radiation belt 中文意思是什麼
radiation belt
解釋
范艾倫輻射帶-
Van allen radiation belt
范艾倫輻射帶 -
At present, the solar cells used on space aircrafts are still mainly si and gaas solar cells. however, the radiation resistance ability of these two materials is poor. since the photoelectric conversion efficiency attenuates rapidly with the radiation, the lifetime of si and gaas solar cells is short and their stability is not satisfied for space applications at van allen belt
目前國內外用於航天器上的太陽電池主要為si和gaas太陽電池，但這兩種材料的抗輻射能力較差，其光電轉換效率由於高空輻射衰減很快，因而壽命短，穩定性差，不能滿足用於vanallen強輻射帶的空間應用需要。 -
According to the characteristic transformation of the eme in the process of its deformation, the stress concentration belt engendered by the coal wedge of the protective coat can be ascertained and the electromagnetic radiation measured result is consistence with the calculation result of the site survey materials
根據煤體變形破裂過程中產生的電磁輻射信號特徵變化，確定了保護層采空區煤柱產生的應力集中帶，電磁輻射測定結果與現場勘測資料計算結果相吻合。 -
Artificial radiation belt
人工輻射帶 -
The result indicates there is a correspondent relation between the eme and distribution of the stress state in the stress concentration belt, it is an innovation to ascertain the solid coal smear zone with electromagnetic radiation monitor technology to get the stress concentration belt engendered by the coal wedge of the protective coat
結果表明：電磁輻射信號與應力集中帶應力狀態分佈有較好的對應關系，可以電磁輻射監測技術確定保護層采空區煤柱產生的應力集中帶，是確定煤柱影響帶的一種新方法。 -
