Gong-Ti poetry in the rear of Liang Dynasty has close relationship with the evolution in society, the climate of lechery and the passion on literature of Liang Dynasty.

梁朝后期出现的宫体诗，与南朝以来的新变思潮、社会流行的重色风气和梁代的好文之风密不可分。

Based on transformation thermodynamics analysis, the smaller the grain sizes of melt-spun alloys are, the lower the M is. The melt-spinning technology does not change the crystal structure of the alloy. There exist obvious textures with (400) crystal plane preferential oriented crystal structure in the melt-spun alloys with different quenching rates.

Ni-Mn-Ga合金马氏体相变的热力学分析表明：快淬合金晶粒愈细小，M愈低；快淬工艺不改变合金的晶体结构；在不同淬速的快淬合金中有以(400)晶面为择优取向的织构存在。

The results show that this kind of roughening elements can possess a wide range of roughness, and the hydraulic resistance decreases with the increase of space between roughness elements, but reduces slowly to a constant, and that flow enters into the turbulently rough zone when Reynolds number reaches about 3 500, in which the hydraulic resistance decreases with increase of relative submergence degree, reducing slowly to a constant too.

通过水槽试验对Y型加糙体阻力特性进行了深入研究。研究结果表明：其糙率具有一个较大的调整范围，且随着加糙间距的增加水力阻力减小，减小的幅度越来越小，最后基本不变；雷诺数在3 500左右水流进入阻力平方区，进入阻力平方区后，随着相对淹没度的增大水力阻力减小，最后达一定值。

Research shows : laser treatment, the hardening layer from the melting zone, transformation hardening and the heat-affected zone, organizations to small uniform martensite, have a high density of dislocations, which are high hardness and wear resistance of the main reasons.

研究表明：激光处理后的硬化层由熔凝区、相变硬化区和热影响区，组织为细小均匀的马氏体，产生了高的位错密度，这些是硬度和耐磨性高的主要原因。

The key advantages of the Suzuki cross-coupling are the mild reaction conditions and the commercial availability of the diverse boronic acids that are environmentally safer than the other organometallic reagents.

催化剂是suzuki偶联反应当中一个重要的因素，选择合适的催化剂不仅能够使反应条件变得比较温和而且能够提高反应产率，甚至能使原本不能发生的反应变为可能。Suzuki偶联反应的催化剂通常由两部分组成：钯源和配体。
