The corresponding network traffic simulating model of tubule obtains the corresponding adjustment flow of each liquid separation capillary, and respectively by each point
The initial flow of liquid capillary is adjusted to corresponding adjustment flow.
Further, terminal is based on each after the initial flow respectively to each liquid separation capillary is adjusted
The corresponding network traffic simulating model of liquid separation capillary and each corresponding liquid separation capillary initial flow adjusted, obtain respectively
The corresponding inlet outlet pressure differential adjusted of each liquid separation capillary.

Wipe parameter, wherein friction parameter initial flow corresponding with a liquid separation capillary is positively correlated, and respectively with one point
The corresponding cross-sectional area of liquid capillary, Access-Point Density and gradient pressure drop are negatively correlated；
Based on the friction parameter, the network traffic simulating model of one liquid separation capillary is determined.
7. such as device described in claim 5 or 6, which is characterized in that determining the inlet outlet pressure differential of each liquid separation capillary not
When identical, based on the inlet outlet pressure differential of any one liquid separation capillary, respectively to the initial flow of each liquid separation capillary
When amount is adjusted, the adjustment unit is specifically used for:
When determining that the inlet outlet pressure differential of each liquid separation capillary is not exactly the same, the inlet and outlet of any one liquid separation capillary are selected
Pressure difference, as adjustment pressure difference；
Based on the adjustment pressure difference, each corresponding network traffic simulating model of liquid separation capillary is respectively adopted, obtains each point
The corresponding adjustment flow of liquid capillary；
The initial flow of each liquid separation capillary is adjusted to corresponding adjustment flow respectively.
8. such as device described in claim 5 or 6, which is characterized in that determining the inlet outlet pressure differential of each liquid separation capillary not
When identical, based on the inlet outlet pressure differential of any one liquid separation capillary, respectively to the initial flow of each liquid separation capillary
After amount is adjusted, the adjustment unit is also used to:
After each corresponding network traffic simulating model of liquid separation capillary and corresponding each liquid separation capillary adjustment
Initial flow, obtain the corresponding inlet outlet pressure differential adjusted of each liquid separation capillary respectively；
When determining that each liquid separation capillary inlet outlet pressure differential adjusted is not exactly the same, based in addition to any one described liquid separation
Any one other liquid separation capillary inlet outlet pressure differential adjusted except capillary, respectively to each liquid separation capillary
Initial flow is adjusted again.
