求翻译：从图2、图3和表3可以看出，相同的固溶温度（1090℃×2min），715℃特殊热处理不同时间的试样，随着处理时间内的延长，耐晶间腐蚀性能迅速上升，10h后趋于不变；不同温度特殊热处理2h的试样，随着热处理温度的升高，耐晶间腐蚀性能先稍微下降后迅速上升，750℃以后趋于不变。690合金耐晶间腐蚀的较好的热处理制度为1090℃×2min＋715℃×（≥10h）或（≥750℃）×2h。是什么意思？

It can be seen from Figure 2, Figure 3 and Table 3, the same solution temperature (1090 ° C x 2min), the sample of 715 ° C special heat treatment to different time, with the extension of the processing time, the resistance to intergranular corrosion to a rapid increase in tends to remain unchanged,

From Figure 2, figure 3 and table 3 it can be seen, the same solution temperature (1090 °C x 2 min) and special heat-treated 715 ° C samples at different times, with the extended processing time, corrosion-resistant crystal rose rapidly, and after 10 H in different temperature does not change; speci

From Figure 2, and Figure 3 and table 3 can seen, same of solid dissolved temperature (1090 ℃ x2min), 715 ℃ special heat treatment different time of specimen, as processing time within of extended, resistance Crystal between corrosion performance quickly rose, 10h Hou tends to does not variable; dif
