1·With a product line of tens of categories, we can offer quick copying with precise contraction ratio (up to two thousandth) for mold making.

公司产品品种达几十种，为你的模具制作提供快速的复制，精密的收缩率，产品的收缩率可以达到千分之二。

2·Moving cowl, decreasing interior contraction ratio also can realize the hypersonic sidewall compression inlet's self-starting because of separation bubble on sidewall spilling out.

移动唇口板以减小内收缩比可以实现侧压式进气道自起动，主要是因为侧板分离包被排出进气道。

3·Nevertheless, study on various contraction functional status and left ventricular diastolic function at the time of E/A ratio pseudonormalized phenomena is scarce.

但对不同收缩功能状态及E/A比值假性正常化时的左室舒张功能的研究少见有报道。

4·In the case of heavy load when the advance ratio of propeller is small, the contraction of wake has large effect on the performance of the propeller.

在小进距比的重载情况，螺旋桨尾涡的收缩对螺旋桨的性能影响较大。

5·The casting fluidity, ratio of line contraction, casting stress and heat crack tendency were tested.

分析测定了中铬抗磨铸钢的流动性、缩孔率和铸造应力。
