相对密度英文

Relative density.

Ah, I remember a time back in college when I was studying fluid dynamics. I was in a lab, and we were measuring the relative density of some chemicals. It was a sunny afternoon in May, and the lab was bustling with students. We had this big glass cylinder filled with water, and we were carefully adding small amounts of a new chemical to it. The temperature was around 22 degrees Celsius, and we were using a hydrometer to measure the density.
I suddenly thought, "What's the English term for 'relative density'?" It's a term we use often in scientific contexts. So, the answer is "specific gravity." It's a measure of the density of a substance compared to the density of water at a certain temperature. Now, what's the significance of relative density in everyday life? Hmm, maybe I'll find out next time I'm cooking.

相对密度这个词在英文里叫做 "specific gravity"。它是一个物质相对于水的密度比值，用来描述物质的密度。简单来说，就是用来比较不同物质密度的一个指标。
