For attaining this it was necessary that monitoring rial quality and adjusting to silicon-copper mass in the reaction process.
为达到此目的，监测原材料的质量和调整反应过程中硅铜触体是必需的。

Photovoltaic cells rely on amorphous or crystalline silicon, cadmium telluride, or copper indium selenide and sulfide.
光伏电池依赖于非晶态或晶态的硅，碲化镉或者硒化、硫化铜铟。

Alloy steel owe their properties to the presence of one or more elements other than carbon, namely nickel, chromium, manganese, molybdenum, tungsten, silicon, vanadium, and copper.
