川西西康群的时代问题及其在区域构造上的特征

四川省西部高原地区广泛分布的西康羣,首先是由譚錫畴和李春昱在1930年对該区进行地貭調查时所命名的,并定其时代为侏罗紀。其后二十年来,进一步調查的人很少,但涉及西康羣时,不同的人則給予不同的推論。解放后,由于各方面工作的需要,一些单位在川西地区进行了不同精度的地貭調查,这才逐步地对西康羣有了进一步的认識。     

簡便的翻轉測船法

过去在測船維修中,往往要用不少人力来翻船,弄不好还会出事故。現在我站釆用一种簡便的翻船法。一个中等船(吨位5、6吨)用4、5个人就可以翻过来,船再大些也用不了很多人。其方法是: (一) 在船的一側用两根同样粗的木桩,放在舷上,交叉成“叉”字形,“叉”的高度視船的大小而定。两木桩碰头处要捆牢,两腿最好放在有船梁的地     

井噴及井噴預防

一、井喷发生的原因及现象储藏石油构造的地层,可能含有高压天然气、石油和水。当油田钻井穿过这些岩层的时候,天然气会很快的从孔底及四壁侵入钻孔而混入泥浆中。起初混入泥浆的天然气呈压缩状态的极小气泡,并随着泥浆循环而沿孔壁上升。由于上升程度的增加,泥浆柱对气泡的压力就逐渐降低,气泡因而渐渐扩大,泥浆的粘度也渐增,比重降低,体积增大,因此气泡开始从     

A STUDY ON THE ORTHOCLASE CRYSTALS AND TWINS OF CHIAOCHENG,SHANSI

The specimens studied were collected by Mr.C.T.Wang (王景尊)from Yuehfangkou (月房溝),a locality at about 1500 m.SW of Shangpei-chuan (上白泉) village,the latter at about 45 km west of Chiaocheng city.     

A CRYSTALLOGRAPHIC STUDY OF TOPAZ,BERYL AND SMOKY QUARTZ FROM FANCHIH DISTRICT,N.SHANSI

After our paper~2 on the Topaz from Mongolia,Shensi and KiangsuI took profit of a travelling in Shansi,in the early summer 1932,to visit thelocalities myself.The chief mineral producing locality is Houkoupei(后备     

ON SOME CRYSTALS OF TOPAZ FROM MONGOLIA AND NORTH AND CENTRAL CHINA

The crystallographical study of the newly found crystals of topaz was started by W. H. Wong and continued and completed by S. W. Wang under the supervision of the former. The angular measurements have been taken

小行星(116)Sirona的新軌道

小行星(116)Sirona在小行星星曆表中的位置是根據1929年卡斯德特(Kahrstedt)所算的軌道根数推算的,到1949年這顆星的O—C(觀测減計算)值便達到一度多,且很不均匀。因此有必要計算这顆星的攝動和軌道根數的改進。在蘇聯科學院理論天文研究所所編製的小行星星曆表中查得該小行星的卡斯德特氏     

克服在貫徹規范中的“歪風”

“水文測站規范”是学習苏联先進經驗和結合我國具体情况而制訂的,它的每一規定都有一定的理論根据和实踐經驗的印証,圍繞着提高资料精度,保証測驗質量;它是我們每个水文工作者的工作法規和指南,違反了它,就会在工作中犯錯誤,因此我們必須認真地学習和全面地执行。目前在大多数同志中都已樹立了規范就是法律的观点,貫徹規范已形成为一种自覺的經常的風气,这是值得發揚的好的一面,也是貫徹規范中的主流一面。但也有少数同志,认为規范“没有啥”     

CRYSTALS OF BERYL FROM TACHINGSHAN MOUNTAIN,SUIYUAN PROVINCE

OCCURRENCE. In 1918 Dr. W. H. Wong heard of the occurrence of beryl crystals in Tachingshan, north of Kueihua, from where the crystals were sent to Peiping, but he did not find the exact place of occurrence. Mr. H. T. Chang mentioned in his "Lapidarium Sinicum" that some of the Piyase in the Peiping market is not tourmaline but beryl and, this mineral was said to come from
