Compared with the existing finite element eigenanalysis method[8]for asymptotic fields near the crack tip, current method has the following several characteristics: The jump-off that educes the virtue work formula is different; when solving the characteristic formula with FEM, the form of the element is non-confirming element; the singular transformation technique is not used in the assumption of displacement fields surrounding the wedge tip.

该方法与过去的有限元特征分析方法[8]相比的显著特点是：导出虚功原理的出发点不同；有限元单元形式为非协调元；楔形体端部邻域内的位移场假定没有采用奇异变换技术。

The 21st-century answer to this 18th-century riddle is that a species is what a taxonomist says it is.

21世纪的新技术对18世纪的谜语其实也没有那么大的帮助。决定一个物种的权力依然在物种分类学家手上。

After all, the problems of poverty and racism, the uninsured and the unemployed, are not simply technical problems in search of the perfect ten-point plan.

毕竟，贫穷和种族主义的问题，没有上保险和失业的人增多，这并不只是在实现完美的国家计划上技术方面的问题。

Australia had no commercial building projects of such scale in the 1970s and migrant labourers brought experience gained on large construction projects in Europe and a tradition of trade unionism and the construction site became a bastion of the Builder's Labourers Federation and the Communist Party of Australia.

在十九世纪70年代，澳大利亚还没有如此大规模的商业建筑工程，然而，移民劳工带来了从欧洲大型建筑工地学到的技术和经验，同时，他们也带来了工团主义的传统。因此，这一建筑工地成为了"建筑劳工同盟"和"澳大利亚共产党"的一个堡垒。

At present, there are many reports about the coupling of single laser and lens, and the technic also is quite mature. However, because of the precise requests of the manufacture technic and assembly, the technic of shaping for unidimensional linear and two-dimensional planar beams is not mature enough, almost at the researching or experimenting stage.

目前，关于单管激光器与透镜耦合的方式国内外报道很多，技术也比较成熟；但对激光束阵列的一维线阵和二维面阵整形，由于其制作工艺、耦合组装的精度要求很高，国内外还没有十分成熟的工艺，多处于研究实验阶段。

While United Devices tackled the complex security, scalability and unobtrusiveness issues required for a superior enterprise grid, neither our vision, nor our technology is limited to the realm of the PC.

当UD处理一个高级企业网格所需的复杂的安全性、可升级性和友好性等事项时，我们的想法我们的技术都没有受限于PC领域。

As the aeolotropism development of cracks in carbonate reservoir, so far not a very good seismic reservoir crosswise prediction method application for the aeolotropism carbonate reservoir, especially in the seismic, logging joint inversion, is mainly continues to use the reservoir crosswise prediction method that suitable for the isotropic clastic rock reservoir.

由于碳酸盐岩储层裂缝发育的非均质性，到目前为止还没有一套推广应用很好的针对碳酸盐岩非均质性储层进行地震储层横向预测的方法，尤其是在地震、测井联合反演方面，主要是沿用适合于较均质的碎屑岩储层地震横向预测技术。

The new GV preparation method we developed allowed the best visualization of chromatin distribution after Hoechst or CMA3 staining. Our results showed that GV chromatin configurations are different among different species, and thus, while chromatin condensed into a ring around the nucleolus in porcine and bovine oocytes, no such a ring was observed in caprine oocytes; Porcine oocytes were synchronized at GV1, goat oocytes at GV3n and bovine oocytes at GVf configurations before GVBD occurred, indicating that these configurations are progressive towards final maturation rather than atresia; Changes of chromatin configurations were associated with gene activity of transcription; GV chromatin configurations were affected by the environmental changes such as serum starvation and elevated temperature.

应用该技术对猪、山羊和牛不同大小、不同健康程度卵泡及体内和体外成熟过程中卵母细胞染色质构型的变化发现：1）不同动物卵母细胞染色质构型不同；猪和牛卵母细胞染色质围绕核仁凝集形成环，但山羊卵则没有此环。2）卵母细胞在GVBD之前都同步在某一染色质构型；猪同步在GV1，山羊GV3n，牛GVf，说明这些染色质构型代表着进行性变化。3）染色质构型的变化反映基因转录活动的变化。4）染色质构型受环境变化的影响。

The technology of culture of exogenetic NGF in vitro is qualified now, however, the exogenetic NGF cant get through blood-brain barrier and blood-nerve barrier because it is a kind of marcomolecular protein, thus its extensive application on clinic is limited, now, many scholors have turned their study direction to enhancing the content of endogenous NGF.

外源性NGF的体外合成技术已基本成熟，然而，外源性神经营养因子作为一种高分子蛋白物质不能通过消化道给药、不能通过血脑屏障和血神经屏障的问题阻碍了它在临床上的广泛应用，所以NGF在临床上并没有真正发挥出其营养神经的作用。

She left China when she was 5 and her memory of her homeland was very vague, but she didn't forget her own griefful life background---her parents died because of backward medical treatment, so she wanted to do her bits to change this situation.

她5岁时离开了中国，记忆中对祖国的印象非常模糊，但她却没有忘记自己的悲苦身世——父母双亲是因为医疗技术落后而被夺走生命的，无论如何也要为改变这种局面而尽到自己的责任。

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。
