By extracting water from the detector's chamber, the detector surface becomes a concave hemisphere.
通过从检测器的舱室获取水分，检测器表面成为凹半球。

(Injecting water back returns the detector to a flat surface.) Injecting water into the chamber of the lens makes the thin membrane become a convex hemisphere.
(给舱室注射水使检测器表面回复平坦)注射水进入透镜舱室使得薄膜变成凹半球。
