本公司生产的轻烧氧化镁系选用一级菱镁矿石，采用科学的烧结技术，经轻烧反射窑、回转窑或沸腾炉煅烧而成，严格控制烧失量，产品煅烧均匀，为无定形粉末、无臭、无味、无毒。

Spinels were enriched by compounds of magnesia and alumina.

尖晶石丰富了镁和氧化铝化合物。

Spinels were enriched by compounds of magnesia and alumina.

尖晶石化合物丰富了镁和氧化铝。

Spinel is a compound of magnesia and alumina(Al2O3) and is thus a magnesium aluminate(MgAl2O4), found as accessories in igneous rocks, in metamorphosed aluminous schists, in contact metamorphosed limestones and sometimes in high temperature iore veins.

尖晶石主要成分是氧化镁和氧化铝，结晶习性是等轴晶系漂亮的正八面体。镁被铁置换就是铁尖晶石，被锌置换就是锌尖晶石，铁完全置换镁形成磁铁矿，铬置换铁尖晶石形成铬铁矿，这些类质同相的等轴晶系都是八面体结晶的尖晶石族矿物。

The industrial magnesia and vitriol are used to produce magnesium sulfate in this paper, and the simulated wastewater is prepared using magnesium sulfate and kaolin. The flocculating effect of polyacrylamide, cationic polyacrylamide and anionic polyacrylamide is studied and compared through measurement of absorbency by spectrophotometer.

利用工业氧化镁和硫酸制备一定浓度的硫酸镁，结合高岭土配制氧化镁烟气脱硫的模拟废水，通过分光光度计吸光度测定了聚丙烯酰胺、阳离子型聚丙烯酰胺和阴离子型聚丙烯酰胺在模拟废水中的絮凝效果。

After raw materials modified and prescription optimized,a kind of heatresistant toughened strain adhesives ZT1 which were mostly composed of phosphate inorganic adhesives were developed. Improving preparation technology of aluminum dihydro phosphate to increase polymerization degree and treatment technology of magnesia to increase surface activity,and adjusting with all compositions,the molecular bond nets of inorganic adhesives were renovated and perfected.

以耐温性优异的磷酸盐类无机粘合剂为主体材料，通过改进絮凝剂磷酸二氢铝的制备工艺提高其聚合程度，以及改善固化剂氧化镁的处理工艺提高其表面活性等手段，进行原材料改性，并结合配方优化，实现了无机粘合剂键合网络的修复和完善，研制出了耐高温韧性应变胶ZT1。

Inhibitors are added in the green sand mold to avoid the moisture from reacting with the magnesium melt, resulting in forming magnesia slag and hydrogen formation.

故而本实验将比较使用不同的抑制剂，包括十二烷基磺酸钠、硼酸、硫磺、与氟硼酸钾等对於AZ91镁合金铸件外观之研究。

Cynanchum Lingtai apricot production in the average weight 65 grams, the brightly-colored fruit, juicy rich, sweet-sour taste, sweet from the nucleolus, when the late Qing Dynasty famous Shaanxi, Gansu provinces, the Qing imperial court Tongzhi tribute for years.

灵台生产的牛心杏平均单果重65克，果实色泽鲜艳，汁多味浓，甜酸适口，离核仁甜，清末时就驰名陕、甘两省，清同治年间曾为朝廷贡品。

Chenopodium album,Solanum nigrum, and Amaranthus retroflexus were very susceptible to the herbicides. Polygonum persicaria and Abutilon theophrasti were relatively less susceptible to the herbicides, and Lycopersicon esculentum was not susceptible to it. The relationship between reduction rates of weed biomass and PPM values of weed leaves 2,4, and 6 days after treatment was established.

供试的6种杂草对该混剂的敏感性存在显著差异：红心藜Chenopodium album、龙葵Solanum nigrum和反枝苋Amaranthus retroflexus对该混剂最敏感，ED90值分别为47.65、71.67和29.17g/hm2；春蓼Polygonum persicaria和苘麻Abutilon theophrasti敏感，ED90值分别为96.91、114.20g/hm2；而番茄不敏感。
