树名刊意识 创特色名栏——兼谈《闽西职业技术学院学报》特色栏目的创建

高职院校学报近年虽取得飞速发展,但由于起步晚、底子薄、经验少,仍不能直面国内本科院校学报和国外学术期刊的竞争与挑战。高职院校学报要提升质量,就必须高屋建瓴,大胆树立名刊意识;挖掘特色,争创名栏;抓住契机,扩大学报影响力;同时还要构建高素质的学报团队,力葆特色栏目的青春,走特色强刊之路。     

浊度/分光光度法与毛细管等电点聚焦法测定明胶等电点及其分布的比较研究（英文）

等电点是蛋白质最重要的物理化学性质之一。目前有多种测定等电点的方法。本文利用最简单的浊度/分光光度法和最先进的毛细管等电点聚焦法分别测定了河南牛皮明胶的等电点，对两种方法进行比较并论证了后一种方法的优势。     

Serum proteins analysis by capillary electrophoresis

The purpose of this study was to evaluate the efficacy of multi-capillary electrophoresis instrument in clinical laboratory. An automated clinical capillary electrophoresis system was evaluated for performing serum proteins electrophoresis and immuno-fixation electrophoresis by subtraction. In this study the performance of capillary electrophoresis was compared with the cellulose acetate membrane electrophoresis and agarose gel immunofixation electrophoresis for serum proteins. The results of capillary electrophoresis and cellulose acetate membrane electrophoresis were good (r=0.89∼0.97) for protein fractions and A/G ratio except for β-gobulin fraction (r=0.60). Both within-run and day to day precisions (CVs) of assay results for 5 main fractions and A/G ratio (n=10) were between 0.3∼6.3%. The reference ranges of serum protein fractions obtained from 200 healthy individuals by cellulose acetate membrane electrophoresis were almost equal to that of capillary electrophoresis except for α-1 globulin fraction. No significant difference of electropherograms between cellulose acetate electrophoresis and capillary electrophoresis was observed in the abnormal serum such as presence of bilirubin (<20mg/dl), hemoglobin (<300 mg/dl), lipid (Intralipos <1%) and samples from patients with acute phase response, liver injury, polyclonal hyper gammaglobulinemia or M-proteinemia. The method of capillary immuno-fixation electrophoresis by subtraction showed good agreement with agarose gel immunofixation electrophoresis by subtraction identifying 30 monoclonal gammmopathy patient samples.     

加连杆的冷弯薄壁卷边槽钢受压性能试验研究与有限元分析

畸变屈曲作为控制冷弯薄壁卷边槽钢柱承载力的重要模式之一，正逐步受到国内外研究人员的重视。本文针对畸变屈曲的变形特征，通过12根试件在不同连杆布置方式下的轴心受压和偏心受压试验研究，验证在冷弯薄壁卷边槽钢的卷边处设置连杆用以提高其承载力这一方法的有效性．得出了最有效的连杆布置方式。同时，采用有限元软件ABAQUS对试件进行了模拟分析，探讨了初始缺陷、双向偏心等因素的影响。     

以滑移机理探讨色谱分析的塔板数

以滑移色谱机理弥补塔板理论的不足，滑移色谱机理的色谱流出曲线函数可更真实地表达实际色谱流出曲线。在计算色谱柱塔板数时，应区分色谱柱塔板数和色谱峰塔板数（是由实际色谱峰形得到的，在色谱过程中实际发生的），因色谱柱塔板数与色谱峰塔板数是不同的概念。推导出色谱拄塔板数与色谱峰塔板数之间的关系式。该关系式成功地解释了通常色谱峰显著拖尾的原因。丙酮在GDX-101上的吸附焓△H=-3.6k．J／mol.     

用ODO冷冻断裂法观察人膈腹膜间皮细胞和毛细血管的超微结构

ONO冷冻断裂法是一项新的扫描电镜制样技术。利用这项技术,将样品在-196℃下冷冻,然后把样品掰裂。用扫描电镜观察样品断裂面细胞的内部结构,具有较高的分辨率。并能显示细胞内部细胞器之间的关系。其缺陷是欲观察的断裂面不能预先确定,而是随机的。作者应用ODO冷冻断裂法,对人膈腹膜间皮细胞和毛细血管进行了观察.     

基于引文分析法的期刊栏目的学术影响力评价

以中国引文数据库为基础,以《中州学刊》为例,对该刊5年间各栏目发表论文的情况和论文被引用的情况进行了统计与分析。结果表明,用论文被引率作为各栏目学术影响力的评价指标,可以定量而客观地评价社科学术期刊各栏目的学术影响力,社科学术期刊栏目的学术影响力的大小与各栏目发文量的大小不存在一一对应关系。

Numerical Modelling of Performance of R22 and R290 in Adiabatic Capillary Tubes Considering Metastable Two-Phase Region--Theoretical Model Description and Validation

A homogeneous theoretical model is developed to predict the performance of R22 and R290 in adiabatic capillary tubes. The model is based on conservation equations of mass, momentum and energy. Metastable both liquid and two-phase flow regions are considered in the model. In metastable two-phase region, superheated liquid is introduced into the metastable mixture viscosity and two methods are presented to evaluate it. The model is validated by comparing the predicted pressure and temperature profile and mass flow rate with several investigators′ experimental data of R22 and one of its alternatives R290 reported in literature. All of the predicted mass flow rates are within ±8% of measured values. Comparisons are also made between the present model and other investigators′ models or sizing correlation. The model can be used for design or simulation calculation of adiabatic capillary tubes.
