The results show that, with the expansion cone angle remaining unchanged, the sizing length of expansion cone does not have much effect on the residual stress of casing after expansion, but it has much effect on the expansion force required by tube expansion. The expansion cone angle has no effect on the maximum residual stress of casing, but it has remarkable effect on expansion force. When the radial component force of expansion force is greater than the material's tensile strength, the damage to the material will arise.
研究结果表明,在膨胀锥锥角保持不变的情况下,膨胀锥定径长对膨胀后套管的残余应力没有太大影响,但对套管膨胀所需要的膨胀力有较大影响;膨胀锥锥角对套管最大残余应力没有影响,但对膨胀力的影响十分明显,当膨胀力的径向分力大于材料的抗拉强度时,材料将发生破坏。

Working Principle Transmitter is composed of sensor and electronic element circuit, pressure of measured medium directly applies on sensor s ceramic diaphragm, force diaphragm to displace tinily in proportion to pressure of medium, under normal working condition, diaphragm displace no more than 0.025mm, electronic circuit detects this displacement, and convert it into standard industrial measuring signal i.e.
工作原理变送器由传感器与电子元件线路组成,被测介质的压力直接作用于传感器的陶瓷膜片上,使膜片产生与介质压力成正比的微小位移,正常工作状态下,膜片最大位移不大于0.025mm,电子线路检测这一位移量后,即把这一位移量转换成对应于这一压力的标准工业测量信号(4~20)mA。超压时膜片直接贴到坚固的陶瓷基体上,由于膜片与基体的间隙只有0.1mm,过载时膜片的最大位移只能是0.1mm,所以从结构上保证了膜片不会产生过大变形。

The study of spatial configuration and characteristics of pulsed-wire velocity probe shows that: the yaw-and pitch-response characteristics have a good behavior due to the asymmetrical arrangement of the prongs. Because the amplitude of sensor wire response signal changes with the flow velocity, the differentiated signal is selected to trigger a voltage comparator. The pulsing frequency is restricted to about 100Hz to allow the wire to cool between pulses. The first velocity probe with big acceptance cone has been developed in China, and the way of measuring the Reynolds normal and shear stress and application have been given in this dissertation.
对脉冲热线空间速度探针的空间结构及特性的分析表明:三根长支架平行且安置于同一平面的探针结构可以获得大的测量角和好的测量性能;由于传感丝的响应信号幅值随流速变化较大,故应采用微分法进行信号处理;对于5μm的传感丝由于散热时间基本不变,约为10ms,故脉冲发射的最高频率为100Hz;本文在国内首次研制成功了一种大测量窗的脉冲热线空间速度探针,并给出了测量雷诺应力的方法和实例。

The high inoculum levels increased the bacterial growth and shorten the time for antifungal substance production. The powder of rice, soybean cake, yeast, and wheat bran, CaCO3 and KH2PO4 were better nutrients for the bacteria growth and antifungal substance production. There were two stages during the fermentation process at 30℃. The growth of bacteria increased at the first 24 h and the pH of broth rose, but no antifungal activity was observed until 41 h later and reached to the highest level at 114 h.

At the same time,a tension stress is applied on theγ′phase interfaces along the direction parallel to the stress axis,which results in the lattice expansion ofγ′phase to trap the Al,Ta atoms with the bigger radius.This brings out the accumulation of the solute atoms to form the N-type rafted structure.Al,Ta atoms with bigger radius diffuse to the {100} plane to form the linked bond of the heterogeneous atoms and the stable stacking mode,this is a main reason of promoting the transformation ofγ′phase into the N-type rafted structure.And the change of the strain energy density in different interfaces of the cubical-likeγ′phase is thought to be the driving force of the elements diffusion and theγ′phase directional growth during creep.
拉伸蠕变期间,类立方γ\'相中与施加应力轴垂直的界面受水平切应力,使晶格收缩可排斥较大半径的Al、Ta原子;与应力轴平行的界面受拉伸张应力,使晶格扩张可诱捕较大半径的Al、Ta原子,由此引起的原子偏聚形成γ\'相是自由能降低的过程;其中,较大半径的Al、Ta原子扩散迁移至{100}晶面,形成异类原子结合键及稳定的堆垛方式,是促使γ\'相形成N-型筏状结构的主要原因;而γ\'相不同界面的应变能密度变化是元素扩散及γ\'相定向粗化的驱动力。
