Table 1
To choosing the total and different cutting scheme of different collection and use in the above method The time of different computational methods consumption contrasts as follows respectively:
(1) in order to show algorithm involved in the present invention for the virtual lump involved by lumped model The dependence of component number, is calculated with the lump of 20 lump 50 and 100 lumped models respectively herein The distribution curve of related fraction oil quality point rate data, and result of calculation is entered with experimental result Row contrast, comparing result is listed in shown in Fig. 9, and X-coordinate represents fraction oil cutting temperature/take the photograph Family name's degree, Y-coordinate represents fraction oil quality point rate data.
Result of calculation shows that lump component number is intended for the calculating of product fraction oil quality point rate Close quite important.If it is desired to reaching fitting precision higher must assure that enough virtual group numbers Amount.When virtual component is 20, result of calculation is very coarse to express product fraction oil The general trend of amount point rate data, but product fraction oil quality point rate data cannot be given expression to completely Distribution detailed information, no matter high boiling range fraction namely the virtual lump group of mean boiling point highest Part fraction oil quality point rate data or low boiling journey fraction namely minimum virtual of mean boiling point The fraction oil quality point rate data of lump component are not always the case;When virtual component is 50, meter Calculate result preferable for what the distribution of the fraction oil quality point rate data of high boiling range fraction coincide, this Because fluctuation of the distribution of the fraction oil quality of high boiling range fraction point rate data with cutting temperature It is smaller, and model for the distribution and expression of the fraction oil quality point rate data of low boiling journey fraction compared with It is coarse, because the distribution of the fraction oil quality of low boiling journey fraction point rate data is with the ripple of cutting temperature It is dynamic larger;When virtual component is 100, fraction oil of the result of calculation for height boiling range fraction It is preferable that the distribution of mass fraction data coincide, and had both reflected the fraction oil of high boiling range fraction The gentle distribution of amount point rate data, is also demonstrated by the fraction oil quality point rate data of low boiling journey fraction Fluctuation distribution.
