Problems in teaching of webpage making course The webpage making course is a very technical, applicable and practicable course, but now traditional class teaching pattern is used in many colleges, namely teachers instruct by the steps in the teaching material and then students practice them on the computer.
（3）Richness of network teaching resources: the network teaching platform not only includes courseware made by the teachers in our college, but also links fine course website of many key colleges, technology forum website, excellent enterprise website and material websites for students to learn.
Teachers propose course teaching reform scheme, make teaching plan, prepare teaching materials, perfect network teaching platform and organize students to register and select courses

It is well established that microstructured materials may be industrially prepared, e.g., by photolithography, but as the demand for smaller and smaller feature sizes always impose to lower the current state-of-the-art limits, further steps towards miniaturization have been raised in the last decade, focusing on different and more suitable strategies, which are based on both "top-down" and "bottom-up" approaches [1].
Since the remarkable number of related works published in journals of many different fields, e.g., chemistry, physics, materials science, and engineering, and the possibility of scale-up for industrial applications, a special emphasis will first be placed on the sophisticated procedures to arrive at continuous arrays of metallic or semiconducting objects from block copolymer thin films.

A Micro-Optical Transceiver for Interferometric Fiber Optic Gyroscope Kunbo Wang a, Yingjian Ma, Bo Zhang, Lishuang Feng School of Instrument Science and Opto-electronics Engineering, Beihang University, Beijing 100191, China a. wangkunbo_4@163.com.cn Key words: Transceiver, IFOG, Micro-Optical, thick film integrated technology Abstract: The application of integrated optical components into a single module provides a method of increasing the level of integration with the real potential of reducing unit cost and raising the reliability.
The key points are (1) using the small size optical elements: the beam splitter and the lens are 2mm×2mm×2mm; (2) the pick and placement of the small elements; (3) mounted the light source on the heat sink and proper choice of substrate materials provide the best means for thermal management and maintaining stability. 3 The integrated driving circuit of the optical source The stability of superluminescent diode has vital effect on the performance of fiber optic gyro [4].As for the IFOG system, the phase shift in an optical fiber of length L=NπD in a fiber coil of mean diameter D due to an input rotational rate Ω parallel to the fiber coil input axis as given by
