Angular spectral is spectral value map formed by estimating semblable coefficients of fast and slow shear wave or the variation of amplitude ratio of fast and slow shear wave with times and angles at a specified space point based on semblable theory of fast and slow shear wave, the angle value of this space point at a given time can be got by picking the maximum of angular spectral; the study reveals that fast and slow shear wave with different polarization direction should be separated using different rotation formula, eight formulas of separating fast and slow shear wave using clockwise rotation and counterclockwise rotation have been derived, and gained energy assignment rule and phase coincidence rule, in real data estimation, the rotation formula used for separating fast and slow shear wave can be uniquely determined on the two discriminating rules. On the basis of semblable theory of fast and slow shear wave, the delay time corresponding to the maximum of semblable coefficients at a specified point in a given time window is the delay time of fast and slow shear wave, delay time section of fast and slow shear wave can be got by moving space point and smoothing time window. The vertical variation values of delay time of fast and slow shear wave reflect the effect degree of vertical fractured reservoir on fast and slow shear wave which is defined as anisotropic coefficient, and section map of anisotropic coefficient can be obtained.
角度谱就是利用快慢横波的相似性原理,在某一空间点求出快慢横波的相似系数或快慢横波的振幅比值随着时间和角度的变化而形成的谱值图,拾取其极大值就得到该空间点某一时间的角度值;在研究中发现分离不同偏振方向的快慢横波应该采用不同的旋转公式,推导出了利用顺时针旋转和逆时针旋转分离快慢横波的八个公式,并给出了能量分配准则和相位一致性准则两个判别准则,在实际计算中利用这两个判别准则能唯一地确定分离快慢横波的旋转公式;根据快慢横波的相似性原理,在某一给定点和给定时窗内最大相似系数对应的延迟时间就是快慢横波的延迟时间,随着空间点的移动和时窗的滑动就可以得到快慢横波延迟时间的剖面图;快慢横波延迟时间与慢横波传播时间的比值定义为裂缝密度,并求出了裂缝密度剖面图;快慢横波延迟时间纵向上的变化值的大小反映了纵向上裂隙层对快慢横波影响的大小,定义为各向异性系数,并求出了各向异性系数的剖面图。

The results of 3-D numerical modeling of the transversely isotropic media with horizontal symmetry axis and the orthorhombic symmetry media showed that quasi P wave,quasi-SV wave and quasi-SH wave occurred during elastic wave propagation in 3-D anisotropic media. Meanwhile, the special phenomena such as the S wave splitting, the blind zone of S wave splitting and quasi-SV wave-front triplication were clearly observed. In addition, the elastic wave-fronts are spatially changed, and the coupled relations among the quasi-P wave,quasi-SV wave and quasiSH wave in 3-D anisotropic media are very complex.
对方位各向异性介质模型和正交各向异性介质模型中弹性波的传播进行的三维数值模拟结果表明,弹性波在三维各向异性介质中传播时存在拟P波、拟SV波和拟SH波,并出现横波分裂、横波分裂盲区、波面三分叉等特殊现象,另外,性波场在空间是变化的,其拟P波、拟SV波和拟SH波的耦合关系比较复杂。

Asian citrus psyllids and in the Citrus Aphis citricola both the phloem feeding insects, but insect feeding behavior of two significant differences, in addition to two kinds of insects share a common EPG wave (A wave, B wave, C wave, E1 wave, E2 wave, G wave), the wave of Aphis citricola appeared in the path of many pd wave, pd wave is aphids in plant cells in the epidermis during exploratory puncture the cell membrane caused by feeding, which kind of contact information on the intracellular selection in the aphid host plant play an important role in the process.
求中文翻英文翻译,很急,谢谢亚洲柑桔木虱和绣线菊蚜在沙田柚上都为韧皮部取食性昆虫,然而,两种昆虫的取食行为有明显差异,除了两种昆虫拥有共同的EPG波形(A波、B波、C波、E1波、E2波、G波)外,绣线菊蚜在路径波中出现很多pd波,pd 波是蚜虫在植物表皮层细胞的试探性取食时刺破细胞膜而产生的,这种对胞内信息的接触在蚜虫选择宿主植物的过程中起了重要作用。

cold wave:寒潮
例如晚秋和冬季时节,由于北方冷空气和寒潮(cold wave)不断南侵,峰面活动十分频繁(气象要素或其泛导泛极的泛导=*0/0,1/0),这样就很容易导致高血压、冠心病、克山病等等心血管病发作.
