摘要：Experimental design （DOE） was employed to precisely determine the content of rubidium in chloride type brine of Qionglai （A city in Sichuan province, southwest of China） using atomic absorption spectrometry （AAS） technique. From the statistical analysis of six factors, it was found that K＋ and CI- were the significant interfering elements for the determination of rubidium. A model was established to eliminate the interference effects of K＋ and Cl . The experimental results indicate that, under the optimal conditions, the developed method for the rubidium determination possesses the advantages of low detection limit （0.019 μg·mL^-1 at a significant level of 0.05） and higher recovery （97.2%--103.4%）.

摘要：人类有商品生产,便有商业广告;人类有社会组织,便有公益广告。广告作为推广产品、服务或理念、信息的一种传播活动,因是“有所为而为”,必然要追求传播的效果。为了取得尽可能好的传播效果,自古以来,不论是商业广告,还是公益广告,事实上都是非常重视广告修辞的。作为一种积极的语言活动和功利性很强的社会传播活动,广告修辞应该坚持也必须坚持一定的社会伦理原则,这就是“真”“善”“美”原则。

摘要：The secretion of melatonin(MT)is obviously different in the younger and the senior sectors of the population,and the maximum plasma concentration of seniors is only half of that in the younger population *** exogenous MT can be supplied to senior citizens based on the secretion rate and amount of endogenous MT in the younger population by a bio-mimetic drug delivery system(DDS),an improved therapeutic effect and reduced side effects can be *** upon this hypothesis,the pharmacokinetic parameters of MT,namely,the absorption rate constant(ka),the elimination rate constant(ke),and the ratio of absorption rate(F)to the apparent volume of distribution(V)were obtained by a residual method depending on the plasma concentration curve of immediate release preparations in the healthy younger *** dose-division method was applied to calculate the cumulative release profiles of MT achieved by oral administration of a controlled release drug delivery system(DDS)to generate plasma MT profiles similar to the physiological level-time *** in vivo release of MT deduced from the healthy younger population physiological MT profiles as the pharmacokinetic output of the bio-mimetic DDS showed a two-phase profile with two different zero order release rates,namely,4.919μg/h during 0-4 h(r=0.9992),and 11.097μg/h during 4-12 h(r=0.9886),*** the osmotic pump type of DDS generally exhibits a good correlation between in vivo and in vitro release behaviors,an osmotic pump controlled delivery system was designed in combination with dry coating technology targeting on the cumulative release characteristics to mimic the physiological MT profiles in the healthy younger *** high similarity between the experimental drug release profiles and the theoretical profiles(similarity factor f_(2)>50)and the high correlation between the predicted plasma concentration profiles and the theoretical plasma concentration profiles(r=0.9366,0.9163,0.9264)ind

摘要：我国江南私家园林因其自然景观与人文景观的和谐统一而具有极高的文化和艺术价值,创造出了当时以"退隐"为特点的最佳人居环境。通过对江南私家园林在空间组织、意境表现手法、理水艺术三方面的景观特色解读,结合具体创作实践,探讨了江南私家园林造园艺术在现代居住小区中发展与创新的方式,从而为塑造符合现代审美需求的居住区环境提供了设计依据。

摘要：This paper explored the method of measuring the flow of people in a given public transportation *** theories used in this paper are mainly statistical ways of estimating the flow of people.I is hoped that this paper can be served as a tool for both theoretically study and in practice.

摘要：双减政策后基于AGIL模型为抓手构建的作业系统是将作业视作教育评价系统下一相对独立的子系统。作业系统的运行机制是把环境作为作业系统构成的生存依托,主体是作业系统运行的控制中心,作业系统的要素是作业设计、作业实施、作业反馈、作业管理。“双减”后作业系统出现主体配合环境需求积极性低、素养导向与结构化作业理念落空、资源收集与有效利用方式有限、区域特色与校本文化弱化的失衡现状。AGIL模型中的作业系统境遇是适应功能失控、目标达成功能失调、整合功能失策、潜在模式维持功能失范。作业系统功能发挥的路径是重构作业观念、重建评价反馈机制、重温学科学习规律、健全校本作业教研机制,如此才能推动作业系统功能的再平衡。

摘要：在AIGC方兴未艾的背景下,出版学视角下的生成式人工智能研究层出不穷,但以往研究多聚焦于AIGC如何赋能生产端的出版环节。本研究从消费端的阅读行为入手,以基于AIGC技术的数智人为切口,结合互动性理论,探索数智人如何赋能数字阅读实践。本研究认为,与数智人互动成为新的“人机互动”模式,且这种“人机互动”深度嵌入到了“人文互动”与“人人互动”中。在人文互动维度,数智人扮演着“知识整合者”的角色。在人人互动维度,数智人作为“新互动主体”参与其中。在数智人介入数字阅读实践后,人机互动、人文互动与人人互动这三种互动形式更加紧密相连,呈现出互补交融的价值链路,共同赋能数字阅读实践。

摘要：陶一陌教授为八台古筝而创作的古筝重奏曲《透明海》,是近年来影响较大的古筝重奏类作品,作品在艺术传承与语汇创新方面有着很好的融合与呈现。文章从作品的诗情与曲意、音乐的律动与艺术形态、音乐的音场营造与刻画,以及演奏与音韵呈现的关系等几个方面对《透明海》的音乐特征与表现意境展开分析论述,探讨古筝重奏类作品的创作和演奏。

摘要：拓片本来就是将宣纸贴在器物表面用墨拓印来记录花纹和文字,大小和形状与原物相同,除了有凹凸纹饰的器物外,甲骨文字、铜器铭文、碑刻、墓志铭、古钱币、画像砖、画像石等,都广泛使用这种办法记录。结合在后来的紫砂艺术之中,紫砂壶上面比较精美的陶刻装饰,也可以采用这样的手法来进行拓片,只不过在这一过程之中,墨汁的使用有可能会侵蚀壶体,所以名贵的紫砂壶拓片比较的少。从整体上来看这件紫砂拓片“象尊”把紫砂壶的形态如实的还原出来,同时把“象纹”的特征和印章独立的拓印出来,在辅以鲜红的签印,共同组合成一件具有独特的艺术特征和设计感的艺术作品,让我们耳目一新,特别是布展在艺术馆观看欣赏的时候,更加的能够感受到拓片的艺术魅力,而且随着时间的流逝,越发的凸显出它的弥足珍贵。

摘要：本研究利用实验法,探索信源特征、社会线索以及两者的交互作用如何影响用户对知识付费产品的内容提供者的感知信任。研究结果表明:作为信源特征的内容提供者专业度和作为社会线索的产品流行度的主效应均显著;信源特征和社会线索存在交互作用,当且仅当信源特征为高专业度时,正向社会线索对用户的感知信任才具有正向显著作用。
