INTRODUCTION Human limbs are complex, delicate systems.Their reconstruction, both for appearance and forfunction compensations, proves to be complicatedprojects. With the development of science and tech-nology, both researchers and disabilities hope to haveartificial limb much more perky, comfortable, dex-terous and effective. Although thousands of pros-thetic limbs are commercially available worldwide,most of them, from mechanical styles to electricstyles, from motion controlled t… 相似文献

INTRODUCTION Saccharomycete, closely linked with human life, is the only microbe that has been utilized to the extent of over a million tons in the world, and is one of the modelled biological bacteria mostly used in modern genetic engineering. Since there are no effective online instruments for measuring the production or resultant concentration, which is a very important quality index in fermentation process, soft sensors (Martin, 1997; Tham et al., 1991; Assis and Filho, 2000; Salgad… 相似文献

Brix weight per stool (BW) of sugarcane is a complex trait, which is the final product of a combination of many components. Diallel cross experiments were conducted during a period of two years for BW and its five component traits, including stalk diameter (SD), stalk length (SL), stalk number (SN), stalk weight (SW), and brix scale (BS) of sugarcane. Phenotypic data of all the six traits were analyzed by mixed linear model and their phenotype variances were portioned into additive (A),dominance (D), additive×environment interaction (AE) and dominance×environment interaction (DE) effects, and the correlations of A, D, AE and DE effects between BW and its components were estimated. Conditional analysis was employed to investigate the contribution of the components traits to the variances of A, D, AE and DE effects of BW. It was observed that the heritabilities of BW were significantly attributed to A, D and DE by 23.9%, 30.9% and 28.5%, respectively. The variance of A effect for BW was significantly affected by SL, SN and BS by 25.3%, 93.7% and 17.4%, respectively. The variances of D and DE effects for BW were also significantly influenced by all the five components by 5.1%～85.5%. These determinants might be helpful in sugarcane breeding and provide valuable information for multiple-trait improvement of BW. 相似文献

随着经济的发展和科学技术的进步,多媒体计算机正逐渐走进校园,走进课堂。作为一种先进的教学手段,多媒体的确具有其他媒体无法比拟的优越性。儿童的想象力最活泼、最丰富的,他们对直观、形象的画面尤其感兴趣。因此,教师的教学要根据儿童的心理特征发挥多媒体的动态感知的优势,为学生创设一个活泼、生动的获取知识、信息的氛围。让学生拥有广阔的思维空间,激励学生的想象,可以开拓学生的思路,增强学生思维的深刻性,有利于培养学生思维的灵活性。 相似文献

数字化转型的内在要求是实现人意识形态的数字化,用数字化的新视野栖身于全球数字化发展的浪潮中。我国高等教育数字化实践过程中,技术、范式和师生素养是影响学校发展的重要因素,同时也是数字化转型中面临的现实迷思。本研究通过分析梳理高等教育数字化转型过程中的实践逻辑,以数字文化空间与高等教育数字化转型相结合为出发点,界定高等教育数字文化空间的概念和特征,进而设计高等教育数字文化空间体系的框架结构,包括文化实践的物理空间、文化思辨的个人空间和文化创生的虚拟空间,同时,从打通数字通道、共享数字资源、创建数字环境和发展数字素养四个方面,提出高等教育数字文化空间的发展策略。 相似文献

对第16届广州亚运会游泳比赛中日男子自由泳运动员出发反应时（R.T）成绩进行对比分析与等级划分,结果显示：中国队在单人项目的短距离自由泳比赛中,R.T成绩总体对比逊于日本队,50m落后0.05s,相差较大,最好R.T成绩与日本队还有差距。4×100m接力比赛中无论个人还是全队,接棒R.T成绩发挥都优于日本队。中国队总体的R.T成绩还没有达到世界水平,还有很大的提升空间。 相似文献
