Entering the new century , the photoelectron industry gets the social extensive value , the information manifestation technique develop quickly , some business enterprises with real strengh and influence hold the led display screen industry as their main content in their stratagem of management and development , setting their feet in led display screen industry in succession 进入新世纪，光电子产业得到社会广泛的重视，信息显示技术发展迅速，一些具有实力和影响的企业把led显示屏产业作为经营发展战略的重要内容，纷纷涉足led显示屏产业。
The essay researched the compressive strength , bending strength , impact resistance and abrasion resistance of high strength polypropylene fibermesh concrete the mechanism of enhancing the properties of high strengh poloypropylence fibemesh road concrete composite was discussed and analyzed the regression on tensile strengh with portland cement mixed with fiber was derived using experiment the tensile strength of fiber soil stablization with porland cement was increased with dosage and length of fiber while the former was more effective than the latter test and analysis results indicate that polypropylene fiber can not only reinforce the strength of concrete , but also obviously promote the flexural fatigue life by the great stress the application of polypropylence fiber reinforced concrete in pavement construcion are also introduced 文章研究了不同掺量有机纤维混凝土的抗压、抗折强度、抗冲及性能、疲劳性能及耐磨性等各种路用性能，综合论述了有机纤维对水泥混凝土路用性能的影响。通过试验阐述了纤维水泥混凝土各种路用性能与纤维掺量、长度间的关系。分析表明纤维水泥混凝土随着纤维掺量和长度增加而增加，且纤维掺量对纤维混凝土抗拉强度的影响比纤维长度的影响更大。

The influence of different gypsum on strengh of portland - sulphoalminate composite cement system is complicated , related with aluminiferouse mineral in cement system and the so4 ( superscript 2 - ) concentration of its hydrated solution ; in distilled water and maximum lime wash , the dissolution rate of dihydrate gypsum is higher than that of anhydrite but the dissolubility is lower 石膏品种对硅酸盐硫铝酸盐复合体系水泥强度的影响较复杂，与水泥体系中含铝矿物及其水化溶液中so4 (上标2 - )离子浓度有关；在蒸馏水和饱和石灰水中，二水石膏的溶解速度比硬石膏快，溶解度比硬石膏低。
The experimental results are summarized as follows : the tensile strengh and bending strengh of steel fiber reinforced lightweight aggregate concrete can be improved significantly by the addition of steel fiber ; to some extent , the addition of steel fiber can also increase the compressive strength , although little , it radically improves the compressive toughness , and the steel fiber reinforced lightweight aggregate concrete will not fall apart with cracks ; with the increase of the volume fraction of steel fiber , the elastic modulus is also rising somewhat ; poisson ’ s ratio is influenced little with the addition of the steel fiber and the effect regularity displays unconspicuously 本文试验研究结果可归纳如下:钢纤维的加入能明显提高钢纤维轻骨料混凝土的抗拉强度和抗折强度;掺入钢纤维使钢纤维轻骨料混凝土的抗压强度有一定程度的提高,增长幅度不大,但抗压韧性却有很大改善,使钢纤维轻骨料混凝土裂而不散;钢纤维轻骨料混凝土的弹性模量随钢纤维体积率的增大有一定提高;泊松比受钢纤维的加入影响不大,规律性不明显。
The fracture strengh at room temperature of 95 . 2 % desity materials is lower than rbsc but higher than mosi2 ; the fracture toughness at room temperature is higher than mosi2 and reach the level of rbsc . when oxidated at 900 c , the evaporation of moo3 , co , co2 destroyed the oxidation film ( sio2 ) , the composite lost the weight because of the evaporation of moo3 . when oxidated at 1300 c , densitive oxidation film coverd the surface which composed by sio2 and mo5si3 在900氧化时，因为moo _ 3 、 co 、 co _ 2的挥发对氧化膜的破坏作用，无法在材料表面形成致密的sio _ 2氧化层，在该温度下复合材料表现为失重。在1300 ；氧化时，材料表面形成了致密的sio _ 2 、 mo _ 5si _ 3氧化层，复合材料先表现为失重，后表现为增重。
The analytic results of the effects on the micromorphological structure of the film by the electrochemical condition ' s showed that the carbon is apt to improve the boundary combination between the scfs and the surface of the cathode and the seperation of the films , and that the micromorphological structure of the mpgcfs is greatly affected by the dring and the power voltage , which remarkably affluence ion move in swelling cathode film , and that higher temperature and concentration of cu2 + in the medium solution are also advanagable to the deposition of cu in scfs . the plot of deformation behavior of mpgcfs showed that the maximum strench ratio decreases and the brittleness increases due to the existence of the metal phase , and that the strengh trend of the composite films is fistly up and down followed with the content of metal phase because of the change of the role of the metal phase from acting as the physical cross - linking to weakening the films due to destroying the whole structure of the polymer 另外它作为基体的另一个突出的优点是制备的溶胀复合膜( scf )中的溶剂与电解液中的溶剂相同都是水，克服了以前膜内外不同溶剂之间扩散的问题，结果使得电流最终趋于一种稳态，因此可以更好实现用电化学条件来控制mpgcf的形态结构；硬质石墨材料的多孔的结构和石墨本身的结构性能特点使得碳作为阴极材料时有利于溶涨复合膜( scf )与电极表面的结合以及膜的剥离，因此是作为阴极的理想材料；电化学条件中的干燥程度和电压能够明显的影响离子在膜内的迁移，从而对mpgcf的形态结构造成较大的影响；而提高反应温度和增大电解液中铜离子的浓度也有利于铜在膜中的沉积生长。
