The main functions and performance parameters of the IFD Receiver for CINRAD/ CB Pulsed Doppler Weather Radar are presented.

介绍CINRAD/CB脉冲多普勒天气雷达数字中频接收机的主要功能和技术性能。

IFD Convert is a Pocket PC professional Converter which allows you to convert values between any type of units.

通用转换是一个掌上电脑专业转换您可以转换价值之间任何类型的单位。

One year survival rate of IFD group is 63%, non-IFD group is 83.9% ( p 0.05).

IFD组1年存活率为63.0%，无IFD组1年存活率为83.9%（P0.05）。

The problem of instrument failure diagnosis ( IFD) can be solved using dedicated observer scheme ( DOS).

Random Variable Approach of Determining Threshold in IFD

传感器故障诊断中确定阈值的随机变量方法

Prophylaxis or early treatment should be considered given the high mortality of IFD.

由于IFD的高死亡率，应考虑预防或早期治疗。

While the density of 82% of falx with IFH was higher than that of temporal muscle, of 18% both were similar. The density of each segment of the cerebral falx depended on the position and quantity of the blood.

纵裂池出血时82%出血处大脑镰密度>颞肌密度，18%二者相仿，大脑镰各段的密度改变视纵裂池出血部位和量而异；

Materials and Methods: To estimate visually the density of 100 cases with normal cerebral falx and 50 cases of that with IFH, and to measure CT value of each segment respectively, comparing them with the density of temporal muscle.

材料和方法：与颞肌密度对比，目测100例正常大脑镰和50例纵裂池出血的密度，并测量其各段CT值。

Subjects with FPH exhibited distinctly impaired early-phase insulin secretion as compared with IFH group and IPH group.

FPH组较IFH和IPH组有显著的早期相胰岛素分泌缺陷；

Result: Twenty_four cases were performed the repair of spleen rupture or splenectomy partly, 8 of conservative treatment, which of one failed of that was cured by the splenetic artery sponge_tent infarction with the help of DSA, and no perioperative death.

结果：24例行脾裂口修补或部分脾切除术，8例保守治疗，其中1例失败后经DSA诊断并行脾动脉栓塞治愈，无围手术期死亡。

Conclusion: Lowenergy HeNe laser irradiation has twoway effect on regulation the proliferation reaction of splenetic T lymphocyte of S180 bearing mouse.

结论：低能量氦氖激光照射对荷瘤小鼠T淋巴细胞增殖具有双向调节作用。

Objective 1.To study on hematopoietic cells, thymocytes, splenetic, testicular and liver cells apoptosis and the expression of P53 gene in irradiated mice.

目的1.研究辐射对骨髓、脾脏、胸腺、睾丸、肝脏细胞的凋亡及P53基因表达的影响。

The lymphocyte transforming rate and phagocyte phagocytosis rate of the mice were examined. The T-cell subgroup function of the splenetic lymphocytes was detected by the method of flow cytometry.
