Microprocessor-based data acquisition system for respiratory signals

Microprocessors are having an increasing role in online measurements in the medical field instead of large computers because of their compactness, low cost and ease of operation. This paper describes a microprocessor-based data acquisition system representing the primary stage in designing a larger online acquisition and processing system for measurement and correlation of respiratory signals. The system designed has the features of easy communication, flexibility of operation and system's software and hardware. The system uses a mass storage unit for permanent data storage. A detailed discussion of the hardware and software is presented.     

Linking assembly code to PASCAL programs for microprocessors

High level languages used for programming microprocessors still need some assembly code to cover all the programming requirements and aspects. Using assembly code in a high level language program introduces certain difficulties and disadvantages. Practical suggestions to minimise the use of assembly code procedures in a high level language program is presented. (The high level language discussed is pascal/64000.)     

缅甸蒙育瓦铜矿床——晚中新世浅成热液体系中的一种斑岩全国矿床

蒙育瓦铜矿区由4个矿床组成,为东南亚第二大铜矿.文章在分析总结该矿区区域构造、矿化围岩、地层年代、成矿模式的基础上,认为该区矿化作用是由岩浆源SO2气体从安山斑岩岩脉底部的结晶熔体中上升,与下渗的大气水相互反应凝结形成.这种岩浆与上升的变质水以及向东俯冲过程中的印度洋壳板块在缅甸板块下方的部分熔融有关.推断出在蒙育瓦矿床的下部可能存在一个隐伏斑岩铜矿.     

Microprocessor teaching

The importance of microprocessor education when applied to physics students and the need for incorporation of software in new automated equipment is realized. Experience of developing and applying a programme, which is based on practical knowledge gained from lecture courses, for such an education is reported. Much of the programme has been directed towards the use of microprocessor-based equipment, since such a need is being realized with new equipment arriving in this part of the world. The programme facilities, course contents and laboratory experiments are also explained.
