广西大学安全工程专业教学改革探讨

根据广西大学专业设置以及广西生产行业特点,将已有安全工程本科专业培养方案及培养模式进行修改,其中以石化、矿山、造纸及制糖四大培养模块来进行,每个模块专业必修课程都为原来的专业必修课程,在专业选修课程中分别设置石化、造纸及制糖主要工艺及设备课程,以便安全工程本科专业毕业生在工作中能更好地将安全专业知识融入进实际工作中,确保广西安全生产工作长期、有效进行.     

化工原理教学中突出工程思维的培养

化工原理是一门实践性、工程性很强的应用课程。教学实践中应注重培养学生的工程思维、工程意识、分析工程问题、解决工程问题的能力。本文从工程研究方法的角度探讨对学生工程思维的培养问题。

基坑支护中土压力主、被动区的互换分析

以太原市某工程为例，从实际的基坑设计中得出，基坑支护中土压力设计值一般都比实际值偏大；支护桩周围的土压力的主动区、被动区并不是一成不变的。提出用位移分析的土压力模型来区分实际工程中的主、被动区，而后进行土体受力定量的分析。     

理工科院校法学专业走出就业困境之策略探析

经过几年的扩招之后，各理工科院校培养出的法学专业毕业生已经开始陆续走向市场，从各理工科院校所统计的数据来看，法学专业毕业生的就业问题已显得十分突出。突出法学教育在理工科院校的专业特色，多方面强化学生的实践能力是理工科院校法学专业走出就业困境的必由之路。各理工科院校应理性地面对目前的艰难与困境，充分依据各自的资源来追求自己在法学教育上的比较优势。     

The <Emphasis Type="Italic">M</Emphasis>/<Emphasis Type="Italic">G</Emphasis>/∞ system revisited: finiteness,summability, long range dependence,and reverse engineering

We explore M/G/∞ systems ‘fed’ by Poissonian inflows with infinite arrival rates. Three processes – corresponding to the system's state, workload, and queue-size – are studied and analyzed. Closed form formulae characterizing the system's stationary structure and correlation structure are derived. And, the issues of queue finiteness, workload summability, and Long Range Dependence are investigated. We then turn to devise a ‘reverse engineering’ scheme for the design of the system's correlation structure. Namely: how to construct an M/G/∞ system with a pre-desired ‘target’ workload/queue auto-covariance function. The ‘reverse engineering’ scheme is applied to various examples, including ones with infinite queues and non-summable workloads.

Study on Ceramic Cutting by Plasma Arc

Engineering ceramics are typical difficult-to-machine materials because of high hardness and brittleness. PAC (Plasma Arc Cutting) is a very important thermal cutting process and has been successfully used in cutting stainless steel and other difficult-to-machine alloys. PAC‘s application in cutting ceramics, however, is still limited because the most ceramics are not good electronic conducts, and transferred plasma arc cannot be produced between cathode and work-piece. So we presented a method of plasma ...
