The relation between grain size and strength of the duplex stainless steels and influence of grain size on properties of hydrogen induced cracking in these steels have been investigated. The Hall-Petch relation between grain size and strength of the steels is also followed.The susceptibility to hydrogen induced cracking of the steels increases with increasing grain size.

采用非线性反馈控制,用附加了带参数的正弦项对Chen系统进行了有效的控制.随着参数k的逐渐增大,系统的动力学行为呈现出一系列的变化.数值研究结果表明:随控制参数的增大,驱动信号的强度渐大,混沌系统由混沌运动到周期轨道,最终到一相点.
