Prestorage and poststorage leukocyte filtration apheresis platelets were transfused respectively to patients with malignancy accompanied by serious thrombocytopenia after chemotherapy. Peripheral blood platelet counts were made at 1h, 24h after platelet transfusion. The effectiveness was assayed by correct count increment. The incidence rates of FNHTR were explored.

46例肿瘤化疗后血小板减少患者，分别输注保存前过滤单采血小板与保存后过滤单采血小板，输注后1h及24h后检测外周血小板计数，以校正血小板计数增殖判定输注效果，并考查FNHTR发生率。

The various trends in the POC/234Th ratio versus particle size were observed,which may be explained by a combination of 234Th decay and the preferential remineralization of POC relative to Th during particle aggregation.

本研究首先评估234Th示踪颗粒输出通量的方法，这包括不同采样方法(CTD瓶采与大体积泵采)对POC和颗粒态234Th结果的影响、POC/234Th随颗粒物粒径变化的主要原因。

In order to do research on pipe flow and pump characteristics of polymer flooding and water flooding rod-pumped well in especially high water-cut stage, rheometric test aimed at production stream from polymer flooding and water flooding rod-pumped well in especially high water-cut stage has been made, and the characteristic of production stream in especially high water-cut stage is confirmed as Newtonian fluid. Experiments using different mediums about pipe flow and pump characteristics is made. Frictional resistance and coefficient of friction resistance of annulus fluid between sucker rod and the pipe flow is calculated under different working conditions. Frictional resistance between plunger and pump barrel under different parameters is calculated based on related theory of pump characteristic and the strained analytical model of oil-well pump. Besides, using the theory of slit flow and hydraulic -clamping pressure, the frictional resistance is calculated, and the error between the result and measured value is no more than 13%.

为研究特高含水期水驱及聚驱抽油机井管流特性与泵特性，本文针对特高含水期水驱及聚驱井采出液进行了流变性试验，确定了特高含水期油井采出液的性质属牛顿流体；利用不同介质，进行管流特性与泵特性试验，得到了不同工况下杆、管环空流的摩擦阻力和摩阻系数；根据泵特性相关理论和抽油泵受力分析模型，计算了不同参数下柱塞与泵筒间的摩擦阻力，并利用缝隙流与液压卡紧力理论对柱塞与泵筒间的摩擦阻力进行了计算，计算结果与实测值误差在13%以内。
