Based on the national"ninth·five years"key project——study on the equipment and technique of raising and transplanting seedlings as the kind of factory, combining the no-tillage specialty which can shorten the working period and reduce the intension of dust devil, the key parts of corn no-tillage transplanter has been studied which can improve both the transplanting speed and reliability, reduce the labour intension of operator, further more, the method of automatic controlling whole working course has been applied by using single-chip microcomputer, the bedrock is made for transforming this technique into social productivity.

本文在原来国家科技部"九五"攻关项目"工厂化育苗、移栽工艺及设备研究"的基础上，结合免耕工艺不仅缩短作业时间，而且可以对防止沙尘暴发生有利的特点，对可以提高栽植速度和工作可靠性、降低操作人员劳动强度的玉米免耕栽植机的关键部件进行了详细的研究，进一步采用单片机控制技术对其工作过程实现了自动化控制，为该技术尽快转化为社会生产力打好基础。

At present, a lot of systematic and comprehensive research about larger cities have been done by Chinese scholars. But there was rarely dustfall research in Changchun city. There were not only strong theoretical significance but also provide the basic data for the environmental department.and if we can analysis and research on space-time distribution, characteristics and sources of dustfall.

目前我国的学者对一些大中型城市的大气降尘进行了较为系统和全面的研究，但是对长春市降尘的研究却很少，已发表的成果仅有两例，因此对长春市大气降尘的时空分布、特征及来源进行系统的分析和研究不仅具有较强的理论意义，而且还可为环保部门提供基础数据。

Since curly leaf hybrid could be recognized at early stage,and displayedobvious dwarfness,choosing"Zha′ai 76"as paternal parent not only raised thehybrid-selecting efficiency from the pollinated progenies,but also raised thebreeding efficiency of apomctc dwarf roostock of apple.

鉴别宽叶型杂种较难、需时较长(2-3年生时)并需与染色体倍性鉴定法相结合，因其形态变化较小而生长势又与平邑甜茶无融合生殖苗无明显差异；鉴别光叶型杂种因父本染色体组的影响加大而从形态上容易些，但也需过氧化物同工酶法或染色体倍性鉴定法相配合；皱叶型杂种因在苗期刚出1-2片真叶时就表现明显的标志性状、能从叶片形态上准确鉴别出来，毋须染色体倍性鉴定等复杂方法；因皱叶型杂种能早期鉴别，又表现明显的矮生性，因而选用"扎矮76"做父本不仅大大提高了平邑甜茶授粉后代中选择杂种的效率，而且提高了苹果无融合生殖型实生矮砧育种的效率。

Based on this relation, it is possible not only to obtain the principle of virtual work and the reciprocal theorem in dyn...

然后从该式出发，不仅可以得到有孔隙的耦合热弹性体动力学的虚功原理和互等定理，而且能系统地导出成互补关系的11类变量、9类交量、6类变量及3类变量简化Gurtin型变分原理。
