postannealing 中文意思是什麼
postannealing
解釋
焊後退火 焊後退火-
Due to high - thermal stability and independent of impurities dj - center is argued to originate from antisite or antisite complex. furthermore, the ltpl measurements have been taken on as - irradiated and postannealed p - type 6h - sjc, l ; lines related to dj - center were not observed with sample after postannealing at 1500 ?, the observation of a series of high intensity spectra which may mask the d1 - center due to the recombination of the d - a pairs
本文還對經幅照的p -型6h - sic的幅照退火特性進行了研究，在經過1500後退火的樣品中沒有觀察到d _ i - center ，這可能是由於d _ i - center被實驗中觀察到的源於d - a對輻射復合的高強度的譜峰所掩蓋。 -
Li lines related to di - center, which can be observed in all sic polytypes after various kinds of particle bombardments or irradiations and can withstand high - temperature annealing up to 1700 ?, were observed with the samples after postannealing above 700 ?
在700溫度退火后的樣品中觀察到d _ i - center ，該中心在幅照或粒子轟擊后的sic的各種多型體中都觀察到，並能經受高達1700溫度的退火。 -
In this article, low temperature photoluminescence measurements have been performed on as - irradiated and postannealed n - type 6h - sic, the postannealing temperature is up to 1650 ?. three sharp lines at 478 ^ 483. 3 and 486. 1nm respectively were observed for the first time in the as - irradiated samples and argued to be due to vacancy - like induced by irradiation
對經輻照后未退火的n型樣品的低溫光致發光實驗中，首次觀察到三條尖銳的譜線，分別位於478 . 6 、 483 . 3和486 . 1nm位置，該系列譜線可能與輻照誘生的點缺陷有關。
