中文摘要：

通过研究血液成分来判断急性颅脑损伤的严重程度。选用血液中的红细胞、中性粒细胞、红细胞计数等16项指标作为研究对象，用因子分析法对其进行分析，提取与急性颅脑损伤有关的6种因子指标；用判别分析法检验6种因子指标判别脑损伤严重程度的准确性，其准确率可达85％。研究表明，因子分析法能够准确的分析出血液中与急性脑损伤严重程度有关的指标，期望成为研究脑损伤的有效方法。

英文摘要：

The aim of this research on blood components is to judge severity of the acute craniocerebral injury. A total of 16 indicators are used including red blood cells, neutrophils and red blood cell counts. Using the factor analysis method and the 16 indicators for analysis can obtain six kinds of characteristic factor index related to severity of acute brain trauma. A discriminant analysis is done to judge accuracy of the severity of acute craniocerebral injury by examining the six factors. The accuracy rate can reach 85 %. The results show that the factor analysis can accurately analyze blood components Of acute brain injury related indicators, which is expected to be an effective means in the research of craniocerebral injury.
