耐磨性

The bamboo is exempted from pesticide contamination because it can produce negative ion itself and has the insect-preventive and anti-microbial functions, which can protect it from diseases and insect damage. Moreover, the bamboo fiber is produced by high technology without the addition of chemical additive, and it is characterized by various properties such as natural antibiosis, bacteriostasis, anti acarid, deodorization, anti-ultraviolet, and excellent ventilation, instant water absorptivity, strong wearing resistance, outstanding dyeing property and beautiful appearance, etc.

因为竹子自身能产生负离-和防虫抗菌作用，生长过程中因无病-虫害而免除了农药的污染；并且竹纤-在制造全过程中采用高科技手段，不-任何化学添加剂，并具有天然抗菌、-抑菌、防螨、防臭和抗紫外线作用，-有良好的透气性、瞬间吸水性、较强-耐磨性、良好的染色性、美观性等优-良的特性。

In addition, when the modified PVA resins fulfilled requirements in the following: 1 the acetalization degree varied from 60 mol% to 80 mol%, 2 the esterification degree varied from 10 mol% to 20 mol%, 3 the amount of hydroxyl group was 5-25 mol%, 4 the range of value of B/P(the mass ratio of the binder to diazo resin) was from 4 to 4.5,5 the range of its molecular weight was from 4×10^5 to 8×10^5, the negative PS plate obtained had excellent sensitivity, hydrophobic property, good developability, good ink receptivity and good scratch resistance.

因此其分子量、酯化度和缩醛度的确定，必须综合考虑各项性能之间的平衡。缩醛度为60-80 mol%，酯化度10-15mol%，羟基5-25 mol%，分子量约为4-8万，B/P为4-4.5时，制得的阴图PS版的感度、显影性、着墨性和耐磨性都较好。

Their weakness is resistance, heat resistance, the hygroscopicity and permeability is poorer, heat, easy to produce static deformation.

它们的缺点则是耐磨性、耐热性、吸湿性、透气性较差，遇热容易变形，容易产生静电。

Some moisture content can improve the penetrability of the compound impregnant in heartwood of Chinese fir.

在较低蒙脱土质量分数下，杉木/蒙脱土纳米插层复合材的吸湿性、吸水性、尺寸稳定性、抗水流失性、顺纹抗压强度、耐磨性、氧指数等性能均较酚醛树脂浸渍木有一定提高。

It is a kind of nontoxic, inodorous, transparent, low_cost, easy-made water glazing oil, and without VOC emitting. It is useful in packaging printing in food, medicine and tobacco fields etc.

由于水性上光油具有无毒，无味，透明感强，无有机挥发物的排放，成本低，原材料来源广等特点，在使用中能赋于印刷良好的光泽性，耐折性，耐磨性和化学品性，尤其是它所具有的环保性能特别适合食品，药品和烟草等行业包装印刷材料的加工。

The effects of reaction time,reaction temperature,content of hydroxyl propyl acrylateand n-propanol on the hydrophilicity of the films were discussed respectively.

这类材料一般兼有有机和无机材料的优点，如在保持有机高分子成膜性、透明性的基础上，又具有耐磨性、耐溶剂性、高硬度等优点[1]。

To ensure that the pipeline valve sealing performance to seal a vice excellent corrosion resistance, abrasion resistance, flexibility and self-enrichment.

为了保证管线阀门的密封性能，要求密封副具有优良的耐蚀性、耐磨性、自润性及弹性。

In addition, nanoscale clays can be added to the PUs to improve the stainproof, wearproof, hardness, stiffness and flame retard properties of the coatings.

此外，水性PU涂料添加奈米黏土可提高防污性，耐磨性，硬度，难燃性，强韧性等，提升了传统涂料产业之附加价值。

But the disadvatages are not good to wearing resistance,heat resistance,moisture pickup,and breathy, and easy to out of shape, to having statis, is could make any kind of cloth, but level is not going to become higher so that could go up better place..

它们的缺点则是耐磨性、耐热性、吸湿性、透气性较差，遇热容易变形，容易产生静电。它虽可用以制作各类服装，但总体档次不高，难登大雅之堂。

Sliding bearing not only pass working force,but also sustain high surface velocity,which require the material to have soft parts,in order to obtain fine working behavior and difficulty to damnify by extra impurity,and have hard parts to acquire fine wearability and fatigue strength.

由于滑动轴承既要传递作用力又要承受很高的表面速度，这就要求轴承材料既要具有软组分，以获得良好的运行性能，如磨合性、顺应性以及尽可能小的咬和倾向，且不宜被外来杂质所损伤；又要具有硬组分，以获得良好的耐磨性和抗疲劳强度。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.

气候直方图是将所收集的降水量测定值，分为几个相等的区间作为横轴，并将各区间内所测定值依所出现的次数累积而成的面积，用柱子排起来的图形，也叫做柱状图。
