浅谈我国房地产业发展经营模式--文化地产“湘水国际”强势搭载湘西第一古镇--黔阳古城（2）

近几年，伴随着房地产市场竞争的日趋激烈，很多房地产开发商开始引入全新的产品定位理念，采用多元化的竞争手段和全新的营销策略来获取竞争优势，文化地产也随之成为了广受关注的焦点。在文化地产项目中，地产是文化的载体，文化是地产的灵魂。可见，在文化地产这一复合概念中，地产依旧是主角，而文化则赋予了地产新的面貌。     

绿叶情

那一年夏天很热,晚上铺块凉席睡在地板上,汗仍是将人和席粘到一起。我这北方佬总想冲出去,到一个凉爽宜人的地方去渡夏,然而条件所限,只能是空想。在空想的逼迫下,竟然突出灵机:在楼后窗边的地上栽了一株小小的爬墙虎,它原来是我剪取的一个再不能小的小枝,插在花盆里的。在花盆里长了一年,枝条最多有30厘米长,没想到种到地上第一年它就从一楼爬到了二楼的墙上;第二年青枝绿叶爬满了二楼的墙面,爬进了我住的三楼的窗。头几天,窗上伸进来的盎盎生机让我非常喜悦,不忍心动它。不料没过几天,因雨水溅进屋要关窗却不能,原来是爬墙虎的枝条充溢于窗间,满满的绿叶遮住烈日的光,屋里一片绿荫、一片凉     

污水处理厂泵站与曝气系统的节能途径

阐述了污水处理厂泵站与曝气系统的节能原理，提出了对泵站与曝气系统各环节设备采取的节能措施对污水处理厂降低能耗具有现实价值。     

G6135受热负荷零件的温度场测试研究

上海柴油机股份有限公司生产的Ｇ６１３５柴油机在试验考核中,出现第五、六缸拉缸现象。为探究原因,测试人员自行设计,改装设备,运用硬度塞法和热电偶法分别对Ｇ６１３５柴油机活塞和缸套进行温度场测试,这进一步优化和改进零部件设计提供依据。     

楼顶绿化简法一则

首先根据自己的能力将楼顶划分几块地方,留出行走的地段。用木板或砖或泡沫塑料等将一块或几块地围起来,有条件者则将整个楼顶围起。木板或砖高度是30厘米,在围的框内铺一层塑料薄膜,以防漏水和将养分流失掉。然后在薄膜上放20厘米厚的杂草,杂草不好找时,可以放瓜果皮、瓜子壳、花生皮、丢弃的菜叶菜皮等。而后在其上放一层10厘米厚的土,或者炉灰,有     

An experimental study of the fracture properties of oil pipeline girth welds

The application of fracture mechanics to the "Fitness For Purpose" assessment of the fracture properties of pipeline girth welds is generally essential for the safe operation of oil pipeline systems. Based on the analysis of the fracture toughness requirements of the oil pipeline girth weld, a systematic study has been conducted on the fracture behavior of the API 5L X65 steel pipelin egirth weld made by two welding materials. The critical COD values of the pipe line girth weld under the different temperatures are tested. In the paper other influential factors on fracture behavior are also discussed, such as the welding materials, the welding positions (flat welding, vertical welding, overhead welding), the welded joint area (weld, heat-affected zone, fusion line and base metal) and the experiment temperature. The result shows that the welding material, the welded joint area and the experiment temperature have considerable influence on the fracture behavior of pipeline girth welds. It is also concluded that t he effect of the welding position is related to the welding process. The study provides a scientific basis for the welding of oil pipelines.
