基于单片机的红外遥控解码电路的设计

通过水资源消耗强度及其变化指数，研究我国工业行业水资源消耗强度的演变趋势；采用对数均值迪氏指数分析方法（LMDI），将我国工业行业水资源消耗强度的变化分解为技术进步与产业结构变迁两个层面的作用。研究结果显示，1996－2006年我国工业水资源消耗强度总体上呈现不断下降的趋势；技术效应所导致的各部门用水效率提高是工业行业水资源消耗强度持续下降的最重要原因，结构效应所导致的用水密集部门的发展在一定程度上抑制了水资源消耗强度的下降。因此，加快技术升级和工业结构调整，有助于可持续利用水资源、建立节水型社会。

Design of Decoder of Infrared Remote Controller Based on Single Chip Microcomputer

The launching and receiving infrared remote control theory, given the remote control signal recognition and decoding. This design mainly through AT89C51 MCU decoding infrared remote control, the decoder hardware and appropriate sofeware are analysed and the program process diagrams are given.Adopting infrared remote control not only totally reliable and can effectively isolated electrical disturbance. So on the remote control system adopts single-chip microcomputer application design, remote control device will also have programming flexibility, control range, small volume, low power consumption, the function is strong, low cost, high reliability, characteristics, so the one-chip computer infrared remote control technology has broad prospects for development.
