一种基于.NET和VBA互操作模型的Web报表实现方法

针对在B/S结构下生成Web报表比较复杂的情况,讨论了三种常用的Web报表生成方案:直接利用Win32API编程接口设计报表、采用水晶报表编辑器设计报表和使用第三方控件生成报表。在分析了上述三种方案的优缺点基础上,文章提出了一种比较实用的基于.Net和VBA(Visual Basic for Applications)互操作模型的Web报表设计方法。实际应用效果表明:采用该模型进行Web设计具有易用性强、灵活性高等优点,同时能够节约软件开发成本10%左右。并且验证了该模型的有效性和可靠性。

A study of teacher cognition in planning elementary science lessons

Advances in cognitive psychology and in research techniques have led to an increase in the acceptance of the conception of teaching as a “thoughtful” profession. The interest and enthusiasm of researches in aspects of teacher cognition demonstrate a shift from an emphasis on observable teacher behaviours to a focus on a teacher's unobservable thinking process. In this study, a qualitative approach was used to uncover a teacher's thinking process during lesson planning, to depict a more holistic view of the structural complexity of teacher cognition during lesson planning. Specialised science teachers and general teachers who had different levels of subject expertise were studied. The teachers were interviewed on how they planned an elementary science lesson. Interview protocols were analysed using a taxonomy which assessed the cognitive complexity of teacher thinking. Differences were found between specialised science teachers and general teachers in the levels of structural complexity in their thinking process.     

Study of Cellular Experiment of Electric Pulse Imposed on Cancer Cell

The objective of the study is the cytocidal and inhibitory effect of energy-controllable pulse on ovarian cancer cell line SKOV3.Ovarian cancer cell suspension were treated by electric pulse with different parameters,.The inhibitory rate(IR) was assayed by modified colorimetric MTT methods,the growth curves of two test groups and one control group were also measured.and the ultrasturctureal changes were observed under electron microscopy(EM) and scan electron microscopy (SEM),It was found that the treated SKOV3 cell proliferated more slowly.IR was increased with the enhancement of pulse paramters,The ultrastructural study showed that morphological changes occured obviously.Swollen mitochondria,fracutured ridges,cytoplasmic vacuoles and membrane holes appeard in most of the processed cells,and a part of bilayer membrane was ruptured.It is indicated that irreversible electric breakdown occurred in some of the treated cells,and the electric pulse could kill cancer cell and inhibit its recovery and growth.
