德国最新一期《计量学》杂志刊载研究报告称,作为标准质量单位的国际千克原器因表面遭污染而略有增重。这意味着,你的体重比实际上轻,当然,轻的那点儿可以忽略不计。报告称,经过百余年岁月洗礼,这些铂铱合金圆柱体表面遭一定污染,增重数十微克。一微克为百万分之一克。来自碳基和汞污染报告作者之一、英国纽卡斯尔大学计量学家彼得·坎普森告诉记者,科学家早就意识到国际千克原器表面可能附着污染物,因此把它做成圆柱体,尽 According to a study published in the latest issue of the German metrology magazine, the international kilogram of the original standard unit of quality is slightly weighted by surface contamination. This means that your weight is actually lighter, and of course, the lighter one is negligible. The report said that after a hundred years of years of baptism, these platinum iridium cylindrical surface was polluted, weighing tens of micrograms. One microgram is one millionth of a gram. Peter Kempson, a metrologist at the University of Newcastle, England, one of the authors of carbon-based and mercury contamination reports, told reporters that scientists have long realized that there may be contaminants on international kilogram surfaces,
