The results indicate that the rare earth La changes the shape of doped tungsten powder from quasi-sphere to regular polyhedron and exists in the form of La_2O_3 both in powder and bars.

结果表明，稀土元素La的添加使掺杂钨粉的形貌由未添加La的准球形变为规则多面体；La在粉末和坯条中均以La2O3形式存在。

The burning rate adjusted by nanometer tungsten powder can reach up to millisecond level. The delay charge has been burnt reliably with the content of tungsten powder decreasing from 30% to 15%, the burning rate maximum has been appeared in fit gradation.

当钨粉含量由30%降至15%时延期药仍能可靠燃烧，并且适合的粒度级配使燃烧速度有局部极大值出现。
