Setting: University hospital research laboratories Subjects and Interventions: NB4 and A549 cells were separately cultured with ATRA and/or dexsamethasone for 1-3 days. NB4 or ATRA -NB4 cells were then placed in an upper insert and co-incubated with A549 cells or their conditioned medium located in a lower plate.

Three protozoa (Bodo edax, Colpoda cucullus, Amoeba proteus) were isolated from soil. The porous simulation with glass bead, soil column and root box incubation experiments were made to study the association of protozoa movement with phosphorus translocation and its influencing factors. The effects of protozoa on corn growth and corn straw mineralization were also involved. The results showed that protozoa movement in glass bead column was greatly controlled by the pore sizes. Bodo edax, about 5-7 m, could pass through the pores of 28-20 11 m in diameters. Colpoda cucullus (30-60 m) could move through the pores of 155~116 m. However, no Amoebaproteus(100~150 m) was found in the effluents from all the columns. All the three protozoa made 32P redistribution in soil column.

本研究利用土壤中常见的3种原生动物(梨波豆虫Bodo edax、僧帽肾形虫Colpoda cucullus、大变形虫Amoeba proteus)，通过玻璃珠孔隙模拟、土柱及根箱培养试验，研究3种原生动物运动与磷素运移之间的关系及其影响因素，以及原生动物对玉米磷素营养的影响，同时对3种原生动物在玉米秸秆分解中的作用做了初步的探索，研究结果表明：原生动物的运动与孔隙密切相关，Bodo edax(5～7μm)能够穿过28～20μm孔隙，Colpoda cucullus (30～60μm)只能穿过155～116μm的孔隙，而Amoeba proteus(100～150μm)不能从玻璃柱中流出。

It's pointed out that in the design of a weapon system, a collimating prism box should be installed behind the electro-optical instrument, if the condition is permitted, to control the electro-reticule generator or other functional elements added in the circuit, and make the weapon system realize the automatic collimation during flighting or driving.

指出在武器系统的设计中，如果条件允许，可在光电仪器的后方设置一个校准棱镜箱(或折反式自准凹面镜组件)，以便在控制电路中加入电十字线跟踪产生器等功能单元，使武器系统实现行进间或飞行中自动校准。

The fresh chicken feces were obtained from different age 18 healthy chicken, and were not detectedchlortetracycline. The mixture standard solution of CTC and OTC was added in fresh chicken feces at the concentration of 0.5, 1.0 and 4.0ug/ml respectively. The chicken feces were divided to two groups,one were put in the incubator under photophobic condition; another were under the natural illumination.Samples were collected after 0, 0.5, 1, 2, 3, 5, 7, 9, 12 and 15 days, The concentration of chicken feceswas determined by HPLC. According to the theory of degradation kinetics, we fitted the changed trendof concentrations in chicken feces under different time and studied the degradation characteristics ofchlortetracycline in chicken feces.
