To the problem of unbiasedness of L 1 estimation,basing on uniqueness of solution,Zhou Shijiang proved it according to dual theorem of linear programming; and Wang Zhizhong proved it according to probability statistics theorem by using the method from special to general; also,basing on error distribution theorem and probability statistics theorem,the authors proved it.

对于L1 估计的无偏性问题，周世健基于解法的惟一性，根据线性规划的对偶理论，证明了L1 估计的无偏性[5] ；王志忠根据数理统计理论，采用由特殊情形推广到一般情形的方法，证明了L1 估计的无偏性[6] 。

In this paper,a numerical solution for radial journal bearings with liquid hydro-dynamic lubrication is analysed, numerical expressions for oil fiton pressure, bearing capacity , friction moment,and leakage at the bearing ends are derived,bearing capacity,flow rate, friction moment,and eccentric angle of the load under 14 different temperatures and 14 different load eccentricities are calculated.

采用数值法分析解算液体动压向心滑动轴承，推导了油膜压力、承载力、摩擦力矩和端泄流量等的数值表达形式，计算了14个不同温度点及14种不同偏心率下的承载力、流量、摩擦力矩、载荷偏位角，并通过AUTOCAD绘制了它们之间的影响曲线。认为偏心率及油温对承载力影响很大，设计时应加以限制。

Higher value of mean endomorphy and mean mesomorphy showed male students had much fat and more developed skeletal and muscle systems than female students. Compared with other regions, college students in Qingdao area were fatter,and skeletal and muscle systems were poorly developed. The comparison of the mean ectomorphy and the body length/body weight showed that the male was close to the female on the body linearity.

内因子和中因子平均值偏高反映出青岛高校男性大学生在肥胖程度、肌肉和骨骼发达程度上较女性偏大，而外因子平均值和HWR值的比较显示出男女大学生身体线性度相近；男生内因子平均离散度和HWR离散度较女生偏高，SAD为1.65±0.51，表明男女大学生体型具有一定的差异。

The somatotypes developed from Mesomorph-Ectomorphy to Ectomorphic Mesomorphy in male; however, it was from Ectomorphic Mesomorphy, Central, Balanced Ectomorphy, Balanced Endomorphy to Mesomorphic Endomorphy in female. Conclusion: The somatotypes of Tibetan adolescents in Naqu are slim with little fat; musculo-skeletal system is not well developed.

结果：那曲地区藏族青少年男性的体型为中胚层－外胚层型均衡型(2.40-3.52-3.59)，女性为中间型(3.73-3.23-3.21)；男性由中胚层－外胚层均衡型发展为向偏外胚层的中胚层型，女性由偏外胚层的中胚层型经历中间型、均衡的外胚层型、均衡的内胚层型发展为偏中胚层的内胚层型。

Comparing with FWM without dressing fields,the strength of the singly-dressing FWM signal is suppressed when the modulation-field is linear or elliptically polarized.

与非缀饰四波混频信号的强度相比，单缀饰光作用下的四波混频信号的强度在偏振调制光为线偏振及椭圆偏振的情况下受到了不同程度的抑制。

The influence of DC bias current from Ib = 0mA to Ib = 5mA on the GMI effect in the glass-covered wires annealed by 70mA DC current is investigated.

随着偏置电流的增加，非对称性逐渐增强，直到偏置电流为2mA；当偏置电流继续增大时，非对称性逐渐减弱。

The measurement method of the polarization grade for the source and depolarization and the concept of the polarization error for the illuminance meter are described.

介绍了光源偏振度的测量和消偏振的方法以及照度计偏振误差的概念。

The measurement method of the polarization grade for the source and de polarization and the concept of the polarization error for the illuminance meter are described.

文摘：介绍了光源偏振度的测量和消偏振的方法以及照度计偏振误差的概念。你知道它的英文吗？

Bring about air temperature of plain change area the reason of unusual change is very much, the sea expresses Pacific Ocean of equatorial middle east temperature is unusual on the high side the on the high side that can cause this area air temperature northing of high pressure of; South Asia and intertropical Pacific Ocean sea lifts lukewarmly on the west , through the influence subtropic circle system all can cause on the high side of air temperature of plain change area .

导致川渝地区气温异常变化的原因很多，赤道中东太平洋海表温度异常偏高会引起该地区气温的偏高；南亚高压北进以及热带西太平洋海温的升高，通过影响副热带环流系统均会造成川渝地区气温偏高。

Since Leptokurtosis, skewness and fat-tail are always used to depict market risk, this paper introduces the improved Laplace distribution to risk management of stock portfolio. Empirical results show, improved Laplace distribution and asymmetric Laplace distribution are similar for estimating Leptokurtosis, while improved Laplace distribution is better for estimating skewness.In order to analyze the correlation between return distribution and volatility, the thesis uses ARCH-M Models to simulate the return series of China's Stock Market and developed markets ao as to discover the relation between investment return and time-varying risk.

对尖峰、厚尾、偏态的刻画有助于正确估计市场风险，本文将改进型Laplace分布引入到股票组合的风险管理中，实证结果发现，改进型Laplace分布和非对称Laplace分布对尖峰、厚尾的刻画效果接近；而非对称Laplace分布对负偏性考察不足，改进型Laplace分布的拟合结果能够准确地反映股指收益的负偏态，这也正是改进型Laplace分布相对于传统的非对称Laplace分布的优势所在。
