Effects of boron and molybdenum fertilizer on plant growth and cell ultra-microscopic structure of Chamaecrista rotundifolia were studied by pot test.

通过盆栽试验探讨了红壤施用不同浓度的硼、钼微肥对圆叶决明植株生长和叶肉细胞超显微结构的影响。

The results showed that plant height, branching number, dry matter weight and uptake of B and Mo of Chamaecrista rotundifolia were increased by application of 1.0, 3.0, 7.0 mgkg^(-1) of boric acid or 0.5, 1.0, 4.0 mgkg^(-1) ammonium molybdate, the stabilities of cell wall, cell membrane and chloroplast membrane structure enhanced, the number of chloroplast increased, and the best effects were observed by the application of 3.0 mgkg^(-1) boric acid or 4.0 mgkg^(-1) ammonium molybdate.

结果表明，施用1.0、3.0、7.0mgkg^(-1)的硼酸或0.5、1.0、4.0mgkg^(-1)的钼酸铵都能增加圆叶决明的株高、分枝数、干物质重和硼／钼元素的吸收，稳定细胞壁、细胞膜、叶绿体膜的结构，增加叶绿体的数量；其中以3.0mgkg^(-1)的硼酸或4.0mgkg^(-1)的钼酸铵为最佳施用量。

We have deposited the undoped and boron doped silicon thin films in the p champer using radio frequency plasma enhanced chemical vapor deposition method.

采用传统射频等离子体增强化学气相沉积技术，沉积了未掺杂和硼烷掺杂浓度为0.4％的两个系列的硅薄膜。

In joins in the cobaltous acetate resultant besides nano-carbonball, has tubular of matter the minority head harness metal. Adds response the formic acid nickel to be possible to obtain the particle size comparatively greatly to have the carbon-encapsulated. The Co3B obtained resultant shape not to be more irregular also to have the carbon-encapsulated.

当加入醋酸钴反应时，产物中除奈米碳球外，还具有少数头戴金属钴之管状物质；而加甲酸镍时，则可得到较大粒径具有包覆现象之奈米碳球；然而加入硼化钴所得反应产物形状较不规则且具有包覆之奈米颗粒。

The microstructure and mechanical properties of the testing steels have also been studied contrastively.

实验室试制了低碳Nb、V微合金化含硼冷镦钢，并对试验钢的组织和性能进行了对比研究。

Solid medium was using to study the effect of sugar, boron, calcium on pollen germination and pollen tube growth of Corylus heterophylla Farnch.× C. avellana L..

The squaric acid, croconate acid, salicylic acid which contain hydroxy can form a big integration anion with Boron, assemble many lithium salts combining with the lithium ion which should have novel structure and a good electrochemical property.

方酸、克酮酸、水杨酸由于含有羟基，能与B形成大螯合阴离子，从而与锂离子可以组装成许多具有新颖结构和良好电化学性质的锂硼盐电解质。

The basic reason for oxygen concentration reduction in heavily Sb-doped CZSi was that oxygen solubility decreased when element Sb with larger radius doped degenerately into silicon crystal.

为解释重掺锑硅单晶中氧含量较普通直拉硅低，且随着掺锑量增加，氧含量下降，而重掺硼硅单晶中氧含量并不降低这一实验事实，应用热力学计算，得到重掺锑硅单晶生长时，生成Sb〓O〓的反应不能自发进行，因此不会因Sb〓O〓的大量挥发而使重掺锑硅单晶中氧含量降低。

The result shows it is viable that 45 steel ooze boron oil quenching replacing conventional 45 steel found produces tower wheel in water tank drawbench.
