The Openness Degree Study of the Jiaoshiba Shale Gas, Sichuan Basin, China–Potential Factor Responsible for Reversed Isotope Series

Objective Reversed alkane δ;C and δ;H values in many prolific shale plays all over the world have aroused much attention in the study of the formation mechanism of reversed isotope series in alkanes in the past few years（Zou Caineng et al., 2016）. Although many researchers have put forward different hypotheses, the mechanism has not been well understood yet. The openness degree of oil and gas system

THE BRIEF INTRODUCTION OF CHANGCHUN JINGYUETAN OPEN REMOTE SENSING STUDY AND TEST SITE OF THE CHINESE ACADEMY OF SCIENCES

In 1979, the Changchun Jingyuetan Remote Sensing Study and Test Site (RSSTS)began its work, and it was formally established in 1985. The RSSTS is subordinated the Changchun Branch of Chinese Academy of Sciences and is supported by the Changchun Institute of Geography and Changchun Institute of Optics and Fine Machnics, Chinese Academy of Sciences. It is under the management of the Resource & Environment Bureau of Chinese Academy of Sciences and it is the study base of remote sensing basis and application tests in China. The RSSTS is situated in the Jingyuetan scenic spot of the suburbs of Changchun City, Jilin Province. It is located at 43°40′—43°50′N and 125°18′-125°18′E.

STUDY ON THE INTRAMOLECULAR CYCLIZATION THROUGH OPENING OF EPOXIDE I CYCLIZATION OF N-METHYL-N-BENZOYLMETHYLENE-β-PHENYL-α,β-EPOXYPROPIONAMIDE IN APROTIC SOLVENT

Intramolecular cyclization of A catalyzed by IDA in benzene or THF yields two γ-lactams through C-alkylation and one δ-and one 7-membered lactam by O-alkylation.

STUDY ON THE INTRAMOLECULAR CVCLIZATION THROUGH OPENING OF EPOXIDE II RING CLOSURE OF N-METHYL-N-BENZOYLMETHYLENE-β-PHENYL-α,β-EPOXYPROPIONAMIDE IN PROTIC SOLVENT

When the title compound was treated in protic solvent with alkali catalyses,γ-lacatam was almost the sole product.The ratio of ketone 1 to ketone 2 depended upon the reaction condition.
