It also explained why nitroglycerine, the well-known explosive, soothes the heart pain known as angina.

这也解释了为什么酸油，即人们所熟知的炸药，能够缓解心。

Put hope and desperation together, and what do you get? The political equivalent of nitroglycerine.

把希望与绝望放在一起，你会得到什么呢？在政治上这等同于一个炸药包。

For example, the heart medicine nitroglycerine becomes unstable at high heat and is known to lose its potency fast.

例如，心脏病药物油在高温下不稳定，且它的效力会迅速丧失。

What exactly nitroglycerine does to the circulatory system remained a mystery for a long time.

酸油究竟对循环系统有什么作用，长以来一直是个谜。

After his return to Sweden in 1863, Alfred Nobel concentrated on developing nitroglycerine as an explosive.

1863 年回到瑞典后，阿尔弗雷德·诺贝尔专注于开发油作为炸药。

Alfred Nobel became very interested in nitroglycerine and how it could be put to practical use in construction work.

阿尔弗雷德·诺贝尔对油及其在建筑工程中的实际应用产生了浓厚的兴趣。

To make the han-dling of nitroglycerine safer Alfred Nobel experimented with different additives.

为了使油的处理更安全，阿尔弗雷德·诺贝尔试验了不同的添加剂。

But by around 1880, doctors began to realize that nitroglycerine was even more effective and faster acting for heart problems than amyl nitrite.

但是到了 1880 年左右，医生们开始意识到，酸油比亚酸戊酯对心脏病的疗效更有效、作用更快。

There he met the young Italian chemist Ascanio Sobrero who, three years earlier, had invented nitroglycerine, a highly explosive liquid.

在那里，他遇到了年轻的意大利学家阿斯卡尼奥·索布雷罗 (Ascanio Sobrero)，后者在三年前发明了油，这是一种极易爆炸的液体。

He also realized that the safety problems had to be solved and a method had to be developed for the controlled detonation of nitroglycerine.

他还意识到必须解决安全问题，并且必须开发一种方法来控制油的引爆。

Even after it became an accepted treatment for angina, the technical term for chest pain, what exactly nitroglycerine does to the circulatory system remained a mystery for a long time.

即使在它成为心（胸的技术术语）的公认治疗方法之后。酸油究竟对循环系统有什么作用，长以来一直是个谜。

He soon found that mixing nitroglycerine with kieselguhr would turn the liquid into a paste which could be shaped into rods of a size and form suitable for insertion into drilling holes.

他很快发现，将油与硅藻土混合会将液体变成糊状，可以将其塑造成适合插入钻孔的大小和形状的棒。

Nobel named his creation dynamite, and it turned out that the ingredient that made a deadly explosive had another life-saving property, hinted at when workers in dynamite factories noticed that coming into contact with nitroglycerine seemed to ease chest pains.

诺贝尔将他的发明命名为炸药，事实证明，制造致命炸药的成分具有另一种拯救生命的特性，炸药工厂的工人注意到，接触油似乎可以缓解胸。
