  这将是一场消耗战,持久战,疲劳战,对任何人都不会有好处。这些公报的中英文版本一致,表述同样立场。

中国人民只有坚持改革创新精神,坚持做好自己的事情,不受其它别用用心的干扰。  党的十八大以来,我国经济实力再上新台阶,成为世界经济增长的主要动力源和稳定器,也即成为世界经济发展最为重要的网络节点之一。

    现今,居然也会发生农夫与蛇一样的事情,有点匪夷所思。因为中国既没有这个闲钱和实力,也没有那种野心和胆子。

    在国家间的相处中,日本保守派认为安全上只存在零和游戏,只有增强自身实力才能获得想要的东西。对于应对复杂性公共安全风险和突发事件而言,综合协调是最为关键的,但也是最难实现的。

这些指示和信息都包含极大不确定性。

  自此以后,美国一直在对台军售以及武力干涉台湾问题上打擦边球。

  忽听催征烽鼓响,高天又见凤凰啼。东北话大茬子味直白幽默,吴侬软语含蓄温婉充满古意,粤语铿锵有力绕梁三日,四川话麻辣生动侠气十足。

  冷战结束及苏联解体为俄换来的与西方关系改善损失殆尽,莫斯科几乎回到了自己在冷战时期的地缘政治原点。

  再看看美国最骄傲的苹果,现在就已遭到中国国产手机的严峻挑战。  第四,也是最重要的,美国国力在小布什政府初期达到了一个顶峰。

  这也是海外华人华侨利己利国的责任所在,这里的国,既是作为自己母国的中国,也是加入国籍的所在国。

  据日本《读卖新闻》报道,与地震前相比,岩手、宫城、福岛三县35个沿海市町村人口减少了17万以上。在实现乡村振兴的新征程上,不能让假冒伪劣食品成为其中的一块绊脚石。

The academic that tested a 71,000 volt on himself for research

  我们估计,围绕脸书的争论和讨伐会是一场乱仗,打不出所以然来。

An academic at the China Academy of Engineering and founder of electrostatic safety research in China, is renowned as the first person to determine the highest static potential of the human body. Liu Shanghe even went so far as to prove his conclusion with an experiment on his own body.

The 80-year-old scientist's fight with the invisible "ghost" static began in 1983 when he taught fundamental physics at Ordnance Engineering College in North China's Hebei province. Shocked by a series of tragedies caused by static, Liu became keenly aware that weapons and ammunition safety can only be ensured by solving problems caused by static.

Already in his 40s, Liu shifted his research focus from semi-conductors to static and ammunition.

Speaking about his decision, Liu said that "to explore this unknown area, I was willing to learn from the beginning like an elementary school student."

Through unremitting efforts, he published a scientific paper on how to alter polymeric material to make it static-free in a few years. That was a finding proposed for the first time in China and also gained international acknowledgment.

Based on a large quantity of experimental data, he and his colleagues invented five instruments including an electrostatic potential dynamic testing instrument.

Through both theoretical calculation and precise experiments with the instrument, Liu's conclusion on the highest level that human body's static potential can reach is higher than those determined by experts in the United States and United Kingdom.

In 1992, Liu boldly decided to experiment on his own body and finally reached the number 71,000 volt.

He would never forget his days spent working in the lab. Long-time exposure to hazardous gas and radiation caused his white blood cells to plummet to 2000 from the normal level of 5000. And over-work made this 1.8-meter-tall man shrink to as thin as 60 kilograms.

In his wife's eyes, he has little concept of free time. Even at home, most of his time was spent in his study continuing his research.

Liu has recieved many awards for his achievements, including the highest ones of science and technology in the country.
