Although the reduction in trophoblast cell viability induced by PDG was dose-dependent Fig. 2, no such effect could be detected following treatment with LPS at varying concentrations Fig. 2c.

PD G减少滋养层细胞活力的作用是呈剂量依赖性的如图2，但以不同浓度的LPS处理细胞时，我们并未发现其有减少细胞活力的作用。

Experiments were designed and conducted on spacecraft thermal coating to simulate an absorbed dose profile from synchronous altitude radiation by varying the energy of incident electrons and protons.

文章介绍了航天器的热控涂层试验，用改变入射质子和电子能量的办法，模拟同步轨道辐射环境。
