Connected with four intercepting devices, e .g. coils target, sky-screens and light-screens, it was able to measure the flying bullet in any pairs of them. The final velocity was directly displayed o n the panel. Connected with four sky-screens,it can measure the position where the flying bullet touches on the target.

配接线圈靶、天幕靶和光幕靶等区截装置，四个通道两两任意配对即可实现对飞行弹丸速度的测试，速度值可直接在仪器面板上显示，如果配接四个天幕靶，可实现弹丸着靶位置的测试。

In this approach ,the sketch is designed with simple elements such as points , segments, circles or Child-Graphs which is combination of above simple elements ;geometric elements is designed in sequence can implement the function of unwell defined(less-constrain) parametric design.2Dand 3D constrains is treated consistently.

不同于常见的用底层图元进行设计的二维全约束求解方法，提出并实现了一种基于子图的序列化草图设计方法。使设计者既可用通常的点、线、圆弧等的基本图元，又可用高层的子图设计，可加快设计过程；序列化设计求解方法可实现变量化设计；基于标识的约束模型，使该方法可统一二、三维约束求解。

That is,govemment should avoid and correct not only the possible market failure inthe traditional economy system, but also failures in natural system affectedby economy system; accelerate not only achievement of inner-generationequity, but also achievement of intergeneration equity.

而在可持续发展的实现过程中，政府所面临的最大挑战，莫过于创造出一个使社会的不同利益集团都对可持续发展变革所带来的利益格局变动可以接受和较为满意的"游戏规则"，由此指出了政府能力的提高对可持续发展实现的必要性。

The image collecting parts mainly complete the conversion of the optics photograph to the image that can be treated by the computer. In this step, the pictures of teeth are shot by CCD and store in the compute at the aid of the video collecting cards. The image processing parts realize the geometric transformation, color adjusting, enhancement, measurement and some specially good effects of the collected images. And at the assist of the image processing, the more image information of dental images is exploited, so that the odontologist can diagnose more accurately.
