| 摘 要： | 利用PASCO公司生产的磁场传感器与运动传感器,设计了结合位移变化的磁场测定装置,该装置中添加了自行设计的反射板,使该装置可以在一定距离范围内连续地实时地测量某一区域内的磁场分布情况,并成功将该套装置应用到红豆生长的磁场生物效应实验中。利用该装置测量了红豆生长培养槽中的磁场分布情况,并研究了红豆处于该种特定磁场环境中,从发芽到生长7天的植株生长情况,研究结果表明磁场场强处于1.5~2.5 Gs(约3~5倍地磁场强度)时,其磁场对红豆生长起到了促进的作用。

Design and Application of Magnetic Field Measurement Experiment Apparatus Based on Relative Displacement Change |
| |
| Abstract: | A kind of Magnetic Field Measurement experiment apparatus based on relative displacement change was designed. PASCO’ s magnetic field sensor,PASCO’ s motion sensor and the reflecting plate of our own de-sign were used in this system. This experiment apparatus which could precisely measure the distribution of magnetic field were applied to the study on the biological effects of Magnetic Fields in red bean experiment. The study suggests that the specific magnetic field intensity(1. 5~2. 5 Gs,about 3~5 times the strength of the earth's magnetic field) may correspond to growth of Red bean. |
