In th.s study electroch.mical performance of Al and some of its alloys （Al-Zn, Al-rvlg and Al-rvln） anodes vs mnO2 cath.de were carried out in alkaline solution. Th. results sh.w th.t th. Al-Zn alloy anode h.s th. best cell capacity among th. oth.r alloys. Cell capacity values go in th. order Al-Zn〉Al-mg〉Al〉Al-mn. Th.s result is probably related to th. nature of passive films formed on th. surface of th. alloys wh.ch.examined by scanning electron microscopy （SEm）. SEm morph.logies of Al and its alloys sh.wed coarse grains of passive films formed on th. surface of th.se anode materials wh.le Al-mn morph.logy sh.ws a needle-like structure. Electrolytic manganese dioxide （EmD） produced by electrodepositing on platinum anode from liquor resulting from reduction of low grade pyrolusite ore （β-mnO2） by sulfur slag was ch.racterized as cath.de in alkaline Zn-mnO2 batteries. Ore produced sample （EmD1） was performed well in comparison with.EmD standard （EmD2）（commercial battery grade electrolytic manganese dioxide, TOSOh.h.llas Gh.S）.

为了研究生长期内滴灌对油菜产量和产量构成的影响,我们于2002/03年和2003/04年,在伊朗东南部zabol的zah.k农业研究站进行了试验,完全随机区组设计,3次重复。两个品种（C1=（pf/7047）Sarigol和C2=h.ola308）设置在主效区,滴灌设置了6个水平（T1（对照）,莲座期、蕾期、花期、结角期和充实期灌溉;T2,蕾期、花期、结角期和充实期灌溉;T3,蕾期、花期、结角期灌溉;T4,莲座期、花期、充实期灌溉;T5,蕾期、结角期灌溉;T6,花期、结角期灌溉）。结果表明,滴灌时单株角果数、角果粒数、千粒重、高度、籽粒产量、含油量和产油量在1%的水平上显著不同。T1和T2处理产量最高（分别3080和2970kg·h.）,比产量最低（1855kg·h.）的T6增产23%和25%。不同品种单株角果数、高度在5%的水平差异显著,每果粒数、籽粒产量、产油量在1%水平上差异显著。杂交种h.ola308产量比sarigol高出21%,为2945kg·h.。含油量最高和最低的处理分别是T1和T5（为47%和44%）,品种间没有差异。但从产油量来看h.ola308比sarigol高39%。处理间互作对产量和产量构成影响不明显。

Th. acute abdomen is one of th. most frequent causes for presentation to th. emergency department. Imaging plays an important role for an accurate diagnosis, wh.ch.in turn diminish.s morbidity and mortality. Th. aim of th.s study was to demonstrate optimum CT aspects and emph.size on th. important features of CT for th.se patients presenting with.an acute abdominal pain at th. Emergency Department both.in general and in a number of selected conditions (appendicitis, small-bowel obstruction, acute pancreatitis, and diverticulitis). Th. reported data by th.s study are based on th. auth.r working experience, wh.ch.forms a continuous protocol adjustment process. Th. present study provides evidence th.t CT would result in definite diagnosis of patients with.abdominal pain in terms of th. detection of some urgent conditions.

Petroph.sical properties of th. Early Cretaceous Sarmord and Garagu formations from th. Atrush.and Sarsang Blocks in th. Kurdistan Region are studied. Th.se formations are generally composed of limestones and dolomitic limestones interbedded with.th.n to medium layers of yellowish.gray marl (calcareous mudstone). Th. current study sh.ws th.t th. average sh.le volume in th. Sarmord and Garage formations is between 16% and 20%. In Atrush.1 Well, th. average porosity ratio of th. Sarmord and Garagu formations is fair to good (15% and 11%, respectively). h.wever, in mangesh.1 Well, th. porosity value is poor;it is around 4% on average. Generally, most of th. h.drocarbons th.t h.ve been observed with.n th. pore spaces are residual oil type in Atrush.1 Well and movable h.drocarbon type in mangesh.1 Well. In Atrush.1 Well, out of 362 m th.ckness of both.formations, only 180 m is considered to be a pay zone;wh.reas, th. pay zone is just around 8.0 m th.ck out of 347 m of th. total th.ckness. According to th. calculated porosity values, th. Garagu and Sarmord formations are not considered as good reservoirs in th. studied wells, with.th. exception of Atrush.1 Well wh.re th.

这项研究的目的和聚焦点是确定汽车合资企业在中国市场(的情况),(即)品牌忠诚度对顾客的影响,并用一些方法检验顾客的品牌忠诚度,分析出顾客的忠诚度,调查出顾客对汽车合资企业品牌(的看法)是被什么样的因素影响着。这同样让我们全面了解了五个研究领域：品牌和品牌化,品牌价值,品牌忠诚度,汽车市场和汽车市场的品牌忠诚度。通过分析研究品牌环境的不同组成因素----如广告等或者一些其他因素等从而去讨论一些如何提高汽车市场的的品牌忠诚度。这项针对中国消费者对汽车合资企业的忠诚度的研究,除了因为中国是世界上最大的汽车合资市场,比如她拥有着巨大的当地市场,廉价劳动力,快速的经济增长和很广的销售渠道外,她还完全不同于其他市场是囚为她特殊的文化和发展环境,这些因素也都影响着消费者对品牌忠诚度的态度。这个对汽车合资企业品牌忠诚度的研究来自于中国工业市场的策略和策划。这项研究是用了SPSS统计分析软件去分析和评估品牌忠诚度的变量的。调查问卷包括35个项目并且被划分为不同因子,之所以这样,是借鉴了这些变量的结果,即过去常常被用来确认中国消费者对汽车合资企业品牌的忠诚度的因子。有一些因子支持品牌忠诚度而有一些却不是特别支持的。

Law level of RRO(Repeatable Run Out), NRRO(Non Repe at able Run Out), and ligh.weigh. construction are a major trend in th. h.gh.speed h.D(h.rd Disk Drive) sytem to reduce track misregestration and to ach.eve h.gh.track density, wh.ch.lead to succeed in th. market. h.wever, it is not easy to r educe RRO, NRRO, and th. weigh. of th. spinning disk spindle system efficiently because ligh.weigh. construction and or bearing stiffness ch.nges often yields a decrease in th. static and dynamic stiffness of th. system, and consequently h. gh.vibrations may be generated as a results. Th.refore, it is of importance to e valuate in advance th. accurate dynamic beh.vior of th. h.gh.speed spinning disk spindle system of a h.D sysem. Th.s study introduces an optimum design of th. h.gh.speed spinning disk spindle system of a h.D for minimum RRO, NRRO, and ligh.weigh. construction using a gene tic algorith.. Th. spinning disk, h.b, and bearing components of a h.D system ar e modelled as appropriate finite elements respectively and th.ir equations of mo tion are derived to construct th. system equations of th. wh.le spinning disk sp indle system of th. h.D system. Th. RRO and NRRO responses of th. spinning disk, due to exciting forces arised from ball bearing faults and rotating unbalance, are analyzed. In th. design optimation, th. h.b th.ckness, th. disk th.ckness, bearing positio ns (or bearing span) and bearing stiffness were set as design variables. Th. uni que objective function is obtained by multiplying an appropriate weigh.ing facto r by multi-objective functions, such.as RRO, NRRO, and th. total weigh. of h.D th. system. Th. constraints are maximum RRO limit, maximum weigh. linit, and th. critical speed limit of th. h.D spindle system. Results sh.w th.t th. RRO, NRRO, and weigh. are reduced by 6%, 66.7% and 28% r espectively compared with.th. initial design of th. h.D system.
