研究毫米波细胞生物效应的新装置

A NEW SYSTEM FOR STUDYING BIOLOGICAL EFFECT OF MILLIMETER WAVE ON CELLS

介绍一种研究毫米波酵母细胞生物效应的新装置．它应用锁相技术使输出频率保持长期的高度的稳定度（±１０ｋＨｚ），并配有确定场强分布（衰减变化达９位）的矩形辐照室，实现了对单个细胞场强作用的精确控制，并自动跟踪观察和记录了它们的生长参数．

For studying the biological effect of millimeter wave on yeast cells a new system, of which the long-time output frequency stability (±10kHz) can be achieved by using tile phase locked technique, is introduced. In this system, a thermostat irradiation chamber is used which has a radiating slot (0.4mm×1.7 mm) with a definite field intensity distribution (the applied energy flux densities can be varied over nine decades). The field effect on single cells can be exactly controlled and the growth parameters of the scanned cells can be automatically observed and recorded.
