The main work of this thesis is to research the sulphate bath, we find that the sulfate system has the advantage of slight acidic choloride electrolyte system and alkaline zincate system. The solution of sulphate system is very simple and easy to maintain and high current efficiency. Furthermore, the technology has the advantage of lower plating cost and broader width of the temperature.

本论文的主要内容是以文献中报道不多的全硫酸盐体系电镀锌镍合金为研究对象，发现全硫酸盐体系结合了上述两种类型的优点，镀液成分比较简单，容易维护，对材料、设备的腐蚀比较小，阴极的电流效率高，而且该工艺具有成本较低和温度范围宽等优点。

In this paper the as-cast microstructure, the rules of phase precipitation, the change of microstructure and minor phase content and the degeneration of aluminide coating after thermal exposure at temperature range from 850℃ to 1100℃ for 1000-3000 hours have been studied in comparison between two kinds of low chromium-high tungsten cast nickel-base superalloys.

本文对比地研究了两种低铬-高钨系列的铸造镍基高温合金的铸态显微组织，在850～1100℃范围内热暴露1000～3000小时后的相析出规律，显微组织和微量相的变化及铝化物涂层的蜕化。

I suspect, in honesty, my initial interest was based on a private image of streams of unsuspecting eastbound motorists in the American plains states plunging over the edge of a sudden 4,000-mile-high cliff running between Central America and the North Pole, but gradually my attention did turn in a more scholarly manner to the scientific import of the drawing and the realization that the Earth consisted of discrete layers, ending in the center with a glowing sphere of iron and nickel, which was as hot as the surface of the Sun, according to the caption, and I remember thinking with real wonder:"How do they know that?"

坦白讲，我怀疑自己最初对那幅画的兴趣仅源于脑海中的一幅画，里边一群意志坚定的人驾车东去，要穿越横亘在中美与北极之间的一道深四千公里的悬崖。但后来开始慢慢的以一种学术眼光来研究这幅插图背后的科学含义。并意识到地球是由分离的层组成，最里边是由铁和镍构成的发红的球心。图片旁边的说明文字解释说，这个球心的温度同太阳表面一样高。我仍记得当初十分好奇的想知道，他们是如何得知这一切的。

In this study, 105 TDFs were in silico mapped in the rice high-density linkage map. Nineteen TDFs were mapped to the quantitative trait loci regions for root growth under water-limited conditions in, at least, two of three rice populations derived from three crosses with the same parent of Azucena (Bala×Azucena, IR64×Azucena and IR1552×Azucena). Four of 19 genes (T37, L16, T17 and T7) were mapped based a RIL population of IR1552×Azucena by southern blot analysis. Five genes encode putative or hypothetical protein. Other 14 genes were similar with known genes in databases including expansin (OsEXP2), late embryogenesis-abundant gene , an SR-related protein essential for spliceosome assembly (SART1), autophagocytosis protein , bHLH protein, fruit-ripening protein similar to ASR, nickel-binding protein 2A, DNA-binding protein, pyruvate dehydrogenase kinase , stomatin-like protein, SR1 induced by sucrose starvation, vacuolar protein sorting protein (VSP33a), gibberellin action negative regulator and retroelement.

根据核苷酸序列将105个基因电子定位到水稻的高密度连锁图谱上，其中19个差异表达基因定位在Bala×Azucena、IR64×Azucena和IR1552×Azucena中至少两个群体共同的与根生长相关的QTLs区间，并用Southern杂交将其中的4个定位到IR1552×Azucena群体遗传连锁图谱相应的位点上。19个基因中的5个编码推断的未知功能蛋白质，其余14个编码已知功能蛋白，分别为膨胀素（Os-EXP2）、胚胎后期丰富蛋白、剪接体安装必需的SR相关蛋白（SART1）、自吞噬蛋白、碱性螺旋-环-螺旋转录因子、与ASR相似的果实成熟蛋白、镍结合蛋白、DNA结合蛋白、丙酮酸脱氢酶激酶、stomatins类蛋白、蔗糖调节蛋白SR1、液泡蛋白分类蛋白（VSP33a）、GA负调节因子、逆转座元件。

It has high saltwater corrosion resistance and better edge retention than austenitic stainless steel. 17-7PH is defined as a chromium-nickel-aluminum precipitation hardening stainless steel, a process that develops hardness at relatively low temperatures, allowing hardening with very little distortion.

它有很高的抗盐水腐蚀性和比奥氏体不锈钢更好的刀锋保持性。17-7PH被定义为经过铬、镍、铝沉淀硬化后的不锈钢，其加工工艺能在相对较低的温度下提高硬度，这是通过对其形状影响很小的淬水过程实现的。

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。
