MM教育方式下常微分方程教学实验研究

研究高师MM教育方式下常微分方程教学实验方案的设计框架、实施措施和效果分析，初步摸索出一条MM方式下“问题探究型”(创设问题情景——巧用思想方法——探究‘自主发现’——推证新知结论——获得‘问题解决’——开发实际应用)的创新教学途径。     

验方治愈“浸淫疮”

一、浸淫疮历史渊源及解释 浸淫疮,是一种搔痒性湿疮。因该病发生常群集或密集成片,呈泛发性故称之为浸淫疮。引自《金匮要略》。《备急千金要方》卷二十二描述此病症候云：＂浅搔之曼延长不止,搔痒者,初如疥,搔之转生汁相连是也。＂其病因多因风、湿、热客于肌肤而成。症见初起形如粟米,瘙痒剧烈,搔破流黄水,浸淫成片,常伴见大便秘结、尿赤、舌淡红,苔黄腻或厚腻,脉弦数等。治宜祛风清热,利湿为主。内可服龙胆泻肝汤或升麻消毒饮或消风散。外用黄连粉或青黛散敷之。相当于急性泛发性湿疹。     

防治鸡瘟十法

母畜分娩后，排出胎衣的正常时间为：马1．5小时，牛12小时，羊2-4小时，猪1小时，超时不排即为胎衣不下。胎衣不下多见于牛，特别是乳牛，发病率高达15％-20％，并常继发子宫内膜炎，造成母畜不孕。     

An experimental method for measuring friction behaviors of linear rolling guides

Friction behaviors of linear rolling guides （LRGs） are determined by many factors and are crucial for precision positioning. It is difficult to create an expression to describe the friction behaviors exactly and completely. A new experimental method for measuring the friction behaviors of one LRG individually was developed, and linear motor direct drive technology is utilized in the experiment setup. The position signal is acquired by a grating, and the friction of the LRG is deduced by the product of the mass of the moving part and its acceleration. In the experiment, the LRG can move with the friction only, and the friction transition from normal rolling to pre- rolling stage was detected. The asperities＇ deformations were utilized to explain it. Hysteresis loops and internal loops were measured. The results indicate the non-local memory of the LRG, and the historical trajectory have an important impact on the friction behaviors of LRGs in the pre-rolling stage.
