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，首先利用基於微波輻射傳輸方程的微波植被模型和積分方程（ iem ）模型模擬了各種地表土壤水分含量情況下，植被覆蓋、地表粗糙度（包括地表均方根高度和相關長度） 、雷達入射角對c波段（頻率4 . 7ghz ）水平極化（ hh ）雷達後向散射系數的影響，在此基礎上，建立模型消除了植被覆蓋、地表粗糙度、及雷達入射角對雷達後向散射的影響，利用多時相50m解析度radarsatscansar雷達後向散射系數圖像反演得到了地表土壤水分變化模式信息。In this work, the influences of fabrication process on microstructure, dielectric properties, ferroelectric properties and pyroelectric properties of plt films have been studied. plt films were prepared on the pt ( 111 ) / ti / sio2 / si ( 100 ) substrates by radio frequency magnetron sputtering method and then annealed by rapid thermal annealing process ( rta ) or conventional furnace annealing process ( cfa ). with the help of atom force microscopy ( afm ), x - ray diffraction ( xrd ) and some other apparatus, it was found that : lower substrate temperature ( ts ) was helpful for plt films to form better surface morphologies. with the increase of substrate temperature, the dielectric constant of plt films increased
Afm 、 xrd以及性能測試結果表明:較低的基片溫度有利於形成表面均勻緻密的薄膜，且薄膜的表面粗糙度均方根較小;隨著基片溫度的升高，經過快速退火的plt薄膜的介電常數逐漸增大;相比于傳統退火，快速退火縮短了退火時間，提高了薄膜的介電和鐵電性能;快速退火隨著保溫時間的延長，大部分鈣鈦礦結構的特徵峰的峰強增大，半高寬減小，峰形越來越尖銳，但當保溫時間為80s的時候， （ 100 ）和（ 110 ）峰的強度有所下降，因此保溫時間在60s較為適宜。Taking suspension bridge anchor of runyang highway bridge as project background in this paper, considering undulating angle of rock mass structural plane, angle of mean square root slope method is established by exerting fractal geometry theory. fractal dimension of profile of rock mass structural plane is calculated by above method. and roughness degree is described quantitatively, furthermore correlativity between fractal dimension and roughness coefficient ( jrc ) is analyzed
