An investigation was conducted on the electromagnetic manipulation of particles.(1) Three-dimensional Distinct Element Method has been developed to clarify dynamics of particles. Not only the typical soft sphere model based on the Cundall model but also a hard-sphere model was established to reduce calculation time.(2) Numerical and experimental investigations have been carried out on the transport of particles in an electrostatic traveling field. This technology has been applied for linear transport, curved transport, transport in tube, and electrostatic separation of particle size utilizing the balance of the electrostatic and gravitational force.(3) Because the manipulation of single particle is of great importance in the areas of electronics and biology, an electrostatic manipulation system of single particle has been developed. It was possible to manipulate not only insulative but also conductive particles. Uneven and coaxial electrode systems were developed to release the attached particle independently of the position of the probe by utilizing ionic wind.(4) These technologies will be applied for the development of electrophotography machine, dust cleaner system for the lunar exploration, manipulation of lunar dust, and three-dimensional pattern formation of gel-beads for tissue engineering.

对粒子的电磁操纵进行了研究。(1)发展了三维离散元方法来阐明粒子的动力学。在Cundall模型的基础上,不仅建立了典型的软球模型,还建立了硬球模型以减少计算时间。(2)对静电行场中粒子的输运进行了数值和实验研究。该技术已应用于线性传输、曲线传输、管内传输以及利用静电力和重力的平衡对颗粒尺寸进行静电分离。（3）因为单个颗粒的操纵在电子领域非常重要和生物学方面，开发了单粒子静电操纵系统。不仅可以操纵绝缘颗粒，还可以操纵导电颗粒。开发了不均匀和同轴电极系统，利用离子风独立于探测器的位置释放附着的颗粒。（4）这些技术将应用于电子照相机、月球探测除尘系统、月球操纵的开发灰尘，以及用于组织工程的凝胶珠的三维图案形成。
