The NPPCDS consists of two modules: an automatic correction module and a graphical display module. The automatic correction module automatically corrects the T213 NPP at regularly scheduled time intervals, while the graphical display module interacts with users to display the T213 NPP and its correction results. The system helps forecasters extract the most relevant information at a quick glance without extensive post-processing. It is simple, easy to use, and computationally efficient, and has been running stably at Huludao Meteorological Bureau in Liaoning Province of China for the past three years.

文摘This paper presents the development of numerical prediction products(NPP) correction and display system(NPPCDS) for rapid and effective post-processing and displaying of the T213 NPP(numerical prediction products of the medium range numerical weather prediction spectral model T213L31) through instant correction method.

The automatic correction module automatically corrects the T213 NPP at regularly scheduled time intervals, while the graphical display module interacts with users to display the T213 NPP and its correction results.

文摘为探究预干燥方式对瞬时压差膨化(instant controlled pressure drop,DIC)整果香菇脆品质特性影响,开发即食香菇脆休闲食品,本文研究了热风干燥(hot air drying,HAD)、热泵干燥(heat pump drying,HPD)和真空冷冻干燥(vacuum freeze drying,FD)等3种预干燥方式对DIC香菇脆品质的影响。结果表明,香菇脆总干燥时间取决于预干燥方式,由低至高为:HAD-DIC<HPD-DIC<FD-DIC;平均干燥速率则与之相反。总色差由低到高为:FD-DIC<HPD-DIC<HAD-DIC。膨化度高低顺序为:HPD-DIC>HAD-DIC>FD-DIC。复水比高低顺序为:FDDIC>HPD-DIC>HAD-DIC。HAD-DIC香菇脆硬度值最高,脆度值最低;FD-DIC香菇脆硬度和脆度均较低;HPDDIC香菇脆硬度适中且脆度最高。总糖含量高低顺序为:FD-DIC>HPD-DIC>HAD-DIC。低场核磁共振(low field nuclear magnetic resonance,LF-NMR)结果表明,相比于FD和HAD预干燥,HPD后的香菇疏松结合水和不易流动水所占比例较高,紧密结合水比例较低,有利于DIC瞬间泄压时水分闪蒸,为香菇膨化提供充足驱动力。综合考虑,香菇脆最适预干燥方式为HPD。
