非均匀推广的海森堡铁磁链模型与可积方程

利用延拓结构研究了可积的非均匀推广的海森堡铁磁链方程。通过将非均匀推广的海森堡铁磁链的自旋矢量取为闵可夫斯基空间中曲线的次法矢量，得到相应的耦合的非均匀可积方程。     

分布式科研项目评估管理系统的实现

讨论了一个分布式科研项目评估管理系统的实现.每个业务系统由多个节点构成,每个节点是一个科研项目评估管理系统.一个业务系统支持在多个地点以统一的标准进行科研评估业务.同一个业务系统中的各节点之间可以互相通信,交换评估标准和评估结果数据,不同的业务系统之间则互相保密.该系统遵循合理的评估方法,尽可能减弱主观因素对评估结果的影响.     

高温超导双晶结dc SQUID的I～V特性仿真研究

根据dcSQUID等效电路理论推导出描述dcSQUID特性的方程组,采用Matlab仿真工具软件对对称型高温超导双晶结dcSQUID进行仿真研究。仿真研究表明dcSQUID的输出电压是外磁通的周期性函数,其周期为一个磁通量子0。仿真研究的结果还为制备dcSQUID时,器件各参量的确定提供了有力的依据。     

对职技高师学报论文出版时滞的分析

对《河北职业技术师范学院学报》等5份学报的论文出版时滞、离散度进行了统计与分析。结果表明,5份职技高师学报平均刊发的论文出版时滞低于全国科技期刊的平均时滞、但离散度大,不适合当代科学技术发展的需要。提出了调整刊期、缩短稿件处理时间、通过创办网络版改革职技高师学报办刊模式等建议。     

脂肪酸胺铂的结构、理化特性及抗肿瘤效果

目的 为了开发新的铂类抗癌药物，对硬脂酸胺铂配合物结构、理化特性及抑制肿瘤作用进行研究。方法用红外光谱、元素分析对硬脂酸胺铂配合物的结构和理化特性进行研究。用MTT法对硬脂酸胺铂配合物体外培养的黑色素瘤(LiBr)、白血病细胞K562和肝癌(7721)细胞的杀伤效果进行研究。结果元素分析的实验结果与理论值相符。红外吸收光谱分析结果表明配合物中氨配体和硬脂酸配体分别以氨基的氮和硬脂酸的羟基氧与铂配位。结论硬脂酸胺铂配合物对肿瘤细胞生长活性抑制作用与胺配体及浓度密切相关。     

数学模型的一个应用

MGB probe assay for rapid detection of mtDNAl1778 mutation in the Chinese LHON patients by real-time PCR

Objective： Leber＇s hereditary optic neuropathy （LHON） is a maternally inherited degeneration of the optic nerve caused by point mutations of mitochondrial DNA （mtDNA）. Many unsolved questions regarding the penetrance and pathophysiological mechanism of LHON demand efficient and reliable mutation testing. This study aims to develop a minor groove binder （MGB） probe assay for rapid detection of mtDNA11778 mutation and heteroplasmy in Chinese LHON patients by real-time polymerase chain reaction （PCR）. Methods： Forty-eight patients suspected of having LHON and their maternal relatives underwent a molecular genetic evaluation, with 20 normal individuals as a control group at the same time. A real-time PCR involving two MGB probes was used to detect the mtDNA 1 1778 mutation and heteroplasmy. A linear standard curve was obtained by pUCmLHONG and pUCmLHONA clones. Results： All 48 LHON patients and their maternal relatives were positive for rntDNA11778 mutation in our assay, 27 heteroplasmic and 21 homoplasmic. Eighteen cases did not show an occurrence of the disease, while 9 developed the disease among the 27 heteroplasmic mutation cases. Eleven did not show an occurrence of the disease, while 10 cases developed the disease among 21 homoplasmic mutation cases. There was a significant difference in the incidence between the heteroplasmic and the homoplasmic mutation types. The time needed for running a real-time PCR assay was only 80 min. Conclusion： This real-time PCR assay is a rapid, reliable method for mtDNA mutation detection as well as heteroplasmy quantification. Detecting this ratio is very important for predicting phenotypic expression of unaffected carriers.     

An Empirical Study on Tangible Augmented Reality Learning Space for Design Skill Transfer

Tangible augmented reality (TAR) technology opens a novel realm which integrates the computer-generated elements into the real word. Its applications into design education have been explored with a limi-tation to this entire area. TAR offers an innovative learning space by merging digital learning materials into the format of media with tools or objects which are direct parts of the physical space. It is therefore conceived that such combination opens new perspectives in teaching and learning. This paper presented and evaluated one TAR system to improve the pedagogical effectiveness of experiential and collaborative learning process in urban design education. The results from the experiments were analyzed under a previously developed theoretical framework, which show that TAR can enhance the design activities in some collaborative work.
