为科学奋斗终生的伽利略

1564年2月15日。伽利略出生在意大利的比萨城。他父亲是一位有才华的音乐家,但他从小就对数学和物理学感兴趣。在中学时期,伽利略就决心终生献身于科学事业,准备到大学里学习数学。但是,在那不讲科学的年代里,这一行意味着一辈子的贫困和默默无闻。因此,父亲反对他学习数学,准备叫他做一个服装商人。伽利略坚决不同意。父子两人经过妥协,1581年,伽利略进入比萨大学学医。     

在语文教育的路上,我们迷失了自己

韩军说,我们在语文教育的路上失落了太多的“根本”,于是他“呼唤中国语文教育返本归根”。在《中国教育报》组织的“在语文教育的路上我们失落了什么”的讨论中,有人认为,“我们失落了眼泪”;有人认为,我们失落了“语文基础知识”、“讲授式教学法”、“教学内容的科学性”等等。其实,细想来,最根本的是,在语文教育的路上,我们迷失了自己。一自清末“废科举,兴学校”以来,中国的教育一直在探索中艰难前进。就语文教育而言,教学内容从文言文转变为白话文;教学方法从注重评点串讲变为讲求师生互动;教育目的从以“传道”为主到以学习语言文字…

From the Didactic to the Dialectic—Intercultural Exchanges in Contemporary Counsellor Education

Within the context of the growing development of intercultural counsellor education, the question of how different cultures reconceptualize and transform Western counselling theories for their own context is an important one. In this intercultural exchange in education, concepts such as ‘globalization’, ‘indigenization’ and ‘universalization’ have an impact on the education process. This paper briefly explores these terms and movements and then highlights findings from a research project that took place with a group of counselling graduates in Hong Kong examining how they undertook the processes of reconceptualization and transformation. The dialogical process involved in that enabled participants and researcher to co-explore the process of knowledge development within the counselling education field. Implications for counsellor education are highlighted.

短跗星花金龟体表元素的X射线荧光光谱检测

采用Ｘ射线荧光光谱仪对体表为古铜色并有金属光泽的短跗星花金龟进行了体表（背、腹面）无损多元素定性检测。样品灰化后，对其灰又进行了多元素定性检测。结果发现，此种金龟子体表所呈现的金属光泽与虫体含有较多的Ｃｕ、Ｚｎ有关。     

Event triggering power sharing control for AC/DC microgrids based on P -F droop curve method

The power sharing of AC/DC micro-grids is researched in this paper. The proposed strategy mainly include two parts: the primary power event triggering control with secondary control and an adaptive quasi sliding mode voltage control in inner-loop. Firstly, a event triggering power sharing control (ETPSC) based on $P?F$ droop curve is developed to regulate the voltage and frequency of AC and voltage of DC with the aim of the proportional power sharing between AC and DC micro-grids. The triggered threshold of ETPSC can be chosen to decide the transmitted power between AC and DC micro-grids. When the difference power between AC and DC micro-grids is less than the triggered threshold of power flow, there is no power sharing between AC and DC micro-grids, which can less the number of switching the power flow direction and the transmitted line power loss. The ETPSC has a great robust for the disturbances of load and improve the stability of the system. An adaptive quasi-sliding-mode control,which is implemented easily and flexibly with small computational burden and only based on input/output (I/O) measurement data but not the model any more, is used to control voltage in inner-loop. The effectiveness of the proposed control schemes is demonstrated by some numerical simulations and experimental results.
