Moments of force are small: Because the damper plate weight is light, the damper plate and the guide rail and the rubber packing friction drag is small, therefore causes the handwheel operation moment of force to be small

力矩小：由于闸板重量轻，闸板与导轨及橡胶密封条的摩擦阻力小，故使得手轮操作力矩小

The scheme implementation of cutting head of protrusive rocks of the Tiaoguan and single sluice control can basically solve the problem of head of protrusive rocks and some dangerous situations.

针对调弦口及调关弯道存在的问题，提出了调关弯道裁弯与双闸控制和调关矶头削矶改造与单闸控制2类治理方案，这2类方案各有优缺点，基本上都能达到调弦口的治理目标。

In high-voltage var compensation field, when switching the capacitor banks by mechanical switch, it is easy to bound when it closes and to restrike when it opens, and the mechanical switch can not be switched frequently. When switching the capacitor banks by electronic switch in series, it needs dynamic and static voltage sharing circuit and synchronous triggering circuit. It leads to complex structure and high cost.

为解决当前高压无功补偿领域采用常规机械开关投切电容器组开关合闸时触点弹跳产生过电压，分闸时易重燃及不可频繁操作，而采用串联固态电子开关需要相应的动、静态均压及同步触发电路导致系统结构复杂且成本较高的问题，提出一种基于新型高压投切开关的高压动态无功补偿装置。

A two-dimensional mathematical model of flow and sediment is used to calculate and analyze the erosion of the riverway at Cao'e River Gate after its completed construction.

采用平面二维水流泥沙数学模型对曹娥江大闸建成后闸上河道冲刷情况进行了计算分析。

The companys main products are: valve type - automatic gate backwater valve, dual check valve, rubber gate valve, butterfly valve, such as three-ring seal products; category --- atmospheric-fired boilers, fuel, Gas-fired boilers and other products.

公司的主导产品有：阀类－－回水自动启闭阀、双路止回阀、橡胶闸板闸阀、三环密封蝶阀等系列产品；锅炉类---常压燃煤、燃油、燃气等锅炉系列产品。

Thus, self-sealing valve fully closed position is based on the location of gate to determined.

由此可见，自动密封的闸阀全关位置是按闸板的位置来确定的。

Valve closed, the sealing surface can only rely on media pressure to seal, that is, to rely on media pressure to ram pressure to the other side of the sealing surface of the seat to ensure the sealing surface of the seal, which is self-sealing.

闸阀关闭时，密封面可以只依靠介质压力来密封，即依靠介质压力将闸板的密封面压向另一侧的阀座来保证密封面的密封，这就是自密封。

Valve closed, sealing surface can only rely on Rising Stem Resilient Seated Gate Valve media pressure to seal, in which the medium pressure to ram pressure to the other side of the sealing surface of the valve seat to ensure the sealing surface of the seal, which is a self-sealing.

闸阀关闭时，密封面可以只依靠介质压力来密封，即依靠介质压力将闸板的密封面压向另一侧的阀座来保证密封面的密封，这就是自密封。

When closed-depending on the type of ram selected-they will seal around the drillpipe, seal off the open hole, or in emergencies shear the drillpipe and seai off the hole, The basic concept of the ram BOP has not changed in 50 years.

当关闭时-取决于被选择的闸板的类型-它们会封闭钻井管，封锁开放的孔洞，或者在紧急情况下切断钻井管并封住孔洞。闸板防喷器的基本概念在五十年内没有改变过。

Siltation in the downstream area is the key problem of construction of a barrage in tidal estuaries.

潮汐河口建闸的关键问题是闸下淤积。

Neither the killing of Mr Zarqawi nor any breakthrough on the political front will stop the insurgency and the fratricidal murders in their tracks.
