據(jù)專家表示,電磁爐的輻射頻率只相當(dāng)于手機(jī)的六十分之一,因此,電磁波并非“隱形殺手”,合理用之,還會對人的身體健康產(chǎn)生良好的作用。
電磁爐產(chǎn)生的“磁”絕大部分分布在鍋底,形成閉合磁場。
當(dāng)鍋具放在電磁爐上“工作”時(shí),電磁爐所產(chǎn)生的閉合磁場強(qiáng)度在電磁爐邊緣的最高強(qiáng)度為160毫高斯,而使用手機(jī)時(shí)所產(chǎn)生的信號磁場接近1600毫高斯,是電磁爐爐面邊緣磁場的10倍,由此可見,電磁爐所產(chǎn)生的磁場對人體影響遠(yuǎn)不如手機(jī)。
當(dāng)鍋具垂直離開電磁爐面板3-5cm時(shí),鍋具超出了閉合磁場范圍不會再生熱,同時(shí)電磁爐自動(dòng)停止工作;閉合磁場范圍之外的水平磁場非常微弱,大約占整個(gè)磁場能量的百分之零點(diǎn)零幾,甚至基本接近于地球的磁場。
當(dāng)鍋具的最小直徑小于8cm時(shí),電磁爐也不能工作。所以,根本不用擔(dān)心電磁爐的“磁”對人體的影響。
LONDON, July 8 (Xinhua) -- Zimbabwean tennis ace Cara Black and her doubles partner Liezel Huber on Saturday cruised into the Wimbledon final after dispatching 2007 French Open champions Alicia Molik and Mara Santangelo 6-4, 4-6, 6-1 in a thrilling three-set semi-final encounter that lasted two hours.
The match between the two pairs, who are not newcomers to each other after having met during this year's French Open semi-final, began fairly even as both teams tried to maintain serve. wow gold ,cheap wow gold , world of warcraft gold , sell wow gold .
It was, however, the African pairing of Black and Huber that got the early breakthrough when they won the break of serve deep in the middle of the set, and went on to claim the first set. sell wow gold , cheap wow gold , buy wow gold
Australian Molik tried to make good use of her vicious forehand, but the team wasted an easy opportunity for break point on the Black serve in the next game.
Huge serving by Molik then made little difference when she gifted the set to the African pair with a double fault. Santangeloand Molik did claw back in the second set which they won 6-4, and inadvertently threw the entire match up for grabs. cheap wow gold , cheap wow gold ,cheap wow gold ,cheap wow gold ,cheap wow gold .
