May, upon request, to produce square, round, ring, tile-shaped, curved, Shenyang the first hole and wire-cutting and other special-shaped shape, could be the appearance of plating white zinc, color zinc, blue zinc, nickel, nickel, copper and nickel, gold, etc..

可根据要求生产出方形、圆形、环形、瓦形、弧形、沈头孔及线切割异形等形状，并可将外表电镀成白锌、彩锌、蓝白锌、镍、镍铜镍、金色等。

Thus the chemical composition of intermediate A is that of nickel nitrate tetrahydrate, that of intermediate B is of nickel nitrate dihydrate, that of intermediate C is of the monohydrate whilst that of D is anhydrous nickel nitrate.

因此，中间产物A的化学成分是四水硝酸镍，中间产物B的化学成分是二水硝酸镍，中间产物C的化学成分是一水化物，而中间产物D的化学成分是无水硝酸镍。

In order to achieve the low temperature process, we used metal-induced lateral crystallization to fabricate it . Ni can lower the temperature of process and annealing time because the reaction between Ni and Si of forming Nickel Disilicide(NiSi2) which lowers the annealing time in further process.

在低温制程上采用的是金属侧向诱发结晶(Metal-induced Lateral Crystallization)方式，此方式是使用镍降低制程的温度以及生长时间，原理主要是藉由镍与矽之间的反应产生二矽化镍(NiSi2)，进行退火后可产生金属诱发结晶与金属侧向诱发结晶两种结构，再进行其微结构观察。

With the increasing of oxygen content in flu ratio during sputtering, the electrocatalytic activities of the film increase.

与镍相比，氧化铁镍是更理想的催化阳极材料，当电流密度为50 mA/cm2时，其氧的过电势比镍的下降了500mV。

Two skeleton nickel catalysts A and B were prepared at 50 ℃ and 90 ℃ respectively and hydrogenation of furfuryl alcohol to tetrahydrofurfuryl alcohol was studied with the catalysts under different reaction conditions.

研究了以骨架镍为加氢催化剂，以糠醇为原料制备四氢糠醇。在中温和高温下制备了两种骨架镍催化剂A和B，研究了不同的反应条件对两种骨架镍催化剂的影响，确定了最佳反应条件。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
