天然石材的放射性现场检测在实际工作中具有重要的意义.但由于测量条件的限制,使现场检测的误差较大.文章从理论上探讨天然小板材的现场检测方法原理,选用H90-A能谱仪和ZDD3901石材检测仪,实测饱和条件下镭当量含量与伽马照射量率关系曲线.通过实测饱和度曲线,对不满足饱和条件的小板材进行饱和度修正,从而得到小板材的镭当量含量,根据GB6566-2001标准中外照射指标,进行石材类别的划分,可提高现场检测和判别石材类别的精度.通过实际运用得到较好的效果. 相似文献

British geology reveals many good looking rocks, both ‘soft’ and ‘hard’, some of which were once highly prized for their polished decorative uses. They were quarried, cut, shaped and finished in a locally‐based British decorative stone industry that flourished twice, first in the Middle Ages, based largely on Purbeck marble from Dorset and also alabaster from Derbyshire, and then again in the nineteenth century when diverse sources of coloured and textured stone were pursued to the far corners of the British Isles. Today only the finished products survive; the pillars, panels and pavement adorning some fine but dusty architecture, but the stones commonly languish unrecognized and unappreciated. This anonymity is quite out of line with the heritage status of their settings and it will take a bit more geological awareness to put that right. A recent project aimed at rediscovering just one regional category of British decorative stones, the Devonshire marbles, has revealed how diverse and extensively‐used the fuller range of British decorative stones actually is. Not only do they embellish buildings from the merely modest to some of our finest, they were latterly chosen, specified, designed and coordinated by some of our greatest architects. Much work needs to be done to recognize British decorative stones in architectural settings and to restore them to their proper place in our national heritage. It is hoped that this article will throw light on the task ahead. 相似文献

Cemeteries give evidence for a continuous change in sepulchral culture and provide insights into the application of characteristical rock materials used for tombstones during different times. Four selected cemeteries in Dresden (the Eliasfriedhof/Elias Cemetery, the Trinitatisfriedhof/Trinity Cemetery, the Johannisfriedhof/Johannis Cemetery, and the Städtischer Urnenhain/Municipal Urn Grove), which are of considerable cultural and historical importance, have been investigated within an ongoing mapping project. First results of this project focussing on the tombstone inventory of the mentioned graveyards and thus the use of building and decoration stones therein between 1680 and 1945 are presented in this paper. It can be demonstrated that the choice, variety, and application of rock material depends on the infrastructure and transport possibilities, but is also strongly influenced by sepulchral cultural trends and the prevailing zeitgeist. Until the middle of the 19th century, nearly solely Elbe sandstone (from the area of the Elbsandsteingebirge/Elbe sandstone mountains), that was transported on the Elbe river by ship, is found as rock material for tombstones in Dresden cemeteries. Rapid construction and development of the railway network starting around 1840 improved the availability, at first, of regional rock material (e.g., from the Lausitz/Lusatia) and, later on, from about 1880, of national and international—especially European—rock material (e.g., from Franken/Franconia, France, Scandinavia). Furthermore, the Friedhofsreformbewegung/cemetery reform movement at the beginning of the 20th century, with its significant effect on the selection of rock types used for tombstones, marks another historical breakthrough. 相似文献

微波等离子体炬质谱技术快速鉴别天然石材与人造石材 总被引：1，自引：1，他引：0
天然石材主要有大理石、花岗岩等;人造石材多以不饱和聚酯树脂为基料,添加适量的无机物粉料和添加剂固化制成。由于石材种类繁多,并且各种石材的岩体所含矿物成分也有差异,当前很少应用化学成分分析方法准确、快速鉴别天然和人造石材,仅有的红外光谱法由于对待测物纯度的要求较高而具局限性。本文基于微波等离子体炬源(MPT)同时具有热解吸与强电离能力,能在短时间内离子化待测物的特点,采用微波等离子体炬质谱(MPT-MS)技术,无需样品复杂预处理直接对天然与人造石材进行分析,获得正离子检测模式下在m/z 50~1000之间的石材的指纹谱图,并运用化学计量学的主成分分析(PCA)方法处理所获取的数据,实现了不同建筑石材的区分。结果表明,MPT-MS能够获得石材丰富的指纹谱图,结合PCA方法能够快速鉴别天然石材与人造石材,天然石材中解吸出的物质主要为CO2和H2O的团簇分子;而人造石材中解吸出的主要成分为有机物(人为添加的黏合剂等)。本研究采用的MPT-MS技术无需采用喷雾、激光、基质和加热等方法辅助,并且无需对石材进行任何复杂的处理即可进行质谱分析,从而获取石材表面及内部物质的质谱信息,为快速直接鉴定石材样品提供了一种新的质谱分析方法。 相似文献

Building stones have long been one of the most widely used construction materials in the world. Building stones used in historical monuments are deteriorated partly or completely depending on the environmental and atmospheric effects. In recent years, non-destructive test methods have been used to assess deterioration of building stones used in historical monuments. Gödene stone is one of the building stones being widely used in the historical buildings in the Konya region, Central Anatolia. The most deterioration effects are observed in the Ferit Pa?a Cistern among the historical structures built with Gödene stone in the region. The aim of this study is to assess the deteriorating effects in the street façade of the Ferit Pa?a Cistern via non-destructive testing methods (Schmidt hardness rebound value, P-wave velocity, humidity measurement and thermal imaging) and create maps of deteriorated features. Turkey’s historic places are integrated to Turkish culture, efforts are made to conserve heritage through rehabilitation. Therefore, this study will help developers and federal managers during the project planning stage by providing technical data. 相似文献
