全挂车轮转向装置设计

全挂车转向装置分为轴转向和轮转向两种形式，由于轮转向两种形式。由于轮转向装置转向角度小，制造工艺复杂。成本高，一般较少应用。便全挂车采用轮转向装置可降低车厢地板高度，且其机动性较轴转向全挂列车好，推导了轮转向传动连杆机构的解析关系式及优化设计目标函数和约束条件，并给出了相应算例。

燃气轮机监测系统的建模与实现

以从法国引进的ＭＳ６００１燃气轮机发电机组为研究对象,针对它开发了一套以燃气轮机循环计算、压气机和涡轮特性计算及燃气轮机变工况计算为基础的工况监测显示系统软件。该软件的开发有利于提高燃气轮机系统运行的管理水平,为全面实现燃气轮机机组的智能监测和诊断打下坚实的基础。     

The ABC Catering Services Ltd.——ABC食品供应服务公司

ABC Catering Services Ltd. has long recognized its needs to compete effectively in its key markets in the Pacific Rim. With ABC′s historical focus on delivering almost faultless service, comparatively little attention has been given to the supply chain cost of that delivery. However, the new kitchen at Seoul, wasoPen in 1997, added more workload to the company. Things have not been working well since then. The ABC Corporation realizes that it is necessary to reduce supply chain costs and to improve its operation efficiencY in order to retain and expand customer bane.

瞬变电磁法在隧道工程中的应用

文章简述了在复杂地形条件下、在隧道施工前和过程中,为了规避施工风险和预防施工过程中可能出现的地质灾害,运用瞬变电磁法勘察含水(泥)的断层、岩溶等水文地质问题;探讨了瞬变电磁法的理论基础、野外工作方法及资料处理.研究表明,瞬变电磁法勘探与其它常规电法相比,有许多突出的优点,可在复杂地形条件下工作,有良好的空间分辨性.实例中对瞬变电磁法勘察原理、工程实践和勘察效果作了详细介绍.     

Public Perception of Ocean Governance and Marine Resources Management in Taiwan

Understanding public perception of the oceans, and relationship between society and the sea is an important key to the sustainable management of marine resources. This research reports the first population-based survey on Taiwanese public knowledge, attitudes, and actions on marine-related issues. The stratified random sampling by county was completed with 1,120 telephone respondents from October to December 2010. More than 60% of the respondents have heard about global warming, sea-level rising, the Gulf of Mexico oil spill, the coral reef bleaching crisis, and Japan whaling fisheries. However, less than 20% of the respondents are aware of Taiwanese domestic marine policies, such as the Ocean White Paper. On resources conservation, 74.7% of the respondents support the bluefin tuna catches regulations and 76.6% agree that the shark fin fisheries will impact shark resources. Education and age are the major affecting variables for resource conservation and knowledge. Higher education and age 40–49 are most supportive of conservation measures. For marine recreational activities, 42.2% of the respondents can swim, and 44.2% of the respondents had not visited the beach in the previous year. The results suggest that the government could establish a specialized agency to strengthen its marine policy and take more actions to protect ocean environment and conserve marine resources. To encourage more Taiwanese to participate in ocean recreational activities, the government could build a safe facility for marine recreation, cooperate with the private sectors in education, and provide outreach to raise public awareness of the oceans.
