人类的环境,从星际尘埃到足下的土地,显而易见都由大量细小分散的物质所组成。 颗粒的固体堆集体通常称为粉末。粉末颗粒的技术研究和科研工作已逐渐被各个领域的科技工作者所重视和给以热情的关注。为了提高本市从事颗粒学科技工作者对专业知识的深入了解,上海颗粒学学会委托上海钢铁研究所于三、四月份组织 The human environment, from interstellar dust to the land beneath it, is obviously composed of a large number of finely dispersed materials. The solid particles of the particles are commonly referred to as powders. The technical research and scientific research of powder particles have gradually been taken seriously and given enthusiastic attention by the scientists and technicians in various fields. In order to enhance the city's granular knowledge of science and technology workers in-depth understanding of the Shanghai Institute of Particle Society commissioned by the Institute of Steel in March and April
