硅土充填高聚物的性能研究

探讨了硅土的矿物学特性及其对充填高聚合物的影响，研究表明，天然超细粒度（０．０１－０．００１ｍｍ）复合矿物的及独特的粒－片叠置结构是导致硅土在高聚合物中具有良好增强性能的主要原因。     

热处理时间对IT0薄膜显微组织及光电性能的影响

采用溶胶一凝胶法在玻璃基体上制备了ITO薄膜,研究了后续热处理时间对ITO薄膜显微组织及光电性能的影响。研究结果表明:随着热处理时间的延长,ITO薄膜的微观形貌发生了很大的变化,出现了小丘生长并伴随着回复与再结晶过程,严重影响了ITO薄膜的光电性能。

Intercultural sensitivity among university students: measurement of the construct and its relationship with international mobility programmes / Sensibilidad intercultural de los estudiantes universitarios: medición del constructo y su relación con los programas de movilidad internacional

The purpose of this study was to validate the IDI (Intercultural Development Inventory) and to assess the impact of international mobility programmes on the intercultural sensitivity of university students. For this, a quasi-experimental study was carried out using a longitudinal design of repeated pre-test and post-test measures, with an experimental group of students who carried out international mobility programmes and a control group of students who did not. The sample consisted of 3,047 university students. The inventory yielded a five-factor structure (negation/defence, minimization, reversion, acceptance/adaptation and encapsulated marginality) with alpha coefficients ranging from .82 to .91, revealing adequate reliability and validity. The results indicate the effectiveness of the IDI to measure intercultural sensitivity. Although the post-test scores are higher than the pre-test scores for both groups, there are significant differences in favour of the experimental group (p = .000) in all factors except the negation/defence stage. The conclusions focus on the implications of this study for curriculum development and policy at an educational level.

从《吴问》论重税先亡看孙武的民本思想

临沂银雀山汉简《吴问》记载了孙武根据晋国六卿自定地亩的大小,收取赋税的轻重,预言其败亡先后,劝谏吴王厚爱其民的史事,表现了孙武以民为本的军事思想。这与孙武后来谏阻吴王“民劳,未可”,暂时不要攻楚入郢和六年后“王必欲大伐,必得唐蔡乃可”的做法,以及《孙子兵法》中提出的“惟民是保”思想是一脉相承的。孙武在军事上以民为本的思想至今仍有现实意义。     

新型磷酸酯甜菜碱两性表面活性剂物化性能研究

研究了一类新型的两性表面活性剂-3-[N-(3-烷氧基-2-羟丙基)-N，N-二甲基铵]-2-羟丙基酸性磷酸酯甜菜碱(AHDHPB)的物化性能，包括两性特征、泡沫性能、表面张力、临界胶束浓度、临界溶解温度。研究结果表明，这类表面活性剂在pH=4．0～7．0范围内显示两性特征；在pH=5左右具有优良的发泡力、泡沫持久性和室温下优良的水溶性；其临界胶束浓度(cmc)和表面张力(γcmc)比阴离子表面活性剂十二烷基硫酸钠(SDS)和阳离子表面活性剂十二烷基三甲基溴化铵(DTAB)要低，属于高效表面活性剂。     

溶剂束缚球假说对稀溶液依数性的解释

目的：从溶质和溶剂粒子之间的作用力和溶液的凝聚态解释稀溶液依数性。方法：根据拉乌尔定律提出后100多年来发现的实验事实，分析溶质和溶剂粒子的受力情况和凝聚态。结果：提出了“溶剂束缚球”假说，成功地解释了稀溶液依数性产生的原因，指出了拉乌尔定律错误的根源。结论：溶剂束缚球和分子平均缔合度是产生稀溶液依数性的原因。
