当前,基于能源战略的考虑,国内液化天然气(LNG)项目的建设风生水起。因LNG的用户价格等于LNG进口价格加上气化管输费,LNG进口价格完全由国际市场决定,而气化管输费的大小直接取决于LNG项目的建设成本和运营维护成本。文章首先介绍了项... 详细信息

当前,基于能源战略的考虑,国内液化天然气(LNG)项目的建设风生水起。因LNG的用户价格等于LNG进口价格加上气化管输费,LNG进口价格完全由国际市场决定,而气化管输费的大小直接取决于LNG项目的建设成本和运营维护成本。文章首先介绍了项目全寿命周期费用管理的理论以及LNG行业的建设情况和特点,着重介绍了项目全寿命周期费用管理理论在LNG项目建设不同阶段的应用,并提出了在项目的不同阶段如何使用该理论,才能真正达到全寿命周期费用最低,从而使气化管输费降至最低。

Type 2 diabetes(T2D)is a disease characterized by heterogeneously progressive loss of isletβcell insulin secretion usually occurring after the presence of insulin resistance(IR)and it is one component of metabolic syndrome(MS),and we named it metabolic dysfunction syndrome(MDS).The pathogenesis of T2D is not fully understood,with IR andβcell dysfunction playing central roles in its ***,hyperglycemia,along with other metabolic disorders,results in IR and/or isletβcell dysfunction via some shared pathways,such as inflammation,endoplasmic reticulum stress(ERS),oxidative stress,and ectopic lipid *** is currently no cure for T2D,but it can be prevented or in remission by lifestyle intervention and/or some *** prevention fails,holistic and personalized management should be taken as soon as possible through timely detection and diagnosis,considering target organ protection,comorbidities,treatment goals,and other factors in reality.T2D is often accompanied by other components of MDS,such as preobesity/obesity,metabolic dysfunction associated steatotic liver disease,dyslipidemia,which usually occurs before it,and they are considered as the upstream diseases of *** is more appropriate to call“diabetic complications”as“MDS-related target organ damage(TOD)”,since their development involves not only hyperglycemia but also other metabolic disorders of MDS,promoting an up-to-date management *** this review,we aim to summarize the underlying mechanism,screening,diagnosis,prevention,and treatment of T2D,especially regarding the personalized selection of hypoglycemic agents and holistic management based on the concept of“MDS-related TOD”.

采用有限元数值分析方法,对门式钢刚架在多参数影响下的抗火性能进行了研究。基于经典结构力学,建立非均匀温度场中单跨门式钢刚架结构的内力方程,以此判断高温下,结构最不利截面几何位置。研究表明,在大空间建筑火灾中,主要是梁跨中截面和梁端截面影响门式钢刚架结构抗火承载力;根据数值分析结果,建立不同温度场非均匀性、荷载比、高跨比和楔率参数条件下门式钢刚架结构临界温度的大数据库,并拟合得到各参数影响下结构的临界温度经验公式,在临界温度法框架下,建议了单跨门式钢刚架结构抗火设计实用方法,为基于计算的门式钢刚架结构在大空间建筑火灾下的抗火性能评估提供了参考。
