Confusion between rheopectic and dilatant fluids(
https://en.wikipedia.org/wiki/Rheopecty)
An incorrect example often used to demonstrate rheopecty is cornstarch mixed with water, which resembles a very viscous, white fluid. It is a cheap and simple demonstrator, which can be picked up by hand as a near-solid, but flows easily when not under pressure. However, cornstarch in water is actually a dilatant fluid, since it does not show the time-dependent, shear-induced change required in order to be labeled rheopectic. These terms are often and easily confused since the terms are rarely used; a true rheopectic fluid would when shaken be liquid at first, becoming thicker as shaking continued.

@thesun1637大致举例,dilatant fluid之一是玉米淀粉糊,搅动越快越费劲;rheopectic fluid之一是某些润滑油,持续振动下会开始变黏稠。
