In this study, genetic analyses were conducted to determine the genetic basis in an elite resistant inbred line Siyi with complete resistance to maize dwarf mosaic. A new genetic model, two dominant complementary genes conditioning the resistance, were found by Mendelian genetic analysis based on parents, F1, F2 and backcrosses in three successive years' field trails. The two genes were further mapped near the centromere of chromosome 3 and 6, respectively by tightly linked microsatellite markers using 242 plants from F2 generation. The resistance gene on chromosome 3 is 1.0 cM apart from the flanking markers phi053 and umc1527, respectively. Whereas the linkage distance between two flanking markers bnlg1600 and phi075 and resistance gene on chromosome 6 was 1.0 and 4.0 cM, respectively. Genotypic analysis of the plants from testcross and F3 populations supported the new genetic manners.

课题组通过连续三年的抗病鉴定，在国内种质资源中筛选出一份综合农艺性状优良、配合力较高的自交系四一，三年的表型遗传研究和两年的分子标记工作，发现四一中的玉米矮花叶病抗性是由两对显性互补基因控制的，进而利用F2作图群体，把发现的两个基因定位在第三和第六染色体的着丝点附近，并获得了双侧紧密连锁的分子标记连锁图谱，其中第三染色体上的分子标记UMC1527和phi053从抗病基因双侧逼近1 cM，而第六染色体上的分子标记phi075、bnlg1600从抗病基因双侧分别逼近4 cM和1 cM；利用B2群体、F2：3家系、BC3F1群体和带有第三、第六染色体抗病基因以及两个抗病基因的近等基因系，进一步证实了四一中成株期抗性是由两个显性互补基因控制的。

The optimal conditions for biodegrading two-composition VOCs are temperature of 30℃,pH of 6, flux of 0.055m3/h. The reactor remains rather stable in the course of two-composition biodegradation. The elimination capacity on two-composition VOCs of reactor is higher than that of sole-composition VOC.

The first two chapters showcase the Anti-Rightist Campaign (1957) and "the Great Leap Forward"(1958). Based on the works of Poetry and the poems relevant to the two said political campaigns, these two chapters analyze the ways in which the poems assembled, cohered and acquired referentiality intra-textually and in a wider cultural context. Changes in that formative process provide an effective frame of reference for us to reflect on the losses and gains of the Poetry and socialist literature in a particular time.

Because the practical production and theoretical research in the past treat reheating furnace and roughing mill as two separate facilities, which dissevers the continuity of production process and the interaction on energy consumption of the two facilities, even though the minimal energy consumption may be achieved in a single facility, there is no way to guarantee the total energy consumption minimization of the two facilities as a whole.

由于以往实际生产和理论研究均把加热炉和粗轧机作为两个独立的生产设备进行控制，割裂了两者在生产过程上的前后连续性和在生产能耗上的相互影响性，针对每一个设备的控制即使保证了其自身能耗的最小化，也不能实现将这两者作为一个整体来看待的整个热轧生产线的能耗最小化。

The repulsion is to be expected when the two parallel slabs have different electromagnetic properties. By studying different cases containing ordinary materials and metamaterials, we found that the repulsive behavior may possibly appear when the wave impedances, which are used to demonstrate the difference of electric and magnetic properties between two slabs, are smaller and larger than the impedance of vacuum, respectively, and moreover, the greater the difference between two wave impedances, the more easily the repulsive force is obtained.

排斥的Casimir作用力只可能出现在两不同平板的情况中，而通过考察正常材料与特异材料介质的不塑料托盘同组合情况，我们发现板间媒质阻抗的值介于两板的阻抗之间且两板阻抗比与板间媒质的差异越大，Casimir排斥力越容易产生。

The aptitude and career interest were considered as the two dimension of the entrance guide system, and was proof-tested by the structural equation model, which results supported this two-dimension hypothesis. Accordingly, there were two parts in the guide system. One part was about the aptitude test, consisted of seven subtests: verbal reasoning, spatial imagining, mathematic reasoning, computer capacity, abstract reasoning, physical knowledge, and sentence recomposing. The other part was about the career interest test, including eight aspects: career longing, curriculum desire, entertainment after school, activity preference, job preference, work environment preference, self-estimate of one\'s abilities, and discuss future with someone else. After three times modification and testing, the psychometric indices of the guide system were become well and stable. Furthermore, the guide system was primarily launched into applying, with four typical case studies, the practicability and serviceability of the guide system was showed swiftly.The entrance guide system for junior high school students that was developed in this research was one-upping in the entrance guide field in China.
