Tandem learning is a learning model actively used in the field of foreign language learning. Through interaction and mutual assistance between language partners, it is possible not only to learn independently and improve the level of target language, but also to conduct cross-cultural communication and understand foreign cultures.Generally speaking, there are two types of Tandem learning methods: Tandem learning through classroom management;The other is the out-of-class language partner learning activities organized by learners in both countries.This research is the second type of Tandem learning, in which teachers help to make connections between Chinese students in the accounting department and Korean students in the Chinese language department, and combine idioms to make mutual learning outside the normal classroom learning.Due to the lack of classroom management and constraints, as well as the low level of target language of both partners, some problems occurred in the process of activities.How to solve these problems so that the language partner activities can be carried out effectively, this study explored several solutions, and tested the effectiveness of the solutions through the end-of-term questionnaire survey.It is hoped that such a shallow study can serve as a starting point for more teachers and researchers to explore the out-of-class Tandem learning model so that more foreign language learners can benefit from Tandem learning.

It is important to investigate the hull response of a fishing vessel in waves to ensure the safety of it and to keep excellent sea-keeping qualities. For this purpose, we measured the response of fishing vessels in waves using real sea experimental measuring system. We analyze the experimental data by statistical method and spectral analysis to get the characteristics of the response of vessels which have different tonnage. In this real sea experiment, we use three stern trawlers which are the training ship in university. We know that the distribution of experimental response have Gauss distribution and Rayleigh distribution and smaller vessels have larger response.
