About the name "spring", there must have been such a story:Before Book of Songs and Book of History, even before word formation, a lamb suddenly felt juicy when cropping grasses; a kid suddenly felt kite's soaring when flying it; a leg, pained from wind stroking all days long, suddenly felt stretched; thousands of snow-white hands suddenly felt spirituality of water when washing by brook, pond and river... All of them started running to tell each other surprisingly, when they decided to name the season by putting their mouths into a shape as if they were whistling and with a pleasant whispery voice, as "Spring".

关于春天的名字，必然曾经有这样的一段故事：在《诗经》之前，在《尚书》之前，在仓颉造字之前，一只小羊在啮草时猛然感到的多汁，一个小孩在放风筝时猛然感到的飞腾，一只患风痛的腿在猛然间感到的舒活，千千万万双素手，在溪畔，在塘畔，在江畔浣纱的手所猛然感到的水的血脉……当他们惊讶地奔走互告的时候，他们决定将嘴噘成吹口哨的形状，用一种愉快的耳语的声量来为这季节命名：&春&。

What Heppler didn't know is that out in thefree world,there is a larger urban global culturethat regards sneakers with the same highesteem—a streetwear-savvy population thatwill pay hundreds for the right shoe.Peoplewho post digital pics of their daily footwearchoices on message boards.Adult coupleswho save their best "deadstock" for their wedding days.Arty-sporty girlswho paint Nike swooshes on their bedroomwalls.Kids who camp outside urban boutiquesthe nights before limited-edition releases drop,so they can slap down $100-plus for a raritythey'll probably either put in storage or resell forthree times more on eBay.

不过那时候的海普勒并不知道，在外面自由的世界里正流行着一种范围更大的全球城市文化，对于球鞋，人们同样怀着崇高的敬意——他们对于街头服饰极其敏感，会为买到一双心仪的球鞋花上数百美元；他们会把自己每天所选择的各款球鞋拍成数码照片，贴到网站的留言板上；成年夫妻甚至会将他们最好的&多年珍藏&在结婚纪念日拿出来穿；拥有艺术细胞和运动细胞的女孩们会把耐克的&勾&形logo用油漆刷到卧室的墙上：在一些限量版球鞋发布的前一天晚上，孩子们为了排队，会在城里的专卖店门口宿营彻夜等候，直到啪地—声扔下100多美元拿走&稀世珍品&，然后要么把他们束之高阁，要么在eBay上以原价三倍再度转手。

Using the K20 eyepiece included as standard equipment, about 45x magnification, it's easy to see the Andromeda Galaxy and its smaller satellite galaxy M32. When compared to 60mm refractors, the Powerseeker 114 brings out much more detail in the Orion Nebula, reveals many more stars in Perseus' Double Cluster and even brings out a few individual stars in globular clusters like M13. Saturn looks quite small at 45x with the K20 eyepiece, but using my own 7.5mm eyepiece (120x) I can easily detect the shadow cast by the planet on the rings, and even glimpse the ring's Cassini Division. When the mirrors are properly lined up or "collimated," the images are reasonably sharp up to magnifications of 225x.

使用标准配件中的K20 目镜，可以得到45倍放大率，这时候很容易看到仙女座星系，还有较小的星系M32；和60毫米口径的折射望远镜相比，114 EQ可以看清更多猎户座星云的细节；瞄准英仙座双星团，看到的星体数量更多，显得更加壮丽；对于球状星团，比如M13，甚至可以显出其中少数独立的恒星；在K20 目镜下（放大45倍）的土星显得相当小，但换成我自己的7.5毫米焦距的目镜(得到120倍)，可以轻松的看到光环在土星上的投影，甚至可以瞥见土星光环内的卡西尼缝隙。

Conjugated polymers which are different from traditional semiconductor, have some unique properties. Most of them are quasi-one-dimensional systems with strong electron-phonon interaction. Their carriers are composite particles, which are different from simply electron and hole, characterized with the surrounding distortion of lattice configuration (polaron with spin 1/ 2 , bipolaron with spin 0 etc.). The transport of the carriers and the process that oppositely charged polarons combine to from exciton are believed to be of fundamental importance for electroluminescence properties.

共轭聚合物具有不同于传统半导体的特性，它们是强电-声相互作用的准一维体系，其载流子不再是简单的电子和空穴，而是伴随晶格畸变的具有内部结构的复合粒子(自旋1/2的极化子、自旋为0的双极化子等)，这些载流子的输运、以及正负极化子对复合成激子的过程在很大程度上决定着聚合物的电致发光性质。

In the United States, chronic alcoholism and hepatitis C are the most common ones.

在美国，慢性酒精中毒，肝炎是最常见的。
