Abstract: A discharging container comprising a container body that stores a content and a discharging component that discharges the content. The discharging component comprises a cover portion mounted to a mouth neck portion of the container body and a pump head portion that discharges the content by a pressing operation. A tubular guide rod is erected upwards from the periphery of an opening formed in the central portion of a top plate of the cover portion. The pump head portion is provided with an inner waterproof wall capable of moving up and down along the outer peripheral surface of the guide rod, and a first outer waterproof wall located at the outer side of the inner waterproof wall. The discharging container is easy to be manufactured and can reliably prevent water intrusion.

Abstract: Disclosed is a nonlinear optimization method for parameters of ocean ecological dynamics model, comprising the following steps: acquiring a state variable set and a parameter set to be optimized; building an ocean ecological dynamics model; acquiring a final cost function equation group; solving the ocean ecological dynamics model to obtain numerical solutions of each state variable; acquiring a Hamilton function of the cost function equation group under a constraint condition, and acquiring an adjoint equation based on the Hamilton function; adjusting the parameter set to be optimized based on the adjoint equation to obtain an optimal parameter set.

Abstract: A foam discharge container, including a container main body for accommodating a liquid composition and a foam discharge device which mixes the liquid composition with air and discharges it in a foam form. The foam discharge device has a plurality of porous bodies through which the liquid composition passes when the liquid composition is discharged, the plurality of porous bodies include a tip side porous body arranged in a vicinity of a discharge port of the foam discharge device, and the tip side porous body is composed of polyethylene terephthalate.
