Adaptive subdivision is performed only in the areas facing to the viewpoint in the pre-process. And in the each adaptive subdivision, we choose the normal angle of the adjacent faces as the control error to detect whether the approximation is sufficient. Sharp edges are automatically tagged according to the given thresholdθand subdivision masks are designed based on different sharp degrees.

The four-point threshold program of YDS-201 perimetry in the fast screening for visual field defect in glaucoma is better sensitivity and specificity. It is a good method for screening on glaucoma in large population of people because of the short time for examination.

YDS-201视野计四点阈值程序在快速筛查青光眼视野缺损中具有较高敏感胜和特异险，检查用时短，适合于青光眼的视野筛查，是一种在大量人群中快速筛查青光眼的良好方法。

The crucial procedure of contour detection for microscopic image of sprayed droplets and measurement of granularity is to segment droplets from background by producing binary images. The singular threshold is uneffective because the image is very different in illumination. In this paper, a fast maximum entropy image thresholding algorithm based on local gray feature is presented to exact sprayed droplets from background and preserve contours of droplets.

雾滴图像的颗粒提取与测量关键是分割出雾滴与背景，生成二值图像，由于雾滴图像光照不均匀，用单一阈值无法兼顾亮区与暗区，本文提出了一种基于局部灰度特性快速最大熵动态阈值选择算法分割出雾滴微粒并提取雾滴轮廓。

The results show that for unoriented ZnO nanowire thin films, the electric field intensities corresponding to the turn-on voltage and threshold voltage of field emission are 4.7 and 7.6V/μm, which are much lower than those of aligned nanowire arrays.

结果显示，非取向生长的ZnO纳米线薄膜场发射的开启电压和阈值电压所对应的场强分别为4.7和7.6V/μm，场增强因子达10^3量级，具有较阵列生长的ZnO纳米线更为优异的场发射能力。
