Summer and autumn, seedtime and harvest return in their stated order with a sublime precision . 夏天和秋天,播种和收获,都以其一成不变的顺序,十分精确地反复循环。
Cycles through the calculation until the result is accurate to within 0 . 00001 percent 反复循环进行计算,直到结果的精确度达到0 . 00001 % 。
Solarize for 3 - 5 hours every 10 - 15 days , for improving activeness and function of the product , and increasing frequency of repeating and cycling usage 每10 - 15天在烈日下曝晒3 - 5小时可增加产品活性,提高产品功效,加强反复循环使用频率。
The main equipment is the bio - safety cabinet ( type b2 is better , because it can avoid recycling of nucleic acid cabinet and cross contamination of specimens ) 仪器设备主要应有生物安全柜(最好为b2 ,可避免提取核酸在柜内反复循环,造成标本间交叉“污染” ,出现假阳性结果。
