Artificial intelligence (AI) era challenges the use and functions of emotion in college students and the students’ college life is often experienced as an emotional rollercoaster, negative and positive emotion can affect the emotional outcomes, but we know very little about how students can ride it most effectively to increase their creativity. We introduce frustration tolerance as a mediator and emotion regulation as a moderator to investigate the mechanism of creativity improvement under negative emotion. Drawing on a sample of 283 students from professional music colleges or music major in normal universities, we find that negative emotion are generally associated with a lower creativity, while frustration tolerance can mediate the relationship between negative emotion and creativity, but these effects depend on the emotion regulation. Cognitive reappraisal exerts a negative effect on the relationship between negative emotion and creativity, while expressive suppression has the opposite effect. Our study contributes to the literatures on student’s emotions and creativity in music education and to the emotion regulation literature.

附面层边缘通常取在速度达到主流速度0.99倍的位置,而复杂流场中主流流动往往并不均匀,给附面层边缘的准确识别造成了困难.为解决此问题,提出了用“参考主流”代替实际主流识别附面层边缘的方法:通过零剪切力滑移壁面边界条件下数值模拟得到不受附面层干扰的参考主流,在根据附面层定义确定附面层边缘时以该参考主流中的速度代替实际的主流速度.通过斜楔压缩和弯曲压缩两个超声速压缩流场对该识别方法进行了验证,所得到的斜楔压缩出口截面上附面层厚度与采用实际主流速度判断得到的厚度相对误差仅4.1％.根据该方法的识别结果对弯曲压缩型面设计进行附面层修正后,弯曲激波高度与无黏设计值之间的误差从修正前的2.0％降低至0.3％,压缩面末端压力的相对误差从修正前的6.6％降低至2.3％.该方法避免了指定主流速度的主观性,识别结果较为准确.

面临新型冠状病毒肺炎这类新发传染病暴发,在防疫物资供应吃紧情况下,国家多次下发关于医用防护服使用通知:“医用防护服供给不足时,可使用在境外上市符合日标、美标、欧标等标准的医用防护服”[1-3].由于各国标准对防护服的性能评价的侧重点不同,使得同一件产品的质量在不同标准的要求下显得参差不齐.医用防护服是抗击新型冠状病毒肺炎疫情的重要保障物资之一.由于本次疫情涉及范围广,感染人数多,对防护服需求激增.符合我国标准的防护服已不能满足需求,大量境外防护服作为应急物资进入医疗机构.然而不同国家医用防护标准不同导致医疗机构使用困惑.为此,本文对国内外医用防护服标准进行比较和分析,为合理选择医用防护服提供参考依据.

With the rapid development of economy, city residents' income has a significant improvement. At the same time, more attention will be focused on healthy life and physical exercise. In view of this, the relationship between economic level and sports consumption was studied in this paper. Firstly, the analytic hierarchy process (AHP) was adopted, and the relationship model between economic level and sports consumption was constructed. Then, the relationship between the economic level and the sports consumption was studied through the stratified score and the relevant probability theory. Finally, the empirical analysis of the sports consumption structure was carried out in Xi'an. The results show that the development of economic level has led to sports consumption. The higher the economic level, the greater the intensity of sports consumption will be.

Automobile Application is a skill-applied engineering major group in vocational colleges, which fo-cuses on the operation and application of post skills. It differs greatly from majors of Arts and Science in the teaching process. This paper analyzes the reasons why the teaching reform should be carried out in the cur-riculum setup and practice base construction, and then summarizes the experience gained from teaching re-form that it is advisable that curriculum is to be set based on the structure principle and practice base is to be constructed based on the various teaching modules.

The working process based on curriculum development is the direction of curriculum reform of occupation education software technology professional. The relevance of the occupation education curriculum based on working process is not strong that caused the courses loosing.
