查询词典 powder metallurgy

A uniform mixture of silicon powder (granularity≤0.044 mm) and polyvinyl alcohol solution (PVA,5 wt%) in response to a certain proportion was prepared.After sieving,prilling and vibration,the mixture was packed.Effects of the vibration frequency (14～50 Hz) and time (10~230 s) on packed density of powder were studied.

For dense grade the saturated-surface-dry method is more correct than the wax-enveloped method if fully soaped. For loose one, the latter is more correct than the former if the wax is not shed and the temperature is not too high. For sample with some holes, covered with talcum powder will be more correct, thus the talcum powder should be required for these ones, and the calculating formula should be amended referring to this paper.

研究结果表明，密级配试件表干法比蜡封法更趋准确，但试件应充分浸水；对于开级配试件，蜡封法结果比表干法更为准确，但要保证水不会由于蜡的脱落而进入试件，同时温度不宜过高；对于表面坑洞较多的试件，加滑石粉可以替代试件的开口空隙而使结果更加准确，故对沥青碎石试件最好强制添加滑石粉，而且计算公式应参考本文推荐公式进行修正。

Ultra-micro powder property and mechanism is discussed. The influence of volatilized silica and α-Al2O3 micro-powder on refractory casting performance such as watering, formation, strength and slag resistance are also discussed here.

论述了超微粉的性能及作用机理，讨论了硅灰和α-Al2O3微粉对耐火浇注料加水量、成型性能、强度和抗渣性能的影响。

These are simply a mixture of detergent powder with enzyme powder ....

这些不过是洗衣粉和酶的一个简单的混合物。

Results show that acid value of carboxylic wood powder from alkaline hydrolysis is higher,but its yield is lower than that from acid hydrolysis. The adsorption capacity of carboxylic wood powder for basic pink dye increased with increase of the initial concentration of the adsorbate,and could be kept over 500mg/g after repeated use and regeneration for 4 times.

实验结果表明：（1）在适量引发剂（FeSO4 * 7H2O=1g）和适当温度（60℃）作用下，可得到较高接枝增量和接枝率的PANW；（2）在PANW的水解反应中，在碱性催化剂作用下，可得到羧基含量高的产物，但收率较低；而在酸性催化剂作用下，则得到羧基含量低的产物，但收率较高；（3）羧基木粉对阳离子型染料--碱性桃红的吸附容量与起始浓度有关，本实验中，羧基木粉对碱性桃红的吸附容量最高可达500mg/g，对Cu2+的吸附容量最高可达39mg/g；（4）经0.3mol/LHCl再生4次后，羧基木粉对碱性桃红的吸附容量保持在440mg/g以上，在含有多种金属离子的溶液中，羧基木粉优先吸附Fe3+等硬酸型离子。

Aiming at the currently shortage of XML streams quality detecting, this paper proposes a new forecasting method of XML streams quality by least squares support vector machines, which is used the method of XML keys' vector matrix as windows, and vector product wavelet transform to multilevel decompose and refactor the XML streams series, that can fulfill real-time checking demand of XML quality, and ensure constraint, consist- ency and integrality. For even more adapting net load, it proposes a control strategy by weight and adaptive adjustment to ensure XML streams quality.

针对当前XML数据流质量检测存在的不足，提出构建XML键的矢量矩阵作为窗口，利用矢量积小波变换多级分解与重构XML数据流，再结合最小二乘支持向量机对XML数据流质量进行预测的一种方法，满足XML数据流质量重构时实时检测的要求，保证XML数据的约束性、一致性与完整性；为了更好的适应网络负载，采取加权与自适应窗口调整等调度策略充分保证XML数据流的质量检测。
