Ammonia nitrate, potassium chloride, and aluminum powder.

硝酸氨 氯化钾 还有铝。

The nuclear reactions in " Oppenheimer" were also created by producing actual explosions (albeit not nuclear ones), brightened by aluminium and magnesium powder.

《奥本海默》中核反应也是真正爆炸(尽管不是核爆炸)，用了铝和镁使爆炸光。

For example, aluminum powders are preferred for glass surfaces and brass, whereas granulated jet black powder is used on silvery surfaces to create better contrast.

例如，铝是玻璃表面和黄铜首选，而粒状喷射黑用于银色表面以产生对比度。

The idea is to inject sulphur dioxide—or perhaps other chemicals such as calcium carbonate or powders made of aluminium or diamonds—not into the troposphere, but the stratosphere, which begins up to 20km above the surface.

这个想法是将硫酸盐——或者其他化学物质， 如碳酸钙或铝、钻石——注入到平流层而不是对流层，平流层从地表以上约20公里处开始。
