If the sequence is already in the last permutation, then next_permutation reorders the sequence to be the lowest permutation and returns false. Otherwise, it transforms the input sequence into the next permutation, which is the lexicographically next ordered sequence and returns true.

如果序列已经是在最后一个排列中，则 next_permutation 将序列重新排列为最低排列并返回 false；否则，它将输入序列变换为下一个排列，即字典序的下一个排列，并返回 true。

Yellow-throated marten\'s relationship is between Stone marten and Fisher marten.Fisher marten is the first species who was divided from Martes.The second one were Yellow-throated marten and Stone marten.Based on the analysis of the fossil note,Martes came from Central Europe,Fisher marten,Yellow-throated marten and Stone marten belonged to a branch which evolved to temperate zone.Boreal forest martens was another branch which evolved to cold environment.It is suggested that Yellow-throated marten and Fisher martenwere ascertained genus separately.4、By contrasting and analyzing 11 complete mitochondrial control region gene sequences of Mustelidae,the extended termination associated sequence domain、the central domain and the conserved sequence block domain were identified.A extended termination associated sequence(ETAS1) and eight conserved sequence(CSB-F、E、D、C、B、1、2、3) was indicated,and sequence mode was presented.Different kind of short repeat sequences were found between CSB1 and CSB2.With wolf as the outgroup,the phylogenetic evolution relationship of Mustelidae was analyzed using the neighbor-joining method.

For each type of testing, a necessary and sufficient condition is defined, under which a test sequence of an FSM is synchronizable. In this paper a new model—synchroniable digraph is proposed, which can judge whether there exist any synchronizable test sequence for a given specification without synchronization operation, and which can transform its nonsynchronizable test sequence to synchronizable test sequence if the answer is true. A method to judge how to add external synchronization operations in a nonsynchronizable test sequence to change it to synchroniable one is also proposed.

提出了一种新的同步测试序列生成模型——同步有向图，它可以判断一个给定的协议规格是否可以在不需要外部同步操作的情况下，产生同步测试序列；如果可以产生，则此生成模型可以将非同步测试序列转化为相应的同步测试序列；另外此生成模型还可以用来选择为测试系统增加外部同步通道的方法。
