保山气田新近系羊邑组二-三段沉积微相

保山盆地为滇西的一个具西断东超箕状断陷结构的新近系小型盆地。为搞清区内保山气田的沉积特征，指导该区油气勘探工作，结合沉积岩（物）与沉积环境之间的辩证关系，通过对沉积岩的岩性特征（颜色、岩石类型、岩石结构、黏土矿物、岩相组合）的分析研究，借助于沉积相在测井和地震剖面上的显著特征，研究并划分了保山气田新近系上新统羊邑组二-三段的沉积微相类型。结果表明，在该研究区主要发育了扇三角洲前缘亚相中的水下分流河道、分流河道间、前缘席状砂、河口坝等沉积微相类型，以及浅湖亚相中的浅湖泥和浅湖漫流席状砂沉积微相。剖析各类骨架微相的沉积特征后指出：水下分流河道、河口坝和前缘席状砂为该区最有利的储集砂体。

抗生素后效应对制定治疗方案的指导意义

抗生素后效应系指细菌与抗生素短暂接触后在抗生素被清除的情况下细菌生长仍受抑制的现象。本文对在临床应用中高度重视抗生素后效应的意义和方法作了阐述。     

En/Decoder for Spectral Phase-Coded OCDMA System Based on Amplitude Sampled FBG

A novel en/decoder for spectral phase-coded optical code-division multiple-access system based on amplitude sampled fiber Bragg grating (FBG) is proposed. Both equivalent chirp and equivalent phase shift are achieved by amplitude sampling. Compared with previous en/decoder based on step chirped FBG, it is easier to fabricate. The performance of the proposed en/decoder is verified by both numerical simulation and experimental demonstration.     

Kinetics study of Ti[O(CH2)4OCHCH2]4 initiated ring‐opening polymerization of ε‐caprolactone by differential scanning calorimetry

Chemical shrinkage was used for the in situ measurement of the progressing chemical stabilization reactions and the influence of ozone during the stabilization of polyacrylonitrile. A method for evaluating the activation energy through the sensitivity temperature is presented. The calculated results show that the activation energies were 161.57 kJ/mol in air and 181.23 kJ/mol in ozone-enriched air. Therefore, the chemical reactions were postponed during stabilization in ozone-enriched air. Ozone seemed to act in three ways: first, ozone promoted the formation of the serious skin–core structure. Second, ozone accelerated the chemical reactions and shortened the stabilization time at lower heating rates. Third, ozone postponed the chemical reactions. © 2008 Wiley Periodicals, Inc.
