Investigation was made of the sputtering rate in glow discharge lamp with re-lation to constituent of 25 different specimens of 6 binary systems, namely, Cr-Fe, Bi-Sb,Cu-Zn, Ag-Cu, Al-Zn and Cd-Sn, by measuring mass loss after each sputtering under con-stant Ar pressure and voltage applied. The correlation, in general, between sputtering rate andconcentration of constituent of these non-intermetallic binary alloys obeys the hyperbolic lawunder steady state, yet may be approximately regarded as linear only on certain special condi-tion if the two components of the alloys with similar sputtering rates.

A new cermet sinter with through micro-porous structure was developed by vacuum liquid phase sintering method, in which Al2O3-Ni-Cr-Mo-Si-Fe powder was used as the basic material, TiH2 and CaCO3 were used as the composite pore-forming materials and hominess grains was used as dispersal particles. The cermet sinter was then infiltrated with Ag-Cu-Pb-Sn at vacuum and formed a new high temperature self-lubricating material.

以TiH2和CaCO3为复合造孔剂，以硬质微细颗粒为惰性弥散质点，采用真空烧结法制备出具有贯通型微孔结构的Al2O3-Ni-Cr-Mo-Si-Fe系金属陶瓷烧结体，并在烧结体中浸渍Ag-Cu-Pb-Sn系浸渍型固体润滑剂制备出新型高温扩散自润滑材料。

In this thesis, the present situation of heavy metals pollution and the physical and chemical properties of soils and the enrichment situation of heavy metals (Cd、 Hg、 Pb and Cr) in the vegetable body in the Harbin city greenbelt was investigated and evaluated. The results were showed as follows:The four heavy metals all polluted greenbelt soil by different degree in Harbin. The pollution of hydrargyrum is the most serious and reaches to the heavy pollution. The next pollution is plumbum, cadmium and chrome.

本文针对哈尔滨市区城市绿地重金属污染状况、土壤的理化性质，以及重金属(Cd、Hg、Pb和Cr)在植物叶片的富集情况进行了分析，并且对哈尔滨市区重金属污染状况进行了综合评价，结果表明：(1)哈尔滨市绿地土壤表层这四种重金属都有不同程度的污染，其中以汞的污染最为严重，达到了重污染；其次是铅和镉，铬的污染较小。

结果表明：Cr胁迫0~800mgL^(-1对白骨壤成熟胚轴的初期萌发无明显的影响。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。
