音乐表演中的意会认知,是以音乐表演意会知识为认知对象的求知探索,英国哲学家波兰尼的意会知识论为该研究提供了理诰依据,证实了音乐中“只可意会,不可言传”的内容是一种客观存在,这种存在形态多样且作用巨大。本文从音乐表演的文本对象、技术经验、觉知审美三个维度,将音乐表演中意会认知的对象与意会认知的形式进行有机结合而展开探讨,从主观的求知中找寻客观的存在,又从客观的朦胧中感知验证意会认知,试图厘清音乐表演中意会认知的研究路径。

In this study, five 2 -4 years old healthy female poodles were selected and mated after spontaneous estrus for pregnancy diagnosis with external observa- tion, human chorionic gonadotropin colloidal gold rapid test strips （human early pregnancy test strips）, ultrasonic diagnosis and blood routine examination. Accord- ing to the results, female dogs showed abdominal circumference increment and mammogenesis from a month post-mating to parturition and lactated before parturi- tion. At 5, 6, 7, 15, 25 and 35 d post-mating, pregnancy diagnosis with human chorionic gonadotropin colloidal gold rapid test strips showed negative results. Hu- man early pregnancy test strips can not be used for pregnancy diagnosis in female dogs. Currently, ultrasonic method is the most accurate method to diagnose preg- nancy in female dogs, and the optimal diagnosis time is the 30th d post-mating. External observation and blood routine examination can be used as auxiliary methods to diagnose pregnancy in female dogs.

利用溶液洗涤法和高温真空干燥处理法,在水溶液中对高镍LiNi0.8Co0.1Mn0.1O2(LNCM)三元材料进行洗涤,并进行高温真空干燥处理。通过化学分析法、BET测试仪、XPS和SEM分别对高镍LNCM三元材料的pH值、可溶锂含量、BET、物相结构和表面形貌进行了测试,重点研究了水洗时间对高镍LNCM三元材料物理和电化学性能的影响。结果表明,采用水洗和高温真空干燥处理工艺,可有效去除高镍LNCM三元材料表面残余Li2CO3和LiOH,其原理主要是基于Li2CO3和LiOH的溶解机理,而非物理摩擦洗涤机理;随着水洗时间继续延长,水洗液的pH值和材料的比表面积缓慢增加,而材料表面残碱、材料的放电容量、循环保持率和倍率性能却逐步降低。因此选择水洗时间为2 min最优,此时水洗液的pH值增加至12.04,材料的BET增加至0.3043 m^2/g;材料表面的Li2CO3含量降低为0.1043%,LiOH含量降低为0.1382%;放电容量为203.8 mAh/g;1 C循环50圈后,材料的容量保持率为86.23%;5 C倍率下放电,仍保持有2 C初始容量的84.5%。
