在阿贝折射仪使用中,溴代萘溶液起何作用?对
发布时间:22-07-29 来源:东北矿业网

溴代萘溶液作为折射率液的作用是使待测样品与折射棱镜表面形成良好的 光学接触,没有空隙,且有一定粘性。若设折射率液的折射 率为n2 ,待测试件折射率为nx 的话,则要求n2 > nx 。否 则 由折射定律,掠入射到待测试件光学表面的光线将无法折射 进入折射率液,更无法进入折射棱镜进而到达望远系统目镜 了,这样便无法测量待测试件的折射率了。

工学和理学有什么区别

理学进行理论学习,科学研究,以动脑为主,毕业去向到各研究所,从事教学工作。工科以操作动手为主,去向工厂。
理科和工科专业学习内容如下:
1、理学包括数学、物理学、化学、生物科学、天文学、地质学、地理科学、地球物理学、大气科学、海洋科学、力学、电子信息科学、材料科学、环境科学、心理学、统计学等16个学科类,共有31个本科专业。
在本科专业分类中,心理学属于理学,而在研究生专业分类中,心理学属于教育学。为了使两者统一,本
书将心理学类的各本科专业的得分统计到教育学排名中。
理学是基础科学,基础科学原创成果的数量和质量决定着一个国家的科学水平;因此,理学是中国科学的
生命
2、 工学包括地矿、材料、机械、仪器仪表、能源动力、电气信息、土建、水利、测绘、环境与安全、化工与制药、交通运输、海洋工程、轻工纺织食品、航空航天、武器、工程力学、生物工程、农业工程、林业工程、公安技术等21个学科类,共有79个本科专业。

工学是我国大学最大的学科,各类工学人才直接推动着我国的经济建设和工程技术领域的发展。

云南宏创矿业有限公司

没听说过,我想可能有问题因为昆明有个昆明创宏矿业物资有限公司,经营:矿山用成套设备、普通机械、仪器仪表、五金交电、高低压电器、电线电缆、金属材料、化工产品、电子产品的批发,公司名称如此接近应该注册不了。 而且云铜,云铝都是财政部控股超级大的上市公司,一个新公司怎么能夸下当老大的海口。

Qingdao Ocean University
Overview

Qingdao Ocean University's predecessor was private Qingdao University established in October 1924. In May 1930, she merged with Provincial Shandong University and became National Qingdao University.
