1.关于用现在时,还是一般过去时的问题
P43: Present and simple past tense may both be correct for results, discussion, and conclusion. However, the use of present or simple past tense for results, discussion, and conclusion should be consistent within a paper.
2.数字和其后单位之间是否需要空格?
P203:Use numerals with units of time or measure, and use a space between the numeral and the unit, except %, $, º(angular degrees), (angular minutes), and (angular seconds).
〔也就是数字和%, $, º(角度), (上角分)和(上角秒)之间不用空格〕
3.数字是用阿拉伯写法,还是英文字母写法?
P203:With items other than units of time and measure, use words for cardinal unmber less than 10; use numerals for 10 and above. (也就是10以下数字用英文字母数字写法,10和10以上的用阿拉伯数字写法)
Spell out ordinals "first" through "ninth"; use numerals for 10th or greater.
