In this bath, maleic acid was an inhibitor, when its concentration was kept at 20 mg/L, the deposition rate could reduce to 6.17μm/h, the content of nickel decreased to 1.74% and the resistivity was 7.51μΩ·cm; Potassium ferrocyanide inhibited deposition of copper, when its content was 0.5 ppm, the deposition rate decrease to 3.38μm/h, the content of nickel was 2.03%, the resistivity can reduced to 5.41μΩ·cm, the copper deposits also had higher (111) plane orientation. Thiourea was also an inhibitor in this system, when its concentration was kept at 0.8 ppm, the deposition rate was 4.72μm/h, the content of nickel in the film was 1.20%, the resistivity can reduced to 5.46μΩ·cm, at the same time, the deposition at (111) plane orientation become more favorable.
结果表明,马来酸在该体系中是抑制剂,当其浓度为20 mg/L时,镀速降为6.17μm/h,镀层镍含量降为1.74%,表面电阻率降为7.51μΩ·cm,铜层颗粒细小均匀,更有利于在(111)面上的结晶;亚铁氰化钾的加进可以明显降低镀,当其浓度为0.5 ppm时,镀速为3.38μm/h,镀层镍含量降为2.03%,表面电阻率降为5.41μΩ·cm,铜层颗粒细小均匀,(111)晶面衍射峰增强;硫脲在体系中也显示为抑制剂,当其浓度为0.8 ppm时,镀速降到4.72μm/h,镀层镍含量为1.20%,表面电阻率降为5.46μΩ·cm,形成的铜颗粒很小,同时(111)晶面衍射峰增强,有利于铜在(111)面上结晶。

The results were as follows:1 The explants with two phyllomes(about 0.2-0.5mm in size )were found to be suitable for virus-free seedling culture , which were cultured on solid MS medium supplement with 6-BA,NAA and IAA ,The result indicated that the plantlet was over 30% after three months.
主要结果如下: 1。取带2个叶原基(长度约为0.2-0.5mm)的茎尖为外植体,在附加6-BA、IAA和NAA的MS培养基上进行3个月的培养,成苗率达30%以上。另外,在切取茎尖前对薯苗热疗(37℃)4周,在基本不影响成苗率的同时,可大幅度提高脱毒率。

Can improve the survival ratio of seeding. Culturing in hormone media can make meristem tip survive once time, and the result is better than two-time-cultivation.3、The meristem tip with two phyllomes(0.3-0.4mm in size)were found to suitable for virus-free seeding culture that were cut from aseptic seeding, which led to higher survival and virus-free ratio, up to 72.1%and 54.2%.
在培养基中添加椰汁、香蕉汁等有机添加物可以明显提高成苗率。3、采用二次剥离茎尖的方法,从无菌试管苗上切取带2个叶原基(大小0.3-0.4mm)茎尖分生组织培养,成苗率为72.1%,脱毒率为54.2%。

The is related to the frequency dependent absorption cross section and the density and spatial distribution of atoms in the lower level of the transition. Position dependent 5P3/2 state densities had been combined with the collisional broadening rate 5P3/2 5S1/2 line due to both helium and cesium perturbers to yield the .The effective radiative rates of the Rb D2 line as a function of the He pressure PHe were obtained . The fluorescence intensity I780 of the 5P3/2 5S1/2 emission was measured simultaneously.
由于辐射陷获存在,有效辐射率是自然辐射率与透射因子(发射的光子在探测区域内没有被吸收的平均概率,它与吸收截面及激发态原子密度和空间分布有关)的乘积。5P3/2原子密度及其空间分布结合5P3/2 5S1/2跃迁线的碰撞增宽计算了透射因子,从而得到了不同He气压下,Rb D2线的有效辐射率。
