It gets the conclusion as follows : 1 . to different degree of physics knowledge , there is significant difference in integrate , hypothesis , variable control and experiment design 研究二得出如下结论: ( 1 )不同物理基础的学生在实际应用、知识整合、猜想假设、变量控制和实验设计上表现出显著差异。
Currently a consensus has been reached in the neurology circle that spinal cord injuries are repairable , but the past studies had shortcomings such as defective experiment designing and unsatisfactory repeatability 目前神经科学界已经达成广泛共识:脊髓损伤最终是可以修复的,但既往研究尚存在实验设计上的缺陷、实验结果不能很好的重复等问题。
The design method of heavy metal interaction experiments basing on half growth inhibition concentration ( ic50 ) and common safety concentration , a new method of heavy metal interaction experiment design method was proposed 重金属交互作用试验设计的方法运用半抑制浓度和公共最大非抑制浓度两个参数,提出了一种重金属交互作用试验设计的方法。
In order to solve this problem this paper simplified the engineering problem and finish two experiments design such as pipe deformation measurement experiment and fog search north experiment that obtain a well experiment effect 针对这一问题本文最后对工程问题进行了抽象,完成了管道形变测量实验和光纤陀螺寻北实验的设计,取得了很好的实验效果。
This paper carry out experimental study of the heat transfer and flow resistance characteristics of high prandtl number fluid in 3 - d internally crossing - finned tubes with cross - experiment design method . use oil as work media 本文以未使用过的润滑油为工质,用正交试验设计方法,对高pr数流体在肋叉排列三维内肋管中的传热和流阻特性进行了实验研究。
