From the sea ice motion data extracted from the MODIS and AVHRR images, it is found that the sea ice motion in the Bohai Sea is effected not only by prevailing winds but also by topographic steering, ocean currents and internal ice stresses. The extracted sea ice drift is similar to observed ice drift, and can clearly show the sea ice drift in the Marginal Ice Zone especially. It can compensate for the limitation of the local or single station observation.

Firstly, three popular ionosphere models (Klobuchar model, IRI and JPL GIM) were compared with grid TEC. Then CNC TEC Map using Kriging method with constant drift, linear drift and quadratic drift were compared with each other. Then TEC map derived from nearest neighbor method, polynomial regression method (order=5) and Kriging method with different temporal resolution of 5 minutes, 30 minutes and 120 minutes were compared.

The main factors determined IMS resolutions are the initial ion gate pulse width and diffusion in the drift tube. We conclude the homogeneity of the electric field in the drift tube through analyzing the relation between resolution and ion gate pulse width and drift tube temperature. It is still concluded that inhomogeneity of the electric field has much influence on IMS resolution, which is generally ignored previously.

IMS分辨率最主要的决定因素是离子门脉冲的开门时间和离子在迁移管内的扩散效应，根据在不同离子门开门时间和不同温度下所作的分辨率关系曲线，我们推断出了迁移管内电场的均匀情况，并且得出在一般的IMS工作条件下，迁移管内电场的不均匀对分辨率也有很大的影响，这在以前人们讨论IMS的分辨率时通常被忽略，并没有引起足够的重视。

As walk-off angle and acceptance angle of beam limit the conversion efficiency and the tunable wavelength range of difference frequency generation, research include effective nonlinear coefficient, walk-off angle and acceptance angle as functions of wavelength, the relationship between conversion efficiency and acceptance angle, and the impact of crystals length on the process of frequency conversion.

Based on force diagram an analytical expression between some factors and splaying angle of the bar is brought forward, pointing out that splaying angle of the bar should be 2 3 degrees, and slitting angle should be 30 degrees approximately, outboard slant angle on the slitting groove should be 45 50 degrees and bite angle should be 7 8 degrees.

为稳定小规格带肋钢筋的三线切分轧制，对涉及棒材张开角的切分孔孔型诸角度进行了分析，通过对轧件受力状态的讨论，提出了诸因素与棒材张开角之间的解析式，指出满足三线切分稳定轧制时的棒材张开角应为 2°～ 3°，相应的孔型切分角为 30°左右，孔型外侧壁倾角应在 4 5°～ 5 0°之间，咬入角可控制在 7°～ 8°之间等。

Under the vertical load, the strength of rock mass is higher when there is only one group of joint and the dip angle is less than 20 or higher than 80; When dip angle is between 20 to 80, the strength of rock mass is much lower, it is smallest when dip angle is about 50, and it is lower when this kind of dip angle is in combination with other angle.

7在铅直向荷载作用下，岩体中只存在一组倾角小于20°或者大于80°时，岩体的强度相对较高；当岩体中存在一组节理的倾角在20°～80°间时，岩体的强度值很小，而且在与其他倾角的节理组合时，岩体的的强度值变化不太大，特别是当节理倾角为50°左右的时候，岩体的强度相对最低。
