The direct stress distrilouted on the cross-section of flexed "I" girder has been determined with electrometic method in this paper.

本试验主要通过电测法测定：工字梁在弯曲时横截面上的正应力分布，并与理论值比较，以验证弯曲正应力公式，并且对材料合理选用进行分析。

The creative-thinking strategies such as SCAMPER、brainstorming、attribute listing and synectics were used to guide members in the experimental group to conceive the idea of vector drawing.

研究设计采不等组前后测准实验设计，实验组和控制组皆先进行相同的向量绘图技能教学，待两组学生在「专业」成分具相同基本技能后，实验组施以「创思向量绘图教学」，在引导构思时，导入SCAMPER、脑力激荡、属性列举法及分合法等创造思考策略，控制组则以范例作品欣赏及全班问与答的方式进行引导。

According to the test results, the soil-water characteristic curves between degree of saturation and suction shift to the right with decreasing void ratio, and the drgree of saturation and void ratio present the good linear relation with almost the same gradient under different constant suctions.

采用滤纸法测得Kunigel V1钠基膨润土的土水特征曲线，试验结果表明随着孔隙比的减小，饱和度与吸力间的关系曲线右移；吸力一定时，饱和度与孔隙比间呈线性关系，而且其斜率在不同吸力时相近。
