[Objectives]The changes in the nutrient contents and texture of pickled Huangzhou radish with pickling time were studied to further improve its edible value and improve its sensory evaluation.[Methods]Huangzhou radish as a raw material was pickled,and exploration was conducted through the following aspects:with the extension time of pickling time,the changes in nutrient contents such as reducing sugars,free amino acids and ascorbic acid were detected in pickled Huangzhou radish,and the changes in the texture characteristics of pickled Huangzhou radish such as hardness,viscosity,elasticity,recoverable deformation,compression power and chewiness were detected.[Results]As the pickling time became longer,the reducing sugar content in pickled Huangzhou radish gradually increased,and when the pickling time exceeded 13 d,the reducing sugar content showed a downward trend;the ascorbic acid content gradually decreased,and the decreasing rate was relatively lower after the pickling time exceeded 7 d;and the amino acid content first increased and then decreased,and when the pickling time exceeded 13 d,the content exhibited basically no *** hardness of the radish gradually decreased;the viscosity first decreased and then slowly increased;the recoverable deformation first increased and then decreased;the elasticity first increased and decreased;and the chewiness first increased and then *** this experiment,it is concluded that the pickled Huangzhou radish has richer nutrients and the best taste when the pickling time is 7-10 d.[Conclusions]This study provides a theoretical reference for producing and processing pickled Huangzhou radish,improving the quality of pickled Huangzhou radish and increasing the nutritional value of the product.

为提高高速公路主线出口匝道区域的行车安全性,基于HRV指标量化分析该区域的驾驶负荷特性和影响因素。分析了交通标志设计方案对主线出口匝道区域交通安全影响特性。采用HRV指标对驾驶负荷进行量化分析,同时采用不同信息量的交通标志对驾驶负荷进行定量加载,以汉十高速公路沿线匝道区为场景,设计并开展了主线出口匝道区域驾驶负荷的实车道路试验,采集不同试验场景下多个驾驶人的生理指标和驾驶特性。结果表明,交通标志信息量可以作为认知负荷加载的方式。从2 km到500 m到出口位置的预告标志,表征驾驶负荷的HRV指标呈先下降后上升的趋势。驾驶人在通过主线出口匝道区域不同路段时的行驶车速的变化趋势与驾驶负荷强度的变化趋势具有较好的一致性。
