技术进步,主要表现在技术上更新产品品种、掌握一切新产品以满足日益增长的社会需要和生产出更完善更先进的高质量产品等方面。一种新产品,尤其是新的机器、设备,仪器的问世,会引起新的生产需求,并成为各门科学技术发明创造的源泉。产品的结构和特性是在不断更新着的。对于决定国民经济一切部门技术水平的机器制造工业来说,这个过程尤为明显。在1967年改革批发价格和1972年修订价格期间,机器制造和金属加工业的产品品种更新了50％以上,其中机床制造业的产品更新了三分之二。苏联的机器制造业每年要掌握3,000种新的机器和仪器。如今,更新产品品种的速度还在日益加
Technological advances are mainly manifested in the technical updating of product varieties, mastering all new products to meet the growing social needs and producing better and more advanced high-quality products. The advent of a new product, especially new machinery, equipment, and instruments, will create new production needs and become a source of inventions and inventions for all science and technology. The structure and characteristics of the product is constantly updated. This process is particularly evident for the machine-building industry, which determines the skill level of all sectors of the national economy. During the wholesale price reform in 1967 and the revised price in 1972, the product range of the machine building and metalworking industries was updated by more than 50%, of which machine tool manufacturing products were updated by two thirds. The Soviet machine-building industry has 3,000 new machines and instruments each year. Today, the speed of updating product variety is still increasing
