看这本小说的时候,忽然不自觉打开音响,放入了一张肖邦的CD,选择了他的“离别曲”。这是一个关于离别的小说,三个六月,三次相距,三次分离。1989、1995、1999,三个六月,跨越了十年,就仿佛是一个苏格兰家庭史的缩影。美国全国图书奖评委会说它是一部“如交响乐般壮美的小说,它让我们浮想联翩,仿佛在浮想中永不知足……”而我却分明在其中看到了人性的坚持、彷徨、迷惘。有人说,爱是整个小说的灵魂,我却分明看到的是书中人物对它近乎尴尬的回避。人与人之间或许有坚冰,但融化它需要的却是我们的体温。作者说:这是一部讲述如何生活和生存的书。书中的人物过着上等人的生活,却依然不得不在欲望与情感中不断挣扎,忍受痛苦与分别。也许人性在命运面前确实没有高低贵贱,有的只是幸与不幸。幸运者到彼岸,不幸者则在对岸徘徊。 相似文献

Energy harvesting(EH)technology is developed with the purpose of harnessing ambient energy in different physical forms.Although the available ambient energy is usually tiny,not comparable to the centralized power generation,it brings out the convenience of onsite power generation by drawing energy from local sources,which meets the emerging pow?er demand of long-lasting,extensively-deployed,and maintenance-free Internet of Things(IoT).Kinetic energy harvesting(KEH)is one of the most promising EH solutions toward the realization of battery-free IoT.The KEH-based battery-free IoT can be extensively deployed in the smart home,smart building,and smart city scenarios,enabling perceptivity,intelli?gence,and connectivity in many infrastructures.This paper gives a brief introduction to the configurations and basic principles of practical KEH-IoT systems,including their mechani?cal,electrical,and computing parts.Although there are already a few commercial products in some specific application markets,the understanding and practice in the co-design and optimization of a single KEH-IoT device are far from mature,let alone the conceived multia?gent energy-autonomous intelligent systems.Future research and development of the KEHIoT system beckons for more exchange and collaboration among mechanical,electrical,and computer engineers toward general design guidelines to cope with these interdisciplinary en?gineering problems. 相似文献
