  drift theory
     Electron cyclotron resonance phenomenon has been studied with the help of drift theory modified. According to the analysis,we have found transverse relaxation time τ 1 or longitudinal relaxation time τ 2 to characterize relaxation processes respectively and have also given the physics significance about τ 1 or τ 2.

The article introdues an analytical model for determination of the two-phase mixture level in a PWR core during conditions of LOCA.The model isbased on the drift flux theory of two-phase flow and the assumption that theaccident progress was a quasistatic process.Results of the proving experiment coincide with those from the model.

According to the continental drift theory,the ancient ecology of the climateand geological vicissitude of the Cathaysian,Australian,South American,Afri-can,North American,Tropical Asian and Indian ancient lands or landmassesthroughout the Mesozoic Period are discussed.Subsequently,the characteristicsof the flowering floras of the ancient lands are analysed,the principal questionsunder discussion is concerning with the total amount,the composition and theantiquitic taxa,such as Magnoliales,Annonales,Ranunculales,Hamamelidales andthe orders of Amentiflorae,etc.And then,the discussed question falls on therelationship between the floras of the ancient lands and the Cathaysian flora.An interest and valuable existing State of affair has shown,that although theAustralian and the Antarctic landmasses was broke away from the mainland ofGongwana at the late Jurassic,but more than 40% of genera (998) are coexistingin Cathaysia and Australia; and in the proper order,a large amount of generaare found between the Cathaysia and India、Tropical Asia、north America、south America and Africa also.Thus it can be seen that the flowering plantswould be originate at the dawn of Triassic or Mesozoic,in other word,it wasoriginated before the breakdown of the unionized Pangaea,Such assessment isproved by the (?)ossils and the survived flowering plants.Following the driftinglandmasses,the flowering plants of all the continents are developed continuously along with the new environment.Lastly,a suggestion is given,that the Cathaysian flora is originated locally,since there are numerous primary taxa survived here which are not found fromother continents,and all the remaining landmasses either covered by the gra-cial or by the sea transgression,or by the droughty climate throughout theMesozoic Period,it is imposible to nurse the flowering plants,only the stabilized Cathaysia will become the cradle of the primary spermatophytes as well asof the flowering plants.

本文依据大陆漂移的理论,探讨了华夏、澳洲、南美、非洲、北美、热带亚洲及印度等古陆和陆块,在中生代各个时期的古气候和地质变迁的生态环境.同时,分别讨论了各个古陆和陆块的有花植物区系的特点,着重分析了它们的植物区系的总量,组成分子,具有哪些邃古性的成分,有多少木兰目、番荔支目、毛茛目、金缕梅目及葇荑花序类的代表.然后分别讨论了各个古陆或陆块与华夏植物区系的关系.以澳洲为例,它和南极古陆在晚侏罗纪即已脱离了贡瓦纳古陆的主体,竟拥有40%的有花植物属是和华夏植物区系共有的.依次的亲缘关系为印度、热带亚洲、北美、南美及非洲古陆,它们都与华夏植物区系具有很多共有的属.从而推论有花植物是在中生代初期的三迭纪或侏罗纪,就已经在统一的联合古陆(Pangaea)存在着.文章列举了化石及现代植物作为佐证.随着大陆飘移,统一发生的有花植物在各古陆继续发展下去.文章最后提到华夏古陆具有最多而且最古老的有花植物,它们只能是当地起源的.而其他各个古陆或陆块在整个中生代分别处于冰川、海侵及干旱的条件,很难成为原始有花植物的发源地,只有华夏古陆在古生代末期及整个中古代都处于较稳定的状态,在这里有可能是原始的种子植物及有花植物起源的摇篮.

The author, based on the theory of continental drift, analyzes the ecology of the climatic and geological vicissitude of each ancient continent, and come to the conclusion that the ancient plants of the citrus fruit trees group are reasonably supposed to have originated in these areas as Sichuan ,kang shen and South China ancient continent along with the India-China peninsula, then from these areas dispersed onto India, Africa...

This paper outlines the origin of citrus fruit trees group and their related plants. The author, based on the theory of continental drift, analyzes the ecology of the climatic and geological vicissitude of each ancient continent, and come to the conclusion that the ancient plants of the citrus fruit trees group are reasonably supposed to have originated in these areas as Sichuan ,kang shen and South China ancient continent along with the India-China peninsula, then from these areas dispersed onto India, Africa and Australia. According to morphological characters, the present-day distribution and ecology of the genus Fortunella, Poncirus and Citrus are considered to be originated primitively from China, while the genus Eremocitrus, Clymeniaand Microcitrus from Australia.

本文简要描述了柑桔类植物和其近缘植物;回顾了以往有关起源的论述.根据大陆漂移理论,分析各有关大陆的古生态气候和地史变迁.推测柑桔类植物祖先可能起源于四川、康滇和江南古陆以及印度支那半岛一带地域,然后传播至印度、非洲和澳洲.从柑桔类植物的形态特征、分布及生态状况等分析,认为金柑属、枳属和柑桔属起源于中国,而澳砂檬属、多蕊桔属和澳指蒙属则起源于澳州.
