Finally, the splats are rendered from far to near by using elliptical weighted average filtering.

首先根据构造的移动最小二乘曲面计算采样点的表面几何属性，然后根据协方差分析确定点元在其切平面上的椭圆表示，最后采用椭圆加权平均滤波从远到近单遍绘制各点元。

Based on moving least squares surface, the differential properties of each sample point on PSO are first evaluated. In terms of covariance analysis, the elliptical splat of sample point is then determined on its tangent plane. Finally, the splats are rendered from far to near by using elliptical weighted average filtering. According to the differential properties, moreover, the suggestive contours of PSG are attained so that non-photorealistic rendering of PSG is realized.

首先根据构造的移动最小二乘曲面计算采样点的表面几何属性，然后根据协方差分析确定点元在其切平面上的椭圆表示，最后采用椭圆加权平均滤波从远到近单遍绘制各点元，此外，根据表面几何属性确定点模型的轮廓线，实现了点模型的非真实感绘制。

The results showed that compared to participants of other three groups, neglect patients produced significantly more errors, longer reaction time, and greater number of saccades. They started their search to the left or right of the middle and employed inefficient search strategies. In particular, neglect patients performed worst when the target appeared on the far-left visual field.

实验结果发现，除跳跃眼动的平均长度外，忽略症病患的各项表现皆显著较差：他们均容易忽略患侧空间的目标物；即使可以侦测到，其反应时间和跳跃眼动的数目皆显著增加，主要从近端的两个区域开始扫描，且无法采取较一致且有效的策略来侦测目标物。

According to the historical monthly runoff data of Yele reservoir on Nanya river, the durability property concealed behind the complex non-linear characteristics of runoff may be discovered by using the method of rescaled range analysis.

基于南桠河冶勒水库月平均径流资料，运用重标极差分析方法揭示了径流复杂的非线性特性隐藏下的有序性，即持续性特性。

Multiple regression techniques were used to discern whether increasing case number was associated with improved perioperative and 2-year minimum radiographic and clinical outcomes. The 96 cases were divided into 4 equal quartiles of 24 cases/group (i.e., Q1-Q4) and compared using analysis of variance measures.

使用多元回归技术辨别是否随着病例数的增加，初始和2年后围手术期的最小放射线剂量和临床结果有差别。96例患者被分成平均的4组，每组24人（i.e。，Q1-Q4），并使用方差分析的方法进行比较。

The averaged onset time is the 28th pentad (72 pentads/year) for the EAM and the 32nd pentads for the INM coincided with the results obtained from the 15-year mean wind and geopotential fields. During the 15-year period, the early onset years are 1984,1994 and 1996 and the late onset years are 1982,1985,1987,1991 and 1993 in the EAM region.

结果表明，IWH是一个能够反映亚洲热带夏季风环流主要特征、适合用于确定季风建立迟早的指数；在1982～1996年期间，在东亚季风区，热带季风建立较早（比平均情况早2候或以上）的年份有1984、1994和1996年，建立较迟的年份有1982、1985、1987、1991和1993年；东亚热带季风建立时间的年际变化（标准差为2.3候）比印度季风大，反映东亚季风区环流变化较印度季风区更为复杂。

In order to make operating rates comparable, I have normalised the data so that, for each country, the long-term average operating rate as well as its variance are equal to the parameters of the US series.

为了使开工率具有可比性，将数据标准化，以便使每个经济体的长期平均开工率及其方差和美国的参数标准相符。

Encouragingly, the proportion covered in sub-Saharan Africa, the worst-affected area and the one with the least developed health infrastructure, is slightly higher than the global average, at 44%.

令人鼓舞的是，在撒哈拉沙漠以南的非洲这个世界上感染最严重、同时卫生基础设施也最差的地区，药品的覆盖比率已经为44%，比全球平均水平还要高出一点。

From the viewpoint of energy efficiency of cooling towers and underground thermal balance, recommends the operating mode by setting the average water temperature of buried exchangers or by setting the difference between the water temperature of buried exchangers and the wet-bulb temperature of environment.

从冷却塔运行节能及地下冷热平衡的角度考虑，建议采用设定地埋管换热器流体平均温度或设定地理管换热器流体温度与环境湿球温度的差值的控制策略。

Average annual precipitation data of the last 30 years from 1961 to 1990 at 186 meteorological stations in Gansu and its nearby regions was compared and analyzed by Inverse distance weight tension, Spline, Ordinary Kiging methods. The result showed that the three interpolators could reflect the spatial distribution of precipitation of Gansu province. Ordinary Kriging method was the most effective, followed by Spline methods and Inverse distance weight tension method.

利用甘肃及其周边186个气象台站30年平均降水资料，分别采用了反距离加权法(In-verse distance weight tension)、样条函数法和普通克里格法等3种常见的空间内插方法较为系统的分析比较了这3种内插方法插值结果，结果表明：3种方法的结果都基本上反映了甘肃降水大体空间分布规律，而普通克里格法的插值效果最好，样条函数法次之，反距离加权法较差。
