In this paper, the adjointness of the product of two differential operators generated by a third order normal and singular symmetric differential expression in the limit-circle case is discussed. The necessary and sufficient conditions which make the product operators being the adjoint operators obtained by the matrix analysis and calculation. At the same time, the adjointness of the product of the power and adjointness operator obtained.

本文首先讨论了正则和奇异两种情况下两个极限圆型三阶对称微分算式生成的微分算子的乘积的自共轭性，运用矩阵分析和计算，得到了乘积算子为自共轭算子时边界应满足的充分必要条件，同时得到了幂算子的自共轭性、自共轭算子乘积的自共轭性等乘积算子的其它若干性质。

Results predicted by this method are compared with experimental data and the accuracy of this method is found to be very good within the constraints of slender body theory. This method can quickly and accurately provide aerodynamic force coefficient for percept and preliminary design of the non-circular cross section missile.

MG7 AT adopts small style equipped with traditional particular round, independent big racing car, overly aggressive in manner like a cheetah showing motive quality and character generated from a racing car. Reticulated grid is something of BMW as if telling us a historical relationship with BMW while the accessorial decorated bar on the periphery in strong and fashionable feature with the added cheomplate decorated bar both at front and back is the complementary to former metal wire, which proves more confident. Joining with cheomplate decorated bar on the high waistline, side window and afterbody enhances the modern feeling of the whole car as well as injects sumptuous feature. Wheel hub with individuality and motive feeling highly has won extensive praise from fans for cars.

MG7 AT采用了小脸造型，传统而独特的四圆、独立赛车大灯，个性张扬而激进，如同猎豹一般，显现出MG运动的气质和出身赛车世家的血统；双肾形网状格栅颇有些宝马的神韵，仿佛在向人们诉说着当年与宝马的历史姻缘，而外围增加的镀铬装饰条有力而时尚；前后保险杠上也增加了镀铬装饰条，与原有的金属腰线相得益彰，更显自信；车尾则在高腰线、侧窗和尾部加入了镀铬饰条，增强了整车的现代感，也增添了全车的华贵；轮毂造型更有个性，也更具运动感，在车迷中也是倍受好评。

First,skin regions are detected based on YCbCr model of skin color;each block is morphologically processed in order to smooth out the biconvex and small backdate and to fill holes.Then,skin regions are segmented.At last,a disk template is used to find the location of eye and mouth.

方法首先根据YCbCr肤色模型检测出肤色区域；用数学形态学的膨胀和腐蚀方法进行肤色处理，平滑了边界，同时消除了肤色块的连通；再利用圆盘结构元素对人脸区域做闭运算，从而得到人眼和嘴的位置。
