目的 探讨开腹Cool-tip冷循环单极射频消融治疗较大肝癌时射频针的排布方法,以提高较大肝癌的完全消融率.方法 2002年8月至2007年8月,64例大肝癌患者采用开腹Cool-tip冷循环单极射频消融.直径3.1～4.0 cm的肿瘤至少使用7个消融点；4.1～5.0 cm的肿瘤至少使用15个消融点；5.1～6.0 cm的肿瘤需要19个消融点；6.1～7.0 cm的肿瘤需要40个消融点,肿瘤可以被完全消融.结果 开腹射频消融治疗大肝癌完全消融率达到93.75％(60/64),并发症发生率低,近期疗效好.结论 开腹射频消融是不可切除大肝癌较好的根治性治疗手段.

Objective To study the results of laparotomy and Cool-tip radiofrequency ablation to treat large liver tumors.Methods Laparotomy and Cool-tip radiofrequency ablation were carried out on 64 patients with large hepatic cancer.To destroy the tumor completely,for tumors of 3.0～4.0 cm in diameter,7 ablations were required; for 4.0～5.0 cm in diameter 15 ablations; for 5.0～6.0 cm in diameter 19 ablations; for 6.0～7.0 cm in diameter 40 ablations.Result The complete necrosis rate of laparotomy and radiofrequency ablation was 93.75％ (60/64).The short-term results were good.Conclusions Laparotomy and Cool-tip multipoint overlapping radiofrequency ablation for large liver tumors (tumor diameter＞3 cm) could result in a high complete necrosis rate and a low complication rate.It is a good radical treatment for unresectable and large liver cancer.

基于RCP（Rapid Cooling Process）快速冷却工艺＋不同模具淬火热处理工艺，对22MnB5钢板材的淬火力学性能及微观组织进行了研究，探讨了冷速、强度硬度之间的关系，建立了三者之间的硬度指数模型。结果表明，采用加入淬火前快速冷却及改变不同模具淬火温度可以有效实现梯度冷却速率控制，冷却速率实现了从6～40℃／s的变化，微观组织从铁素体与珠光体、上、下贝氏体逐渐向“残留奥氏体＋马氏体”组织过渡，对应的强度区间范围为700～1600 MPa。建立的冷速、强度硬度模型与试验数据拟合良好。

The quenching mechanical properties and microstructure of 22MnB5 steel were investigated based on the RCP ( rapid cooling process) and with different mold quenching temperature.The relationships between the cooling rates, strength and hardness were discussed and the exponential model among them was established.The results reveal that the gradient cooling rates can be controlled effectively by adding rapid cooling before quenching or changing the mold quenching temperature.While the transition of microstructure is from ferrite and pearlite, upper bainite, lower bainite, to retained austenite and martensite from the cooling rate of 6℃/s to 40℃/s and the related tensile strength is from 700 MPa to 1600 MPa.The cooling rates, strength and hardness exponential model fits the experiment data quite well.

Effect of Ce-Mg-Si(light RE) and Y-Mg-Si(heavy RE) nodulizers on the microstructures and mechanical properties of heavy section ductile iron was investigated to develop the material of spent-nuclear-fuel containers. Two as-casts were treated by the same quality percentage of light RE and heavy RE, respectively. Four positions were chosen to stand for different solidification cooling rates of specimens. The tensile strength, elongation and impact toughness of specimens treated by heavy RE were all higher than those of the specimens treated by light RE. With the decrease of cooling rate, the mechanical properties of two specimens decreased, and the fracture morphology changed from ductile fracture to brittle fracture. The improving effect of mechanical properties between heavy RE and light RE was obvious due to the better anti-degradation property of heavy RE. While the solidification process lasted for more than 250 min, the improving effect was not obvious due to serious spheroidalizat
