• Abstract : robertsonian translocation is important in the study of evolution biology . current progress , contents , technology and methods about robertsonian translocation studies are introduced in the article . the usefulness in improving the breeds of pasturages and molecular genetic aspect are also discussed
  摘要本文总结了罗伯逊易位研究的现状、内容和技术方法,并对它在畜牧品种的改良、分子遗传学方面的应用作了探讨,指出了它在研究进化生物学方面的重要意义。
• According to the valuation of 1831 , there were in concord two thousand one hundred and eleven acres , or about one seventh of the whole territory in meadow ; this standing next in the list after pasturage and unimproved lands , and , judging from the returns of previous years , the meadow is not reclaimed so fast as the woods are cleared
  根据1831的评估，康科德有两千一百一十一英亩的土地，整个区域大约有七分之一处于草甸中；这些未砍伐的区域位于牧场和未耕种土地之外的田垄里，并且以前一年的结果来看，树木一旦被砍伐掉，草甸就无法再生了。
• They have great potentialities to ecological restoration and high value to being used as forage . however researches on their physiological characteristics related to drought adaptabilities were not sufficient , yet . therefore , it is necessary to reveal more properties in order to increase efficiency in the ecological practice and to promote using in pasturage
  驼绒藜属( ceratoides )植物为干旱、半干旱地区具有重要生态价值和饲用价值的旱生半灌木资源，对该属植物适应干旱生理特性的研究尚不充分，加深研究有助于提高对它们的利用效率和应用价值。
• The answers given by this theory to historical questions are like the answers of a man who , watching the movements of a flock , should pay no attention to the varying quality of the pasturage in different parts of the field , nor to the actions of the shepherd , but should look for the causes of the flock taking this or that direction simply in the animal that happened to be foremost in it
  一个人看见一群牲口移动，而不注意不同地区的不同性质的牧场，也不注意牧人的驱策，就断言那群牲口之所以从这个方向或从那个方面走动是由于那头牲口引路的缘故，这个人的答案就跟那种理论对历史问题的答案一样。
