<正>当低碳生活成为一种时尚,低能耗、低污染的"低碳旅游"概念也逐渐被不少景区和游客所推崇。低碳旅游虽然略显艰苦却点滴中透着环保,虽然"小众"却十分时尚,或许终有一天,它能够从时尚旅游概念变身为主流的旅游方式。燕子沟推荐理由:《2012》拯救全人类的诺亚方舟拍摄地,有良好的低碳形象。景区主要倡导低碳旅游。在以往的川西旅游地中,很少有人提到燕子沟,自《2012》放映后,燕子沟才慢慢被人所知悉并且变得更加有吸引力。冰川、雪峰、彩林、温泉这些川西该有的景色它都有,但最吸引人的,是长达30多公里的红石滩,红石的"身世"至今还是个谜。景区已尽量减少了观光车的使用,连扩建的步游道也是在以前山民采药时留下的道路上铺设的。景区内还停售一次性雨衣,提供免费雨具。 相似文献

Characteristics of heat transfer and flow resistance of the latticework (vortex) cooling channel with ribs truncated at their two ends were theoretically and experimentally studied compared with regular and smooth channels of the same configuration. The results showed: the heat transfer efficiency of the latticework channel with two slots was better than those of regular and smooth channels of the same configuration, its flow resistance situation in the slotted channel becomes quite complex; The flow resistances of 2 mm- and 4 mm-slotted channels were obviously lower than that of the regular channel, but they are still much higher than that of the smooth channel; Compared with the regular channel, the total heat transfer efficiencies of the slotted channels were pretty improved, among them the 4-mm slotted channel has the biggest enhancement. From the experimental results, it is obvious that the latticework channel with proper slots has a great prospect in the design of the inner cooling channels of turbine blades. 相似文献

To enhance the understanding of design characters, which have prominent influences during the fan blade out event, a simplified geometrical and dynamic analysis method was derived, and a typical 2-shaft high bypass ratio turbofan engine was selected and modeled. Based on analytical deriving and engineering experience learned from the real engine failure case, three determinative impact actions were recognized from the fan blade out process. The transient trajectories of these impact actions were researched in analytical method, and then thickness of acoustic lining, quantity of fan blades and threshold load of structural fuse were analyzed as key design characters. 36 serialized fan blade out transient dynamic simulations were conducted by using the 2-shaft high bypass ratio turbofan engine model within different combinations of the three key design factors. The results from geometrical and dynamic analysis matched mainly well with the results from simulations. Characteristic phenomenon in simulation can be explained theoretically. Five conclusions can be summarized from these results. (1) If thickness fan acoustic lining was thinner, the deviation between simplified analytical calculation and simulation were not outstanding to predict Blade-Casing the first impact time and angular position. (2) An appropriate thickness of acoustic lining could make a lower impact stress of fan casing at the first impact. (3) Different thickness of acoustic linings leaded to two impact modes for blade 2, which were tip impact and root impact. (4) Different impact conditions between blade 1 and blade 2 caused remarkable speed components distinction of blade 1, and leaded to a wide range of transient trajectory of blade 1 during FBO event. (5) Thicker acoustic lining in this research can usually find the porper threshold loads setting, which can give a satisfactory outbound vibration. Two details were raised for further research, which were impact behavior of composite material fan blade and honeycomb and influences of wider FBO threshold load ranges in design cases with thinner acoustic lining. 相似文献

议生态建筑 总被引:1,自引:0,他引:1
可持续发展的概念,现在得到国际社会普遍接受和认可的定义是,既满足当代人的需要,又不损害子孙后代满足其需求能力的发展.以往人们强调在经济建设的同时注意对环境的保护,这种保护的意义实质上是被动的,一旦遭到破坏,很难恢复,即使能够修复,所付出的代价远比它所获得的经济效益大几十倍甚至上百倍.经过几十年的实践,这种附属于经济建设的环境保护所取得的效果并不理想.现在人们已经普遍地感受到生态环境对经济发展及人类生存所带来的重大影响,因此从一般地考虑环境保护转移到把环境问题和发展问题结合起来,并把环境问题作为是否可持续发展的决定性要素之一.生态建筑,又称绿色建筑、环保建筑、节能建筑、可持续发展建筑.智能建筑也是生态的建筑. 相似文献
