The results showed that the TiN andN films are polycrystalline phase. The properties and structure of TiN films are mainly determined by the N2 mass flow rate, and as the N2 mass flow rate increases, the structure of the TiN films transforms to f.c.c. type leading to better the properties of films. The presence of negative bias voltage can optimize the grain of TiN films, lower the defect proportion and denser the films, which improves the hardness of films. The TiN films conform to the free carrier absorption mechanism and there are many of free electrons with lower N content in TiN films. With the increase of N content, the quantity of free electrons and reflectivity of films decrease, and the plasma frequence shifts to the lower energy, which leads to the regular change of colors of films from silver, yellowy, golden to yellow-red, meanwhile the lightness of films decreases. The goldenN film consists of TiN and ZrN phase, but belongs to a sigle f.c.c. structure with (111) preferred orientation. The Zr-doping dosen't change the position of the valance band, conduction band and forbidden band ofN film, but leads to the presence of new energy levels, which is the reason thatN film remains golden. The transparent hard films with good corrosion resistance and high hardness have been prepared and the further reseachs showed that the grain size of those films is by far smaller than the wave length and the width of forbidden band of those films is very broad, is the reasons that those films are transparent.
研究表明:氮化钛和N 薄膜为多晶态,氮流量决定了氮化钛薄膜的结构和性能,增加氮流量能使氮化钛薄膜的结构向面心立方结构转变,从而得到性能良好的氮化钛薄膜;施加负偏压能优化氮化钛晶粒和减少薄膜中的缺陷,使膜层变得更致密,从而提高薄膜硬度;氮化钛主要遵循自由载流子光吸收,氮含量较少时薄膜中的自由电子数目较多,随着氮含量的增加,薄膜中的自由电子数目不断减少,反射率逐渐降低,等离子体频率向低能端移动,从而使薄膜颜色出现规律变化,由金属色银白色到淡黄、金黄再到红黄,并且薄膜亮度呈下降趋势;金黄色的N 薄膜中存在TiN 和ZrN 的分离相,但其为单一的面心立方结构并具有(111)面择优取向;相对于TiN 薄膜,Zr 掺杂后,并没有使薄膜的导带、价带和禁带发生变化,只是在TiN 禁带内增加了新能级,这也正是掺杂Zr 后,薄膜仍

In the meantime, at Geneva, Calvin was cleverly seeking to bring about a compromise between the extremes of the Lutheran literal and the Zwinglian figurative interpretations, by suggesting instead of the substantial presence in one case or the merely symbolical in the other, a certain mean, ie "dynamic", presence, which consists essentially in this, that at the moment of reception, the efficacy of Christ's Body and Blood is communicated from heaven to the souls of the predestined and spiritually nourishes them.
在此同时,在日内瓦,卡尔文被巧妙地寻求实现一个折衷两个极端之间路德直译和zwinglian形象化表述,暗示而不是大量存在,在一个案例中,或仅仅是象征意义,在另一方面,在一定意味着,即"动态",在场的,其中主要是在这方面,目前的接待,效能的基督身体和血液,是沟通从天上到心灵的命中注定和精神滋养。

CFC syndrome and CS can be distinguished from NS by the presence of ectodermal abnormalities, mental retardation and a lack of familial cases. CFC syndrome can be distinguished from CS by the rare presence of papillomata, fetal pads, acanthosis nigricans, wrinkled palms and soles, and loose skin of the hands and feet.

1A series ofω-alkylmercapo acid were synthesized by two methods:one involved the reaction of the appropriateω-bromoalkyl acid with mercaptide under the presence of base;the other method was used only for the long alkyl compound by the reaction ofω-alkenyl acid and alkanethiol in the presence of AIBN.

Moreover,the selective oxidation of primary and secondary alcohols to corresponding carbonyl compounds with the multinuclear copper complexes Cul-Cu4 as catalysts have been conducted using TBHP and O_2/TEMPO,respectively.Among them,the copper complex Cu3 showed the best performance.On the performances of the two classes of oxidants,benzylic and heterocyclic alcohols could be effectively oxidized to carbonyl compounds.Specifically,the secondary alcohols could be effectively oxidized to ketones with excellent selectivity up to 100%in the presence of TBHP and the allylic alcohols could be effectively oxidized to aldehydes in the presence of O_2/TEMPO system.

Sn with the content of 0.004% in the lithosphere is almost in presence of cassiterite and little in presence of Sn-contained sulfide. Since 1980s, the anticancer active study on organic complex compounds has attracted considerable attentions, it becomes another hot issue after the study on Pt. When time up to the year 1989, the anticancer active measurement of more than 2000 kinds of Sn-contained complex compounds have been carried out by Cancer Academy, U.S, with the results showing half of these Sn-contained complex compounds posses antileucocythemia(P388) activity. Thereafter, Sn-contained complex compounds synthesized by hydrothermal reaction also become a hot issue people focus on.
Sn在地壳中的含量为0.004%,几乎都以锡石的形式存在,此外还有极少量的Sn的硫化物。20世纪80年代以来,人们对Sn有机配合物抗癌活性的研究产生了浓厚兴趣,成为继顺铂之后又一活跃的研究热点,到1989年,美国国家癌症研究所对2000多种Sn的配合物进行了抗癌活性测定,结果表明,50%的配合物具有抗P388白血病活性,故水热溶剂热合成锡的配合物也成为人们的研究热点。

Aiming at the currently shortage of XML streams quality detecting, this paper proposes a new forecasting method of XML streams quality by least squares support vector machines, which is used the method of XML keys' vector matrix as windows, and vector product wavelet transform to multilevel decompose and refactor the XML streams series, that can fulfill real-time checking demand of XML quality, and ensure constraint, consist- ency and integrality. For even more adapting net load, it proposes a control strategy by weight and adaptive adjustment to ensure XML streams quality.
