The results show that influence of content of kraft fiber on compressure-resilience and tribology properties was inapparent, however the compressure rate and resilient rate were increased when pressure was increased, and friction coefficient was decreased to some extent when pressure and rotate speed were increased.

在相同比压和转速条件下，纸浆纤维含量对纸基摩擦材料动摩擦系数的影响不明显，但随着比压和转速的增加，纸基摩擦材料的摩擦系数降低，其中含有17.5%纸浆纤维的纸基材料在循环制动条件下的摩擦系数最稳定，磨损率最低。

The results show that when the porosity of sample was higher, compressure rate was higher and resilience rate was lower, however resilient rate of sample with higher porosity were increased notably when pressure was increased, and it tended to accord with of sample with lower porosity. The friction coefficient was higher when porosity of paper-based friction material was higher, and the friction coefficient tended to reduce and stabilize when braking pressure was increased. The friction coefficient of sample with high porosity tended to reduce and stabilize in continuous braking cycles.

结果表明：在相同载荷下，随着孔隙率增大，材料的压缩率增加而回弹率降低，随着载荷增加，高孔隙率材料的回弹率先明显增大，而后趋于稳定；在相同比压和转速下，孔隙率越高，材料的摩擦系数越大，随着比压增加，孔隙率高的材料摩擦系数逐渐降低，且不同孔隙率材料的摩擦系数逐渐趋于一致；在连续循环制动时，高孔隙率材料的摩擦系数逐渐降低并趋于稳定。

Adopt the generalized maximum likelihood radio test based on the Neyman-Pearson algorithm, to study two unresolved Rayleigh targets. And deduced the detection statistic which is chi-square random variable, which only need to know the conditional probability density functions of echo's measured amplitude, in-phase and quadrature of monopulse radio, but the signal-to-noise radio and the direction-off-arrival of any signal are unnecessary.

采用基于涅曼-皮尔逊准则的广义似然比检测，对不可分辨的两个瑞利目标进行了研究，推出了服从χ2分布的检验统计量，此方法只需要知道目标回波信号测量幅值的条件概率密度函数、单脉冲和差比值的同相和正交部分，而不需要任一目标信号的信噪比和DOA的先验知识。

We possess at least the testimony of Tacitus (AD 54-119) for the statements that the Founder of the Christian religion, a deadly superstition in the eyes of the Romans, had been put to death by the procurator Pontius Pilate under the reign of Tiberius; that His religion, though suppressed for a time, broke forth again not only throughout Judea where it had originated, but even in Rome, the conflux of all the streams of wickness and shamelessness; furthermore, that Nero had diverted from himself the suspicion of the burning of Rome by charging the Christians with the crime; that these latter were not guilty of arson, though they deserved their fate on account of their universal misanthropy.

我们要拥有至少证词塔西佗（公元54-119 ）为陈述的创始人基督宗教，一种致命迷信在眼里，罗马人，已被置於死亡的，由检察长，祂比拉多下腥风血雨的台比留；他的宗教，虽然压抑，一时间，打破了再次不仅在整个朱迪亚何处，它的来源，但是，即使是在罗马， conflux各溪流的wickness和无耻；另外， Nero的已改由自己的怀疑焚烧罗马收取基督徒与犯罪；这些后者没有犯下纵火，虽然他们无愧自己的命运，就到他们的普遍

Opened in 1955 by distinguished hotelier Conrad Hilton, The Beverly Hilton has combined the excitement and entertainment of Hollywood with the elegance of Beverly Hills for 50 years.

比弗利希尔顿酒店于1955年由著名的酒店经营者 Conrad Hilton 开创，在50年中将好莱坞的激情和娱乐性与比弗利山的高雅融为一体。

To compare the image quality of the three sequences in two groups by One-Way ANOVA and T Test. The qualitative assessment standards include clarity, artifacts, signal uniformity, the conspicuity of enhanced vein and the observable grade of intrahepatic venous branchs. The quantitative assessment standards include SNR and CNR of intrahepatic portal vein and hepatic veins. Furthermore, the anatomy and variations of the intrahepatic portal vein and hepatic veins are statistical analysed.

通过方差分析和T检验分别对A、B组三个序列的图像质量进行比较，评定标准包括清晰度、伪影、信号均匀性、静脉强化程度及肝内静脉分支显示级数等定性指标和肝内门静脉、肝静脉的SNR(Signal-Noise Ratio，信噪比)及CNR(Contrast-Noise Ratio，对比度噪声比)等定量指标。

The results show that: at the spatial level, the water potential of SPAC element in the soil, that in the plant and that in the air gradually descends. SPAC water potential gradients are different among conterminous interfaces of soil, leaf and air are amplified from 1:5:30 to 1:15:90 after watering.

结果表明：在空间水平上，油松林地SPAC各要素水势由土壤到植物再到大气逐步下降，梯度比约为1：5：30；灌水后SPAC相临界面水势差增大，水势梯度比提高至1：15：90。
