喷嘴

Again, assuming a 1-D flow of a perfect gas, the, gas properties at any nozzle area ratio can be obtained by knowing a property of the gas called the ratio of specific heat capacities, or gamma.

再次，假设一维流动的一个完美的气体，气体性质在任何喷嘴面积比例可以得到知道的一个性质的气体所谓的比例，具体的供热能力，或伽玛项。

Using well-known compressible flow equations for a perfect gas, tables of flow properties have been generated for different values of g.

fromthese表，气速，马赫数和喷管推力系数的（ cf -定义为推力除以产品总商会的压力和喉咙区），得到了作为一个功能的喷嘴面积比例和G 。

Turbines are equipped with safety devices for pressure,live steam pressure,extraction steam pressure vacuum,axial displacement of rotor,and the monitoring devices for speed,vibration,temperation,pressure etc.

本设计对凝汽式汽轮机调节系统的选用﹑原理进行了研究，选择了电液调节系统，介绍了其工作原理，完成各部件设计，配汽采用喷嘴调节法。调节气阀的启闭由油动机通过横梁﹑两阀杆和杠杆系统进行控制。

Drilling mud is pumped down the inside of the drill pipe, through jet nozzles in the bit, and into the "annulus".

钻井泥浆被泵入钻杆内部，从钻头的喷嘴流入环形空间。

In order to improve aspiration-efficiency of the jet aerator, an air-in pipe called inner pipe was set up to add one more aspiration in the aerator muzzle.

为提高射流增氧机的吸气效率，在其射流器喷嘴内增设吸气管以增加一次吸气。

Therefore the feeding speed can be controlled and maximal pushing force can be restricted by regulating the pressure of the hydraulic cylinder. The flexible jet pipe advances along the jetted hole with the tractive effort of the nozzle.

喷管在喷孔内主要处于承受轴向张力状态，喷嘴对喷管的牵引作用是柔性喷管能顺着喷孔送进到较大深度的主要原因。

In an impulse turbine steam is admitted through a nozzle and directed against one or more rows of blades.

当蒸汽通过冲力式涡轮机的喷嘴时，将会直接地冲击在一排或者几排的冲力式涡轮机的叶片上。

Digital simulation is an important step for torpedo turbine engine design. This paper investigates the modeling and simulation of unclosed cycle and partial flow two-stage impulse torpedo turbine in design condition and two non-design conditions. The control modes of turbine in non-design conditions are discussed.

进行鱼雷涡轮动力装置数字仿真是设计涡轮机的重要步骤，为此，该文针对鱼雷涡轮机设计和研制的需求，采用理论分析、经验推导和实验研究相结合的方法建立了鱼雷开式循环部分进气纯冲动式复速级涡轮发动机设计工况及2 种常见变工况的数学模型，着重讨论了变工况过程涡轮机的调节控制方案，提出了简便易行的开关喷嘴控制方法，并对其进行了数字仿真研究。

Passing through the nozzle at the highest speed, Impulse turbine steam directs against a row of blades which assembled in the axles of Impulse turbine with radiation shape.

当蒸汽以最高速度从喷嘴里喷出时，便冲击一列呈辐射状安装在涡轮机主轴上的动叶片。

The modern high-pressure injection systems VP44 distributor-pump, Unit Injector and Common Rail have transformed the ponderous, smoke-belching slowcoaches of yesterday into the sporty, fuel-efficient and clean automobiles of today.

现代高压喷射系统vp44经销商泵，泵喷嘴和共轨已经改变了笨重，不吸烟打嗝slowcoaches昨天进入动感，节约燃料和清洁汽车的今天。

I will endeavour to find you some assistance.
