In this Papar, the reflection and transmission Properties of EM waves incident on a inhomogeneous and lossy plasma sheath with arbirary profile are discussed by using finite element method,The prarameters of profile takes of the fluid fields data of viscus shock layer for a typical re-entry vehicles.Starting from the virtual work principle,first of all,the variational equ-ation of EM propagation throush the plasma sheath is derivated and then the finite element equation is developed from the veriational equation,The element matrix for EM propagation through the plasma sheath with an arbitrary profile is constructed by applying a function of linear interpolation and numerical results are discussed. Our conclusion is that the FEM is suitable for computation of radio waves through plasma sheath with an arbitrary variable profile.

本文用有限无法求解了电磁波穿透具有任意密度剖面的非均匀等离子体鞘套时的反射和透射问題。鞘套的剖面参数选自典型再入飞行器的粘性激波层平衡流场数据。利用虚功原理和线性插值函数从Helmholtz方程导出有限元方程。鞘套按对数剖分为31个单元。然后,分别对频率f=400MHZ,4000MHZ和10GHZ时,计算了鞘套内的场值及反射,透射和吸收系数。并估算了信号的总功耗。误差分析表明,计算结果是令人满意的。与其它方法相比较,本文所给出的有限无法是简捷而精确的,所以该方程适于计算波穿透具有任意的而且变化剧烈的剖面的等离子体鞘套时的损耗

Global, near-infrared, visible and ultraviolet radiation upon sugarcane fields in the Zbujiang Delta, as well as their reflection, transmission and absorption were measured in 1982 by using EKO pyrancmeters with WG-295, GG-395, RG-715 filters. It is shown that.1. Under clear sky, when the sun's altitude is higter then 35°, the proportion of di ferent spectral lands to the total are as follows, infrared 53%, visible 43%, ultraviolet 4 %. For annual average, visible radiation accounts for 48%.2. The albedoes for infrared radiation on different surfaces follow such an oder as:green plant the highest (on v/hich the albedo is more than 50%), soil the second and water the lowest, while for visible radiation the order is soil, water and green plant.3. The responses of sugarcane to visible, infrared and global radiation are quite different, as shown in Table 2.The relationship between reflection of visible radiation (PAR) and that of near-infrared radiation (NIR) isPARrefl =0.10lNIRrefl- 0.004 The relationship between transmission of PAR and that of N7R isPARtrans = 0.12NIRtrans + 0.03 And the relationship between obsorption of PAR and that of NIR is

The study of this experiment mainly shows that:As the light with the wave-length of 330nm-820nm irradiates on the visceral organs of human body,the rule of reflection,tansmission and absorption is occured.It indicates that the curves are basically similar,thoughthe tissue strutures of man's visceral organs are different,and the absorption peak appears thssame as that from blood light.Thus,this experiment provides a useful basis for light treatmentand protection for human body.
