negative iron meaning in Chinese
阴离子
Examples
- It was showed that the more content and the finer granularity of rare - earth , the more number of negative irons
结果表明：稀土加入量越大，产生的空气负离子数目越多；稀土越细，产生的负离子数越多。 - The results showed that the traditional performance did not change by adding 2 - 3 % granularity of rare - eath and the readiation specification was in the safe scale by producing 800 - 1000 negative irons per cm3 , the diameter of anti - bacterial circle to golden staphylococcus is 18 millimeter , the diameter of anti - bacterial circle to colon bacil lus is 22 millimeter , the purifying formaldehyde ratio comes to 65 . 3 percent and the purifying ammonia - gas ratio comes to 52 . 11 percent
结果表明：加入重量比为2 ? 3的稀土细粉后，新型环保保健涂料的常规性能指标不变；其放射性亦在安全指标范围内，可产生800 - 1000个负离子/ cm ~ 3 ，对金黄色葡萄球菌的抑菌圈直径为18mm ，对大肠杆菌的抑菌圈直径为22mm ，具有较好的抑菌作用。
