The influences of Ce on the microstructure and mechanics performances of Ti-Fe-Mo-Mn-Nb-Zr alloys were studied and presented in this paper. The microstructure of no-Ce Ti-Fe-Mo-Mn-Nb-Zr alloy was thick, long and dendritic,and the microstructure of alloy was fined by Ce. With the increase in Ce wt%, the microstructure became equiaxial gradually.

研究了稀土 Ce对 Ti- Fe- Mo- Mn- Nb- Zr合金组织与力学性能影响，结果表明：不含 Ce的为粗大的长枝晶组织，加入 Ce后组织有所细化，并随 Ce量增加而逐渐等轴化，直至形成等轴晶；硬度方面随 Ce的加入有所降低；在 Ce含量较少时随 Ce的增加压缩强度也增加，但当 Ce含量增大一定量时，Ce增加降低了压缩强度。

When the Al-Mg-Zr-Sc welding wire was used as filling material,the grains of welding seam were refined obviously,and the weld joint was greatly strengthened by forming of fine equiaxial grains layer in fusion zone .

但采用Al-Mg-Zr-Sc合金焊丝为填充材料时，焊缝晶粒组织明显细化，熔合区形成的细小等轴晶层提高了基材与焊缝填充材料的结合力，焊接接头的屈服强度比采用Al-Mg-Zr合金焊丝为填充材料时提高了100 MPa，显著提高了Al-Mg-Sc合金焊接构件的许用强度，因此焊接Al-Mg-Sc板材更宜采用Al-Mg-Sc-Zr焊丝。

The relationship between weed invasion and intensity was analysed on sown pasture mixed by whiteclover and perennial ryegrass,and the preliminary results were that 1the number of invasive weeds ismainly dependent on grazing intensity;2the trend of species diversity was successively increase-decrease-increase when the grazing intensity is increase;3 principal invasion weed species are Lysimachiahemsleyana, Eragrostis nigra, etc,8 species;4the sown pasture in question is pioneer stage of the recoverysucce...

本文分析了白三叶草十多年生黑麦草混播人工草地上杂草入侵与放牧强度之间的关系，得出如下初步结论：1）杂草入侵的种数主要决定于放牧强度；2）α物种多样性随放牧加重而有增－减－增的趋势；3）入侵的主要杂草种为点腺过路黄等8个种；4）所论人工草地都处在恢复演替的先锋阶段，因而草地退化的进程还是能予以遏制的。
