Objective:To explore the effects of ultrasound hyperthermia of different thermal dosage on primary liver cancer im planted in nude mices and KM mices.
目的：比较不同热剂量的超声波对肝癌鼠的治疗作用，探讨在超声波热疗中达到有效热剂量的重要性。
Conclusion thermal dosage should be regarded as a key factor during ultrasound hyperthermia, otherwise too low thermal dose might promote the growth of malignant tumour.
结论热剂量在超声波热疗中应被看作是一极其关键的因素，热剂量过小反而可促进肿瘤的生长。
The invention can monitor the thermal dosage value of a treatment object in real time and does not cause over thermal irradiation to the treatment texture and damage the normal texture.
本发明可实时监控治疗对象的热剂量值，不会给治疗组织造成过度热辐照，更不会损害正常组织。
The results showed that the impact strength(notched) of the composite was maximum and the mechanical and thermal properties were less decreased, when the dosage of modifier was 12 PHR.
当复合冲击改性剂用量为12份时，材料的冲击强度达到最大值，其它力学和热性能降低不大。
