A quantitative size exclusion chromatcgraphic method was developed for studying the complexation reaction between a biscrown ether and potassium picrate in tetrahyrofurane.

用定量的体积排除色谱方法。研究了双冠醚和苦味酸钾在四氢呋喃中的配合反应。

In order to obtain good ignition performance of the nitramine propellant, certain amount of potassium picrate with strong ignition ability was added. Three compositions with different formulations were designed, and their ignition performances were tested. The results show that the ignition delayed time of them were 1.79, 2.11 and 3.05ms respectively.

为使硝胺类输出药获得较好的点火性能，在配方中添加点火能力强的苦味酸钾制成混合药剂，设计了三种配方，并进行了点火性能试脸，得到点火延迟期分别为1.79， 2.11， 3.05ms。

This paper studied the application of potassium picrate in fuse head production,the theoretic analysis and experimentation proved that fuse head made of potassium picrate was much better than that made of KClO_3-C-DDNP.

通过理论分析对比和部分试验论证，从感度、安全性、燃烧精度、安定性、产品性能等方面，探讨研究了将苦味酸钾用于电引火元件的引火药剂可行性。
