The break-even point of GKTT was recovered and a sensitivity analysis was conducted.

推算了广九直通车的上座率盈亏平衡点,并对其敏感性进行分析,认为票价P、定员总人数Q、固定成本F是其敏感性因素,在此基础上提出广九直通车产品策略宜实施“公交化”开行方案、特定时段增加密度或编组辆数、针对不同客流开行不同档次的列车;价格策略可采取溢价策略、特定时期票价上调、特定时段折扣、折让相结合的策略;应实施内部营销策略,以便降低固定成本,保证企业提供高质量的服务。

The operating costs of GKTT was resolved.

对广九直通车经营成本进行分解,并在实证分析基础上推算出广九直通车的上座率盈亏平衡点,进而对上座率盈亏平衡点进行了敏感性分析,认为票价、定员总人数、固定成本是其敏感性因素,并结合广九直通车运营现状给出广九直通车经营决策中的相关建议。

A simple and effective method is introduced to resist the jamming which often leads to shoot-through in HV switch power supplies.

高压开关电源易受干扰而造成直通,针对这种缺陷,本文提出了一种简单而有效的抗干扰方法,原电路只增加少量元器件就可彻底消除直通故障。

With a unique X-type Z-source network, Z-source inverter can utilize the shoot-through state to boost the output voltage as the two-stage dc-ac inverter, which provides an attractive single-stage dc-ac conversion.

Z-源逆变器由于采用独特的X型Z-源网络,可以利用逆变器桥臂直通状态实现升压功能,从而使单级Z-源逆变器具有与两级并网系统相类似的性能。
