The growth of plantlets with the height of 1-2 cm and 3-4 leaves was compared on MS basal medium containing various organic compounds, including banana, carrot, potato, coconut water, and tryptone. The result showed that the growth of oncidium plantlets was the best on medium containing banana, potato and tryptone altogether with respect to their plant height, leave number, root number, root length, fresh weight, and dry weight. The next better media were the control and the Banana medium, followed by the Potato medium.
另外取高约1-2公分,带3-4片叶片的分化小苗,培养於含不同浓度有机添加物(香蕉、胡萝卜、马铃薯、椰子水、及tryptone)的半量MS培养基,以探讨最适合文心兰瓶苗生长的培养基,试验结果显示,在同时含香蕉、马铃薯及tryptone三种成份的培养基生长的小植株不论在株高、叶数、根数、根长、鲜重、及乾重均较其他培养基为佳;不含添加物之1/2MS培养基、及含香蕉的培养基次之,而在含马铃薯之培养基较差。

The effects of compositions on UV prinking ink,such as prepolymer,monomer,photoinitiator and pigment on curing rate,cohesive force,resistency and other properties were investigated. The range analysis and variance analysis method were applied to the assessment of results. The results based on orthogonal experiment design indicated that an optimum component composition of UV printing ink can be obtained from prepolymer PQ611,monomer A,photoinitiator B and active amime.
摘 要:探讨了预聚物、单体、光引发剂、颜料等组分对UV油墨固化速度、附着力、耐抗性等性能的影响,应用正交实验设计方法对UV油墨各组分种类进行选择,对正交试验结果做极差分析及方差分析,结果表明:根据预先设计的组分比例,采用预聚物PQ611,单体A,光引发剂B,活性氨为加速剂,获得性能较好的UV油墨。

Chemically pure elemental Al and CuO powder with an Al mass percentage of 20, 35, 57, 70 and 85 were milled respectively. The ball milled powders were analyzed by X-ray diffractometry and differential scanning calorimetry. When the amount of Al was under 20%, the reduction occurred only. When the amount of Al exceeded 20%, besides reduction, the synthesis reaction occurred simultaneously.
对Al含量在20%~85%范围内的Al/CuO进行高能球磨,采用X射线衍射进行物相分析,并对Al含量分别为20%和75%的试验分析了物相随研磨时间的变化,做了差示扫描量热分析,对比研究了固态还原反应与固态复合反应过程的异同。
