1. It was clarified that torque induced in wood particles placed in a high-voltage electrostatic field was mainly caused by the polarization of OH radicals of wood.2. An electrostatic orientation system which has electrodes only at the reverse side of the forming belt was proposed. In this system, two mats were mated top to top to build up a special mat having better orientation towards both surfaces.3. A test plant of semi-industrial size was built up. The operational research verified that more even density of mat was achieved in this system than conventional systems, and small, thin particles would be suitable for the system.4. It was found that a certain thin sheet with anistropic dielectricity could increase the torque induced in wood particles when it was placed between electrodes and wood particles. This principle was applied to the above forming plant and remarkable improvement in particle orientation was achieved.5. Oriented boards produced by this new system had satisfactory properties for structural use in the oriented direction.

1.阐明了木材颗粒在高压静电场中产生的扭矩主要是由木材中的羟基自由基极化引起的。提出了一种只在成形带反面设置电极的静电定位系统。在这个系统中，两个垫子自上而下地配对，形成了一个对两个表面都有更好取向的特殊垫子。建成了半工业规模的试验装置。运行研究证明，该体系比常规体系获得了更均匀的板坯密度，且细小、细小的颗粒适合该体系。研究发现，将某一具有各向异性介电的薄片置于电极和木片之间时，可以增加木片产生的扭矩。将这一原理应用于上述成型车间，颗粒取向得到了明显改善。用这种新系统生产的定向板具有令人满意的结构性能，可用于定向方向。
