国内外对影响离心式喷头特性参数的因素进行了不少研究试验工作。在这些研究试验工作中,所用喷头的结构、尺寸、形状、材料和加工情况以及药液的种类、性质都不完全一样,因而使其结果难于分析比较从而获得基本一致的规律。我院对于植保机械所用的离心式喷头进行了许多试验工作。本文则在此基础 At home and abroad have made a lot of research and experimental work on the factors affecting the characteristics of centrifugal nozzles. In these research experiments, the structure, size, shape, material and processing conditions of the used nozzles and the types and properties of liquid chemicals are not exactly the same, so that the results are difficult to analyze and compare so as to obtain a substantially consistent rule. Our hospital for the plant protection machinery used in centrifugal nozzle for a lot of testing work. This article is based here
