导致氢含量过高的原因可能在于锻后退火不足。

The main rason of leading to overhigh hydrogen content was insufficient anneal after forged.

针对这类问题和现有连续函数模拟退火算法的某些不足，本文给出了一类改进的模拟退火算法。

Regarding of the characters of this class of problems and the disadvantages of the existing simulated annealing algorithms, we propose an improved simulated annealing algorithm.

然而模拟退火算法依然存在着其自身的不足，即避免陷入局部极小值以及解空间的搜索能力和范围这两项指标不是很理想。

But simulated annealing algorithm also has weak point, that it is not very satisfactory of avoiding falling into local minimum and search capability and area of solution space.
