The spiral angle of graduated circle was rough estimated by measuring the addendum circle diameter and modified on milling machine.

介绍了精确测绘单一斜齿圆柱齿轮齿形参数的简便方法，即测量公法线长度计算基圆齿距从而查表确定模数和压力角；测量齿顶圆直径估算分度圆螺旋角，用分度头在铣床上修正分度圆螺旋角，并进行误差分析。

On the basis of analytic geometry, the projection curve types of intersection lines of cone and cylikder, cone and cone on V plane is hyperbola and cone and sphere is parabola.

基于锥与圆柱、圆锥、圆球正贯时，相贯线V 面投影为双曲线和抛物线，且X 向极值点所在高度只与柱、锥轴线、球心距离锥顶高度和立锥锥顶角有关，而与它们的直径无关，给出了求该极值点的作图方法。

The simulation results show that when light wave propagates along the angular bisector of corner angle in metamaterial volume,the electromagnetic focus effect will not exist in the metamaterial volume,although the permittivity and permeability of metamaterial are very small.

仿真结果表明：即便对于εr和μr都很小且无耗的正多边形异向介质柱，当平面光波沿正多边形顶角角平分线方向传播时，在异向介质柱内不会发生电磁聚焦。标签聚焦特性时域有限差分方法异向介质平面光波 Focus charaters FDTD Metamaterials Plane light wave

He laid the notch of the arrow on the oxhide bowstring, and drew both notch and string to his breast till the arrow-head was near the bow; then when the bow was arched into a half-circle he let fly, and the bow twanged, and the string sang as the arrow flew gladly on over the heads of the throng.

他运气开弓，紧捏着箭的糟口和牛筋做就的弓弦，弦线紧贴着胸口，铁的箭镞碰到了弓杆。他把兵器拉成了一个拱环，借大的弯弓鸣叫呻喊，弦线高歌作响，羽箭顶着锋快的头镞飞射出去，挟着暴怒，呼啸着扑向前面的人群。

［Objective］To explore the effect of continuous physiological osteogenic stress on the bone healing of canine iliopectineal crest.［Method］Ten adult mixed breed dogs without significant individual difference were made transverse fracture at bilateral iliopectineal crest 1.5 cm above the dome of acetabulum,which were fixed with ATMFS or steel plate respectively. The animals were sacrificed and specimens were procured at 2,4,6,8 and 12 weeks after operation.Samples from the fracture gaps were investigated by histology of HE and Masson staining,image pattern analysis of new bone formation.

探讨持续顺应生理力线的压应力对犬骨盆弓状线部骨折愈合的影响［方法］选用10只成年杂家犬，双侧髋臼臼顶上方1.5 cm处横形截骨，分别采用ATMFS(骨盆髋臼三维记忆内固定系统)柱固定器和5孔重建钢板内固定，于术后2、4、6、8、12周处死动物取材，行HE染色、Masson三色法染色组织学检查，图像分析新骨形成积分光密度值，研究不同应力作用模式下的骨盆骨折愈合情况。

At the mean time, for P2 and P3 instrumentation points which located at the depth of 2.5 m below the mid-slope surface and at the depth of 3 m below the slope top respectively, the pressure head remain negative and this indicates both points are still situated at the unsaturated zone in between the soaking line and groundwater table.

在此同时，P2监测点(坡面中点下方2.5 m)及P3监测点(坡顶下方3 m)之压力水头则仍维持负值，此显示两监测点周围区域仍处於浸润线与地下水水位线间之未饱和区。
