According to the feature that deformation resulted from water absorption and mildew appear mainly on the rabbet surface of ccf , this paper adopts rsst to spray a special waterproof sealant on rabbet surface of ccf , so that the sealant can get into fiberboard to certain extent by means of capillarity and penetration , blockage the holes between fibers and capillary , cut up passage of water and change the properties of soakage and sorption to water in capillarity and fiber . at the same time , solidified sealant can form a compact waterproof pellicle on rabbet surface so as to prevent water and humidity from fiber ' s expansion and mildewing

针对吸水变形、霉变主要发生在地板企口表面的特征，采用企口表面全封闭法，在复合强化地板企口表面喷涂特殊的防水封闭剂，使其依靠毛细管作用及渗透作用进入板内一定深度，堵塞木纤维之间的空隙及毛细孔通道，截断水分传递的渠道，并改变毛细孔壁及纤维的表面性质以不利于水的浸润与吸附，同时其固化后能在企口表面形成一层致密的憎水薄膜，防止水分、湿气从企口侵入板内引起木纤维膨胀变形、发霉等现象。

Polymethyl methacrylate is the most used filling materials at present; There is not significant difference between unipedicular and bipedicular vertebroplasty; Using vertebral body venography and appropriate dense bone cement can reduce leakage of bone cement; Bolster for self-replacement can rebound vertebral body height, and balloon kyphoplasty and sky bone expander kyphoplasty can be avoided; In order to reduce refracture of vertebral body, anti-osteoporosis drugs should be used in the treatment of percutaneous vertebroplasty.

聚甲基丙烯酸甲酯是目前最常用的填充物；单侧注射和双侧注射疗效没有明显差别；应用对比剂及掌握合适的骨水泥黏稠度可以减少骨水泥的渗漏率；成形前腰部垫枕自身复位可以恢复椎体的高度，避免采用操作复杂及价格昂贵的球囊后凸成形及骨膨胀椎体后凸成形；进行经皮椎体成形时应该配合应用抗骨质疏松药物，以减少椎体再骨折的发生。

How to improve the performance of this kind flame retardant material is still a key problem for its application.

结果表明：膨胀床器外预硫化工艺，优于CS2器内硫化工艺，对裂解汽油二段加氢精制催化剂、石蜡加氢再生剂、加氢裂化预精制剂和柴油加氢精制剂均具有较好的硫化效果。

Coal and montmorillonite and intumescent flame retardant have good synergist flame retardant effects.

煤、蒙脱土及膨胀型阻燃剂之间存在良好的协同阻燃效应，可使聚乙烯的极限氧指数得到一定的提高。

The results showed that the rhizosphere medicine could increase survival rate, height, DBH, relative turgidity of bark and tree capacitance and decrease morbidity and contagious index dramatically. Two kinds of application methods were adopted: one was called the soil-mixed method and another called the root-dipping method.

结果表明，根际微生态保健剂对造林成活率、树皮相对膨胀度、树体电容、树木的高生长和胸径生长具有明显的促进作用，对林木的发病率和感病指数有明显的降低作用。

The influence of rhizosphere medicine in different components and application methods on the survival rate, height, DBH, relative turgidity of bark, morbidity, contagious index and tree capacitance of Populus hopeiensis were studied.

The conclusion was the growth of bubble core with the increase of the adhesive when the bond lost definite water, while the key essential of making nicer performance cushion was to control the time and temperature of vesicant decomposed as well as adhesive of the mixture.

实验结果表明，膨胀珍珠岩缓冲衬垫的气泡核长大是在黏合剂失去一定的水分，其黏度逐渐增加的条件下才得以实现。控制好发泡剂分解时刻，分解速度与料浆的黏度相匹配，是制备优良性能衬垫的关键。

The above-mentioned T8 glass-ceramic showed only 25 % decrease in IR transmittance, 17 % increase in hardness, 61 increase in dilatometric softening point, and 19 % increase in Young s modulus.

上述试片之IR穿透率与T8起始玻璃比较，仅下降了25 %，但硬度上升了17%；与未添加成核剂的玻璃比较，膨胀仪软化点上升约61℃，杨氏系数上升约19 %。

The results showed that when 0.3 g of divinyl benzene was used as crosslinking agent, the crosslinking degree increased significantly from 28.26% to 90.95% with the increase of MAA amount from 4.0 mol% to 10.0 mol%, and this increase became slowly as MAA amount was more than 10.0 mol%; the particle volume expansion was increased gradually as MAA amount increased, and reached a maximum of 42.1% when 12.0 mol% of MAA was used, and perfect porous morphology inside particles was observed even when the crosslinking degree reached 95.4% at 14.0 mol% of MAA.

结果表明：在交联剂二乙烯基苯用量一定(0.3 g)的条件下，随着MAA用量从4.0 mol%增加到 10.0 mol%，聚合物交联程度从28.26%迅速增大至90.95%，当其用量超过10.0 mol%后 P x增大趋势变缓；随着MAA用量的增加，处理后胶粒体积膨胀百分率逐渐增大，在MAA用量为12.0 mol%时Δ V 达到42.1%的最大值，当MAA用量增大到14.0 mol%时，尽管 P x高达95.44%，胶粒仍具有完好的孔状结构。

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。
