大学生思政课学习动力不足主要表现在缺乏学习热情、学习逃避行为、存在消极心态、缺乏明确目标等方面,其成因与思政课教学内容缺乏足够的吸引力、教师教学方式单一等有关,也与大学生在高中阶段对大学生活的“非理性”想象和对专业学习缺乏全面认识有关。在学习动机理论的视野下,教师可以从以下途径入手提升大学生思政课学习的动力,即建立良好的师生关系、建构学生思政学习“动力程”、促进师生课上良性互动和引导学生自觉进行知识信息整合。

Cyclic AMP-binding protein was purified 30 fold from the mycelia of Ganoderma lucidum by the methods of ammonium sulfate precipitation, DEAE-cellulose, phospho-cellulose ion exchange chromatography and Sephacryl S-100 gel filtration. The molecular mass of the purified protein is 34.5 kDa and 17 kDa by Sephacryl S-100 gel filtration and SDS-ployacrylamide gel electrophoresis, respectively. From these results it is suggested that the protein has a homometric dimmer structure. The pI of the purified protein is pH 8.2 by native isoelectric focusing gel. The half-life of the protein activity in 10% glycerol at 4 ℃ is 7 d in crude extract, but its half-life is only 3 d under purifying conditions. The optimal conditions of the protein activity are at 1 ℃ and pH 7.5. Its activity is increased 6 times by 1 mmol/L Zn^(2+) and is slightly inhibited by cGMP, Cu^(2+) and Mn^(2+).

Based on the computerized symbolic Maple, we study two important nonlinear evolution equations, i.e., the Hirota equation and the (1+1)-dimensional dispersive long wave equation by use of a direct and unified algebraic method named the general projective Riccati equation method to find more exact solutions to nonlinear differential equations. The method is more powerful than most of the existing tanh method. New and more general form solutions are obtained. The properties of the new formal solitary wave solutions are shown by some figures.
