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

这也释了为什么硝酸甘，即人们所熟知炸药，能够绞痛。

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，脏病药物硝化甘在高温下不稳定，且它效力会迅速丧失。

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

硝酸甘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·诺贝尔专注于开发硝化甘作为炸药。

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

阿尔弗雷德·诺贝尔对硝化甘及其在建筑工程中实际应用产生了浓厚兴趣。

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

为了使硝化甘理更安全，阿尔弗雷德·诺贝尔试验了不同添加剂。

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，硝酸甘比亚硝酸戊酯对脏病疗效更有效、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，他遇到了年轻意大利化学家阿斯卡尼奥·索布雷罗 (Ascanio Sobrero)，后者在三年前发明了硝化甘，这是一种极易爆炸液体。

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

他还意识到必须决安全问题，并且必须开发一种方法来控制硝化甘引爆。

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.

即使在它成为绞痛（胸痛技术术语）公认治疗方法之后。硝酸甘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，将硝化甘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大小和形状棒。

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.

诺贝尔将他发明命名为炸药，事实证明，制造致命炸药成分具有另一种拯救生命特性，炸药工厂工人注意到，接触硝化甘似乎可以胸痛。
