In the research on the backward-wave oscillation suppression the startoscillation current which is derived from Two-wave theory approximately is given up. Four typical un-uniform slow wave structures start-oscillation current equations are derived by backward-wave amplifing gain expressions with the Two-wave theory. Then the start-oscillation current rates I〓/I〓 between ununiform circuit and uniform circuit of the four structures have been got.

在返波抑制问题的研究中，从二波理论出发，抛弃了二波理论中从起振条件出发来得到起振电流近似表达式的方法，而是利用二波理论的基本关系式分别推导出了四种典型实用的非均匀输出线路的返波增益表达式，采用计算返波增益的方法来得到四种非均匀输出线路的起振电流与均匀输出线路起振电流的比值I〓/I〓。

As compared with the traditional irrigation-traditional fertilization, the following results of the improved optimized irrigation-optimized fertilization were obtained: significantly higher nitrogen use efficiency; the like tiller number per unit area, percentage of the tiller ear number/the tiller number, the ear number per unit area, the greatly reduced grain number per ear, and significantly heavier weight of 1, 000 grains; a trifle taller plants; shorter base internode length, a bit more weight per unit internode length, longer internode length under ear; almost the same LAI values in middle and later stages; coincident process of dry matter accumulation from straight growth onwards, a little more dry matter accumulation amount from earing to maturity; a little longer flag leaf, 2〓 leaf, 3〓 leaf (but the three leaves were shorter than those of the optimized irrigation-traditional fertilization) and shorter 4〓 leaf from top, a bit reduced total area of these leaves; almost the same leaf thickness, mean canopy leaf tilt angle, light extinction coefficient , ratio of light penetration in the upper, middle and lower parts of the wheat canopy, and fair plant type; almost the same senescence process of flag leaf; and increased root amount in 0-120cm soil layer and smaller rate of progressive decrease of the root length density and root weight density with soil getting deep, which can strengthen the resistance to adverse conditions such as water stress in the later stage.

在优化水肥条件下，冬小麦总分蘖数、成穗率及单位面积穗数与传统水肥比较接近，但穗粒数显著减少，千粒重显著提高；株高稍有增加；基部节间长度缩短，充实度略微增高，穗下节间增长；中后期LAI与传统水肥的LAI值基本吻合；起身至成熟干物质积累量动态变化过程与传统水肥十分接近，但抽穗至成熟所形成的干物质量增加；上三叶变长（但上三叶长度增加幅度小于优化灌溉-传统施肥处理），倒4叶变短，总叶面积略有减少；叶片厚度、冠层平均叶倾角、消光系数、冠层各层的透光率与传统水肥差异很小，株型较好；旗叶叶绿素含量动态变化与传统水肥十分接近；0-120cm土层的总根量明显增加，上层根群和深层根群的差异最小，有利于提高小麦后期的抗逆力。

As compared with the traditional irrigation-traditional fertilization, the following results of the improved traditional irrigation-optimized fertilization were obtained: reduced tiller number per unit area, lower percentage of the tiller ear number/the tiller number, the decreased ear number per unit area, the greatly reduced grain number per ear (1999-2000) and like weight of 1, 000 grains; almost the same plant height; shorter base internode length, a bit more weight per unit internode length, longer internode length under ear; lower LAI values in middle and later stages; coincident process of dry matter accumulation from straight growth onwards, a little more dry matter accumulation amount from earing to maturity; shorter and thicker flag leaf, 2〓 leaf, 3〓 leaf and 4〓 leaf from top, reduced total area of these leave; bigger mean canopy leaf tilt angle, smaller light extinction coefficient , higher ratio of light penetration in the upper, middle and lower parts of the wheat canopy, and tighter plant type; almost identical dynamic change of flag leaf chlorophyll content; and almost the same root amount in 0-120cm soil layer, smaller rate of progressive decrease of the root length density and root weight density with soil getting deep and relatively increased root amount in deeper soil layers.

在传统灌溉-优化施肥条件下，冬小麦单位面积总分蘖数比传统水肥减少，成穗率降低，单位面积穗数有所减少，穗粒数、千粒重无显著性差异；株高基本无变化；基部节间长度缩短，充实度略微增高，穗下节间增长；中后期叶面积指数略低于传统水肥；起身至成熟干物质积累量动态变化过程与传统水肥十分接近，但抽穗至成熟形成的干物质量增加；旗叶、倒2叶倒3叶、倒4叶叶长及总叶面积有所减少，叶片相对增厚；冠层平均叶倾角大，消光系数小，冠层各层的透光率较高，株型紧凑；旗叶叶绿素含量动态变化与传统水肥十分接近；0-120cm土层总根量与传统水肥也差异不大，但根长密度和根重密度随土层深度递减速度较慢，根系在下层土壤的分布相对增多。
