Thixotropy of peptized concentrated aqueous pseudo-boehmite suspensions of SD and TY was performed with different methods including hysteresis loop and steady shear measurements.

采用经典的滞后环方法和恒剪切速率方法分别考察了山东工业拟薄水铝石和实验室自制拟薄水铝石胶溶所形成的浓水溶性悬浮体系的触变性。

Pseudo-boehmite was prepared with nitric acid and sodium aluminate under the same precipitation conditions but different ageing and washing conditions. The influences of ageing temperature, ageing time and ageing media were studied. It was shown that pronging the ageing time and increasing temperature lead to improve crystallinity of PB., the pore diameter of PB can be increased after NH4HCO3 is added in the ageing medium.

在相同成胶条件下利用铝酸钠溶液和硝酸制备拟薄水铝石，而在不同条件下进行老化，研究了老化温度、老化时间及老化介质的影响，结果表明延长老化时间、提高老化温度和老化pH值有助于结晶度的提高，使用NH4HCO3等具有扩孔作用的溶液作为老化介质会降低产品的堆密度和增加孔径、孔容、比表面积。

To correct the variation resulting from exposure condition, an aluminum stepwedge was exposed simultaneously. By referring the image of aluminum stepwedge on each radiograph the equivalent aluminum thickness and corrected gray level intensity of the ROIs could be calculated as indicators of alveolar bone density. Nineteen specimens containing different amounts of hydroxy-phosphorite were radiographed.

用计算机测量定位投照的直接数字化牙片上感兴趣区(region of interest， ROI)的灰度，拍片时将一个铝制梯级同时曝光，根据已知的铝梯灰度和厚度推算ROI区灰度所对应的等效铝厚度和校正灰度来反映骨密度，从而校正由于投照条件差异造成的灰度误差。

Shall clean recessing and printing places' aluminum scrap or sharp edges when processing the toothed aluminum bracket and ensure a good match with washer.

4.2.15有牙铝码加工时切除位或啤孔位铝屑或批锋清理干净，保证与有牙介子之间的正常配合，注意啤长孔可能导致的变形。

The scientists looked at aluminum smelters, which are giant current sinks, and came up with a small battery made from antimony and magnesium sandwiching an electrolyte.

科学家们把研究的目标定位在铝冶炼厂上，铝冶炼厂一般用电量都很大，经过研究他们发明了以锑、夹有电解质的镁为原料制成的小电池。

Root border cells are recently defined alive population sloughed from root tips and loosely adhered in the water soluble mucilage, and the root tip is just the target of Al toxicity, thus it was guessed that border cells might function crucially in the response to Al toxicity.

根边缘细胞是从根冠游离并聚集在根尖周围的一群特殊细胞，铝毒的作用部位正是根尖，因此推测边缘细胞在铝毒反应中起着重要作用。

Root border cells are recently defined alive population sloughed from root tips and loosely adhered in the water soluble mucilage, and the root tip is just the target of Al toxicity, thus it was guessed that border cells might function crucially in the response to Al toxicity.

根边缘细胞是从根尖脱落下来并聚集在根尖周围的一群特殊的细胞，在根际周围起着至关重要的作用，国内外研究表明铝毒对植物影响最快的部位是根尖，而根边缘细胞在根尖产生并聚集根尖周围，因此推测根边缘细胞在根对铝毒响应中起重要作用。

The present invention is suitable for aluminum casting requiring high antiwear property and Al-Si alloy with smelted waste material.

本发明适用于要求耐磨性高的铝铸件，以及熔化大量废、旧零件以及切屑的铝硅合金。

Bauxite is aluminium ore which is smelted into alumina and then refined into aluminium.

铝土矿是一种铝矿石，经冶炼可加工成氧化铝，而氧化铝在经精练加工成铝。

Then the aluminium sulfates were prepared by sulfation and salt formation, and their IR spectra were analyzed.

对制得的几种碱式铝盐进行了红外光谱分析和有机硫含量、铝含量及样品制酸力等部分理化性质的测定。
