描述了一个能够快速精确地对三维人脸姿态进行自动估计的系统,提出了利用人脸的反射对称特性自动估计三维人脸姿态的方法,通过扩展高斯图像及最小包围球来得到三维人脸对称平面,利用搜索得到的鼻尖顶点对人脸进行估计,然后对估计在规定范围内进行修正,最终得到精确的估计结果。

以磷矿料浆为介质,分别测量了流体穿过单个孔板和连续穿过两个相距一定距离的相同孔板产生的轴对称射流的长度和宽度。
6) reflected shock wave
反射激波
1.
A weakening reflected shock wave method in oscillating tube;
一种削弱振荡管内反射激波能量的方法
2.
The results indicated that the overpressure of reflected shock wave was much stronger,which was about 2 times higher than that of incoming shock wave.
结果表明反射激波超压明显增强,约为入射激波超压的3 倍,并可引起动物肺和胃肠道损伤;绕射激波的一次激波超压明显降低,约为入射激波的1/3 ,二次激波与距挡板的距离有关,当距离为挡板高度的1/4 和2 倍时,超压低于入射激波,距离为挡板高度的1/2 和1 倍时,超压稍高于入射激波,提示该处激波有叠加现象,实验动物均未见明显内脏器官损伤。
补充资料：轴对称
也称“线对称”。如果把一一个图形沿着某一条直线折过来，它能与另一个图形重合，那么称这两个图形关于这条直线成轴对称。这条直线称为对称轴。如果两个图形关于某直线成轴对称，那么对应点的连线被对称轴垂直平分。
