Heavy regional precipitation(HRP)over Beijing,Tianjin,and Hebei Province(the jing–jin–Ji region or JJJ)in early October(1–10 October)is a high-impact climate event because of travel and outdoor activities by exceptionally large population during the Chinese National Day Holidays(CNDH).What causes the year-to-year variation of the HRP during early October is investigated through an observational *** is found that the HRP arises from moisture transport by southerly anomalies to the west of an anomalous low-level anticyclone over the subtropical northwestern Pacific(SNWP).Sensitivity numerical experiments reveal that the low-level anticyclonic anomaly is caused by a dipole heating pattern over tropical western and central Pacific associated with a La Niña-like SST anomaly(SSTA)pattern in the Pacific and by a negative heating anomaly over North *** latter connects the SNWP anticyclone through a Rossby wave *** ascent associated with a positive heating anomaly over the tropical western Pacific may strengthen the local Hadley Cell,contributing to maintenance of the low-level anomalous anticyclone over SNWP and extending westwards of the western Pacific subtropical high(WPSH).Therefore,both the tropical Pacific and midlatitude heating signals over North Europe may be potential predictors for HRP forecast in the JJJ region in early October.

交通成本在旅游者目的地选择中的重要性,取决于交通成本在旅游总成本中所占比例的大小。假如其它的旅游费用相对于交通费用较高,那么,交通费用在目的地选择中的重要性就被大大地减弱了。一般来说,旅游距离的增加往往引起交通费用的增加,交通费用在旅游总费用中的比重也会相应增加。因此,如果一个旅游地想吸引较远客源地的游客,就必须设法降低两地间的交通成本。

为研究燕麦超微全粉对馒头品质的影响,采用超微粉碎技术制备燕麦超微全粉,然后以不同比例的燕麦超微全粉替代小麦粉制作馒头,并采用感官评价、质构分析和图像分析的方法对馒头品质进行评价。结果表明,燕麦全粉经过超微粉碎处理后平均粒径D_(50)为17.05μm,达到超微粉级别。燕麦全粉馒头口感得到改善,本实现条件下(添加量20%以内)没有明显粗糙感觉。燕麦超微全粉的添加使主要感官指标得分均降低。馒头的硬度和咀嚼性显著增加(p<0.05),硬度和咀嚼性与感官评价总分呈极显著相关(p<0.01)。图像分析指标除气孔延长度外均差异显著(p<0.05),均与感官评价总分呈极显著相关(p<0.01)。研究表明燕麦超微全粉对馒头感官品质、质构特性及内部纹理结构均具有较大影响,燕麦超微全粉的添加量最高以10%为宜。
