新规范(GBJ7—89)对老规范(TJ7—74)用作计算地基沉降的Es值有了较大的修改,GBJ7—89规范则要按实际应力范围取值,即以土的压缩系数α=(e1一e2)/(P2一P1)代替TJ7—74规范土的压缩系数a1-2=(e1一e2)/(2-1),本文分别对新老规范用作计算沉降的参数Es值分别作了分析比较。 相似文献

设备状态监测与故障诊断技术的基本原理与方法 总被引:1,自引:0,他引:1
1引言工业生产离不开机械设备,也离不开设备的管理维修。设备管理维修制度发展至今已具备三种类型。首先是事后维修(Break-downMaintenance),其次是以时间为基础的维修,通常称定期预防维修(Time-basedMaintenance),最后是以状态监测为基础的预测维修(Condition-basedMaintenance),或称为视情维修。预测维修制不同于过去的事后维修、定期维修制,它着眼于每台设备的具体技术状况,对设备运转状况密切追踪监测,仅在必要时才进行修理。规范化的诊断可以早期… 相似文献

After a previous study in which the considered oxidant was ozone (Part I), a laboratory investigation has been carried out to study the degradation of the herbicide isoproturon during its reaction with another oxidant, i.e. chlorine, in aqueous solution (Part II; this paper). The specific aim was to identify the by-products formed. The effects of pH and the presence of bromide ions were studied. Reactions have been carried out at room temperature, in phosphate buffered aqueous solutions, at four pHs (6, 7, 8 and 9). By-products identification was first performed using relatively high initial reagent concentrations which were analytically convenient ([isoproturon] = 40 mg/l, [HClO + ClO-] = 160 mg Cl/l, [Br-] = 80 mg/l). In follow-up studies, the by-products identified during this preliminary step were searched for when using concentration values closer to those actually encountered at real water treatment plants ([isoproturon] = 0.4 and 0.004 mg/l, [HClO + ClO-] = 1.6 mg Cl/l, [Br-] = 0.8 and 0.008 mg/l). Under all of the studied conditions, the results showed that isoproturon is completely degraded and that it decays much faster in the presence of bromide. The pH has a negligible influence when bromide ions are absent. On the contrary, if bromide ions are present, the isoproturon decay is slower at higher pH values. High-performance liquid chromatography-mass spectrometry (HPLC-MS) analyses have led to the identification of several by-products as a result of simultaneous oxidation and substitution reactions, both occurring on the aromatic ring of the herbicide. However, the more abundant by-products are those resulting from the oxidation of the isoproturon aromatic ring. As far as halogenated by-products are concerned, the higher the bromide ion concentration the higher the ratio of brominated to chlorinated by-products. On the basis of the analytical results, a pathway for isoproturon degradation under the studied conditions is proposed. 相似文献

Considerable effort has been invested in providing thermal comfort in tropical humid regions by increasing natural indoor air movement. This paper presents the result of investigation on the combined effect of balcony, opening design and internal division on the indoor airflows pattern of a living zone located on the second floor of a two storey building. The experiment was carried out by using the N3S software at the CERMA Laboratory, Ecole d’Architecture de Nantes, France.To observe the flows pattern inside buildings, we used the local average velocity coefficient as a function of the position in horizontal sections of 1.00 and 1.50 m in heights, for activity with sitting and standing position. The average velocity coefficient was calculated according to number of the measurement points in the living zone. The results identify opening and balcony designs to be helpful in increasing natural indoor air movement but not for internal division modification and they must be taken into consideration on designing dwelling in tropical humid region. 相似文献

The role of architectural education in facilitating the international flow of ideas and developing the local profession during the interwar period is relatively underexplored. In Australia, the Melbourne University Architectural Atelier (1919–1947) was instrumental in introducing foreign methodologies while promoting a locally inflected paradigm of modern architecture. Based initially on the Ecole des Beaux Arts, the atelier's emphasis on composition and form, rather than a single accepted architectural style, fostered a culture of experimentation among Australian architects. But its focus on scholarship instead of professional qualification led to its eventual demise, highlighting the complex relationship between global design culture and local architectural practice. 相似文献
