微分的边点提取法，针对三维正交模型采用基于截面线的方式组织数据，此方法比基于曲率半径方法更简洁，不用进行曲面拟合，大大提高了计算速度；计算过程中由数据点的直接差分逼近微分，但直接差分对数据误差敏感，为此，本文提出了阈值过滤的方法，一方面过滤了数据误差在计算结果中引起的噪音，另一方面可以按照设计意图控制边点的提取；来决定是否提取光滑交接的边点。

This procedure is based on the achievement of the maximum threshold, the image can be processed.

详细说明：本程序是基于最大阈值法实现的，该功能可以对图像进行处理。

However, the threshold at which this distinction was made, and whether it was based on in-group favoritism or out-group derogation, was influenced by the nature of the situation and the task participants performed.

然而，这个区分的界线以及这个界线是基于内群体偏爱还是外群体贬损，受到情境的性质和被试所执行的任务的影响。

But, on one side of the portal, and rooted almost at the threshold, was a wild rose-bush, covered, in this month of June, with its delicate gems, which might be imagined to offer their fragrance and fragile beauty to the prisoner as he went in, and to the condemned criminal as he came forth to his doom, in token that the deep heart of Nature could pity and be kind to him.

然而，在大门的一侧，几乎就在门限处，有一丛野玫瑰挺然而立，在这六月的时分，盛开着精致的宝石般的花朵，这会使人想象，它们是在向步入牢门的囚犯或跨出阴暗的刑徒奉献着自己的芬芳和妩媚，借以表示在大自然的深深的心扉中，对他们仍存着一丝怜悯和仁慈。

But, on one side of the portal, anti rooted almost at the threshold, was a wild rose-bush, covered, in this month of June, with its delicate gems, which might be imagined to offer their fragrance and fragile beauty to the prisoner as he went in, and to the condemned criminal as he came forth to his doom,in token that the deep heart of Nature could pity and be kind to him.

然而，在入口的另一面，几乎就在门槛上生了根的，是一丛野玫瑰，它在这六月的天气里，缀满了宝石般晶莹的花朵。这也许可以设想，这些花朵要把自己的芳香和娇艳献给那步人牢房的囚犯，献给那跨出牢房去接受极刑的死囚，借以表示造物主的内心对他的同情和仁慈。

The first phase array ofthe AS γ experiment began to run in June 1990. The first phase array thatconsists of 49 plastic scintillate detector has an angle resolution of 1°, atrigger rate of 20Hz and a threshold energy of about 10TeV. The second phasearray was finished on the base of the first phase array in 1994, and after that, apart of the second phase array was made high density.

一期阵列由49个塑料闪烁体探测器组成，探测阈能为10TeV左右，事例触发率为20Hz，角分辨率小于1°。1994年在一期阵列的基础上进行了扩建，扩建后阵列比一期阵列有效面积增大8倍，随后进行了部分加密，建成二期／加密阵列。
