obtainable

every modern type of equipment obtainable, all modern types of equipment obtainable, the only modern type of equipment obtainable和the best modern type of equipment obtainable里的obtainable移到modern前面也可以，但不很自然。有时前面并没有all, every等词而obtainable也用在它所修饰的词的后面。例如：He was kind enough to answer my questions and give me information not easily obtainable.把information not easily obtainable改作not easily obtainable information也可以，但不是很自然。
