Theoretical and experimental studies of heat transfer with moving phase-change interface in freezing and thawing of porous potting soil     

Michael K. H. Leung  Kit-ying Chan 《浙江大学学报(A卷英文版)》2009,10(1):1-6

Soil in a cold region is subject to frequent freezing and thawing cycles. Soil frozen for a prolonged period may cause adverse freeze damage to the plants due to cell dehydration or root cell rupture. It is important to understand the detailed heat transfer behaviors of the freezing and thawing processes to prevent freeze damage, and to devise proper mitigation measures for effective pot planting in cold regions. A theoretical model was developed to analyze the transient moving phase-change interface heat transfer in the freezing and thawing of porous potting soil. The theoretical derivation is based on the assumption that the soil freezes completely at a single temperature. Microscopic poromechanic effects on heat transfer behavior were ignored. The spatial domain of the problem was simplified to a 1 D spherical coordinate system with variation in the radial direction. Green＇s function was applied to solve for the time-dependent body temperature. Experiments were conducted for validation of the theoretical model Reasonable agreement between the theoretical predictions and experimental measurements was obtained. The theoretical model developed can be easily used to determine the sensitivity of various parameters in the freezing/thawing processes, e.g., thermal properties of soil, ambient temperature, and planting pot size.  相似文献   

BGP路由摆动抑制机制与路径探索     

周婵 《贵州教育学院学报》2005,16(4):89-91

路由摆动抑制是普遍用于网络路由协议的一种机制。其目的在于通过暂时抑制那些短期内发生快速变化的路由，而限制不稳定路由的全局影响。普遍认为这一抑制机制有助于Internet全局路由的稳定性，但研究表明BGP的路径探索可能错误地引发抑制，甚至仅仅一次路由摆动都可能导致路由收敛时间的大大增加。  相似文献   

Chinese number‐naming advantages? Analyses of Chinese pre‐schoolers' computational strategies and errors     

Cheng Zijuan  Lorna Kim Sang Chan 《International Journal of Early Years Education》2005,13(2):179-192

Simplicity in number naming in a language (e.g. ‘ten‐two’ in Chinese is simpler than the irregular ‘twelve’ in English) has been used to explain cross‐cultural disparities in children's computational competence. In contrast to previous research focusing only on whether children can provide the correct answers, in this study (N?=?117 and 92) we examined Chinese pre‐schoolers' computational strategies in depth and individually so as to examine their understanding of the base‐10 system and place value. The results showed that despite the fact that many can give the correct answers, there is strong evidence that Chinese pre‐schoolers do not have adequate understanding of the base‐10 number system and place value, suggesting that the advantages of the simpler number‐naming system are limited.  相似文献   

Belonging to a workplace: first-year apprentices’ perspectives on factors determining engagement and continuation through apprenticeship     

Selena Chan 《International Journal for Educational and Vocational Guidance》2016,16(1):9-27

The transition to work through apprenticeship is one taken by many young people. A sense of belonging to a workplace is posited to be an important precursor for initial and on-going engagement with practice communities. This article details a study of beginning apprentices in ten trades. The project sought to identify factors influencing apprentices’ decisions to enter and commit to apprenticeship. Through comparisons of the experiences of continuing and disengaged first-year apprentices, processes of belonging to a workplace were found to be important contributors to apprenticeship continuation. Factors contributing to apprentices’ perceptions of belongingness are identified, examined and discussed.  相似文献   

真德秀评点中的公文本体论与文体论   总被引：1，自引：0，他引：1  

王婵 《河南师范大学学报(哲学社会科学版)》2006,33(6):173-175

真德秀《文章正宗》所收文章中公文所占的分量极大,而且在其评点中还隐含了大量的公文思想。它首先论述到了公文本体方面的各种问题。还论述了公文中主要文种的概念,并先后对“对”、“谏”、“论”等文体进行过全方位的考察,使后学者真正了解这些实用公文文体的特性。由真氏对“议论”这类公文文体的评语,可见其在公文文体理论史上的地位。真氏评点中的公文理论值得我们深入探讨。  相似文献   

Self-concept among hearing Chinese children of deaf parents     

L M Chan  B Lui 《American annals of the deaf》1990,135(4):299-305

This paper discusses a study of Chinese children in Hong Kong that compared the self-concepts of hearing children of deaf parents with the self-concepts of hearing children of hearing parents. The study was based on the responses to a questionnaire given to 42 deaf couples and their 70 hearing children, and 41 hearing couples and their 82 hearing children. It found no differences in the self-concepts of hearing children of deaf parents and hearing children of hearing parents. However, it did find that deaf parents had lower self-concepts than hearing parents.  相似文献   

Evaluation of small‐group teaching in human gross anatomy in a Caribbean medical school     

Lap Ki Chan  Pallab K. Ganguly 《Anatomical sciences education》2008,1(1):19-22

Although there are a number of medical schools in the Caribbean islands, very few reports have come out so far in the literature regarding the efficacy of small‐group teaching in them. The introduction of small‐group teaching in the gross anatomy laboratory one and a half years ago at St. Matthew's University (SMU) on Grand Cayman appears to have had a significant positive impact on the academic achievement of students in anatomy. This study surveyed the responses of the students to the small‐group learning method in gross anatomy at SMU using a structured questionnaire. The results show that our students prefer this small‐group learning method over a completely self‐directed method in the gross anatomy lab because the study materials were carefully chosen and the study objectives were demonstrated by the resource person. However, teacher‐centered teaching was deliberately avoided by fostering problem‐solving skills in the anatomy lab sessions. Another aim of the small‐group teaching at SMU was to develop the interpersonal and communication skills of the students, which are important in their later education and career.

Voices of donors: Case reports of body donation in Hong Kong     

Chiu HY  Ng KS  Ma SK  Chan CH  Ng SW  Tipoe GL  Chan LK 《Anatomical sciences education》2012,5(5):295-300

Body donation is important for medical education and academic research. However, it is relatively rare in Hong Kong when compared with many Western countries. Comprehensive research has been performed on the motivation for body donation in Western countries; however, there is still insufficient research on body donation in Hong Kong to provide information on how to increase the body‐donation rate. To understand the factors involved in the decision to donate one's body, the authors interviewed a registered donor and the daughter of another donor in Hong Kong. The authors interpreted the information collected in light of the available published reports, which mostly focus on body donation in Western countries. Despite the consistency of some demographic factors and motivations between the participants in our study and those investigated in the published reports from Western countries, there are differences in education level and socioeconomic status between the donors in our study and those from Western studies. The authors also suggest that Confucianism and Buddhism in Chinese culture may motivate potential body donors in Hong Kong. Other important factors that influence the body‐donation decision may include family members' body donation, registration as organ donors, and good doctor–patient relationships. Although case report studies have their limitations, this study allows us to explore the complexity of events and establish the interconnectivity of factors involved in body donation, which could not be achieved in previous survey‐based studies. © 2012 American Association of Anatomists.  相似文献
