Influences of basic component (fiber, redispersable emulsoid powder, water-retentive admixture, expansive admixture, mixture and cement-to-sand ratio )of Dry-mixed Mortar on essential performance of mortar have firstly been summarized. The results show that :(1) After fiber is mixed into Dry-mixed Mortar , toughness ,crack resistance and unpermeability of mortar will be improved; Influence of different length mixed fiber on toughness of mortar precedes single-length fiber, but influence on crack resistance of mortar is the same.

该文首先研究了干拌砂浆的基本组分：纤维、可再分散乳胶粉、保水剂、膨胀剂、掺合料以及灰砂比对砂浆的基本性能的影响，结果表明：(1)在干拌砂浆中加入短切纤维，可以使砂浆的韧性得到改善，提高砂浆的抗裂性、抗渗性；不同长度的纤维进行混杂后对砂浆韧性的提高比单一长度纤维具有更好的效果，但对砂浆抗渗性的改善效果与单一长度纤维差别不大。

The sludge in SBMBR1 presented granular characteristics and settled very well. The sludge in SBMBR1was brown and the sludge flocs was smashed by the shear force due to high intensity of aeration. The sludge size decreased and the sludge flocs blended with water forming ropy solutions, and there was no distinguish interface between water and sludge. Low sludge age and high loading operation enabled the sludge in SBMBR1 keeping higher sludge activity and the MLVSS/MLSS ratio and SOUR values of SBMBR1 were higher than SBMBR2. Both in SBMBR1 and SBMBR2, there were large amount of zoogloea, bacillus, coryneform of bacteria, and pediococcus. However, in SBMBR1 there were also a lot of Protozoa like epistylis and etc. A certain amount of filamentous bacteria can also be found in SBMBR1. The biological species in SBMBR1 were much more abundant than that in SBMBR2.3. Membrane fouling on flat-sheets membrane was observed and analyzed with AFM, SEM and TEM. After the measurement of membrane surface EPS and membrane surface ETX analysis, the pollutants composition on the surface of flat-sheets membrane was calculated.

从外观观察SBMBR1反应器中的活性污泥呈浅黄色，随着运行时间的增加，污泥粒径逐步增加，SV、SVI值逐步下降，呈现出较强的颗粒特征，沉降性能良好；SBMBR2污泥呈土黄色，污泥絮体被高强度的曝气所产生的切应力所打碎，污泥粒径迅速降低，絮体较为细碎，和水相混合成均一粘稠的溶液，看不到泥水分界面；低泥龄、高负荷运行，使得SBMBR1可以保持较高的微生物活性，MLVSS/MLSS值、SOUR值均高于SBMBR2；两级反应器活性污泥中均有大量的菌胶团，长杆菌、短杆菌和球菌是构成主体，但SBMBR1活性污泥中含有大量固着型原生动物如累枝虫等，还存在着一定数量的丝状菌，生物相要比SBMBR2丰富。3、借助原子力显微镜、扫描电镜、透射电镜等手段对平板膜污染现象进行观测和分析，并通过膜表面污染物EPS测定、污染膜表面能谱分析，得出平板膜表面污染物的组成。

In addition, ppg provides industrial coatings to various companies including haier, nokia, motorola, whirlpool and dell. ppg architectural coatings are widely used in many well-known structures including those in tian anmen square and the flag post, beijing oriental plaza, beijing international exhibition center, beijing international airport, the shanghai jinmao building, shanghai pudong international airport, shanghai oriental pearl tower, guangzhou baiyun international airport, tianjin jinhuang building and taida building.ppg's fiber glass business entered china's marketplace in the 1980s and established manufacturing sites in taiwan jiayi, jiangsu kunshan and shandong zibo. in march 2006, the world's largest fiber glass furnace, costing $120 million, was put to production in kunshan, boasting more than 70 thousands tons of output. in 2006, ppg invested jointly with sinoma in zibo to launch a fiber glass plant that will have more than 200,000 tons of annual output.

除涂料业务外， ppg的玻璃纤维也于80年代进入中国，并已先后在台湾嘉义、山东淄博和江苏昆山投资了生产基地；2006年3月，在昆山基地投资的1.2亿美元，年产7万吨的世界最大的玻纤丝窑正式投产；2006年与中材金晶合作在淄博投资建成了一个年产20万吨以上的玻纤生产基地；并计划在苏州与必成实业共同设立一个玻纤研发中心，以支持ppg在亚太区客户的应用问题。ppg玻纤在全球共拥有九座生产基地，并四座研发中心，以及遍布世界营销与技术服务网的全球玻纤领导者，制造连续拉丝玻璃纤维产品，包括短切纤维、直接纱、玻纤纱、无捻粗纱和玻纤卷物等。
