查询词典 experimental research

In summary, various key experimental conditions in electron acoustic imaging of ferroelectric domains were systematically studied. The optimum experimental conditions to obtain EAI of domains with good quality and the factors important to image analysis have been presented. The piezoelectric vibrator model and calculation of motion equation are helpful for explaining the imaging mechanism and related experimental phenomena. The sample holder with variable electric field was designed. The domain movement of BaTiO〓 ceramics and crystal under lateral and longitudinal applied electric field and domain movement of PMN-PT crystal under longitudinal poling electric field were observed. The application of SEAM on revealing of ferroelastic domains, imaging of residual stress distribution in ceramics coatings and around the pores on the surface of ferroelectric ceramic composite have been reported respectively. All these works enriched the study of electron acoustic imaging and extended the application of SEAM in the characterization of materials.

Independent-samples t-test is used to compare means of the experimental and control groups.The statistical results reveal that collocational competence with the sub-technical terms of the experimental group is significantly higher than that of the control group. However, the CBSTT model's effect on the simple nominal phrase collocational competence is more significant than the effect on the complex nominal phrase collocational competence. From the perspective of production competence, the overall results of the experimental groups are significantly higher than the overall results of the control group. The complex nominal phrase production competence is not significantly developed at the beginning of the experiment. With the progress of the experiment, the differences from the two groups become salient.

在短语搭配能力方面，实验组学生的总成绩明显高于对照组学生，其中实验组简单短语的搭配组合能力与对照组学生存在显著差异，但复杂短语的组合能力上两组差异不大；在产出能力方面，实验组学生的总成绩也明显高于对照组学生，实验组简单短语的产出能力与对照组学生存在显著差异，复杂短语的产出能力开始没有显著差异，随着实验的进行差异越来越显著；在通过词汇重复手段以构成语篇衔接方面，实验组学生的成绩和对照组的学生无显著差异。
