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)三维离散元法已发展到阐明颗粒动力学。在昆达尔模型的基础上建立了典型的软球模型，并在此基础上建立了硬球模型以减少计算时间。(2)对静电行波场中颗粒的输运进行了数值模拟和实验研究。该技术已应用于直线输送、曲线输送、管道输送以及利用静电力和重力的平衡进行颗粒尺寸的静电分离。(3)由于单粒子操纵在电子学和生物学领域具有重要意义，因此研制了一种静电单粒子操纵系统。不仅可以操纵绝缘粒子，还可以操纵导电粒子。开发了不均匀和同轴电极系统，以通过利用离子风独立于探针的位置释放附着的颗粒。(4)这些技术将应用于电子照相机、月球探测灰尘清洁系统、月尘处理和组织工程凝胶珠三维图案形成的开发。
