![IMG_20180215_113536.jpg](https://steemitimages.com/DQmc3tucx378S7ofoKfGRKQmufHUB58ubhUP4faqV4kGoFR/IMG_20180215_113536.jpg) 上个世纪的摩托车在乡村里是比较少有的,比如8-90年代的农村家庭有了摩托算是富裕人家,不说品质,单从价格来看与现代的相差不多,没有竞争就没有进步,那年代的摩托性能比较简单,如无现在的报警功能,没有后座的踏脚,而且耗油量也大,叫声噪杂,最让人难以忍受的是烟囱里喷出阵阵浓烟。 现在的摩托都已克服了这个问题,原来科学家在发动机上增加了一个小孔道让未烧尽的汽油烟返回到化油器进行二次燃烧,这样既充分利用了能源又保护了二氧化炭对环境空气的污染,科技就是在一举两得甚至更多的情况下诞生和发展,所以现在摩托车尾气几乎闻不到汽油烟味了。 前不久摩托的链条和压板齿轮已磨损,从而影响车子的运行动力,必须换新,修车师傅问我要65元的还是85元一套(一付链子和大小两个传动压板轮)的,我想贵的一定是质量更硬更耐用,便选择了后者。后来师傅告诉我,它的压板齿轮凹槽里被打深了一道痕,这道痕并不是与链条刚好吻合,也就是当链条把泥土带到齿轮上时就被这道沟痕吸纳然后挤出沟外,尽管再多的泥沙粘上去也不会损害齿轮,不认真还真看不出来,这样一个小小的改进既减少了金属用材又增加了链子与齿轮的使用寿命,这的确是一个更高明的法子。 ![IMG_20180206_144037.jpg](https://steemitimages.com/DQmNjCNGh8jVTkQaXgENVp1puHo4FM7ZD9rkVyDHHHWPfYM/IMG_20180206_144037.jpg) 尽管科技在不断变化,按现在价格一辆普通摩托是4000多元,按其币值来算可能不到当年一半的价钱,但是便宜归便宜,科技还是不断地人性化发展,科技以人为本,创新就是现代生产发展的永恒的主题。

科技驱动技术进步,技术进步提高劳动生产率,劳动生产率提高便会降低产品的市场价格。

这个方法确实高明,就是不知道运用了什么原理。
