改革开放前,中国的建筑设计机构全部为国有管理体制,单位级别分为甲、乙、丙级,其级别按单位高级职称、中级职称、初级职称的人数来进行评定。1994年《建设部、人事部关于建立注册建筑师制度及有关工作的通知》的下发,拉开了我国实行注册建筑师制度的大幕。随后,成立了全国注册建筑师管理委员会。 相似文献

Electron-optical study of the transformation behaviour in metalenriched chalcopyrite indicates that several metastable ordered variants occur in short term cooling experiments (Putnis and McConnell, 1976). The implications of this behaviour are discussed in relation to the theory of symmetry point ordering. This permits one to distinguish between three types of ordering transformation which differ markedly, both in the nature of the structural changes involved, and in their kinetics. A brief account of the theory of symmetry point ordering, based on a group-theoretical treatment by Landau and Lifshitz, is included. Analysis of the experimental results obtained on metal-enriched chalcopyrite indicate that metastable transformation behaviour in this system is associated with symmetry point ordering, and that partially ordered structures are produced. 相似文献

Smelt (Osmerus mordax) from six rivers along the coast of Massachusetts were examined for the microsporidianGlugea hertwigi and piscine erythrocytic necrosis (PEN), a viral blood disease. Of the 485 smelt sampled, 13.4% were affected byGlugea. Incidence ranged from 18.0% in the Town River to 0% in the Parker River. PEN was observed in all river systems. Incidence ranged from 97% in the Jones to 61% in the Parker River. Individual intensity of infection was low, with the majority of fish having less than 1% of their erythrocytes affected. The highest intensity for an individual specimen was 4.68%. 相似文献

Directional structures in the SE part of the Strzegom-Sobótka massif were studied with mesostructural and petrotectonic methods. These structures are most pronounced in quarries at Strzeblów and Chwaków. They were studied there byCloos 1922a, b and taken by him as reference structures for the Q, S and L joints system. New results from this study defined more precisely the types of structures and directions of related stresses. Statistical measurements of joints and veins performed in some quarries scattered over the massif area led to the conclusion that the pluton was subjected to a complex field of tectonic stresses.
Zusammenfassung Die Richtung der tektonischen Strukturen im Südostteil des Strzegom-Sobótka-Massives lassen sich in den Steinbrüchen von Strzeblów und Chwaków nach gefügekundlichen und petrographischen Methoden studieren. Hier hat auchHans Cloos 1922 seine Untersuchungen zum System der Q, S und L Klüfte durchgeführt. Neue Ergebnisse präzisieren diese Strukturtypen und ihre Beziehung zum tektonischen Stre\. Statistische Aufnahmen der Klüfte und Gänge über das gesamte Massiv führen zu dem Schlu\, da\ der Pluton während und nach seiner Intrusion komplexen Stre\feldern unterworfen war.
Résumé Dans la partie sud du massif granitique de Strzegom-Sobótka les structures directionnelles ont été étudiées par les méthodes mésostructurale et pétrographique. Ces structures sont le mieux exprimées dans les carrières de Strzeblów et de Chwalkow, où d'ailleurs H.Cloos (1922 a, b) les a prises comme références pour ses systèmes de joints O, S et L. Les résultats de la présente étude permettent d'en définir avec plus de précision les divers types ainsi que les directions des contraintes qui en furent responsables. Le relevé systématique des joints et des veines, étendu à un certain nombre de carrières à travers tout le massif permet de conclure que le pluton a été le siège de champs de contraintes complexes pendant et après son intrusion.

深部开采地表沉陷规律模拟研究 总被引:1,自引:0,他引:1
通过对煤矿深部开采沉陷的结构力学模型研究,提出了盆地水平煤层地表沉陷的理论预测模型,给出了整体和分步两种近似计算方法。在变动煤层开采深度和工作面长度的条件下,采用数值模拟方法对相关的数据进行了拟合计算对比,并基于现场沉陷观测数据对模型进行了验证。新模型方法结合力学模型计算得出开采沉陷预计参数,可以针对上覆岩层的力学参数对所得预测数据给出合理的力学解释,摆脱了经典预计模型概率积分法只依靠统计方法预测结果的缺陷,可为深部安全开采和地表沉陷的预测与控制,提供可靠的科学依据 相似文献

To increase the understanding of uranium transport in the environment and in the presence of steel corrosion products, the interaction of U(VI) with natural magnetite has been studied. Sorption studies have been carried out using X-ray photoelectron spectroscopy (XPS) and secondary ion mass spectrometry (SIMS). The XPS results clearly indicate the reduction of U(VI) to U(IV) on the surface of magnetite facilitated by electron transfer between the Fe and U, leading to a coupled oxidation of Fe(II) to Fe(III). 相似文献
