| 摘 要： | 在无风有空气阻力的假定条件下，根据牛顿第二运动定律和水力学基本理论，推导出喷头射程的理论公式，并选取典型微喷头和喷头，在室内进行喷头射程影响因素的试验。试验结果表明：与国内外常用的经验公式相比，理论公式的计算值与实测值吻合较好，相对误差仅为5.05%。理论公式物理意义明确，计算精度高，适用于各种微喷头和喷头。

| Abstract: | Based on Newton movement law and hydraulics theories, a new theoretical formula of sprinkler range was deduced on the assumption of considering atmosphere resistance without wind. And the experiment for sprinkler range influence factors was conducted in the laboratory. The results show that the new formula was in good agreement with the data of different types of sprinklers comparing with other empirical formulas, and the relative error is only 5.05%. The theoretical formula has distinct physical meaning and high precision. It is applicable to all kinds of sprinklers and micro-sprinklers. |
