The monotonic and cyclic shear tests of the interface between geotextile and gravel as well as geotextile drawing tests were conducted with the apparatus. The interface was found to exhibit strain-softening and obvious aeolotropic normal displacement which was affected by the normal stress.

剪切试验结果表明，粗粒土与土工布接触面出现了一定程度的应变软化，相对法向位移的变化受法向应力影响很大，并表现出异向性。

Thirty-six patients had radiographic evidence of femoroacetabular impingement at the time of revision. Revision procedures included 34 (95%) for femoroacetabular impingement, 32 (87%) for labral lesions, 26 (70%) for a chondral defect, 23 (62%) for lysis of adhesions, and 13 (35%) for previously unaddressed instability.

翻修术时发现有36例患者在股骨头髋臼接触面存在侵犯，关节唇损害32(87%)例，关节软骨缺损26 (70%)例，需要粘连松解术的23 (62%)例，以前关节存在不稳定因素的有13 (35%)例。

The characteristic of traffic company is flow disperses, interface is wide, the relation is daedal.

交通企业的特点是流动分散，接触面广，关系错综复杂。

The core of this model is using solid element to simulate elastoplasticity deformation of faultage and using contact element to simulate the interface of faultage and rock, and so, realizing the problems coupling of elastoplasticity and contact.

模型的核心是以三维实体单元模拟断层或软弱夹层材料弹塑性变形特性，以接触面单元模拟断层或软弱夹层与完整岩石之间交界面的力学特性，即剪切效应和法向提离效应，从而实现了弹塑性问题和接触问题的耦合。

This is due to the dry friction damping is merely limited to shroud interface and is a standard local nonlinear problem, when directly solving it, most operations will be used meaninglessly to regenerate its linear elements except for modifications of some elements of stiffiness matrix and damping matrix.

这是由于干摩擦阻尼只局限于凸肩接触面，是典型的局部非线性问题。直接迭代求解时，除了只需对系统刚度矩阵、阻尼矩阵的个别元素进行修正外，有相当一部分运算毫无意义地用于线性元素的重新生成上。

Nevertheless, in these aPproaches the contact intethee are charactered sboly edstiffeess K. and K.' which is not PerfeCt and rigorous in thc vitw of solidmechanics and rather rough for the description of the behavior of the iDtfores. Incollbet, taken as a contact Problem, the principal chatrs of the iDtCthees can bereflected: the cbntact inifore is of shear strength Which imPlies tha a genericpair of contact points on the inidse will displace coincidentally if the tangentialfbrce at this POint has not reahed the 1imit resistance, else, relative s1ide betwee the\ points will occur along the tangental direction.

本论文在对这两种方法进行认真的分析后，说明它们对不连续面的描述并不合理，也无法反映出不连续面的主要力学特性，同时指出，将带有不连续面的岩土工程问题作为接触问题计算更为合理，它可将不连续面受力变形的主要特点反映出来，即：(1)接触面具有相应的&抗剪强度&，即当接触面上某一点处的切向应力小于该点处的抵抗强度时，点对共同变形；达到强度时，则沿切向发生相对滑动；(2)在整个变形过程中，发生接触的变形体不能相互侵入。

Through the impeller's spinning, produce water leap, form water film and spray, have a big air-contact surface and bigger aerating action.

通过叶轮的旋转，产生水跃，形成水膜及水花，与空气接触面大，有较大的曝气作用。

Cynanchum Lingtai apricot production in the average weight 65 grams, the brightly-colored fruit, juicy rich, sweet-sour taste, sweet from the nucleolus, when the late Qing Dynasty famous Shaanxi, Gansu provinces, the Qing imperial court Tongzhi tribute for years.

灵台生产的牛心杏平均单果重65克，果实色泽鲜艳，汁多味浓，甜酸适口，离核仁甜，清末时就驰名陕、甘两省，清同治年间曾为朝廷贡品。

Chenopodium album,Solanum nigrum, and Amaranthus retroflexus were very susceptible to the herbicides. Polygonum persicaria and Abutilon theophrasti were relatively less susceptible to the herbicides, and Lycopersicon esculentum was not susceptible to it. The relationship between reduction rates of weed biomass and PPM values of weed leaves 2,4, and 6 days after treatment was established.

供试的6种杂草对该混剂的敏感性存在显著差异：红心藜Chenopodium album、龙葵Solanum nigrum和反枝苋Amaranthus retroflexus对该混剂最敏感，ED90值分别为47.65、71.67和29.17g/hm2；春蓼Polygonum persicaria和苘麻Abutilon theophrasti敏感，ED90值分别为96.91、114.20g/hm2；而番茄不敏感。
