[交流] 【求助】求翻译一小段~~

The hydroxyl region was observed on samples made into self-supporting wafers of around 20 mg/ cm2 and previously submitted to a thermal treatment under vacuum at 200 °C for 5 h. Si solid-stateNMRwas performed on a Bruker DSX-300 spectrometer operating at 59.63 MHz by use of cross-polarization from proton. The contact time was 5 ms, the recycle delay 1 s, and the spinning rate 10 kHz. 谢谢~~刚读文献不久不太明白~·有些单词词组翻译不出来~·

其实最难读的就是第一句，因为整个这个一长串“made into self-supporting wafers of around 20 mg/ cm2 and previously submitted to a thermal treatment under vacuum at 200 °C for 5 h”其实只是“samples”的修饰语，
