本文以联合国教科文组织资助并由美国提供的ＡＤＣ（自动直径控制）技术的综合研究为依据，充分地论述了计算机自动控制、数据处理在晶体生长科研生产中的作用和意义。美国提供的ＡＤＣ技术的硬件部分主要有：主体单晶炉部分、直径功率的智能控制部分（包括电子秤、逆变电源、计算机等）、循环水温测控系统、生长气氛测控系统、晶体摄像系统等；软件部分主要有：ＡＤＣＳｏｆｔｗａｒｅ，ＡｐｐｌｉｃａｔｉｏｎＢｕｉｌｄｅｒＰｒｏｇｒａｍ，Ｗｉｎ３．１，Ｍｓｗｏｒｋｓ，Ｅｘｃｅｌ等。这一技术可确保生长Φ５０×２００ｍｍ的优质Ｎｄ∶ＹＡＧ晶体；通过我们的消化和改进预计可生长Φ６０×１８０ｍｍ的更大尺寸的晶体；同时，它还可应用于Ｓａｐｐｈｉｒｅ，Ｒｕｂｙ，Ｎｄ∶ＬＹＦ，ＧＧＧ等多种晶体的研究。无论其硬件、软件本身，还是其应用方面，对推动计算机技术应用于国内晶体研究领域的发展具有重要意义。该项技术的一个关键点在于它根据晶体生长的特性，实现了较为理想的直径和功率的智能控制，并通过计算机的强大功能实施了多路影响晶体生长因素的测控，实时地采集了对晶体特性进行研究具有重要意义的多组数据。另一关键点在于它通过在通用计算机上插接ＤＡＳ－ＨＲＥＳＢｏａｒｄ，把?
Based on the comprehensive research of ADC (Automatic Diameter Control) technology supported by UNESCO and provided by the United States, this paper fully expounds the function and significance of computer automatic control and data processing in the research and production of crystal growth. The hardware part of the ADC technology provided by the United States mainly includes the main crystal furnace part, the intelligent control part of the diameter power (including electronic scales, inverters, computers, etc.), the circulating water temperature measurement and control system, the growth atmosphere measurement and control system, the crystal imaging system, etc. ; Software parts are: ADCSoftware, ApplicationBuilderProgram, Win3.1, Msworks, Excel and so on. This technology ensures the growth of high-quality Nd: YAG crystals of Φ50 × 200mm; the larger size of Φ60 × 180mm is expected to grow through our digestion and improvement; and it is also used in Sapphire, Ruby, Nd: GGG and other kinds of crystal research. Regardless of its hardware, the software itself, or its application, it is of great significance to promote the development of computer technology applied in the field of domestic crystal research. A key point of this technology is that it realizes the ideal control of diameter and power according to the characteristics of crystal growth and realizes the measurement and control of multiple factors affecting crystal growth through the powerful functions of the computer. Features There are several groups of data that make a significant difference in research. Another key point is that it is through the universal computer plug DAS-HRESBoard, the?
