发帖数: 14194 | 4 如果美国人卡住helium的出口，再控制住卡塔尔的氦气出口（直接禁运就行），
在目前的基础上，氦气的价格翻5倍都跟玩似的。
真搞急了，可以直接给中国拔管。
这样搞得话，中国大学，科研机构的核磁，还有需要超低温的超导研究那摊子，
直接趴窝；中国医院的核磁共振仪等等，也直接歇菜了。
事实上，2007年，美国将氦气核定为战略物资而作出限制粗氦产量、限制氦气出口量等
一些举措来保护美国本土的氦气资源。导致全球液氦价格由原来60～80元/每升，
上涨到目前200元/每升以上，更是一度飙升到300元/升。现在价格已经超过300块了。
美国这边的英制单位和标准单位换算很蛋疼，但是价格飙涨是很明显的。
2018年9月1日的消息， 新出的氦气拍卖价格比一年前又涨了135%。
看看美国人卖氦气本事，再看看中国有水快流，贱卖稀土的水平，贸易战的结局
恐怕好不了。

上面），也只是暂时一两天有用。
强烈建议楼住快去换掉radiator！！！！！！！！！！！！！！！！！！
者看上去是个小问题，但是能引发不可负担的结果。
原因是，当radiator不密封时，漏水事小，但里面的压力达不到13 lb以上，液体的沸
点就会下降，很快被蒸发，而起不到冷却的作用。要是继续开车的话，引擎不能被很好
的冷却，很容易烧引擎。结果是要不然head gasket烧坏，维修费用在1500以上，要不
然engine head烧坏，费用更高。
这个危险不值得冒！去Autozone自己买一个radiator,一般在200刀以内。不管是自己换
