中文摘要：
针对星际转移发射机会搜索问题，结合等高线图法和主矢量原理，提出了一种多脉冲转移发射机会搜索方法．该方法首先通过绘制等高线图猜测出两脉冲转移的发射机会，然后基于主矢量原理，结合最优脉冲转移的必要条件和主矢量的变化历程，寻找潜在的最优三脉冲或多脉冲转移机会．以小天体探测为例的研究结果表明：与传统的两脉冲转移发射机会搜索方法相比，该方法引入主矢量，通过增加中间脉冲可以获得更多的潜在最优发射机会．
英文摘要：
To the search of launching opportunity for interplanetary mission, combining contour map method and prime vector theory, an approach to searching launch opportunity with multipleimpulse transfers is proposed. First, the launch opportunities with two-impulse transfers are guessed by plotting the contour map. Then, based on the prime vector theory, the potential launch opportunities with optimal three-impulse or multiple-impulse transfers are obtained via the necessary condition of optimal impulse transfers and time history of primer vector. Taking the asteroid exploration as an example, the research results show that this approach, compared with the conventional method with two-impulse transfers, obtains more potential launch opportunities using the prime vector and adding the middle impulse.
