The spectacle fittings has novel style and complete breed whose main material are brass, cupronickel, phosphor copper, nickel, mangansese alloy, aluminium magnesium alloy, stainless steel, memory metal and other kind of hardware goods fitt

配件部：眼镜配件款式新颖品种齐全，主要材质有：黄铜、白铜、磷铜、镍、锰合金、铝镁合金、不锈钢、记忆金属及其它各类五金制品配件等。

The result shows that modification can make the β-Si phase thin when the joining amount is 0.3wt%, making the best modification result. Alloying elements Mn and Ni are always used to neutralize iron"s harm in aluminum alloys. They can form many kinds of complicated metallically compounds with Fe and Al, and eliminate needle-like iron-rich phases to reduce iron"s harm in Al-Fe alloy. Copper makes the alloy microstructure thick and electromagnetic stirring obviously makes the alloy microstructure thin, round the second phase, when the stirring voltage is 200V, making the best result; Reheat makes liquid phases emerge in the alloy, when the warming temperature is 650?

研究结果表明：红磷可以明显细化合金中的初晶硅，当加入量为0.3wt%时，取得最佳变质效果；锰、镍合金中加入后，通过形成多种复杂金属间化合物，细化针片状富铁相，减小铁对铝硅合金性能的危害；铜使合金微观组织发生粗化；电磁搅拌明显细化合金组织，使第二相圆整化，搅拌电压为200V时，取得最佳细化效果；二次加热使合金组织中产生部分液相，在650？

Of the surface treatment and coating and electrophoresis (add color, drop, sand blasting, Lassa, Flower paper packets) has extensive experience in product quality has passed through the Far East and 12,870 standard test with the ISO9001: 2000 international quality standard management system demonstration.

本厂是专业眼镜电镀厂，成立于1999年，全厂现有人员300多人，厂房占地面积12000余平方米，拥有完善的环保设施经市区、街道办环保部门批准），对各种眼镜及精密五金金属（白铜、锰合金、铁、铍铜、不锈钢、无镍、铜、钛、B钛等）的表面处理和喷涂及电泳（加色、滴油、喷砂、拉沙、包花纸等）有丰富经验，产品质量已通过远东和12870标准测试与ISO9001：2000国际质量标准管理体系论证。

Low ohmic Manganin resistors for battery and energy management in cars and trucks.

低阻值锰镍铜合金电阻主要用于轿车和卡车的电池及电源管理。

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。
