求翻译：于图1所示模型，脉冲放电后裂尖发生相变的区域相对于整个试件来说很小，可以把发生相变的区域看成是整个试件的夹杂，相变应力的求解可以根据等效夹杂原理进行求解。由电磁热止裂实验可把相变区域简化为扁椭圆球的形式：是什么意思？

Figure 1 shows the model of pulsed discharge crack tip phase change region relative to the whole specimen is very small, can the phase transition region as whole specimens mixed, the solution of the phase transformation stress can The equivalent inclusion principle to solve it. Split by electromagne

The model shown in Figure 1, and pulse discharge splitting after tip changes relative to the entire region of the test specimen is very small, you can make changes as the area is the entire test specimen, mixed with the phase change of stress can be mixed schematic for the equivalent. The electromag

The model in shown in Figure 1, after the pulse electric discharge the crack point has the region which changes to be opposite in the entire test sample is very small, may occur the region which changes to regard as is the entire test sample mixture, changes the stress the solution to be possible to

In the model as shown in Figure 1, after pulse discharge of crack tip of phase-change region to occur is very small relative to the entire specimen, phase-change region can be considered to be the entire specimen of inclusions, phase transition for solving stress based on equivalent inclusion theory
