前言目前喷灌技术在我国已较为普遍应用和推广。并显示了它的优越性和强大生命力。随着农业生产的发展,对喷灌质量要求越来越高,这就要求喷灌机具在设计上给予一定保证。由于我国喷灌理论尚未全面建立起来,在喷头的设计上多参照国外特别是苏联的部分资料和水利学有关章节,但有些参数无法查到,或只能参考大至范围。在确 Preface At present, irrigation technology in China has been more widely used and promoted. And shows its superiority and strong vitality. With the development of agricultural production, the quality requirements of sprinkler irrigation is getting higher and higher, which requires the sprinkler irrigation equipment to give some assurance in design. Because of the theory of sprinkler irrigation in our country has not been fully established, some reference to foreign countries, especially the Soviet Union and the relevant sections of water conservancy are more referenced in the design of sprinklers. However, some parameters can not be found or can only be referenced to a large extent. Indeed
