本研究将以海底捞为例。与实验方法相比，案例研究不限制研究的背景，也不干

This study will be fishing seabed example. Compared with experimental methods, case studies does not restrict research background, it does not interfere with the process of change phenomenon. In addition, a case or a case study to illustrate a plurality of selected questions and analyze the logical relationship between the event data collected (Carter et al, 2014). Therefore, the results of the case study method does not rely on sampling principles.

This study will take seabed fishing as an example. Compared with experimental methods, case studies do not limit the background of the study, nor interfere with the process of change of phenomena. In addition, case studies illustrate the problem through one or more selected cases and analyze the logical relationship between the event and the collected data (Carter et al, 2014). Therefore, the results of the case study approach do not depend on the sampling principle.

This study will take the bottom fishing as an example. Compared with the experimental method, case study does not limit the research background, nor interfere with the change process of the phenomenon. In addition, case studies illustrate problems through one or more selected cases, and analyze the logical relationship between events and collected data (Carter et al, 2014). Therefore, the results of case study method do not depend on sampling principle.
