玉球

探讨了以刚玉球为载体，V2O5-TiO2为活性组份的邻二甲苯氧化制苯酐催化剂活性下降原因。

The cause for reduction in activity of the catalyst with V_2O_5-TiO_2 as the active component for oxidation of o-xylene to phthalic anhydride was investigated .

刚玉球层埋深相同，但刚玉球直径不同时（分别为7mm、14mm），加入φ14mm刚玉球的靶体，其抗侵彻性能更好；

While the corundum spheres in the same depth , but their diameters are different , the anti-penetration characteristics of the targets with φ 14 mm spheres is in evidence better than that of the targets with φ 7 mm spheres .

邪恶之神被关在一个玉球里。

The evil is imprisoned in the Ganzi jade globe .

刚玉球层的位置和弹体与刚玉球的碰撞角度对弹体的侵彻深度有较大影响。

The location and the position of the corundum spheres are important for anti-penetration ability .

实验还表明，刚玉球表面曲率的大小对靶体的抗侵彻性能有较大作用。

We also prove that the diameter of the corundum sphere is important for anti-penetration ability .
