沙尘对不同居住年限居民肺功能的影响

目的掌握新疆建设兵团农十四师224团及皮山农场在不同时期进疆、不同居住年限的团场人员的肺功能状态及肺通气功能损害的类型,探讨年龄、不同接尘年龄、职业、心肺合并症等对肺功能的影响。方法采用日本捷斯特公司CHESTGRAPH HI-101型肺功能测定仪对519名兵团农十四师团场工作人员进行肺通气功能测定,结合既往病史、胸片、心电图、症状、体症等对所测定的结果比较分析。结果经Kruskal Wallis检验,519名兵团农十四师团场工作人员肺通气功能减退者107例,占23.21%。FVC、FEV1、FEV1.0%(FEV1/FVC%)、MMF、FEF25、FEF50、FEF75通气功能指标相互比较均有显著性差异(P小于0.001),尤以最大呼气中期流速(FEF)显著。结论兵团农十四师团场工作人员肺通气功能障碍以限制性为主,并与田间劳动、年龄增大、较低文化程度、患有肺气肿、肺心病、经常感冒、鼻炎、慢性肺炎密切相关。

bauma China 2012风向标

2012年11月30日,第六届中国国际工程机械、建材机械、工程车辆及设备博览会（bauma China 2012）（以下简称2012上海宝马展）在上海新国际博览中心完美收官。纵观2012上海宝马展,虽时处行业低潮,但展会各项数据却创历届之最：观众人数、展示面积和展商数量均再创新高。     

The Presence of the Weather

Modern architecture has dedicated much of its discourse to crystal-ball gazing – dwelling on the visionary and the speculative. Conversely, Kevin Nute , Professor of Architecture at the University of Oregon, puts the case for the present over the future and the past. To enhance experiences of the present, he describes how architects can harness the effects of changing temporal and weather conditions – sun and shadow, wind and rain. Design can heighten the sensory stimuli these conditions generate, keeping us ‘in the moment’ while still enjoying the comfort of being indoors.     

超耐候性氟树脂涂料

由氟代烯烃与乙烯基醚交替共聚反应并引入羟基、羧基、羟甲基、缩水甘油等官能团单体共聚合成的常温交联非结晶性聚合物组成的氟树脂涂料,具有超耐候性、耐化学性,且氧透过性低,对各种基材适应性及施工和再涂性均好,用途广泛,是未来21世纪普及应用的涂装新材料。     

大型滑移装载机——环境改变市场

<正>尽管读者对枯燥的统计数字感到厌烦,但我们仍要对北美市场的轮式滑移装载机和与其对应的小型履带式装载机的销售趋势进行一个小结。根据建设机械(Construction Equipment)最权威的数据,去年整个北美市场滑移装载机销售量为37000台,相比2012年的38000台略有下降,但相比2010年的26000台则好多了。     

Weather sensitivity in household appliance energy end-use

Data from a Residential Energy Study (RES) were used to examine the weather sensitivity of various household appliances located in households within the Sydney metropolitan area. Thermal environmental indices effective temperature (ET¹), standard effective temperature (SET¹) and simple air temperature degree–days were used to quantify the dependence of household appliance energy consumption on outdoor weather. Specific appliances included: room air-conditioners, room heaters, refrigerators, freezers and domestic hot-water systems, all of which exhibited some degree of weather sensitivity, particularly space heating and cooling devices. Probit regression techniques were used to predict the degree–day values at which households tend to switch on heating and cooling appliances. All appliances demonstrated weather sensitivity to varying degrees, and this was universally stronger during the cooling season (summer) than during the heating season (winter). The outdoor SET¹ version of the degree–day index demonstrated a stronger statistical association with space-cooling energy consumption than conventional air temperature degree–days. The mean daily temperature associated with minimum heating and cooling energy consumption for Sydney indicated that a temperature of 18 °C was the most appropriate base temperature for calculation of both heating and cooling degree–days.     

混凝土施工专项天气预报方法研究

为满足建筑行业混凝土施工作业对专项天气预报的需求,文章分析了《混凝土结构工程施工质量验收规范》中混凝土施工对气象条件的相关要求,根据多年气象资料总结出了日平均气温的预报方法。根据日平均气温的预报结果和混凝土控温措施之间的关系作出针对性专项预报,旨在为各气象服务部门开展混凝土施工专项天气预报提供一定的参考依据。
