2、static charge under low air pressure was presented in the paper. The necessity of ground simulation test study was expatiated. The ground simulation test system on electrostatic charge and protection of material under low air pressure was set up. The system can be used to simulate spacecraft materia
3、l electrostatic charge and research the laws. Furthermore， electric field initiative protection was presented， and three protection models were designed. One model was taken as example to be test. The result showed that： the protection technology can achieve good effect； the electrostatic potential of the material with protection is far less than that of the one without protection. Study on electrostatic charge and protection of material under low air pressure can support technology basic to the electrostatic protection system construction of spacecraft engineering. 2
