The solubility limit of element Ta in binary compound NiZr2 wasdetermined as 13.5 at% at the present experimental temperature.3 The investigation of the phase equilibrium relation arid the thermodynamic extrapolation of Ni-Cr-Zr ternary system at 1173 KThe isothermal section of Ni-Cr-Zr ternary system at 1173 K was determined and the phase equilibrium relation and their stability were analyzed and discussed.

同时，利用文献所报道的有关该体系的相关二元子系统的热力学信息成功地外推和预测了该三元系的热力学性质。

The wall of the burning chamber was pitted at the beginning then gradually burnt through.By means of the Bunsen burner,tubular furnace and XRD,SEM,EDS,this special type of high-temperabure destruction was studied.It was found that the phenomenon is resulted from the combined action of CO and lower hydrocarbon on Ni-Cr alloy.Firstly,Ni-Cr alloy is carbonized and selectively oxidized by CO to produce Cr2C,Cr3C2 and Ni-Cr2O3,while the capillary cracks in the surface layer are formed simultaneously.

作者利用几种现代手段和试验方法，对这一燃烧破坏现象进行了系统地模拟研究，发现这是CO和低分子烃在高温下对合金共同作用的结果：第一步CO作用使合金表层发生氧化和碳化，造成裂隙；第二步低分子烃扩散进裂隙并在Ni-Cr2O3微粒的催化下，裂解生在石墨炭并包复在Ni-Cr2O3微粒周围，体积增大。

In the charge-discharge tests, for the electrode irradiated by light and charged with current simultaneously, the discharge time is about 11.4 h, much longer than that (about 8.7 h) charged only with current, indicating obvious photo-assisted chargeability of the electrode. The additional discharge capacity is contributed to the photocharge of photogenerated electrons and holes.

HSA／Cr-BIO电极在200μA电流与光照同时充电时比仅200μA电流充电后放电时间长(11.4小时vs8.7小时)，所增加的放电容量来自光生电子与空穴对储氢合金电极的充电，表明该HSA／Cr-BIO电极具有明显的光辅助充电性能。

Common Reflection Surface stack is a brand-new and special ZO imaging method, the theory of CRS stack stems from paraxial ray theory, the biggest difference between CRS stack and conventional ZO imaging method is that it consider a reflector R as a circular reflector segment Cr placed in the vinicity of reflector R, Cr can be seen as the second order approximation of the reflector. The CRS traveltime surface is the multi-coverage reflection response of the reflector mirror assigned to R.

共反射面元（CommonReflection Surface=CRS）叠加技术是一种全新的、特殊的零偏移距剖面成像方法，CRS迭加理论源于傍轴射线理论，它与普通的零偏移距剖面成像方法的最大区别是它认为地下反射层是由许多个小反射弧段互相叠合组成的，认为来自某反射点附近的一个邻域内的反射信息都可以对该反射点的成像作出贡献，因此对该反射点进行零偏移距成像时就应该聚焦更多的能量参与迭加。

Experimental results show that the algorithm can segmentalize ROI effectively, CR is higher than 30, PSNR of the whole image is higher than 42 dB, and the object keeps original fidelity. Inter-frame CR is about 7, background has cumulative error and PSNR is higher than 40 dB.

实验结果表明，该算法在帧内能有效地划分感兴趣区域，压缩率在30以上，峰值信噪比在42dB以上，目标无失真；帧间压缩的压缩率在7左右，背景区域有误差累积，但整体图像的峰值信噪比都在40dB以上，目标无失真。

we use magnetron sputtering to deposit Al-AlN particle film as SED's electron-emitter. The Cr-Cu-Cr electrode was prepared by electron beam vaporize deposition. The voltage used to electroform the cracks are periodic trigonal wave and the breadth of the voltage are increasing gradually.

文章中采用铝-氮化铝薄膜材料作为SED器件的电子发射层，采用磁控溅射的方法镀电子发射层，采用电子束蒸发的方法镀铬-铜-铬材料作为电极；电形成过程中采用电压幅值恒定、周期性重复的脉冲和电压幅值渐增的电压脉冲作为电极电压。
