But the volume fraction of particles in composite fabricated by prefabricate method was finite.

但是预制件法制备的复合材料的颗粒体积分数有限，无旋涡机械搅拌法的制备温度高，故这两种方法均不适合制备体积分数高（大于 20％）、颗粒尺寸小的复合材料而利用半固态机械搅拌法，能够将颗粒尺寸为3.5μm；体积分数为40％的SiC颗粒加入到金属Al中，但是当颗粒体积分数大于30％时，机械搅拌方式不能将颗粒均匀地分散在基体金属中。

Barrel is the key part of artillery. In shot process, propellent gas of high pressure and high temperature flows in the tube at a high rate of speed, which brings an upheaval to the temperature field of the composite barrel. As to the composite barrel with metal inner, its poor thermal conductivity is more likely to cause uneven temperature distribution and bigger temperature gradient, to produce improper deformation and to make the work temperature of metal inner rise, all of which will affect the life span of barrel.

身管是火炮的关键部件，在火炮发射过程中，高温、高压的火药燃气在身管内成脉冲式高速流动，使身管受到急剧的加热，引起身管壁内的温度急剧变化，而对于带金属内衬复合材料身管，由于复合材料导热性能较差，更容易引起非均匀温度分布以及较大的温度梯度，产生不合适的变形，也会使身管的金属内衬的工作温度升高，从而使得身管的寿命降低，同时身管的发热会引起其刚度的变化，增大射弹散布。

There is no better product to replace MoM hip prosthesis.

目前无更好的产品来替代金属对金属髋关节假体。

Using the Updated Lagrange finite element method and the elastic-plastic large deformation finite element formula based on virtual work-rate principle of finite deformation, the author studies in detail the plastic flow rule of MPF, including the influence of the work hardening index, friction, thickness of sheet, material, number and position of the punch.

作者采用逐级更新Lagrange法以及有限变形虚功率增率原理的弹塑性大变形有限元法，详细研究了金属板材多点成形的塑性流动规律，包括加工硬化指数、摩擦系数、板料厚度、材料、冲头个数及位置等对成形的影响，同时探讨了分段成形时的金属流动规律。

Below you can find several examples of Punnet squares in order to provide more insight in how the metallic trait is inherited by combining the relatively new metallic genetics with the more familiar blue genetics.

Turquoise x Turquoise下面你可以找到几个例子Punnet广场，以提供更多的有识之士如何金属特点是继承相结合，相对较新的金属遗传学的较熟悉的蓝色基因。

Ten kinds of metal and three kinds of organic templates, including ethylenediamine, 1,4-butylenediamine and pyrazine were used in the synthesis of metal phosphonate coordination polymers.

在所合成的16种金属有机膦酸盐配位聚合物中，有机配体为2-羟基乙酰基膦酸，用于配位的金属离子共10种，模板剂3种分别为乙二胺(en，1，4-丁二胺，哌嗪。

The challenge was to confine electrons tightly in a 'quantum wire' and bring this wire close enough to an ordinary metal so that the electrons in that metal could 'jump' by quantum tunneling into the wire.

所面临的挑战是在一个'量子线'里紧紧地控制住电子，把这根电线接近普通金属这样一来就可以使金属中的电子以"跳跃"的方式使量子穿梭于电线间。

From the real object contrast of plasma lamp quartz shell and the metal halide lamp ( the Fig.2.), from the Fig.2. We can clearly see that the volume of plasma lamp shell is very smaller. In the plasma lamp sulfur has been filled in and the argon gas is used to stated the lamp.

是等离子灯石英灯球与金属卤化物灯实物对比图，它与金属卤化物灯相比要小得多；从（图2）中还可以清晰可见灯球内具有黄色的硫元素，氩气的作用是启动等离子灯。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。

The cost of moving grain food products was unchanged from May, but year over year are up 8%.

粮食产品的运输费用与5月份相比没有变化，但却比去年同期高8％。
