Results: Of all the semen samples, 8 were HCMV positive, 4 HSV-Ⅱ positive, but none were both HCMV and HSV-Ⅱ positive. HCMV late antigens were positively and HCMV early antigens negatively expressed in the spermatogenic cells of the 8 HCMV positive cases. In the 4 HSV-Ⅱ positive cases, 3 were positively and 1 weakly positively expressed. In the semen of the 12 positive cases were found large numbers of immature spermatogenic cells, with different manifestations of apoptosis, such as chromatin pycnosis, vacuoles, damaged nuclear membrane, and apoptotic bodies, but without virus infection-induced specific morphological alteration.

结果：83例精液样本PCR检测HCMV阳性8例，HSV-Ⅱ阳性4例，未发现2种病毒同时阳性病例。8例HCMV阳性病例ICC标记生精细胞HCMV晚期抗原均见阳性表达，HCMV早期抗原均为阴性表达；4例HSV-Ⅱ阳性病例ICC标记生精细胞3例阳性表达，1例弱阳性。12例病毒阳性病例均发现较多未成熟生精细胞，并有不同程度的核染色质固缩、出现空泡、核膜破损、核崩解、凋亡小体等凋亡现象，但未能找到病毒感染的特异性形态学改变。

Empirical results indicate that all three hypotheses of this study sustained: Hypothesis 1—"career development" and "training" in the enterprise repatriation program has positive influence on the affective organizational commitment of repatriates;"career development" has positive influence on the normative organizational commitment;"career development","training" and "compensation and benefit" has positive influence on continuance organizational commitment; Hypothesis 2—"conscientiousness" and "neuroticism" has positive influence on the affective organizational commitment;"conscientiousness" and has positive influence on the normative organizational commitment;"neuroticism" has positive influence on the continuance organizational commitment; and Hypothesis 3—"openness to experience" and "emotional stability" can enhance affective organizational commitment when "career development" is implemented by the organization;"openness to experience" can enhance affective organizational commitment when "training" is implemented by the organization;"conscientiousness" can reduce continuance organizational commitment when "career development" is implemented by the organization;"emotional stability" can reduce continuance organizational commitment when "compensation and benefit" is implemented by the organization; and "extraversion" can reduce continuance organizational commitment when "job arrangement" is implemented by the organization.

实证结果显示，本研究三大假设皆达部份成立，第一假设：企业施行回任措施中的「前程规划」与「教育训练」将可提升回任人员情感性组织承诺、施行「前程规划」将可提升规范性组织承诺、施行「前程规划」、「教育训练」与「薪酬管理」将会提升持续性组织承诺。第二假设：回任人员「严谨性」与「情绪稳定性」特质可提升回任人员情感性组织承诺、「严谨性」特质可提升规范性组织承诺、「情绪敏感性」特质将会提升持续性组织承诺。第三假设：「严谨性」与「情绪稳定性」特质对组织施行「前程规划」可提升情感性组织承诺、「开放的学习性」对「教育训练」施行可提升情感性组织承诺、「严谨性」对「前程规划」施行可降低持续性组织承诺、「情绪稳定性」对「薪酬管理」施行可降低持续性组织承诺、「外向性」对「工作安排」施行可降低持续性组织承诺。兹就上述结果提供对企业与后续研究者的建议。对企业的建议为：1。企业在回任措施中应加强前程规划的设计：企业除了就短期的薪酬与工作安排条件让回任员工愿意留任，亦应思考如要让回任员工能够投入工作中，长期的规划与发展不可缺少。2。外派人员人格特质甄选工具的运用：为了能找到具备严谨性、情绪稳定性与开放的学习性特质的人选，甄选用的工具即扮演著十分重要的角色，可利用人格特质测验、面谈等甄选工具。
