Based on the analysis of forming characteristics of the complicated vehicle parts and the actual formability of sheet metals, a new method assessing the press forming levels of deep-drawing sheet metal has been advanced.

对汽车复杂冲压件的变形特点和钢板的实际成形能力进行分析，提出了利用平面应变点FLD0对深冲薄钢板冲压级别进行分类的新方法，并将汽车深冲薄钢板分为七个级别。

This article is subject to the diaphragm process and stamping die design, the blanking-punching composite modulus and jumping over two sets of single-mode processes mold design.

摘要本文的课题是膜片弹簧的冲压工艺及模具设计，进行了落料—冲孔复合模及冲槽单工序模两套模具的设计。

The draw ratio is the direct relationship between the draw punch and the blank edge—the greater the distance between the draw punch and the blank edge, the greater the resistance to flow, primarily because of the additional surface area of sheet metal clamped between the die face and the blank holder.

拉伸率直接体现在拉伸冲头和展开平板边缘之间的关系---拉伸冲头和展开平板边缘之间的距离越大，限制流动的阻力越大，主要是因为在压边圈和模具表面间有额外金属板表面被夹紧。试着用不同尺寸和外形的展开平板进行实验。

In terms of defects of the traditional oblique wedge die with several side holes that had position degree at the same product,method of integration with rotating wheel and slant was adopted.

针对传统的斜楔模在同一制件上冲制有位置度要求的几个侧孔时的缺点，采用转动盘与斜面相结合的方式，在同一副模具上同时冲出有位置度要求的4个孔。

Combining the result from source inversions, we propose that the oblique-slipping Baishuihe-Gaochuan rupture and the dip-slipping Bailu-Hanwang rupture were produced in the same time during the largest sub-event with a slip partitioning, and the mechanism of slip partitioning made the two faults ruptured with an oblique slip and a dip slip, but not all the same oblique slip.

结合震源过程反演成果的分析显示，斜滑的白水河—高川破裂段和逆冲型白鹿—汉旺破裂段可能是在汶川地震中最大的一次子事件过程以滑移分解的形式而同时破裂形成的，滑移分解作用使两条断裂以斜滑与逆冲组合的力学性质产生破裂而非相同性质的斜滑破裂。

The diagnostic of DT fuel plasma areal density in the direct-driven implosion experiments on SG-Ⅱ laser facility has been performed by measuring the number of recoil D and T produced by 14MeV neutron′s scattering. The particles of recoil D and T were detected by CR39 solid-state nuclear track detector.

在神光Ⅱ基频光直接驱动内爆实验中，利用CR39径迹探测器测量了DT靶丸释放出的 14MeV中子弹性散射后逃逸出燃料的反冲D核和反冲T核的数量，实现了激光聚变实验中燃料面密度〈ρR〉的诊断。

It is considered that link wear speed on seal surface is proportional to the contacting pressure. The impacting of valve disk on valve seat is the important reason of abrasive wear, and the relative motion of disk is a main reason for errosion wear of pump valve. The cycles per minute is an important factor to influence the valve motion and the impact force.

结果表明，泵阀密封面联接磨损的磨损速度与密封面上的接触比压成正比，泵的冲次是影响阀盘运动规律及对阀座产生冲击的重要因素，泵阀产生磨粒磨损和疲劳磨损的主要原因是泥浆、阀盘和阀座的冲击，冲蚀磨损导致泵阀的刺蚀。

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.

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。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
