最大熵法新倒频谱分析——倒熵谱研究
怀
力学学报 , 1985, DOI: 10.6052/0459-1879-1985-5-1985-062
Abstract: 本文提出用最大熵法和最大熵法与富氏谱法相结合的综合变换方法求倒频谱——“倒熵谱”的新方法。给出了倒熵富谱法(cEFM)、倒富熵谱法(cFEM)和倒熵熵谱法(cEEM)等几种新倒谱算法,解决了以往倒谱分析中频率分辨率难以提高的困难,减小了窗函数产生的影响,使倒谱旁辦大大减轻,文內给出了实际计算结果,并与常规倒谱(本文称之为倒富富谱cFFS)进行了对比。
减速机箱体动态激励力的试验研究
李惠彬,怀,郑兆昌
力学与实践 , 1999, DOI: 10.6052/1000-0992-1999-046
Abstract: 采用在轴承外圈上安装套圈并粘贴应变片的方法对二级齿轮减速机箱体所受的动态激励力进行了测试和分析,并在此基础上得出了有关影响减速机箱体动态激励力的主要因素的有益结论。对减速机动态设计和减速机故障诊断有着积极的意义。
2D教学与裸眼3D教学比较——在香港小学使用裸眼3D进行教学的案例研究

Abstract:

虽然之前的研究结果显示3D教育的前景十分广阔,但是观看3D内容的标准方式在香港实行起来并不实际,原因是现在许多学生患近视眼,日常生活中就需要佩戴眼镜,如果这些学生观看非裸眼3D影片则需要同时叠戴两幅眼镜。为了探索3D教育应用在小学课堂上的教学效果,香港三所大学和IAAI(工业和学术应用学会)联合做了一个在香港小学使用自动多视点LCD显示屏进行通识课程教学的案例研究。本文将对这个案例研究进行阐述。我们的研究结果表明:小学生在学习以科学为主题的课程时,3D教学比2D教学能够达到更好的学习效果,该研究结果具有重要意义。

Although previous research has shown promising results on 3D in education, the standard method of viewing 3d content would not be practical in Hong Kongas many students need to wear two pairs of glasses due to nearsightedness. In order to explore the result of using 3D technology in primary school edu- cation, three universities in Hong Kong collaborate with IAAI to present a study of using the automultiscopic LCD display for 3D teaching on General Studies in a primary school in Hong Kong. Significant findings support that pupils learn science topics in better in 3D than in 2D.

 

改革开放与大学管理教育兴起
Reform and Opening??Up and the Rise of University Management Education

- , 2018, DOI: 10.15896/j.xjtuskxb.201806001
Abstract: 结合重要事件的回顾,分酝酿恢复期、渐进发展期和快速发展期三个阶段阐述中国大学管理教育在20世纪末20年的兴起历程。“文革”结束不久,长期贴上资产阶级标签的管理学,被认同是一门科学。随后,摆脱姓“社”姓“资”和计划经济与市场经济的争论,大胆提出向资本主义国家学习先进管理,并在管理教育领域和国外合作。正是破除了这些思想禁锢,坚持改革开放,管理教育才能从空白兴起,成为大学主流学科。可以说没有改革开放就没有今天的大学管理教育。
By reviewing important events, this paper explains the two decades′ development of university management education in China in the late 20th century, which is divided into three stages: The recovery period started shortly after the end of the Cultural Revolution, management, long labeled as bourgeois, was recognized as a science. Later, followed the asymptotic development period, when the point of view whether capitalism or socialism should be held , or planned economy and market economy should be carried out was no longer debated, instead, to learn advanced management from capitalist countries and cooperate with foreign countries in management of education was boldly proposed. It is precisely by breaking down these ideological constraints and adhering to reform and opening??up that management education could emerge and has become the mainstream subject of universities, which comes the rapid development period. Therefore, there would be no university management education without reform and opening??up

MULTIPLIERS OF THE DIRECT SUM OF BANACH ALGEBRAS AND THE SPECTRAL THEORY
Banach代数直和上的乘子及其谱理论

JIANG Qiaofen,ZHONG Huaijie,
,怀

系统科学与数学 , 2010,
Abstract: The representation of multipliers of the direct sum $\mathcal{A}\oplus\mathcal{A}$ of Banach algebras $\mathcal{A}$ is considered. By means of the representation, a series of results about the spectral theory of multipliers of $\mathcal{A}\oplus\mathcal{A}$ is given. At last, a result about strongly irreducible operators is obtained.

热带气象学报 , 1988,
Abstract: 本文对新丰江流域初夏暧云的含水量与小云滴谱特征进行了分析。指出暖积云的含水量比暖性层积云大;广东初夏暧性层积云的含水量大于北方降水性as—ns云系。被探测云的主要降水机制均为碰并增长过程,但浓积云中云滴碰并增长条件比层积云优越;与湖南等地积云相比,广东积云更具有海洋性积云的特征。
