答案

英文解释是这样的：
Value
Degree of freedom value or table name reference for tabular boundary conditions.To specify a table,enclose the table name in percent (%) signs (for example,D,NODE,TEMP,%tabname%).Use the *DIM command to define a table.
If Value = SUPPORT,you can specify pseudo-constraints when using residual vectors in a modal analysis (RESVEC,ON) or CMS analysis (CMSOPT,RFFB).
VALUE2
Second degree of freedom value (if any).If the analysis type and the degree of freedom allow a complex input,Value (above) is the real component and VALUE2 is the imaginary component.
可以看出,是边界条件的约束值,至于两个个数值,因为有时要用做复数等等,这样value2就是虚部的值了!
