苯甲酸溶剂效应的NMR考察

本文通过实验数据总结出苯甲酸溶液的化学位移δ与溶剂的介电常数ε之间存在着如下的直线方程:1/δ=A+Blgε表明,凡偏离此直线的溶液,必存在着溶质与溶剂间的分子间氢键的作用。本文还对属于这种性光的二氧六环与呲啶溶液的谱图作了仔细的讨论。

乳源木莲扦插育苗技术试验研究

本研究对乳源木莲扦插育苗试验，通过单因素试验及正交试验两种试验设计，结果表明，乳源木莲扦插育苗，宜用当年生粗壮穗条，穗长15cm，经沙藏后进行相关技术处理。说明影响乳源木莲扦插苗木成活率最主要因子是穗条年龄，其次是剂液浓度、浸液时间等三个因子。即乳源木莲扦插采用当年生穗条，粗度1cm以上，剂液浓度35ppm、浸液时间4h是提高苗木成活率最优的水平组合。     

纤维素酶在染整加工中的应用——牛仔布的高级后整理工艺探讨

为了改善牛仔布的外观和手感，并且减少生产加工中的环境污染，根据纤维素酶的作用原理，探讨了牛仔布生物法石磨的工艺，对不同纤维素酶的作用效果进行了对比与分析，并配合纤维素酶的处理选用了适当的柔软剂。经实验证明，经纤维素酶加工后的牛仔布，有良好的石磨效果，并且表面光洁，加工中无环境污染问题，配用适当的柔软剂后，不仅织物手感柔软，而且织物强力损伤小，产品档次明显提高。本实验中的工艺可供生产中使用。     

Opening the attentional window in attentional blink: An attentional cuing study

To investigate whether the functioning of cognitive control is contingent upon the attentional set in attentional blink (AB), which is a deficit in reporting the second (T2) of two targets when it occurs 200—500 ms after the first (T1) in a rapid serial visual presentation (RSVP) stream, this study examined the pattern of cuing effects in which two kinds of colored cues match (i.e., in the same attentional set) or mismatch (i.e., in a different attentional set) the color of the upcoming T2. Participants of the study were asked to monitor T1 and T2 in triple RSVP streams while the cue-T2 onset synchrony (CTOA) varied from 90 ms to 270 ms and the cue and T2 might or might not occur in the same RSVP stream as T1. Relative to the uncued condition, both the same-color and the different-color cues produced cuing effects, but the effect was larger and lasted for a longer time for the former than for the latter, whether the cue (and T2) and T1 occurred in the same stream or not. Cues with short CTOA in general enhanced T2 performance more greatly during the AB period than outside of the AB period, suggesting that cues with short CTOA could open the attentional window in advance of T2 and thus facilitate the T2 processing. These findings are consistent with the theory that the salient stimulus captures attention and opens the attentional window irrespective of the attentional set defined for the target; but the attention capture effect of the cue can be quickly overridden by the top-down control when the cue does not match the attention set. Thus both the top-down attentional control setting and the bottom-up attentional capture process function during attentional blink.
