现代科学技术的高速度发展,是建立在实验科学基础上的;科学实验的物质技术手段,随着生产和科学技术的发展而变得更加广泛、复杂。在本世纪二十年代以前,科学实验还基本上属于科学家的个体活动,它所需要的物质技术手段主要表现为:组装简单的实验装置及购置实验需要的仪器、仪表、材料、试剂等。由于当时生产还不发达,提供的产品数量少、技术简单,这些科研器材主要还是由科学家及其助手来购置,甚至亲自制作。到三十年代以后,科学实验活动已逐步从科学家单个的自由活动转变到了科学
The rapid development of modern science and technology is based on experimental science. The material and technological means of scientific experiments have become more extensive and complicated with the development of production and science and technology. Before the twenties of this century, the science experiment basically belonged to individual activities of scientists. The material and technological means it required mainly consisted of assembling simple experimental devices and the instruments, instruments, materials and reagents needed to purchase experiments. Due to the fact that the production was still underdeveloped, the number of products provided was small and the technology was simple, these scientific research equipment was mainly purchased or even personally produced by scientists and their assistants. By the 1930s, the activities of scientific experimentation had gradually shifted from a single free activity of scientists to science
