Among the various conductive fillers, carbon fibers have been proved to be a good candidate for EMI shielding. However, the electrical resistivity of a carbon fiber is much higher than the metal filler, so it must to use a greater number of carbon fibers in order to achieve the same shielding effect. In recent years, the Electroless plating is the new techniques of surface treatment of carbon fibers used to improve the electrical conductivity of carbon fiber. The copper-coated and nickel-coated carbon fibers have been proved to be a good candidate for EMI shielding.

导电高分子填充材料多使用碳纤维、碳黑及金属粉末，其中碳纤维具有高导电性、低密度及复合材料之补强特性，故本研究碳纤维作为填充材料，将碳纤维经过无电电镀处理，使其表面分别披覆金属镍及铜，增加碳纤维之导电度，混掺於聚丙烯高分子基材中，制成具有电磁波屏蔽功能之高分子复合材料，研究不同高分子成型方式与金属镀层对於碳纤维电学性质及复合材料电磁波屏蔽效益之影响。

According to the request of national regulation of verification of JJG259-1989 Standard Metal Tank and national technical specification of JJF1059-1999 Evaluation and Expression of Uncertainty in Measurement, the author adopted Type A and Type B uncertainty of evaluation methods. Standard uncertainty comes from various heft,liquid location difference in height of verified capacity measure,capacity of Gauge neck,difference in height of liquid location of gauge neck and standard capacity measurement.

根据JJG2591989《标准金属量器》国家检定规程和JJF1059-1999《测量不确定度评定与表示》国家技术规范的要求，通过采用不确定度A类和B类评定方法，具体分析包括被检量器的液位高度差，计量颈容量，计量颈液位高度差，标准金属量器等分量的产生及所引入的不确定度分量，从而获得标准金属量器测量结果的扩展不确定度。

The data of selected structure parameters of (C_5H_5)_3Ln· THF, such as the average distance between the penta carbon ring and the central metal, the distance between the penta carbon center or the coordinated THF and the central metal, showed that their values decreased with the increase of atomic number.

产物(C_5H_5)_3Ln·THF的特征结构参数，如五元碳环的碳原子与中心金属的平均距离，五元碳环质心与中心金属距离，配位的四氢呋喃氧原子与中心金属距离，由于&镧系收缩现象&，随着中心原子序数的增加而减小。

Imagine that you have a piece of wood and a number of metal pins comes out from it randomly,and you picked up an elastic rubber ban

想象一下，你有一块木头和金属针数出来从中随机，你买了一个弹性橡胶带和公开，用您的手广泛，包含所有的金属针，让它去你会发现，弹性橡胶带将萎缩，在金属引脚的松紧带外节单元，这些形式的凸包

In addition, cathodic protection can protect the metal electrode potential is more negative than the metal to protect the protected metal.

此外，阴极保护可用电极电位比被保护金属更负的金属来保护被保护金属。
