查询词典 CR

Background and objective Although marked progress has been made in the treatment of acute myeloid leukemia,about 20%～40% patients with AML failed to get complete remission after standard induction chemotherapy. Furthmore, approximate 70% patients in CR will die because of relapse or refractory to therapy during post remission chemotherapy.

研究背景及目的：尽管目前急性髓系白血病(acute myeloid leukemia，AML)的治疗取得了显著的进步，但仍有20％～40％的患者经标准诱导治疗未能达到完全缓解(complete remission，CR)，即使获得CR的患者，在巩固化疗后仍有70％左右复发或发展为难治性急性髓系白血病而治疗无效死亡。

In order to gain higher magnetic performance and solve air pollution problems in extraction process of Fe-Cr fibers,cupreous body of Cu-13Fe-2Cr in situ composite materials were corrupted by using chemical extraction .

为解决Fe-Cr纤维提取过程中容易造成空气污染的问题，使得到的纤维具有较高的磁学性能，采用化学萃取法腐蚀掉Cu-13Fe-2Cr原位复合材料中的铜基体，制备了Fe-Cr金属纤维；通过调整硝酸与双氧水比例抑制NO2的产生；通过改变清洗方式使纤维具有较高的磁性。

Experimental results show that the dielectric strength increases significantly when the Cr phase is selectively strengthened.

例如，CuCr触头合金是由Cu相和Cr相组成的，而CuCr合金在真空中的电击穿首先选择发生在耐电压能力较弱的Cr相的表面［4］。国外研究者也有类似的研究结果［5］。

Methods Fifty pairs of fresh colorectal cancer and homologous normal tissues were genotyped with Identifiler Kit and the mutations generated in cancer tissues were determined. The mutation rates, the numbers of locus matched without identical allele (A0), 1 identical allele (A1), or 2 identical alleles (A2) and the number of total identical alleles IA(subscript n were calculated. Frequency distributions of A0, A1, A2 and IA were compared among CR-N group, unrelated individual pairs and full sibling pairs. Discrimination functions were established for individual identification from tumor tissues with discriminatory analysis.

用Identifiler系统对50对新鲜结直肠癌组织及其身源正常组织组进行STR分型，计算CR-N组中变异STR基因座及全不同基因座数(A0)、半相同基因座数(A1)、全相同基因座数(A2)和共有等位基因数IA(下标 n，比较CR-N组、无关个体对组和全同胞对组中上述参数的分布差异，通过判别分析建立判别函数。

In this study, Fe and sodium dithionite solutions were added into Cr-spiked soils and their effects on the decrease of availability of Cr were investigated.

本研究旨在探讨将Fe或连二亚硫酸钠（Na2S2O4）等化学还原剂施於Cr污染之碱性土壤，降低有效性六价铬含量的效果。

Fe, Ni and Mn, in form of divalence, and Cr in form of trivalvence dissolve into solution.

蚀孔内发生金属的活性溶解腐蚀；Cr以三价离子，Fe，Ni和Mn以二价离子形式溶解；Fe，Cr的溶解量对孔蚀自催化效应有显著的影响。

In the presence of PD , the dissolution rates of Cr and Ni in 304 matrix decreased obviously, and the molar percentages by which various components in 304 stainless steel dissolved were different from those in the absence of PD. AAS data indicated that regardless of the presence of PD the dissolution of Fe, Ni and Mn took the form of divalence, while Cr dissolved in the form of trivalence.

PD对304不锈钢在盐酸中的腐蚀存在"选择性抑制"效应，能显著减缓Cr和Ni的溶解，改变各元素溶解的比例，导致耐蚀组分在电极表面富集。

All the Lewis base ion and molecule which can supply duplet to coordinate with Cr〓 as ligand. Cr〓 also has another special property, its hydrate will bond together to form multi-core complex compound by hydroxy glycidic when the concentration is properly.

含铬外加剂利用Cr〓的特点，在一定浓度下除了自身缩合形成多核络合物外，还可吸附在矿料表面，在加热条件下，与酸性集料表面的羟基缩合，通过氧桥与矿料表面键合。
