The inverse phase suspension polymn.
介绍了合成增稠剂SKT的逆相悬浮聚合工艺及单体配比、交联剂用量、引发剂用量等影响因素,确定了合成增稠剂SKT的最佳工艺条件。
Long life cycle adverse wind regions in Doppler radial velocity images were observed during the snowstorm.
结果表明:这次暴雪发生在西北气流、较大海气温差和半岛的丘陵地形特殊条件下;冷流暴雪在多普勒天气雷达径向速度图上表现为长生命史的逆风区。
The sandstorm occurred in the weak echo area which was in front of the strong echo and in the adverse wind region of radial velocity.
结果表明:高空冷空气快速东移叠加到地面热低压之上形成对流不稳定,使得中尺度对流系统快速发展;T-LnP图上500~540 hPa干暖盖有利于对流层低层不稳定能量的存储和积累,干暖盖是强对流天气发生的重要征兆;沙尘暴发生前对流系统先从低层发展,然后迅速向中层发展;沙尘暴发生后中低层雷达回波减弱;中层回波开始增强,并向下发展,降水增大后,沙尘暴减弱消失;沙尘暴发生在紧邻强回波前面弱回波区域内;地面观测沙尘暴发生、发展、消亡时间与逆风区生消演变密切相关,沙尘天气发生在逆风区范围内,强沙尘暴天气发生在逆风区外层风速大值区的强辐合上升气流中。
Results show that the warm advection convergence, close zero velocity field and adverse wind area which appear successively during the snowstorm are the main character of Doppler velocity.
结果表明:降雪开始后相继出现的暖平流辐合、闭合零速度区和逆风区是本次暴雪天气过程多普勒速度的主要特征;持续的垂直风向切变及强辐合等风场结构为暴雪产生创造了条件;低空东南气流对多普勒速度特征的形成及暴雪的产生起了主导作用。
