Comparing with Galaxy, M31 has much lower gas and SFR profiles, but their total dynamic: mass are comparable. That means M31 needs faster star formation rate and infall rate (namely shorter infall time scale) in order to consume more gas . However, the low nietallicity and flat abundance gradient require lower star formation efficiency, and few metal poor stars means the infall time scale can not be very short.

与银河系相比，M31有着较低的气体轮廓及SFR轮廓，但其动力学总质量与银河系相当，这便要求有较大的SFR及较快的下落速度来消耗更多的气体；然而，较低的金属丰度及丰度梯度意味着SFE不能过高，贫金属星很少又暗示着下落时标不能很短。

The results provide a solution to the problems of how to control the impact velocity and how to make the impact velocity for each layer approximately equal and close to the inferior limit in the explosive welding of multilayer metal plates.

该文研究结果为控制层间撞去速度，使其达到基本一致，且接近焊接下限提供了解决方法。

The results of research show that the impurity of infusibility and metal ion has been removed after the leaching of calcium carbide residue, and the transform rate of hydrated lime up to about 88%.

研究表明，电石渣经浸取后不溶性杂质与金属离子杂质都被除去，氢氧化钙转化率为88%左右。

It is proposed that the runner location should be first to be selected to ensure molten metal filling along the die wall in order to reduce melt flow resistance and then ingate should be located in the heavy section of the workpiece to which the melt would be filled at the beginning. As a result, the applied pressure could be transmitted fluently to avoid shrinkage cavity and to ensure castings quality.

指出浇道位置的选择首先要保证金属液沿着型壁顺序充填，以减少金属液的流动阻力；内浇道应使液态金属从制件厚壁处开始充填，以利压力的传递，消除缩孔，保证制件的质量。

Especially, it seemed to be difficult to achieve such new bone ingrowth on the surface of inert metal material.

但它们仍然存在一些问题：如应力遮挡导致的骨吸收，表面的磨损颗粒，局部的应力不均匀，金属腐蚀而产生的金属离子毒性。

Most of this inestigation has inoled bone ingrowth into porous metal surfaces.

这些研究中多数是有关多孔金属表面骨长入的研究。

An efficient protective material for metal relics was studied in the paper. Volatile rust proofing sieve, vapor inhabitability of mass loss and closed space volatile weight-loss methods were adopted to study many monocomponent volatiles corrosion inhibitors . The best VCI was chosen from them. By mixing, the two composite VCIs were made for iron and copper.
