寻迹的英文

LP是许多英文单词的缩写。LinkinPark(林肯公园）的简称“粮票”的缩写卡片游戏<>中代表玩家的生命值.LP也是网络流行语之一，意思是老婆（LP为老婆汉语拼音首字母），常常用于开玩笑似的认亲。LP，(longplay),是立体声黑色赛璐璐质地的密纹唱片。为什么叫LP，主要是针对过去古老的粗纹短时间唱片而言。这是个简单解释。为什么在数码时代还要玩老东西？主要是因为那种空灵感和现场感是现在的CD无法取代的。如果你听过了LP，你将会对现在的CD的尖利粗糙的数码声不能忍受。而现代的CD为了尽量减弱数码声而开发了众多的电路和录音模式，但是仍然是不能和LP相匹敌。放LP的设备叫turntable，一般不带有功率放大器，只是前置级的输出，拾音模式大约有动磁，动圈和动铁的唱头，以动铁+线性寻迹的唱头唱臂为最优。

迹地英文：cut-over land解释：森林采伐、火烧后,五年内未更新的土地。解决方法：对迹地要因地制宜进行更新,以尽快恢复森林植被,防止因地表长期裸露造成水土流失而导致土地退化。

The design of simple intelligent tracing the car (tracing is to point to the small car in the white floor walk. Usually take to follow the black line is the method of infrared detection method), used for testing AT89S52 SCM control core. Use of three high sensitivity of infrared reflecting photoelectric sensor, the black road to track detection. Use the car in front of the infrared sensor test track on the road, road surface message to AT89S52 devices, AT89S52 devices according to the information reaction control motor rotation, so as to control the car on the way of running according to track. In addition, intelligent vehicle control system of the circuit module need different working voltage and current capacity each are not identical. Chip need to provide 5 V working voltage, and the voltage motor for 9 V, this design is used in 9 V power supply, through the LM7805 voltage stabilizer three will voltage transform for 5 V voltage supply circuit system. Therefore, the system is composed of electrcal sensor, microcontroller and drive units joint action by the three LM7805 convert module regulators required voltage, keep the small car in the predefined driving on the track. The whole system of the circuit structure is simple, reliable performance and is easy to realize high, are highly intelligent, and human nature, partly reflects the intelligence. The test results meet the requirements, the paper introduces the system hardware design methods and test results.The adopted technology of the car main sensor effective application and the use of AT89S52 chip. Have many functions can continue to expand, deserves further study and research.
