ASME B31G是国际通用的评价腐蚀管线失效应力的标准,考虑到这种方法的保守性,以修正后的B31G模型作为研究腐蚀管线失效应力的基础,考虑管壁厚度、腐蚀速率、工作压力、缺陷深度等随机变量,构建腐蚀油气管线可靠性极限状态函数。然后,采用一次二阶矩法对腐蚀管线进行可靠性分析,得出管线的失效概率、可靠性指标以及剩余使用寿命。此外,为了更加规范的管理腐蚀管线,参照美国石油组织的相关规定,对不同失效概率的管线进行了等级划分。在最后的案例分析中,还讨论失效概率对不同变异系数对的敏感性,计算结果表明失效概率对管壁厚度

提出了工程结构可靠性分析的高阶矩方法。主要是基于数值逼近原理,以切比雪夫正交函数族{Tk(x)}做基,利用功能函数的高阶矩信息,通过计算功能函数概率密度函数的逼近表达式,然后根据工程结构可靠性的一般表达式来计算结构的失效概率,进行可靠性分析。通过经典分布函数的数值检验和结构构件失效概率的计算结果比较,表明了该方法在理论上的正确性和工程中的实用性。

The prevalence of the risk factors and the risk of cardiac failure are both increasing in China. This might be the consequence of the changes of the life conditions (emigration to the urban areas, changes in the diet and life style, lack of physical exercise, etc.). The wide range of clinical presentations of cardiac failure (acute or chronic) and of therapeutic approaches (medical or surgical) makes necessary the integration within the same structure of the various experts involved in the diagnosis and the treatment of cardiac diseases. Technologic and human resources required to offer all the options represent a multifaceted commitment which should be focused optimally in dedicated centers. In these centers, collaboration should replace competition between the medical and the surgical cardiac specialists. Development of team work should permit to optimize the cost efficacy of the treatments. Most of all, such a structure will facilitate the translation of innovative therapies between the research centers and clinical facilities.

Liver failure (LF) is defined as severe dysfunction in hepatic synthesis, detoxification, and metabolism induced by various etiologies. Clinical presentation of LF typically includes severe jaundice, coagulation disorder, hepatic encephalopathy, and ascites. LF can be classified into acute LF, acute-on-chronic LF (ACLF), and chronic LF. ACLF has been demonstrated as a distinct syndrome with unique clinical presentation and outcomes. The severity, curability, and reversibility of ACLF have attracted considerable attention. Remarkable developments in ACLF-related conception, diagnostic criteria, pathogenesis, and therapy have been achieved. However, this disease, especially its diagnostic criteria, remains controversial. In this paper, we systemically reviewed the current understanding of ACLF from its definition, etiology, pathophysiology, pathology, and clinical presentation to management by thoroughly comparing important findings between east and west countries, as well as those from other regions. We also discussed the controversies, challenges, and needs for future studies to promote the standardization and optimization of the diagnosis and treatment for ACLF.
