Preliminary Study on Application of Ultrasonography in the Transverse Cervical Artery;
颈横动脉超声检测方法的初步研究
The influnce of lateral play of locomotives wheelset on many issues;
机车轮对横动量对若干问题的影响
The calculation shows that Ⅰ-end achieves better geometric curve negociation than Ⅱ-end at front position, the lateral play of middle bogie single side gap is designed at 200 mm, which is bigger than when Ⅰ-end is at front,min 180 mm, but smaller than when Ⅱ-end is at front,min 205 mm.
