通过直接计算分子配分函数并将常温下的无转动跃迁偶极矩平方近似为一常数应用到高温,计算了对称陀螺分子PH_30010-0000跃迁的高温线强度.在296K,计算的分子总配分函数与HITRAN数据库的结果符合很好,只有-0.075%的百分误差.计算的跃迁线强度在2000K和3000K的高温与HITRAN数据库的结果也吻合较好,表明分子配分函数和线强度的高温计算是可靠的.在此基础上,进一步计算了更高温度4000和5000K的跃迁线强度,报道了对称陀螺分子PH_3 0010-0000跃迁在极端高温4000和5000K的模拟光谱.计算结果对大气分子高温光谱的实验测量和理论研究均有一定的参考价值.

This paper addresses the open vehicle routing problem with time window(OVRPTW), where each vehicle does not need to return to the depot after completing the delivery *** optimization objective is to minimize the total distance. This problem exists widely in real-life logistics distribution *** propose a hybrid column generation algorithm(HCGA) for the OVRPTW, embedding both exact algorithm and metaheuristic. In HCGA, a label setting algorithm and an intelligent algorithm are designed to select columns from small and large subproblems, respectively. Moreover, a branch strategy is devised to generate the final feasible solution for the OVRPTW. The computational results show that the proposed algorithm has faster speed and can obtain the approximate optimal solution of the problem with 100 customers in a reasonable time.

The taste and odor analysis of the first,second,fourth and sixth crops of laver(Porphyra yezoensis)was obtained by electronic tongue,taste-related compound,electronic nose and gas chromatography-ion mobility spectrometer(GC-IMS).Through the detection of the electronic tongue,the pleasant tastes such as umami and richness are more intense in the early crops,which is consistent with the analysis results of free amino acids and flavored *** electronic nose can clearly distinguish between different laver ***-IMS separated and identified 36 volatile components from lavers,mainly including aldehydes,ketones,alcohols,esters,acids and aromatic *** the early harvested crops,nonanal,octanal,hexanal and benzaldehyde have a significant contribution to odor because of the high concentration and low threshold of these *** the later harvested crops,the concentration of most ketones and some aldehydes increased.1-Octen-3-ol,malondialdehyde and heptanal constituted the main odor characteristics.
