Requests on resistance of corrosion destructibility of sealing interfaces that related to sealing up and cementing exercises in petroleum engineering are more and more of rigidity. It is urgently needs to resolve all sorts of problems that affect interface bonding quality. Conventional cement slurry design resist the destructive function worse, and can't like to satisfy the request to carry on latter production such as perforation, acidify, fracture etc.

常规油井水泥抵抗破坏的性能较差，不能很好满足水泥环抗冲击振动以及射孔、压裂等各种变形破坏的要求，这在一定程度上限制了小间隙、大位移、定向与水平井等特殊钻井工艺技术的发展，也制约了后期压裂、酸化等诸多开发工艺措施的实施。

This property is why it is a valued base for paints and varnishes, but this varnish is chemically closely related to the age pigment that forms "liver spots" on the skin, and similar lesions in the brain, heart, blood vessels, lenses of the eyes, etc. The image of "hard, white saturated coconut oil" isn't relevant to the oil's biological action, but the image of "sticky varnish-like easily oxidized unsaturated seed oils" is highly relevant to their toxicity.

这个属性是为什么它是一个有价值的基地，涂料，油漆，清漆，但这个是化学密切相关，年龄色素的形式"肝点"，对皮肤，和类似的病变，在脑，心，血管，镜头的眼睛等的形象，"硬，白饱和的椰子油"是不相关的石油的生物行动，但形象"粘研磨剂一样容易氧化的不饱和籽油"是高度相关的毒性。

The results of numerical simulation reveal that the resistance to liquefaction of sands increases as the angularity of particles increased, and the micro_mechanism is related to the average coordination number of sample. It also found that the numerical sand sample made from randomly mixing multiple shapes of sand can quantitatively reflect the regularity of fabric evolution of sands during liquefaction.

结果表明，颗粒棱角度越大，试样抗液化能力越强，其在细观机理上与初始平均接触数大小有关；随机混合仿真试样可以从定性角度反映实际砂土振动液化过程中的细观组构演化规律，为今后进一步的定量研究奠定了基础。

The results indicate that its dynamic stress-strain curve is hyperbolic type. The dynamic strain of LCES decreases with increasing confining pressure, cement content, curing ages and cyclic loading frequency when it is subjected to the same dynamic stress. At the same dynamic strain, the dynamic secant elastic modulus E_(sec of LCES increases and the damping ratio decreases with increasing confining pressure, cement content, curing ages and cyclic loading frequency. The curves ofσ_d～ε_d,E_～ε_d and D～ε_d with different EPS content intersect respectively, the trend of LCES deformation characteristic is inversely proportional to EPS content near the intersection. The value of dynamic strain at the intersection is about 0.5%~3.0%, the magnitude of which is related to the mixing proportions and confining pressure.

试验结果表明，LCES的动应力应变骨干曲线形态符合双曲线；在相同的动应力作用下，LCES产生的动应变随着固结压力、水泥掺量、试样养护龄期和振动频率的增大而减小；在动应变相同的情况下，随着固结压力、水泥掺量、试样养护龄期和振动频率的增大，LCES的动模量增大而阻尼比减小；随着加载次数的增大，LCES的动模量在开始阶段显著降低，然后趋于稳定，但当加载次数达到几百次时，动模量又有增大的趋势；不同EPS掺入比的LCES的动应力应变骨干曲线、动模量随应变变化曲线和阻尼比随应变变化曲线都发生了相交，交点前后EPS掺入比的大小对LCES动力变形特性的影响趋势是截然相反的，交点处的动应变值一般在0.5％～3.0％范围内变化，其大小与LCES的配比以及固结压力有关。

国际航运中心的建设除了提供先进的硬件设施以外，优质、高效、安全的软环境也是国际航运中心必须具备的条件，而良好的水上交通安全秩序是国际航运中心建设软环境中一个极其重要的条件，为适应上海国际航运中心的建设，口岸单位象海关、边防等单位相继投入大量的人力物力建设与国际航运中心相配套的软环境设施，与此同时，对作为上海港水上交通安全监督管理主管机关的上海海事局的航政管理、航海保障工作提出了新的要求，为适应快速发展的上海国际航运中心的建设，研究开发和建设实施航政管理、航海保障任务主要手段的高性能和高技术含量的巡逻船舶在当前显得十分迫切。

It is most likely that only a part of the karst caves could be detected if the boundary of the karsts cave has a certain horizontal extension respectively to measurement layout, but the interface of the karsts caves is not completely smooth plane, and its normal direction is not perpendicular to the tunnel axis. However, the precision of the cave detection is related to interface wave impedance difference of the karst caves, groundwater detection, operator's data acquisition experience and data processing level and so on.

如果溶洞的边界相对于TSP测量布线有一定的横向延伸性，其边界面不一定是完全平滑的表面，但其法线方向与隧道轴线不完全垂直，这类溶洞有可能被部分探测，但探测精度还与溶洞界面两侧的波阻抗差、对地下水的探测、操作人员的数据采集经验和数据处理水平等有关。

Chapter Two illustrates the nature of the international guarantee.At first,the writer analyses the meaning of collateral nature and its theoretical basis.Thewriter points out that in order to reinforce the protection of the guarantor'sinterest,the guarantee is located as collateral guarantee in all countries'traditional legislation.In other words,the validity of the guarantee contract isdetermined by the underlying contract,i.e.if the underlying contract isestablished,the guarantee contract is established,too;if the underlying contract isvalid,and the guarantee contract is valid too.It is true,otherwise.But thedoctrine of autonomy of private law dominates the civil law and commercial lawin all the countries,so the parties are permitted to alter the collateral nature of theguarantee by an agreement under the related laws worldwide.so the collateralnature of the guarantee is not the compulsory nature of the law.This lays a solidfoundation for the emerging of the independent guarantee.The writer thenanalyses the meaning of independence and the cause of the booming of theindependent guarantee.In fact,the independent guarantee was originated fromthe change of the collateral nature by the parties contract.As a result,the validityof the contract of independent guarantee is not determined by the underlyingcontract as the collateral guarantee,But the validity of the independent guaranteecontract is independent from the underlying contract,the establishment and thevalidity of the contract of independent guarantee are not subjected to theunderlying contract.

第二章对国际信用担保的法律属性进行了论述，首先分析了从属性的含义及其理论基础，指出虽然各国传统立法为了加强对保证人利益的保护，都将信用担保定位于从属保证，即保证合同的效力取决于主合同的效力，主合同成立，保证合同也成立，主合同生效，保证合同也生效；主合同不成立，保证合同也不成立，主合同不生效，保证合同也不生效，但是由于私法自治的精神主导着各国的民商法领域，各国立法都允许当事人通过合同约定对信用担保的从属性进行改变，所以保证的从属性从来就不是信用担保制度的法律强制属性，这也为独立保证制度的出现奠定了制度前提；其次分析了独立性的含义以及独立保证兴起的原因，独立保证实际上就是当事人通过合同约定对保证从属性的改变，使独立保证合同的效力不再象从属保证合同的效力那样取决于主合同的效力，而是使独立保证合同的效力独立于主合同的效力，独立保证合同成立不因主合同的不成立而受影响，也不因主合同的无效而无效。

It is also found the rest position of tongue is highly positive related to the magnitude of phase Ⅱa and phase Ⅲa. It demonstrated that anterior teeth retraction would not affect tongue movement during swallowing.

结果显示，在矫正治疗完成前牙后退之后，舌头吞咽各分期的持续时间与振幅皆没有改变；因此可证明，舌头本身对矫正治疗后牙弓型态及齿列空间的变化，具有相当程度的适应能力。

Moreover, strong anisotropy is observed in the north and southcentral Tien Shan. Fast Pn velocity in the southcentral Tien Shan is nearly in NS directions, which is consistent with the SKS wave anisotropy concerning mantle flow. However, fast Pn velocity directions in the northcentral Tien Shan show a southward rotation variation. We estimate that it is probably related to the inserting of the crust of the Chu basin from the southern Kazakhstan platform to the central Tien Shan, which caused a change of stress fields and lithosphere deformation.

中天山北部和南部的各向异性也存在一定的差异，南部各向异性的快波方向为近南北方向，与SKS波的各向异性特征基本一致，反映了地幔物质的迁移方向；北部各向异性的快波方向呈向南凸出的旋转趋势，估计与哈萨克地台南缘楚河盆地地壳块体向天山挤入造成应力场的改变和岩石层变形有关。
