The interband Faraday rotation of bound electron in InSb which arises from the transition of the electrons of the valence band or the acceptor impurity level to the conduction band by using tunable CW CO and CO2 lasers has been measured. For the 10-μm wavelength range and lower carrier concentration, the experimental results show that the rotation are consisted of two parts, the sum of a positive free-carriers rotation and a negative interband rotation. For the 5-μm wavelength range of tunable CO laser,...

The interband Faraday rotation of bound electron in InSb which arises from the transition of the electrons of the valence band or the acceptor impurity level to the conduction band by using tunable CW CO and CO2 lasers has been measured. For the 10-μm wavelength range and lower carrier concentration, the experimental results show that the rotation are consisted of two parts, the sum of a positive free-carriers rotation and a negative interband rotation. For the 5-μm wavelength range of tunable CO laser, where the photon energy corresponds to the forbidden energy gap of InSb at 77 K and 20 K, resonance of interband Faraday rotation has been measured and the result is in good agreement with calculation using B. H. L theory. Oscillation in the magnetic field dependence of interband Faraday rotation has been initially observed.

本文介绍在N型InSb中用可调谐CO和CO_2激光器进行价带或受主杂质能级电子跃迁到导带所引起的束缚电子带间法拉第效应的实验研究,实验分析指出在CO_2激光器的10.6μ和9.6μ波段,对于较低的载流子浓度的样品,测量得到的法拉第旋转角是有两部分组成,是取正值的自由载流子造成的旋转角与取负值的束缚电子造成的带间法拉第旋转角之和。用CO激光器的5.3μ波段,由于光子能量接近77K和20K时InSb禁带宽度相应的能量,可以观察到带间法拉第效应的谐振现象,和BHL理论公式的计算结果相符,初步观察了带间法拉第旋转角随磁场变化的振荡曲线。

Objective: To evaluate the clinical value in measuring the free cancer cells in abdominal cavity. Methods: The abdominal cavities of 126 patients with advanced colorectal cancer were flushed with 100 ml physiological saline before the operative exploration. Then 50ml were drained from Douglas cavity for centrifugalizing. The positive free cancer cells were found in 72 patients (57.14%) and they were randomly divided into group A and group B. Group A received early intraperitoneal hyperthermia chemoperfusion...

Objective: To evaluate the clinical value in measuring the free cancer cells in abdominal cavity. Methods: The abdominal cavities of 126 patients with advanced colorectal cancer were flushed with 100 ml physiological saline before the operative exploration. Then 50ml were drained from Douglas cavity for centrifugalizing. The positive free cancer cells were found in 72 patients (57.14%) and they were randomly divided into group A and group B. Group A received early intraperitoneal hyperthermia chemoperfusion and venous chemotherapy; group B only received venous chemotherapy. Results: Nine patients had recurrence in abdominal cavities and 4 had liver metastasis in group B; two patients had recurrence in abdominal cavities and 3 had liver metastasis in group A. There was significant difference between the recurrence rates in the two groups. No serious complication was found. Conclusion: The measurement of the free cancer cells in abdominal cavity is helpful to guide the early intraperitoneal hyperthermia chemoperfusion in patients with colorectal cancer after their surgical operations, and it also has some values in judging the prognosis of colorectal cancer. \[

目的 :评价腹腔游离癌细胞测定的临床价值。方法 :12 6例进展期大肠癌患者 ,术中探查前先用 10 0ml生理盐水冲洗腹腔 ,然后从Douglas窝中取出 5 0ml生理盐水进行细胞离心检测 ,共检测出癌细胞阳性 72例 (5 7.14 % )。将其随机分成两组 ,一组接受早期腹腔温热化疗及静脉化疗 ,另一组接受静脉化疗。结果 :静脉化疗组腹腔内复发 9例 ,肝转移 4例 ;早期腹腔温热化疗组 ,腹腔内复发 2例 ,肝转移 3例 ,两组复发率有显著差异 ;两组均未见严重并发症。结论 :腹腔游离癌细胞测定有助于指导大肠癌术后早期进行腹腔温热化疗并对判断大肠癌预后有一定的价值
