Our result has shown that within several seconds of 600 W, Ar, O2 or N2 plasma pretreatment, PP fabric and PE film are activated at surface, so as surface tension of film and capillary attraction of fabric are both augmented.

实验结果显示：对於 PP 不织布与 PE 膜，以600 W 激发 Ar 、 O2、 N2三种气体电浆处理，皆可於极短时间约数秒至数十秒，即可使基材表面活化，形成亲水性或增进表面的毛细作用。

In addition, we have also measured the contact angle that stilled water contact with powder-graphite with the capillary rise method based on Washburn's equation.

石墨粉末表面色散自由能为21.8mJ.m-2，极性自由能为1.8mJ.m-2，总的表面自由能约为23.6mJ.m-2，以色散自由能为主。这是去离子水能够湿润石墨粉末，但湿润性相对较差的一个原因。

The result indicates that the high pH concrete pore solution can reduce corrosion of Cl~ on the carbonize steel.

结果表明，高pH值的混凝土孔隙液能减缓氯离子对碳钢的腐蚀；当pH≥13.6时，在NaC l浓度小于3%的混凝土孔隙液中，碳钢表面因生成钝化膜而不被腐蚀；当pH≤9时，混凝土孔隙液中无论是否存在C l-，碳钢均会被腐蚀；当pH=12.5时，混凝土孔隙液中NaC l浓度小于0.05%，碳钢则不被腐蚀；当混凝土孔隙液中的C l-浓度达到临界氯离子浓度时，碳钢表面的钝化膜开始损坏而被腐蚀，碳钢的腐蚀速度随着C l-浓度的增加而增大。

Medium does not scale, congeal, sinter or carbonize on the surface, and so is ideal heating element for viscous, and heat sensitive liquid medium.

加热器管表面功率负荷低，介质不会在表面结垢、粘结、烧焦、碳化等，是粘性、热敏性液体介质加热的理想元件。

Sees only the twinkling of an eye time, suffers the corrosion to change the yellow left hand outer space glove, the sudden color changes gradually black, the surface starts the crack to carbonize, this time Huang Qu senior official yellow Jinlong already obviously felt, the left hand points to the end to start to give off heat; This kind of corrosive steam has finally revealed the ominous ruthless unusual truth about the matter, this sudden gradation lets the human be virtually impossible to guard against, is following the strong corrosion permeability, before long on perish entire outer space glove outer layer and fast thorough in, Huang Qu senior official yellow Jinlong had a premonition the situation is not wonderful, wants to return to the planetoid control center immediately, in order to takes off the outer space glove under the artificial environment which this only bad luck passes goes against, because in on this high speed movement planetoid, the surface temperature may melt the steel and iron, once casts off the outer space glove, the flesh and blood constitution manpower can instantaneous burn, and can threaten human's entire life immediately!

只见一眨眼功夫，遭受腐蚀变黄的左手太空手套，突然颜色逐渐变黑，表面开始裂纹炭化，此时黄区长官黄金龙已经明显地感觉到，左手指端开始发热；这种腐蚀性蒸汽终于露出了凶狠异常的庐山真面目，这突然的渐变让人防不胜防，伴随着强劲的腐蚀渗透性，不一会儿就腐蚀掉了整个太空手套的外层并快速深入内部，黄区长官黄金龙预感到情况不妙，想立即返回小行星指挥中心，以便在人工环境下脱下这只倒霉透顶的太空手套，因为在这颗高速运行的小行星上，表面温度可以熔化钢铁，一旦摘掉太空手套，血肉之躯构成的人手就会瞬间被烤焦，并会迅即威胁到人的整个生命！

Carborundum, emery abrasive carborundum powder is applied to two kinds of dry and wet production process of the most affordable of the abrasive, especially for the more rough treatment of the workpiece surface, while the treated surface, also requested a more elaborate occasions.

金刚砂，金刚砂磨料，金刚砂微粉是一种适用于干式和湿式两种生产工艺的最经济实惠的磨料，尤其适用于对较粗糙的工件表面进行处理，而处理后表面又要求较精细的场合。

In this paper, we synthesized two kinds of new carboxylate Gemini surfactants and one of new bis-quaternary ammonium salt.

本论文共合成了两种新型羧酸盐Gemini 表面活性剂和一种新型季铵盐Gemini 表面活性剂。

Different types of surfactant have different adsorption on oil sand, and carboxylate surfactant has the least adsorption.

不同类型表面活性剂在天然油砂上的吸附量存在差异，羧酸盐类表面活性剂在天然油砂上的吸附量最低。

Synthesis and application of fatty alcohol ether carboxylate .
