In this paper,the boundary singular kernel method in Reproducing Kernel Paicle Method has been applied to impose the essential boundary conditions in EFGM by revising the MLS shape function.The stress field and the displacement field are analysed by linear elastic theory.The contour integral method is used to calculate the J-integral,then the stress intensity factors of mixed-mode crack is acquired.The correctness and the validity of the method are validated.

本文将再生核质点方法中的边界奇异权方法引入EFGM中，通过对MLS形函数进行修正实现了本质边界条件在节点处的精确施加；运用线弹性断裂理论分析裂纹板的应力应变场，采用围线积分法计算J积分，给出了复合型裂纹板的应力强度因子的无网格伽辽金方法。

Some applications can not use the same method to close, then we should start to heat, such as pressing "CTRL + ALT + DEL"; the other should pay attention to the clipboard if the store a picture or image, picture or image is to occupy a large number of memory, then just cut and paste words, you can put the clipboard memory obliterated the original picture, so that it occupied a large number of memory released; Also, print a document in the background will use up a lot of memory space.

有些应用程序不能用一般的方法关闭，这时就要进行热启动，如按下"CTRL+ALT+DEL"；另外要注意剪贴板中如果存储了一幅图片或图像，图片或图像是要占用大量内存的，这时只要剪贴几个字，就可以把内存中剪贴板上原有的图片冲掉，从而将它所占用的大量的内存释放出来；还有，在后台打印文件，也会占用大量的内存空间。

Research on the flux boundary conditions in the numerical simulation of line-heating process With the development of computer technique in recent years, the numerical simulation method has been applied more and more widely for the research of distortional mechanism and regulation in line-heating process.

1水火弯板数值模拟中热边界条件的研究近几年随着计算机技术的发展，数值模拟法在对水火弯板变形机理和变形规律的研究中得到了越来越广泛的应用。

Regarding four phase-stepping method, the difference of new instrument is that the original instrument requires four quarter-wave plates and needs to set up eight different angular magnitudes, whereas the new one requires only one quarter wave plate and changes the angle of analyzers.

在三场架设中，有别於一般需四道光路和输出时的四分之一波板，并且只要调整检偏器之角度便可得到三张的包裹相位图；而四场架设里，也只需多一片输出时的四分之一波板，使其中两道光路的结果为圆偏光，此外，仍然只转动检偏器之角度即可，相较传统的四场，除了元件的简化外，角度设定也较简单容易；六场平偏则改善了一般平偏或圆偏只能单一取得主应力角或因四分之ㄧ波板所造成的影响。

Experiment 1. Observation of electron beam deflection in the electric field Will voltage electron beam deflection plate to tie the direction switch "is" location, rotating clockwise direction deflection plate voltage Potentiometers (RP2), the electron beam is deflected upward, the greater the voltage between the deflection plate, the electron beam deflection angle the bigger.

实验一。观察电子束在电场中的偏转将电子束偏转板电压方向开关扳到&上正&位置，顺时针方向旋转偏转板电压电位器(RP2)，电子束则向上偏转，偏转板之间电压越大，则电子束偏转的角度越大。

Yu,1991,the plastic limit analysis for oblique plates and the unified limit loading expression are given,which includes a set of solutions from the single-shear yield criterion(Tresca,1864)to the twin-shear yield criterion (M.H.Yu,1961).The relative curves between qand b are also got for square plates and rhombic plates.

从而得到一系列从单剪屈服准则(特雷斯卡，1864)到三剪屈服准则(米泽斯，1913)再到双剪屈服准则(俞茂宏，1961)的各种斜板的极限载荷，并得到矩形板和菱形板的极限均布载荷p随不同屈服准则的变化曲线，文献中已有的解均为统一解析解的特例。

Moreover, the column deflection of hull saddle shaped steel plate caused by dead load is calculated using the ANSYS system, and the date base of the calculation of dead load forming for hull saddle shaped steel plate with varying the plate thickness is established.

根据在大连造船新厂的调查和分析可知，在全部展开外板中，平板自重成型率占1 0 %左右，具有较小横向曲率的外板自重成型率占1 5 %左右，其余的外板需经不同程度的水火弯曲加工而达到成型的目的。
