职校课改中学生可持续发展的思考

中等职业教育学生的可持续发展问题,必须在职业教育的课程与教学方式的改革中引起关注。职业教育的传统课程模式,没有解决学生的可持续发展问题。基于工作过程的项目课程,不但能够帮助学生提高职业能力,也能够帮助学生提高关键能力。而真正的可持续发展还是要依靠完善的终身教育体系。

汉语声调不仅仅具有区别语义的作用,对于外国人来说,它也是学好标准汉语的基础,本文以在俄罗斯讲授汉语声调为例,讲解笔者是如何进行阳平、上声以及轻声的声调教学的.     

DULE TEMPLE

Dule Temple is located inside the west gate of the town of Jixian, Tianjin City. It was first built in the Tang Dynasty but the Front Gate and Mother Buddha Tower were rebuilt under the guidance of Han Kuangsi in 984 AD during the Song Dynasty. Dule Temple is known as one of the oldest extant wooden-structure buildings in China. According to Luo Zhewen, a renowned expert on ancient architecture, Dule Temple is a national treasure with unparalleled historical, artistic and scientific values.

Flow-through electroporation of mammalian cells in decoupled flow streams using microcapillaries

We report on reversible electroporation of cells in a flow-through microfluidic device, whereby the required electric field is delivered through a set of integrated microcapillaries between a centre stream of cells and side streams of liquid electrolytes. The electrolytes are applied with a sine wave voltage and cells flow by the microcapillary openings encounter a burst of ac field with a duration and strength determined by their average speed and spatial proximity to the microcapillary openings, respectively. Effectiveness of the approach is presented through numerical simulations and empirical results on electroporation efficiency and cell viability against various flow rates (exposure time to the field) as well as frequencies and root-mean-square (rms) intensities of the field. High frequencies (80–400 kHz) and high intensities (e.g., 1.6 kV/cm, rms) are identified with increased electroporation efficiency 61% and viability 86% on average. These results suggest that the device demonstrated here with a simple design and robust operation offers a viable platform for flow-through electroporation.
