查询词典 donor

Their electrochemical behaviors are similar to that of TTF, so they should be good donors for conducting materials. They are novel monosubstituted asymmetric TTF-π-A donor molecules with TTF cores, which should be good donors for molecular conductors or OFET potential application.2. The tuning of the charge-transfer of TTF-PEO by solvent was realized forming the mono- and dication complexes_2CuBr_4 (5) and_2(CuBr_4)_2·CH_2Cl_2·CH_3CN (6) in the triclinic Pīand the orthorhombic Pbca space group, respectively.

同时每种化合物均为单取代的非对称分子，因此该类化合物在非线性光学材料领域可能有潜在的应用。2、通过改变溶剂的方法方便地实现了调节TTF-PEO的电荷转移量为+1和+2，分别合成出化合物_2CuBr_4 (5)和_2(CuBr_4)_2·CH_2Cl_2·CH_3CN (6)，晶体结构分析表明它们分别属于三斜的Pī和正交的Pbca空间群。

Doped high consistence Co can't increase the density of defect levels. ZnO doped Fe is different from doped Mn or Co totaly, the density of photoelectrons anddefect levels aren't reduced obviously. It's probably related the valence of Fe in crystal,general think trivalence of Fe, and form donor levels in ZnO.

Fe掺杂的ZnO完全不同于Mn、Co掺杂，其光生电子密度没有因掺杂出现明显的降低，即缺陷能级密度没有降低，这可能和掺入ZnO所呈现的价态有关，一般认为Fe为三价态，在ZnO中形成施主能级。

The donor in the study had a history of homelessness and alcohol use and was hospitalized for cerebral vasculitis. He had no known history of TB, and previous tuberculin skin tests had been negative.

这项研究中的捐赠者有无家可归与酗酒的病史，且因为脑血管炎住院；他过去没有已知的TB病史，且过去的结核菌素检验是阴性的。

My blood is type ＂O＂, so I'm a universal donor.

我的血型是"O"型，所以我是一个万能输血者。

She heard Ben needed blood, says she's a universal donor.

她听说我们需要血液，说她是个万能供血者。

These methods provide promising way to make universal donor blood and may have significant application in transfusion medicine.

这两种修饰方法为制备通用型血供临床输血开拓了崭新的途径，具有重要意义。

O-negative is the universal donor, it's in the ballpark, it's not a match.

o型阴型血是万能的，大致上合适，但并不匹配

But type O is called the "universal donor" since it doesn't have any antigens that would set off the body's defense system.

但是O型血被称为"万能供血者"是从它所拥有的抗原不会破坏人体的系统所得名的。

Exactly. But type O is called the "universal donor" since it doesn't have any antigens that would set off the body's defense system.

完全正确。而O型血之所以被称为"万能血"，是因为它没有任何抗原，不会和身体的防卫系统相抵触。

JACK: O negative is universal donor. It's in the ballpark, it's not a match.

O 型阴性是万能输血者，但只是相近，而不相配。

I didn't watch TV last night, because it .

昨晚我没有看电视，因为电视机坏了。

Since this year, in a lot of villages of Beijing, TV of elevator liquid crystal was removed.

今年以来，在北京的很多小区里，电梯液晶电视被撤了下来。
