求翻译：图2为不同电流密度下相变区域的大小对相变应力的影响，有图2可知相变应力为压应力，并且随着电流密度的增加而增加，亦随相变区域的增加而增加。是什么意思？

Figure 2 phase transitions for different current density region the size of the impact on the phase transformation stress, Figure 2 shows the phase transition stress is compressive stress, and increased with increasing current density increased in tandem with the increase of the phase transition reg

Figure 2 is a different current density, phase change the size of the area of the phase-change, stress can be seen in Figure 2 for the same strain, stress and pressure as current density is increasing, along with the phase change is increasing.

Figure 2 is under the different current density changes the region the size paraphrase to change the stress the influence, has Figure 2 to be possible to know changes the stress is the compressed stress, and increases along with the current density increase, also along with changes the region the in

Figure 2 is a phase-change the size of the area under different current densities on the stress effect of phase change, Figure 2 is turning stress into compressive stress and increases with the increase of current density also increases with increases in phase-change region.
