By the same token, a Mossad source says that cloak-and-dagger operations still have their uses, even though ultra-modern electronic and biometric skills, used with surprising efficiency by Dubai's police, make such operations, involving wigged disguises and old-style skulduggery, harder to pull off.

同时，摩萨德消息人士表示，尽管迪拜警方使用超级电子设备和计量生物学技术，效率超乎想象，老套的假发和其他装扮很难蒙混过关，但密谋行动还是得手了。

One old man, who has been a close observer of Nature, and seems as thoroughly wise in regard to all her operations as if she had been put upon the stocks when he was a boy, and he had helped to lay her keel —— who has come to his growth, and can hardly acquire more of natural lore if he should live to the age of Methuselah ——told me —— and I was surprised to hear him express wonder at any of Nature's operations, for I thought that there were no secrets between them —— that one spring day he took his gun and boat, and thought that he would have a little sport with the ducks.

有一位老年人，是大自然的精密的观察家，关于大自然的一切变幻，似乎他有充分的智慧，好像他还只是一个孩子的时候，大自然给放在造船台上，而他也帮助过安置她的龙骨似的，——他现在已经成长了，即使他再活下去，活到玛土撒拉那样的年纪，也不会增加多少大自然的知识了。他告诉我，有一个春季的日子里，他持枪坐上了船，想跟那些野鸭进行竞技，——听到他居然也对大自然的任何变幻表示惊奇，我感到诧异，因为我想他跟大自然之间一定不会有任何秘密了。

By the definition of Vague values——the elements in the closed subinterval set of the unit interval [0,1],some new definitions of binary Vague relations,operations of relations,inverse relations,compositional operations and λ-cut relations are introduced.
