查询词典 ion

Atom, molecule or radical can be excited to a specific intermediate state by absorbing m laser photons, then the parent ion can be produced by absorption of another n laser photons. The ion yield can be increased drastically due to resonant absorption, comparing with the ion yield in non-resonant absorption. This multiphoton process is usully called Resonance Enhanced Multiphoton Ionization. REMPI technique plays an important role in detecting the high electronic excited states of atoms, molecules and radicals.

原子、分子、离子或自由基在同时吸收m个光子从下态共振跃迁到中间态后再吸收n个光子使其电离的过程中，下态和中间态的多光子共振吸收使得产生的离子信号强度比相应的非共振多光子电离得到的离子信号强度有很大的增强，该过程称为共振增强多光子电离REMPI。

According to experimental results and etiopathogenisis and pathology of osteoporosis , and analyzing review investigation on hepcidin、associations of bone metabolism and iron metabolism and relations of ferri ion and calcium ion,we can make conclusions as follows: 1、We applied single manmade intervention approach to induce osteoporosis model in this study, there was no other influential factor. In the termination of test , rats bone density and bone histological anatomy indicated that osteoporosis model was creditable,meanwhile hepatic functional enzyme and hepatic microtome section demonstrated that hepatic function had noci-influence induced by medicinal herbs resource. Accordingly, we could believe that hepatic hepcidin gene expression and serum hepcidin contents can represent internal iron metabolism changes at selected test time. 2、In this investigation, different findings between test group and control group indicated that:according to changes of hepcidin gene expression measured by RT-PCR and changes of serum hepcidin contents determined by ELISA kit , there were correlations between hepcidin and rat osteoporosis model induced by retinoic acid. 3、Under the condition of this investigation,there was a interactive hypothesis as follows: Hepcidin iron metabolism←→ferriion←→calcium ion←→osteoporosis.

根据本次实验结果，对骨质疏松的病因病理的认识及铁代谢与铁调素、骨代谢与铁代谢关系、铁离子与钙离子的关系系列研究的回顾，经分析得出如下结论：1、本研究骨质疏松模型采用单一人工干预方法，没有其他影响因素；实验结束时大鼠骨密度、骨组织学检查表明骨质疏松形成，同时肝脏功能酶和HE切片显示肝脏功能未受药源性产生明显损伤性影响；因此，同期不同时间组大鼠肝脏铁调素基因表达、血清铁调素含量可以代表体内铁代谢不同时间的变化。2、在本研究中，模型组与对照组研究结果的差异表明：铁调素基因RT-PCR变化、血清铁调素ELISA测定含量变化与维甲酸制作的大鼠骨质疏松模型形成有实验相关性。3、在本研究平台下，形成了一个互相影响的假设图：铁调素←→铁代谢←→铁离子←→钙离子骨质疏松。

objective we start with clinical research to explore the ability and mechanism of ion conduction with chinese herbs to curing ovulatory obstacle.methods adopting the methods of clinical observation random contrast.select the cases of ovulatory obstacle dividing randomly into two groups:therapeutic group and control group,the patients of therapeutic group using ion conduction with chinese herbs with act'on nourishing blood and promoting blood circulation to dissipate blood stasis when follicle grow up to 1.4cm.we take the decoction of jia jian tao hong si wu tang conducting the unilateral lower abdomen which has the dominant follicle,treating continuously for 4～8 days and observing ovulation.the patients of control group inject hcg 10000unit when follicle grow up to 1.8cm and observing ovulation.appraising two groups ovulated rate and pregnancy rate,and detect fsh、lh、e2、p at sixteen to eighteen days of menstrual cycle.results ion conduction with chinese herbs can significantly inspires ovulation and its effection is evidently higher than control group and has a higher pregnancy rate,no side effect of ovarian hyperstimulation syndrome.conclusion ion conduction with chinese herbs has significant function on inspiring ovulation.the target effection of treating ovulatory obstacle is exact.this method has a ovulated rate and higher pregnancy rate.

采用临床观察、随机对照的方法，选择排卵障碍的患者，随机分为治疗组和对照组，治疗组在b超监测卵泡生长达到1.6cm时，给予具有养血、活血化瘀作用的加减桃红四物汤水煎剂，用离子导入仪将中药水煎剂导入有优势卵泡的一侧少腹部，连续治疗4～8时天，同时连续监测卵泡排出情况。对照组在b超监测卵泡达到1.8cm时，开始采用hcg10000u肌注，连续b超监测卵泡排出情况。评价两组排卵率及受孕率，同时在月经周期的第16～22天抽血查fsh、lh、e2、p。结果运用离子导入的方法将具有促排卵作用的加减桃红四物汤水煎剂导入有优势卵泡的一侧附件，其促排卵的作用优于用hcg肌注促排卵，而且受孕率高，无卵巢过激综合征之虞。结论中药离子导入具有显著的促排卵作用，其治疗排卵障碍的靶向作用确切，排卵率及受孕率高。

The ion concentrations were studied in both four snow pits on Hami Miaoergou FlatTopped Glacier and one snow pit on Haxilegen Glacier No.51 of Kuitun river in eastern Tianshan Mountain, and both snow pits were retrieved in 2004. The results show that the Ca2+, NO-3 and SO2-4, particularly Ca2+, are major ions in the snow of snow pits in both ablation and accumulation area and also in the ice of snow pits in accumulation area on Hami Miaoergou FlatTopped Glacier, where the relationships among major cation concentrations in snow of snow pits can be revealed by ion concentrations in the ice of snow pits, but the correlation between ion concentrations in the snow of snow pits and elevation is not obvious, which probably can be attributed to the narrow span of elevation and sparse snow pits on glacier. However, the good correlation between ion concentrations in the ice of snow pits and elevation indicates that the elution process weakened gradually with the elevation rise and temperature decrease.

对2004年获取的天山奎屯河哈希勒根51号冰川1个雪坑和哈密庙尔沟平顶冰川4个雪坑的离子浓度特征进行了研究，结果表明：Ca2+、NO-3和SO42-是哈密庙尔沟平顶冰川雪坑雪层和积累区雪坑底部冰中的主要离子（尤其是Ca2+），其雪层中的主要阳离子关系可在底部冰中得以较好的反映，但雪层中各离子浓度与海拔的相关性不明显，可能与海拔的跨度较小和挖取的雪坑较疏有关；雪坑底部冰中的离子浓度与海拔间明显的相关性说明淋融作用随着海拔升高、气温降低而逐渐减弱。

It was observed that not only histidine, but also histidine-Co and histidine-Ni could induce and substitute some Cu and Zn from Cu_2Zn_2SOD, eventually influence the activity of this metalloenzyme. Histidine- metal ion complexes have stronger ability than histidine to displace the bound metal ion from SOD. In addition, the amount of foreign metal ion binding to the SOD was less than that of metal ion lost from SOD. It obviously means that there was apoenzyme in the solution.

实验结果表明： Cu2Zn2SOD酶不仅与组氨酸，而且还可以与组氨酸－CoⅡ）和组氨酸－Ni(Ⅱ相互作用，Cu2Zn2SOD酶中的部分Cu和Zn被诱导和置换出来，并相应地影响了酶的活性；组氨酸－金属离子配合物的作用比组氨酸强，酶活性降低也更明显；酶中结合的外来金属离子的量比从酶上被诱导和顶替下来的金属离子的量要少，说明在溶液中有脱辅基酶的存在。

X=0, 11, 22, 33, 44, and 55 borophosphate glasses series have investigated, and it is found that:(1) both the covalency bonding between Yb〓 ion and oxygen ion and the asymmetry in local structures surrounding Yb〓 ion have strong effects on integrated absorption cross section ∑〓 and emission cross section σ〓 of Yb〓 ion in borophosphate glasses;(2) the borophosphate glasses and borate glasses appear superior as Yb-gain media to the phosphate glasses, although the phosphate glasses have been demonstrated as the most appropriate Ndgain media.

It is shown that in solution the ion pairs can exist in such different forms as contact ion pair, solvent-separated ion pair or free solvated ions. Solvent polarity influences not only the spectral properties of different forms, but the equilibrium between them as well, leading to change of physicochemical properties of the ion pairs.
