冲头

Compared to where technology in espresso is going today - individual group-cap boilers for each group, dual boiler, dual PID, heat exchanger pre-heating the brew boiler water and mix-valve fine tuning individual on the fly grouphead temperature controls - the heat exchange boiler/brew system is possibly at the limit of its capabilities and risks being left behind by these newer technologies.

对比今天意式浓缩咖啡机技术的发展-独立冲泡锅炉系统对于每个冲煮头，双锅炉，双锅炉PID，热交换冲煮之前的预热水和混合阀微调在不同的冲煮头上进行温度控制-热交换锅炉/冲煮系统是在处理他们能力受到限制或者是减低风险的时候留下了这个继续解决的新技术。

Hexagonal bolts are usually formed with cold heading. The process is classified as open-die forging and therefore its die design is less complicated. The mushroom-like head has to be sheared into hexagonal shape and the amount of the scrap is somehow significant especially for heading with short bolts or high alloy material. There is an increasing demand in increasing the gross profit by increasing the yield of workpiece material.

六角螺栓头端通常以冷间顶铁成形製程来製造，由於冷间顶铁属於开模锻造，模具设计较容易，但需以剪缘模再对蕈状头端冲剪成为六角头，此剪缘后的废料量不容忽视，尤其对於长度较小的螺栓，或其它应用於紧扣件的高级合金而言，藉由减少废料以提高產品毛利的需求日益迫切。

The fractal values of the gully's alcoves have close relation to the orientations of gullies and the poleward facing gullies have higher fractal values than those of equatorward facing gullies.

冲沟沟头的分维值大小分布与冲沟的方位关系密切，面向极地的冲沟分维值较大，面向赤道的冲沟分维值较小。

In this paper,the fractal theory was used to study the gully's alcoves in different orientations of nine craters at the mid-latitudes in the southern hemisphere of Mars.

采用分形理论对火星南半球中纬度9个陨击坑壁内不同方位发育的冲沟沟头形态进行了研究，结果表明沟头的分维值与冲沟发育程度呈显著的正相关关系。

In this paper, the fractal theory was used to study the gully's alcoves in different orientations of nine craters at the mid-latitudes in the southern hemisphere of Mars. The results suggest significant positive correlation between the fractal characteristics of the gullies and the maturity of their development.

You will follow the dive as you swing back under the glider. If you release the brakes when the leading edge is pointing up, glider can be attack so fast and u can get into trouble..NEVER RELEASE THE BRAKES WHEN THE GLIDER IS BEHIND YOU! When the leading edge is pointing to either side, or not entirely straight down, you're also in trouble. The glider will easily develop cravattes, and enter cravatted spirals

如果伞的前缘指向天空的时候，你松开了沙查，这时候你的麻烦大了，伞会非常厉害的前冲，无论是伞是倾斜的还是正正的向前冲，后果可能是包饺子了，或者是卷夹，卷夹螺旋；所以记住：决不要在伞头处于你后面的时候松开刹车！

As the smoke that goes up into heaven from some city that is being beleaguered on an island far out at sea- all day long do men sally from the city and fight their hardest, and at the going down of the sun the line of beacon-fires blazes forth, flaring high for those that dwell near them to behold, if so be that they may come with their ships and succour them- even so did the light flare from the head of Achilles, as he stood by the trench, going beyond the wall- but he aid not join the Achaeans for he heeded the charge which his mother laid upon him.

仿佛烟火腾升，冲指气空，远处海岛上的一座城堡，受到敌人的围攻，护城的人们在墙上奋勇抵抗，苦战终日，及至太阳西沉，点起一堆堆报警的柴火，呼呼地升腾，告急于邻近岛屿上的人们，企盼他们的营救，驾着海船赶来，打退进攻的敌人――就像这样，阿基琉斯头上烈焰熊熊，冲指明亮的气空。他从墙边大步扑进，站在壕沟边沿，牢记母亲的命嘱，不曾介入阿开亚人的营伍。

In this paper the forming process in the multi-ram forging process of high-pressure tee joint used in power industry and petroleum chemistry industry is introduced.

介绍了采用多向模锻锻制动力工业和石化工业用高压三通的工艺过程，通过FEM模拟总结出高压三通的基本成形规律，并揭示了高压三通多向模锻过程中水平冲头向上翘曲现象及其产生原因，为类似锻件的多向模锻工艺的设计提供了有益的借鉴。

Considering the problems of spurgear precise plastic forming, such as high deformation resistance, poor flowability and especial hardness to fill cant of gear, technological plan was developed based on precise plastic forming technique, successive control principle and consecutive local deformation theory. Moreover, structures of the rolling preform die and the die with up and down wellrounded forcer for stamping-extrusion and bulge-extrusion combining forming were designed too.

因此本文的主要研究内容和结果如下：本文以某种直齿轮：模数m＝2，齿数z＝20，压力角α＝200，变位系数x＝0为对象，针对直齿轮精密塑性成形变形抗力大，流动性差，特别是成形中齿轮角隅部分更加难以充满问题，基于精密塑性成形技术、逐次控制原理以及连续局部变形原理提出了&直齿轮滚轧制坯－镦挤、胀挤复合精成形&的工艺方案，设计了滚轧制坯的模具结构和上下冲头带圆角的镦挤、胀挤复合精成形的模具结构。

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。
