查询词典 donor

The United States is the largest donor, providing more than a quarter of the Fund's resources.

其中，美国是最大的捐赠国，提供了该基金超过四分之一的资金。

It was shown that the improvement of electric properties in 1%Eu-PZT can be attributed to Eu donor doping, which decreases the concentration of defects such as oxygen vacancies and holes, while the degradation in fatigue and leakage current properties shown in the films with more than 1mol% Eu dopant results from the apparently dominant acceptor doping, which increases the concentration of oxygen vacancies and holes.

结果表明，1mol％Eu施主掺杂，可以减少氧空位以及空穴等缺陷浓度，因此1％Eu-PZT薄膜的极化疲劳和漏电流特性得到明显改善；高于1mol％Eu的受主掺杂作用使薄膜中氧空位以及空穴等缺陷浓度增加，导致PZT薄膜电学性能恶化。

When a donor or an acceptor impurity is added to a semiconductor, we say that the material has been "doped".

当半导体中加入了施主感受主杂质，我们就说该物质"掺杂"了。

The donor impurity and grain boundary combustion-supporting agent containing acceptor impurity were added successively in the ceramic powder during ceramic powder preparation, both of them can also promote grain growing and semiconductive, and the combustion-supporting agent can be good to form insulation layer in oxidizing process.

采用一次性烧成技术研制了晶界层半导体陶瓷电容器，在瓷料配制过程中先后加入施主杂质和含有受主杂质的晶界助烧剂，两者在还原烧成时促使晶粒生长并半导化，助烧剂在氧化时有利于晶界绝缘层形成。

In the research of prescription, through the experiments we knew the influence from the Nb_2O_5 or Y_2O_3 single donor doped on high-temperature PTC ceramic, and got the curve graph drawing the resistivity and mixing quantity. In order to restrain lead volatilize and mix the rang of donors to neutralization the harmful acceptor impurity in raw materials, adopt the prescription design of Nb_2O_5 and Y_2O_3 double donors-doped. From the result, we know that regulation proportion of Nb , Y double donors, can make high-temperature PTC ceramics semiconducting, the pottery demonstrates good electric performance.

为了能够更有效的抑制铅挥发，并且使掺杂范围能够更好的调节，以"中和"原材料中的有害受主杂质，在配方设计中采用了Nb_2O_5和Y_2O_3双施主掺杂的配方，由结果可知，适当的调节Nb、Y双施主掺杂总量及Nb、Y掺杂比例，可以使高温PTC陶瓷充分的半导化，陶瓷表现出良好的电性能。

Result: In the 3852 cases of paid blood donor There are 7 curriers of HIV are detected and they are all paid blood donor in past. The infection status of the other 3 pathogens HCV, 323 cases (8.39%), HBV, 231 cases (6.00%), TP, 50 cases (1.30%).

结果 在检测的既往有偿献血员3852例中，共检测出HIV感染者7例；其他三种病原体的感染状况分别是：HCV感染者323例（8.39％），乙肝携带者231例（6.00％），梅毒感染者50例（1.30％）。

blood serums of the crowd are collected, antibody corresponded to the four virus examined by elisa、pa and colloidal gold strip. western blot is the confirmation test of positive for antibody of hiv. result: in the 3852 cases of paid blood donor there are 7 curriers of hiv are detected and they are all paid blood donor in past.

采集有偿献血员的血清，通过酶联免疫吸附实验、明胶颗粒凝集实验和胶体金实验来检测血清中的这四种传染病病原体的相应抗体，抗－hiv阳性确认实验是蛋白印迹实验。

The coordinated COD of 3 and 4 can be replaced by carbon monoxide to yield the corresponding dicarbonyl species [(C,N-pyN^C-R) M2]BF4 (14, M= Rh; 15, M= Ir). Ligand substitution of 11a by phosphines and azide causes the de-complexation of pyridinyl-nitrogen donor to generate the corresponding carbene rhodium complexes [(C-pyN^C-Mes)RhPR3] (17a, R = Ph, 17b, R = Et) and [RhN3] (19), respectively, indicating the labile nature of steric-hindered pyridinyl-nitrogen donor.

螯合错合物的吡啶配位，可以容易被σ-予体，如卤离子、叠氮阴离子、膦试剂，置换；但是铑与铱金属螫合物与π-酸试剂，如一氧化碳、异腈，则发生COD被置的产物14a与16；与三甲基亚磷酸酯反应时，COD及吡啶均会被取代而得到单芽的三铑-碳烯错合物18；双膦化合物则会取代铑金属上全部的配位基。

Their electrical and photophysical properties are characterized with different numbers of donor and acceptor, and the molecular band gap can be well-tuned by altering the number of donor and acceptor respectively.

藉由电化学实验中得知，不同数目的电子予体和电子受体，会有不一样之氧化电位和还原电位。利用此特性，分别调控分子HOMO及LUMO之能阶位置，有策略性的改变分子之能阶差，调控其电荷转移之放光波长。

While the Gog and Magog known today as the United States and Great Britain controls the nations of the world through the United Nations organization whose headquarted is the United States being the principal donor and sponsorer while the Great Britain controls the Common Wealth of Nations whose headquarters is in the United Kingdom being the principal donor and sponor.

虽然戈格和玛各已知今天的美国和英国控制了世界各国通过联合国组织的headquarted是美国为主要捐助国和sponsorer而大不列颠控制的共同财富，其总部是联合国在英国是主要捐助国和

In the negative and interrogative forms, of course, this is identical to the non-emphatic forms.

。但是，在否定句或疑问句里，这种带有"do"的方法表达的效果却没有什么强调的意思。
