试论篮球教练员的临场指挥艺术

篮球比赛固然实力和经验重要,但两支球队实力相当时,教练员临场指挥起决定性作用。教练员临场指挥的任务是：保证全队遵守体育道德,在不利情况下果断采取应变措施及正确使用队员;事先制定的比赛方案与比赛情况不相符时及时修正,随时根据场上情况作出调度。     

热塑性长纤维增强复合材料模板施工实测分析

针对热塑性长纤维增强复合材料模板体系在剪力墙混凝土浇筑过程中的实测,探讨其简化计算模型的选取。现场实测结果表明:在混凝土侧压力和施工荷载的作用下,面板主要处于受拉状态,平面上两个方向的应变比为0.65～1.79, 说明该塑料模板的简化验算,除整体按双向板进行验算外, 尚应针对面板、水平肋、垂直肋等分别进行验算。

Rheology-based facial animation realistic face model

This paper presents a rheology-based approach to animate realistic face model. The dynamic and biorheological
characteristics of the force member (muscles) and stressed member (face) are considered. The stressed face can be modeled
as viscoelastic bodies with the Hooke bodies and Newton bodies connected in a composite series-parallel manner. Then, the
stress-strain relationship is derived, and the constitutive equations established. Using these constitutive equations, the face
model can be animated with the force generated by muscles. Experimental results show that this method can realistically
simulate the mechanical properties and motion characteristics of human face, and performance of this method is satisfactory.

刍议课堂应变的三个技巧

课堂教学是师生的双边活动,课堂教学的对象是活生生的人。几十名学生在一起学习,课堂教学中出现偶发事件、意外情况是难免的,也是必然的。当偶发事件出现时,作为教学掌舵人——教师,如何正确处理课堂教学中的偶发事件,保证课堂教学的顺利进行呢？笔者认为,应当因势利导,以变应变。     

金融危机情境下报业应变比较与思考

Macroscopic frost heave model based on segregation potential theory

A macroscopic frost heave model with more clear parameters was established. Based on a porosity rate frost heave model and segregation potential theory, a porosity rate function was deduced and introduced into the stress-strain relationship. Numerical simulation was conducted and verified by frost heave tests. Results show that the porosity rate within the frozen fringe is proportional to the square of temperature gradient and current porosity, and is also proportional to the exponential function of applied pressure. The relative errors between the calculated and measured results of frost depth and frost heave are within 3% and 15% respectively, demonstrating that the temperature gradient, applied pressure and current porosity are the main influencing factors, while temperature is just the constraint of frozen fringe. The improved model have meaningful and accessible parameters, which can be used in engineering with good accuracy.
