数字表达的合理使用

今天谈一下数字在英文科技论文中的合理使用。同时与数字关联的往往是搭配的单复数和动词的协调使用。

10以下的阿拉伯数字，用来形容某个物体数量的时候，在一句话的非句首时，用对应的英文表示，如：one, two, three…, nine, ten。

范例1：

润色前：Its genome is a single chromosome of 2,242,062 base pairs containing 2,097 predicted protein-coding sequences,6ribosomal rRNA operons, and 63 tRNA genes.

润色后：Its genome is a single chromosome of 2,242,062 base pairs containing 2,097 predicted protein-coding sequences,sixribosomal rRNA operons, and 63 tRNA genes.

范例2：

润色前：A substitution model HKY85 with the estimated ratio of transition/transversion rate, gamma distributed rate heterogeneity of4categories and a proportion of invariable sites was used in the tree reconstruction.

润色后：A substitution model HKY85 with the estimated ratio of transition/transversion rate, gamma distributed rate heterogeneity offourcategories and a proportion of invariable sites was used in the tree reconstruction.

在句首，100以下的阿拉伯数字，用来形容某个物体数量的时候，用对应的英文表示。

范例3

润色前：13out of 324 sites (4.0%) in HA1 were found to be under differential selection at sites 24, 73, 99, 113, 121, 142, and 239 (p

润色后：Thirteenout of 324 sites (4.0%) in HA1 were found to be under differential selection at sites 24, 73, 99, 113, 121, 142, and 239 (p

范例4

润色前：12newly sequenced draft genomes and 15 publicly available complete genomes of different A. pleuropneumoniae serovars were annotated by using an automated bacterial annotation pipeline DIYA and custom Perl scripts.

润色后：Twelvenewly sequenced draft genomes and 15 publicly available complete genomes of different A. pleuropneumoniae serovars were annotated by using an automated bacterial annotation pipeline DIYA and custom Perl scripts.

用来形容物体个数数量的数字，大于1000的在数字中，每隔三位数加进一个逗号","，也就是千位分隔符，其目的是完了更加容易认读出数值。

范例5

润色前：To understand the phylogenetic relationships among the 12 serovars of A. pleuropneumoniae, we used two approaches based on noncore genic differences and the concatenated sequences of1287single-copy core genes among all serovar reference strains, respectively.

润色后：To understand the phylogenetic relationships among the 12 serovars of A. pleuropneumoniae, we used two approaches based on noncore genic differences and the concatenated sequences of1,287single-copy core genes among all serovar reference strains, respectively.

数字的使用不可小看哦，良好的写作习惯往往给我们加分！
