查询词典 ions

A simplified model which considers the partially ionized plasma as hydrogen-like ions is presented. Classical electrodynamics theory is employed to study the action of ponderomotive force on bound electron and the effect of ponderomotive force on the generation of laser plasmas. A relation between generation of laser plasma and laser wave train length is obtained.

研究了pH值、温度、光照、金属离子和添加剂等对杨梅鲜汁中红色素稳定性的影响，结果表明：杨梅果汁中的红色素对酸碱度极其敏感，热稳定性差，耐氧化和还原性极差，防腐剂的消色作用较大。

In addition, the effects of metal ions on the weak interaction between ATP and TAME, or between ATP and analogues of L -arginine were studied.

这种识别作用的发生，对深入理解在ATP合成和水解过程中，ATP合酶中精氨酸残基如何起到"触点"的作用有一定的参考价值。

But to understand sentience, we ultimately must try to connect thought to the simplest components of the brain—to such things as acetylcholine, potassium ions, proteins, and water—and tell a story that extends from them to "The Well-Tempered Clavier."

但是要去了解情感，我们最终需要去尝试将思想连结到脑子里的最简单元件—像是乙酰胆素，钾离子，蛋白质和水—从而说出一个故事并能延伸到〝巴哈的平均律〞。

If there are no more quest ions,the witness may now stand domn.

没有更多问题的话，证人可以退席了。

Since xylenol orange interferes to determine some metal ions, such as iron, nickel, the author researched to determine them using EDTA.

6对二甲酚橙有封闭作用的金属离子如三价铁、镍，本文研究了用EDTA法测定它们的方法。

The liberated EDTA is titrated with zinc standard solution using xylenol orange-CPB as indicator to obtain a sensitive and clear end-point, Interference of ions is also studied.

释放出的EDTA用锌标准液返滴定（XO－CPB为混合指示剂），终点变化相当敏锐。

The characteristics of Eu2-xYxW2O9 phosphors were found to depend on the amounts of yttrium ions and calcination temperature.

在Eu2-xYxW2O9萤光体中，发光亮度会随著煆烧温度、Y3+的取代量增加而增加。

The surface zirconyl species as centers of negative charge compensated by sodium ions presents a property of ion exchange. mesoporous silica ; ZrMCM-41; synthesis ; molecular sieves

在本文中，作者使用中性条件和硝酸氧锆作锆源，在水热体系中把Zr原子引入其固架，合成出了ZrMCM - 41 ，发现该样品与文献 [4]，[5]报道的不同，存在明显的B酸中心。1 实验部分1 。1 试剂硅源：Na2 Si3O7溶

The single micronucleus and multi-micronucleus were observed at the interphase. The chromosome aberrational cells including chromosome fragment, lagging chromosome, chromosome bridge and circular chromosome were found during the mitosis. RAPD analysis of seedling genomic DNA variation in M 2 generation of three mutants showed their DNA sequences had changed. The result confirmed that the implantation of 7Li +3 ions could induce genetic mutation in wheat.

对幼苗根尖细胞学研究观察，获得单桥、双桥、桥断裂、落后染色体、三级、断片和微核等畸变类型；对已获得的小麦突变株，分别进行M2 代DNA分子的RAPD分析，结果发现DNA均发生变异，证明7Li+ 3 注入通过内靶核反应能够诱发小麦在分子水平上产生遗传变异。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。
