利用超音速射流分散纳米粒子的新型湿式粉碎机(中文2900字,英文1800字)
概要
    我们已经检查并且探讨了分散纳米钛酸钡（BT-NPS）的技术和实验过程，在这其中通过使用新颖的超音速射流（SSJM）新型湿式粉碎机上的分散体上的喷嘴，讨论、研究出了空气压力对其的影响。本次研究的这款新型湿式粉碎，是机利用超音速射流（SSJM），粉碎纳米粒子的。初步得出聚合粒子的大小与空气压力和碰撞时间的关系，得出其随后两者的增加而相应的增加。在实验过程中，在优化条件下，BT-纳米颗粒几乎与初级粒子一样分散离合。但是，经过一段时间的进一步碰撞，最终的过度碰撞造成了物质间的相互重新组合。这种挤压破坏、重新聚合的现象以及分散程度受到空气压力的影响。注入的液滴形成了直径几乎相同的形状，速度随着空气压力的增加而增加，最终增加到了300m/。通过此类现象的研究，我们纷纷猜测，在引起这些一些列的现象中，冲击波在BT-粒子的分散中占据了主导地位，起到了推波助澜的作用。

Dispersion of nanoparticles by novel wet-type pulverizer utilized supersonic jet flow
Abstract.We have examined the dispersion of barium titanate nanoparticles (BT-NPs) and
have discussed the effect of air pressure supplied to the nozzle on the dispersion by using novel
wet-type pulverizer utilized supersonic jet flow (SSJM). The aggregated particle size was
decreased with increasing the air pressure and the collision times. In the optimized condition,
almost the BT-NPs were dispersed with the primary particles, however, further excessive
collision had caused reaggregations. The degree of dispersion has been affected by the air
pressure. The injected droplets had formed almost the same diameter regardless of air pressure
and the velocity was increased with increasing of the air pressure and reached 300 m/s. We
have speculated that the shockwave dominates the dispersion of BT-NPs.
