Multicultural experience refers to those experiences gained through individuals' contact with other cultures. This study focused on exploring whether knowledge of different cultures can improve creative performance-and also how multicultural experiences influenced this performance through changes in individual's physiological mechanisms. Study 1 explored the influence of different cultural priming on creative story-writing tasks. Eighty-nine Chinese college students were randomly assigned to 4 conditions: sole American culture, dual cultures, sole Chinese culture or control condition, and made to watch 45 min slides with cultural elements—including pictures, music and videos,—and then they were asked to complete the creative story-writing task. The results showed that American culture priming group's score was significantly higher than the control condition with regards to the uniqueness and novelty of the creative story-writing task. Study 2 was aimed at exploring the relationship between physiological arousal levels induced by different cultural and creative performance. We divided the whole experiment into five stages,—including the baseline, picture, listening to music, watching video, and completing creative tasks. Through Biofeedback measurement, we recorded the physiological indexes of participants in different groups in every stage, including skin conductance, thermal, electroencephalographic, and heart rate. The results showed that contacting with foreign cultures would increase individuals' physiological arousal level and brain activity, which contributed to the following creative task.

The coal-bearing strata of Longdong mine field in Xingtai is the Carboniferous-Permian. The No.8 coal seam is located in the Taiyuan formation and is the main minable coal-bed. The coal is mainly gas-fat coal accompanied with coking coal, lean coal and anthracite. The results of the macroanalysis and maceral quantitative analysis on the main minable coal-bed show that the degree of coal metamorphism takes the old town as the center and is distributed concentrically outward and the anthracite and lean coal are distributed nearby the old town, and the coal gradually becomes coking coal, gas-fat coal and gas coal further outwards. The degree of coal metamorphism was affected by regional metamorphism, and the coal seams which are close to the old town stack the regional magmatic thermal metamorphism. The conclusions of the research offer a scientific foundation to exploit the coal resource in this area?

Eriksson once said: Adolescence is a critical period of identity construction, but there is a group of student video producers who project their desire for identity into the identity of the video producer, which is BiliBili's student video maker. This article takes this group as the research object and then analyses and sorts out their individual identities, video content, and their needs of the times to study the relationship between their expression of opinions in the works and identity construction, and how they integrate students with the identity of the video maker is balanced, etc.
