Point clouds from human body surface are first converted into cylindrical polar coordinates and the panoramic range image of human body is created.

首先把人体表面的点云数据转换为圆柱极坐标形式，获得人体扫描表面的全景深度图像表示，根据全景深度图像中的层次信息自动检测人体表面的拓扑特征，并根据拓扑特征把人体分割成5个功能结构。

Using the solar energy transformation electrical energy, does not need the common battery; The indoor daylight lamp and the natural photo source may shake, the moving point installment, may bring in the lively atmosphere and the vigor!!

利用太阳能转换电能，不需一般电池；室内的日光灯及自然光源就可以摇动，动点装置，可引来活泼的气氛与活力！！

介绍了方案的工作原理，根据光学特征点———红外发光二极管的光学特性，运用新型D/A转换器、运算放大器及三极管等构成可程序控制的恒流源电路，解决了发光二极管控制过程中的电流调整困难、工作过程中发热、管耗高等问题。

Price difference and discharge are changed, with respect to this bit sufficient already fatten he.

差价和流量转换，就这点足已经养肥了他。

The results also clearly present the effects of the inertia force, which is represented by the Reynolds number, on both the flow patterns and the vorticity distribution on the bubble interface.

本研究除了在两种典型流场的结果上与先前文献相符合外，更精确的以停滞点的移动形式作判别并发现在两典型流场之间存在著转换流场。

And the integration can be applied to compute river water-level and velocity of stream-flow as monitoring fluvial discharge, especially during freshet.

此外，在讯号分析部份除了针对水面高程进行分析之外，我们也分析GPS反射讯号的都卜勒频移值，利用速度场转换的方式可计算出每个反射点的流速，而在此利用GPS反射讯号与数值地形资料库整合应用，透过整合系统的开发将可提供全面性及近即时性的河川水面高程及流速的量测，更可加以估算河川洪水期之河水流量，用以提供河川洪峰流量之监控。

For reducing boundary distortion area, the elevations of grid DEM are viewed as a discrete sequence under a generalized coordinate, so that the boundary problem of two-dimensional discrete wavelet transform is turned into the boundary problem of one-dimensional discrete wavelet transform, which not only greatly reduces the boundary distortion area, improves the precision of reconstructed DEM data near the boundary, but also decreases the number of zeros adding on the boundary for wavelet transform, and boosts the compression ratio. On the basis of analyzing the distribution characteristics of coefficients in low and high frequency bands, a mixed entropy coding plan is applied, and a high efficient quantizator called"self-adaptive hard threshold"is established, which is helpful for improving the precision of the reconstructed DEM data and for enhancing compression ratio.

为了减小小波变换山区格网DEM数据压缩中边界失真区域，将山区格网DEM高程值视为广义坐标下的离散随机序列，把二维离散小波变换中的边界问题转换为一维离散小波变换中的边界问题，不仅大大减少了小波变换边界失真区域，提高了重构DEM数据边界点的精度，而且减少了边界补零个数，提高了压缩比；通过对山区格网DEM数据小波变换低频区和高频区变换系数分布特点的分析，采取了霍夫曼—游程混合熵编码方案，设计了高效、低失真的"自适应硬阈值"量化器，即对低频区变换系数不进行量化，直接进行霍夫曼编码；对高频区变换系数则先用"自适应硬阈值"方法量化处理，再进行游程编码。

In order to tr a nsform conveniently the direction a l a ngle of a geodesic line into the geodetic a zimuth,the solution of the meridi a n a l convergence is expressed by geodesic coordin a tes of this point.

该解式直接采用该点的测地坐标来求解子午线收敛角，从而能方便地将测地坐标系中任一大地线的方向角转换为大地方位角。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。

The relationship between communicative competence and grammar teaching should be that of the ends and the means.

交际能力和语法的关系应该是目标与途径的关系。
