莲子心化学成分及药理作用研究进展
Review on the Chemical Constituents and Bioactivities of Nelumbinis plumula
 [PDF]

秦宁,, 文祥
Journal of Microwave Chemistry (MC) , 2018, DOI: 10.12677/MC.2018.23010
Abstract:
莲子心为一味传统中药,具有清心安神,交通心肾,涩精止血的功效。其主要的化学成分为生物碱类和黄酮类,也含有多糖类、挥发油和微量元素等多种成分。因其具有良好的抗肿瘤、抗氧化、抑制肝纤维化、降血糖、抑菌抗炎和心血管保护等药理作用,使其近年来成为研究的热门。本文从莲子心的化学成分、药理作用、开发利用等方面,概述其研究现状,以期为其进一步的开发应用提供参考。
Nelumbinis plumula is a traditional Chinese medicine. It has the effect of clearing the heart and calming the nerves, communicating the heart and kidney, and stopping the bleeding. Its main chemical components are alkaloids and flavonoids, as well as polysaccharides, volatile oils and trace elements. Because of its good anti-tumor, anti-oxidation, inhibition of liver fibrosis, hypoglycemia, antibacterial and anti-inflammatory and cardiovascular protection, it has become a hot research in recent years. This article will summarize the research status of the chemical constituents, pharmacological effects, development and utilization of lotus seeds, in order to provide reference for further development and application.

生物钟的调控
Regulation of Circadian Clock
 [PDF]

秦宁,, 文祥
Interdisciplinary Science Letters (ISL) , 2018, DOI: 10.12677/ISL.2018.24018
Abstract:
生物钟在动物、植物等生物体内普遍存在,其对维持机体的行为、生理以及新陈代谢等方面起至关重要的作用。因此,本文结合2017年诺贝尔生理学或医学奖相关研究内容,从生物钟的定义及分类、生物钟运行的相关控制基因和生物钟异常引起的某些疾病及调节生物钟的航天牌眠尔康等四个方面进行概述。
The circadian clock is widespread in animals, plants, and other organisms, and it plays a crucial role in maintaining the body’s behavior, physiology, and metabolism. Therefore, based on the research contents of the 2017 Nobel Prize winners in physiology or medicine, this paper summarizes three aspects: The definition and classification of circadian clock, the related control genes that control the operation of circadian clock, and certain diseases caused by abnormal circadian clock.
露天矿生产计划的最优化

系统工程理论与实践 , 1985,
Abstract: 本文以著名的T.B.Johnson多周期生产计划模型为基础,论述了综合集合法、混合型问题的分解法、网络流和广义拉格朗日乘数调整法等算法。这是一种新的逼近解法,可以用来解决露天矿生产进度计划这个既大又难的问题。
黑河春末初夏径流量与气象要素的关系

高原气象 , 1988,
Abstract: 本文利用莺落峡水文站的水文资料和祁连气象站的气象资料,分析了春末初夏黑河流量与气象要素的关系。发现4月份流量主要取决于前期降雪、积雪量,其次是当月的气温高低;5,6月流量主要取决于5,6月降水量,其次是前期降雪、积雪量和5月份气温高低。这项工作的目的是为流量预报提供依据。
圆钢拉筋法起拱加固桥式吊车主梁

力学学报 , 1975, DOI: 10.6052/0459-1879-1975-1-1975-007
Abstract: 现代工厂桥式吊车大梁大都是箱形刚体,整个大梁体为塑性箱式梁结构。在吊装货物过程中,梁体受交变荷重的影响,使主梁拱度消失而变形,天车将被迫停产检修(起拱度、矫正梁体,有时还要加固)。以往起拱是采用火焰法,加固多用钢骨架焊结构,既费工,又费料,而且工期长,很不经济。为了及时、省工、省料地检修因主梁拱度消失而变形的天车,我们遵照毛主席关于“自力更生”的教导,组成了老工人、领导干部、工程技术人员的三结合班子,自己动手,采用圆钢拉筋法加固天车主梁的工艺,在我厂4天车(起重量10吨,跨距22米)大修上试验
土壤中的吸附态汞、全汞及其找矿意义

地质与勘探 , 1984,
Abstract: 汞作为地球化学勘查中具有较大潜力的远程指示元素,已逐步被人们所认识.近年来,国内外对土壤中汞的存在形式及找矿意义进行了不同程度的研究,本文就土壤中吸附态汞和全汞,作为两种找矿信息进行研究和探讨.初步研究了二者之间的关系以及寻找隐伏矿床的实际意义.
