ON A NEW OCHOTONID FROM NORTH SUIYUAN

In the course of the splendid summer trip which we enjoyed in the company of the American Central Asiatic Expedition in 1930, we, P. Teilhard de Chardin and myself, collected in the Late Tertiary Tung Gur basin (near Irdin Manha), some remains of Ochotonidae. Through the kindness of Drs. R. C.     

四川之脊椎動物化石

我國關於脊椎動物化石之研究,向以綏遠察哈爾及北方黃河流域為特著。南方各省,比較落後。但此等情形,不能遽斷南方各地之毫無希望有此等發見。最近廣西山洞動物群之採獲,與在湖北洋溪東湖系中鈍脚獸的尋得,都是顯明的告訴我們,只要我     

論錯誤

常言:「人非聖賢,孰能無過」,其實卽是聖賢,也常常閙過錯。過錯是無論什麽人都不能免的。尤其是研究科學的人,其所有著作中,差不多全免不了錯誤。所以有錯誤,並不是可恥的事,     

ON THE CENOZOIC GEOLOGY BETWEEN LOYANG AND SIAN

Bordered by the Chungtiaoshan (中條山) on the North and the Tsinling (秦嶺) on the South, the area between Loyang and Sian, where the Huangho River hits and follows the old Weiho valley has been known for a long time to be specially rich in Cenozoic formations of different ages. These deposits are

多通道大功率电法勘探仪集成试验

采用自主研发的多通道大功率电法勘探仪进行了深部矿勘探测试.首先在河北省张家口市张北县进行了仪器整体的调试和波形测试等试验,试验结果表明,在大偏移距情况下,尽管存在50 Hz电磁干扰,也能获得与发射波形相关的波形曲线,验证了仪器系统的正确性和稳定性.然后在内蒙古曹四夭钼矿区采集了4.8km的剖面数据,并进行了相应的数据处理工作.对所采集的数据进行了大地脉冲响应计算、峰值时刻提取和视电阻率计算,以及电阻率二维反演工作,反演的的电阻率断面结构与已知地质资料相吻合,验证了数据流程和处理方法的正确性.此次多通道大功率电法勘探仪的成功集成,为进一步大规模比对试验和装备整装勘探打下了基础.
