Result In 5 kinds of chemical treatments, treating Z. macrostachya seeds with 20 % NaOH solution for 20 min and then cleaning the seeds with clear water got the best effect of breaking seed dormancy. By this treatment, the seed germination potential reached 83.5% in 10 d, being 58.2 % higher than CK; reached 85 % in 15 d, being 55 % higher than CK, which was near to the potential germination rate of Z. macrostachya seeds. Compared with CK, the germination duration was obviously shortened.

结果］在5种化学处理中，用浓度20%NaOH溶液处理大穗结缕草种子25min，再用清水清洗，对解除种子休眠效果最佳，10d发芽势达83.5%，比对照高出58.2百分点，15d发芽率达85%，比对照高出55.0百分点，已接近大穗结缕草种子的潜在发芽率，发芽历时比对照明显缩短。

During the early growth stage of seedlings, basal stem diameter and paripinnate number were decreased with the increasing of shade, taproot length, root : shoot ratio, total dry weight and leaf area per seedling were maximal under 37.3% NS, specific leaf area was increased with the increasing of shade, but the relative growth rate was declined. Seedlings grew fastest under 0.6% NS, suggesting that nutrients stored in seeds played an important role at the early growth stage. The treatment of 37.3% NS was best for established seedlings in seedling height, basal stem diameter, paripinnate number, rachis length, the maximum sub-leaflet number of individual paripinnate, leaf area per seedling, relative growth rate and net assimilation rate. Light intensity was positively correlated to total dry weight, and negatively to specific leaf area. The maximum of SLA was observed under 15.5% NS.

生长早期的幼苗基径和复叶数随遮荫程度的增加而降低；主根长、根冠比、总干重和单株叶面积均以37.3% NS处理最大；比叶面积随遮荫程度的增加而增大，而相对生长率则降低；幼苗株高在0.6% NS下增长最快，表明种子中贮藏的营养物质对幼苗的早期生长可能具有重要作用。37.3% NS处理对定居后绒毛番龙眼幼苗的生长最有利，幼苗的株高、基径、复叶数、叶轴长、复叶最多小叶数、单株叶面积、相对生长率和净同化率均在37.3% NS处理下获得最大增长；幼苗总干重随光照强度的减弱而降低；比叶面积在15.5% NS处理时最大。

The geometry of canopy and interception of photosynthetically active radiation were measured.

通过实测和理论计算，结果表明：高原地区冬小麦叶片比平原地区的更趋于直立，具有比平原地区低的消光系数，能够容纳较大的绿叶面积和有效穗数；当冠层对PAR的截获率趋于饱和时，高原地区麦田可容纳的最大绿叶面积可达8.6，是平原地区的1.4倍左右；开花到成熟期间的叶日积大约可达平原地区的2倍，绿叶面积持续时间长；整个生长季期间，高原地区的PAR总量是平原地区的1.7倍，单位绿叶面积所截获的PAR是平原地区的1.3倍，又由于其叶片的趋于直立，故从上到下叶片受光比平原地区更均匀和充分，群体光合潜力高，对PAR的利用率更高。

The influences of oxygen,reburn fuel fraction and coal particle size on specific NO reduction quantity were analyzed.

实验与分析结果表明：NO还原效率高并不意味比脱硝量高；NO还原效率随O2浓度降低和再燃燃料比增加而单调增加，但比脱硝量变化规律相对复杂。

The result show that high NO reduction efficiency does not absolutely mean high specific NO reduction quantity; decreased oxygen content and increase reburn fuel fraction lead to increase NO reduction efficiency but not absolutely increase specific NO reduction quantity.

实验与分析结果表明：NO还原效率高并不意味比脱硝量高；NO还原效率随O2浓度降低和再燃燃料比增加而单调增加，但比脱硝量变化规律相对复杂。

It indicated that the end of the CNTs had been opened after it was refluxed 80h.

在50mA/g电流密度下，回流时间越长的碳纳米管材料比容量越高，80h回流得到的电极比容量最大，达到38.3F/g，比回流之前的8.3F/g要高。

Total N increased significantly in the rhizosphere, hut total P and total K decreased. However, the available N, P and K in the rhizosphere behaved in an opposite way: with available N decreased but available P and available K increased in the rhizosphere except fur Phragmites communis Trin. Deficit of available N is the most significant, and accumulation of available P and available K were the least for Salsola nitraria Pall. among all seven halophytes.

在所有研究植物中，根际土壤中全N含量比土体的含量高，但全P和全K含量却比土体的含量低；根际土壤中有效态养分的变化则与全态相反，根际土壤中的有效N含量比土体中的都显著降低，除芦苇外，其他六种盐生植物根际土壤中有效P和有效K的含量都高于土体，但有效P的富集不及有效K富集的程度高。

5Under powerful offensive denfense,failing in resolving the offending problems is one of the leading reasons that it lost in the world men ' s basketball championship;the quantity of the fast attacks from chinese team lags behind a lot,compared with the opponents.Moreover,the difference of the quantity of success,the gap of score and fast attacks after stealing is very obvious; scoring could only be attributed to receive and shoot,play by oneself and free throw.Scoring method is simple and unscattered;strategic offenses lag behind the opponent obviously.Both free throw after active offense and rebound control could not defeat the rivals.The stealing and offense succeeding percentage also fall behind. The offense efficiency lags more behind;the number of two – piont shot lags behind the opponent while the field goal percentage ranks a little higher than opponent.The number of three-point shot is similar, but the field goal percentage is obviously different;chinese team ' s front court rebound falls behind the opponent apparently.However,the second offense scoring is a little higher;chinese team ' s assists lags behind a lot;chinese team ' s stealing lags behind a lot;chinese team ' s turnovers distingguish a lot with opponents.

在强对抗的攻击性防守下中国队不能解决好进攻的问题是世锦赛失利的最主要的原因之一；中国队的快攻次数与对手的差异具高度显着性，成功次数的差异具显着性，得分的差异具高度显着性，断球后发动快攻的差异具显着性；得分主要集中在接球得分、单打得分、和罚球得分这三个方面，得分手段单一而且集中；战术进攻与对手呈差异有高度显著性，作为主动进攻的罚球和争夺篮板球都比对手低；抢断与对手的的差异具显着性，进攻成功率与对手的有一定的差距，进攻效率的差距更大；2分球的投篮次数与对手的具有高度显著性差异，命中率比对手稍高一点，3分球投篮次数相当，命中率具有显著性差异；中国队的前场篮板球与对手相比具有显著性差异，但是二次进攻得分却比对手略高一点；中国队与对手的助攻相比有显著性差异；中国队的抢断与对手相比具有高度显著性差异；中国队的失误与对手相比具有高度显著性差异。

The grafting effect and mechanism was charac- terized by FTIR,The heat stability of unvulcanized and dynamical mechanical proper- ty of vulc- lcanizates of SBR and SBR-g- were tested by TG and DMA respectively. medium-resistance properties of SBR and SBR-g- vulcan- izates were also investigated.The results showed that addition of St accelerated GMA grafting onto SBR and control the decomposition of SBR. When the conditions were GMA/St/DCP was 8/4/0.3 and grafting temperature was 160℃.
