| 中文摘要: |
| 基于绿豆种子细胞的微观结构,建立了圆形、矩形的种子细胞膜理论物理模型,由薄膜受迫振动的理论计算得到了绿豆种子在超声辐射下的共振频率。在一定条件下,利用共振频率进行实验,对比单一频率、组合频率、复合频率分别辐射绿豆种子后的实验结果,分析不同方式的声场辐射下植物种子的生长发育状况。通过实验可以得到,超声复合频率对绿豆 |
| 英文摘要: |
| According to the microstructure diagram of the mung bean cell, the resonant frequency of the seed in radiation field were calculated based on the physics model of the circle and rectangular cell membrane. Under certain condition, the resonant frequency can be used in the experiment, compared the influence on the growth seeds through the experiment results in the single frequency, combined frequency and dual-frequency ultrasonic field. In this way ,we can analysis the development of plant seed under ultrasonic radiation.The results show that,the effect under the dual-frequency radiation is superior to the single frequency simulation. |
