In home, collective and wait-and-see atmosphere also is sent more grumous, wang Ran of CEO of Yi Kai capital says to reporter analysis,"Real good company is met forever somebody invests, but the target company that the problem is one most is belonged to actually ' can cast can not cast ', the environment is bad to be filtered easily by investor, of course, unless they fall oneself social status."

在国内，集体观望的氛围也愈发浓厚，易凯资本CEO王冉对记者分析说，&真正的好公司永远会有人投资，但问题是一大半的目标公司其实属于'可投可不投'的，环境不好就容易被投资人过滤掉，当然，除非他们自降身价。&

Before the Dragon Boat Festival of that year, suddenly a piece of bad news was come all over my hometown. It was found that a dead infant was cast away at the bottom of the mountain nearby. But I didn't believe it was true. Because I think even though infants were dead when they were born just a moment, their parents shouldn't cast them away immortally. No one could do such thing without human nature.

在那一年的端午节前夕，一则坏消息突然传遍了我的家乡，有人发现一个死婴被抛弃到了附近的山脚下但是我不信这消息是真的，因为我认为既使婴儿在一出生时就夭折了，他们的父母也不应该不道德地将其抛弃，没有人会做这样没有人性的事

The results show that Re-K-Zn compound modificator has remarkable effects in high Chromium white cast iron when the modificator has 0.5%Re+2.0%K+0.008%Zn. The modificator not only or bar-like carbides but also improved the mechanical properties of high chromium white cast iron,with its impact toughness enhanced from 7.0J/cm2 to 11.7J/cm2 and its hardness enhanced from 54HRC to 57HRC, and the wear resistance increased by 350%.

实验结果表明：Re-K-Zn复合变质剂在高铬白口铸铁中有显著作用，而且当三者的加入量约为0.5%Re+2.0%K+0.008%Zn时，能显著细化组织，使其组织中网状碳化物变为粒状或条状，提高了高铬白口铸铁的力学性能，铸态冲击韧性由原来的7.0J/cm2提高到11.7J/cm2，硬度由原来的54HRC提高到57HRC，相对耐磨性能提高了3.5倍。
