The research work of this paper includes the following several respects mainly: 1, Introduce the method of dubiety excluding to the traditional face detection algorithm based on the model of faces' color, which have improved the accuracy rate of face detection greatly through this method.

提出了一种基于局部几何特征的人脸特征提取算法，根据人脸器官的位置及色彩特征，改进了普通算法在阴影较大的情况下识别率急剧下降的问题。

A predator model with refuge and toxicity is studied. By constructing a suitable Dulac function, it is shown that there is no limit cycle in the first quadrant, thus the globally stability of the equilibrium is proved. Further more, the paper analyzes the influence of refuge, toxicity and harvesting. It is amazing that ① if the death rate of predator is big or the harvesting effort is big, the existence of the predator is unrelated with refuge; if the death rate of predator and the harvesting effort are small, and the refuge is small enough, the population of both species is increased as the increase of refuge;② if d2=0, the increase of d1 has no influence on the prey population, while the population of predator is decreased.

研究一类有避难所、毒素作用和外界捕获影响的捕食系统，通过构造恰当的Dulac函数，证明系统在第一象限没有极限环，从而证明了平衡点的全局稳定性；分析了避难所、毒素、捕获作用对该系统最终种群数量的影响，发现：①当捕食者的死亡率大或其被捕获得多时，两种群的绝灭与避难所的存在无关；当捕食者的死亡率小、被捕获得多且避难所足够小时，随着食饵避难所的增加，捕食者种群数量也随之增加；②当毒素d2=0时，毒素d1的增加对食饵种群最终数量没有影响，而使捕食者种群数量下降。

Indeed given free elderly parents at home, playing games online play typing enrich their later years of life is good, but not as a result of flexible arms and legs, vision and so on, even typing such a simple action would also be very difficult, as children We have to think of a way for them to solve this problem typing, the font will be the candidate words to enlarge the font at the same time make it more clearly on the good, in fact, without the complexity of operation, the input method set up hands-on moving it.

的确年迈的父母闲赋在家，打打字玩玩游戏上上网充实他们的晚年生活是不错的，但是由于手脚不灵活，视力下降等等，即使是打字输入这样一个简单动作也会非常吃力，作为子女的我们就得想办法为他们解决打字输入这个问题，将候选字的字体放大同时使得字体更加清晰就很好了，其实无需复杂操作，在输入法设置上动动手就可以了。

Both accumulation of ROS and reduction of GSH-PX have relation with diabetic renal dysfunction, which also causing execration increase of urine MCP-1. ROS via inflammation reaction can damage diabetic renal function.

ROS合成增加、GSH-PX的活性下降均参与了糖尿病肾脏的损伤，并使代表肾脏炎症反应的尿MCP-1随尿排出增加，推测ROS介导的炎性反应在糖尿病肾病的发生、发展中发挥了作用。

In contrast to Boudot's protocol, our method reduces an exponentiation operation; the communication quantity decreases from 16176 bits to 13222 bits, and the communication efficiency increases by 18.26 percent.

The mode of the friction saw cutting has been founded and the theory of that one has been put forward according to analysing the process of friction saw cutting, which make use of friction and extrusion to increase temperature of the area of work cutting and make the hardness and strength of work reduce obviously.

通过对摩擦锯切过程的分析，建立摩擦锯切模型，提出了摩擦锯切的原理，主要是利用挤压变形和摩擦，提高工件切削区的温度，使工件的强度和硬度显著下降，同时，设法保持刀具的温度在300℃以下，使硬度保持不变，从而实现了刀具硬度与工件硬度比的大量增加，完成超高速切削。
