例句

Matches characters that combine an uppercase letter with a lowercase letter, such as nj and dz

匹配將大寫字母和小寫字母結合的字元，例如， nj和dz 。
Then, the effect of heavily doped boron on ig of czochralski silicon was also investigated. it is found that no dz ( denuded zones ) were observed in the hb samples subjected to high one - step temperature, ramping annealing respectively. for conventional high - low - high three - step ig annealing, the dz becomes narrower and bmd density is higher in hb samples than that in lb samples, as a result of hb enhancing oxygen precipitation

結果顯示，單步高溫熱處理時重摻硼樣品不能形成潔凈區；降溫退火中，降溫速度較為緩慢（ 3 / min ）時能生成一定量的氧沉澱，但沒有潔凈區形成；普通高?低?高三步熱處理過程中，形成明顯的潔凈區，但相對輕摻樣品而言，潔凈區較窄，氧沉澱密度明顯偏高，說明重摻硼樣品吸雜能力強。
A modified ig process was suggested, through which a wider denuded - zone ( dz ) on the surface of wafers and higher density of oxygen precipitation in silicon bulk were obtained

使用改進的內吸除工藝，在重摻砷矽片表面形成了較寬的清潔區，體內形成了較高密度的氧沉澱和誘生缺陷。
Based on a study of the quality problem that exists in sample analysis for 27 projects of regional geochemical survey, the author holds that the unsatisfactory analytical quality is mainly attributed to loose understanding and implementation of the quality control and quality monitoring stipulated in dz / t0167 - 95 standard

摘要通過對27個區域地球化學調查項目中出現的樣品測試質量問題的研究，認為質量不高的主要原因是對dz / t0167 - 95規范中規定的有關質量管理、質量監控的錯誤理解和執行不嚴所致。
