Although we have not a tool to directly modulate the cellular Cdc42/Rac activity at present, nevertheless, from the abolish of BDNF-triggered attraction by either DN-Cdc42 and CA-Cdc42, we propose that an intracellular Cdc42 activity gradient may also be sufficient to determine the turning direction, say, filopodia extend preferentially at the higher Cdc42 activity side, and the growth cone turn towards this direction in the hence.

虽然我们目前还没有一个直接操纵细胞内 Cdc42或其下游分子活性的方法，但从 DN-Cdc42和 CA-Cdc42均阻断到 BDNF 和 ryanodine 的吸引作用来看，我们推测， Cdc42的活性梯度很可能也能够决定生长锥转动方向，即丝状伪足在 Cdc42活性高的一侧优先延伸，生长锥朝向该侧转动。

In derivations of these equations, the discharges which flow through the check gate are calculated with the orifice equation for building the relationship between upstream pool and downstream pool of the gate.

在公式的推导过程中，过闸流量采用的是大孔口出流公式，没有采用工程中常用的闸孔出流公式，这是为了便于建立上、下游渠池间的联系。

Make your streamer come alive by altering the speed of its "swim", twitching the streamer a few feet upstream then letting it drift back down, or by pulsing the fly by bobbing the rod tip.

改变游动之速度可使饰带毛勾泳姿更为生动，把饰带毛勾向上游抽动再样其飘流到下游，或挑动飞蝇竿尖使毛勾脉冲跳动。

The research in this thesis successfully resolved the downstream energy dissipation and erosion control problem of Yingping water power station, and thoroughly studied the hydraulic characteristics of the training frusta, which offers certain reference values for similar project problems.

该论文研究成果解决了阴坪水电站闸坝下游消能防冲实际问题，并深入探讨了导流墩的水力特性，为类似工程消能防冲问题的研究提供了参考依据。

The GIPS/GDPS Series of Automatic Shut-off Valves are safety devices designed to stop the flow of gas when the downstream pressure of the valve reaches a value larger than and/or smaller than the preset operating limit.

GIPS ﹝升压感应关断型﹞与 GDPS ﹝降压感应关断型﹞系列自动关断阀为安全设备，设计当此阀下游压力达到大於或﹝和﹞小於预定操作限度的压力值时，来中断瓦斯流动。

They spent all their time in playing gently, in bathing in the river, in making love in a half-playful fashion, in eating fruit and sleeping.

我明 白过来后，赶紧脱掉衣服，在下游一点的地方膛水过去抓住那小家伙，把她安全地拉上了岸。

In addition,a major difficulty still exists in downstream processing because 2,3-BD has a high-boiling point and a high affinity with water.

此外，由于2，3-丁二醇具有较强的亲水性和较高的沸点，且发酵液成分复杂，因而该产品下游分离比较困难。

After inserting the mutant fluorescence protein gene into the vector, the novel vaccinia virus vector p16H1FP and p16H2FP to express proteins as fusion products containing an additional amino-terminal stretch of six histidines were constructed.

我们用PCR扩出N-端融合6×His·Tag多克隆位点基因序列，插入p16表达载体，并在其多克隆位点下游装入带有巨细胞病毒启动子的突变型荧光蛋白基因，构建成两个读框的N-端融合6×His·Tag并带有荧光蛋白报告基因的分离型痘苗病毒表达载体。
