This new method not only reduces the compute, but also needs not apriority information of the targets compared with Wishart classifier.

该迭代方法与基于Wishart距离的迭代分类方法相比，不需要矩阵的求逆运算和矩阵的对数运算，降低了迭代过程的计算量，也不再需要目标的先验信息，扩展了其适用范围。

PAHs ratios are used to identify the source of PAHs, the result showed that the major source of 16 PAHs in Urumqi Xinshi district was coal-bustion and vehicle discharges . Mercury in TSP samples were digested by aqua regia and analyzed by AFS analyzer .The results showed that : the concentration of mercury was 0.869-1.91 ng m-3.Compared with other cities in the rest of the world , the concentration of mercury was very high. The concentration of mercury in heating season was lower than that in no-heating season.

对大气颗粒物样品中的汞，采用王水于特弗龙消解罐中加热消解的方法进行处理，稀酸定容后采用原子荧光光谱法对样品中的汞进行测定，测定结果为。869-1.91 ng m-3，与国外城市相比较高；实验测得非采暖期乌鲁木齐大气颗粒物汞浓度的均值高于采暖期颗粒物中的汞浓度，其原因可能是由于随着非采暖期温的升高，长期积累在土壤、水体环境中的汞向大气中释放，附着在颗粒物上，过了燃煤的影响。

The primary phases of Al-10% Cu, Al-20% Cu Al-40% Cu alloy are nearly equiaxed spherical or rose spherical by semi-solid processing. Compared with the coarse arborization of Al-10% Cu, Al-20% Cu Al-40% Cu alloy of conventional casting, the structure of alloy is extremely improved and the appropriate grain size for the engineering application is obtained.

结果表明：利用半固态加工，可以使Al-10%Cu、Al-20%Cu、Al-40% Cu合金的初生相呈近等轴的球状或蔷薇球状，与普通铸造Al-10% Cu、Al-20% Cu、Al-40%Cu合金较粗大的树枝状相比，合金的组织得到显著的改善，达到了工程应用晶粒大小。

But from currently circumstance to see, with international top the management more successful archduke department compare, many local business enterprises even the listed company still keeps existing many problems in the aspects of survive management.

但从目前情况来看，与国际上经营比较成功的大公司相比，国内许多企业甚至上市公司在存活管理方面仍然存在许多问题。

A dozen other cities have buildings more inspired architecturally than any built in New York City in the past twenty years.

有十多座其他城市都已经有了一些在建筑艺术上很富有创造性的建筑物，而纽约最近二十年来所造的任何一幢建筑物都不能与之相比。

COMPARED with the argy-bargy over health-care reform, this summer's public conversation about controlling carbon emissions has been a model of restraint.

与医改的争吵抬杠相比，今年夏天公众对控制。。。的谈话在可谓是尽显涵养之风范。

Then, the sequence voltages of the slack bus is replaced, and finding the positive sequence power flow several times until convergence comes off. Compared with the three-phase Newton-Raphson method, the Jacobian matrix with the proposed algorithm is of much lower order. The computation of finding the negative sequence component from the coupling power is only division arithmetic.

本文算法中修正方程式的雅可比矩阵阶数同单相潮流算法相同，是传统三相潮流算法的1/3，而通过耦合功率求解负序分量的计算，仅仅是简单的除法运算，计算量远远小于高阶矩阵的处理，因而总体上，与传统方法相比，大大降低了计算量。

Compared to exist detection methods, the arithmetic's operation is simpler, and need not complex coordinate change, which are more practical.

与现有检测方法相比，该算法具有运算量小，不需进行复杂的坐标变换等特点，具有很大的工程实用性。

July 11, 2002 -- New weapons in the AIDS armamentarium are less likely to cause lipid abnormalities than other antiretroviral medications, according to a presentation at the XIV International AIDS conference in Barcelona, Spain, and a report in the July 10 issue of JAMA .

根据在西班牙巴塞隆纳举行的第14届国际爱滋病会议上公布的一项研究，以及7月10日版《美国医学会》杂志中的一篇报导，与其他抗逆转录病毒药物相比，治疗爱滋病的新型药物引起脂质异常的可能性更小。

Market reality is, brand advertising business is being done on search engine still is too little, what comprise with broad medium and small businesses is alleged " ant army group " photograph comparing, baidu has not gotten more " elephant stage business " favour.

改变 市场现实是，在搜索引擎上做品牌广告的企业还是太少，与广大中小企业组成的所谓"蚂蚁军团"相比，百度还没有受到更多的"大象级企业"的青睐。

The basic concept of FOP can be summarized as to further optimize effective prescription according to the standard of curative effects and with the aid of modern science and technology and theories of traditional Chinese medicine.

其基本内涵可概括为：以确有疗效的中药复方为研究对象，以现代科学技术和传统中医药理论为技术支持，以该复方所治病证的药效响应为评价标准，以优化重组疗效更优的新复方为研究目的。

Ever since our world has been a world, native forests have been indiscriminately exploited by man.

自从我们的世界一直是世界原生森林被任意剥削人。
