还生口服液抗癌作用机制的研究

报道了还生口服液对荷瘤小鼠（Ｓ１８０、ＥＡＣ、Ｌ６１５）癌细胞膜、红细胞膜Ｎａ＋，Ｋ＋－ＡＴＰａｓｅ活性的影响和对荷瘤小鼠红细胞膜免疫功能的影响。结果表明，还生口服液可显著抑制癌细胞膜、荷瘤小鼠红细胞膜Ｎａ＋，Ｋ＋－ＡＴＰａｓｅ的活性，同时可显著提高荷瘤小鼠红细胞膜的免疫功能，可使红细胞免疫复合物花环率（ＲＦＩＲ）降低，而使红细胞Ｃ３ｂ受体花环率（ＲＢＣ—Ｃ３ｂＲＲ）、红细胞Ｃ３ｂ受体花环促进率（ＲＦＥＲ）显著提高。本文结果揭示，还生口服液抗癌作用机制有部分是通过抑制癌细胞膜，荷瘤机体红细胞膜Ｎａ＋，Ｋ＋－ＡＴＰａｓｅ的活性，提高荷瘤机体红细胞免疫功能完成的。

电腐蚀法制备n-Bi_2 S_3光电极

电腐蚀法是以金属腐蚀原理为基础的。它是一种极为简便的制备光电报的方法。对于n—Bi_2S_3光电极的制备,只要将镀有铋的金属或导电膜放在电腐蚀液(硫化物电解质溶液)中,加上一定的电压,便可在金属基板或导电膜上形成一层具有光电性的硫化物沉积物,此即n—Bi_2S_3,且有半导体性能,其禁带宽度为1.22ev。它在一定的电解液中具有较好的稳定性,我们对n—Bi_2S_3电极进行了初步的研究,发现在光的长期照射下,光电性基本不变。     

Simultaneous Multithreading Fau Tolerance Processor

Transient fault detection mechanism is added to simultaneous muhithreading architecture. By exploiting both ILP (Instruction l~evel Parallelism) and TLP (Thread Level Parallelism), Simultaneous Multithreading(SMT) Fault Tolerance Processor can be expected to achieve better tradeoff between performance and hardware cost than traditional Fault Tolerance Processors. Detailed simulations of 3 of SPEC95 benchmarks show that executing two redundant programs on the fault-tolerant microarchitecture takes only 40%-61% longer than running a single version of the program. The new instruction fetch algorithm enhances the performance by 0. 4%～1% to most of the benchmarks we choose randomly.

将环境质量评价学、GIS(地理信息系统)和编程技术相结合，拟定了无公害农产品产地空气和灌溉水环境条件预警区划分的技术路线。基于GIS建立了自贡市部分地区预警区图层数据库，并通过嵌套编程对废气和废水浓度衰减预测和综合指数计算，矢量化地形图的缓冲分析圈定预警区范围，GIS区域求并，生成预警区成图。不满足产地空气和灌溉水环境条件的预警范围分别为75．93km^2和89.85km^2，综合影响范围129．99km^2。     

The terrestrial NPP simulations in China since Last Glacial Maximum

Based on Atmosphere-Vegetation Interaction Model （AVIM）, the magnitude and spatial distribution of terrestrial net primary productivity （NPP） in China is simulated during three different geological eras, Last Glacial Maximum （LGM）, Mid-Holocene （MH） and the present. The simulation shows that the glacial-interglacial variation of East Asian summer monsoon in China is the key factor affectfng the NPP change. During the three eras, mean NPPs are 208 g/m^2·a, 409 g/m^2·a, and 355 g/m^2·a. The total NPPs are 2.05 Pg/a, 3.89 Pg/a and 3.33 Pg/a, respectively. The terrestrial NPP in China during warm-humid climate is larger than that during cold-arid eras, and the correlation analysis between NPP and climate factors suggests that temperature is the primary factor affecting the terrestrial NPP during 21 kaBP （LGM）, and for 6 kaBP （MH） and the present the primary factor is precipitation.     

Application of microfluidic chip to realize controllable pH gradient

A kind of PH gradient microfluidic chips through soft-lithography microfabrication for isoelectric focusing (IEF) and high performance liquid chromatography (HPLC) is introduced here. These pH gradient chips have the advantages such as easy fabrication, controllable pH range and precision, isoelectric focusing and separation at the same time, low voltage for isoelectric focusing, and time stable pH gradient. This method has potential application to sample preparation, separation and analysis of microfluidic chips.     

Simulation of a compartment fire using a zone model

This paper presents the zone modeling analysis of a single compartment flashover fire. Two criteria are applied in the model to judge the onset of ignition for different combustibles. By calculating the total received energy through radiation or the surface temperature of the combustible, the fire growth can be quantitatively determined. The improved zone fire model shows the influence of different combustibles upon the fire growth. This model is better than the traditional zone model because the common criteria of flashover, i.e. an upper layer temperature of 600℃ and the heat radiation intensity received by the floor of 20 kW/m^2, have not been applied in it.
