First, the speed of the reaction between mud acid and rock is very fast, the effective distance of acid is short, active acid can not reach deep formation.

首先，高温下常规土酸与地层矿物反应速度极快，酸液有效作用距离短，活性酸不能到达地层深部；其次，HF与铝硅酸盐的化学反应不是简单的一次反应，其副产物氟硅酸和氟铝化物还可与铝硅酸盐发生二次反应和三次反应，形成一系列不溶性的沉淀物，对储层造成严重伤害；第三，高温情况下酸液对井下管柱及工具腐蚀性很强，对缓蚀剂性能要求高。

And the influence of the paper density on the thermal conductivity of aluminosilicate fiber paper was investigated.

But despite sharply higher warrant premiums in Singapore, the disappearance of the backwardation has yet to boost CIF premiums elsewhere in Asia. In fact, in several countries they continue to fall.

尽管新加坡仓单升水大幅上涨，但铝价倒挂局面的消失并未促进亚洲其它地区铝升水CIF报价的提高，事实上，有几个国家铝升水的CIF报价持续下跌。

It thus became possible to study the cathode rays, and also the fluorescence they caused, outside the discharge tube and Lenard concluded from the experiments that he then did that the cathode rays were propagated through the air for distances of the order of a decimetre and that they travel in a vacuum for several metres without being weakened.

但是后来，1892年他在波恩大学做赫兹的助手时，赫兹让他观察了他的新发现，赫兹将一片盖上铝箔的含铀玻璃片放入放电管，当用阴极射线轰击铝箔时，铝箔下面发出了亮光。
