At the same time, the gas flow acting on the keyhole is simulated by finite element method. The gas flow fields of pneumatic circumferential motion and pressure distribution nephograms around and in the keyhole are obtained. Analysis shows that when plasma is blown backwards i.e., in direction towards the trailing edge of the weld pool, plasma can be eliminated better.

利用有限元法对激光焊接时保护气体在小孔内部和表面气流状况进行了数值模拟，通过对不同焊接条件下模拟形成的小孔气动扰流的气流场和压力分布云图的分析，解释了采用逆向侧吹保护气体吹除等离子体的方法，可以更有效地抑制等离子体云的产生，防止小孔塌陷，有利于维持小孔的稳定性。

Several rolls (7) are juxtaposed in a stationary machine housing, along a closed circumferential path. At each roll, a wafer cake, in the form of a hot plastically deformable material, is rolled up between a die (23) and a punch (14) to form a cone, while the rolls (7) move, turning along their path, from the input station to the output station of the cone forming machine.

文中对厚壁圆筒的径向，环向，轴向的分析，可以避免厚壁圆筒塑性破坏提供可靠的参考价值。

To adopt band type rail rolled by stainless steel and chain type drive method run circumferential movement along with the pipe to be cut by flame cutting carriage,cutting torch will run radial movement driven by ball bearing screw by step motor along with the pipe to be cut,the above two dimension movement compose to inclined cutting movement of cutting torch,the inspection of circumference position of cutting torch,the determination of radial position and return point of cutting torch all controlled by SCM.

为了满足钢管斜截切割的要求，建立了钢管斜截切割的数学表达式，采用不锈钢轧制的带形轨道和链式传动的方式使火焰切割小车沿被切钢管做周向运动，割炬沿被切钢管的轴向运动由步进电动机带动滚珠丝杠完成，上述两维运动合成为割炬的斜切运动，割炬周向位置的检测、割炬轴向位置及折返点的确定均由单片机控制完成。

Therefore, the choice of single mode in the examination and the frequency-thick band of mode has been given a particular illumination separately in the paper, following a relative numerical simulation. And a multi-cyclical sine signal modulated by Hanning window is used to simulate the excitation wave, and then an inspected ring of nodes is established to receive the echo, finally how the length of the circumferential cracks, the width of the axial cracks and the degree of the thickness-reduce effect the result is explained through the analysis of the result, further more, the reflection factor in the defect has been calculated.
