Through analyzing the constant temperature field required for proper operation of the PCR chip, a new style active constant temperature control system was devised using a semiconductor cooling device as the temperature control component. 通过对PCR芯片工作所需的恒温场进行分析研究,使用半导体致冷片为温度控制部件,设计了一种新型的主动式恒温控制系统。
The calculated results agree well with the experimental data. The impurity level calculation formula which established based on electronegativity can be used to provide theoretical guidance in the search of proper impurity atoms for semiconductor doping. 计算结果与实验值符合得较好,这一基于电负性的杂质能级计算公式可以为寻找合适的杂质用于半导体掺杂提供理论上的指导。
