Then the azimuthally phase and group velocity formulas of plane wave propagation in horizontal plane are deduced according to Christoffel equation, and the azimuthally dependent velocities in dry and water saturated cracked medium are calculated.

而后，根据Christoffel方程推导了由各向同性背景介质中含两组非正交的垂直裂隙而形成的等效单斜各向异性介质中，在水平面内随方位变化的相速度和群速度的计算公式，并对干裂隙和饱和流体填充裂隙介质两种具体情况进行了计算。

We extend the second order elastic tensor of Husdon's and turn it to a matrix which makes the calculation of second order perturbation much more concise. Then the azimuthally phase and group velocity formulas of plane wave propagation in horizontal plane are deduced according to Christoffel equation, and the azimuthally dependent velocities in dry and water saturated cracked medium are calculated.

而后，根据Christoffel方程推导了由各向同性背景介质中含两组非正交的垂直裂隙而形成的等效单斜各向异性介质中，在水平面内随方位变化的相速度和群速度的计算公式，并对干裂隙和饱和流体填充裂隙介质两种具体情况进行了计算。

The study has also shown that there is a rotation angle for azimuthally NMO velocity ellipses in monoclinic media which different form HTI and orthorhombic media. The rotation angles of NMO ellipses are related to the property of fracture infill, fracture density ratio and the angle between the two fractures.

同时，研究表明对于裂隙型单斜各向异性介质，其方位NMO速度椭圆轴向并不象HTI介质和正交介质中的那样与自然坐标系的坐标轴一致，而是发生了一定角度的偏离，其大小与裂隙填充物的性质、两组裂隙密度的比值及裂隙间的夹角等因素有关，研究结果为进一步区分裂隙介质的类型及裂隙填充物的性质提供依据。

As the basis of inversion, we have summarized the overall expressions for Thomsen's parameters and their physical meanings, deduced the expressions of azimuthally varying NMO velocity that usually specifies an ellipse in the horizontal plane for any arbitrary anisotropy, and derived the expressions for the NMO ellipses described by Thomsen's parameters.

Complete horizontalization of the occlusal plane was achieved in five patients, whereas a cant of 1-4 degrees persisted in six patient.

结果：11例患者均顺利完成治疗，游离皮瓣均获得成功，所有患者面部偏斜畸形及咬合关系得到明显改善，5例患者咬合平面完全摆正，仍有6例患者咬合平面角维持在1°－4°。

Imitational precision is good, which demonstrate that Visual Structure Expert Systemcan be used to imitate cable-stayed bridge construction control, under the condition that forward-calculation is used and girder cell is used to imitate the cable cell, which is capable of acquire better control precision.

The clinical features including chief complaints, sex distribution, age at first visit, laterality, type of presentation, ocular deviation in the primary position, refractive errors, amblyopia, globe retraction, change of the palpebral fissure, upshoot and downshoot in adduction, binocular single vision, and its associated ocular and non-ocular anomalies were analyzed.

自1979～1996年回顾性地总结了201例DRS，对它的临床特征，包括主诉、性别分布、初诊年龄、侧向状态、表现类型、原在位的眼位偏斜、屈光不正、弱视、眼球后退、睑裂改变、内转时眼球急速上转和下转、双眼单视及其伴随的眼部和非眼部异常等予以分析。

This investigation shows that exotropia was found more frequently in distance lateral phoria in myopes. Stereopsis acuity negatively correlated with the degree of my-opia and subjects with a lower stereopsis acuity had a higher degree of myopia. There was no significant correlation between distance lateral phoria and stereopsis acuity.

本组近视眼视远时水平隐斜视中，外斜偏多；立体视锐度与近视屈光度呈正相关，立体视锐度较差者多分布于近视眼度数较大患者中；近视眼人群中视远时水平隐斜视和立体视锐度无显著相关。
