基本循环 meaning in Chinese

basic cycle
basic loop

Basic recurrence process and its information measure of information
信息的基本循环过程及其测度研究
The conclusion is that if an appropriate refrigerant mixture is used , the lhr cycle can have a relatively higher thermodynamic efficiency than that of basic cycle , in case their pressure ratios are the same . the thermodynamic efficiency can be further improved when the acr cycle is used
研究结果表明，正确地选择混合工质，在相同的压比下，可使lhr循环比基本循环具有更高的热力学效率，而采用acr循环可以较lhr循环更进一步提高循环的热力学效率。
