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。

The generic distributions in both modern and fossil times were outlined, and their distribution center, place and time of origin and the way of dispersal were discussed. An attempt was made to discuss early differentiation, geographical radiation and morphological evolution of the family on the background of paleogeography and paleoclimatology, tracing back as far as the Late Cretaceous and Early Tertiary.

Based on 18 boxes of fossil specimens collected by the author from Xiaheyan, Zhongwei, Ningxia Hui Minority Autonomous Region and some other geological and palaeontological data from both Xiaheyan and the adjacent sections in the east sector of North Qilian Mountains, the present paper studies the botanical characteristics of Middel-Late Namurian Flora in Locality Xiaheyan and represents the primary reconstruction of the Middle-Late Namurian Flora in the Northeast Qilian Mountains, also tries to make available accounts for the correlation between the different Flora provinces, and discusses the origin time of Cathaysian Flora based on the succession and the transmissibility of the plants through the whole Namurian stage.
结合自从大学三年级一直到硕士研究生阶段笔者踏勘过的北祁连山东段地区十几条石炭系剖面，以及对相关文献的整理，笔者初步分析了北祁连山东段纳缪尔中晚期植物群的垂直演化分布情况，并完成了该期全球不同植物地理区系植物群植物学性质方面的简要比较。北祁连山东段地区纳缪尔早期与中晚期植物群的遗传性与继承性，加之华夏植物群的特征分子及一些东方型地方性分子在纳缪尔早期的出现，笔者认为这些无疑为晚古生代四大植物群之一的华夏植物群的起源完成于纳缪尔初期提供了有利证据。

One hundred and thirty four families, 578 genera and 1197 species are recorded in this area. According to the information of historical geology and natural conditions, the composition of seed plant flora and the areal-types of genera were analyzed. The results showed that its origin was rather ancient and its geographical compositions were complicated. There were many species of rare and endangered plants, e.g. Taxus chinensis var. mairei, Bretschneidera sinensis, Emmenopterys henryi, Fokienia hodginsii, Torreya grandis, Phoebe bournei, Ormosia henryi, and so on. Most of these plants had high value in economics and scientific research. According to statistics and analysis of genera in the present flora, 578 genera were divided into 14 areal-types. The ratio of tropical and temperate genera was respectively 48.6% and 49.2%, so its flora was characterized by transitional floristic elements, and in wide connection with the world.
该地区植物种类丰富，共有野生种子植物134科、578属、1197种；根据地史资料和自然条件，通过对种子植物种类的组成和分布区类型的分析，认为该区系起源古老，区系成分复杂；珍稀特有植物多，如南方红豆杉、钟萼木、香果树、福建柏、榧树、闽楠、花榈木等大量古老树种，并且绝大多数具有重要的经济价值和科研价值；区内578属可分为14个类型，热带和温带分布的属分别占48.6%和49.2%，具较明显的南北过渡的现象，与世界各地有广泛的联系。
