The three layer microstructure model image of W particle inner alloy was established.

建立了合金中W颗粒的三层微观结构模型。

The scatter of WC grain fineness is referred to the fineness homogeneity of raw material W particle and the fineness of grain is influenced by the surface perfectness for thick W pattiel- es.

WC晶粒度的分散性与原始W颗粒度的均匀性有关，对于粗W粉，其颗粒完整性对WC的晶粒度有影响；

DASB can remove the organic particle by its short-time anaerobic technology, thus preventing W-SFCW from jamming and affording enough carbon for denitrification.

DASB单元采用短时厌氧技术，去除颗粒有机物和部分溶解有机物，防止W - SFCW堵塞，保证W - SFCW单元脱氮所需的碳源。

Results show that simple composition and stable properties of W oxide is a prerequisite for quality WC powder with uniform particle size and less aggregate.

结果表明：保证原料氧化钨相成分单一和性能稳定是生产粒度均匀、聚团少的优质WC粉的前提；

After receiving this news in the summer of 1912 in Leeds, W. H. Bragg tried to explain it by the particle theory of X-rays, while his son w.

老布拉格在1912年夏得知这个消息，与他儿子小布拉格一道尝试用X射线的粒子性解释它，并由小布拉格在剑桥大学重复这个实验。
