摘　　要：为降低钨系延期药的燃烧温度效应，开展了相关的试验研究。结果表明：在一定的温度范围内（-50～50℃），钨系延期药燃速与环境温度属非简单的线性关系；在钨系延期药中添加少量导热率低、具有良好隔热性能的硅藻土可以降低其燃烧温度效应，提高延期药的延期精度。In order to reduce the combustion temperature effects of tungten type delay composition, some experiments were put forward. The results show that the relation between the burning rate of tungten type delay composition and environment temperature is not simply linear in certain temperature range （-50～50℃）, the combustion temperature effects of the tungsten type delay composition can be reduced as adding a small amount of diatomite, which has low heat-conducting property and good thermal insulating performance, so the delay accuracy is improved.
