Abstract
PURPOSE: To judge simply and speedily the paper-making adequacy of wood by preparing a chart consisting of figures of double circles of various sizes of wood whose ratio of the value obtained by subtracting the internal-circle diameter from the external-circle diameter of the double circle to the internal-circle diameter is equal to the fixed value.
CONSTITUTION: A type table (chart for measuring the film-thickness ratio) consisting of double squares and double circles that typify cross sections of wood cells in the order of size and the film thickness ratio is previously prepared. The micrograph of a wood cross-section obtained by conventional methods or the image obtained by using a microscopic magnifier is compared with the chart by the naked eye to read the film thickness ratio and to judge simply and speedily the paper- making adequacy of the wood. In other words, the chart has figures of double circles which correspond to the film thickness ratio of from 0.3W8.0, so that by comparing the value of the film thickness ratio read using a microscope or the like with the chart makes it possible to know the paper-making adequacy of wood even in an inconvenient remote place.
