Pd/Ag/α-Al2o3 composite membranes were prepared by sequential electroless plating technique. The prepared membranes were characterized by X-ray diffraction （XRD）, scanning electron microscopy （SEM）, energy dispersive spectroscopy, and inductively coupled plasma atomic emission spectroscopy techniques （ICP-AES）. Effects of annealing time, Ag content, and air treatment on the hydrogen permeation flux and morphology of the alloys were investigated. The results of the investigation showed that the prepared type of tube had a good potential as substrate for membrane preparation. In addition, a uniform defect-free alloy was prepared by annealing at 550 ℃ in H2 atmosphere. The permeation results showed an increase in H2 permeation flux by increasing the Ag content and the annealing time. In addition, the air treatment of the prepared membranes at 400 ℃ for 1 h changed the morphology of the alloy and substantially enhanced the hydrogen flux.

1 地震危险性评定历史alvar.z在1970年依据历史强震资料试编了古巴的地震危险性图.进一步的编制工作包括补充新构造资料以及东南部板缘地震带的定量估算(Chuy和Rodriguez,1980;Chuy等,1983)。在地震建筑规范中,采用了许多最近的地震危险性图(NoRMA CUBANA,1985)。在古巴中部的核电站选址中,第一次采用了地震危险性的定量评定(alvar.z,1983)。采用Mc-Guire(1976)的概率算法,得出了古巴全境的定量评估(Rubio,1985)。alvar.z与Bune(1985a)采用一种特别算法评估了古巴东部的地震危险性(alvar.z和Bune,1985b)。还完成了圣地亚哥市的局部研究(Gonzalez和Kogan,1987),随后,以地震区划为目的,进行了较详细的全国范围研究(图2)(alvar.z等,1989a;alvar.z,待版)还完成了重要工业对象的非出版性研究。

慢性阻塞性肺疾病（简称慢阻肺）全球倡议（GoLD）于1998年由美国国立心肺和血液研究所（NHLBI）和世界卫生组织（WHo）共同成立，并于2001年颁布了第一版慢阻肺诊断、处理和预防全球策略（GoLD2001），其目标是根据已发表的最新研究结果制订慢阻肺的防治管理推荐策略。尽管不是临床指南，但该策略已成为各个国家或地区制定慢阻肺临床指南的重要参考依据。GoLD科学委员会每年对该策略进行年度更新，并分别于2006、2011年进行过两次重大修订。目前，GoLD2017版已经发布，并在定义，诊断评估和治疗等多方面进行了修订和更新。我们有幸邀请到GoLD理事会现任主席、西班牙巴塞罗那大学医院呼吸研究所的alvar.gusti教授撰写此文，就GoLD2017与中国呼吸界医师分享一些他个人的观点。本文由四川大学华西医院呼吸与危重症医学科安静医师翻译、文富强教授审校，并在译文后附有alvar.gusti教授的原文供大家参考与借鉴。

Sedimentary basins containing igneous intrusions within sedimentary reservoir units represent an important risk in petroleum exploration. The Upper Triassic to Lower Jurassic sediments at Wilhelm?ya(Svalbard) contains reservoir heterogeneity as a result of sill emplacement and represent a unique case study to better understand the effect of magmatic intrusions on the general burial diagenesis of siliciclastic sediments. Sills develop contact metamorphic aureoles by conduction as presented in many earlier studies. However, there is significant impact of localized hydrothermal circulation systems affecting reservoir sediments at considerable distance from the sill intrusions. Dolerite sill intrusions in the studied area are of limited vertical extent(～12 m thick), but created localized hydrothermal convection cells affecting sediments at considerable distance(more than five times the thickness of the sill)from the intrusions. We present evidence that the sedimentary sequence can be divided into two units:(1) the bulk poorly lithified sediment with a maximum burial temperature much lower than 60-70 ℃,and(2) thinner intervals outside the contact zone that have experienced hydrothermal temperatures(around 140 ℃). The main diagenetic alteration associated with normal burial diagenesis is minor mechanical plastic deformation of ductile grains such as mica. Mineral grain contacts show no evidence of pressure dissolution and the vitrinite reflectance suggests a maximum temperature of ～40 ℃. Contrary to this, part of the sediment, preferentially along calcite cemented flow baffles, show evidence of hydrothermal alteration. These hydrothermally altered sediment sections are characterized by recrystallized carbonate cemented intervals. Further, the hydrothermal solutions have resulted in localized sericitization(illitization) of feldspars, albitization of both K-feldspar and plagioclase and the formation of fibrous illite nucleated on kaolinite. These observations suggest hydro
