本文采用X射线极密度和取向分布函数方法，证明含Mo Hi-B钢采用1310℃低温铸坯加热时，其热轧板表层织构特征与不含Mo并在1380℃高温铸坯加热时相似，为典型的剪切形变织构，两者的热轧板与脱碳板表层织构特征也极为相似，而含Mo Hi-B钢在1380℃铸坯加热时却没有以上这些相似性。

本课题所论述的PP瓶的拉伸吹塑成型是采用二步法，即成型好的瓶坯先预热，后用拉伸杆拉伸型坯并通入压缩空气吹胀型坯使之贴紧模具型腔，把模腔的形状与尺寸赋予制品，然后冷却最后脱模。

In order to increase the rolling capability of three-high cogging mill,the forging plant of Laigang reforms the traditional cogging process,joining the six angle-square pass with box pass well and designing the six angle pass with heavy elongation to realize conjugate rolling,thus realizing the heavy reduction,heavy elongation for cogging rolling and single end product outing and self nip,improving the rolling rhythm.

为提高三辊开坯轧机的轧制能力，莱钢锻压厂对传统的开坯工艺进行改造，将六角—方孔型与箱形孔良好衔接，并设计了能够共轭轧制的大延伸六角孔，从而实现了开坯轧制大压下、大延伸，以及成品单出与自动咬入，提高了轧制节奏。

In comparison with bugle shaped nozzle, bifurcated nozzle downward jet angle 45°, cow-nose nozzle and three-hole nozzle, in all, the last two are better than the former and bifurcated nozzle downward jet angle 45 is better than bugle shaped nozzle; Cow-nose nozzle is helpful for guaranteeing the product's quality, in order to protect jet flow from eroding the strand at narrow face, gain uniform temperature distribution at cross section and decrease heat flux, adding the block's width to 100 mm. Three-hole nozzle is advantageous to increase flux and casting speed, but should avoid weak shell thickness in the center broad. In the real production, setting the SEN's immersed depth or plugging the hole at the bottom can adjust the flow and temperature distribution in the mold.

对比喇叭形水口，双侧孔水口(45°)，牛鼻子水口和三孔水口，总的说来后两者优于前两者；而双侧孔水口(45°)又优于喇叭形水口；牛鼻子水口和三孔水口比较各有特点，前者对保证铸坯质量有利，为防止流股对窄面的冲击，增加挡块宽度到100 mm，可使结晶器横截面上温度分布更加均匀，降低窄面热负荷；后者对增加流量，提高拉速非常有利，但要防止中孔射流过强导致铸坯中心坯壳变薄，在实际生产中可通过控制水口浸入深度或塞住浸入式水口的底孔来调节结晶器中的流动与温度分布状态。

The different friction coefficient between tube and die is one of the important influences in tube hydroforming. Reduce the friction as possible, it can not only benefit to tube forming, but also reduce axial force effectively.

不同的管坯和模具之间的摩擦系数也是影响管坯成形的重要影响因素之一，要尽量减少摩擦，不仅有利于管坯的成形，还能有效地减小轴向力。

The differences of the micro structure and properities of the bulk sinters, between the fabrication methed of powder metallurgy and reactive synthesis for silver tin oxide composite, are studied in prensent thesis. With the increase of the tin oxide content in silver matix, the electric conductivity of the composite tended to decreace. While in the same tin oxide content, the electric conductivty of the composite fabricated by reactive synthesisis better than that by powder metallurgy. One of the reasons is that the regular net structure existing in former composite.

研究了两种方法即粉末冶金法和反应合成法制备的银氧化锡复合材料烧结坯在组织上的区别和性能上的差异，两种方法制备的银氧化锡复合材料，随着氧化锡含量的升高，材料导电性均呈下降趋势，而相同成分的材料，反应合成法制备的银氧化锡复合材料的烧结坯的导电性要优于粉末冶金法，有规则的网络状组织结构是反应合成法制备的烧结坯导电性好的原因之一。
