A quantum chemistry investigation on antimalarial mechanism of Qinghaosu based on cleavage of the peroxide bridge;

To ensure the project quality, one has start with the process control, especially the control of key process.

Study Methods: The key process of cellular LPBM was studied bymeans of comparison of the transition rate of.

QCOS(Quality Check Operation Sheet)is a quality operating tool from General Motors for critical process control which could help to detect the defect during critical manufacturing process and decrease the risk of the occurrence of the defect(including safety,regulation,all the key process like torque,weld,equipment,operators that directly impact the customer satisfaction).

This investigation was to determine the bonding process and bonding quality between gold ball and substrate by dynamic characteristics of impedance and power of PZT rings which was at the front of transducer system.

This article clearly discusses the logistic relations either pivotal process with key nature,important characteristic,key parts,important parts and key process by the terms and definitions of key processes,explores the differences between key processes and pivotal working procedure,explaines the activity between import and export of identifying of pivotal process,and activities related with them.
