China's July exports were hurt by a big drop in business with
the European Union—but some of the blame also goes to a long-term
deterioration in China's export competitiveness.
《中英對照讀新聞》Lithium-Ion Battery Life Could Reach 20 Years 壽命可達20年的鋰電池
◎陳成良
Japanese research and development firm Eamex claims to have found a new way to increase the typical average life of a high-capacity lithium-ion battery. Eamex’s new technology will allow the demanding batteries to sustain over 10,000 recharges over the course of 20 year.
日本研發公司Eamex聲稱已發現能增加高容量鋰離子電池一般平均壽命的新方法。Eamex的新科技將可讓這種高需求的電池持續工作20年，並重複充電1萬次以上。
This rather dramatic increase in performance is made possible by new techniques such as a stabilization process of the battery’s electrodes, which in-turn puts less stress on the battery’s tin.
一些新技術使得大幅提升電池效能得以實現，像是透過一種穩定電池電極的過程，能讓電池的錫承受較小壓力。
This maintains the bonding of particles for a longer period of time and reduces the overall deterioration process. The result is a battery that lasts up to 10 times as long as most current batteries.
這可能讓粒子的結合維持較久時間，並減少總體的老化過程，其結果是，電池使用壽命是大多數現有電池的10倍。
Lithium-ion batteries are broadly popular within various consumer electronics. They tend to hold their charge when not in use, and have a high energy-to-weight ratio. Current lithium-ion batteries can hold their charge for up to 1,000 charge cycles.
鋰離子電池普遍使用在各種消費性電子產品上，它們在非使用狀態易於保持電量，且能量—重量比例高。目前的鋰電池可以充電達1000次仍保有電量。

Electric car goes the distance (HIROYUKI KOBAYASHI/ THE ASAHI SHIMBUN)
Engineer Tadashi Tateuchi holds up a sign displaying the distance he traveled in an electric vehicle--555.6 kilometers--during a 13-hour-plus journey Tuesday from Tokyo to Osaka. It is the longest distance covered by an electric vehicle on a single charge, according to Tateuchi, who heads the citizens group Japan Electric Vehicle Club. He plans to register the feat with the Guinness Book of Records. The two-seater minicar, powered by about 8,000 cylindrical lithium ion batteries, weighs about 1,060 kilograms.(IHT/Asahi: November 18,2009)
Carry through a course of action to completion. For example, He said he's willing to go the distance with this project. This expression originated in boxing, where it means "to last for all the rounds that have been scheduled." In baseball the same term means "to pitch an entire game." For a synonym, see all the way, def. 1.
常有先見之明的美國科學家麥克林托克（Barbara McClintock，1983年諾貝爾生醫獎得主）在1930年代就以人為的方式打斷染色體，她發現染色體的斷裂端會彼此連接在一起，形成異常的染色 體，但是完整的染色體不會有這種現象。她推測染色體的末端具有某種特殊的結構，能夠保護染色體，讓染色體不會彼此連接。現代遺傳學奠基者之一的繆勒 （Hermann J. Muller，1946年諾貝爾生醫獎得主），在同年代也有類似的發現，他將染色體末端的特殊結構命名為端粒（telomere）。隨著分子生物學家的眼光逐漸從原核生物系統擴大到真核生物系統，端粒也越來越受到重視。
■端粒的研究引發治癒癌症與延長壽命的想像，
但是其實相關的研究才剛起步。
大膽的實驗，意外的發現
端粒是真核生物才有的結構，每個細胞中數量有限（
A telomere is a region of repetitive DNA sequences at the end of a chromosome, which protects the end of the chromosome from deterioration or from fusion with neighboring chromosomes. Its name is derived from the Greek nouns telos (τέλος) "end" and merοs (μέρος, root: μερ-) "part". The telomere regions deter the degradation of genes near the ends of chromosomes by allowing for the shortening of chromosome ends, which necessarily occurs during chromosome replication.[1] Over time, due to each cell division, the telomere ends do become shorter.[2]
During cell division, enzymes that duplicate DNA cannot continue their duplication all the way to the end of chromosomes. If cells divided without telomeres, they would lose the ends of their chromosomes, and the necessary information they contain. The telomeres are disposable buffers blocking the ends of the chromosomes, are consumed during cell division, and are replenished by an enzyme, telomerase reverse transcriptase.
