一、前 扭少曰螺旋埋弧焊钢管的制作过程是，由钢管厂购进的钢卷送人制管机生产线，按工艺技术要求切头、切尾和切边后送人成型机组成型、焊接，制成钢管。

With respect to the above-cited issues an experimental study was conducted of the gas-solid dual-phase flow characteristics of the Tangential firing system and the reverse tangenfial firing system with the help of PDA system.

针对切向燃烧锅炉燃用劣质煤时的稳燃及水冷壁高温腐蚀问题，采用PDA测量系统，对四角切圆锅炉中一、二次风同心反切和同心同向燃烧方式进行了气固两相流动特性的实验研究。

Finally, the forming and localization course of shear band of tungsten alloy material have been analyzed. The influence of thermodynamics parameter of density, static yield stress, specific heat coefficient and heat conducted coefficient on shear-localized of tungsten alloy has been contrastively and individually analyzed through changing magnitude of each parameter. The result has shown that static yield stress and specific heat coefficient have bigger influence on the shear-localized of tungsten alloy.

最后对钨合金材料中的剪切带的形成和局部化过程进行了分析，并且在分别改变密度、静态屈服应力、比热容及热导率等热力学参数下，对比分析了它们对钨合金剪切局部化的影响程度，结果表明改变静态屈服应力和比热容对钨合金剪切局部化的影响较大。

The optimum lathe settings for incisor bar and for smooth roller bar were quite different, which indicate that the lathe settings have to be adjusted after changing bar from one to another.

柔化辊的最佳旋切设置为：旋刀倾角90.5°，垂直间隙9.84mm，水平间隙2.79mm；光滑压辊的最佳旋切设置为：旋切倾角88.5°，垂直间隙11.75mm，水平间隙2.54mm。

The paper presented a new way for the sideway fine feed of cutting piston ring groove : After cutting the groove bottom,the cutting tool make a sideway fine feed of cutting along the groove width to restore the groove width to correct dimension and the cutting tool life being prolonged.

提出了一种精切活塞环槽时刀具侧向微进给方案：在切槽刀具切到槽底后，再作一个微量的侧向进给运动，对环槽的一侧进行微量切削，使加工后的环槽宽度恢复到理想尺寸，达到延长刀具寿命的目的。

Do not handle chips by hand and do not use chip hooks to break long curled chips.

禁止用手处理切屑以及用切屑钩子弄断长而卷曲的切屑。

By comparing the pictures captured during cutting, we can see that chip breaker plays its role most in the planing cutting direction. The cut fibers are break by chip break before hand, so that digging out reduces.

从切削过程中采集的图片及切屑状态，并对照试验一的图片，可以看出在纵向切削时断屑器所起的作用最为明显，切屑在断屑器的作用下被提前折断，加工试件表面的挖切现象也比试验一中有所减少。

This equipment consists of a sample holder, a shearing arm with a chisel-shaped tool at the end, and an instrument for measuring the shear strength of the bond.

该设备包括：测试样品装载装置，剪切臂，剪切臂末端需有一剪切用刀头，以及可以测量剪切力度的读数装置。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.

气候直方图是将所收集的降水量测定值，分为几个相等的区间作为横轴，并将各区间内所测定值依所出现的次数累积而成的面积，用柱子排起来的图形，也叫做柱状图。
