In practice, available cash is essentially operating cash flow less cash interest expense and less maintenance capital expenditures.

实际上，可支配的现金其实就是经营性现金流减去现金的利息支出、以及现金维护开支。

Though any positive number is OK, it's best if the operating cash flow exceeds the net income (top line) for the same period.

虽然任何正值都是好的，但如果经营性现金流在同一时期超过净收入（在表的第一行）是最好的。

Comparing amount of cash generated to outstanding debt, known as the operating cash flow ratio, illustrates the company's ability to service its loans and interest payments.

把已创造现金数额与未偿还债务作比较，也就是经营现金流比可以说明该公司偿债付息的能力。
