The 11 kinds of surface crack features of round cast billet formed by high casting temperature, mould flux lubricating film un-uniform at billet shell, unstale casting speed, tundish nozzle eccentric, alloy steel cast billet cooling and reheating speed overhigh, deleterious elements Pb,Sn,As,Sb and Bi residual content in steel over standard requirements and mould copper tube shifting,...

叙述了浇铸温度高，保护渣润滑膜不均匀，铸坯拉速不稳定，二冷水不均匀，中间包水口不对中，合金钢铸坯冷却和再加热速度过快及钢中五害元素超标和结晶器铜管偏移等致使圆铸坯表面形成的 11种裂纹的特征及其预防措施。

A systemic research on the birefringence of side-hole fiber is presented. The research results show that the birefringence of circular-core side-hole fiber relies mainly on stress birefringence, its fast axis is parallel to the link line of the two holes, and its intrinsic birefringence increases exponentially with the angle and ellipticity of side holes.

本论文的主要研究结果和创新在于： 1、对边孔光纤的双折射特性进行了系统研究，提出圆芯型边孔光纤以应力双折射为主，两边孔连线方向为其快轴方向，其双折射大小与边孔张角和边孔椭圆度成指数关系。

EPLF was produced by pricking in the left round window membrane of the guinea pig and by suctioning 2～4μl of perilymph fluid with a fine needle,than,the animals were killed on 1,2,4,7,14 and 28 days later,respectively.Morphologic changes of the cochlea were observed under a light and scanning electronic microscope.

用微型注射器刺破左耳圆窗膜，并抽出2～4μl外淋巴液造成EPLF，分别于造瘘后1、2、4、7、14和28天处死，光镜和电镜下观察内耳形态变化。

By Visual Basic 6.0 program, taken the distance between hole 200mm and buried depth 120～150mm as the optimization goal, the most optimum parameters range of the mechanism was obtained as follows: the initial angle between planet frame and the line formed from spraying-fertilizer needle-tip and planet wheel axle was -45°～-40°, the initial angular displacement of planet frame was 40°～50°, the distance between spraying-fertilizer needle-tip and the planetary gear axle center was 280～300mm, simultaneously, the semi-major axis of elliptic gear was 29.364mm, the teeth quantity was 23, the ratio of semi-minor axes and semi-major axis was 0.958, the radius of circular gear was 25mm.

对该机构进行运动学分析，建立了数学模型，以穴距200mm和入土深度120～150mm为寻优目标，应用Visual Basic 6.0软件编程得出满足机构运动要求的最优参数范围为：喷肥针尖和行星轮轴连线与行星架的初始夹角-45°～-40°、行星架初始角位移40°～50°、喷肥针尖与行星轮轴心距离280～300mm，此时椭圆齿轮长半轴29.364mm、齿数23、短半轴与长半轴比0.958，正圆齿轮半径25mm。

The results of experimental and theoretical study indicate that the unpolarized light from He-Ne laser is equivalent to circular polarized light.

实验和理论研究的结果都说明由氦氖气体激光器发出的非偏振光是和圆偏振光等效的。

The BMW roundel badge is believed to have been partially derived from the logo of its predecessor company Rapp Motorenwerke, while ultimately taking on the colors and checkers from the arms of Bavaria (fusilly in bend argent and azure).

宝马圆徽章被认为是部分来源于标志其前身公司拉普Motorenwerke ，而最终采取的色彩和跳棋从军火巴伐利亚（ fusilly在弯曲银色和蔚蓝色的）。

Yuande therapy will make you defecate free and relaxed in a short time. You could defecate as usual, even though contracting sphincter. Avoid and reduce the severity of hemorrhoids, rectocele, bleeding phenomenon and incarcerated phenomenon. If constipation, don't be nervous. Practice the Yuande therapy more will cure it.

如用"圆德功法"在短时间内能轻松自如的排便，就是收着括约肌大便也照样的排出，就此避免及减轻了痣疮和脱肛的脱出症状和出血现象，更避免了直肠及痣的嵌顿现象，如大便干爆了也不必着急，多作会功就解决了。

In addition, the effects of the rotational misalignments and relative surface misorientations between two wafers on electrical resistance of bonded wafers were also studied.

另外，也研究晶圆接合的旋转角度差异和两晶片表面角度的差异和电性变化的关系。
