Water temperatures, sea levels, acidity and coral bleaching are rising so fast that hundreds of millions of people will be at risk within decades unless drastic action is taken promptly, scientists at the first global conference on oceans and Climate Change concluded. 首届全球海洋与气候变化大会的与会科学家总结道,水温、海平面高度、海洋酸性以及珊瑚白化现象正在迅速恶化,如果不立即采取有力行动,在几十年内,数亿人的生活将会受到威胁。
The perborate bleaches are not used commercially but are available for use by the consumers. Their bleaching action is similar to that of hydrogen peroxide. 过硼酸盐在工业生产中并不使用,但可供消费者使用,它们的漂白作用与过氧化氢相似。
The bleaching action of fluorides is slow in the alizarin dye procedure. 在茜素染料法中,氟化物的消色作用较慢。
Has no bleaching action and evaporates leaving no active residue. 无漂白作用并蒸发,无活性残余物。
The temperature is raised to that recommended for the particular fiber or blend and held for the time needed to complete the bleaching action; 将温度升高至适于该种纤维或混纺纤维的温度,并保温达到所需要的时间,漂白便完成了;
