The samples of 600℃ group didn't crystallize, but the color became darker and yellower as the peolongation of the heating time; the samples of 650℃ and 700℃ groups crystallized in different degrees, the translucency and Chroma decreased as the prolongation of the heating time, but the Value increased.

600℃组各样本均未晶化，随着保温时间的延长，其颜色逐渐加深，偏黄，650℃及700℃组各样本均发生不同程度的晶化，随晶化温度的升高及保温时间的延长，样本的透明度逐渐降低，亮度逐渐升高，色调变浅且饱和度逐渐降低

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

Observation under optical and transmission electron microscopes showed that the Cu-contaminated leaves were thickened, with the expansion of leaf cell and the incrassation of palisade tissues. The yellow leaves might result from the damage to chloroplasts. Cortical cell death in root system might also have a negative effect on root water absorption and transportation, causing plant water content decreased.

通过光镜和投射电镜观察，发现紫云英污染叶变厚，其原因是叶片细胞膨大和栅栏组织增厚；叶片转黄与叶绿体遭破坏有关；根系部分皮层细胞死亡可能影响根系吸水和植株水分运输，导致植株含水率降低。

At the foot of the vast jokul, a Jeep of 2020 run ver fast on the boundless and yellow great prairie, the eyeshot began to become very widen, I thought of Xu Wei's song: tasting fever, tasting loneliness, tasting gladness, love, hate, and part… In my heart, there did were some senses.

在茫茫的雪山脚下，2020狂飙于无边的泛黄的大草原上，视野开始变得开阔无比，耳边响起许巍的完美生活：体会着狂野、体会孤独、体会着欢乐，爱恨离别。。。。心里自又是一番感慨。

Thanks to new scientific measures for allotting ingredients and controlling kiln temperatures, craftsmen have not only managed to improve the quality of color glazes and find formulas for different products, but they have also successively created more than 100 glaze colors and several kinds of lusterless colored glazes.

现在采用新的科学方法进行配料和控制窑温，不仅提高了色釉的质量、找出了适合各种不同烧成条件的配方，还陆续创造了诸如红灯芯釉、宝石红、景红、锰红、铁红、火焰红、钛黄、钛花、络绿、绿郎窑、芒果、彩霞、紫罗兰等100多种颜色釉和多种无光色釉。之后又成功研制出羽毛花釉、凤凰衣釉、雨丝花釉、希土变色釉和彩虹釉等高温色釉。
