The friction performances of carbon face were investigated with an inertia friction tester.The torque curve of carbon face was ideal,the coefficient of static friction was lower than that of dynamic in 0.28 MPa,the friction coefficient of static and dynamic decreased with the braking pressure increasing.To the fiber face,the coefficient of dynamic fric...

结果表明：碳质层的摩擦力矩在制动初期上升较快，中间过渡区平稳，尾部翘起较小；在制动压力小于0.28 MPa时静摩擦系数小于动摩擦系数，且动、静摩擦系数均随制动压力增加而减小；相对纤维层而言，采用碳质层摩擦时摩擦力矩曲线形态更好，连续制动时摩擦系数波动较小，磨损率低且能够有效保护偶件，是1种静/动摩擦系数比较低且适用于高载荷工况条件下使用的摩擦材料。

The research shows that gas concentration shows generally an increasing tendency along the working face airflow direction, from 0.095% to 0.18%, under the effect of gas drainage points, up-and-down changing locally; gas distribution in a transect of working face is unequal, under the effect of gas emission, ventilation and drainage, the gas concentration near coal wall is larger than that near goaf, which is a concave function distribution within a distance of 1876.5 m from the inlet of working face, after greater than 76.5m, which is a decreasing distribution from coal wall to goaf.

研究表明，该工作面瓦斯体积分数沿风流方向总体呈逐渐增加趋势，介于0.095%~0.18%之间，受瓦斯抽放点的影响，局部有起伏变化；工作面横断面瓦斯体积分数分布不均匀，受瓦斯涌出、通风和抽放的影响，靠近煤壁侧瓦斯体积分数要高于采空区侧，在距离进风口约18~76.5 m范围内为凹函数分布，大于76.5 m之后，从煤壁至采空区为单调下降函数分布。

Face detection system A new design of face detection system is proposed based upon color-based skin-like region segmentation and neural network-based face distinguishment.

人脸检测系统在对基于颜色的皮肤区域分割和基于神经网络的人脸判别方法进行研究的基础上，本文提出一种新的人脸检测系统设计。

In the detection process,detector can rapidly wash out the sub-window which is unlike face through the front of simple stronger classifiers;for the sub-window which is like face,in terms of similar degree distributer can dynamically select the back of stronger classifiers to determine whether it is a face.

检测时，对于不像人脸的子窗口通过靠前的结构简单的强分类器快速将其淘汰掉；对于像人脸的子窗口，根据其与人脸的相似程度，由分发器动态地选择后面的强分类器进行判定。

The techniques of the midface rejuvenation develop with the understanding of the aging appearance and the development of the facial anatomy. The earliest form of rhytidectomy only removed a piece of redundant skin, but failed to achieve significant long-term benefit. To achieve a more durable benefit, numerous adaptations of face-lift techniques are devised, including SMAS face-lift, malar fat elevation and extended supraplastysmal plane face lift. The subperiosteal approach was firstly performed in 1980s. Youthful curve was detailed by Little William in 2000. To obtain the architectural ogee, the approach of volumetric sculpture, also named three-dimensional rejuvenation, was described.

随着整形美容外科医生对面部衰老变化的认识和面部解剖学的发展，中面部年轻化手术也随之发生着演变：最初的面部除皱术只是单纯去除松弛的皮肤，但术后远期效果不理想；为获得更加持久的效果，到20世纪70年代开始了一系列面部提升术，包括：各种SMAS提升术、颧脂肪垫提升术，扩大的颈阔肌上面部提升术；到20世纪80年代后期，学者提出为获得和谐的面部容貌应进行骨膜下面部除皱术；而到21世纪初Little William提出了"青春曲线"的概念，并实施了容量雕刻技术，即三维中面部年轻化手术。
