被任意取代的
直译为：R1、R2、R3、R4、R5及R6分别为氢、被任意取代的酰基、被任意取代的烷基、被任意取代的烷氧基、被任意取代的酰氨基、…
(acyl = R-CO-)
建议译为：R1、R2、R3、R4、R5及R6分别为氢、含各种取代基的酰基、含各种取代基的烷基、含各种取代基的烷氧基、含各种取代基的酰氨基、…
“含各种取代基”的意思包括取代在某一位置的各种不同的取代基，也包括取代在不同位置上的同一种取代基。例如"optionally substituted propyl"可以是第2位被氯或溴取代的丙基，也可以是第2位或第3位被氯取代的丙基，还可以是第2位被氯取代而第3位被溴取代的丙基，故谓"optionally substituted"。

Hydrogen is a special case of 取代基 Rn. In some U.S. patents, the following patern is often used:
\"wherein R1 is selected from a group of C0-C8 alkyl\" (the numbers 0 and 8 are subscript).
\"C.sub.0 alkyl\" is actually hydrogen, i.e., the number of carbon atomes in R1 is zero.

有 必 要 做 语 法 分 析 ：
optionally substituted acyl,和 H 是 同 位 语 。
Substituted 表 明 alkyl， ETC， 是 被 H 取 代 的
