青海白丁香花挥发油化学成分的GC/MS分析

采用水蒸气蒸馏法提取了产自青海的白丁香花蕾的挥发油,应用GC/MS方法对其化学成分进行了分析,分离出47个色谱峰,鉴定了26个化合物,占总峰面积的88.7%,主要成分是丁香酚、丁香醇、石竹烯、苯乙醇等化合物。     

两次世界大战前后的亚欧关系探析

20世纪初叶“亚洲的觉醒”革命风暴作为现代亚洲民族解放运动的序曲 ,对亚欧之间殖民地 (附庸国 )与宗主国的依附关系形成强有力冲击。两次世界大战更是对亚欧关系的演变产生决定性影响。如果说第一次世界大战大大削弱了欧洲对其亚洲殖民地的控制 ,那么第二次世界大战则成为欧洲殖民体系崩溃、亚洲民族新生的历史催化剂 ,使亚欧之间的不平等关系发生了根本性改变。此外二战期间亚欧大陆两端人民在反法西斯斗争中同仇敌忾、互助合作 ,则成为该时期亚欧关系的主要内容。     

Operating systems

The objectives and stages of operating systems introduced in Part 1 are continued here. Four major components —process management, input-output (I/O) device management, memory management, file management and protection are discussed.     

Random vibration analysis of switching apparatus based on Monte Carlo method

The performance in vibration environment of switching apparatus containing mechanical contact is an important element when judging the apparatus’s reliability. A piecewise linear two-degrees-of-freedom mathematical model considering contact loss was built in this work, and the vibration performance of the model under random external Gaussian white noise excitation was investigated by using Monte Carlo simulation in Matlab/Simulink. Simulation showed that the spectral content and statistical characters of the contact force coincided strongly with reality. The random vibration character of the contact system was solved using time (numerical) domain simulation in this paper. Conclusions reached here are of great importance for reliability design of switching apparatus.     

水稻免耕栽培生理基础——Ⅱ.免耕水稻的光合特性

威优64、陆青早1号作为试验材料,免耕能提高功能叶的光合速率、生育前期功能叶的呼吸强度、绿叶面积、叶绿素和可溶性蛋白含量,并延缓它们在生育后期的下降速率,降低后期功能叶的呼吸速率。主分量分析说明,在研究光合作用时,光合强度、叶绿素、可溶性蛋白质、叶片含氮量,可以任意选择一个作为光合特性指际。粒/叶比说明,免耕对源的改善较对库的改善较好些。

当代新易家的理论建构——评张其成博士后的易学四书

当代新易家的理论建构为 :中华文化的主干既不是儒家 ,也不是道家 ,而是通贯儒道二家的“易道”。易符、易图、象数是“易道”的载体和表达形式。易学与中国传统生命科学紧密结合在一起。消解科学文化与人文文化的对立 ,消解中国文化与西方文化的冲突 ,促进人与自然的和谐、科学与人文的互补、中西文化的融合是当代新易家的追求目标     

Paired peer learning through engineering education outreach

ABSTRACT

Undergraduate education incorporating active learning and vicarious experience through education outreach presents a critical opportunity to influence future engineering teaching and practice capabilities. Engineering education outreach activities have been shown to have multiple benefits; increasing interest and engagement with science and engineering for school children, providing teachers with expert contributions to engineering subject knowledge, and developing professional generic skills for engineers such as communication and teamwork. This pilot intervention paired 10 pre-service teachers and 11 student engineers to enact engineering outreach in primary schools, reaching 269 children. A longitudinal mixed methods design was employed to measure change in attitudes and Education Outreach Self-Efficacy in student engineers; alongside attitudes, Teaching Engineering Self-Efficacy and Engineering Subject Knowledge Confidence in pre-service teachers. Highly significant improvements were noted in the pre-service teachers’ confidence and self-efficacy, while both the teachers and engineers qualitatively described benefits arising from the paired peer mentor model.
