1·These preferential deals violate the principle of "most-favoured nation" (MFN), which holds that any favour offered to one member must be offered to all.
这些特惠协定违背了“最惠国待遇”(MFN)的原则，这种原则认为，给予某成员的任何优惠都必须给予所有成员。

3·Though growth and preferential attachment are necessary in forming the scale-free networks, the two factors cannot ensure that the network is scale-free.
尽管生长和偏好依附是形成无标度网络的必需要素，但是这两个因素并不能保证网络一定是无标度网络。
4·The scale-free networks cannot be formed without preferential attachment in the local events.
因此，没有偏好依附无标度网络是不能形成的。
