Investigation on Instruction and Safety Operation in the "Numerical Control CAM and Operation";

PID instruction and its application research ——Based on design and research of single-chip PLC;

Anti tracking technology of the converse instructions and the prefetch instruction queue;

Analysis of DA A Directive in MCS-51 Systerm;

Based on the summary of enacted and implemented quality criteria and emission criteria in the system of EC atmosphere environment standard, the implementation procedures and requirements to member states and characteristics of EC atmosphere environment standard directives are analysed, and some suggestion for formulating and implementing Chinese atmosphere environment standard is also proposed.

Medical devices standards system in EU is composed of directive,harmonized standards and conformity assessment procedures.

This paper induced and compared the numerical controlling system's programing instructions in common use to improve programming techniques,and expounded the safe operation essentials of machine too

It is very close to hardware and has complicated programming structure as well as numerous instructions.

Aimed at low execution efficiency and bad transplantation of the system which uses the explanatory mode to execute its instructions,especially when some programs are complicated,a method of constructing a compiled PLC system instruction based on ARM was proposed.

The Integration of ROHS and WEEE Order and ISO14001 Enviornment Management System;

The composition,application,basic order,feature and development tendency of CVMID programmable controller that is made by Omron Co.

Maple Software is very powerful in the field of calculus,in this paper,only some of the orders and Right-functional in the Integration s Application are discussed.
