张力的

Three types of interfacial tension curves were observed. The first curve comprised two curves that were located on either side of 1:1 molar ratio, and the interfacial tension decreased with the increase of excessed surfactant component. The second one was a saddle-shaped curve that strode over the 1:1 molar ratio. The third type was a saddle-shaped curve that was located beside the 1:1 molar ratio.

观察到三种界面张力曲线类型，第一类为摩尔比1：1的两边的两条曲线，界面张力随过剩表面活性剂组分的比例增加而降低；第二类为一条跨过摩尔比1：1的马鞍型曲线；第三类为位于摩尔比1：1的一边的一条马鞍型曲线。

The results of magnesium and calcium ions tolerance test indicated that the modified SPS, synthesized from the above two methods,has good chelation with magnesium and calcium ions for the crablike carboxyl and ester group and increase the reaction weight with magnesium and calcium ions for addition of hydrophilic group.Both of the two modified petroleum sulfonates could produce ultra-low interfacial tension at calcium and magnesium ions concentration lower than 600 mg/L,whereas the general petroleum sulfonates could only produce ultra-low value below 300 mg/L.

耐钙镁离子能力测试结果，以大庆炼化公司两种渣油为原料，采用上述两种合成方法制备的改性石油磺酸钠，由于产物中引入蟹爪状羧酯基，对钙镁离子有较强的螯合作用，同时增加了亲水基，增大了表面活性剂分子与钙镁离子的反应量，因而在600mg/L的钙镁离子溶液中获得10-3级的超低界面张力；而普通石油磺酸钠仅能在300mg/L的钙镁离子溶液中获得超低界面张力。

The main work is as followings: First, we use KE SI DA microscope for observing the appearance and configuration of bicomponent fiber. It was found in the bicomponent fiber it is a bilateral array for the PET and PTT. The cross section is anisomerous with PTT and PET side by side. After heat treating the shape of single filament becomes three dimensional curly and the number of crimp is biggest in the condition of relaxation. In the range of some tention, the bulkiness and crimpness fall obviously after the bicomponent fiber is treated with heat.

首先利用科视达观察了PTT/PET双组分复合纤维的外观形态，发现PTT/PET双组分复合纤维中PTT、PET两种组分呈双边分布，横截面呈不对称的哑铃状，PTT和PET两组分分居在横截面两侧，单丝经热处理呈现出三维立体卷曲，在无张力条件下卷曲数最多，在一定的张力范围内，随着所加负荷的增加，PTT/PET双组分复合纤维热处理后的蓬松性及卷曲性均下降显著。

And have driven compared to shaftless tension control more flexible, but variable conditions also tension control more difficult, and that's asked us to practice in the trial and the law, achieve the best fit mode.

与有轴传动相比，无轴传动的张力控制更加灵活，但可变因素的增加也提高了张力控制的难度，这就要求我们在实践中不断摸索三者的规律，达到最佳的配合模式。

After feeding, the volume of material roll of a central location that is, the business card printing and membership card making location, because this machine is affixed with a deviation, version, and so on are in sub-subparagraph to the central axis as the base, the material should be in strict accordance with our equipment for each feed routes through the guide roller is, put to paper machine for printing paper smooth and adjust the tension and cause to be printed materials subject to certain harmoning tension control in order to ensure the rectification of overprinter precision, adjustment, so that the material in the press and printing center position, to ensure that the rectification action ofsmell is correct.

上料卷之后，料卷的中心位置也就是制卡和会员卡制作位置，因为贴版纠偏、模切、分节等都是以中心轴为基准的，被印材料应严格按照本台设备的送纸路线穿过各个导纸辊、穿纸后可开动机器让被印材料送纸平稳，调节张力，使被印材料受到一定的平稳张力控制，才能保证套印精度、调整纠偏，使材料在印机及印版中间位置，以确保纠偏动作的灵敏无误。

Resolve the polychromatic business card printing and membership card making misregister, first of all, each color section of roll a pressure slightly larger, so that we can make all of the colors that exerted by equivalent; and second, note that the adjustment of each business card printing and membership card-making machine for the front and back are feed roller and traction roll of clearance and location, and in particular reducing the size of the Board-width.

处置多色制卡和会员卡制作套印禁绝的题目，首先，每种颜色的版辊部答比后一个不张力稍不小一些，这样才能使所有颜色上承受的不张力不等；其次，夺目调动每部制卡和会员卡制作机的后部和后部均有进纸辊和牵引辊的间隙和场所，出格是在纸板宽度功窄时。
