special code
3.Based on one-dimensional Method of Characteristics (MOC), a numericalmodel of pressure-wave progation if presented in this paper. A special code isprogrammed to analyze and calculate waterhammer resulted from rapid opening orclosing of valve in the experimental sodium loop of Fast Breeder Reactor (FBR).
4.According to the characteristic of DMU 70V machining center, this thesis deals with the procedure after configuring its special-postprocessor, and the code (G-code) generated in Pro/Engineer system, which can be used in this machining center directly.
6.For overcoming this problem in software design and implementation, Aspect-Oriented Programming (AOP) is put forward to modularize the crosscutting concerns by a special unit, it decouples function code and other code, and on a higher-leve1 of abstraction and decomposition, it improves maintainability, reusability and extendibility of software further.
9.In this paper,an automatic data processing system based on RS232 C serial port and GPIB parallel port communication at the same time is designed and implemented with object oriented programming design language,Visual Basic 5.0,and a special problem about conveying ASCII code for programmable instruments command words in Visual Basic 5.0 and higher version is discussed and solved.
