为探究五常大米的优势食味品质,采用喜好度排序法和改进的适合项评级法(Rate-All-That-Apply,RATA)研究五常市内不同乡镇大米间以及与非五常产地大米的整体喜好度和感官属性差异,结合主成分分析和分类回归树对不同产地的大米进行分类。结果表明,不同产地的大米具有不同的感官特征,五常市的大米口感清甜润滑有弹性,米饭香气浓郁,食味品质明显优于其他产地的大米。并且从外观特征(饱满度、完整度和松散度)、气味特征(米饭香和清香)、滋味特征(清甜味和甜味余味)和口感特征(黏度适口性、软硬度、弹性、润滑感和细腻感)共确定了12个划分不同产地大米的关键感官属性。本研究可为五常大米感官评价体系的建立提供一定的理论依据和参考。

The occurrences of excess ^40Ar within a hydrothermal tourmaline is discussed in term of the analysis data of syngenetic muscovite and tourmaline from the Lushui hydrothermal tin-tungsten deposit in western Yunnan, China, using the ^40Ar-^39Ar stepwise heating technique. About 80% excess ^40 Ar was released in the last step when the tourmaline was fused, corresponding to a release of only -3% ^39 Ar （K）, which indicates that most excess ^40 Ar was held in the mineral lattice rather than in the channels parallel to the Z-axis. This suggests that the excess ^40 Ar was incorporated during crystallization and not diffused into the tourmaline during the post-crystallization history.

Triboelectric interfaces have already been extensively researched in the area of human–machine interaction owing to their selfsustainability,low cost,easy manufacturing,and diverse ***,some limitations(e.g.,a large number of electrodes,multiple lines,and chunks)observed in previous works hinder the further development of human–machine interaction ***,a triboelectric encoding interface is proposed by designing the reverse polarity of the tribo-layers to encode the triboelectric output *** to the inversion of the tribo-layers and the number of strip electrodes,this encoding method can realize multipurpose interactive commands by using fewer electrodes and a simple structure only in one macroscopic triboelectric device,which greatly reduces the size of the device as well as the influence of external factors on the coded signal *** a demonstration,a ring with the patterned triboelectric interface(15 mm×20 mm)achieves slide presentation and remote electric device *** addition,the triboelectric sensor has good sensitivity(1.55 V/N)and durability(>30,000 cycles).This new encoding mode shows the high applicability of the operation mode in diversified interactive applications,which provides more design strategies for intelligent control.
