1964年第九期《人民军医》曾介绍有关室内滞留喷洒杀虫药的方法,我们认为其计算步骤较为繁琐,不易为一般基层卫生人员所掌握,通过最近部队卫生防疫四项基本技术的训练,我们摸索出一个简便的计算公式。运用这一公式时,只需将墙面吸水量试验之面积,固定为划取1平方米、或划取2平方米、或划取4平方米,喷至湿而不流时,记下其实际喷水量(毫升),再用它除以一定的常数,便可求出每配一喷雾筒(容量6,000毫升)喷洒药液所需的原药量。现介绍供同志们参考:一、求每配一喷雾筒喷洒药液所需6%丙体666可湿性粉或50%223可湿性粉的数量(克)之计算式。设所需6%丙体666可湿性粉或50%223可湿性粉的克数为x,则:
In 1964, the Ninth People’s Military Medical Service introduced the method of indoor insecticide spraying. We believe that the calculation steps are more complicated and not easy for general grassroots health personnel to grasp. Through the training of the four basic technologies of recent military health and epidemic prevention, We worked out a simple formula. When using this formula, simply test the area of the wall water absorption, fixed to draw 1 square meter, or drawing 2 square meters, or drawing 4 square meters, spray wet and not flow, note it The actual amount of water spray (ml), and then use it divided by a certain constant, you can find each with a spray cartridge (capacity 6,000 ml) the required amount of drug spraying. Now for the comrades for reference: First, each spray with a spray liquid required 6% C 666 wettable powder or 50% 223 wettable powder number (g) of the formula. Suppose 6% C 666 wettable powder or 50% 223 wettable powder grams is x, then:
