Abstract: based on the “Practice-pragmatism” educational concept of Yan Yuan, a scholar in the late Ming and early Qing dynasties, this paper advocates a Marxist view of reading for all from the perspective of practical theory of “Actions speak louder than words” and “XI speaks louder than words.”, to abandon the history of reading for the sake of reading, the two-legged bookcase can not be transformed into knowledge to understand the world, the transformation of the world's metaphysical mechanistic reading, and call on the experts and scholars to further refine the classification, meaning and characteristics of“Reading”, scientific and effective distinction between“Literature”(writing) and“Contribution”(language) two major carrier of the application and promotion of literature. With a view to providing the readers with a personalized“Exclusive book list” that is in line with their subject background, reading needs and psychological characteristics, and guiding them in how to combine theory with practice and super-utilitarian reading, the reading of the whole people will be carried out to readers' safe, effective, sustained and healthy reading track.

Abstract: This article systematically examines the starting time of the compilation of the large-scale category book "Integration of Ancient and Modern Books" in the early Qing Dynasty, and distinguishes the common statement in general textbooks and reference books that the compilation began in the 40th year of the Kangxi reign (1701). It proposes historical evidence and argumentative materials that were compiled in the 39th year of the Kangxi reign (1700). Through reasons such as the lack of original historical materials, inconsistent compilation definitions, and the absence of original sources in the citations, etc, This article not only analyzes the root causes of the two starting times, but also proposes a basis that cannot be determined yet. It briefly introduces the value of the book in philology, providing a reference frame for our future in-depth research and application value of the book. It also provides scholars with strict textual research and comparison when citing books and periodicals compiled during the Ming and Qing dynasties. The popularization of knowledge in secondary literature needs to be carefully treated and the original text needs to be checked in a timely manner, Provided practical basis and classic cases.

Abstract: Reflection and experience are dual means of knowing truth. It has been more than 20 years for reading promotion in the new century. Whether it is traditional or new type of reading promotion, it needs to be constantly reflected and abandoned in the process of development, so that we can gain inspiration and guide practice. This paper uses the Frankfurt School's social and cultural critical theory as a cognitive tool, the false needs that readers have already generated, the pseudo-individuation of the case competition, the instrumental rationality and materialization consciousness that data commerce takes as the standard, and the anti-enlightenment of reading promotion from the perspective of the cultural industry. Focusing on the horizon, it reveals the problems existing in my country's reading promotion in the new era and the aspects worthy of the attention of readers and promoters.

Abstract:随着天文技术的发展,小型化天文卫星成为了天文领域的研究热点。作为天文卫星核心的氢原子钟,他的轻量化也势在必行。目前氢原子钟上使用的吸附泵为钛多孔材料,它的氢容量小,且体积大,激活温度高。无法满足氢原子钟小型化,轻量化的要求。本文研究了具有大储氢容量的 Zr-V-Fe-Cr 新型吸氢合金,并利用XRD、SEM、储氢性能测试平台等测试手段。结果表明:新型合金的 Zr-V-Fe-Cr 的吸氢容量高于多孔钛,且吸氢性能能够满足使用要求。为氢原子钟的氢源系统轻量化提供了新的选择,有望用在下一代轻量化氢原子钟中。

Abstract:通过野外观察、杂交指数(OCI)、花粉/胚珠比(P/O)、人工授粉、等方法,对长萼兰花蕉(Orchidantha chinensis T. L. Wu var. longisepala (D. Fang) T. L. Wu)种群的繁育系统进行了研究,并采用常规石蜡切片与扫描电子显微镜(SEM)观察了柱头与“V”形黏盘的结构与形态。结果表明:该种单花花期一般为18d,依其花部形态的变化可分为5个时期:(1)蕾期;(2)花萼未反转期;(3)花萼反转期;(4)唇瓣枯萎期;(5)花萼枯萎期。由于杂交指数(OCI)值为4,P/O值为253.89±21.09,结合人工异花授粉结实率分别为45%、75%,可以确定长萼兰花蕉属于异交,传粉过程需要传粉者;石蜡切片结果观察到长萼兰花蕉黏盘区与柱头可授区之间是光滑的表皮细胞,根据人工授粉实验与分泌物含糖量测定结果,表明长萼兰花蕉的“V”形黏盘不具有可授性,其作用可能是分泌粘液附着在传粉者背部使其便于携带花粉。长萼兰花蕉整个花期周围环境湿冷、多雨,且开花同步性较低,这些因素很可能造成了其有效传粉媒介的缺乏,影响了传粉成功,在有性繁殖受到限制时,通过根状茎进行的无性繁殖是其分布范围狭窄的主要原因。
