怎样才能既时髦又舒适?Look cool and feel comfyHow to look cool and feel comfy?Today's fashions, such as slinky stilettos,skin-tighthipster jeans and cute hand-held purses, may look sharp but may not be all that great for your body .These tips will help you stay fashionable and comfortable:1. Wear high heels, but bring along a pair of flats to change into should your feet start screaming in pain.2. If shoes are uncomfortable when you stand, they're likely to feel even worse when you walk. The wrong shoes can affect the body's centre of gravity.3. While sitting for any length of time, take frequent standing breaks to alleviate atrophy of the hamstring muscles.4. If you like tight clothes, choose items that allow you to perform daily tasks with ease. These days, body-hugging clothes are mostly made ofstretchfabric - hooray!5. When carrying a bag or briefcase, switch sides frequently to avoid placing the bulk of weight on only one side of your body.6. Empty junk and other unnecessary items - old receipts, business cards, gum wrappers, etc - from your bag to make it lighter.7. Guys, if you're driving or sitting for long periods, remove your wallet or card holder from your back pocket. 时髦细高跟鞋、时尚紧身牛仔裤和可爱手提包等如今的时尚饰看起来很时髦,但对你的身体可不一定有好处。不过,下面的小提示可以让你既时髦又舒适。1. 穿高跟鞋时带一双平跟鞋,感到脚痛的时候换上。2. 如果穿鞋站着都不舒,那走起路来会更难受。穿不舒的鞋会影响身体的重心。3. 坐了一段时间之后,时不时的站起来活动一下,可以避免腿部肌肉萎缩。4. 如果你喜欢穿紧身的衣,那穿着它干活一定要舒。值得庆幸的是,如今的紧身衣大多是用弹性面料制成的。5. 拎手提包或公文包时,两边要频繁的换着拎,避免让身体的一侧负担过重。6. 把包里的旧收据、商务名片、口香糖包装纸等垃圾和其他一些不需要的东西清理掉,减轻包的重量。7. 如果你要长时间开车或要坐很久,记得把钱包和名片夹从裤子后面的口袋里拿出来。Vocabulary:skin-tight : 紧身的stretch : made of an elastic material(具有弹性的) /200803/32064

Huawei announced a major breakthrough in its research into Li-ion batteries, unveiling the world#39;s first long-lifespan graphene-assisted Li-ion battery able to withstand high temperatures.华为近日宣布了其在锂离子电池研究方面的一个重大突破--公布了全球首个能够耐高温、长寿命的石墨烯锂离子电池。The announcement was made by Watt Laboratory, an organization under Huawei#39;s Central Research Institute, at the 57th Battery Symposium held in Japan.华为中央研究院瓦特实验室是在日本举行的第57届电池讨论会上宣布的这一消息。Huawei#39;s research results show that new graphene-based heat-resistant technologies allow Li-ion batteries to remain functional in a 60°C environment, a temperature 10°C higher than the existing upper limit.华为的研究成果显示,新款石墨烯耐高温技术能够使锂离子电池在60℃的环境下正常运作,这比当前的上限要高出10℃。The lifespan of the graphene-assisted Li-ion batteries will also be twice as long as ordinary Li-ion batteries.此石墨烯锂离子电池的寿命还将是普通锂电池的两倍。Dr. Yangxing Li, Chief Scientist at Watt Laboratory, pointed out that three technologies contributed to the breakthrough in the graphene-assisted high-temperature Li-ion battery.瓦特实验室首席科学家李阳兴士指出,石墨烯高温锂离子电池的突破来自三个方面。First, a special additive in the electrolytes can remove trace water and prevent the electrolytes from evaporating in high temperatures. Second, modified large-crystal NMC materials are used for the cathode, improving the thermal stability of the cathode powder. Third, graphene allows for more efficient cooling of the Li-ion battery.首先,在电解液中加入特殊添加剂,除去痕量水,避免电解液的高温分解。第二,电池正极选用改性的大单晶三元材料,提高材料的热稳定性。第三,采用新型材料石墨烯,可实现锂离子电池与环境间的高效散热。Dr. Li said, ;We have performed charging and discharging tests in a high-temperature environment. The tests show that when working parameters are the same, the graphene-assisted high-temperature Li-ion battery is 5°C cooler than ordinary Li-ion batteries.;李阳兴士表示:“高温环境下的充放电测试表明,在同等工作参数下,该石墨烯基高温锂离子电池的温升比普通锂离子电池降低了5℃。”;Over 70% of the graphene battery#39;s capacity is left after it is recharged 2,000 times at a temperature of 60°C. Less than 13% of its capacity is lost after being kept in a 60°C environment for 200 days.;“在60°C高温循环2000次,其容量保持率仍超过70%;60℃高温存储200天,容量损失小于13%。” /201612/483259
