But there are few researches on robot ’ s olfaction , although the olfaction robots can complete lots of serious dangerous work instead of human , for example , finding the leakage of drugs , landmines , leakages of pipe and so on . 但是对机器人的嗅觉的研究和应用则相对较少。而具有嗅觉功能的机器人可以替人类完成很多高危险的工作,如进入毒气场搜寻毒气源,寻找地雷,查找管道的泄漏点等。
After introducing the development of robots olfaction and smelling robots , the article concludes the principle and frame of smelling robots based on the analysis of the principle of biology and searching odor source algorithms , then expatiates on the signal processing algorithms , pattern recognition technology , and presents many searching algorithms 本文介绍了机器人嗅觉系统以及嗅觉机器人的发展现状,通过对生物的嗅觉机理以及对生物搜寻气源方式的研究,总结归纳了嗅觉机器人的工作原理和结构。介绍了传感器信号的预处理算法和模式识别技术和几种常用气源搜寻策略。
Syndrome differentiation is a process where doctors analyze and summarize the relevant information gathered from the four diagnostic methods ( inspection , auscultation and olfaction , interrogation , and pulse feeling and palpation ) , including all symptoms and signs , make judgment of the properties of the syndromes based on this information , and probe into the essence of the disease 辨证就是将四诊（望、闻、问、切）所收集的有关疾病资料，包括各种症状、体征等，加以分析、综合，判断为某种性质的“证候” ，以探求疾病的本质。
