ballast resistance

By many years experiences, controlling ballast resistance and excessive compressive temperature force of the rail is recognized as the only means to overcome the track buckling.

多年来认为控制道床阻力及钢轨内的温度力是防止胀轨跑道的主要办法。

The stability conditions of multipin-to-plate discharge of transverse discharge excited CW CO2 laser have been analysed. The dependence of the discharge stability on the series ballast resistance and tne application of stable current regulator are discussed.

本文分析了多针对平板放电、横向电激励CO2激光器的稳定性条件，论述了放电稳定性与镇流电阻的关系，以及稳流调节器的应用。

But in fact, due to the great variation of ballast resistance during track work and change of "stress free temperature" of the rail, they are hard to measure then hard to control.

但道床阻力在作业时变化很大，钢轨在线路上长期使用，锁定轨温可能发生变化，温度力亦不易控制。
