遗落的明珠——浅谈岑参山水写景诗的艺术价值

唐代诗人岑参以边塞诗闻名于中国古代诗坛，同时他的山水写景诗写得也毫不逊色，取得了极高的艺术成就，特别是其清淡、清新、清旷、清丽的“四清”并行的艺术风格尤为突出。由于历史和个人原因，岑参的山水写景诗历来鲜为人知，但这并不能否定其特有的艺术价值。     

互联网市场:理性的高速发展——直击“2007中国互联网市场年会”

<正>2006岁末,美国《时代》周刊年度风云人物的揭晓让人意外之余又都颇感认同——全球逾10亿“互联网使用者”共同获此殊荣。的确,历经十几年的发展,“互联网”已密切融入人们的生活。与此同时,互联网市场也发展成为今天涵盖基础接人服务、电子商务、网络游戏、即时通讯、网络搜索等诸多领域的庞大产业。那么目前我国互联网产业整体发展状况以及未来的发展趋势究竟如何呢?透过1月19日于北京成功举办的“2007中国互联网市场年会”,我们可以对此有一个比较深入的了解。

新型重整催化剂的研究——Pt／L中沸石酸碱性的作用

Ｐｔ／ＫＬ、Ｐｔ／ＢａＫＬ及Ｐｔ／ＨＬ上的铂与沸石的酸碱位发生相互作用，导致催化剂上存在不同电子状态和粒度分布的铂位，从而产生有着完全不同催化作用、不同抗硫性能的两类催化剂，即以碱性沸石为载体的“单功能”催化剂和以酸性沸石为载体的“双功能”催化剂。在Ｐｔ／ＫＬ、Ｐｔ／ＢａＫＬ催化剂上，存在着对硫敏感的具有环化脱氢功能和对硫不敏感的仅具有脱氢功能的两类铂活性位。     

内燃机油添加剂之间相互作用的研究

探讨了内燃机油添加剂之间的相互作用，磺酸盐与水杨酸盐的相容性差，混合后有沉淀物生产；水杨酸盐与丁二酰亚胺，ＺＤＤＰ有较弱的相互作用，添加量小时无沉淀物生成，添加量大时才有沉淀物生成；磺酸盐与丁二酰亚胺，ＺＤＤＰ的相容性好，混合后沉淀物生成。该结论为内燃机油的调配，贮存和全用提供了科学依据。     

Zr-2/Cr反应扩散研究

研究了Zr-2/Cr扩散偶在1023－1123K范围内的反应扩散，用扫描电镜观察反应宽度，用能谱仪（EDS）测定了反应层Zr,Fe和Cr沿扩散方向的浓度分布，研究了反应层的生长动力学，结果表明，反应层生长基本符合抛物经规律，生长过程受扩散控制，用Boltzman-Matano-Heumann模型计算了Cr在反应层Zr（Fe,Cr）2中的互扩散系数D，得到了互扩散系数D与温度的Arrhenius方程，由计算的扩散数据与Cr在Zr中形成稀固溶体时Cr的扩散数据比较可知，Cr在金属间化合物Zr（Fe,Cr）2中的扩散比在稀因溶体中的扩散快5个数量级。     

OSCILLATION AMPLITUDE OF THE FREE END OF A FLEXIBLY MOUNTED RIGID CYLINDER IN TRIANGLE ARRANGEMENT

In this paper,the oscillation amplitude of the free end of a group of threecylinders are studied.The three cylinders are erected at the vertices of an equilateral trian-gle,and three arrangements are made in this study.One of the three cylinders is served asa working cylinder which is mounted by a flexible cantilever and two accelerometers areattached on the free end in two directions.The results of the three-cylinder arrangementare compared with those of two cylinders in tandem/side-by-side arrangement in the samecondition.The experimental results show that the rear cylinder of a group of three cylin-ders is affected more seriously than that of the corresponding two cylinders in the contrastarrangement.The main direction of oscillation is changed.The transversal oscillation isstronger than the longitudinal oscillation in the three-cylinder arrangement.On the con-trary,the transversal oscillation is much weaker than the longitudinal oscillation in two-cylinder arrangement.The largest transversal oscillat

非线性系统鲁棒吸引的动态补偿方法

考虑非线性不确定系统的鲁棒吸引问题,借助于动态输出反馈,构造了两类控制律。这两类控制律分别可使相应的闭环系统被一任意小的区域鲁棒吸引,或被一预先设置的区域有限吸引。     

Clinical study on effect of bushen shengxue paste in treating renal anemia patients

OBJECTIVE: To evaluate the therapeutical mechanism of Bushen Shengxue Paste (BSSXP) on anemia. METHODS: Chronic renal failure induced anemia patients were treated with BSSXP, clinical manifestation, anemia and renal function as indicators were observed in patients. The erythropoietin (EPO) and inhibition of colony-forming unit-erythrocyte (CFU-E) in patients' serum were determined by CFU-E in vitro. RESULTS: The patients' symptoms, renal function and anemia were improved after administration with BSSXP 1-2 course. EPO in serum was slightly increased. The inhibition of CFU-E in patient's serum was significantly decreased. CONCLUSIONS: BSSXP could improve the anemia degree, its mechanism might be through clearing the inhibitor of CFU-E in serum.
