The results showed that N uptake of diploid andtetraptoid were lower than those of Hexaptoid and octoploid at over wintering and afteranthesis, but the capability was higher from jointing to anthesis. Diploid and tetraploid hadlower N distribution in leaf, and had higher N distribution in else vegetative parts at anthesis. And had lower N distribution in grain, higher N distribution in else vegetativeparts at mature. The N transfer amounts and its contribution to grain N accumulation ofDiploid and tetraploid were higher than Hexaploid, but the NTE and contribution of Naccumulation to grain N were lower.

结果表明，与普通小麦和小黑麦相比，二倍体和四倍体材料在越冬前和花后氮素吸收能力较低，在拔节到开花期间较高；开花期氮素在叶片中的积累较少，其他营养器官积累较多，成熟期营养器官中的氮素分配较高，籽粒中氮素分配较少；具有较高的氮素运转量，但运转效率比较低；花后营养器官氮素运转对籽粒氮素积累的贡献率较高，花后吸收氮素的贡献率较低。

Taking HPAM solutions as an example , the unsteady flow of power-law fluid in eccentric annuli with the inner cylinder reciprocating axially is calculated; the distribution of velocity, flow rate and:stress distribution on the outwall of the inner cyinder is obtained; the effect of eccentricity, stroke and frequency on distribution of velocity is analysed; the effect of eccentricity and axial movement on stress distribution on the outwall of the inner cylinder is analysed too.
