摘　　要：本文研究落塔试验技术中的3个重要问题。落舱的释放技术、落舱的回收和缓冲技术、试验的测量技术。讨论了有关的技术要求，给出了解决这些问题的若干技术途径及其特点，评价了不同技术途径的适用性。The drop tower is one of the effective tools for developing the micro-gravity research. In this paper one of the most important problems of the drop tower testing techniques the control of microgravity level-is investigated. Several technical ways to slove this problem are presented, and the relevant calculating formulas are given. The special requirements of the hydrodynamic tests in micro-gravity enivronment and their solutions are discussed. Some results of calcu1ation in the typical cse are given by this paper.
