比较是人们将各种对象或某一对象的组成部分或属性区分出来而确定其异同的逻辑方法,它是人类认识事物的最基本的思维方法。比较在科研中的意义比较研究是科学试验必不可少的条件,任何科研都不能缺少对照研究,只有对照才是比较的基础。实践证明,医学研究中的对照实验或临床疗效观察,是通过比较进行科学认识的一种重要方法。由于许多疾病是可以自然痊愈的,如感冒、气管炎、溃疡病,早期高血压、风湿性关节炎、肺结核及支气管哮喘病,往往存在着自愈或自然缓解的倾向,即使没有用特殊疗法,而只是休息、注意饮食和营养,或随着天气转暖等,也可能使一部分患者的症状减轻或消失。某药是否能加快这种痊愈过程,即是否对某病有治疗作用,只能与该病的自然过程进行比较才能确定。一种
Comparison is a logical method that distinguishes various objects or components or attributes of an object to determine their similarities and differences. It is the most basic way of thinking for humans to understand things. Comparing the significance of research in scientific research Comparative research is an indispensable condition for scientific experiments. No scientific research can lack control research. Only comparison is the basis for comparison. Practice has proved that the control experiment or clinical curative effect observation in medical research is an important method through comparative scientific understanding. Since many diseases can naturally heal, such as colds, bronchitis, ulcers, early hypertension, rheumatoid arthritis, tuberculosis and bronchial asthma, there is often a tendency for self-healing or natural remission, even without special treatment. Resting, paying attention to diet and nutrition, or warming with the weather may also relieve or eliminate the symptoms of some patients. Whether a drug can accelerate this healing process, that is whether it has a therapeutic effect on a disease, can only be determined by comparing with the natural course of the disease. One kind
