The welding deformation and residual stress are decreased evidently.The dimensional stability and service security of the welding structure are increased obviously.The impact absorbing energy of weld is improved by 21% under vibratory weld conditioning. And the effect of mechanical vibration on the impact absorbing energy of weld is greater than that of HAZHAZ are refined distinctly. The fusion area and overheated zone are narrowed. And the dimension of Widmanstaten structure minishes or disappeares.

The result shows that the mechanical strength and the thermal stability of bonded hybrid magnet are improved markedly with addition of ferrite in Nd-Fe-B powder,whereas its magnetic performance is reduced slightly.And the temperature coefficient of coercivity with zero is obtained in hybrid magnet with 87% ferrite and 13% HDDR Nd-Fe-B.Due to the magnetic dipole field between the differe...

实验结果表明：随着铁氧体磁粉的加入，复合磁体的磁性能虽略有降低，但其力学性能及热稳定性均有大幅度改善，特别是在铁氧体含量为87%时，复合磁体内禀矫顽力温度系数为零；不同磁粉间静磁场的存在，使得复合磁体在铁氧体含量低于70%时，其磁性能大于平均值，而大于70%时则小于平均值。

In the range of azimuth angle, the average RCS of in plate terminal is higher than that of in blade terminal.

Using the relative reflection as weighting factor, the weighted mean of the surface albedo over Dunhuang Gobi in typical arid region is calculated and its values are 0.255 ± 0.021. After canceling the interference of the buildings, the mean values of the roughness length averaged with logarithm is 0.0019 ± 0.00071 m. After removing the influence of the oasis, the soil wetness factor computed with data under condition of no precipitation is 0.0045. After removing the influence of the precipitation .the mean values of the soil heat capacity over Dunhuang Gobi in typical ac-id region is 112 × 10 ~6 m~(-3)K~(-1), a bit smaller than the values observed i n HEIFE. But the soil heat diffusivity and conductivity are about one of those observed in HEIFE. The soil water content over Dunhuang Gobi in typical synoptic condition is very little and does not exceed 1% basically.

并且利用相对反射为权重加权平均，计算得到典型干旱区敦煌荒漠戈壁的平均反射率为0.255±0.021；剔除建筑物干扰后，利用对数平均法计算的粗糙度长度平均值为0，0019±0.00071 m；剔除绿洲影响后，用无降水影响的资料确定出土壤湿度影响因子为0.0045；剔除降水影响后，用观测资料计算的敦煌典型干旱区荒漠戈壁的热容量平均值为1.12×10~6m~（－3）K~（－1），比&黑河试验&在戈壁和在其它沙漠观测的有关值略小一些，但热扩散率和热传导率都比&黑河试验&在戈壁观测的值小一倍左右；观测的敦煌戈壁典型天气条件下的土壤含水量非常小，基本上不超过1％。

No offense to O.C., who is a fine player and above-average hitter, but his career on-base percentage is .320, and last season it was a less-than-spectacular .335 OBP — good for 131st…in the American League.

不用怀疑O.C是个好球员而且他的打击率也在全联盟平均值以上，但是他的生涯上垒率只有三成二0 ，在上个球季还少於平均值三成三五，在所有美联球员里排名131。
