Background:Light at night(LAN)has become a concern in interdisciplinary research in recent years.This global interdisciplinary study aimed to explore the exposure-lag-response association between LAN exposure and lung cancer incidence.Methods:LAN data were obtained from the Defense Meteorological Satellite Program’s Operational Linescan System.Data of lung cancer incidence,socio-demographic index,and smoking prevalence of populations in 201 countries/territories from 1992 to 2018 were collected from the Global Burden of Disease Study.Spearman correlation tests and population-weighted linear regression analysis were used to evaluate the correlation between LAN exposure and lung cancer incidence.A distributed lag nonlinear model(DLNM)was used to assess the exposure-lag effects of LAN exposure on lung cancer incidence.Results:The Spearman correlation coefficients were 0.286-0.355 and the population-weighted linear regression correlation coefficients were 0.361-0.527.After adjustment for socio-demographic index and smoking preva-lence,the Spearman correlation coefficients were 0.264-0.357 and the population-weighted linear regression correlation coefficients were 0.346-0.497.In the DLNM,the maximum relative risk was 1.04(1.02-1.06)at LAN exposure of 8.6 with a 2.6-year lag time.After adjustment for socio-demographic index and smoking prevalence,the maximum relative risk was 1.05(1.02-1.07)at LAN exposure of 8.6 with a 2.4-year lag time.Conclusion:High LAN exposure was associated with increased lung cancer incidence,and this effect had a specific lag period.Compared with traditional individual-level studies,this group-level study provides a novel paradigm of effective,efficient,and scalable screening for risk factors.

Enhanced Anti-Wear Property of Low Viscosity Engine Oil for Sequence IVB Engine Test Meeting the GF-6 Specification

引用

China Petroleum Processing & Petrochemical Technology 2019年第2期21卷 95-102页

作者： Xie Xin Jia Qiulian zhang jianrong SINOPEC Research Institute of Petroleum Processing

The purpose of this research is to determine the anti-wear capability of new advanced low viscosity engine oil to meet the Sequence IVB requirement of ILSAC GF-6 specification, which envisages that the first certification will be realized in 2020. The anti-wear performance of the aged candidate GF-6 engine oils was evaluated using the laboratory bench test rigs such as the Falex Pin & Vee Block test machine and the high frequency reciprocating rig (HFRR). The worn surfaces were analyzed by X-ray photoelectron spectroscopy (XPS). The remarkable anti-wear performance of the developed GF-6 engine oil was also confirmed in the Sequence IVB test. The results indicate that by appropriately selecting and balancing the calcium detergent additives the wear loss of cam and tappet determined in the Sequence IVB test at low temperature could be significantly reduced. The time for occurrence of the intersection of the base and acid values corresponds well with the increase of wear of cam tappet of the IVB engine test.

Rare Metals 2010年第4期29卷 355-360页

Spherical indium tin oxide （ITO） nanoparticles were synthesized by combustion method using citric acid as fuel and nitrates as oxidizer. The obtained ITO nanoparticles were characterized by TG-DSC, FT-IR, XRD, BET, TEM, and SEM. The ITO nanoparticles grew steadily with the increase of heat treatment temperature, and the 700~C calcined particles had a crystallite size of 25.3 nm and a specific surface area of 26.1 m2.g i The avoidance of chlorine ions in the synthesis process decreases particle agglomeration and promotes powder densification. The 900~C sintered pellet had a density of 67.6% of theoretical density （TD） and increased steadily to 97.3% for the 1400℃ sintered ceramics, respectively.

Effects of Gasoline with Ester Additives on the Swelling Behavior of Rubbers

引用

China Petroleum Processing & Petrochemical Technology 2018年第1期20卷 44-51页

作者： Wang Pengfei Yang He Song Haiqing zhang jianrong SINOPEC Research Institute of Petroleum Processing Beijing 100083

In this study, gasoline was blended with dimethyl carbonate, ethyl acetate or methyl acetate respectively with four different volume fraction, i.e. 1%, 3%, 5% and 10%. The nitrile-butadiene rubber (NBR), fluorocarbon rubber (FKM), and Silastic were prepared for the immersion tests. To assess the performance of the three ester additives, the changes in the weight and volume of these three elastomers during the immersion tests with different gasoline samples were studied. The results showed that gasoline blended with the ester additives could lead to serious swelling problem for the elastomer materials which were widely used in the vehicle manufacture industry. The seal ability of elastomer materials would also be impaired by being exposed in the ester additives-gasoline blending for a long time.

Study on Tribology Performance of Different Lubricant Additives under Atmospheric Pressure and High Vacuum Conditions

引用

China Petroleum Processing & Petrochemical Technology 2016年第4期18卷 81-91页

作者： Peng Qian Huang Zhiyang Yang He Song Haiqing zhang jianrong Research Institute of Petroleum Processing SINOPEC

By using PAO-10 as the base oil, the tribological behavior of 11 additives under high vacuum condition was evaluated. By adopting some surface analytical instruments, such as scanning electron microscopy(SEM), energy dispersive spectroscopy(EDS) and X-ray photoelectron spectroscopy(XPS), the tribological mechanisms of these additives were studied. In air, O_2 can react with metal to form metal oxide that can protect the surfaces of rubbing pair during the tribological tests. According to the theory of the competitive adsorption, the function of some active elements is weakened. In a vacuum environment, the additives contributed more to the lubrication performance. The sulfur-containing additives could react with Fe to produce Fe Sx and "M—C" bonds("M" represents metal). They both had contributions to the lubrication. As for the phosphorus-containing additives, they only generated the phosphates during the tests. When the sulfur and phosphorus-containing additives were applied, the generated phosphates and Fe Sx had the primary contribution to the lubrication performance during the tests.

针对王庄煤矿综放工作面回撤期间面临的工序繁琐、劳动强度大、支护材料难以回收重复利用、支护耗材易燃等难题,采用掩护支架代替架设圆木木桩、枕木木垛支护的全断面掩护支护,从数值模拟分析得出木垛和单体支柱的支护强度无法满足待支护区域对平均支护强度的要求,采用全断面掩护支护可以降低顶板下沉量,防止帮部裂隙的扩展贯通和保证煤岩体的完整性,使回撤通道得到很好的控制;将原有撤架工艺优化为绞车牵引全断面掩护撤架工艺,提高了回撤顶板支护机械化程度与作业安全性,缩短了回撤工期、减人提效。

环境冲突是旅游地主客冲突的主要内容之一,探寻环境冲突的影响因素对于旅游地空间规划和冲突化解有重要理论与现实意义。该文以五台山景区为例,通过扎根理论与定性比较分析相结合的混合研究方法探究了环境冲突在居民与游客2个群体中的主观呈现,并进一步分析了引发感知环境冲突的多重路径。主要得到以下结论:(1)居民与游客感知旅游地环境冲突类型具有同一性与异质性,景区管理混乱是2个群体冲突感知同一性的具体表达,异质性则体现在居民更多关注游客不当行为,而游客则更重视旅游地环境功能单一;(2)以节假、秩序与设施为代表的核心冲突条件表明,主观空间占有与体验权的错位是引致2个群体感知环境冲突产生的关键要素;(3)规范失效是导致文化旅游地环境冲突的特殊因素,在居民和游客群体中均有表现。
