论文标题：Ni-Ti合金对Ti基金属陶瓷组织和力学性能的影响

The others include 1 martian meteorite, 1 HED meteorite and 6 L3 ordinary chondrites. These 20 equilibrated ordinary chondrites are classified into chemical groups of H, L and LL, respectively, based on mean Fa content of oli-vine, mean Fs of low - Ca pyroxene and abundance of Fe-Ni metal.

根据橄榄石的平均Fa值、低Ca辉石的平均Fs值和Fe-Ni金属含量将这20块陨石分别划分为H、L和LL等化学群；根据球粒结构、基质重结晶程度和矿物成分对这些陨石进行岩石类型的划分。

The included angle between the crack direction and the laser scanning direction decreases as Ni content in the cladded layers is increased.

具体表现为：随着熔覆铁基合金粉末中Ni含量的增加，裂纹方向与激光扫描方向的夹角减小，直至裂纹消失。

The corrosion characteristics in water, 5% HCl solution and 5% HNO3 solution of the coatings on 45 steel cladded by electrospark deposition with Cr, W, Mo and Ni anode was studied.

对正火45钢基体上的Cr、W、Mo和Ni电极电火花熔涂层在水、5vol%盐酸及硝酸水溶液中的腐蚀行为进行了研究。

The results show that from the interface to surface the microstructure of the cladded coating is composed of plane grains,tiny grains and fine dendritic grains. The two main compositions of Ni and Cr homogeneously distribute in the section.

结果表明，熔覆修复层的显微组织从界面往上依次由平面晶、细晶层和中部细小的树枝晶构成，主要元素Ni和Cr在截面内均匀分布，原有Cr层与熔覆层内的Cr元素呈连续状，构件修复区以外的铬层与基体的结合未受激光熔覆的影响。

Microstructures of Ni-Cr-Ti-Al laser claddings on K418 superalloy.

罗根香，吴国清，黄正等， K418合金激光熔覆Ni-Cr-Ti-Al涂层的组织研究。

To avoid the forming of cracks in iron based laser cladding, the volume fractions of austenite and cemetite in cladding layers were adjusted through adjusting the contents of Ni. The claddings were produced on gray irons without preheating.

采用铁基熔敷材料，在不预热情况下通过调整熔敷金属Ni含量，改变铸铁激光熔敷层内奥氏体相与渗碳体相体积分数，进而抑制熔敷层裂纹的产生。

Fracture model and shear bond strength were not relevant. Conclusions: The shear bond strength between porcelain and electroformed copings are significantly lower than that of Ni-Cr alloy.

结果：金沉积5个处理组的金瓷剪切强度分别为6.99MPa、9.04 SPa、9.80 SPa、12.19 SPa、12.86 SPa，低于Ni-Cr合金26.76 MPa(P＜0.05)；断裂模式与剪切强度之间没有相关性。

The specific surface area of the material prepared at 900℃ by dopping Co or Ni in the position "B" of the La_4BaCu_5O_13＋δ is increased about 10% than that of the material prepared by the traditional method.

BET测试表明，在La_4BaCu_5O_13＋δ A位掺Sr可在一定程度上增大材料的比表面积，而在A位掺Ce 则不利于材料比表面积的提高。900℃在B位掺杂Co、Ni合成的材料的比表面积比传统的方法制备的材料的比表面积提高了近10%。

The XRD spectrum of the material prepared by dopping Co and Ni in the position "B" of the La_4BaCu_5O_13＋δ, indicates that there are still some foreign matter phase at 750℃ and the material has a single perovskite-like structure at 900℃.

XRD测试图谱表明在La_4BaCu_5O_13＋δ B位掺杂Co和Ni的材料在750℃以下时材料中则仍会有部分杂相存在。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。

The cost of moving grain food products was unchanged from May, but year over year are up 8%.

粮食产品的运输费用与5月份相比没有变化，但却比去年同期高8％。
