Methods: from March to July 2021, 800 students who studied the comprehensive experimental courses of histology and embryology were randomly divided into the control group (conventional teaching mode) and the observation group (mixed teaching mode). The statistical differences in the five dimensions of comprehensive quality (learning interest, autonomy, professional belief, thinking ability and humanistic quality) of the two groups of students before and after teaching were compared, and the statistical differences in the satisfaction degree of the two groups of students and teachers with the teaching process were compared. Results: the scores of the five dimensions of comprehensive quality (interest in learning, humanistic quality, professional belief, thinking ability and autonomous learning) of the students in the two groups were increased. the scores of comprehensive quality of the students in the observation group were higher than those in the control group after teaching, and the difference was statistically significant (P<0.05). The satisfaction rate of the observation group (86.00%) was higher than that of the control group (71.50%), the difference was statistically significant (P<0.05). Conclusion: the application of mixed teaching model in the comprehensive experimental teaching of histology and embryology can comprehensively improve students comprehensive quality and improve students satisfaction with the teaching process.展开更多

In the process of fault detection and diagnosis, students' basic engineering practical ability, professional design ability and innovative thinking are fully improved and developed according to the project design plan. Practice has proved that the establishment of a complete experimental vehicle detection and fault diagnosis course provides a new and effective way for the training of professional talents in the automotive field.展开更多

To explore the feasibility of this experiment teaching system and mode, we developed PCS as an elective course. The PCS is designed with two sections: pharmaceutical comprehensive design(PCD) and pharmaceutical comprehensive experiment(PCE). The PCD section includes literature review, comprehensive project design and oral examination. PCE can be divided into four parts: synthesis, quantitative determination, pharmacodynamic evaluation, and formulation and quality determination. Course grade was determined by experimental performance, written report, literature review, new project design and oral examination. The learning interest, experimental ability, theoretical level and literature retrieval ability, team spirit and interpersonal skills have been all significantly improved among students taking this course. A survey was administered at the end of the semester to the enrolled students. The responses were reported as percentages, and the feedback was positive. The course was highly recommended by the teaching inspection committee. This new course plays an important role in developing students’ creativity and comprehensive ability. It could help students understand the focus and features of every secondary discipline, as well as establish scientific and reasonable knowledge system. Most students can better understand the process of drug research after this course.展开更多

The results presented in this paper also demonstrate that the ratios of d,z_0 to crop height h usually vary with canopy ar- chitecture,atmospheric stratification and turbulent exchange intensity,and are not just constants as commonly assumed or used.d/h raises with an increase of relative height of the maximum foliage layer and wind extinction coefficient within the canopy.Only for crops with short stem and moderate foliage density,can the relations d= 0.64h,z_0=0.08h keep stable.In addition,for long stem crops or sparse canopies,the fairly large shear stress at the soil surface and the va- riation of the exponent in the relationship between drag coefficient and wind speed undoubtedly influence the accuracy of CPM to a certain extent.展开更多
