查询词典 upstream

The toxin-antitoxin system consists of a pair of co-expressed genes. The upstream gene encodes an unstable antitoxin protein, and the downstream gene encodes a stable toxin.

The measured total flux of oil-water and temperature difference between upstream and downstream of the heater were employed as inputs, and the oil holdup was used as output of LSSVM, the relation between input and output was trained and the ideal model of oil holdups was obtained by applying a modified PSO to determine the optimal parameters of LSSVM automatically.

该方法将测量的油水总流量和加热器上下游温差作为LSSVM输入，含油率作为输出，对含油率与温差和总流量的关系进行训练，通过改进的PSO优化LSSVM的参数，建立了含油率的优化模型，并用测试数据对含油率的模型进行了比较。

You should aim to collaborate with other Ubuntu maintainers, as well as with the upstream community that is interested in the work you do.

你的工作开展应该是透明的，并且当为Ubuntu制成补丁时就反馈给社区而不是在版本发布时。

TRS utilizes this property and has three main characteristics:(1) zonal effluent cap is set by taking into account the water pollution loads transferred from the upstream zones;(2) the trading ratios are set equal to the reciprocals of the exogenous transfer coefficients among zones; and (3) permits are freely tradable among dischargers according to the trading ratios.

此交易比制度具备三项特性：(1)预先扣除上游下流之污染量，设定分区排放量上限；(2)交易比等於外生之转移系数的倒数；(3)污染源依据交易比，自由交易排放许可证。

Then, this system was applied to analyze the influence of interfering factors towards the parameters of LRE for monopropellant (H_2O_2) and bipropellant (N_2O_4/UDMH) system, which include the effect of upstream pressure of the tank and the diameter of the pipelines on the thrust. Thus, the variety of main parameters such as thrust, impulse, and chamber pressure were obtained at rated condition.

本文还以MATLAB软件作为设计平台，使用M文件编写了挤压式液体火箭发动机的静态系统仿真程序，分别针对单组元(H_2O_2)和双组元(N_2O_4／UDMH)推进系统进行了干扰因素对发动机参数的影响分析，包括贮箱上游压力以及管路直径对发动机推力等参数的影响。

In the Arachosian capital, Kapisakani, the road divides: a traveler coming from the west can go upstream along the Tarnak to modern Kabul and the Punjab, or to the southeast, across the Bolan pass to the lower Indus .

在Arachosian资本， Kapisakani 秒，道路分为：旅行者来自西部地区可以去上游沿塔尔纳克现代喀布尔和旁遮普邦，或东南，整个博览传递给下游。

In the Tibetan language in the Brahmaputra means "down from the highest peak of water upstream."

雅鲁藏布江---在藏文中的意思是&从最高顶峰上流下来的水&。

Xanthus DK1622 by PCR, and inserted the fragment into a site upstream of lacZ, resulting in the recombinant plasmid pZCY13. The plasmid pZCY13 was transformed by electroporation to DK1622, producing a mutant ZC16-18 ?

从黄色粘球菌DK1622基因组上PCR扩增MXAN1334基因内部部分片段，插入载体pZCY11上lacZ基因的上游，构建重组质粒pZCY13，将其转入DK622菌株，获得MXAN1334基因插入失活突变株ZC16-18。
