This thesis developed physics model of radiant panel heating and cooling room based on previous studies. Computational fluid dynamics software FLUENT was applied to study the thermal environment of radiant panel heating and cooling room. The distributions of temperature and velocity of rooms of radiant floor heating and cooling, radiant ceiling heatingand cooling and radiant wall heating and cooling are gained.

目前我国的研究大多数侧重水体中溶解态磷的含量和分布，对水体中颗粒态磷的研究相对较少，对总磷的外部补充机制和内部循环机制等方面的研究还有待深入。

Because RFCA in a bipoiar fashion can enlarge lesion surface area without increasing the depth, and its particular lesion distributions involved the electrode/tissue interface and the part between the two adjacent electrodes, there is much opportunity to hit the target in bipolar fashion so long as the orientation of the pathway or the any part of reentant circle is not parallel to the electrode-connecting line, whatever at any angle.

因为双极消融法比常规单极消融法有更大的消融面积但不增加深度，而且其组织损伤分布于两电极与组织的交界面和两电极之间区域，所以只要旁道或折返环路的任何部位的走向与两电极的连线不相平行，在任何夹角下双极消融均比单极消融有更多的击中机会。

No differences were found in the distributions of these polymorphisms between patients with PDR and those with NPDR.

In 1988, Song Dedun and Ding Jing further verified that the distributions whose inverse forms must be explicitly defined could by no means be a prerequisite for using the PWM method, and they applied PWM method successfully to the estimation of parameters in Pearson Type-Ill distribution (P-III distribution) although this sort of distribution nev...

由我国宋德敦、丁晶(1988年)将美国Greenwood等人(1979年)提出的概率权重矩法，应用于P-Ⅲ分布，取得较好效果。本文将PWM法应用于指数Γ分布的参数估计。统计试验结果和实例分析表明，PWM法用于指数Γ分布的参数估计时，具有较好的统计特性。
