First, Golgi hardened the brain tissue with potassium bichromate to prevent cells from deforming during handling.

首先，高尔基体用重铬酸钾硬化脑组织，以防止细胞在处理过程中变形。

Incorporating potassium dichromate and alcohol into the aniline at various stages of the experimental process, he finally produced a deep purple solution.

他在实验过程的重铬酸钾和酒精加入苯胺中，最终制成了深紫色溶液。

Yeah, oh, I wanted to check the chemicals we used in the lab when we analysed those samples — was it potassium chromate and silver nitrate?

没错。对了，我想确认一下在实验室分析那些样品时使用的化学制剂，我们用的是铬酸钾和硝酸银，对吗？
