Both rediometric dating and palaeomagnetic study show a very high magmatic activity during whole Cenozoic. The volcanic rocks in this region were formed no later than the Late Miocene. Considerable magmatic activity appeared during Pleistocene.It is also shown by the present study that the fundamental feature of changes in geomagnetic polarity here since Miocene is in agreement with the polarity time scale published recently and several polarity events of short term which had been in much controversy have been confirmed. The reversed polarity shown by the volcanic rock dated 0.58 ± 0.13 Ma has confirmed the occurrence of Emperor event. It has been also confirmed that there was a short term polarity event dated 0.78 ± 0.03 Ma below the B-M boundary and above Jaramillo subzones. Between Olduvai and Jaramillo subzones there was another normal polarity event which is likely to correspond to the Gilsa event.

雷琼地区火山岩的钾-氩同位素年龄测定和古地磁极性研究表明,新生代在该地区的岩浆活动一直很强烈。火山岩的生成年代不晚于中新世晚期,至更新世岩浆活动尤为强烈。 研究也表明中新世晚期以来这里的地球磁场极性变化规律与近期发表的地磁极性年表大体相符,并肯定了数个尚有争议的短期极性事件的存在。年代为0.58±0.13Ma的反极性火山岩的资料肯定了安比拉(Emperor)事件的存在。研究还证实了布容/松山极性时界线之下和哈拉米洛极性亚时之上有一短期的极性事件,其年代约为0.78±0.03Ma.在奥尔都维和哈拉米洛极性亚时之间存在有另一正极性事件,这可能相当于吉尔萨(Gilsa)事件。

Traditionally, paper was thought to be invented by Cai Lun (a. 61-121) of the Eastern Han Dynasty in 105.

The microscopic analysis done in 1964 showed that they were hemp fiber paper. Since then the Baqiao paper was accepted as an evidence which proves that paper was invented before the time of Cai Lun no later than 141 to 87 B. C. But after 1979 some people who persist...

Traditionally, paper was thought to be invented by Cai Lun (a. 61-121) of the Eastern Han Dynasty in 105. However, in 1957 some sheets of ancient paper made in the Western Han Dynasty had been unearthed at Baqiao near Xi'an of Shaanxi Province. The microscopic analysis done in 1964 showed that they were hemp fiber paper. Since then the Baqiao paper was accepted as an evidence which proves that paper was invented before the time of Cai Lun no later than 141 to 87 B. C. But after 1979 some people who persist in the theory that Cai Lun invented paper raised doubts as to the dating of the Baqiao paper and thought it was not paper but "a heap of waste hemp fibers". Thus a controversy about the Baqiao paper arose in China from that time on.

1957年在陕西西安附近的灞桥出土了某些西汉古纸,我们在1964年作了检验表明它是麻纸。自此,灞桥纸被承认为蔡伦前已发明了纸的证据。但1979年后,有人对灞桥纸的断代提出怀疑,并认为它不是纸,而是“一团废麻絮”。为此,我们在陕西对灞桥纸断代重新核实,并对纸样重作检验。我们认为,此古纸虽非科学发掘,而属基建出土,但它的断代是可以信赖的。近二十多年来,中国与日本的有关专家十次检验的结果,都证明灞桥纸是麻纸,而非“一团废麻絮”。此外,本文还列举了其余出土的西汉古纸,多次检验结果也证明它们都是麻纸。本文的结论是:灞桥纸是蔡伦前的西汉植物纤维纸。
