天然气P－V－T性质的Lee－Kesler法电算

Computerization of P-V-T Propenies of Natural Gas by Lee-Kesler Method

Ｌｅｅ－Ｋｅｓｌｅｒ查图法计算天然气Ｐ－Ｖ－Ｔ性质．准确度高、应用普遍，但只便于手算。将算图描样点转化为数据表，并采用二元三点插值，可使该法计算机化，其计算精度能满足要求。

Calculation of natural gas P-V--T properties by Lee-Kesler graphic method phigh accuracy and is univenslly used font it is only convenient for manual calculation. By conveningthe sampling Points on nomograph curves into data ambles,and using dual-element three-point interpolation,this calculation method can be computered,and the calculation precision can meet the requirements.
