In this article, based on one-dimension Heisenberg model, the unsymmetric bilayer ferromagnetic and antiferromagnetic thin films are investigated by using the interface rescaling approach under nonperiodic boundary condition.

本文以海森伯模型为基础，只考虑最近邻相互作用，在计入外磁场和非周期性边界条件下，应用界面重参数化方法，分别研究了由A、B两层组成的铁磁或反铁磁层间耦合薄膜中的自旋双链系统的界面自旋波及其存在的充分必要条件，重点讨论了体各向异性场和自旋链长度对界面自旋波存在条件的影响。

Besides some protein factors, such as transforming growth factor β1, insulin-like growth factor-1, some nonprotein factors, such as mechanical stimulation, hypoxia, dexamethasone and Vitamin C, are helpful to promote BMSCs differentiating into chondrocyte.

除了一些蛋白质因素如：转化生长因子β1、胰岛素样生长因子1有助于促使骨髓间充质干细胞向软骨细胞分化外，某些非蛋白质因素也具有此作用，如：力学刺激、低氧条件、地塞米松、维生素C等。

Pollcn morphology of 11 Heracleum species was examined under LM andSEM. It is shown that pollens of these specics are all of retangular type andequatorial constricted type, with polar views of 3-splitted round, obtuse triangle ortrianglc. Interspecific variations exhibit in pollen size and exine exolamelle.

Results:① there was significant difference in all personality traits except stableness and shrewdness among the three groups,(p 05). compared to the standardization samples, military pentathlon athletes were more outgoing, more dominant, more happy go lucky, bolder, tenser, but less suspicious, less apprehensive, and less self sufficient.② there was significant difference in the personality traits of outgoingness, happy go lucky and self sufficiency among the three grades of athletes (p 05). but the international master athletes scores of the personality traits varied little.

结果： ① 3组被试16个因子得分除稳定性和世故性外均存在显著性差异（p 05），方差主要来源于组间；军事五项运动员乐群性、恃强性、敢为性、紧张性和兴奋性较高，怀疑性、忧虑性和独立性较低（p 05）；②国际级健将，国家级健将和一般运动员仅在乐群性、兴奋性和独立性上存在显著差异（p 05），国际级运动员各因子得分变化较少，国家级和等级运动员的变化较大。

Mycorrhizal spores in most rhizospheric soil of weed species, except Vida cracca, TrfoHum npens and Oxalis cornculata, decreased significantly. 2 Influence of coexisting of various plant species on AMF colonization in Pb polluted soil Comparing with monoculture,the results showed mat diversity did not affect on die AMF colonization of weed plants planted in soil at the concentration (334.5251mg/kgsoil or nonpolluted soilsignificandy.In the experiment of species combination with Trfolium repens, Lolium perenne, Poa annua, Plan tago virginica, the infection rate of all species increased in Pb treatment except Poa annua, implying that diversified plant species coexistence may alleviate the impacts of Pb on mycorrhizal colonization.

铅污染土壤条件下不同植物物种互作对菌根的影响通过盆栽加铅模拟试验，在铅污染(334.5251mg／kg土)的土壤中，黑麦草、早熟禾、白车轴草和北美车前无论是对照还是铅处理，多植物物种共存组合中的杂草菌根侵染率与单个物种相差不大，AMF菌根侵染率的处理间差异的变化趋势在铅污染的土壤和对照土壤条件下表现一致，但铅处理与对照相比，除了早熟禾外，菌根侵染率均升高，说明杂草多样性对菌根有一定的保护作用。
