best way to measure the shrinkage? I noticed that some paper mentioned they
use a specific gravity meter. What is the "a specific gravity
meter"? Is there anyone who can tell me where can I buy this kind of gravity
meter? Can you recommend any simple method to measure the shrinkage? Or do
you think cross-section SEM to measure the film thickness is a good method

本科实验搞过。
