查询词典 downstream

In order to realize the sustainable and harmonious development,it is essential to make full use of its interborough advantages and integrated predominant resources such as petroleum and ecosystem,cultivate and develop the diversiform and multi-level structure including downstream processing of petroleum,ecotypic agriculture and tourism through the adjustment of industrial structure.

进入20世纪90年代后，经济的高速发展对石油能源的需求掩盖了油矿城市存在的各种问题，油矿城市的精力主要花在对石油资源的超强度开发上，由此加速了油矿城市发展的步伐，并引发了一系列的环境与社会经济问题，这些问题随着国家经济结构与产业结构调整以及体制改革的推进而逐步暴露出来。

Methods The IPSE gene of S. man soni was synthesized by overlapping PCR, and confirmed by DNA sequencing. The recombinant plasmid IPSE-pET32a was constructed by inserting the gene of IPSE into expression vector pET32a at the downstream of thioredoxin coding sequence.

应用重叠PCR方法合成曼氏血吸虫IPSE基因，将其定向克隆至表达载体pET32a的硫氧还蛋白序列下游，构建重组表达质粒IPSE/pET32a。

When we was three or four hundred yards downstream we see the lantern show like a little spark at the texas door for a second, and we knowed by that that the rascals had missed their boat, and was beginning to understand that they was in just as much trouble now as Jim Turner was.

朝下游划了三四百码远以后，我们还能看到那盏灯在顶舱门口忽地闪？们知道，那两个流氓找不到他们那条船，逐渐明白了他们如今正跟杰姆·透纳一样陷进了绝路。

In this thesis, we apply the equations of motion of steady Mach reflections and the oblique shock theory to derive polynomial expressions of the forms of f(r,Mo,P1) of downstream sonic and strong/weak separating conditions of reflected shocks of perfect-gas steady Mach reflections. We then obtain polynomial expressions of the forms of f(r,M0) for the limiting Mach angle condition of the above two expressions.

本论文首先应用稳态马赫反射流场运动方程式及斜震波关系式，推导出理想气体稳态马赫反射流场之反射震波下游之音速条件与反射震波之强弱分界条件之曲线解公式，并应用该曲线解公式来推导反射震波俱音速性质於Mach angle条件及反射震波俱强弱分界性质於Mach angle条件之公式。

To prove that the cloned DNA fragment can express tryptopanase,a new plasmid pET28C-TnaA , in which the cloned DNA fragment was located downstream of T7 promoter on pET28c was constructed and transformed into host BL21(DE3),a BL21 lysogen of bacteriophage DE3 in which the only promoter known to direct transcription of the T7 RNA polymerase gene is the lacuvS promoter ,which is inducible by IPTG.

为了证明质粒上的基因能表达出有活性的色氨酸酶，将这个DNA片段克隆到PET28c质粒的BamHI和HindⅢ位点上，使该片段受T7 RNA聚合酶的启动子控制，然后转化噬菌体DE3的溶源菌BL21(DE3)。

It is found that the unity Mach number isn't right at the throat but a little bit downstream of the throat.

发现马赫数为1的位置不是出现在喉部，而是在喉部下游一点的位置上。

This research examines the interaction between the strategic transfer pricing commitment and downstream innovation in a supplier-manufacturer channel,and its influences on the optimal quoted delivery time and investment decisions.We model the channel operation in a make-to-order fashion and treat the demand as being linear in price and quoted delivery time.

以一个按照MTO模式运作，并且面临交货期-价格敏感性需求的"供应商-制造商"供应链为研究对象，对该供应链中上游供应商的战略性转移定价承诺与下游制造商创新之间的交互作用，以及这种交互作用对最优的交货期设定、转移定价决策，以及渠道内各合作伙伴的行为取向所产生的影响进行了初步探讨。

According to virtual router advertise, virtual address of master device is used to upstream access device, which enables downstream traffics to have the same flow direction with that of upstream traffics via routing.

虚拟路由通告的方法则把主设备中的虚拟地址通告给上行接入设备，从而下行流量可以通过上行设备的选路，使上下行数据流向保持了一致。

Running at one megabit per second with Manchester encoding, this Ethernet standard operates on a baseband basis, providing for a single transmission at a time. Connection to the centralized hub is accomplished over UTP of 22, 24 or 26 gauge at distances of up to 500 meters in a star topology. Two pairs are used, with one providing upstream connectivity to the hub and the other providing downstream connectivity.

该以太网标准属于基带传输，单工工作方式。1Base-5与中央集线器的联接是通过UTP完成的，UTP的规格为22，24和26，采用星型拓扑，最大传输距离为500米。1Base-5使用2对UTP，1对提供与HUB的上行连接，另1对提供下行连接。

Relations between China and its downstream neighbours in the Mekong basin have long been fragile .

中国与其下游湄公河流域的邻国间的关系长期以来一直都十分薄弱。

Foods high in this vitamin include oily fish such as salmon, tuna and, and fish liver oils.

维生素D含量高的食物包括诸如大麻哈鱼、金枪鱼和鲭鱼之类的油鱼以及鱼肝油。
