在上游

First , erosion resulting from excessive deforestation in the upper reaches of the river and , second ,heavy silting which raised the riverbed in the main channel .

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。

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。

Some of the key results from the show were Best Wine of the Show to Tallijancich Wines for its NV Julian James Reserve Muscat, Best Value for Money Wine to Houghton Wine Co 2007 Moondah Brook Chenin Blanc, Best Verdelho 2007 to Neilson Estate Wines (a relative newcomer in the SwanValley) and Best Shiraz 2006 Upper Reach.

葡萄酒展的亮点包括颁发给塔利杨希奇葡萄酒厂的最佳葡萄酒奖，获奖的葡萄酒是 NV 朱丽安·詹姆斯保留葡萄酒马斯卡特，颁发给修顿葡萄酒公司的物有所值葡萄酒奖，获奖的葡萄酒是2007年满达溪陈宁白朗，颁发给尼尔森庄园葡萄酒厂（在天鹅河谷该厂是个较新的厂）的2007最佳维徳和葡萄酒奖以及2006年上游最佳雪拉兹葡萄酒奖。

In turn, this explains why 70% to 80% of the flow of the upper Indus and Yarkand rivers occurs in six to 10 weeks of summer usually in July and August lagged until winter snow sitting on the ablation zone has melted away to expose the ice.

反过来，这又解释了为什么印度河上游和叶尔羌河70%到80%的水量都在夏季6到10周内出现，慢慢减少，直到冬季消融区的降雪全部消融露出冰面。

The Upper Indus and Yarkand basins have around 21,000 square kilometres of glaciers, the larger fraction in the Greater Karakoram, or about 16,500 square kilometres.

印度河上游和叶尔羌河流域的冰川面积有2.1万平方公里，其中较大的一片分布在大喀喇昆仑山脉，约有1.65万平方公里。

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
