Further, the prior coating methods for shielding electromagnetic wave of electronic equipments include three kinds of methods including 1 a vacuum metalizing wherein the metal is vaporized and deposited on the material surface under vacuum; 2 a conductive paint spray wherein the solution containing

此外，先前的对电子设备进行电磁波屏蔽的涂层方法有三种方法，包括1）真空金属镀层，这里，金属在真空下被蒸发并沉积在材料表面；2）导电涂料喷溅，这里，含金属粉末的溶液被喷雾到材料表面；3）化学镀，这里，待涂覆的

Besides, the cuticles that resist external invasions can be ridded of with fruit acids so that DNA vaccine wrapped with liposome can pass the skin.

而肤表面的角质层，会将很多外来的东西阻挡在外，因此只要先透过果酸把角质层去除，被微脂体包覆的DNA疫苗就可经皮传输进入体内。

The invention provides a method for preparing a tube-shaped cathode of a direct methanol fuel cell, belonging to the fuel cell field and comprising the steps of: dispensing a single solution for gel injection molding at first, then adding a mesophase bituminous coal micro ball into the single solution and stirring evenly to obtain stable slurry, then casting the slurry into a die, preserving heat until the single solution reacts with a cross-linker completely to obtain a carbon-biscuit, after drying and sintering the biscuit in vacuum, preparing a diffusion layer and a catalyst layer on the surface by dipping process, and then coating polyester electrolyte membrane with a burette, rolling the carbon on a warm table to solidify the electrolyte membrane.

一种制备直接醇燃料电池管状阴极的方法，属于燃料电池领域。本发明首先配制凝胶注模用单体溶液，之后将中间相沥青炭微球加入到单体溶液中，搅拌均匀得到稳定的浆料，然后将浆料浇注到模具中，保温至单体与交联剂完全反应，得到炭管素坯，将素坯烘干、真空烧结后，在其表面采用浸渍工艺制备扩散层、催化剂层，然后采用滴管涂覆聚合物电解质膜，在加热台上对炭管进行滚压，使电解质膜固化。

Spreading cover on a stone material surface, not only is to cover the stone material hair side, hollow, crack and scratch, enhances the stone material glossiness, but also to protect the stone material from the water or other bad factors, like SO2 and so on noxious gas has corrosive nature to the stone material, thus to avoids or postpone stone material surface oxidation, so to have the protection function.

在石材表面涂覆一层遮盖品，不单纯是为了掩盖石材毛面，凹陷、裂纹和划痕，提高石材的光泽度，还可保护石材免受水或其他不良因素，如SO2等有害气体对石材的侵蚀作用，避免或延缓石材表面氧化作用的发生和发展，从而起到保护的作用。
