由曲线而成的

A human model using polynomial convolution surface is presented which is modeled by articulated skeletons convolved with some kernel function. The convolution surface and curve correspondence theorem under orthogonal projection is presented. The human contour is approximated with a convolution curve and 3D human pose can be estimated using a nonlinear optimization algorithm.

首先建立了一种新颖的多项式密度卷积曲面人体模型，该模型由连接体线骨架与某种卷积核卷积而成，整个曲面是一张连续曲面，调节多项式和半径参数可以让人体任意变形；给出了正交投影下卷积曲面和曲线对应的概念和相关定理，为二维的图像轮廓和三维人体模型之间建立对应关系；根据正交投影下卷积曲面与曲线对应定理，用卷积曲线去逼近人体的图像轮廓曲线，从而估计和恢复出三维人体运动姿态。

The rheological character of a polymer often appears as shear-thinning. Most polymers behaviour in a solution can be explained by the polymer chain or hard sphere theory. Other than that, shear-thickening polymer solution also exists. Its behavior can be explained by dilatant theory, which suggests that the shear-thickening of the solution is due to the swelling of the polymer particles. This phenomenon often occurs in suspension or emulsion. Solution exhibits a mixed behavior can also be found whose behavior is such that shear-thinning occurs under low shear force and shear-thickening occurs under high shear force. Under this circumstance, the viscosity versus shear force graph exhibits a spoon shaped curve. The rheological study can be applied to the dispersion of paint which can predict the dispersion effect of various polymer materials in solution.

中文摘要一般高分子聚合物溶液的流变行为多半呈现剪稀(shear-thinning)的现象，而大部分的高分子在溶液中的行为是以分子链或是硬球观点来解释，另外也有剪稠(shear-thickening)现象的高分子溶液，其流变行为则是以膨胀体观点来解释，即在高剪切力下，由於高分子团体积变大而使溶液黏度升高，这在悬伏液、乳液等常见；但也有在低剪切力下，溶液具有剪稀的行为，而在高剪切力下却成现剪稠的行为，在黏度对剪切力作图时，会呈现出一个勾形曲线的图形；流变行为的探讨可应用在涂布材料的分散技术上，以推测不同的高分子溶液对分散效果的影响。

Moreover, the test results are compared with the empirical correlations of reference literatures to verify the accuracy of present pool boiling experiment. The test results indicate the higher boiling incipience and lower CHF value for a new plain surface at first test run and slightly improvement at last two test runs.

结果显示平滑加热面有极高的沸腾起始过热度及明显的沸腾迟滞现象，而比较沸腾次数的实验发现，由於表面成核孔穴被活化的结果，后续实验的起始过热度明显降低许多，沸腾曲线亦向左偏移，且临界热通量也有些微增加。

Methods 22 parients(35 ears)had been tested in three noises, including white noise,speech noiseand babble noise.BN was recorded when 8～12 persons were talking at same time.The monosyllabic phonetic balance word list was made by Shen Ye in 1983 and every list includs twenty-five words,Meantime ,the effect to speech discrimination score curve was tested in different signal to noise ratio.

目的 为了观察传导性聋患者在噪声竞争下言语清晰度曲线及不同噪声对清晰度曲线的不同影响；方法测试22名(35耳)传导性聋患者三种不同噪声竞争下测得的言语识别率结果，这三种噪声为①白噪声(white noise，WN)，②言语噪声(speech noise，SN)，③多人谈话声(babble noise，BN)，即由8～12人同时讲话录制而成，其频谱与言语长时平均频谱接近。
