It is shown that the penetration rate is higher with smaller incidence angle. The central segment of the flight line is 1.6 times of the right most and left most sections, and 1.3 times penetration rate of next right and next left sections.

实验结果显示，当雷射入射角越小时，穿透率越高，反之亦然，航带中间分带穿透率约是面向航向最右五分之一及最左五分之一分带的1.6 倍，是由右方起第二个五分之一及第四个五分之一分带的1.3 倍。

The diffraction theory of Kirchhoff is applied to the four-pinhole aperture diffraction screens, the intensity, the zero-contour of the real and imaginary parts of complex amplitude and the phase distribution in deep Fresnel diffraction region are simulated, and it is found that the bright spots in interference field show central symmetry distribution. When the observation plane close to the diffraction screen, the zero-value points of light intensity can form line segment, on which the eccentricities of the light intensity isoline are close or equal to 1, the intensity changes very fast on both sides of the zero-line of light intensity.

利用基尔霍夫衍射理论计算了四圆孔径衍射屏在菲涅尔深区形成的的干涉光场的强度、零值线和相位的分布，发现干涉光场亮斑关于中心呈对称分布，在距离衍射屏较近的观察面上，光强值为的零点组成光强零值线段，该线段上光强等值线的离心率都接近或等于1，其两侧的光强值变化非常剧烈。

The results show that theheritabilities were 0.36～0.51 for body length, 0.14～0.24 for cephalothorax length,0.25～0.50 for abdominal segment length, and 0.04～0.29 for body weight.

本研究在中国对虾"黄海1号"选育研究的基础上，进行了生长和抗逆性状选育的初步研究。

Based on Bezier curve continuance of first－order and second－order derivative, the characteristic vector equation of two Bezier curve is presented in point of intersection. The algorithm is not only of high accuracy with all of the interpolated points being on the curve theoretically, but also of very high speed in the real－time interpolation processes. The interpolation velocity does not change and the segment tolerance of interpolation can be control by selecting the parameter in cerement rationally every time.

为保证两段Bezier曲线在连接点处一阶导数、二阶导数连续，导出了两段Bezier曲线特征向量应满足的关系方程，Bezier插补法不仅在理论上可使所有的插补点落在曲线上，而且实时插曲补速度高，每次插补时可合理地选择参数增量，能使插补速度保证不变，也可控制弓高误差。

Firstly, the new watershed transformation using extended chain code was introduced. Then a new region merging method for solving over-segmentation was discussed. Experiments show the new algorithm can segment the road regions correctly.The structured road edges can be represented by straight line or segmented lines.

首先在分析经典分水岭变换算法的基础上，提出了一种新的基于扩展链码的快速分水岭变换算法，使得分水岭变换更利于实时应用；然后通过对过度分割产生原因的分析，提出了新的基于区域灰度和位置约束的过度分割解决方法，并在道路区域分割应用中取得了良好效果。
