距离

While matching, only the principal component directions corresponding to the rows of the same serial numbers in searching area are needed to be extracted for the computation of projection value so as to form the vectors of projection values. The distances between MM-vectors and the vectors formed by projection values are computed, and whether the two kinds of vectors are matchable should be in accordance to those distances.

在匹配时，只需抽取搜索区域中相同序号的列向相应的主元方向作投影运算，从而构成投影值向量，进而计算该向量与预处理中所得的最大最小值构成向量间的距离，从而根据距离的大小判断是否匹配。

The moving distance should be limited with the largest change rate of sink node coverage or the mathematical expectation of moving distance.

移动的距离可以采用以汇聚节点覆盖最大变化率限制移动方式和以距离的数学期望限制移动方式进行。

In D3 gene with 5 site mutations. There exists individual variation in the COII gene, but this variation is less than that among other members of Myzomyia Series such as An. aconitus, An. jeyporiensis, etc. In addition, one haplotype different from both An. minimus A and C was found in these 3 genes studied.②The genetic distance between An. minimus A and An. minimus C is less than that among other members of Myzomyia Series. Molecular trees based on different genes and different methods show that An.

种系发生研究表明，微小按蚊复合体亲缘种A、C间的遗传距离远小于与之近缘的同系其它成员间的距离。2个分子标记3种方法构建的基因树显示，微小按蚊A、C的种系地位非常固定，不同地域来源、不同变异类型的微小按蚊始终在同一分"枝"上，与迈蚊系其它成员相比，呈现其相对稳固的单源性。
