1.确定了激光烧蚀微推进技术中烧蚀层的药剂配方，并探索实验了几种固化剂以改进聚合物GAP固化速率和固化效果，得出HDI为最佳试剂，固化速率大大改善，固化效果也显著提高。
2.对于GAP推进剂进行了不同程度碳掺杂，经过测试和对比，结果显示，不同百分比的碳掺杂对于靶带烧蚀推力的影响不大，有碳掺杂的靶带对应的微推力比无碳掺杂的靶带推力增加明显，碳掺杂在1.0%的效果最佳。最大推力可达到1786.36µN。lf0044

Title Doping effects of carbon on impulses of target ablated by laser
Abstract
Micro thruster is important for micro- and nanoelectronic satellite attitude control, track holding and maneuvering. The rapid development of micro and nano satellites need high level micro-propulsion system。In order to study laser ablation micro-propulsion technology, a series of works were carried out. The results were as follows:
1.To Determine the laser ablation micro-propulsion technology in the ablation layer of pharmaceutical formulations, several experiments were explored to improve the polymer curing agent curing rate and curing effect GAP. HDI was the best agent, which greatly improved the cure rate significantly.
2. For GAP propellant, varying degrees of carbon doping were tested and compared. The results showed that there is not any difference about thrust influence in varying degrees of carbon doped target. The carbon-doped target's thrust will increase obviously than that with no carbon-doped,in which the doping pencentage of 1.0% shows the best impulse.
