In this case, because the ink layer with a thick, large, and the business card printing and membership card-making machine in water supply axial is uniform, then the plates of the left and right ends, paper outside, there are no ink and water, and there is no paper a blank portion of water as a result of excessive water into it to the left and right ends of the paper, causing the business card printing and membership card making pictures and texts, students'overloaded monlchamus imvestigation emulsibility.

差于这种环境，由于不朱层较薄，供火度较不小，且制卡和会员卡制息机在轴向是平均供火的，那么在印版的把握两头、纸弛以内的地区，既操纵油不朱和火乳化，也操纵纸弛的空缺局部汲取火分，甘休不适度的火分不离窜出到纸弛的把握两头，导致制卡和会员卡制息图文乳化过重，不朱色变浅。

The paper analyzes the shortage of traditional roadway measuring wind method,and by theoritical calculation of measurement,the wind amount is tested,and the roadway fixed central point method of wind measurement and the roadway s average wind velocity fixed-point method of wind measurement are proposed,and which solve the problem of low wind velocity and low credibility well.

分析传统井巷测风方法的不足，并通过风量测定的理论计算和对现场风量进行实际验证，提出了井巷中心点定点测风法和井巷平均风速点定点测风法，较好地解决了当前测定风速慢、可靠性差的问题。

"It's because when they fly half their cargo space is empty," says an air freight cargo staff with the Shanghai branch of Cathay Pacific.

"因为他们的飞机在空中飞的时候，有一半的货仓是空的。"国泰航空公司上海货运部一名工作人员这样说。"货运业最重要的是载运率。空飞机怎么赚钱？"他表示国泰航空去年的货邮平均载运率为67％，新加坡航空为63.6％，大韩航空为74％，而国货航和中货航则只有54.5％和53.35％。十多个百分点的差距，就是盈利和亏损的分水岭。以中货航65.97％的收支平衡载运率来算，中货航去年77万吨货邮的载运量，距离收支平衡共差上10多万吨货物。

The frequency fluctuation of the stabilized laser is held within 5.6 MHz and better than 160 MHz of the free-running laser. The root of Allan variance of error signals reaches a minimum of 1.66×10 -11 when averaging time is 64 s, well within the precision needed for application.

稳定后的激光频率波动小于5.6MHz，相对于自由运转时的160MHz有了很大提高，而误差信号的Allan方差均方根在平均积分时间为64s时达到最小值1.66×10-11。

Another study, from, Hendrix College in Conway, Ark., found that poor sleep patterns were linked to poorer academic performance and a decline in grade-point average during the transition from high school to college.

另外一项研究来自阿肯色州康威市的亨德里克斯学院。该研究发现：不健康的睡眠模式跟较差的学习成绩相关，并且会导致从高中到大学过度期间的平均分数下降。

This difference is revealed in research conducted by Mikolaj Jan Piskorski, a professor at Harvard Business School, and one of his MBA students, Bill Heil. They surveyed just over 300,000 Twitter users in May 2009 and found that more than half of them tweeted less than once every 74 days. They also discovered that the most prolific 10% of twitterers accounted for 90% of all tweets.

这一差别是由哈佛商学院的Mikolaj Jan Piskorski教授和他一名MBA学生Bill Heil共同发现的。2009年5月，他们考察了30多万推特网用户，发现他们之中有一半以上平均每74天发言不超过一条，同时，他们发现发言最积极的10%的用户所发布的内容占据推特网全部内容的90%。

The growth of functions in these spaces depends on a weighted function ρ. We investigate the relation between growth and boundary values of the functions, and prove that a function or its radial derivative is in one of the spaces if and only if the p'integral average of the difference of its boundary value function is integrable or bounded.

研究这些函数空间中函数的增长性与边界值的关系，得到了函数或其径向导数属于相应空间的充分必要条件是其边界值差分的p次积分平均应具备一定的可积性或有界性。

Firstly, nonlinear diffusion filter was used to wipe of noise efficiently and kept the edge information of the image. Secondly, gradient calculation of pixel diagonal direction was considered in the calculation of neighborhood gradient amplitude which further repressed the impact of noise. Thirdly, using average interclass variance, the self-adaptively double thresholds for different images were calculated.

首先采用非线性扩散滤波减少了图像噪声，同时保持图像的边缘信息；在邻域梯度幅值计算中，考虑像素对角线方向的梯度，进一步抑制了噪声的影响；最后采用平均方差阈值法选取阈值，从而提高了对不同图像的自适应性。

The metrics include patch density, largest patch index, edge density, area-weighted shape index distribution, area- weighted fractal index distribution, mean Euclidean nearest neighbor distance dlstributlon,standard deviation of Euclidean nearest neighbor distance distribution, coefficients of variation of Euclidean nearest neighbor distance distribution, contagion, interspersion and juxtaposition index, cohesion, Shannon's diversity index and Simpson's diversity index.

根据生态区划计算描述中国陆地景观结构的13种景观结构指数，包括斑块密度、最大斑块指数、边界密度、面积加权斑块形状指数、面积加权斑块分维度、平均最近斑块距离、最近斑块距离的标准差、最近斑块距离的相异系数、蔓延度、分布邻接指数、结合度、香农多样性指数、辛普森多样性指数。
