Low in V

In the design of classical V-belt driving, the traditional method has disadvantages of low efficiency and the great work load of looking up manual. In addition, its design may not be the best.

在普通V带传动设计中，传统设计方法存在查找手册工作量大、效率低的不足，且所得设计方案未必是最佳设计方案。

Objective to investigate the characteristics and mechanism of low volume and regular pressure volume (P-V) curves in acute respiratory distress syndrome (ARDS) dogs.

目的研究急性呼吸窘迫综合征(ARDS)犬低容积段及常规压力-容积(P - V)曲线的特征，并探讨其产生机制。

It can achieve a fixed output of DC voltage in the universal input range of ac 80 ~ 265 V. It owns the advantages of high efficiency, low total harmonic distortion, PF near to 1.

该方案能在80 ~ 265 V宽输入电压范围内得到稳定直流电压输出，具有效率高、总谐波畸变率低、功率因数接近为1等特点。
