1·Such currents may form, disappear, or change flow direction within a matter of hours or days.
这样一些洋流的形成，消失或改变流向可能发生在大约几小时或几天内。
2·The apparatus consists of a single board microcomputer, propeller type velocity sensor, tail fin type flow direction sensor and corresponding interface circuits and software.
该仪器以单极微机为核心，配置旋浆流速传感器、尾舵式流向传感器、相应的接口电路和软件。
3·There is no recommended flow direction and it does not require line pressure to seal.
不存在推荐流向，也不需要管线压力来实现密封。
4·The flow direction and protection of common currents under different grounding method were analyzed in detail.
详细分析了系统在不同接地情况下的共模电流的流向及其防护。
5·GATE: external direct (opposite side of the hinge). Flow direction should climb over the gasket side.
浇口：外部方向(铰链对面)。流向须爬过衬垫侧。
