In the different zoning of xenoliths, molybdenum and tungsten contents is lower and homogeneous,and be lower than the world\'s average abundance; tungsten compared to molybdenum,the content more homogeneous in xenoliths, compared to mantle\'s average abundance more less. This explains the geochemistry incompatible character homophyly and diversity of molybdenum and tungsten determined their trend enrichment in crust in the course of the mantle evolution and magmatism, among molybdenum more trend enrichment in lower crust but tungsten in middle-upper crust.
包体不同带中，钼、钨的含量较低且较为均一，并低于世界均匀丰度；钨和钼相比，其在包体中的含量更为均一，相对于地幔均匀丰度更小，说明钨、钼的地球化学不相容性的类似性和差异性决定了它们在地幔演化和岩浆过程中倾向富集于地壳中，其中钼更倾向富集于下地壳，钨则更倾向富集于中上地壳。

The deposit of tungsten and the output of tungsten concentrate in Ganzhou, each take 30% that of total in China. Among them the deposit of high grade wolframite takes as much as 70% that of total in China and 60% in the world. So Ganzhou is called as "Tungsten capital of the world".
而赣南地层中钨的富集为世界地层钨平均值1.33ppm的7倍以上，高达9.53—12ppm，钨矿储量及钨精矿的产量均占全国30%，其中高品质黑钨保有储量占全国同类矿的70%，世界的60%；于是赣州，成为誉满五洲的"世界钨都"。

The effects of the spray-drying process of the ammonium paratungstate and the carburization temperature on the formation of the precusor and WC powder were investigated.
采用喷雾干燥-固定床法制备碳化钨粉末，研究了喷雾干燥和碳化反应温度对制备偏钨酸铵前驱体以及碳化钨的影响，前驱体粉末呈现均匀的球状形态，平均粒径为10~20μm，喷雾温度对影响粒径大小和分布影响小；400℃的进口温度下进行喷雾干燥，喷雾粉末仍然保持偏钨酸铵原来的基本组成不发生分解。

The weight loss rate in 600 ℃ sodium containing 30 μg/g oxygen is about 1×10~(-4) mm·a~(-1) and 2×10~(-4 mm·a~(-1), respectively for the rotary swaging tungsten and polishing tungsten.
在600℃、含30μg/g氧的金属钠中，旋锻钨和抛光钨的失重速率分别为1×10-4mm·a-1和2×10-4mm·a-1，两种钨与钠均有良好的相容性。

It was shown by further research that the formed tungsten oxide had an obvious layer-like structure, where from outer to inner layer the valence of tungsten increased and the reduction degree decreased. The carbonization of W depended on the replacement of W atom at the center of the body-centered cubic by C atom and the minor adjustment of C atom position and the lattice parameters.
深入研究表明，氧化钨碳还原颗粒具有明显的层状结构，自外到内钨的化合价递增，还原程度降低；钨的碳化是碳原子替换体心立方钨晶胞的中心钨原子，然后碳原子转换到钨原子点阵间隙再经晶胞常数微调而形成。
