And then the effects of compositions on the mechanical performance, characteristic temperatures, thermal expansion and chemical stability of the glass were discussed. Researches on lead borate sealing glasses show that PbO/B2O3 ratio exerts the most important effect on glass network. ZnO is beneficial to stabilize the glass against devitrification . Bi2O3 has little effects on the sealing temperature, while it helps to adjust the thermal expansion coefficient of lead borate glasses in a definitive range. When 0.5～4 mol% GeO2 is introduced, the glass possesses the highest stability and lowest sealing temperature (400 ?C), which is desirable for low-temperature sealing.

通过对含铅的硼酸盐封接玻璃研究得出，PbO/B2O3比是影响玻璃网络最主要的因素；添加ZnO有助于增强玻璃的稳定性，抑制析晶；Bi2O3对高铅系列配方玻璃的封接温度影响不大，但可使铅硼系列玻璃体系的热膨胀系数在一定范围内可调；在高铅系列配方中，引入0.5～4mol%的GeO2可有效地抑制玻璃析晶，降低封接温度；最终获得了两种性能较好的低熔点铅硼酸盐封接玻璃配方，G3封接温度低达400℃，其PbO含量为54mol%左右，BL10玻璃的封接温度为440℃，但其铅含量大大降低，仅为36mol%。

It is the exterior link problem of a website again, generally speaking, exterior link is more, the quality of the website of the link is higher, better to the rank of your website, but this is not to say to if,jump over good; more more absolutely outside group of hair machine are sent suddenly, connect, the will be GOOGLE penalty that awaits then is the problem of retrorse link next, namely if your website is done perfectly if, other website can add your website link on his page, of course this also can pass commutative catenary fetch to come true.

再次是一个网站的外部链接问题，一般来说，外部链接越多，链接的网站的质量越高，对你的网站的排名越好，但这绝不是说越多越好；如果把有群发机猛发外连，那等待的将是GOOGLE的惩罚然后是反向链接的问题，即你的网站如果做的相当不错的话，别的网站会在自己的页面上加上你的网站链接，当然这个也可以通过交换链接来实现。

The effects of different factors on the laser-induced graft polymerization on the PET surface were analyzed, and the mechanisms were discussed. The factors were: 1 Monomers with smaller molecules resulted in better modification than polymeric monomers. Acrylamide monomer was chosen as hydrophilic modifier finally; 2 Higher concentration of the monomer solution favored the graft reaction; 3 With the increasing laser fluence, the surface hydrophilicity of PET films increased at first, then decreased. More laser pulses led to a more hydrophilic surface; 4 Benzophenone as a photosensitizer hindered the graft polymerization; 5 The homopolymer retardant of ammonium iron sulfate hexahydrate in a proper concentration retarded the formation of homopolymers and promotes the graft copolymerization; 6 The solvent of monomer solution also affected the graft reaction. Different solvents functioned in different ways. Ethanol can promote the graft reaction because of the activity of hydrogen in its structure; 7 pH value of the monomer solution affects the polymerization rate, and a lower pH value was favorable to the graft reaction.

这些影响因素的作用分别为：1小分子单体的表面改性效果好，确定以丙烯酰胺为亲水性改性单体；2较高的单体溶液浓度有利于接枝反应；3激光能量密度增大，薄膜表面亲水性先显著增强，后又减弱；激光脉冲次数越多，改性后表面亲水性越强；4光敏剂BP对PET表面接枝聚合反应有阻碍作用；5适当浓度的均聚物抑制剂六水合硫酸铁铵能减少单体均聚物的生成，促进接枝聚合；6单体溶液的溶剂也影响接枝聚合的反应进程，不同溶剂的影响作用原理不同，含较活泼氢的乙醇能促进接枝反应；7溶液pH值影响单体聚合速率，pH值较低有利于接枝反应。
