This study uses data provided by the National Meteorological Information Center of China, Japan Meteorological Agency (JMA) and National Oceanic Atmospheric Administration (NOAA) Physical Sciences Laboratory of the USA to analyze a cold air weather process at the beginning of January 2021. Synoptic analysis is mainly used to summarize synoptic laws or patterns based on observational data, and describe and infer weather processes. The main conclusions are as follows: The cold air travels south along the northwest path, affecting most of China. During the cold wave process, the first cold air is weak, which has a certain cooling effect on northern China. The second cold air was guided by the low vortex, the accumulation in the transverse groove of Mongolia was strengthened, and the cooling effect was significant. The southwest jet showed an increasing trend, and the water vapor transport conditions were good. However, due to the relatively gentle southern branch system, the warm and humid air flow was weak and the precipitation level was small. The purpose of this study is to better understand a large-scale cold air weather process in January 2021 in China.

The smallest cyclic ammonium salt reported to date, N,N-dimethylpyrrolidinium tetrafluoroborate (P11-BF4), was successively synthesized using a synthesis route without metal ions and halogen ions, then investigated as the electrolyte with Propylene carbonate in EDLCs. The electrochemical characteristics of EDLCs assembled by 1 mol/L P11-BF4/PC paired with activated carbon electrodes were compared to traditional electrolytes. P11-BF4 has proven to have superior voltage resistance by using cyclic voltammetry and constant current charge-discharge testing. Moreover, P11-BF4 exhibits a more brilliant rate performance due to its high conductivity. These results demonstrate that P11-BF4 is an ideal electrolyte to improve the energy density and power density of supercapacitors.

A SINS/GNSS location method based on factor diagram is proposed to meet the requirement of accurate location of substation construction personnel. In this paper, the inertial autonomous positioning, carrier motion information acquisition and satellite positioning technologies are integrated. The factor graph method is adopted to abstract the measurement information received by inertial navigation and satellite into factor nodes, and the state information into variable nodes, so as to construct the SINS/GNSS construction personnel positioning fusion factor graph model. The Gauss-Newton iterative method is used to implement the recursive updating of variable nodes, and the optimal estimate of the location information of the construction personnel is calculated, which realized the high precision location of the construction personnel. The factor graph method is verified by pedestrian navigation data. The results show that the factor graph method can continuously and stably output high-precision positioning results, and realize non-equidistant fusion of SINS and GNSS. The positioning accuracy is better than Kalman filter algorithm, and the horizontal positioning accuracy is less than 1 m. Therefore, the factor graph method proposed can provide accurate location information for substation construction personnel.

目的探讨钎维蛋白原、载脂蛋白比值与冠状动脉病变程度的相关性。方法选取2014年3月至2015年3月符合诊断标准的冠状动脉病变患者120例，其中稳定型心绞痛（SAP组）40例，不稳定型心绞痛（UAP组）40例，急性心肌梗死（AMI组）40例。选择同期体检者40例为对照组。比较各组纤维蛋白原、载脂蛋白比值与冠状动脉病变程度的相关性。结果纤维蛋白原：AMI组与SAP组（四分距0．42比O．29）、AMI组与对照组（四分距0．42比0．51）、UAP组与SAP组（四分距0．61比0．29）、UAP组与对照组（四分距0．61比0．51）比较差异均有统计学意义（P〈0．05）。载脂蛋白比值：AMI组与SAP组（四分距0．28比O．41）、AMI组与对照组（四分距0．28比0．42）、UAP组与SAP组（四分距0．29比0．41）、UAP组与对照组（四分距0．29比0.42）比较差异均有统计学意义（P〈0．05）。结论纤维蛋白原可以作为冠心痛的独立危险因子，而且可以作为评估冠状动脉病变的程度的一个指标。载脂蛋白比值可以用来预测冠心病风险，并且可以评估冠心病及冠状动脉病变程度。
