Based on the analysis of the process of free orthogonal metal cutting, the theory of elastic-plastic distortion and temperature field was discussed. Yield rule, intensify rule, fluxion rule, types of contact and diathermanous model of metal cutting were also analyzed detailedly. The FEA model of stress field and temperature field of free orthogonal metal cutting were established by the fundamental idea of FEA. State nonlinear, material nonlinear and geometry nonlinear thermal-stress coupling were analyzed by FEA technology. The separate criterion of chip and dispose of contact types were research emphatically.

本文在直角自由切削过程分析的基础上，讨论了金属切削过程中的弹塑性变形理论和温度场理论，详细分析了屈服准则、强化准则、流动准则、金属切削传热模型、接触类型等问题，并利用有限元的基本思想，建立了直角自由切削应力场和温度场的有限元模型，进行了状态非线性、材料非线性和几何非线性的热力耦合分析，重点研究了切屑分离标准的确定、表面接触类型的处理等问题。

It''s demonstrated that the ductibility of the wrapped bar is between steel bar and pure FRP corresponding to the results of theoretic predict.

结果表明，芯材为金属的包覆筋延伸率介于金属筋和芯材为非金属筋之间，试验结果和理论预测是基本一致的。

Marines are normally armed with C-14 Impaler gauss rifles that fire 8mm metal "spikes" at hypersonic speeds. Basic rounds are designed to provide maximum penetration against all armor types, but a number of specialized rounds exist.

First firing of raw materials are usually basic glaze frit, in the process of production need to add metal oxides, metal ions is also a special color of the enamel glaze color, or as a gel, or suspension-like particles of the dispersion or absorption of light and color, for example, cobalt oxide blue or purple, blue green copper oxide, cobalt oxide copper oxide mixture is significant blue, red cuprous oxide, nickel oxide in the potassium content of the glaze was red, in the sodium yellow glaze of green, if used alone was brown iron oxide, cobalt oxide and manganese dioxide are combined black or dark brown.

通常是先将原料烧成基本釉的熔块，在制作的过程中再加入需要的金属氧化物，也就是以金属离子特具的颜色而使珐琅釉呈色，或成为胶状，或悬浮状的粒子对光线的色散或吸收而呈色，例如氧化钴呈蓝或紫色、氧化铜呈蓝绿色、氧化铜混和氧化钴则显青色、氧化亚铜呈红色、氧化镍在含钾之釉中呈红色、在含钠之釉中呈黄绿色，又如氧化铁单独使用呈褐色，与氧化钴及二氧化锰合用则呈黑色或黑褐色。
