本文在综合评价现有研究成果的基础上认为，岩石的成分变异和体积变化是韧性剪切带内流体作用研究的主要内容，韧性剪切带内构造-流体演化历史、构造物理化学、岩石应变模式及其特征的研究是今后韧性剪切带内流体作用研究的发展方向和前沿领域。

It is shown that adiabatic shearing fracture is main reason of resulting in the plugging occurrence. The residual adiabatic shear bands in the destroying process, which distribute reticulately from the surface of penetrated hole to internal area, is very wide. It is easy to result in falling of fragments....

冲塞的发生以绝热剪切破坏为主，靶板中残留的剪切带比较宽大，由弹孔表面向靶板内延伸，呈网状分布，易造成碎块的脱落，另外，绝热剪切带的形成与塑性力学静载下滑移线的形成密切相关，其走向与滑移线的方向基本一致

When OMMT content was below the percolation threshold, at small shear strain conditions, shear flow could enhance the crystallization of iPP, and the crystallizing entity was spherulitic.

OMMT在复合材料中的组分含量较低时，剪切场的施加能够明显地促进聚丙烯的成核与结晶生长，随着剪切应变的增加，由于剪切诱导作用，样品中形成串晶及取向的球晶结构。

In this way,after the viscosity or apparent viscosity of virgin crude,corresponding unsheared PPD-beneficiated crude and the sheared PPD-beneficiated crude at a certain temperature are determined,the parameters in the model can be calculated.

按照此方法，只须测定一定温度下空白原油的粘度或表观粘度、未剪切时加剂原油的粘度或表观粘度，及在某一个剪切温度下及某一个粘性流动熵产条件下原油的粘度或表观粘度，即可近似确定该数学模型中的参数，从而预测在不同温度时剪切后的原油在该温度下的粘度或表观粘度。

The relationship of slope and upslope drainage area of the study area is S = 0.074 A-0.1895, and the gully initiation process is an interaction process of hydrological erosion, melt erosion and landslide erosion, the initiation threshold is increased by the biomass.

研究所得的切沟发育临界地形条件为S = 0.074 A-0.1895，研究区切沟发育的过程是受水力侵蚀、冻融侵蚀和重力侵蚀的交互影响的过程，而沟头植被覆盖的增大会导致切沟发育临界条件的增大。

According to the relationship between the shear rate and the energy dissipation rate,a method for calculating the average shear rate based on the volumetrically average energy dissipation rate is presented.

根据能量耗散率与剪切率的关系，提出了按流体的体积平均能量耗散率计算流体平均剪切率的方法，即可根据流体的密度、平均流速、管道直径、流动的摩擦因子或摩阻压降以及流变参数计算牛顿流体和幂律流体管流的平均剪切率。

The results show that for a supersonic shear layer without reaction, a disturbance can make the shear layer become unstable, this results in one vortex or more than one vortex. The combination and seperation of vortex can intensify the mixing. But it is not easy for supersonic reacting shear layer with exotherm to become unstable with disturbance, and the effect duration is very long.

结果表明，对完全气体的超声速剪切层流动，一定的激励方式能使原先较为稳定的剪切层流动变得不稳定，产生单涡或多涡结构，发生多涡间的合并，使混合加剧；但对于存在放热现象的反应超声速剪切层流动，外加激励方式不易使流动从稳定变为不稳定，而且外加扰动的作用特征时间也较长，实际应用前景不乐观。

By comparing the pictures captured during cutting, we can see that chip breaker plays its role most in the planing cutting direction. The cut fibers are break by chip break before hand, so that digging out reduces.

从切削过程中采集的图片及切屑状态，并对照试验一的图片，可以看出在纵向切削时断屑器所起的作用最为明显，切屑在断屑器的作用下被提前折断，加工试件表面的挖切现象也比试验一中有所减少。

Full length LMP2A cDNA was firstly incised from pGEM-T-LMP2A with EcoR Ⅰ, Sma Ⅰ digestion, and then inserted into eucaryote. expression plasmid pCIcc controlled by CMV promoter. The CMV-LMP2A-SV40 expression unit was digested by ClaI, and inserted into E1-substituted adenovirus vector pAx1cw. Then the LMP2A recombinant adenovirus vector was cotransfected into 293 cells together with EcoT22I digested Ad5-TPC.

将带有LMP2A cDNA的重组质粒pGEM-T-LMP2A用EcoR Ⅰ、Sma Ⅰ双酶切下LMP2A cDNA，并将其插入含同样酶切位点的真核表达质粒pCIcc中，使其受控于CMV启动子下；用ClaI切下CMV-LMP2A-SV40表达单元，插入E1、E3区替代的腺病毒载体pAX1CW，选择正确的克隆pAX1CW-LMP2A与Ad5 DNA-末端肽复合体共转染293细胞，通过同源重组获得复制缺陷型的重组腺病毒(Ad5-LMP2A)。

"I have examined a file of each of the newspapers published in Chelmsford and Colchester," continued Robert, without replying to my lady's last observation, and I find in one of the Colchester papers, dated July the 2nd, 1857, a brief paragraph among numerous miscellaneous scraps of information copied from other newspapers, to the effect that a Mr. George Talboys, an English gentleman, had arrived at Sydney from the gold-fields, carrying with him nuggets and gold-dust to the amount of twenty thousand pounds, and that he had realised his property and sailed for Liverpool in the fast-sailing clipper Arqus.

&我曾查阅了分别在切尔姆斯福特和科尔切斯特出版的报纸的两份合订本，&罗伯特没理睬爵士夫人的最后那句话，迳自继续说下去，我在一八五七年七月二日出版的科尔切斯特报纸上看到：在许多从别的报上抄来的各式各样的短讯之中，有那么短短的一段新闻，大意说：有一位乔治·托尔博伊斯先生，一位英国绅士，从金矿地带到达悉尼，身边带着金块和金砂，价值达两万英镑，他已将金块等兑换成现款，乘坐快速班船'百眼巨神号'前往利物浦。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
