Poll shows a very tight raise race in Indiana and senator Obama's comfortable two digit leading in the polls in North Carlina has straight dwindled down to single digit s .

民调显示在印第安纳州另奥巴马放心的两位数优势已被追进，而北卡的民调显示优势已经缩小为一位数了。

Using panel data of listed companies, this paper analyzes it with a quantile regression approach, then draws a conclusion: the share structure and the capability of emerging interior resources effect the capital structure changeably with the different quantiles respectively. That is, for those conditions with low asset-liability ratio, the sign is positive, on the contrary, the sign is negative.

为此本文尝试着将分位数回归理论引入到回归模型中，通过对我国上市公司的相关数据进行分位数回归分析后发现，不同资产负债率水平下，企业股权结构、企业产生内部资源的能力对资本结构的影响效果不同：低负债率水平下，两者均与债务水平正相关；而高负债率水平下，又均与债务水平负相关。

The successive stability constants which are obtained by non-linear least-squares methord fitting Bjerrum formula. In three- system ,the results from Scatchard plots indicate that there exists two strong binding site of Mn and one strong binding site of Zn,there are same results compareing with two -system ,but some more weak binding sites are different from the different addition sequence ,show that there are not common strong binding site of Mn,Zn in HSA or BSA .Strong binding sites have electiveness and unfalteringness ,weak binding sites exists irreversibility.

用非线性最小二乘法拟合Bjerrum方程，计算了同时竞争体系的逐级稳定常数；Scatchard图分析表明，三元体系中，Mn和Zn与血清白蛋白结强合部位数分别为2和1，与二元体系相比，保持不变，弱结合部位数随加入顺序的不同而不同，但都有所增加，竞争结果说明了Mn和Zn与血清白蛋白结合没有共同的强结合部位，强结合部位具有专一性，选择性，而弱结合部位具有不可逆性。

Rough error processing that frequently used to digital filtering was taken as the research object,on the basis of difference method commonly used in the past and profile method of fractile method,a synthesis algorithm-fractile method based on difference method was proposed.The algorithm for processing the rough error data was perfected .The method had been used in a detection system and result is satisfactory.

对数字滤波系统中经常使用的数据处理算法做了综合处理，对于数据采集过程中所得数据做粗差判断处理为主要研究对象，在过去常用的差分法和分位数分布图法的基础上提出了一种综合处理方法-基于差分法的分位数方法，对系统中的粗差数据处理算法做了更完善的探讨，该方法已在实际检测系统中应用，效果显著。

The results showed that sevoflurane was the most prevalent volatility halogenate anesthetics and had the highest concentration at sampling areas. All study hospitals exceeded the exposure limit for halogenate anesthetics (2ppm) recommended by NIOSH (National Institute for Occupational Safety and Health).The median level of N2O at the two medical centers was 1.87 ppm. Although regional hospitals seldom use N2O, its concentration was very high (median 120.85 ppm).

结果显示，Sevoflurane为使用最多之挥发性卤化麻醉剂，环境浓度亦最高，各医院均有高於NIOSH对於单一卤化麻醉剂暴露建议值(2ppm)的情形；医学中心笑气浓度之中位数为1.87 ppm，然区域医院虽极少使用笑气，环境中位数浓度高达120.85 ppm，有管路或开关阀泄漏之可能性。

After pericardiocentesis, the intrapericardial pressure decreased (median value,–5 mm Hg; interquartile range,–5 to 0), whereas right atrial and end-diastolic right and left 9 ventricular pressures, although slightly reduced, remained elevated, with a dip–plateau morphology.

在心包穿刺后，心包内压力下降(中位数为-5mmHg，四分位数间距为-5～0mmHg)，而右房压及左室和右室舒张期末压虽然有轻微下降但仍然较高，形态上表现为倾角-平台状。

As a result, quantile regression method is better than other methods in both measuring systematic risk and nonsystematic risk.

在度量非系统性风险方面，主要应用于度量市场风险，并与利用GARCH模型度量VaR的方法和历史模拟方法进行比较，通过后验测试，结果表明，分位数回归在模拟VaR序列方面更为准确些；而在系统性风险度量方面，无论是根据平均绝对离差指标还是方差指标来看，结果发现利用分位数回归计算的系数要优于普通最小二乘估计和M估计。

Methods According to the oestradiol level on progesterone initiation day, 279 hormone replacement-frozen embryo transfer cycles were grouped into three groups (group 1, percentile 0-25th; group 2, percentile 26th-75th; group 3, percentile 76th-100th).

按照激素替代-冻融胚胎移植患者黄体酮开始注射日血清雌二醇质量浓度的百分位数，将279个周期进行分组（组1百分位数为0～25，组2为26～75，组3为76～100）。

Respondentsreported a median of 2550 deliveries per year (interquartilerange 2000, 4000), with 30% delivered by cesarean delivery(IQR 25.5%, 32.5%) and 5% of cesarean deliveries performed undergeneral anesthesia (IQR 4%, 8%).

受访者报告的中位数为2550次分娩/年（四分位数间距 2000 ， 4000 ），其中30 ％为剖宫产（ IQR 25.5 ％， 32.5 ％），5 ％的剖宫产在全身麻醉下进行（ IQR 4 ％， 8 ％）。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
