14、formation 網(wǎng)格變形Worki ng dista nee 工作距離mm175The Tele-microscopy system has been designed with the aim of performing successive erosion measurements during GIE tests with no need of re-opening the vacuum chamber. This greatly reduces the risk of contamination and saves a considerable amount of time if

15、multiple measureme nts are to be take n along an en dura nee test. The remarkable adva ntage of perform ing a series of successive measurements lies in the opportunity of recording not only the total erosion after a certain number of firing hours, but also a time-history of the erosion (thus providi
