热力学模型参数关联时，BIP 设定。help 文档
You can load BIP data into your user database via the neutral file.  The format of each BIP line is:

BIP        type        sec-ID        BIP-A, [BIP-B, BIP-C, BIP-D, etc]

The BIP type must be one of the following:
       NRTL
       PR (Peng-Robinson)
       SRK (Soave-Redlich-Kwong)
       UNIQUAC
       WILSON
       BWRS
       ESD
       SAFT
Valid names are listed in the BIPNAMES.SF file in the system directory.
The BIP sec-ID is the secondary ID for this BIP data. Associated with each set of BIP values are, of course, two components; the primary component and the secondary component. The BIP keyword must be included somewhere between a pair of STRC and ENDC keywords. The STRC and ENDC keywords define a group of lines pertaining to the same component and it is assumed that this component is the primary component. The BIP sec-ID is the secondary ID associated with this BIP data and is the CHEMCAD ID number for the secondary component.  You can specify any secondary ID so long as it is numerically less than the primary ID. For example, the following BIP line specifies values for WILSON BIPs between a user-added component and water (CHEMCAD ID for water is 62).

BIP        WILSON        62        -52.605        620.63

If the current group of lines in your neutral file pertains to component 8001 and you include the following line in this group, it would be discarded because the secondary ID is greater than the primary ID:

BIP        WILSON        8005        -52.605        620.63                [invalid data]

The order in which you specify the BIP parameters is important. You must specify at least one BIP parameter. The maximum number of parameters depends on which BIP type you are specifying.
The BIPNAMES.SF file in the system directory includes the maximum number of parameters that can be specified for each BIP type. The order in which you specify BIP parameters is also important. The following list indicates the correct ordering for each BIP type:

BIP        NRTL                secID        Bij, Bji, alphaIJ, Aij, Aji                        [maximum of 5 parameters]
BIP        PR                secID        Bij                                        [1 parameter only]
BIP        SRK                secID        Bij                                        [1 parameter only]
BIP        UNIQUAC        secID        Aij, Aji, Uij, Uji                                [maximum of 4 parameters]
BIP        WILSON        secID        Aij, Aji                                        [maximum of 2  parameters]
BIP        BWRS                secID        Kij                                        [1 parameter only]
BIP        ESD                secID        Kij, KTij, KaLin, dHLin, KaBin, dHBin        [maximum of 6 parameters]
BIP        SAFT                secID        Kij, KTij, KaLin, dHLin, KaBin, dHBin        [maximum of 6 parameters]
