Methods Genetic information about Chinese Han X-ray worker obtained through questionnaire. Polymerase chain reaction and restriction fragment length polymorphism analysis were used to identify genotypes of every subject. Data analysis used SAS 6.12 statistical software.

方法问卷调查X射线工作者高血压病家族史，采用聚合酶链反应、限制性内切酶片断长度多态性的方法检测X射线工作者ACE和M235T基因多态性，SAS612软件进行资料分析。

The time of statistical experiments c has a kind of influence on prediction results, and the prediction accuracy approached stable when c ≥ 200. ( 3) The prediction accuracy of various Markov chain prediction methods had a suitability to difference distributions.

统计试验的次数c对预测结果有一定的影响，当c≥200时，预测精度趋向稳定。（3）各种马尔可夫链预测方法的预测精度具有对不同分布的适应性。
