概况成立时间:1979年主要产品:MG牛皮纸、生活用纸等注册办公室:孟买1运营与人力管理疫情之前我们的新工厂正在安装和调试中,所有项目工作进展顺利。疫情之后新的制造工厂的所有安装和调试工作一直顺利进行,但是疫情发生后,直到2020年3月的第三周开始,政府突然宣布全国范围内的封锁令,致使整个工厂安装与调试工作脱轨。由于建筑工地缺乏熟练劳动力,本来预计将于2020年4月底投产的工厂延期至2020年7月才投入运营,多花了两个多月的时间,而且直到2020年9月,全部经营管理人员才到位。

This study investigated the mechanical properties and microstructural characteristics of fiberboard composite produced by naturally-bonded Malaysian bamboo fiber(Bambusa vulgaris).The components that obtained through soda pulping of bamboo culms such as fiber and black liquor,were used for the preparation of high-density fibreboard composite at two target densities of 850 and 950 kg/m^(3).The bamboo fiberboard composite(BFC)were then produced at 200°C and two pressing parameters of 125 and 175 s/*** mechanical properties,e.g.,flexural strength and internal bonding(IB)of BFC samples were evaluated according to BS EN 310:1993 and BS EN 319:1993,*** was found that the mechanical performance of the composite with 850 kg/m^(3)density was significantly higher than 950 kg/m^(3)ones,especially for the samples with 125 s/mm pressing *** characteristic of the BFC samples illustrated that the fiber linkages were cracked in the composites with higher density,e.g.,the composite with the density of 950 kg/m^(3)and also black liquor were slightly degraded at longer pressing time,which led to the reduction in mechanical properties,especially in IB strength.

We report high-temperature thermodynamics for fcc silver by combining ab initio phonon dynamics to empirical qua.r.tic temperature-dependent term for anharmonic part of Helmholtz free energy. The electronic free energy is added through an interpolation scheme, which connects ambient condition free electron gas model to Thomas-Fermi *** present study shows good a.r.ement with experimental and reported findings for several thermal properties, and the discrepancy observed in some caloric properties is addressed. The decreases in the product of volume thermal expansion coefficient and isothermal bulk modulus and in the constant volume anharmonic lattice specific heat at high temperature are the clear evidences of proper account of anharmonicity. The present study also reveals that T-2-dependent anharmonic free energy is sufficient for correct evaluation of thermal pressure and conventional Grüneisen parameter. We observe that the intrinsic phonon anharmonicity starts dominating above characteristic temperature, which is attributed to higher order anharmonicity and can be related to higher order potential derivatives. We conclude that the uncorrelated and largeamplitude lattice vibrations at high temperature raise dominating intrinsic thermal stress mechanism, which surpasses the phonon-anharmonism and requires future consideration.

改革开放四十余年以来,快速变迁的社会环境对中国社会的文化心理产生了深远影响,中国社会对“何为幸福”的认知也经历着时代变迁。文章首先通过梳理相关文献和采用深度访谈方法,提炼出兼具民族特色和时代特征的五大幸福观维度——“物质满足”“人际支持”“自我实现”“自然和谐”和“家国情怀”。在此基础上,文章基于1979-2021年《人民日报》上的新闻文本数据,采用词嵌入(word embeddings)技术(一种刻画词汇间语义关联的机器学习方法)刻画中国幸福观的历史演变。结果发现,对于“何为幸福”这一问题,“自我实现”的重要性呈上升趋势,以“家国情怀”为中心的传统幸福理念也逐渐得到巩固;自千禧年以来,“物质满足”基础幸福观维度整体式微,“自然和谐”幸福观维度的地位迎来了社会的重视。通过构建幸福变化指数发现,近40年来五个历史时期(1982-1984年、1991-1993年、2000-2002年、2013-2014年、2017-2018年)里的经济社会变动对中国幸福观的变化产生了较大影响。文章不仅从横向(研究范式)与纵向(跨时段视角)拓展了社会文化心理的相关研究,而且对构建国民幸福指标体系和发展幸福产业具有指导意义。
