?? In ? multiplication involving the two-letter symbols for transport properties, use ? a space, enclose them in parentheses, or use the times sign. When ? superscripts or subscripts are present, the symbols can be closed up.

?? 在涉及傳輸屬性的雙字母符號(hào)的乘法中,使用空格、將它們括在括號(hào)中或使用乘號(hào)。當(dāng)存在上標(biāo)或下標(biāo)時(shí),符號(hào)可以閉合。

?? Use a ? space for simple multiplication of functions of the type f(x) (one-dimensional) ? or g(y, z) ? (multidimensional). Close up multipliers to such functions where applicable. ? You may also use additional enclosing marks instead of spaces.

?? 使用空格對(duì)f(x)(一維)或g(y, z)(多維)類型的函數(shù)進(jìn)行簡(jiǎn)單乘法。在適用的情況下,閉合此類函數(shù)的乘數(shù)。亦可使用附加的封閉標(biāo)記代替空格。

?

?? 當(dāng)數(shù)學(xué)符號(hào)用作形容詞時(shí),也就是說(shuō),使用一個(gè)不屬于數(shù)學(xué)運(yùn)算的數(shù)字時(shí),不要在符號(hào)和數(shù)字之間留空格。
