bare surface meaning in Chinese
露骨
Examples
- A coat of primer should be made over the bare surface before the main painting
在喷涂主漆前，应在物品的表面刷一层底漆。 - Abstract : because of hard ground surface characters of big bulk densities , bare surface and be disturbed easily , the hard ground surface has its laws about sediment yield
文摘:硬地面由于具有容重大、地表完全裸露、易受人为干扰等特性，因而其产沙特性有其自身的规律。 - 2 ) radar incidence angle and surface roughness correction : to make radar incidence correction and eliminate the surface roughness effects , a wide range of surface parameters ( soil moisture , surface rms height , correlation length , incidence angle ) was input to the ibm model to simulate the effect of surface roughness and radar incidence angle on the sensitivity of soil moisture to the radar backscattering coefficient . a simple model was established to simulate the effects of incidence angle and surface roughness . 3 ) establishment of soil moisture change inversion model : according to a modified ibm model simulation results , the bare surface backscattering coefficients can be expressed as a funtion of the dielectric component for a given surface roughness when the surface slope greater than 2 . 0 , which is valid for most nature surface : in above equation , r0 is the surface reflectivity at normal incidence
本研究中，首先利用基于微波辐射传输方程的微波植被模型和积分方程( iem )模型模拟了各种地表土壤水分含量情况下，植被覆盖、地表粗糙度(包括地表均方根高度和相关长度) 、雷达入射角对c波段(频率4 . 7ghz )水平极化( hh )雷达后向散射系数的影响，在此基础上，建立模型消除了植被覆盖、地表粗糙度、及雷达入射角对雷达后向散射的影响，利用多时相50m分辨率radarsatscansar雷达后向散射系数图像反演得到了地表土壤水分变化模式信息。
