The microstructures in the late stage of the creep have been observed by means of SEM and TEM. The results show that the microstructure corresponding to the macro-slip in the third stage of the creep is that a large number of dislocations shear into the rafted γ' phases,decreasing creep resistance of superalloy.

测定了[001]取向单晶镍基合金的蠕变曲线，并利用SEM和TEM对蠕变后期的微观组织结构进行了观察结果表明：蠕变第三阶段结构特征是大量位错切入筏状γ'相。

The curved line, linking the coordinates of point C, likes a "V" toward the outer of the primary curve. CONCLUSION: the straitening phenomenon was evident in preparation of S-shaped canals with hand-used Pro-Taper, and occurred mainly after instrumentation by F1 file.

手用ProTaper镍钛根管预备器械在预备重度弯曲细小的根管过程中有明显的根管拉直现象，且主要始于F1预备后。

TANG Zi-long SONG Shi-zhe (Department of Materials, Tianjin University, Tianjin 300072)GUO Ying-kai (Tianjin Professional College, Tianjin 300402)Abstract : The corrosion behavior of type 304 stainless steel and industrially pure iron, chromium, nickel in 1.0mol/L HC1 and their corrosion inhibition by piperidine were investigated by atomic absorption spectrometry, current vs time relation at constant potential and polarization curve measurements.

采用原子吸收光谱，恒电位下电流～时间关系和极化曲线测试等方法研究了304不锈钢、纯铁、铬和镍四种材料在0.1mol/L HCl中的腐蚀行为及哌啶的缓蚀作用。

Therefore, the content of an alkaline metal such as sodium and potassium that can be incorporated as an impurity into the metallic nickel powders can be significantly reduced.

因此，可以显著降低作为杂质引入金属镍粉中的碱金属如钠和钾的含量。

In this ***,nano-particles of NiCuZn ferrites powders were prepared with nickel nitrate,zinc sulfate,copper sulfate and ferrous sulfate as starting materials and ammonium oxalate as the precipitator by employing co-precipitation technique using oxalate precursors.Excellent composition uniformity NiCuZn ferrite powder can be obtained after drying and calcination.Toroidal samples were obtained after being formed and sintered.

本文以硫酸镍、硫酸铜、硫酸锌、硫酸亚铁和草酸铵为原料，应用化学共沉淀法制得分布均匀的先驱粉，经烘干、煅烧制成成分均匀性极佳的NiCuZn铁氧体粉末，再经成形和烧结等工艺，最后制得环形NiCuZn铁氧体材料。
