摘要：随着国家节能减排,墙改"禁实限粘"政策的落实,江汉油田房产处开始在改造老区和新建小区进行混凝土多孔砖的试用推广。受混凝土干缩性、密实度、吸水性等特性的影响,验收入住的住宅墙体及室内等处相继出现了大小不同程度的开裂。通过分析研究B型住宅的裂缝成因,提出了改变原料、改进设计、规范施工和加强监督防治措施。经过对已采取防裂措施建筑物的实地回访,砌体外墙开裂等现象得到了有效的控制。

摘要：去年4月3日,在首都北京举办的”92年中国消费者喜爱的50种保健品评选”中,虎晴牌延生护宝液力压群雄,在6000多种保健品的角逐中,跻身全国名优保健品七强之列。 沈阳飞龙医药保健品集团总裁姜伟对记者说,沈阳解放43年来,医药单项年产值最高在6000—7000万元徘徊,今天,飞龙集团的职工,已经满怀信心地驾着飞龙,突破了天文数字——2亿元大关。 诸多报家记者对飞龙集团的名优产品“延生护宝液”的显著疗效,泼墨几十万言,乃至数百万言,“延生护宝液”等保健品已名震遐迩。笔者不想在这方面赘笔,只侃侃姜伟其人其思想。

摘要：The stress strain curves of two CuZnAl shape memory alloys which have the martensitic transformation temperatures of 50 ℃ and -10 ℃ respectively, were measured by using electronic material tester after treated by different heat-treatment conditions. The results show that the area enclosed by hysteresis loop of the CuZnAl shape memory alloy in martensitic state is much larger than that of the alloy in austenitic state with super-elasticity at room temperature. Therefore, the former has better vibration attenuation effect. After being oil-quenched, water-quenched, and step-quenched, the CuZnAl alloy takes on more stable shape memory effect,better super-plasticity and superelasticity (pseudoelasticity). A CuZnAl shape memory alloy damper was designed, produced and installed to a 2-layer frame structure. In addition, the vibration experiments were made by dynamic data collecting analysis meter. The velocity of vibration attenuation of frame structure with CuZnAl shape memory alloy damper is much faster than that without it. And with the help of CuZnAl shape memory alloy damper, the attenuation period reduces to 1/10 of the original.

摘要：油田绿化工程已经成为广大职工群众关心的民生问题。搞好油田绿化工程造价精细化管理显得尤为重要。从油田目前的情况来看,在油田绿化工程造价上还存在一些具体的问题,一是设计方案缺乏优化。二是设计单位缺乏竞争。三是前期规划忽视配置规律。四是反季节施工导致工程造价上升。五是前期调查不足导致造价难以控制。要解决这些问题,必须做好五个方面的工作:1、推行限额设计和设计招标。2、规划方案遵循配置规律力求效果。3、公开评审设计方案以控制造价。4、测算反季节施工结算标准。5、强化实施阶段造价管理。
