Consistency degree calculation is established on the basis of known correspondence, but in real life, the correspondence is generally unknown, so how to calculate consistency of two models under unknown correspondence has become a problem. For this condition, we should analyze unknown correspondence due to the influence of different *** this paper we obtain the relations of transitions based on event relations using branching processes, and build a behavioral matrix of relations. Based on the permutation of behavioral matrix, we express different correspondences, and define a new formula to compute the maximal consistency degree of two workflow nets. Additionally, this paper utilizes an example to show these definitions, computation as well as the advantages.

本研究采用语料库对比方法,考察中外理科学者学术语篇中四词词块的结构和功能异同。研究发现,与国际学者相比,中国学者显著少用四词词块;在结构层面,中国学者过多使用动词词块,对介词和名词词块使用不足;在功能层面,中国学者显示出对文本结构词块的过度依赖,对框架、描述、立场词块等使用不足,且表达方式较为单一。中外学者在表达相同语篇功能时使用词块的结构具有差异性。研究结果对学术英语写作和教学具有借鉴意义。

目的对1例脑梗死合并房颤患者服用华法林期间INR值异常升高进行分析和干预,探讨临床药师在抗凝药物治疗中个体化药学服务的作用。方法临床药师以1例脑梗死合并房颤患者的用药为切入点,全程参与药物治疗方案的选择,实施药学监护,对患者INR值异常升高情况进行分析和干预,从药动学和药效学的角度探讨了药物相互作用对华法林抗凝作用的影响机制。结果药物和疾病状态对患者抗凝作用均有影响,头孢哌酮钠舒巴坦钠和丹红注射液是增加华法林抗凝作用的药物因素,肝功能异常则加剧了这一作用。结论脑梗死合并房颤的老年患者往往用药较为复杂,临床药师应围绕患者的抗凝方案实施个体化的药学服务,关注中西药物的相互作用,以促进药物的安全合理使用,保障患者的用药安全。
