研究表明：要想成绩好 按时吃早餐（双语）
Chinese researchers have analyzed big data to find that university studentswith better academic performance are more likely to eat breakfast in the
cafeteria, especially on cold days, according to their findings published in a
British journal.
中国研究人员在英国期刊上发表的一份研究结果表明，他们通过分析大量数据发现，学习成绩好的大学生更有可能按时在食堂吃早餐，尤其是在寒冷的季节。
Writing in the Journal of the Royal Society Interface, they concluded there
is a significant positive correlation between college students’ academic
performance and the regularity of campus daily life, in which having meals and
taking a shower on time are two measuring factors.
他们在《英国皇家学会杂志》上发表文章称，大学生的学习成绩与校园日常生活的规律性之间存在显著的正相关关系，其中按时吃饭和洗澡是两个重要的衡量因素。
In contrast to Western countries, teachers and administrators in most Asian
countries often ask students to be self-disciplined both in and out of class.
"Do routines in life help a student get a better academic performance? We hope
to answer this question," said Zhou Tao, one of the researchers.
与西方国家不同的是，大多数亚洲国家的老师和管理者经常要求学生在课堂内外都要自律。参与这项研究的人员周涛表示，“日常生活是否有助于学生取得更好的学习成绩?我们希望能回答这个问题。”
Researchers from the University of Electronic Science and Technology of
China (UESTC) in Chengdu, Southwest China’s Sichuan province, collected about 30
million digital behavioral records of 18,960 UESTC undergraduate students in
three years from 2012 to 2015.
中国西南部四川省成都市电子科技大学(UESTC)的研究人员在2012年至2015年的三年时间里，收集了约3000万份学生电子行为记录，涉及18960名本科生。
The behavioral records were on their campus smart cards, covering when they
entered the library, took a shower, washed clothes, paid for meals in the
cafeteria and other components of daily routines, The Beijing News reported on
Monday.
据《新京报》周一报道，这些行为记录在他们的一卡通上，包括他们进入图书馆、洗澡、洗衣服、在自助餐厅吃饭以及日常生活等内容。
In most Chinese universities, every student owns a campus smart card with
real-name registration, which can be used for student identification and serves
as a payment medium on campus.
在中国的大多数大学里，每个学生都拥有一张实名制的校园智能卡，可以用来识别学生身份，并作为校园内的支付媒介。
We applied the well-known Spearman rank correlation coefficient to quantify
the correlation strength. The coefficient lies in the range of negative one to
positive one and the larger the absolute value is, the higher the correlation
is, said Cao Yi, who also participated the study.
参与研究的人员曹毅说：“我们用著名的斯皮尔曼等级相关系数来量化相关强度。该系数在负1到正1之间，绝对值越大，相关性越高。”
The correlation coefficient for GPA and having a meal regularly is 0.128
and that for taking shower regularly is 0.157, Cao said. Both suggest a strong
positive correlation between academic performance and regularity of campus daily
life.
曹毅说:“GPA和吃饭的相关系数是0.128，和洗澡的相关系数是0.157。”两者均表明学业成绩与校园日常生活规律性之间存在很强的正相关关系。
The students with better performance are prone to overcome difficulties and
stick to their routine even on chilly mornings. The less the students are
affected by weather conditions in keeping life routines, the more
self-disciplined they are and the better grades they can get, said Gao Jian,
another researcher on the study.
“表现好的学生更容易克服困难，即使在寒冷的早晨也会坚持自己的习惯。”另一名研究人员高建说，“在日常生活中受到天气影响越小的学生，他们就越自律，成绩也越好。”
We are not aiming to ask all the students to live according to a same
timetable, but to help school administrators detect undesirable, abnormal
behavior and give them proper intervention in time. For example, students who
are addicted to online games often have an irregular lifestyle and those who
always live alone are prone to depression, Zhou added.
周涛说：“我们的目标不是让所有的学生都按照同样的习惯生活，而是帮助学校管理者发现不良的、不正常的行为，及时给予适当的干预。例如，沉迷于网络游戏的学生往往生活方式不规律，独自生活的学生更容易抑郁。”
