In the course of FEM model building, tensile test experiment is taken to work out the real stress-strain curve. Ring compress test is also done in this paper, through which the friction coefficient is worked out and the friction mechanism and relevant friction model for tube stagger spinning is studied. The experiments ensured the veracity and reliability of the FEM modeling.

建模过程中，通过材料拉伸试验测定了旋压材料00Ni12Cr5Mo4TiAlV时效钢的真实应力应变曲线；利用圆环镦粗试验测定了材料在不同润滑状态下的摩擦系数，并对强力旋压的摩擦性质和摩擦模型的选择进行了研究，确保了建模关键参数的准确性和可靠性。

When the internal pressure of liquid, which dropped below the liquid at that temperature the saturation vapor pressure at the local area or the formation of steam bubble point; and stress at elevated places around the bubble suddenly breaking pressure, flow due to inertia to high speed to the center of bubble extrusion, hydraulic shock caused by the equipment.

当液体内部压力下降，低于液体在该温度下的饱和蒸汽压时，在局部区域形成汽泡或汽穴；而在压力升高的地方汽泡突然被四周的压力压破，液流因惯性以极高的速度向汽泡的中心挤压，对设备造成水力冲击。

The previous literatures indicate the inversion temperature exists under superheated steam drying with an atmospheric pressure, when the temperature of superheated steam is higher than the point of inversion temperature, the drying rate of superheated steam is faster than that of air drying, but if the temperature of superheated steam is lower than the point of inversion temperature, the drying rate of superheated steam is slower than that of air drying.

已有的研究表明，在过热蒸汽干燥时存在一个温度点，称为"逆转温度"，当过热蒸汽的温度高于"逆转温度"的温度时，过热蒸汽干燥速率比空气要快，低于逆转温度时则正好相反。由于木材浮压干燥的工业化应用是在负压区实现的，因此对真空状态下过热蒸汽干燥是否也存在"逆转温度"问题的研究非常重要。

Critical voltage for a simply supported rectangular thin plate under uniform electric field is presented by using Navier solutions.

基于经典板理论，假设材料的电弹参数为板厚方向坐标的幂函数，采用含压电耦合项的修正层合理论，推导了压电功能梯度薄板在电载荷作用下的屈曲方程，并利用Navier解，得到四边简支矩形薄板在均匀电场下的屈曲临界电压。

Thus, on the reservoir conditions of the seventh middle area of JiaMuHe and eighth area of XiaWuErHeZu, the qualities of blocking agent such as gelatification time, the gel strength, the salt resistance, the temperature resistance, the stability, the compressive strength, the selection of injection, the improvement ratio of water entry profile and the sweeping efficiency were evaluated.

评价了堵剂在七中区佳木河组和八区下乌尔禾组两种油藏条件下的成胶时间、成胶强度、抗盐性、抗温性、时间稳定性、耐压强度、选择注入性、吸水剖面改善率和驱油效率。

Relatively brief pumping phases at relatively high flow rate alternated to phases of not pumping provide for a volumetrically adequate refreshing or the electrolytes present in the battery compartments and contrast the formation of gradients in the bodies of electrolyte.

在相对高流动速率下的相对短暂的抽压阶段交替变为非抽压阶段，可以使存在于电池隔间的电解质在体积上得到充分的更新，并可以使得电解质体内的梯度更加明显。

Spring-loaded foot for free-motion embroidery, quilting and free form monogramming.

透明的脚座可清楚的看见压线的位置，使用时多将送布齿降下，靠双手自由移动车缝物件的位置，多用於车缝拼布作品的压线，适用刺绣机种

Acidizing and fracturing are performed on perforated Berea sandstone targets after perforating tests in labs.

在实验室条件下对贝雷砂岩进行射孔试验，并分别对射孔后的靶体进行酸化、压裂工艺处理，利用核磁共振和工业X-CT技术分别对未射孔的靶体、射孔后的靶体、射孔后酸化的靶体、射孔后压裂的靶体进行测试。

Experimental investigation on strongly separated flow in an annular compressor cascade ;2. The structures of separated flow, especially, vortices, inside an annular compressor cascade at large incidences have been studied baized on the flow visualization images obtained by means of Laser-sheet method and 7-hole probe measurement.

本文采用激光片光层加示踪粒子流场显示技术，观察和摄取了环形压气机叶栅在约十14大攻角下的内部流动图像；采用七孔气动探针测量了叶栅出口截面上的速度分布S通过对流场实验结果的分析，并结合本文第一部分中得到的叶片近壁区分离流结构，得到了该环形压气机叶棚中严重分离流场的分离流形态和旋涡结构。
