The results showed that the displacement of the surrounding rock of cavern evidently decreases with the increase of in - situ stress side pressure coefficient , as well as the decreasing rate of surrounding rock displacement of cavern with increasing at the condition of < 1 are significant larger than that of > 1 ; when < 1 , the displacements of measured points in cavern increase then decrease with the increasing incident angle of shear wave , while , when > 1 , the displacements decrease then increase with the increasing incident angle of shear wave , and the influence of incident angle on the displacements of measured points tends to decrease with the increasing in - situ stress side pressure coefficient 分析结果表明，地震荷载作用下，硐室位移随地应力侧压系数的增加明显减小，地应力侧压系数< 1时的硐室位移量值随侧压系数的变化幅度明显大于地应力侧压系数> 1时的情况；当侧压系数< 1 ，随剪切波入射角的变化，硐室测量点位移响应先增加后减小；而当侧压系数> 1 ，随剪切波入射角的增加，硐室测点位移先减小后增加，同时随地应力侧压系数的增加有减小的趋势。
The corresponding incident angle of the peak is called interference - spr angle , int - spr - the similar linear relationship betweenint - spr and the depth of bio - sensitive film , the refractive index of bio - sensitive film respectively compared with the resonant angle ospr . it shows that it is able to use interference - spr angle , int . spr as a indicator to monitor v ery s mall c hanges i n b iochemical s amples i nstead o f the r esonant a ngle four intelligentized spr instruments have been developed successfully 干涉谐振角_ ( inl - spr )在厚度d _ 3或者折射率n _ 3分别变化时，与变化的参量( d _ 3或n _ 3 )有着良好的线性关系，与spr谐振角_ ( spr )的线性具有相同的量级，这说明有可能通过测定干涉谐振角_ ( inl - spr )来检测生物样品的细微变化，从而提出了一种确定spr峰值移动的全新的方法。
For parameter a , there is a close relationship exist between a ( 9 , sr ) in two different radar incident angle that can be expressed as : with considering the effects of soil texture , we get the final expression of the inversion model : where mv ( t1 ) , mv ( t2 ) is volumetric soil moisture content in two different temp , c , d is soil type related parameters , and v ( t1 ) , s ( t2 ) is coresponding bare soil radar backscattering coefficients . inversion results show that for the c band hh polarized radarsat scansar data with a range of incidence angle from 20 to 40 , the soil moisture change value can be derived with an acceptable accuracy using the above model . the temporal and spatial soil moisture change patterns are associated with rainfall and vegetation cover , as well as the soil hydraulic characteristics 利用最新发展的电磁波散射模型研究了不同植被覆盖地表雷达波对地表土壤水分的敏感性，建立了半经验植被雷达后向散射模型; 2 ) .研究发现在农作物等矮小植被覆盖地表，植被层直接后向散射与植被类型相关，且在植被生长期，雷达后向散射系数对植被含水量的敏感性要高于对植被高度变化的敏感性; 3 ) .解决了单参数雷达地表土壤水分反演问题中，雷达入射角和地表粗糙度的影响这一难点问题; 4 ) .利用土壤介电模型校正了不同土壤类型对反演地表土壤体积含水量的影响; 5 ) .在以上成果基础上，建立了完整的单参数雷达地表土壤水分变化探测反演算法，经地表验证，模型反演地表土壤水分变化值的精度为rmse = 0
By employing the theory of operator representation , the reflection / transmission operator is decomposed into the form of double domains in the scheme , so it is adaptable to laterally heterogeneous media and fluctuating reflectors , can mimic ava of reflections when the incident angle is less than 45 文中利用算子可分表示理论将反射透射算子分解成适合于双域（空间域和波数域）运算的表达形式，使得本文得到的地震波数值模拟算法可适应于一定程度横向非均匀介质和界面起伏情况，在入射角小于45时能够准确模拟振幅随入射角( ava )的关系。
When the frequency approaches zero , the factor approaches zero correspondingly ; 2 ) the amplitude of interaction factors changes with the incident angle of rayleigh waves and reaches maximum when is zero . moreover , with the increase of , the wave period shortens apparently ; ( 3 ) the amplitude of interaction factors decreases as the pile spacing increases and approaches to zero when the pile spacing is 15 ; 4 ) the amplitudes of interaction factors increase clearly with the increasing stiffness ratio of pile to soil ; 5 ) the lat eral seismic response of fixed - head pile groups is much smaller than that of free - head pile groups . moreover , the pile - group effects induced by rayleigh waves can be neglected ; 6 ) the lateral seismic response of piles at different location differs from each other 得到了以下结论： 1 )桩的相互作用因子随频率呈周期性变化，在振动频率比较低的情况下，桩的横向相互作用因子也较低，当频率趋近于零时，相互作用因子也趋近于零； 2 )桩的相互作用因子的幅值随瑞利波入射角度的变化而变化，在= 0情况下幅值最大，且随入射角度的增加，波动的周期明显缩短； 3 )桩的相互作用因子的幅值随着桩与桩间距的增加而减小，至s d = 15时，桩的相互作用因子基本趋近于0 ； 4 )在频率比较低时，相互作用因子幅值随桩土相对刚度比的增加而显著增加； 5 )桩顶固接可以有效地降低群桩的横向地震响应幅值，由瑞利波产生的群桩效应可以忽略不计； 6 )群桩中不同桩位的桩的横向地震响应是不同的，每根桩所在的桩位对其横向地震响应有很大的影响；刀桩数的增加并不能减小桩的横向动力响应。
Due to the different values of incident angle , there are two different propagation formats . one case is that the beam is finally trapped in a guide - like channel and propagates stably along the channel when the launching angle is smaller than a critical value . otherwise , it will propagate along the incident direction all along 由于入射角度的取值不同,格子孤子具有两种不同的传输方式:当光束入射角小于某临界角度时,光束可被类似波导形式的路径俘获,转而沿该路径向前传输;当光束入射角大于该临界角时,孤子则不会被俘获,而是沿着光束的入射方向直线传输。
The first one is the illumination design , through the simulation of solder surfaces , suitable illumination method could be induced by observing the synthetic images , and finally the adoption of a single - layer circular illumination with incident angle about 25 is concluded as the best illumination for extracting characteristic features from the images 首先是焊点检验的照明设计，利用焊点模型所合成的影像，以快速归纳出最适于焊点检验的照明方法，并在最后提出以入射角约为25的单层环形光源作为照明形式。
It is show that the initial power and the incident angle of the beam are important factors of formation and stable propagation of soliton . when the initial power matches with the beam width , a balance of diffraction and nonlinearity effects in propagation will be maintained and therefore the stable nonlinear lattice soliton comes into being 研究发现:光束的初始功率和入射角度是格子孤子形成和稳定传输的重要因素,当光束的初始功率与光束宽度满足一定条件时,可以维持传输过程中衍射和非线性效应的精确平衡,从而形成稳定的三阶非线性格子孤子。
