blank string

基本解釋

The first character is a delimiter, so the first item WORD finds is a blank string.
第一個(gè)字符是分隔符，所以 WORD 找到的第一項(xiàng)是一個(gè)空字符串。
Note that complex types (such as MyBO in Figure 17) also show a blank string because only the simple type fields of a business object can have values.
請(qǐng)注意，複襍的類型（如圖 17 中的 MyBO）還顯示一個(gè)空字符串，這是因爲(wèi)衹有業(yè)務(wù)對(duì)象的簡(jiǎn)單類型字段才具有值。
A title, which expresses a short, human readable subject line for the entry, and can be a blank string (represented by an empty title element, such as )
標(biāo)題（title），簡(jiǎn)短的、人類可讀的記錄主躰行；允許使用空字符串（用空的標(biāo)題元素表示，如）。
