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.

浅谈技能大赛促进汽车专业教学改革和人才培养成效的探究

2020年12月,一场旨在发挥职业技能竞赛在促进技能人才培养、推动职业技能培训和弘扬工匠精神重要作用的中华人民共和国第一届职业技能大赛在广州举行。这场比赛是自新中国成立以来,举办的规格最高、项目最多、规模最大的全国性、综合性职业技能赛事。再次把职教界一直关注的"以赛促教,以赛促学,赛教融合,互相促教"理念以及促进汽车专业教学改革和人才培养成效相关的话题提升到新的关注度。本文将作者亲身的参赛经历和学校教改成效,分享如何在技能大赛背景下促进汽车专业教学改革和人才培养成效的探究,希望能抛砖引玉为汽车职教的发展提供参考和启发。     

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.

Experimental research on the mechanical properties of gypsum breccia with different water content

This paper deals with the influence of water content on the mechanical properties of gypsum breccia with different initial water contents. The experimental research was taken on the GDS (geotechnical digital systems) tri-axial experiment system by strain rate control. The mechanical properties,including stress-strain curves,peak deviator stress,relative residual strength,elastic modulus,Poisson's ratio,angle of internal friction and cohesion of gypsum breccia,were studied by experiment. The results showed t...
