Magnetic permeability: The ratio of the magnetic induction B to the inducing field strength H; denoted by the symbol :=|B|/0|H| 0 is the permeability of free space = 4π 10-7 weber/ampere meter (or henries/meter) in the SI system and 1 gauss/oersted in the cgs system, so that the permeability is dimensionless.

磁导率 磁导率：磁感应强度 B 与源场强度 H 之比，用符号表示：=|B|/0|H|自由空间磁导系数 0 在国际单位制中为 4π 10-7 韦伯/安培米，在厘米-克-秒单位制中为 1 高斯/奥斯特。因此磁导率是无量纲的。

Peripherin-kizami effect of holography: adoption of the photoetching machine computer programming walk-by-bit imaging technology and identifies the surface brightness, along with the change of the perspective that identifies the patterns occur within the rules of a beautiful animation, plus a hierarchical pattern can be a strong level of icing on the cake and more graphics and text content, the user thereby to protect their products from others phishing as well as the purpose of improving the products concerned and show their uniqueness and uniqueness, thus increasing the added value of coplasticizer products and enhancing brand image.

动感光刻成果激光全息：堵住光刻机电脑编程行位办理技艺成像，标志暗地亮度极佳，随着视角的保持，标志边的图案会呈不隐法规而标致的不静态成果，加上图案的不合层办理，更可获得很不弱的条理立体感和较众的图文边容，用户由此到达爱护自己的产物免遭他人仿冒的纲的，既能提矮产物档次，又表不隐其单共性和惟一性，从而补充日化产物的附加值和晋升品牌不隐象。
