机车乘务员现状与有效培训

铁路提速以及牵引机型的转变已有几年,但工学矛盾的突出阻碍着铁路的发展,培训手段及设施的落后使机车乘务员素质的提高落后于技术、设备更新的速度。只有解决了预备率、竞争机制等一系列问题,才能从根本上解决机车乘务员培训的有效性,这是摆在机务教育工作者亟待思考的问题。

南宁南车辆段人力资源管理的难点及建议

针对南宁南车辆段在人力资源管理方面存在的四大难点问题，本着以人为本、人性化和和谐管理的理念，提出加强对“泡病假”职工的教育与关心，建立正常的人员招录制度，老病残弱职工不占定员指标，提高定员预备率等4点建议，以利劳动关系的和谐，促进安全生产。

Analysis on Application of Wavelet Neural Network in Wind Electricity Power Prediction

Wind electricity power has fluctuation, and accurate and reasonable wind electricity power prediction is very important for solving wind electricity network and combination. This paper takes an analysis of a lot of actual data of a certain wind electricity field. Through wavelet neural network and time series method rolling, it can predict the overall power of wind electricity field. The result shows that for the original data of sampling time length and large sampling frequency, the model constructed by this paper has very good prediction effect. Because of the fan installation position, wind electricity fan flow effect and other random factor influence, wind electricity field overall power and single unit power distribution have difference. Through comparing with the time series parameters, it puts forward that single wind electricity unit power has smooth effect for overall power of wind electricity field. Finally, it summarizes the prediction effect and puts forward some reasonable suzestions for wind electricity network troblems.

3种根管治疗器械根管再治疗的临床效果比较

目的:探讨3种根管治疗器械根管再治疗的临床效果。方法:纳入2016年11月~2018年12月本院诊治的42例因根管填充不实或者欠填、需要进行根管再治疗者作研究对象,应用TF根管锉者设为TF组(n=14)、应用Pro Taper D再治疗系统者设为Pro Taper D组(n=14)、应用不锈钢锉治疗者设为不锈钢锉组(n=14),对比3组患者预备后无痛率、预备时间。结果:(1)TF组短于Pro Taper D组,Pro Taper D组短于不锈钢锉组(t=16.425,25.660,P<0.05);(2) TF组预备后无痛率低于Pro Taper D组、不锈钢锉组(χ^2=5.250,5.169,P<0.05)。结论:TF根管锉用于根管再治疗中,可缓解患者疼痛感,且能节省用时。
