ESWL is not recommended as a singular ther-apeutic method for complete deerhorn-like nephrolith because of its long therapeutic course,high cost and easily be infect-ed.

因ESWL疗程长，易发生泌尿系统继发感染，完全鹿角形结石不宜单独采用ESWL治疗。

青春期内分泌系统机能变化显著，植物神经系统机能也不稳定，故情感较脆弱，容易发生神经衰弱、癔症及反应性精神病；情感性精神障碍和精神分裂症也多在此期发病。

It is now well accepted that super-activation of neuroendocrine system contributes to the pathogenesis of chronic heart failure.

近二十年来的研究工作强调在慢性心力衰竭的发生机制中神经内分泌系统过度激活起着十分重要的作用。

One of the mutant zebra fish has a reduced number of hair cells in neuromast of its lateral line system.

某一突变种斑马鱼，其测线系统中神经瘤上的毛细胞大量减少，下列何者将会发生

The results of numerical experiments, using the four-dimensional variational data assimilation system of the nonhydrostatic mesoscale model MM5, show that: the tangent linear model and adjoint model conducted by keeping the "on-off" switches the same as the basic state, can provide a good approximation of the first-order information to the NLM perturbation and a good descent direction for the minimization procedure; switching on and off at every other time step in the Kuo cumulus parameterization scheme don"t impact the convergence rate of cost function; the existence of the switches don"t impact improvement to the MM5 model rainfall prediction because that not only specific humidity ,but also wind, temperature and pressure are assimilated into the model.

非静力中尺度数值模式MM5的四维变分资料同化系统进行的数值试验结果表明："开关"变量保持与基态一致，所构造的切向线性模式能够提供关于非线性模式扰动的一阶近似，伴随模式所计算的梯度值能够为最小化过程提供较好的下降方向；郭氏降水参数化方案中对流每隔一个积分步的交替发生并不影响目标函数最小化的收敛速度；"开关"变量的存在也不影响将风、温度、气压和比湿结合起来同化对MM5降水预报准确性的提高。

However, it is necessary for us design an architecture which allows subsystems to be merged into an integrated node computer in order to save cost. At the same time, it must be ensured that residual design faults in low criticality subsystem cannot corrupt high criticality subsystem while they cooperate with each other.

为设计高可信的任务关键实时操作系统，探索了基于时间隔离与空间隔离保护机制构建高可信任务关键实时操作系统的新思想，其目的是把设计缺陷所导致的失效影响控制在一个较小的时空范围内，使实时操作系统在其支撑范围内提供尽可能强的可信防范机制，在用户应用程序与系统资源之间进行符合防危策略的调度，防止发生灾难性事故。

The nonparametric statistic method was also used to systematically analyze the soil physiochemical properties and the environmental risk of birth defects,combined with analysis.

为研究土壤性质在出生缺陷环境风险中的指示作用，考虑了区域人口分布和疾病空间结构，使用Bayesian方法，对山西省和顺县连续4年的神经管畸形发生的数据进行了处理，并使用非参数统计的方法，结合土壤环境过程机理，对土壤的理化性质和出生缺陷的环境风险做了系统分析。

This strategy has put Cisco on a collision course with heavyweights Lucent Technologies and Northern Telecom.

这项举措使CISCO系统公司与朗讯科技公司和北方电信发生了严重的冲突。

Heavyweights Lucent Technologies and Northern Telecom.

Producing of onset of nucleate boiling with subcooled boiling is early at same condition.

研究结果表明：自然循环欠热沸腾起始点的热力学平衡干度对加热量、进口温度、系统压力有着更大的敏感特性，在同等条件下，更早发生欠热沸腾现象。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。

The relationship between communicative competence and grammar teaching should be that of the ends and the means.

交际能力和语法的关系应该是目标与途径的关系。
