Three are three major actions that Mn effects fracture behavior in the alloy at room temperature, as follow: One is that Mn fines grains, antiphase domains and weakens dislocation clog, which retain formation of cleavage crackle. The second is that Mn decreases APB energy and promotes slop and cross slip, in particular, a large number of cross slip make deformed APBs transform from line type into zigzag type and the APBs interact and cross each other, resulting in propagation of cleavage cracks. The last is that Mn raises the relative proportion of cleavage strength to grain-boundary strength and then restrains formation and propagation of cleavage crack.

Mn对合金室温断裂行为的影响主要反映在三个方面，一是Mn的存在细化晶粒和反相畴，使得位错塞积程度减小，从而阻碍解理裂纹源的生成；二是Mn的存在提高解理强度与晶界强度的相对比值，从而抑制了解理裂纹的形成和扩展；三是Mn降低反相畴界能量、促进超位错的滑移、交滑移，特别是断裂前位错大量的交滑移使形变反相畴由直线型变为折线"Z"字型，反相畴界间的相互作用、相互交错阻碍了解理裂纹的扩展。

In our system, we were unable to detect the cleavage product of overexpressed slit2. Nevertheless, it is interesting to investigate whether the cleavage of slit2 is important for its responsible function in CL1-5 or not. Our result showed that a non-cleavable slit2 showed similar growth inhibitory ability as the cleavable slit2. Therefore, the growth inhibitory ability of slit2 does not require cleavage at the reported cleavage site.

结果显示，在CL1-5细胞中，我们没有侦测到Slit2被切割的情形，并且当不能被切割的Slit2蛋白表现在CL1-5时，其抑制生长的能力与可被切割的Slit2相同，因此这个报导中的切割点与Slit2抑制生长的功能无关，而单独过度表现Slit2-C terminal蛋白片段就具有抑制细胞生长的能力。

The results showed that though apoHb could be reconstituted with all FePs, it showed different functions. Binding of apoHb with hemin can enhance the heterolytic cleavage of O-O bond of H〓O〓, but inhibiting the cleavage when FeTCPP and FeTPPS〓 were used instead of hemin. The binding of apoHb with FeTTMAPP showed negligible influence on the cleavage of O-O bond in H〓O〓.

结果表明，虽然具有阴离子基团的FeTCPP和FeTPPS〓能够在天然血红蛋白中辅基位置的附近与脱辅基血红蛋白结合，但是由于结构上与天然辅基的差别，使得血红素蛋白中相应的氨基酸残基不能起到有效的作用，因此不但不能提高反而抑制了其过氧化物酶活性；而对于具有阳离子基团的FeTTMAPP，脱辅基血红蛋白对其活性没有明显的影响。
