| 1 | 哈尔滨市寒冷月份空气质量指数与空气污染物的相关性显示文摘以哈尔滨市环保局公布的2014年1—2月份市区内空气质量指数(AQI)实时监测数据为基础,每日对监测数据进行收集整理,得到了AQI的实时值以及PM2.5、PM10、CO、SO2、NO2质量浓度和臭氧1 h质量浓度(O3(1 h))、臭氧8 h质量浓度(O3(8 h));运用相关性分析、主成分回归分析及通径分析方法,分析各空气污染物对AQI的影响程度。结果表明:AQI与PM2.5、PM10、CO、SO2、NO2呈显著正相关,AQI与O3(1 h)、O3(8 h)呈显著负相关;空气污染物间存在严重的多重共线性。根据相关性分析结果,建立AQI与空气污染物的主成分回归模型,模型通过检验。通径分析结果表明:PM2.5对AQI的直接作用及总作用,均最大;PM2.5通过CO对AQI的间接作用,均大于其他污染物通过CO对AQI的间接作用;PM2.5对AQI的变化,起到了决定性的影响作用。 | 张燕杰 Zeyi Lin 郑煜 | 2015 | 东北林业大学学报2015，43，11： | 8 |
| 2 | The Solar Upper Transition Region Imager(SUTRI)Onboard the SATech-01 Satellite显示文摘The Solar Upper Transition Region Imager(SUTRI)onboard the Space Advanced Technology demonstration satellite(SATech-01),which was launched to a Sun-synchronous orbit at a height of~500 km in 2022 July,aims to test the on-orbit performance of our newly developed Sc/Si multi-layer reflecting mirror and the 2k×2k EUV CMOS imaging camera and to take full-disk solar images at the Ne VII 46.5 nm spectral line with a filter width of~3 nm.SUTRI employs a Ritchey-Chrétien optical system with an aperture of 18 cm.The on-orbit observations show that SUTRI images have a field of view of~416×416 and a moderate spatial resolution of~8″without an image stabilization system.The normal cadence of SUTRI images is 30 s and the solar observation time is about16 hr each day because the earth eclipse time accounts for about 1/3 of SATech-01's orbit period.Approximately15 GB data is acquired each day and made available online after processing.SUTRI images are valuable as the Ne VII 46.5 nm line is formed at a temperature regime of~0.5 MK in the solar atmosphere,which has rarely been sampled by existing solar imagers.SUTRI observations will establish connections between structures in the lower solar atmosphere and corona,and advance our understanding of various types of solar activity such as flares,filament eruptions,coronal jets and coronal mass ejections. | Xianyong Bai Hui Tian Yuanyong Deng Zhanshan Wang Jianfeng Yang Xiaofeng Zhang Yonghe Zhang Runze Qi Nange Wang Yang Gao Jun Yu Chunling He Zhengxiang Shen Lun Shen Song Guo Zhenyong Hou Kaifan Ji Xingzi Bi Wei Duan Xiao Yang Jiaben Lin Ziyao Hu Qian Song Zihao Yang Yajie Chen Weidong Qiao Wei Ge Fu Li Lei Jin Jiawei He Xiaobo Chen Xiaocheng Zhu Junwang He Qi Shi Liu Liu Jinsong Li Dongxiao Xu Rui Liu Taijie Li Zhenggong Feng Yamin Wang Chengcheng Fan Shuo Liu Sifan Guo Zheng Sun Yuchuan Wu Haiyu Li Qi Yang Yuyang Ye Weichen Gu Jiali Wu Zhe Zhang Yue Yu Zeyi Ye Pengfeng Sheng Yifan Wang Wenbin Li Qiushi Huang Zhong Zhang | 2023 | Research in Astronomy and Astrophysics2023，23，6： | 1 |

| 4 | A Case of Corneoscleral Dellen after Medial Rectus Recession Combined with Pterygium Resection in Right Eye显示文摘Purpose:A case of corneoscleral dellen after medial rectus recession combined with pterygium resection was reported. Methods: Case report Results:A male patient aged 48 years had ghost for 1 year after acoustic neuroma resection.The patient was diagnosed with rectus paresis in the right eye. He successfully underwent medial rectus recession combined with pterygium resection. A corneoscleral dellen with a size of 2 ×2 mm was observed at 20 d postoperatively. The thinnest cornea was 147 um, diagnosed as corneoscleral dellen, which was cured after undergoing corneal limbal stem cell transplantation with conjunctival flap. Conclusion:Corneoscleral dellen is noninfectious corneoscleral ulcer caused by complex reasons.Most cases recovered by using artificial tears,antibiotic ointment and eye wrap,and other patients required corneal limbal stem cell transplantation with conjunctival flap, even keratoplasty. It is recommended that the patients with strabismus combined with pterygium underwent conjunctival flap transplantation at early stage to prevent the incidence of surgical complications. | Shibin Lin Zeyi Li Xingkai Zhan Jianhao Cai | 2012 | Eye Science2012，27，4： | 0 |
| 5 | A brief review of metamaterials for opening low-frequency band gaps显示文摘Metamaterials are an emerging type of man-made material capable of obtaining some extraordinary properties that cannot be realized by naturally occurring materials.Due to tremendous application foregrounds in wave manipulations,metamaterials have gained more and more attraction.Especially,developing research interest of low-frequency vibration attenuation using metamaterials has emerged in the past decades.To better understand the fundamental principle of opening low-frequency(below 100 Hz)band gaps,a general view on the existing literature related to low-frequency band gaps is presented.In this review,some methods for fulfilling low-frequency band gaps are firstly categorized and detailed,and then several strategies for tuning the low-frequency band gaps are summarized.Finally,the potential applications of this type of metamaterial are briefly listed.This review is expected to provide some inspirations for realizing and tuning the low-frequency band gaps by means of summarizing the related literature. | Kai WANG Jiaxi ZHOU Dongguo TAN Zeyi LI Qida LIN Daolin XU | 2022 | Applied Mathematics and Mechanics(English Edition)2022，43，7： | 0 |
