The first and second longest chromosomes are important in karyotype analysis and most of which are metacentric chromosome and submetacentric chromosome in lilium . hybrids were distinguishable by the existence and position of secondary constriction and arm ratio 百合的第一对和第二对染色体多为中着丝粒和近中着丝粒染色体，可以根据次缢痕有无与位置及臂比鉴定杂种。
The influence of the melt transfer temperature , spinning temperature , temperature and speed of quench air , the 1st hot rolls temperature , the 3th hot rolls temperature , drawn ratio on dying property of melt direct spun fdy were discussed 摘要主要就熔体直接纺fdy生产过程中熔体输送温度、纺丝温度、侧吹风温度、风速、第一对热辊温度、第三对热辊温度、拉伸倍数等因素对染色性能的影响进行探讨。
By its perfect shape , its vigour , and its natural dexterity in the use of all its untried limbs , the infant was worthy to have been brought forth in eden ; worthy to have been left there , to be the plaything of the angels after theworld s first parents were driven out 达婴儿体形完美精力旺盛，在她稚嫩的四肢的动作中具有天生的灵活，称得起是出生在伊甸园中的可说是在世上第一对父母被逐出之后，留在园中当作天使们的玩物的。
Concatemer were constructed by polymerization with t4 dna polymerase and primer - templated pcr with high fidelity dna polymerase . one concatemer of 360bp , 9 copies of grb - ast3 , were obtained from the first pair of primer and three ones of 515bp , 750bp , 792bp , from the second one 从第一对引物的拼接产物中克隆到一个360bp含有9个拷贝数的grb - ast _ 3的串联体，从第二对引物的拼接产物中克隆到三个分别为515 、 750 、 792bp的grb - ast _ 3的串联体。
This showed that the diploid chromosome number ( 2n ) of amphioxus b . belcheri tsingtauense was 36 . the chromosomes were extremely small , ranging from 1 . 4 to 3 . 7 um in length . the first pair of the 36 chromosomes of b . belcheri tsingtauense was subtelocentric and the other 17 pairs telocentric . neither metacentric nor submetacentric chromosomes nor satellites were observed 在36条染色体中，除第一对染色体属亚端部着丝粒染色体( st )外，其余均为端部着丝粒染色体( t ) ，未见中部着丝粒染色体( m )和亚中部着丝粒染色体( sm )及随体。
By rt - pcr method . we first selected a pair of primers named 2bp and 4bm which was designed in highly conserved 922 nucleotide region in open reading fram ( orf ) ib from coronavirus . this primer could amplify 11 kinds of coronaviruses . after synthesizing this pair of primers , we amplified the target fragement of 251bp from the panda ' s liver - tissue materials and other different passages of culture of this virus . however , the control cell showed negative result 第一对引物为外层引物，可扩增出1086bp的核酸片段；第二对引物为内层引物，可扩增出515bp的核酸片段。该引物以k378为参考株，含有多个兼并碱基，可扩增出包括k378 、 insavc - 1 、 ccv1 - 71 、 nvsl吉林农业大学硕士学位论文大熊猫犬冠状病毒的分离鉴定及s墓因部分序列的测定和分析等多种犬冠状病毒。
Effect of napthalene ( nap ) and pyrene ( pyr ) different concentration on hypocotyl germination of kandelia candel in sand culture is obvious . hypocotyl germination of kandelia candel showed no significant difference from control group at concentration of 0 . 1mg / l for nap and pyr . when at concentration of 1 mg / l and 10mg / l , nap showed a significant inhibition on hypocotyl germination of k . candel , but showed no inhibition on first pair of leaves ; at concentration of 10mg / l , nap showed a significant inhibition on the second pair of leaves Nap浓度为0 . 1mg l对秋茄种苗萌发的影响不明显；在1mg l浓度组对秋茄种苗初期萌发阶段即吐芽有明显的抑制作用，而对第一对叶片和第二对叶片展开影响不明显；在10mg l浓度组对种苗吐芽以及第一对叶片展开没有明显影响，而对第二对叶片展开有明显的抑制作用。
The causes of devolution , desertation , salinization and solonization were analysed in two aspects : it is apparently due to overpopulation , overstocking , unreasonably using , lacking of new technique , frequent occurrence of nature disaster , small area and low output of artificial pasture and semi - artificial pasture , but the more deeply reason was that the function of grassland was not completely understood only emphasizing the economic efficiency and regrowthful resource in grassland while the ecological efficiency and its potential use were neglected 本文主要从两方面对草原三化进行了分析，首先从表面上看有以下几方面原因，人口多、牲畜数量多、草原利用不合理、新技术推广差、草原自然灾害频繁、人工半人工草地少产量低。其次又挖掘了草原退化的深层原因，第一对草原资源的功能和作用的认识具有片面性，只重视草原的经济效益，却忽略了它的生态效益；只重视草原资源的再生性，却忽略了它的适宜可利用性。
