The invention relates to a method for determining a step-by-step speed limit value of an exit ramp of a freeway, belonging to the field of traffic operation management of the freeway. The method comprises the following steps: dividing a speed characteristic value of the exit ramp into three site vehicle speeds, including a ramp nose end part, a transition section starting point and a reasonable outer side mainline of an exit ramp upstream section, through a research on running vehicle speed and deceleration of the exit ramp upstream section; deducing a running speed of the transition section starting point according to a ramp nose end speed limit value, continuously deducing a vehicle speed of the reasonable outer side mainline lane, combining an investigated or predicted mainline vehicle running speed to acquire a speed limit value calculation model and a corresponding calculation formula, finally determining a final step-by-step speed limit value according to engineering experience. Based on verification results of the method disclosed by the invention in combination with examples, the method disclosed by the invention has the advantages of simple and convenient calculation, high precision, suitability for engineering practical application and the like, effectively solves the shortcomings of the prior art and can be widely applied to the traffic operation management of the freeway.

The invention provides a method and kit for guiding administration of verapamil by simultaneously detecting multiple loci related to the metabolism of the antihypertensive drug verapamil through matrix-assisted laser desorption ionization time-of-flight mass spectrometry (MALDI-TOF MS) because different single nucleotide polymorphism (SNP) loci have extension primers with different molecular weights. The method includes the following steps: designing multiple amplification primers and extension primers according to eight target SNP loci to be detected; preparing a multiple amplification primerreaction system and an extension primer reaction system; in the reaction systems, simultaneously performing amplification and single-base extension reactions on the eight target SNP loci by using multiple sets of primers; and performing time-of-flight mass spectrometry analysis on the products after the single-base extension reactions, and identifying the genotypes of different drug metabolism-related SNP loci according to the products of different-molecular-weight extension primers represented by mass spectrum peaks to guide the administration of the antihypertensive drug verapamil. At the same time, the invention provides the detection kit using the method. The method can simultaneously detect the eight SNP loci related to the metabolism of the antihypertensive drug verapamil, and has the advantages of low costs, no need for synthesis of probes, short time consumption, simple and convenient result analysis, and extremely wide application fields.
