鑽探不断的跃进,鑽探地質工作也必須及时进行編录。可是編录时間被計算岩心採取率占去大部分,為此,我队在計算机不够用的情況下,創制了簡易图板計算器。該計算器制作使用极簡单,不需化钱,任何人自己均能做;用处广泛,可用于乘除法及計算百分比;且計算快、节省时間。一、原理及制做过程: 我們通过若干計算过程发現岩心长度、鑽程、採取率三者有以下規律: Drilling continuous leap, drilling geological work must also be timely cataloging. However, the cataloging time was taken up to account for the majority of core take, therefore, my team in the computer is not enough, created a simple graph calculator. The calculator is extremely easy to use and does not require any money to be made by anyone; it has many uses, multiplication and division and calculation of percentages; it can be calculated quickly and saves time. First, the principle and the process of making: We found through a number of calculation of the length of the core, drill, take the following three rules:
