A virtual probe is a novel immaterial tip based on the near-field evanescent wave interference and small aperture diffraction, which can be used in near-field high-density optical data storage, nano-lithography, near-field optical imaging and spectral detection, near-field optical manipulation of nano-scale specimen, etc. In this paper, the formation mechanism of the virtual probe is analysed, the evanescent wave interference discussed theoretically, andthe sidelobe suppression by small aperture is simulated by the three-dimensional finite-difference time-domain method The simulation results of the optical distribution of the near-field virtual probe reveal that the transmission efficiencyof the virtual probe is 102-104 times higher than that of the nano-aperture metal-coated fibre probe widely used in near-field optical systems. The full width at half maximum of the peak, in other words, the size of virtual probe, is constant whatever the distance in a certain range so that the critical nano-separation control in the near-field system can be relaxed. We give an example of the application of the virtual probe in ultrahigh-density optical data storage.

为了研究小麦穗粒重与产量及其它相关性状之间的关系,本文以24个小麦品种(系)为材料,在怀远龙亢农场进行试验研究。通过对穗粒重与产量三要素及其它若干性状间的关系进行分析后,得出如下主要研究结果:1.安徽沿淮、淮北地区使用的大田小麦品种(系)中,穗粒重最重的在2.0克左右,大部分的小麦品种(系)的穗粒重在1.5-1.7克的范围内。根据穗粒重的系统聚类分析结果,初步提出了根据穗粒重来划分小麦品种类型的指
