With the aid of paraffin section and histochemical techniques, the formation, structure, development and polysaccharide's change of extrafloral nectaries in Cerasus were studied.

应用石蜡制片及组织化学技术对樱属植物花外蜜腺的形态、结构及发育过程中结构及多糖变化进行了较为系统的研究。

They can be classificated to two kinds. One kind is build by photomultiplier; another kind is build by MCP. The mechanism of delayed luminescence is discussed with subradiation. A photon count system is built. To proof the biophoton is a kind of ultra weak photon stream originate from exothermic reaction, and primarily discuss the relationship between the delayed luminescence and proteins activity, we chose microphyllous banyan leave , ficus elastica leave, gingkgo leave, Chinese fan palm leave, and cinnamomum camphora leave as biological samples. The ultra weak photon emission from normal biosamples, and proteins inactivated biosample were measured separately with photon count system. The results showed that the delayed luminescence of biosamples have

在研究过程中，作者从辐射陷获的角度讨论了延迟发光的产生机制，对生物光子的生物化学起源与相干场起源的统一性进行了探索；自行搭建了单光子探测系统；测量了小叶榕树、印度橡树，银杏树，蒲葵树香和樟树等多种植物叶片样品的延迟发光，获得了大量实验数据；为了证明生物光子是一种起源于放热化学反应能量释放的微弱光子流，并初步探讨生物蛋白活性与延迟发光衰减之间的关系，测量了正常生物样品、生物蛋白灭活样品的延迟发光，同时测量了多种不含蛋白质的无机化学体系作为比对，实验结果和实验数据的回归分析表明：弱光子发射来源于放热的化学反应，延迟发光的强度与衰减时间与生物蛋白活性密切相关。
