江汉平原印支期以来的盆山耦合关系及下古生界油气响应

利用构造地质学和油气系统理论，以盆地构造-沉积分析技术为手段，研究了印支期以来江汉平原与周缘造山带的耦合关系，探讨了江汉平原的构造演化及其对油气成藏的控制作用。印支期以来江汉平原及周缘经历了挤压、拉张、挤压3次大的构造应力场的转换，使古生代海相碳酸盐岩沉积为主的盆地具有改造盆地的特点；一方面强烈的抬升、剥蚀使早期聚集的油气经历改造和再分配、再聚集过程，另一方面燕山期构造活动使逆冲推覆构造成为该区重要勘探领域。综合分析表明，位于台、盆转换带的宜昌-珂理-簰州区带是目前江汉平原及周缘下古生界油气勘探的有利地区。     

Development of an undergraduate course – Internet-based instrumentation and control

The objective, strategy, and implementation details of a new undergraduate course, Internet-based Instrumentation and Control, are presented. The course has a companion laboratory that is supported by the National Science Foundation and industry. The combination is offered to senior-level undergraduate engineering students interested in sensing, instrumentation, control, and web programming that want to learn more about the integration of these technologies for solving real-world engineering problems. The course will also be offered to gifted high school seniors with similar interests and can serve as a vehicle to attract them to engineering disciplines. Preliminary assessment of the first offering of the course is encouraging and has shown that the course has achieved success in helping students understand concepts and master basic technologies for developing Internet-based automatic systems.     

Study on axiomatic rules for building up relationships between requirement and source programs

The purpose of our study is to build up relationships between requirement and source programs with our originally thought-out rules. When other rules to be derived from these original rules are applied to software development, even a single instruction in a programming language could be determined, and the program would satisfy the requirement. More specifically speaking, these rules will turn into a formula or a prototype of software programs. Hence, when the variables in the requirement are placed in the formula, we can get a required program in an automatic way.

An investigation of the relation between the temperature dependences of the initial unbalance and the output signal of resistance strain sensor bridge circuits

The relation between the initial unbalance and the output signal of bridge circuits when acted upon simultaneously by the physical factor being measured and the temperature of the surroundings when the bridge is supplied from a voltage or current source is investigated. Analytic relations are obtained which explain the temperature dependence of the useful output voltage under external physical action. __________ Translated from Izmeritel’naya Tekhnika, No. 1, pp. 48–49, 2007.

试论安定性不合格消石灰对柔性路面质量的影响

由于过烧石灰的存在和消解不当等原因，造成消石灰安定性不合格，当石灰稳定类路面结构成型或投入使用后，消石灰中的生石灰颗粒开始吸收周围水分，慢慢消解，消解过程中发生体积膨胀，对路面产生破坏。解决石灰安定性问题对防止公路前修后坏，延长路面使用寿命具有积极的现实意义。
