在上游

This suggests that under average seismic loadings, we cannot avoid cracking in the upstream face.

这表明在平均地震载荷，我们无法避免开裂上游的脸。

To achieve the aim of water quality programming in the year of 2010 in the upper Suzhou creek, the CODcr cut amount of 2593 tuns will be deducted per year in runoff load , of which the village and rice field load cut amount per year were larger than others, however, the cut amount of village and town for a grid was high in the upper valley of Suzhou creek, the total cut amount in fish ponds per year was not too high, but the cut amount for grid was high.

但无论在苏州河的上游和中下游，均以村和镇的单位网格削减量为最高，精养鱼塘虽然年削减量不高，但单位网格削减量却较高。

To measure the differential pressure when the fluid is flowing, connections are made from the upstream and downstream pressure tappings, to a secondary device known as a DP cell.

为了测量时的压差，流体流过，连接了从上游和下游的压力窃听，在二次设备作为民主党细胞。

Main advances of research on vortices in pump sumps;2. Based on flow field analysis,it shows that owing to the wakes behind the upstream suction pipe,the downstream flow becomes more turbulent and appears with obvious free-surface vortices and submerged vortices in complicated movement.

本文在玻璃水槽内对不同管间距条件下的吸水管周围进行了大量的PIV流场量测实验，通过流场分析显示，上游吸水管的尾流作用加剧了下游吸水口的水流紊动强度，流场多处出现表面旋涡和水内旋涡，其运动形态复杂多变。

The predicted amino acids are indicated by one-letter code designations below the nucleotide sequence.

BusuNPV p47基因的起始密码子上游第16位有一杆状病毒早期基因转录起始信号CAGT［12］，在-100位和-120位有两个早期启动子组成元件TATA。

In this situation, such long-negotiated instrument of international water law as the 1997 UN Convention on the Non-Navigational Uses of International Watercourses, is of little help as it provides for equally contradictory 'equitable use' and 'no significant harm' principles: while the former is favoured by upstream countries, downstrea m riparians insist on emphasising the latter because it protects their own rights.

在这种情况下，经过多次谈判而形成的1997年《联合国关于国际水道非航行使用法》并没有多大帮助，因为它同时采用了自相矛盾的&公平地使用&和&无重大损害&原则。而上游国家喜欢前者，下游国家更钟情后者，因为它保护自己的权益。

To reveal aft end internal flow feature of a solid rocket motor with submerged nozzle, a two dimension cold flow test model with rectangular channel was designed The cold gas simulation was based on geometric similarity and aerodynamic analogy Mean and fluctuating velocity field was measured using phase doppler particle analyzer It showed that the flow separates at upstream of the submerged nozzle and reattaches on the tip of the nozzle nose A relatively steady recirculation zone formed in...

为了揭示含潜入喷管的固体火箭发动机尾部流动特征，按照几何相近和气动相似原则设计了通道为矩形的二维冷流实验模型，利用相位多普勒粒子分析仪对燃烧室尾部气流的时均速度和湍流脉动速度进行了测量。实验结果表明气流在潜入喷管入口上游发生分离，再附点位于喷管前端部外侧，背壁空腔内形成一个较为稳定的回流区，流场的轴向和横向湍流强度都比较大

Of course there was a booming current; and of course that boat started her engines again ten seconds after she stopped them, for they never cared much for raftsmen; so now she was churning along up the river, out of sight in the thick weather, though I could hear her.

当然 啰，水流得很急。轮船停机以后十秒钟，又开动了机器。因为这些轮船根本没有把木筏子上的工人放在眼里，眼下它正沿着大河往上游开过去，在浓重的夜色中消失得无影无踪，只是偶尔我还能听到它的声音。

In this study, to define the functional roles and mode of the upstream regulatory elements ofα-globin gene cluster,αMⅡwas obtained, in which the 31.7kb sequence including HS-33, HS-10、HS-8 and HS-4 was deleted by defective prophage mediated by the homologous recombination;αMⅢwas also constructed, in which the 35.4kb sequence including HS-40、HS-33、HS-10、HS-8 and HS-4 was deleted by the method of temperature sensitive shuttle vector mediated homologous recombination.

在此基础上，为了定义α-珠蛋白基因簇上游各调控元件的调控功能，并探讨其作用机制，本研究利用缺陷型原噬菌体介导的同源重组法修饰α-BAC，删除包括HS-33、HS-10、HS-8和HS-4在内长达31.7kb的序列得到BAC突变体αMⅡ；又利用温度敏感型的穿梭载体介导的同源重组法删除包括HS-40、HS-33、HS-10、HS-8和HS-4在内达35.4kb的序列，得到BAC突变体αMⅢ。

In the negative and interrogative forms, of course, this is identical to the non-emphatic forms.

。但是，在否定句或疑问句里，这种带有"do"的方法表达的效果却没有什么强调的意思。

Go down on one's knees;kneel down

屈膝跪下。。。下跪祈祷
