查询词典 donor impurity

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。

The catalyst includes: supported Ziegler-Natta catalyst of titanium halide compound and organic electron donor compound supported with MgCl2 alcoholate carrier; aluminoxane prepared with trialkyl aluminum and water; and one kind of organic electron donor, such as organosilicon compound R2Si(OCH3)2, where R is phenyl, isopropyl, isobutyl or cyclopentyl.

该催化剂包括，a一种负载型的Ziegler-Natta催化剂，即将卤钛化合物和有机给电子体化合物负载在氯化镁醇合物载体上得到的固体催化剂，b一种通过三烷基铝与水反应而制备得到的铝氧烷和c一种有机电子给体，如有机硅化合物R 2 Si(OCH 3 ) 2 ，其中R为苯基、异丙基、异丁基或环戊基。

The activated donor-type NK cells could prevent gVHD and produce significant GVT effects and also resulted in greater hematopoietic reconstitution if they were at the initial stage of allogeneic BMT in mice. Thereafter, the activated donor-type NK cells were detrimental and could exacerbate the subsequent GVHD, these results also demonstrated that GVT and GVHD could be dissociable phenomena.

①在小鼠异基因骨髓移植的初始阶段，输注供鼠的活化NK细胞能促进造血重建，预防GVHD并同时增强移植物抗肿瘤效应；输注骨髓细胞之后，输注供鼠的活化NK细胞则起到加重GVHD的不良作用；②GVT和GVHD是能够被分开的。

While the donative contract is the result of the same intention of the bilateral litigants, the donor gives his/her property gratuitously to the donee and the latter accepts the donation. The basic point of the two is both produced by the donor, establishing a certain right for himself/herself, and making the donee have the right to get something free.

而赠与合同是双方当事人意思表示1致的结果，即赠与人将自己的财产无偿给予受赠人，受赠人表示接受赠与的合同。2者产生的基点都是由赠与人引发的，为自己预先设定某种义务，而赋予对方当事人无偿取得某物的权利。

After geometric optimizations of the isolated donor and acceptor, the ionization potential of the donor and the electron affinity of the acceptor have been calculated.

通过孤立给体和受体的几何构型优化，计算了给体的电离能和受体的电子亲和能。

Objectives: Through studying the distribution of Sppan acetic ether extract in donor's hearts of rats and its effect on IL-1β in blood, to approach the distribution target ability of sappan in donor's hearts, and its possible immune resist mechanism.

目的：通过研究苏木乙酸乙酯提取物在同种异位心脏移植大鼠供体心脏的分布情况和对小鼠外周血IL-1β活性影响，探讨苏木免疫活性部位在供体心脏分布的选择性及其免疫抑制作用机理。

In the operation,some important techniques,such as hypothermic injection,mode and position of anastomosis of the donor vessels with the recipient ones ha-ve been improved.Methods to establish and observe the extrasomatic blood circu-lation of the donor kidney were recommended in this paper.

对于手术至关重要的低温灌洗途径的选择、供体血管的解剖及与受体血管的吻合方式和部位等解剖学技术逐步进行了改进和完善，介绍了供肾体外血循环的建立和观察方法，提出了保护肾上极动脉的初步意见。

Racing to find a heart donor in time to treat Henry before the infection kills him, House finds an organ donor who's been declared unfit due to a mysterious illness.

House於医院内找到一名可捐赠器官的女子，可是她生前却患上神秘疾病，令House不敢随便把其心脏移植到Henry身上。

The greater the volume of donor is, the smaller the ionization potential of donor is, the more difficulty is to form a CT complex.

体积越大电荷转移络合物越难形成；电离势越小，电荷转移络合物的最大吸收峰越红移，但是形成络合物也变得困难

Based on the above experimental results, we proposed that the exciplex formation also depends on the third factor, that is the interaction between the side-groups of donor and acceptor, besides the ionization potential and electron affinty of donor and acceptor.

因此，激基复合物的形成除取决于两个分子的电离能和电子亲合力大小外，还依赖于另一个参数，这就是分子侧基之间的相互作用力。
