shifting low？correlation?（E--C关于PE）？ 1. fluidized bed density band narrowing and shifting low --- ”流化床密度值范围变窄并下降”不好理解，比如原来上下层密度相差0.05，现成相差0.01，相差变窄。但这个shifting low --- “下降”如何理解， shifting low 修饰bed density还是density band ？ 2. 关于noise，相关内容如下，改为“ 干扰 ”好点吧。 since a chunck is a large fixed density object, the noise normally present in the density readings will diminish when a chunck is in the reactor.

请大家帮我翻译一句话（汉译英），谢谢？ the most important factor to restrict the full capacity production of device and long-term operation is reactor scaling. 个人见解，坐等高手纠正。 查看更多
