In that case, the literal translation of the original paragraph is as follows: Heat transfer to a boiling liquid occurs so often that it is considered an individual operation. It is called evaporation. Heat transfer to a boiling liquid is usually regarded as a separate process. It is called evaporation. The purpose of evaporation is to concentrate a solution that consists of a nonvolatile solute and a volatile solvent. In the vast majority of cases, the solvent is water. Evaporation is carried out by vaporizing a portion of the solvent in order to produce a concentrated solution or a thick liquid. The goal of evaporation is to concentrate a solution made up of a non-volatile solute and a volatile solvent. The majority of the solvent that evaporates is water. The evaporation amount is the concentrate or thick slurry produced by the evaporation of part of the solvent. Evaporation differs from drying in that the residue is a liquid — sometimes a highly viscous one — rather than a solid. It differs from distillation in that the vapor is usually a single component; and even when the vapor is a mixture, no attempt is made to separate it into various fractions during the evaporation process ； It differs from crystallization in that emphasis is placed on concentrating a solution rather than forming and growing crystals. In uncertain situations, such as when brine is evaporated to produce common salt, the boundary between evaporation and crystallization is not clear at all. Evaporation sometimes results in a slurry of crystals within a saturated mother liquor. It differs from crystallization, which focuses on concentrating the solution rather than on the formation of crystals. In some cases, for example, in the production of table salt through saltwater evaporation, the boundary between evaporation and crystallization is not sharp. Evaporation sometimes produces a substance in the saturated mother slurry

The phenomenon of heat transfer to a boiling liquid is regarded as a separate process because it happens frequently, and this process is known as evaporation. The purpose of evaporation is to concentrate a solution that consists of a nonvolatile solute and a volatile solvent. In the vast majority of cases, the solvent is water. Evaporation involves vaporizing a portion of the solvent in order to produce a concentrated solution or a thicker liquid. The goal of evaporation is to concentrate a solution made up of a nonvolatile solute and a volatile solvent. In the vast majority of evaporation processes, the solvent is usually water. Multiple evaporations are carried out through the vaporization of part of the solvent, resulting in a concentrated solution or thick slurry. Evaporation differs from drying in that the residue is a liquid — sometimes a highly viscous one — rather than a solid. It differs from distillation in that the vapor is usually a single component, and even when the vapor is a mixture, no attempt is made in the evaporation step to separate the vapor into fractions. Unlike the drying process, the residue resulting from evaporation is a liquid (although sometimes it is a highly viscous liquid) rather than a solid. Unlike the distillation process, the vapor phase in evaporation is usually single-component; and even if the vapor phase is a mixture, no attempt is made to separate this mixed vapor phase into various fractions during the evaporation stage. It differs from crystallization in that emphasis is placed on concentrating a solution rather than forming and growing crystals. In certain situations, such as the evaporation of brine to produce common salt, the line between evaporation and crystallization is not clear-cut. Evaporation sometimes results in a slurry of crystals within a saturated mother liquor. Unlike crystallization, evaporation focuses on the concentration of the solution, rather than the formation of crystals. But in some cases, such as when producing ordinary table salt through saltwater evaporation, the boundary between evaporation and crystallization is by no means clear-cut. Evaporation can sometimes produce a crystalline slurry in the saturated mother slurry.
