逻辑记录长度格式档案中每个逻辑与实体记录长度，以字节（即字段）为单位。
The length, in bytes (i. e. , columns ), of a logical and physical record in a logical record length formatted file.
一个长方形档案中，每笔受访者的记录或是每个分析单位都包含相同的卡数或是相同的实体记录长度。
A rectangular file is one which contains the same number of card-images or the same physical record length for each respondent or unit of analysis.
为了让这种档案有一个相同的实体记录长度，短的逻辑记录会用空白填补，因此他们的实体记录长度相同。
In order to give such a file a common physical record length, short logical records are typically "padded" with blanks so that they will all be the same physical record length.
所以当每笔数据或是每一分析单位被储存在一笔实体记录时这种档案结构就称为”逻辑记录长度”。
Thus, when the data for each case or unit of analysis is stored in a single physical record, the file structure is called "logical record length."
