The absence o. netwo.k infrastructure and o.po.tunistic spectrum access in co.nitive radio.ad ho. netwo.ks （CRAHNs） results in co.nectivity and stability pro.lems. Clustering is kno.n as an effective technique to.o.erco.e this pro.lem. Clustering impro.es netwo.k perfo.mance by implementing a lo.ical netwo.k backbo.e. Therefo.e, ho. to.efficiently co.struct this backbo.e amo.g CRAHNs is o. interest. In this paper, we pro.o.e a new clustering algo.ithm fo. CRAHNs.

To.the best o. o.r kno.ledge, this is the first attempt to.mo.el the channel hetero.eneity into.the clustering fo.matio. in co.nitive radio.netwo.ks.

Stepper mo.o. driven systems are widely used in industrial applicatio.s. They are mainly used fo. their lo. co.t o.en-lo.p high perfo.mance. Ho.ever, as dynamic systems need to.be increasingly faster and their mo.io. mo.e precise, it is impo.tant to.have an o.en-lo.p system which is accurate and reliable. In this paper, we present a no.el technique in which a genetic algo.ithm （GA） based lo.kup table appro.ch is used to.find the o.timal stepping sequence o. an o.en-lo.p stepper mo.o. system.

根瘤固定的氮素是大豆植株生长发育的重要氮素来源,植株的固氮能力会影响氮素吸收效率,从而影响产量。大豆又是需水较多的作物,干旱会给大豆生长发育造成很大影响。在干旱条件下,施用适量的氮肥,在一定程度上能保证大豆的正常生长和产量的形成。本试验在盆栽条件下将干旱与施氮处理结合起来,采用超高产品种辽豆14号通过研究大豆开花期至鼓粒期的根系形态,根系的结瘤固氮生理和产量形成等,探究施氮对干旱胁迫下大豆的根瘤固氮和产量形成的影响,试图揭示超高产大豆品种对干旱胁迫下施氮的反应,为未来干旱胁迫下的大豆抗旱生理育种提供理论依据。主要结果如下:1.干旱条件下辽豆14的根表面积、根体积和根直径均低于正常水分处理,根系长度长于正常水分处理。大豆盛花期和盛荚期,辽豆14的根直径先增加后降低,根体积会逐渐增加;大豆鼓粒期辽豆14的根直径呈现逐渐增加趋势。R1期追肥处理下,根体积会先增加后降低。说明辽豆14的根系在施用氮肥后其吸收利用水分和养分的能力更强。2.干旱条件下辽豆14的根瘤鲜重、根瘤数均会降低,N100施肥水平会促进辽豆14的根瘤生长,N150施肥水平下,辽豆14在R1期追肥处理下的根瘤鲜重有所增加,其余均会受到抑制。干旱会降低根瘤的固氮酶活性和豆血红蛋白含量,且随着施肥水平的提高会逐渐降低。鼓粒期辽豆14在干旱条件下不施肥处理的固氮酶活性降低了24.79%,施用底肥和R1期追肥处理均低于不施肥处理。本研究表明,豆血红蛋白含量变化和固氮酶活性变化具有一致性。说明干旱条件下,辽豆14的根瘤固氮会受到抑制,施氮后抑制增强。底肥N100和R1期追肥N100处理可以降低干旱对根瘤数的影响,不同生育时期的平均根瘤数分别为170.3个/株和156.8个/株,而不施肥的对照仅为101.5个/株。底肥N100、底肥N150和R1期追肥N100处理可以降低干旱对根瘤固氮酶活性的影响,不同生育时期的平均根瘤固氮酶活性分别为281.4、244.6、210.7 n mo. CH/mg/h,而不施肥的对照仅为186.5n mo. CH/mg/h。干旱会显著降低大豆的豆血红蛋白含量,底肥和R1期追肥会增大豆血红蛋白含量的下降幅度。底肥施氮各生育时期平均含量0.43mg/g No.ule,R1追氮为0.32 mg/g No.ule,不施氮的为0.54 mg/g No.ule。3.干旱条件下辽豆14的根干重、地上部干重和根冠比均会降低,施氮在一定程度上改善了大豆植株在干旱条件下的根冠分配比例,植株根冠比增加。4.干旱条件下辽豆14的结荚高度、株高、节数和分枝数均会降低。在干旱条件下,底肥施氮和R1追施氮肥均可以缓解干旱的减产效果,以R1追肥氮肥效果更好,特别是R1追施N150的效果最佳,两年平均单株粒重为26.51g,不施肥为15.94g。

本研究旨在研究海尔的产品和影响消费者最终决定购买他家产品胜过其他品牌产品的因素。结果表明,海尔品牌虽然还没有达到众所周知的标准,但是客户肯定的表示海尔的产品质量确实是非常的可靠。广告是极大地影响并推动购买者决策的一个主要因素,但产品价格低廉是却是海尔品牌的优势所在。如今的当务之急是海尔需要大规模增加其广告活动,改善其产品质量以及保持价格稳定,因为价格低廉是它目前的主要优势。最后我认为,海尔集团必须拿出创新的营销技巧,以改善其品牌形象。
