Abstract: The present invention belongs to the field of medicine and relates to a pharmaceutical composition for preventing and treating NITM and a medical use thereof. Specifically, the pharmaceutical composition is an ophthalmic pharmaceutical composition such as an ophthalmic preparation. Specifically, the present invention relates to a pharmaceutical composition comprising 0.001% to 0.2% of atropine or a pharmaceutically acceptable salt thereof, and one or more pharmaceutically acceptable excipients; wherein the pH value of the pharmaceutical composition is of 4.0 to 6.5; the pharmaceutical composition comprises 0.5% to 5% of a pH adjusting agent, and the pH adjusting agent is any one or more selected from sodium dihydrogen phosphate, disodium hydrogen phosphate, citric acid, citrate, boric acid and borates. The pharmaceutical composition of the present invention can effectively treat and/or prevent NITM, and thus has a good application prospect.

Abstract: A method and device for determining static equivalences of distribution networks is provided. The method comprises: acquiring node admittance matrices related to a border node and a distribution network, power loss and a voltage value and a current value of the border node; constructing static equivalence determination conditions for determining static equivalences of the distribution network, comprising a consistency of sensitivity equation, a consistency of power loss equation, an equivalent network power balance equation and a Kirchhoff's current equation; and calculating static equivalent parameters according to the static equivalence determination conditions. The inventive method and device are simple and effective, where the consistency of sensitivity and power loss before and after equivalence are considered comprehensively, and where the distributed generators' voltage and power support characteristics in an active distribution network are reserved.
