To explore the hydration process of Portland cement-fly ash system, the reaction degree of fly ash and Portland cement,non-evaporable water content,amount of hydration products,porosity and compressive strength of pure cement pastes and cement-fly ash pastes were studied at various curing ages,water-to-binder ratio,and fly ash replacement percentages.

为考察粉煤灰对水泥水化进程的影响，系统研究了水泥粉煤灰浆体在不同养护龄期、水胶比、粉煤灰掺量下水泥和粉煤灰反应程度、非蒸发水数量、水化产物数量、孔结构和浆体力学性能。

Because there exist the problems of bad atomizing properties bad wearproof ability. Short working life and easy to be blocked in the CWS atomizers, the extending appications are greatly confined.

由于水煤浆喷嘴普遍存在着雾化粒度粗、耐磨性能差、使用寿命短、喷嘴易堵塞的问题，因此水煤浆的推广和应用受到了很大的限制。

The change of zeta potential of coal water slurry before and after ultrasonic irradiation was investigated.

在工业应用中，水煤浆不仅要有较高的浓度和较低的表观粘度，而且要有良好的流变性能和长时间的稳定性，良好的流变性和长时间稳定性有利于水煤浆的储存、运输、管道输送、雾化及燃烧[1] 。

Combined with Laohugou tunnel project and according to the different underground water yielding,it builds the different sealing batholite ,finishes the water stopping by using purdah injecting,and stops the leakage of the underground water,and this supplies theoretical reference and practical experiences to further extend the technique.

结合老虎沟隧道工程，根据不同的地下出水情况，成功地建造了不同的止浆岩盘，运用帷幕注浆完成了隧道的堵水工作，制止了地下水的流失，为进一步推广这一技术提供了理论参考和实践经验。

Weed species which appeared Over 20% in plots of golf courses were Cyperus rotundus,Kyllinga brevifolia,Oxalis dellenii,Panicum repens,Eleusina indica,Paspalum conjugtum,Digitaria sanguinalis,Hydrocotyle s...

在 2 0 %以上的样带小样方中出现的杂草种类为13种，即香附子、水蜈蚣、黄花酢浆草、铺地黎、牛筋草、两耳草、马唐草、天胡荽、狗尾草、空心莲子草、马齿苋、鸡眼草和犁头草；13种主要杂草总的年消长动态是：1～ 3月份个体数量较少，4～ 10月份期间生长加快，但消长起伏不平，10月份后变缓；70 %以上的主要杂草在草坪-杂草群落中生态位宽度均在 0 。7左右，其中生态位宽度较高的杂草种类为香附子(0 。90 5 4 )、水蜈蚣(0 。86 18)和黄花酢浆草(0 。8381)，生态位最小的杂草种类为马齿苋(0 。392 2 )；13种杂草中，相似性指数最高的杂草种对为空心莲子草与马齿苋(0 。75 98)，最小的杂草种对为天胡荽与鸡眼草 0 。16 6 6

It is noticeable that while w/c ranges from 3 to 5, long term strength of the grout increases significantly because of the existing of slag in the grout, i.e. while w/c are different, the grouts are affected differently because of the slag added to the grouts.

而值得注意的是添加炉石对於水灰比介於3-5之浆体的晚期强度提升有较明显之帮助，这也显示了在不同水灰比的情况下，添加炉石对浆体亦会产生不同程度之影响。

The strongly nonlinear pore structures of pulverized coals can be described by the fractal theory. The pore fractal dimensions of 10 pulverized coals, which are in the range of 2.572~2.722, were analyzed on a N2 adsorption porometer. The apparent viscosities of coal water slurries were measured on a Haake rotary viscometer.

用分形理论能描述具有强烈非线性特征的煤粉孔隙结构，利用氮吸附仪分析得到10种煤样的孔隙分形维数为2.572~2.722，利用Haake黏度计测量水煤浆黏度，讨论了孔隙分形、水分、氧量和可磨性指数等对水煤浆性质的影响规律，得到相关的拟合经验公式。

A suggestion is put forward to adding H2SO4 or (NH4)2SO4 into the mother liquor after calcium nitrate tetrahydrate separated for a further removal of residual Ca, thus the Ca content can be decreased to 0.35% from the previous 3.4%, and the viscosity of neutralized slurry to 0.04 ～0.08 Pa·s, with nice fluidity of slurry Water soluble phosphorus accoun ts to 88%～90%, and the process improves the adaptability of phosphate rock to nitrophosphate production.

提出分离四水硝酸钙后的母液加入H2SO4或(NH4)2SO4进一步除去母液中残钙，可使母液中钙含量由3.4%降到0.35%以下，中和器中料浆粘度可降到0.04～0.08 Pa·s，料浆流动性很好，产品中磷的水溶率可达88%～90%，并提高了硝酸磷肥生产对磷矿的适应能力。

The experimental results show that the maximum slurrying concentration of anthracite coal CWS is about 70%. Finally, based on the Fuzzing mathematics principles, it attempts to select the fuel characteristic together with the boiler running parameters to establish a new slagging propensity decision model. And it is combined with the running fact of WAN-FENG Power Plant, the results show that the model is more credible.

最后，针对电厂燃用水煤浆结渣的问题，采用模糊数学的判别方法，将燃料特性方面和锅炉运行方面的8个因素结合起来建立了水煤浆燃料结渣综合评判模型，并与电厂实际的运行结果进行对照，验证了该模型的准确程度。

I didn't watch TV last night, because it .

昨晚我没有看电视，因为电视机坏了。

Since this year, in a lot of villages of Beijing, TV of elevator liquid crystal was removed.

今年以来，在北京的很多小区里，电梯液晶电视被撤了下来。
