上游

Over the past 5-years, more than 1,100 vessels moved upbound on average.

过去五年来，每年向上游行驶的船舶数量平均在1100艘以上。

Military officials said troops landed in the remote Perchard area in the upreach of Valley that have been under Taliban control.

军方称空降兵在Piochar 地区的山谷上游降落，该地是塔利班控制地。

The premises of the simulation are that the runoff from upreach is 7.8× 108m3/a and the means of economization on water is in effect. When studied it was thought firstly the water for the lake area and the living plant of the oasis, then for forest-sod irrigation and farmland irrigation.

模拟计算是以上游下泄水量7.8×10~8m~3／a为前提条件，在实行节水措施，完善供水系统的情况下，首先满足维持和恢复一定规模湖泊面积，保证绿洲植被正常生长所需水量，然后考虑林草灌溉用水和农田灌溉用水量。

The theory and basic assumption of distributed hydrological for water resources assessment under various environment is introduced to solve the problems of restoration distortion and restoration invalidation in traditional method. A method, namely UCMV (upreach for calibration and mid-reach for validation), based on parameter calibration by up-stream runoff station and verification by validation midstream station is developed.

为解决变化环境条件下水资源评价中的&还原失真&和&还原失效&问题，本文提出基于物理参数的分布式水文模型用于变化环境下水资源评价方法的原理和假定，以及基于此原理利用上游测站流量进行模型参数率定和中游测站进行验证（简称UCMV， Up-reach for Calibration and Mid-reach for Validation）的水资源评价新方法。

From high resolution RS image of study area, gully head locations and land use information can be extracted, by performing overlay analysis on gully head locations map and flow accumulation map, slope gradient map, the slope and upslope drainage area of each gully head can be obtained.

采用的方法是RS技术与GIS技术相结合的方法，利用高分辨率卫星影像提取研究区内所有切沟的沟头位置和土地利用状况，将沟头位置与研究区的水流汇流网络图、坡度图作叠加分析，得到切沟沟头的坡度和上游汇水面积。

National Oilwell Varco is a worldwide leader in the design, manufacture and sale of equipment and components used in oil and gas drilling and production, the provision of oilfield inspection and other services, and supply chain integration services to the upsteam oil and gas industry.

无论是在全球油气田钻采设备与部件的设计、制造及销售领域，还是在油田检测设备与其他项目上以及向上游油气工业提供连锁式综合服务方面，都居世界领先地位。

Practically, there are unsteady flow in the water diversion system of the pumping station as a result of the change of upsteam stage and pump operation stage. It has important significance for the optimum operation and management of the pumping station to study on one-dimensional unsteady flow of water diversion system of the pumping station.

同时在泵站实际运行过程中，由于上游水源水位和泵站运行水位变化的影响，引水系统内往往会产生非恒定流，因此，泵站引水系统非恒定流计算研究对泵站的优化运行和管理具有重要的理论意义和实际应用价值。

TATA box and CAAT box-like elements were found in the sequence,and GC domains were rich in the far upsteam of the promoter.

序列分析表明它含有类似于TATA box和CAAT box的元件，在其远端上游区域还有多个GC富含区。

Attenuation The trp operon is also controlled by attenuation A leader sequence in the polycistronic mRNA upsteam of the coding region of the trpE structural gene encodes a 14 amino acid leader peptide including two tryptophan residues The RNA leader sequence can for several possible stem-loop secondary structures,one of which can act as a transcription terminator whilst a different stem-loop can act as an anti-terminator.

弱化作用 trp 操纵子也受到弱化作用的调控。在trpE结构基因编码区上游的多顺反子mRAN上有一段前导序列，可以编码一个含有14个氨基酸的前导肽，此肽中含有两个色氨酸残基。

Leptin receptors have been identified in neuropeptideY, Agouti-related peptide, proopiomelanocortin cocaine and amphetamine regulated transcript containing neurons of the ventromedial and ventrolateral arcuate nucleus, respectively, and in melanin-concentrating hormone and hypocretin/orexin containing neurons of the lateral hypothalamus, suggesting that the above-mentioned messengers are mediators of leptin's action in the hypothalamus.

越来越多的证据表明Leptin是调节动物体内能量代谢的极其重要的上游调控因子，而且Leptin对动物的青春期发育，生殖器官发育和繁殖功能、妊娠、胚胎发育以及造血系统都有调节功能，是动物体内早期表达的重要功能基因。

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
