薄膜弹性模量的估算

武汉理工大学学报 , 1997,
Abstract: ?在通常用来测量膜弹性模量的方法都不宜采用的情况下,本文提出一种将镀膜件视为特殊层合薄板,通过其弯曲时挠度与载荷间的关系来估算薄膜弹性模量的方法。文中首先理论推导了由两种材料层合的薄板弯曲时的挠度与载荷间的关系,然后利用镀sno2膜的玻璃试件在精细的弯曲实验下的挠曲线,估算得到sno2膜的弹性模量。
碳纤维混凝土电热红外无损检测的灵敏性分析

武汉理工大学学报 , 2005,
Abstract: ?利用碳纤维混凝土的电热效应,在电致发热的情况下,对含预制裂纹的碳纤维混凝土缺陷体进行红外无损检测,检测的灵敏性在于缺陷体被检表面上的最大温差。在建立了有内热源的热传导理论分析模型的基础上,采用有限元的方法计算得到了电热碳纤维混凝土缺陷体的表面温度分布及其最大温差,分析表明随材料电阻率的降低和裂纹逐步加深,检测灵敏性显著提高,为优化和评估电热红外检测方案提供了重要的数值依据。
冻藏温度对冷冻水饺肉馅品质和微观结构的影响

- , 2016, DOI: 10.13982/j.mfst.1673-9078.2016.9.034
Abstract: 本文研究了不同冻藏温度对冷冻水饺肉馅品质及微观结构的影响,以揭示冷冻水饺肉馅品质变化的机理。将水饺在-25 ℃冷冻后分别在-7 ℃、-18 ℃和-7 ℃/-18 ℃条件下冻藏0 d、30 d、60 d、90 d和180 d,每隔30d测定水饺肉馅的a*值和b*值,肉馅中肌原纤维蛋白凝胶性、水饺肉馅的扫描电镜及石蜡切片。结果表明,随着冻藏时间延长,水饺肉馅的a*值和b*值显著下降(p<0.05),肌原纤维蛋白凝胶的储能模量峰值随着冻藏时间延长而下降,Tanδ尾部值增加;扫描电镜和石蜡切片结果显示-18 ℃冻藏的样品组织比较细腻,肉粒基质蛋白变性程度较低,而-7 ℃样品和-7/-18 ℃样品的组织结构变得更粗糙,肉粒基质蛋白变性程度增加,肉粒基质蛋白乳化性下降,“渗油”现象明显,说明较高温度(-7 ℃)及变温贮藏(-7/-18 ℃)引起水饺品质劣变程度增加。因此,有必要将冷冻水饺在零售、运输、贮藏环节中保持低温短时贮藏,以保证冷冻水饺的品质。
The effect of different frozen storage temperatures on quality properties and microstructures of frozen pork dumpling fillings to reveal the mechanism underlying the changes in their quality was evaluated. Freshly prepared dumplings were frozen at -25 ℃ and then stored for 0 d, 30 d, 60 d, 90 d, or 180 d at -7 ℃, -18 ℃, and a temperature fluctuating between -7 ℃ and -18 ℃, respectively. The a*-value, b*-value, and the gel properties of myofibrillar protein were measured at an interval of 30 d, and the scanning electron microscopy (SEM) and paraffin sectioning of the dumpling filling were also performed. The results showed that with increasing frozen storage time, a*-value and b*-value of the dumpling filling was reduced significantly (p<0.05), the first peak storage modulus values (G′) of myofibrillar protein gel decreased, and Tanδ at the final heating stage increased. The SEM and paraffin section results indicated that the samples stored at -18 ℃ had a relatively fine and smooth texture, showing a lower degree of protein denaturation in the minced meat matrix. However, the texture of the samples stored at -7 ℃ and -7 ℃/-18 ℃ became coarse; the degree of protein denaturation and the emulsifying properties of the minced meat matrix increased and decreased, respectively; and there was a significant fat exudation. This finding indicated that a high (-7 ℃) storage temperature and a fluctuating storage temperature (-7 ℃/-18 ℃) caused deterioration of the dumpling quality. Therefore, a low-temperature and a short-term storage are necessary for the retail sales, transportation, and storage of frozen dumplings, in order to maintain a good quality.
体育强国的理论框架与顶层设计——从“十九大”报告中的国家大战略思考体育发展战略
Theory Framework and Top Level Design of a Sports Power: Thinking of Sports Development Strategy from the National Big Strategy in Report on the 19th National Congress of CPC


- , 2018, DOI: 10.19582/j.cnki.11-3785/g8.2018.01.002
Abstract: 摘要:运用文献资料调研和比较法,探讨体育强国的理论框架,从战略目标、战略途径与战略手段上,尝试进行体育强国的顶层设计。“十九大”报告描述了国家大战略,为中国体育未来发展明确了战略位置。加快建设体育强国,要求运用战略思维,转变体育发展方式,实现体育发展战略从重点发展到全面发展、从抓住机遇到创造机遇、从被动适应到主动塑造环境的战略转型。本文从体育综合实力的5个实力要素出发,构建了体育强国的理论框架。“体育强国”战略是体育界最高层次的战略,是体育战略的总目标,它统筹着全民健身战略、“奥运争光”战略、体育产业战略、体育科教战略、体育文化战略这5个子战略。体育强国的整个战略设计,是一个根据形势发展变化,需要不断进行调整、优化,以确保动态平衡的过程。
Abstract: By using the method of literature review and comparison, this paper discussed the theoretical framework of sports power, and tried to design top-level sports power from strategic objectives, strategic approaches and strategic means. The report on the 19th National Congress of CPC described the national strategies and cleared the strategic position for the future development of China's sports. To speed up the construction of a sports power, we need to apply strategic thinking and transform the way of sports development, so as to realize the strategic transformation of sports development strategy from key to all-round development, from grasping opportunities to creating opportunities, from passive adaptation to active shaping of environment. This study constructed the theoretical framework of a sports power from five factors of sports comprehensive strength. The strategy of "sports power" is the highest level strategy of sports industry, and it is the general goal of sports strategy. It coordinates the national fitness strategy, the strategy of winning the Olympic Games, the sports industry strategy, the sports science and education strategy and the sports culture strategy. The whole strategic design of a sports power is a process that needs to be constantly adjusted and optimized to ensure dynamic balance according to the development of the situation

增值税转型背景下的企业纳税筹划
(博士)
财会月刊 , 2009,
Abstract:   一、增值税转型改革方案  1.固定资产方面。我国此次增值税转型改革方案为:自2009年1月1日起,在维持现行增值税税率不变的前提下,允许全国范围内(不分地区和行业)的所有增值税一般纳税人抵扣其新购进设备所含的进项税额,未抵扣完的进项税额结转下期继续抵扣。此项改革方案实施后,在节税效应的影响下,企业将有更充足的动力构建基础设施、改善生产条件、提高经营水平、增强竞争力。同时,大量基础设施的构建导致固定资产的市场需求增加,从而拉动制造型企业的发展,对于刺激经济、促进就业等有着积极作用。
