Generally, nitrogen solubility in HNS increases with high pressure, actually it abides by Sieverts rule in low-pressure scope, a difference comes when high pressure and high content alloys elements.

氮在液态铁合金中的溶解度随温度变化存在折点，在不同相中具有不同的变化规律，但总的趋势是氮溶解度随温度升高而增大。

Will use the hydraulic control valve mouth of the tongs pressure implementation ahead of time adjustment for us, will be precise the control mouth of the tongs pressure, by will cause the mouth of the tongs pressure average, will cause on the main journal the remaining stress average, by will enhance rollings the processing quality.

为今后采用液压控制阀对钳口压力实行提前的调节，以精确的控制钳口压力，使钳口压力平均，曲轴颈上的残余应力平均，以提高滚压加工质量。

For reducing the room, I design the base chest into the form of the control tank. The pedestal oil box located the under layer, the super stratum is the integration control area of the hydraulic pressure and electrical control. Join the drive electromotor with the hydraulic pressure pump by the link flange .All the hydraulic pressure control clique install on the assemble piece. It will reduce the collectivity area.

为了减少布局空间，将台钻下装部分设计成箱体控制柜的形式，底座油箱置于下层，上层为液压及电气集成控制区，将驱动电机用联接法兰联成一体，将所有的液压控制阀集成安装在一个大的阀块体上，大大减小了台钻的整体布局。

The results show a reversed-flow region is formed at the tip of the pressure side due to the influence of the outside hot combustion gas and the pressure side tip thickness. The pressure gradient makes the coolant flow exit from the trailing edge slot first separates from the trailing edge cut-back, and then affected by the expansion wave, the coolant gas reattaches the cut-back of the trailing edge after passing a certain distance.

研究表明，由于外流和叶片叶盆尾缘厚度的影响，叶盆尾缘端部形成局部回流，叶片尾缘劈缝气体流出后受压力梯度的影响先抬起与叶背面分离，在流过一段距离后由于跨音速流膨胀波的作用，冷气流再次附着在叶背尾缘上。

Then, according to HVS, the vibrant valve is designed. On the basis of coupling analysis and simulation study of the vibrant valve and the release valve, the simulation curve about the fluid pressure variation in the pile-driving oil pipe is obtained, by which the relationships among the highest pressure value, average pressure value and the pile-driving frequency are obtained.

然后根据液压振动系统设计了振动开关阀，并重点对液压振动系统中的溢流阀和振动开关阀进行了耦合分析和仿真研究，得出压桩油路中流体压力变化的模拟曲线，并根据模拟曲线分析得出流体压力的最高压力值、平均压力值和压桩频率间的相互关系。

Though Elastic pressure plate fine blanking has many structures, those structures, running mode and materials forming are similar just with different modes of pressure plate, such as odontoid gear ring pressure plate, indent plate, subulate plate and convex plate etc.

强力压板精冲虽然有多种模具结构形式，但就模具结构、动作方式和材料变形而言，都基本类似，只是压板的形式不同。

The pressure drop of airflow consisting of pressure drop of the perforated plate and liquid-layer is mainly influenced by the plate dimension and bare tower velocity, with the increasing of bare tower velocity, pressure drop of the perforated plate increases. The experimental data are used to develop a correlation as follows:ΔpD＝1.04×10－82g This correlation should be used whenβ＜5％,0.299m/s＜u＜

空气流动的阻力主要由孔板阻力和液层阻力组成，孔板阻力主要受多孔板的几何尺寸及空塔速度的影响，空塔速度越大，孔板阻力越大，对实验数据进行回归分析得出的实验关联式为：ΔpD＝1.04×10－82g 公式适用范围：β＜5％，0.299m/s＜u＜
