| 1 | A design study on the CSNS LEBT pre-chopper显示文摘The China Spallation Neutron Source (CSNS) front end incorporates a pre-chopper in the Low Energy Beam Transport line (LEBT) that will remove a 530 ns section of beam at approximately 1 MHz rate, which is the RF frequency of the ring at injection. It's one of the most critical devices for properly controlling the injecting beam loss. Physical designing of the pre-chopper is carried out, and the RFQ itself is used as the beam dump of the chopper system. In order to examine the reliability of the pre-chopper design, the beam study of a similar chopper system is successfully performed. The results of physical design and experiments are presented. | LIU HuaChang OUYANG HuaFu PENG Jun HUANG Tao GONG KeYun XU TaoGuang FU ShiNian | 2011 | Science China(Physics,Mechanics & Astronomy)2011，54，S2： | 3 |
| 2 | The R&D status of DTL for CSNS显示文摘The China Spallation Neutron Source (CSNS) is a spallation neutron research facility being built at Dongguan in Guangdong Province. The 324 MHz Alvarez-type Drift Tube Linac will be used to accelerate the H- ion beam from 3 to 80.0 MeV with peak current 15 mA. The R&D of a prototype structure at the low energy section of DTL is taking place at IHEP. The first unit tank ~2.8 m in length and 28 drift tubes containing electromagnetic quadrupoles are developed. The SAKAE coils are applied in the fabrication of the electromagnetic quadrupoles. This paper introduces the R&D status of the tank and 28 drift tubes. The fabrication process and measurement results of the electromagnetic quadrupoles of special interest are also presented. | YIN XueJun GONG KeYun PENG Jun SONG Hong XIAO YongChuan LI AHong LIU Lei FU ShiNian | 2011 | Science China(Physics,Mechanics & Astronomy)2011，54，S2： | 3 |
| 3 | Correlation of periodontal diseases with intracranial aneurysm formation:novel predictive indicators显示文摘Background:We investigated whether periodontal diseases,specifically,periodontitis and gingivitis,could be risk factors of the incidence of intracranial aneurysms(IAs).Methods:We performed a case–control study to compare the differences in the periodontal disease parameters of 281 cases that were divided into the IAs group and non-IAs group.All cases underwent complete radiographic examination for IAs and examination for periodontal health.Results:Comparing with those in the non-IAs group,the cases in the IAs group were older(53.95±8.56 vs 47.79±12.33,p<0.001)and had a higher incidence of hypertension(76 vs 34,p=0.006).Univariate logistic regression analysis revealed that age(>50 years)and hypertension were predictive risk factors of aneurysm formation(odds ratio[OR]1.047,95%confidence interval[95%CI]1.022–1.073,p<0.001 and OR 2.047,95%CI 1.232–3.401,p=0.006).In addition,univariate and multivariate logistic regression analyses showed that the parameters of periodontal diseases,including gingival index,plaque index,clinical attachment loss,and alveolar bone loss,were significantly associated with the occurrence of IAs(all p<0.05).For further statistical investigation,the parameters of periodontal diseases were divided into four layers based on the quartered data.Poorer periodontal health condition(especially gingival index>1.1 and plaque index>1.5)had the correlation with IAs formation(p=0.007 and p<0.001).Conclusion:Severe gingivitis or periodontitis,combining with hypertension,is significantly associated with the incidence of IAs. | Keyun Liu Jia Sun Lingling Shao Hongwei He Qinglin Liu Youxiang Li Huijian Ge | 2021 | Chinese Neurosurgical Journal2021，7，3： | 1 |

| 10 | Research status and hotspot analysis of body donation in China:A CiteSpace-based study显示文摘To provide references by analyzing the history,hotspot,and trend of the research in body donation,CiteSpace software was used to conduct a co occurrence network analysis,and 196 articles in CNKI database were included.With the increasing number of articles in recent years,“Political and legal organizations”and“medical schools and departments”were main research institutions. | Liu Runzhu Tang Keyun Lei Shubin Li Xianmei Zhang Hanlin Ma Chao | 2021 | 解剖学杂志2021，44，S01： | 0 |
| 11 | Contributions of Chinese scholars to body donation research in international journals显示文摘Anatomical dissectionis an important part of human anatomy course and relies much on cadavers.Body donation is the primary source of cadavers used in ana tomical dissection course in China.This study aimed to systematically review the contributions of Chinese scholars to body donation research in international journals,in the 100^(th) anniversary of the foundation of Chinese Society for Anatomical Sciences.The search was conducted on May 12,2020.The searching strategy was(body or anatomy or anatomical or cadaver or cadaveric)and(donate or donation or bequest or gift or gifting)and(China or Hong Kong or Macao or Taiwan).Only English articles focusing on body donation research were included.A total of 578 articles were retrieved. | Zhang Hanlin Tang Keyun Hu Xinzhi Wang Yuanzhuo Liu Runzhu Ma Chao | 2021 | 解剖学杂志2021，44，S01： | 0 |
