根据我校国家级电工电子示范中心提出的“与兴趣相结合,以需求为导向,用问题作牵引,以能力培养为重点”的四项原则,针对模拟电子技术实验教学中出现的一些问题,结合自身的教学实践经验,本文就模拟电子技术实验教学在内容、方法和手段等方面提出教学改革的思路和做法.该教学方法和手段对培养学生的实际动手能力和创新意识起到了积极的促进作用.

Jiannan structure in west Hubei and east Sichuan has been found since 1970s-80s.In recent years,Southern Feisan Section has gradually become the main gas reservoir in gas-field exploitation with a deep development.Mainly tapping out the potential of developed fracture reservoir nearby Kuashimiao Fault and breaking through Feisan section reservoir in Kuashimiao footwall by rolling exploration can increase production in southern Feisan gas reservoir.

本文通过简易函数发生器的设计,介绍了集成运算放大器的非线性应用.并通过实例,给出了设计步骤,并详细分析了电路参数的选取.

Reservoir groups 1～3 on the lower segment of Jianxin-Tuoshi Xingouzui Formation in the east of Qianjiang depression Jianghan basin had all developed into tight sandstone lithologic trap with low porosity and low permeability.With the proceeding of exploration work in recent years,a batch of light oil reservoirs had been discovered in this area.Based on the study on the stratigraphic sequence and the characteristics of assemblage of source,reservoir,and capping rocks in Jianxin-Tuoshi district,this essay had made the most use of various shaft data obtained from geological survey,gas logging,well logging,oil testing and other techniques to draw up a comprehensive review of the reservoir features in the area and discuss the adoption of quantifying methods to assess the reservoir capacity.

This paper formulates such key points as the project of compound logging in carbonate rock gas zones of marine facies in Northeast Sichuan,selection of transducers,detection of ground pressure and the quantitative interpretation evaluation method for oil and gas show.It puts forward some understandings about improvement of the interpretation coincidence rate of gas zone logging,enlargement of carbonate content data application,improvement of shale rock density measurement and research of nuclear magnetic resonance mud logging in carbonate rock,thus providing helpful technical reference for the logging teams from different oilfields who are working in Northeast Sichuan.

本文对先EDA仿真再实际调试这种实验方法的优点进行了分析,总结了本校电工电子示范中心实验内容和实验方法的改革经验。

This paper,through the well logging and mud logging data of 30 wells drilled in Jianghan Basin,concludes the inter-salt layer non-sandstones reservoir characters and responses and summarizes their evaluation methods and work process,thus providing a basis for their oil-water comprehensive evaluations.

DTMF technology is applied to communication network extensively The paper introduced to use the kind of DTMF specialpurpose chip base on MT8880 which receive and transmit the chip to realize the simple data transmission among the computer It′s characteristic utilizes a I/O to simulate interface signal of MT8880 Design and regard 89C51 as controller this time and make use of MAX232 to realize flat to change electricity,in order to finishing the data communications of computer AT Meantme,MT8880 connects with 89C51,the hardware and software design of 89C51 connects with MAX232 are given

本文围绕如何培养学生的创新能力这个主题,介绍了我校电工电子实验教学的实践经验.
