查询词典 log

For example, 10 3 = 1,000; therefore, log 10 1,000 = 3. The kinds most often used are the common logarithm and the natural logarithm.

如，10 3=1，000；于是log 101，000=3。通常使用的有常用对数和自然对数

It was confirmed by Log-rank test that the cardiac allografts in group B and group C all survived longer than those in group A significantly (p.01). The survival time of the cardiac allografts in group C was also longer than those in groups B (p.05), which suggested that the recipients which pretreatment with SPC and CP was more efficient than that with CsA.(2)TGF-β1 is expressed as buffy granules in cardiac muscle and blood vessel dissepiment.

对数秩检验(log-rank test)证实，B组移植心脏的存活时间较A组明显延长，差异具有极显著性(P.01)；C组移植心脏的存活时间较A组也明显延长，差异极其显著(P.01)；将B、C两组移植心脏的存活时间进行比较时表明二者之间仍具有显著性差异(P.05)，说明SPC和CP联合预处理对移植心脏的存活时间的延长效果优于应用免疫抑制剂CsA组。2）TGF-β1阳性表现为心肌细胞浆及血管壁内出现棕黄色颗粒。
