| 1 | Size and elemental composition of dry-deposited particles during a severe dust storm at a coastal site of Eastern China显示文摘Dry-deposited particles were collected during the passage of an extremely strong dust storm in March, 2010 at a coastal site in Qingdao(36.15°N, 120.49°E), a city located in Eastern China. The size, morphology, and elemental composition of the particles were quantified with a scanning electron microscope equipped with an energy dispersive X-ray instrument(SEM–EDX). The particles appeared in various shapes, and their size mainly varied from 0.4to 10 μm, with the mean diameters of 0.5, 1.5, and 1.0 μm before, during, and after the dust storm, respectively. The critical size of the mineral particles settling on the surface in the current case was about 0.3–0.4 μm before the dust storm and about 0.5–0.7 μm during the dust storm. Particles that appeared in high concentration but were smaller than the critical size deposited onto the surface at a small number flux. The elements Al, Si and Mg were frequently detected in all samples, indicating the dominance of mineral particles. The frequency of Al in particles collected before the dust storm was significantly lower than for those collected during and after the dust storm. The frequencies of Cl and Fe did not show obvious changes, while those of S, K and Ca decreased after the dust arrival. These results indicate that the dust particles deposited onto the surface were less influenced by anthropogenic pollutants in terms of particle number. | Hongya Niu Daizhou Zhang Wei Hu Jinhui Shi Ruipeng Li Huiwang Gao Wei Pian Min Hu | 2016 | Journal of Environmental Sciences2016，28，2： | 4 |
| 2 | Teaching Reform for HarmonyOS Mobile Application Development显示文摘In recent years,the IT industry in China has developed rapidly and made remarkable achievements.However,there is still a big gap between China and foreign countries in the core fields of information technology,such as system hardware and software platform.Currently,foreign countries have gradually raised the restrictions of information technology in China,and even added many domestic enterprises to the restricted list,which has rung the alarm to the information security of the country.Therefore,in order to break through the foreign technology blockade and find a unique way in independent software and hardware platform,it is urgent to carry out the curriculum construction and talent training mechanism on core software and hardware platform.HarmonyOS is a“future-oriented”distributed operating system developed by Huawei.It proposes a distributed concept based on the same system capability and adapts to a variety of terminal forms,and supports a variety of terminal devices such as mobile phones,watches and smart screens.Our course on HarmonyOS aims to increase the theoretical knowledge of the core independent software and hardware platform.In the course,we exploit our teaching reform experience in the course of“Mobile Application Development”,and investigate the teaching mechanism of HarmonyOS to contribute to the rapid development of information technology and ecological construction in China. | Ruipeng Gao Weiwei Xing Haoyue Zhao Dan Tao | 2021 | 计算机教育2021，，12： | 1 |
| 3 | Ideological and Political Education in Harmony OS Application Development Course显示文摘The emergence of the Harmony operating system independently developed by Huawei has provided new opportunities and challenges for the development of our country’s information industry.This paper mainly introduces how to combine ideological and political education with mobile devices software development via Harmony OS development courses,aiming to cultivate students’ability to develop applications under the Harmony OS operating system independently or in groups,as well as achieving the patriotism and national mission. | Ruipeng Gao Xinrui Wang Weiwei Xing Dan Tao | 2022 | 计算机教育2022，，12： | 0 |
| 4 | Teaching Reform for Mobile Application Development with Industrial Projects,Double Instructors,and Automatic Assessments显示文摘Mobile Application Development is a well-known undergraduate specialized course majoring in Computer Science and Software Engineering.Since it is a rapid developing technique and requires extensive project samples to help understand,current teaching mechanism has still limitations in rare real project examples,outdated course contents,and lack of automatic assessment platforms.In order to improve the teaching effects and cultivate students’practical ability,we employ this teaching reform with industrial projects,double instructors,and automatic assessment platform to allow students participating in every course process.We aim to improve students’practical and collaboration ability during conducting the project spontaneously,and cultivate their awareness of self-learning and lifelong learning.Our classroom feedback has demonstrated that this teaching reform is effective on improving students’practical abilities,learning initiatives and comprehensive qualities. | Ruipeng Gao Weiwei Xing Dan Tao | 2020 | 计算机教育2020，，12： | 0 |
