Application of computer in quantitative analysis chemistry experiment

Abstract

The invention discloses an application of a computer in a quantitative analysis chemistry experiment. According to experiment schemes of 19 experiment items of the quantitative analysis chemistry experiment, a mathematic model is written, according to the mathematic model, the computer language is used for carrying out programming on the mathematic model; a compiled computer program can automatically process experiment data, absolute errors, relative errors and the like are computed automatically; the computer can automatically evaluate the experiment performance of students according to the computing results of the experiment data and relevant relative errors; the computer automatically signs the correcting date; the computer automatically prints lab report books of the students; the computer automatically stores the experiment performance of the students and the lab report books of the students; timely calling can be achieved, so that calling during teaching quality evaluation and teaching quality inspection in the future is convenient. According to the application, the experiment content is wide in selecting face, representativeness is strong, practicability is strong, pertinence is strong, and systematicness and operability are strong.

Description

technical field [0001] The invention belongs to the field of computer applications, in particular to an application of a computer in quantitative analysis chemical experiments. Background technique [0002] Chemical experiments are indispensable for colleges and enterprises laboratories, and a large number of quantitative analysis and data calculations are required in quantitative analysis chemical experiments. In traditional quantitative analytical chemistry experiments, people use paper, pens, calculators, etc. to record and calculate data. [0003] The traditional manual calculation method is prone to inaccurate calculation results of students changing data and experimental data, resulting in large calculation errors, easy loss of experimental reports and experimental data, and the accuracy and precision of students' experimental results cannot be monitored at any time. It consumes a lot of calculation time, and at the same time, teachers need to consume a lot of time to...

[0003] The traditional manual calculation method is prone to inaccurate calculation results of students changing data and experimental data, resulting in large calculation errors, easy loss of experimental reports and experimental data, and the accuracy and precision of students' experimental results cannot be monitored at any time. It consumes a lot of calculation time, and at the same time, teachers need to consume a lot of time to evaluate students' grades, which improves the efficiency of students writing experiment reports and the efficiency of teachers correcting experiment reports
