The mechanical properties and microstructure of the joints joined by the new developed filler metal and TC18 filler metal were compared,the results showed that only the strength of the joint joined by TC18 filler metal was satisfied,while the comprehensive mechanical properties of the joint joined by the developed filler wire were ideal.

对采用研制的焊丝和采用TC18同质焊材钨极氩弧焊焊接TC18钛合金的接头力学性能及微观组织进行了对比研究，结果表明：采用同质焊材焊接TC18钛合金只能保证接头的强度指标，而采用研制的新型焊丝焊接TC18钛合金，可以保证接头具有优良的综合力学性能。

Based on the principle of powder surface modification and the coating process of chemical deposition, the composites of titania/ kaoline were prepared by the hydrolysis of titanium tetrachloride and precipitating on the surface of kaoline.

借助粉体表面改性的原理及液相化学沉积的包覆工艺，以高岭土为核，利用四氯化钛水解在其表面包覆一层纳米二氧化钛制成高岭土复合钛白，并用TEM、XRD等手段进行了表征。

Low-Ti basalt magma was obviously contaminated by continent crust, in a larger extent than high-Ti basalt magma.

低钛玄武岩浆受到陆壳物质的明显混染，高钛玄武岩浆也受到混染，但混染程度弱于低钛玄武岩浆。

Well worth mentioning BE, gold leaf metal alloy and hat color inside the gold deposition and tooth essence color are close, therefore the beautiful effect of the repair body wants to surpass titanium metal alloy and roast a porcelain hat;But because titanium metal specific weight is smaller, the titanium metal alloy roasts the weight of porcelain hat obviously and a little bit lightly, suitable for empress many units of the tooth roast porcelain bridge repair.

值得一提的是，金铂合金与金沉积内冠颜色与牙本质颜色接近，因此修复体的美观效果要优于钛合金烤瓷冠；但由于钛金属本身比重较小，钛合金烤瓷冠的重量明显较轻，适合于后牙的多单位烤瓷桥修复。

In addition to their higher thermal stability, neoalkoxy titanates offer somewhat enhanced final properties compared to monoalkoxy counterparts; according to Monte, the properties obtained with monoalkoxy coupling agents are about 92% of those with neoalkoxy variants.

除了具有高的热稳定性，比单烷氧基钛酸酯提供更高的最终性能。按照 Monte 的说法，单烷氧基钛酸酯获得的性能大约是新烷氧基钛酸酯的92%。

This authors introduce the methods of a statistical and infinite calculus to determine the marginal grade of titanium placer in Panzhihua City,in order to make a complete analysis of reserves of titanium placers there.

简要介绍用统计和曲线积分方法确定攀枝花钛砂矿的边界品位；对传统的地质块段法储量估算进行数学纠正，并对调查区钛砂矿储量进行估算，旨在提出一个钛砂矿储量估算分析流程。

And we can according to GB/T,ASTM, ASM and others standard to produce the titanium and titanium alloy sheet, bar, wire ,standards screws, nut , and so on.

并且可按照用户的要求生产GB/T、ASTM、ASM等标准的钛及钛合金板、棒、丝、标准件等钛产品。

At experimental equilibrium volume, the total energy of CaTiO〓 increased with the displacement of Ti along [001] direction and the lowest energy point is always at zero displacement of Ti. However, with a 10% volume expansion, the displacement of Ti along [001] direction results in a shallow, but well-defined double energy well and ferroelectricity appears.

钛酸钙在实验晶胞体积下，钛离子沿[001]方向的位移不会引起总能量的降低，当体积膨胀10％时，钛离子的位移会引起系统的总能量的降低，在一定的位移时总能量呈现极小值，即出现铁电性。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。

The relationship between communicative competence and grammar teaching should be that of the ends and the means.

交际能力和语法的关系应该是目标与途径的关系。
