To calculate numerically the radiation of a enclosure within a heteromorphosis cavity, attention was focused on: how to decide the visibility between two surfaces, how to improve the old method of configuration factor computation, how to approximately and efficiently decide the radiation resource of directional, spectral radiation in cavity.

讨论了解决异型封闭腔辐射几何学问题的几种方法：异型封闭腔内，表面间可见性的判断方法；优化异型封闭腔角系数计算的方法；确定异型封闭腔内定向辐射的壁面辐射源的方法。计算了两种结构喷管封闭腔内的角系数，并从角系数的互换性和完整性定理验证了方法的正确性和有效性，为异型封闭腔的辐射计算解决了几何问

The result shows that average background radiation can not be deduced by using mean value theorem in visible light band.

通过计算可以表明，在可见波段，平均辐射不能用中值定理来推导，因而不能用天顶角为45度或135度的天地背景辐射来代替平均背景辐射。

What's more, energy can be passed with the mechanical wave; namely the discharged energy could spread outside, so what we called thermal radiation of light take place.

又因为能量能够随机械波进行传递，即放出的能量能够向外传递，所以也就出现了我们所说的热辐射现象，可见的热辐射即是我们所说的光。

By comparison between SMM HXRBS observation and ground observation of Hα and CaIIK lines, especially through the combined study between SMM HXRBS observation and chromospheric flare models, the results show that: in the initial stage of impulsive phase, there is a correlative relation betweem Hα line intensity and hard X-ray emission; different spike in hard X-ray flux curve represents the burst at different location; the energy taken by non-thermal electron beam is larger than the radiative loss in chromosphere; for the flare studied here, the chromospheric evapporation is explosive; if the chromosphere is in balance between electron beam bombardment and radiative loss, the column mass density at the top of chromospheric flare model can not be taken as measure from the source of electrons and then the total material between the source of electrons and the top of chromosphere can be estimated.

通过一个具体耀斑的SMM HXRBS观测结果与同时基于地面得到的Hα和CaⅡK可见光谱观测结果对比，特别是将硬x谱观测结果与色球半经验模型联立研究，结果显示出：在脉冲相上升段，硬x发射与Hα辐射之间存在对应关系；硬x线光变曲线中不同脉冲爆发分量不太可能起源于同一位置；硬x辐射所反映的高能非热电子总携带能量大于色球总辐射损失；对所研究的耀斑而言，其色球蒸发过程是爆发性的；在详细比较了非热电子色球总沉积和色球辐射损失的基础上，指出半经验模型中色球顶部柱数密度不能看成是从非热电子源度量的，从而估计了色球顶部到非热电子源之间的总物质。

By calculation,these two radiation peaks were related to energy metabolism,and the high 15μm radiation peak was identical to wave length in the midpoint of the wave section of 10～20μm high speed tr...

经推算 ，这两个辐射峰与能量代谢有关；15 μm高耸辐射峰与穴处组织 10～ 2 0 μm高效传输波段的中点波长恰好一致；隔附子饼、隔姜和隔蒜三种间接灸的光谱上亦可见 15 μm的高耸辐射峰。

There are still good relationship between UV,visible,infrared and total radiation in solar eclipse.

日食过程中，紫外辐射、可见光辐射、红外辐射与总辐射之间仍存在很好的相关关系。

Although these molecules allow radiation at visible wavelengths, where most of the energy of sunlight is concentrated, to pass through ,they absorb some of the longer-wavelength, infrared emissions radiated from the Earth's surface,radiation that would otherwise be transmitted back into space.

尽管这些分子允许可见波长的辐射通过，在大部分的太阳光能量在这里汇聚，他们能吸收从地球表面发射的波长更长的红外线辐射，如果不这样的话，这些辐射就可以被传回太空。

The luminous flux is visible component that is defined in radiant flux divided by relative sensitivity of human eyes over the visible spectrum.

光通量是可见的组件，它是在辐射通量以人眼的相对灵敏度分歧可见光谱定义。

Based on recent based on precomputed radiance transfer techniques, this paper proposes a novel method for real-time editing object material under complex environment lighting. First, we precompute the visibility for each vertex as a precomputation stage; Next, at rendering stage, we on-the-fly compute bidirectional reflectance distribution function. Finally, we render the object material by looking up visibility of each vertex.

为了在环境光下对模型表面的材质进行实时编辑，提出一种基于预计算辐射传输的算法：首先预计算环境光相对于模型表面每一个顶点的可见性；然后在绘制时实时计算物体表面的双向反射分布函数；最后通过查找环境光相对于模型表面每一个顶点的可见性，快速绘制出物体表面材质。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.

气候直方图是将所收集的降水量测定值，分为几个相等的区间作为横轴，并将各区间内所测定值依所出现的次数累积而成的面积，用柱子排起来的图形，也叫做柱状图。
