Abstract: Disclosed are a pulp for Juncao spinning and a preparation method and use thereof. The method includes: placing a Juncao in a solution prepared from a lye, a catalyst, and an auxiliary agent and cooking to obtain a cooked solution, and then subjecting the cooked solution to pulping to obtain the pulp for Juncao spinning.

Abstract: Disclosed are a method and an apparatus for string connecting photovoltaic modules. The method includes: acquiring position information of n photovoltaic modules to be connected; categorizing the n photovoltaic modules into m partitions based on the position information of the n photovoltaic modules; generating k candidate connection solutions of an ith partition in the m partitions, wherein the ith partition includes m photovoltaic modules, and each of the k candidate connection solutions uses one photovoltaic module in the m photovoltaic modules as a starting point, and obtaining at least one string of photovoltaic modules by simulating connection of the m photovoltaic modules according to a preset connection solution; and selecting a target connection solution from the k candidate connection solutions based on an estimated cable use amount corresponding to each of the k candidate connection solutions.
