石英晶体元器件是信息产业发展不可缺少的重要元器件,由于它优良的频率稳定性和可靠性,以及应用领域的扩展,使这一重要的频率电子元器件得到了很大的发展。我国已成为压电晶体及其元器件的生产大国。压电晶体行业经过“八五”和“九五”的发展,目前全国有生产厂家200个左右,1999年底元器件产量超过10亿只,人造水晶材料1500吨左右,单就其产量来说,仅次于日本。仅就产量来说可谓大国,但产品档次,经济效益尚存在很大差距,主要表现在:
Quartz crystal components are an indispensable and important component in the development of the information industry. Due to its excellent frequency stability and reliability, as well as the expansion of applications, this important frequency electronic component has been greatly developed. China has become a major producer of piezoelectric crystals and their components. The piezoelectric crystal industry has developed through the “Eighth Five-Year Plan” and “Ninth Five-Year Plan”. At present, there are about 200 manufacturers in China. By the end of 1999, the output of components and components exceeded 1 billion, and the man-made crystal material was 1,500 tons. In terms of its output, Second only to Japan. Only in terms of output can be described as a big country, but there is still a big gap in product quality and economic efficiency, mainly reflected in:
