以川西低山区天然林及其人工更新形成的1年生（Ⅰ1）、2年生（Ⅰ2）和3年生（Ⅰ3）巨桉林，坡耕地及其退耕形成的1年生（Ⅱ1）、2年生（Ⅱ2）和3年生（Ⅱ3）巨桉林为对象，研究天然林及坡耕地转变为巨桉人工林后土壤有卞几质、全氯、碱解氮、有效磷和速效钾含量变化。结果表明：各土壤养分含量均呈现出天然林〉Ⅰ1〉Ⅰ3〉Ⅰ2，坡耕地〈Ⅱ1〈Ⅱ2〈Ⅱ3，0～20cm土层高于20～40cm土层。说明天然林转变为巨桉林会造成土壤养分降低，但这种情况可能随着裁种年限的增加有所缓解；同时，坡耕地转变为巨桉林后土壤养分含量随栽种年限的增加而增加．

对复盐沉淀法分离包头稀土精矿络合浸出液中稀土与非稀土元素过程中硅的走向进行研究。结果表明,浸出液的pH和稀土浓度对进入沉淀中二氧化硅的比率影响很小,进入沉淀中二氧化硅的比率随反应温度、反应时间和硫酸钠与稀土氧化物的质量比的增大而明显增大,溶液中悬浮的氧化硅及氟硅酸钠伴随着稀土复盐沉淀过程而共同沉淀;当硫酸钠过量时,氟硅酸钠能够与硫酸钠形成复盐而沉淀。经过复盐沉淀分离稀土与非稀土元素以后,还有80%多的硅保留在溶液中,在合成冰晶石过程中会参与合成反应。

Many patients will be HSV-1 seropositive before treatment with mtHSV for tumor therapy. Balb/c mice were injected intraperitoneally with mtHSV and wtHSV. HSV seropositive and naive Balb/c mice were established sarcoma in the armpit of left forelimb and treated subsequently with mtHSV intratumorally. Tumor mean growth ratios were inhibited greatly in wtHSV seropositive mice, but there was no difference between mtHSV seropositive mice and naive mice. Compared with different doses of mtHSV on tumor therapy, the effect would be better if the dose of mtHSV was higher. The effects between single and multiple treatments with the same dose of mtHSV were not essentially different. We concluded HSV seropositivity could not weaken but enhance the effect on mtHSV-mediated tumor therapy. The cytotoxicity of PBMC from HSV seropositive and naive mice to S-180 cells in vitro showed the killing percentage mice was the highest in wtHSV seropositive. Cytokines transcription level of PBMC showed the IFN-gamma were enhanced remarkably in the early and late infected time in HSV seropositive mice, which is an important factor to inhibit the tumor growth or eliminate the tumor directly, and TNF-alpha also played important role in anti-tumoral function in wtHSV seropositive mice.

基于第一性原理方法,采用周期性平板模型,研究了N_(2)分子在掺杂体系TM-MoS_(2)(TM=Fe、Ir)表面的吸附和解离行为.研究表明:N_(2)分子在TM-MoS_(2)(TM=Fe、Ir)表面吸附能依次为0.62和0.47 eV,而完整MoS_(2)表面的吸附能只有0.08 eV,说明掺杂之后对N_(2)表现出略好的吸附性能.差分电荷密度分析表明,N_(2)吸附后,掺杂Fe、Ir原子与两个N原子之间电荷有所增加,N-N键之间的区域电荷密度减少,N-N键的强度减弱.态密度计算结果发现,N_(2)在吸附过程中,主要是N原子的2p_(y)、2p_(z)轨道与Ir的5d_(xy)和5d_(z^(2))以及Fe的3d_(xy)和3d_(z^(2))发生杂化作用.通过分析解离活化能,N_(2)在掺杂体系TM-MoS_(2)(TM=Fe、Ir)表面解离需要活化能均较高,且远大于在相应掺杂表面的吸附能,说明N_(2)在掺杂体系TM-MoS_(2)(TM=Fe、Ir)表面解离应该表现为分子吸附或脱附.
