rare earth addition

The recrystallization temperature and the strenth of molybdenum thermionic cathode wires are increased greatly by addition of about 4wt% content of rare earth oxides.

4wt%左右稀土氧化物的加入，能显著提高钼热阴极丝材的再结晶温度和室温抗拉强度。

The dislocation microstructures in the tensile specimen of aluminium lithium alloys 2090 with addition of minor rare earth element cerium ( 2090+ Ce) were investigated by means of TEM ( electron transmission microscopy).

本工作利用TEM技术对添加微量稀土铈的2090铝锂合金（2090+Ce）拉伸试样中位错组态进行了观察。

In addition, the sintering mechanism of tin dioxide ceramics doped with rare earth elements was analyzed in detailed.

本文还详细分析了稀土元素掺杂二氧化锡陶瓷的烧结机理。

Results show that the dyeings using natural dyestuff with rare earth as mordant feature enhanced dye depth and color fastness. In addition, the optimum conditions for cotton pad dyeing using rare earth as mordant were defined.

结果表明，采用稀土媒染轧染工艺效果较好，文中给出了天然染料用稀土媒染棉织物的染色工艺条件。结果：酶切、PCR及测序鉴定证实，pAd。

The effect is specially obvious with the addition of Ce-rich rare earth.

添加 富铈 稀土和铬合金元素的锯片胎体耐磨性都有提高,其中添加富铈稀土效果尤为明显.
