- 本文介紹車用發動機可變進氣管長度電子控制原理,並舉出了在奧迪VS(2.8升)發動機、歐寶Astra(1.8升)發動機上的應用實例。The principle of electronically controlled variable intake manifold length of vehicle engine is introduced in this paper. The application of this system to Audi V8(2. 8L) engine and Opel Astra(1. 8L)engine are made.
- 羅哌卡因(Ropivacaine,R)是一種新型長效醯胺類局部麻醉藥,由瑞典阿斯特拉疼痛控制中心(Astra Pain Control AB,Sweden)研製開發。Ropivacaine is a long-acting amino amide class of local anesthetics, developed by Astra Pain Control AB, Sweden .
- 在熱重分析儀上以異丙苯裂化反應為模型反應 ,採用CCAP(恆碳Arrhenius關係圖 )技術探討了裂化催化劑ASTRA MB1的積炭失活機理 ,得到了反應速率常數和有效擴散係數隨積炭量的變化規律。This work is to investigate the deactivation of cracking catalyst during coking by using CCAP(Constant coke Arrhenius plots) technique. Cumene cracking on ASTRA MB1 zeolite was chosen as a model reaction. The thermogravimetric analyzer(TGA) was used as a continuous flow reactor to monitor coke levels.
