各种电子管、半导体三極管、二極管、整流器、电阻、人造晶体、絕緣材料等無綫电另件的發展和改进,不仅是一項科学技术任务,同时也是一項經济任务。世界科学水平是每天每日向前發展着的,为了爭取赶上世界科学先进水平,我們现在就需要預測几年內世界科学水平的进展,只有这样才可能在解决科学技术任 The development and improvement of radio parts such as various electronic tubes, semiconductor transistors, diodes, rectifiers, resistors, artificial crystals, and insulating materials are not only a scientific and technical task but also an economic task. The level of world science is developing daily every day. In order to strive to catch up with the world’s advanced scientific level, we now need to predict the progress of the world’s scientific level in a few years. Only in this way can science and technology be solved.
