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。

The influence of recessing in adh es ive layer with high elastic modulus on the peak stress of joint is not evident so that it would improve the actual strength of joint markedly based on the load bearing ability not being affected evidenly . On the other hand , the recessing in the joint with low elastic modulus adh es ive caus es the peak stress es increase evidently that may decrease the nominal and actual strength of the joint markedly .

对胶层和被粘物中应力分布的数值分析结果表明：胶层中的间隙对接头端部的应力分布无明显影响，但对间隙附近的应力峰值影响较大；随着胶粘剂弹性模量的增大，间隙附近的应力峰值有所降低；对于高弹性模量胶粘剂接头，胶层中的间隙对接头的应力峰值无明显影响，在不降低接头名义强度的同时可使得接头的实际强度显著提高；而对于低弹性模量胶粘剂接头，间隙使得接头上的应力峰值明显上升，可能导致接头的名义强度和实际强度显著降低。

On bright, calm days they lie in thousands on the now darkening water, mostly yellow flotillas of poplar, floating continuously down from great trees that themselves shake in the windless air with the sound of falling water , but on rainy days or after rain they seem to swim or be driven away, and nothing remains to break the surface except the last of the olive-yellow lily pads that in high summer covered every inch of water like plates of emerald porcelain...

当风和日丽时，无数的树叶浮在已经变暗的湖水上，大部份都是白桦叶子，他们一批一批，像黄色的小小扁舟，不断地从高高的树上飘落下来，在无风的空气中轻轻地晃动着，发出如同流水而下的声音。但是在下雨的时候，或者雨过之后，那些浮在湖面上的落叶，仿佛鱼儿一样都游走了，又像是被不知什么驱赶一空，湖面上除了最后的几片黄绿色睡莲叶子，再无一物，而在盛夏里，那些睡莲叶子，如同翠绿晶莹的瓷盘，覆盖着每一寸湖面。
