This technique is feasible to reduce production costs and step up production in order to meet the high performance needs of ratio superficial area and purity.
为满足特种纳米粉高比表面积和高纯度的性能指标制备要求，降低成本和实现大量生产提供了一种较为可行的技术方法。
Conversely, step-down ratio insufficiency is compensated for by making the switching frequency during the step-down operation lower than the switching frequency during the step-up operation.
反之，通过根据升压时的开关频率来降低降压时的开关频率，可弥补 降压比的不足部分。
