The results of the pressure tests on the gate groove showed that in the process of closing and opening, negative pressure occurred near the downstream of the gate groove in relevant degrees, so monitors should be enhanced in operating application. 门槽段压力测试表明,事故闸门启闭过程中,靠近门槽下游的压力测点都不同程度出现了较小的负压,在运行中应加强监测。
In addition, if the gate profile is poorly designed, the flow separation may occur on the gate bottom edge, and then the pressure fluctuations may bring negative influence such as gate vibrations. 当闸门体型设计不良时闸底产生水流分离导致的压力波动,可能会带来闸门振动的不利影响。
For the metallic SWNTs, the G-Raman mode is found to shift to higher frequencies and narrow down its line shape at negative gate voltages, but be insensitive to positive gate voltages. 发现金属性碳管中,G-拉曼模在负栅压下向高波数移动并伴随着峰宽的窄化,但对正偏压无响应。
The complete synchronous digital frequency measurement method has thoroughly eliminated the positive and negative 1 number-counting error, because it has realized the synchronization of the measured signal, standard signal and the real gate signal. 在全同步测频法中实现了被测信号、基准频率信号和实际闸门信号的全同步,彻底消除了±1个字的计数误差。
