v-p ratio 解釋
通氣-灌注比率
  • v :
  • p :
  • ratio : n. (pl. ratios)1. 比,比率,比值;比例;系數。2. 【經濟學】復本位制中金銀的法定比價。vt. 1. 用比例方式表達;求出…的比值;使…成比例。2. 將(相片)按比例放大或縮小。
  1. Steamed millets with water content of 45 % ( broomcorn ) and 42 % ( foxtail ) were inoculated with liquid culture of p. delphacis ( containing mycelial mass of ~ 25 mg / ml ) at a ratio of 20 % ( v / w ) and then incubated at 25 ? and l : d 12 : 12

    將菌絲生物量約為25mg / ml的菌絲液按20的比例( v / w )接入經高溫濕熱滅菌並適度熟化、含水量分別為45和42的黍米及粟米中,在25和12l : 12d條件下直接培養,所獲3 17d黍米和粟米培養物的產孢潛能和有效產孢時間因培養天數不同而異。
  2. Then we grew the material with different active layer growth temperature, different v / ratio, different doping concentration and form. after that, we tested these materials by photoluminescence ( pl ) technology, and got the best growth condition according to the results of photoluminescence spectra. our result was that the active layer growth temperature was 700, v / ratio was 60, waveguide layer doping was gradual changed ( n - type doping with sih4 from 190sccm to 590sccm, p - type doping with dmzn from 90sccm to 490sccm )

    然後在不同的有源區生長溫度、 /比、摻雜方式及濃度情況下對激光器材料進行外延生長,並利用光熒光( pl )技術對不同生長條件下外延材料的光致發光特性進行了測試對比,結果表明在下列條件下生長出來的材料具有更好的光學和電學性能:有源區生長溫度在700 、波導層/比選擇為60 、 n型波導漸變摻雜190sccm - 590sccm的sih _ 4 、 p型波導漸變摻雜90sccm - 490sccm的dmzn 。
