in order to probe into whether glycine supplementation plays an adjusting role in sports performance and immune functions, the authors divided 30 mice randomly into an exhaustive exercising group (e1), glycine supplemented exhaustive exercising group (e2) and a normal resting control group, with 10 mice in each group, supplemented glycine to mice in group e2 and physiological saline to mice in the other two groups, let mice in groups e1 and e2 do an exhaustive swimming exercise 4 weeks later, applied the trace ch50 hemolysis method to analyze supplement activity, applied the mtt method to perform a quantitative analysis on the lymphopoiesis ability of spleen, and thus revealed the following findings: compared with mice in group e1, the time taken by mice in group e2 to swim to an exhausted state is significantly longer (p.05); total supplement activity in blood serum of mice in group e1 is significantly lower than the same of mice in group s (p＜0.01), and total supplement activity in blood serum of mice in group e2 is significantly higher than the same of mice in group e1 (p.01), but still significantly lower than the same of mice in group s (p.05); as observed from the test of the lymphopoiesis ability of spleen, the lymphopoiesis ability of spleen of mice in group e1 is significantly lower than the same of mice in group s, and the lymphopoiesis ability of spleen of mice in group e2 is significantly higher than the same of mice in group e1, but still significantly lower than the same of mice in group s.

四型肽精氨酸脱氨酶在类风湿性关节炎。。。以马来酸酐与氨水为原料热缩聚法合成。。。摘要：为探讨甘氨酸补充对运动能力及免疫功能是否具有调节作用，将30只小鼠随机分成力竭游泳运动组(e1)、甘氨酸补充后力竭游泳组(e2)和静息正常对照组，每组10只。在e2组补充甘氨酸，其余两组给予生理盐水，处理4周后，e1组和e2组均做力竭性游泳运动。采用微量ch50溶血法分析补体活性，采用mtt法定量分析脾脏淋巴细胞增殖能力。结果显示，与e1组比较，e2组游泳至力竭的时间显著延长(p＜0.01)。e1组血清总补体活性显著低于s组(p＜0.01)，e2组显著高于e1组(p.01)，但仍显著低于s组(p.05)。在脾脏淋巴细胞增殖试验中观察到，e1组显著低于s组，e2组显著高于e1组但仍显著低于s组。

It was important that the thixotropic agent,surface active agent and solid lubricating agent are added,the surface of magnetizable particles were suitable treated,at the same time,the stability and lubricating property of MRF were analyzed and discussed.

We investigate the lower bounds of concurrence for tripartite, and even multipartite quantum mixed states in Sec.

在本文的第四部分，通过寻找Concurrence与推广的部分转置之间的关系，我们给出了三体及多体量子态Concurrence的一个下界，这个下界是易于计算的。

Diamond is octahedral cleavage, that is four directions of a plane octahedral crystal and is generally in a ladder shape.

钻石为八面体解理，即平面八面体晶面的四个方向，一般呈阶梯状。

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。

The spikes per plant of diploid and tetraploidspecies were higher, but the kernels per spike, 1000 kernels weight and grain yield werelower than those of hexaploid and octoploid species. The NYE, NHI and NPE of diploidand tetraploid were lower; NDE was higher than these of Hexaploid. Variation of NPE andNYE was higher than other NUE indexes, which indicated that NPE and NYE could beused as indexes for NUE differences in different wheat related species.

与普通小麦相比，二倍体和四倍体材料单株穗数较多，但穗粒数、千粒重和产量比较低；氮素籽粒生产效率、氮素收获指数和生理效率比较低，具有较高的氮素干物质生产能力；NYE和NPE的变异性较大，可以作为小麦不同近缘种氮素利用效率差异的主要指标。
