Character : it is interweaved by high - quality terylene vole and terlene silk . inner lining is pvc material , which has a low price , and good character of aging proof , water proof , low resistance , quick pulling . soft convenient and long using life , etc , it is a new product , which can take the place of rubber inner lining in some fields 特点：采用优质涤纶纱和高强涤（丙）纶丝为原料，经平纹织机环编交织而成，内衬优质pvc材料，物美价廉，具有耐压，不渗水,水流阻力小，出水快，特别轻便柔软，使用寿命长等特点，是一种新型产品，在部分领域可代替橡胶衬里水带。
The results revealed that : ( 1 ) the zymogram of est isozyme in the livers from all microtus fortis existed widespread polymorphism . they were similar to each other at the i area while quite different at the iii and iv area . at the ii area , the voles from hunan , ningxia and the big voles from heilongjiang were close but the difference between the small voles from heilongjiang and three other groups was obviously 结果表明： ( 1 )东方田鼠的肝est同工酶活性较强，有着丰富的多态性，四类鼠在区较相近，在区和区差异都较大，在区湖南、宁夏和黑龙江大体型东方田鼠较为相似而黑龙江小体型东方田鼠与它们差别较大。
But while it is unlikely that people have a mental , smell - based map of their partners in the way that voles do , there are strong hints that the hormone pair have something to reveal about the nature of human love : among those of man ' s fellow primates that have been studied , monogamous marmosets have higher levels of vasopressin bound in the reward centres of their brains than do non - monogamous rhesus macaques 尽管与田鼠不一样，人类不太可能有一张基于嗅觉的神经系统伴侣图谱，但若干线索已有力说明，这两种荷尔蒙能揭示一些人类恋爱的本质在已被研究过的人类灵长目同伴之中，一夫一妻制小长尾猴的大脑奖赏中枢系统中，抗利尿激素水平较非一夫一妻制的恒河短尾猿高。
Further experiments showed that dopamine restructured a part of the vole ' s brain called the nucleus accumbens , a region that many animals have , including humans . the change was so drastic that when paired - up males were introduced to new females , although their brains still produced dopamine on sight , the chemical was channelled into a different neural circuit that made them go cold towards the new female 当已有配偶的雄鼠被介绍给新的雌鼠时，尽管此时雄鼠的脑中还在继续分泌多巴胺，但多巴胺会被导入另一个完全不同的神经中枢系统，使得雄鼠对新的雌鼠毫无兴趣。
The phylogenetic tree constructed by upgma showed that : the voles from hunan , ningxia and the big voles from heilongjiang could be g athered in one group ( the voles from hunan and ningxia gathered firstly , then gathered to the big voles from heilongjiang ) , but the small voles from heilongjiang were in the other group alone . these results indicated that the phylogenetic relationship among the voles from hunan , ningxia and the big voles from heilongjiang is closer than that between the small voles from heilongjiang and them 四类东方田鼠的upgma聚类分析图显示：湖南、宁夏和黑龙江大体型东方田鼠聚为一类(湖南鼠与宁夏鼠首先相聚，再与黑龙江大体型东方田鼠相聚) ，亲缘关系相对较近；黑龙江小体型东方田鼠单独为一类，与其它三类鼠的亲缘关系均相对较远。
