查询词典 Pf.

Most importantly, the LUMO energies of PFCN are around 1 eV lower than those of PF, which results in the decrement of EA about 0.9 eV, indicating that the 1,2-bis( p -phenylene)-1-cyanovinylene unit has significantly improved the electron-accepting properties of the copolymer PFCN.

更重要的是，PFCN和PPhCN的最低空轨道比聚芴低近1 eV，直接导致电子亲和势降低0.9 eV。这意味着含氰基亚乙烯基共聚物的电子注入能力大大提高。

Objective To investigate the effects of piperazine ferulate on TGF-β1-induced renal interstitial fibroblast activation, and to explore the mechanism of PF in the prevention of renal tubulointerstitial fibrosis.

目的 观察阿魏酸哌嗪对转化生长因子－β1(TGF-β1)诱导肾成纤维细胞表型活化的影响，探讨其抗肾间质纤维化的可能机制。

Convergence is stronger than divergence in the Polar Front Zone,indicating that a part of the converging water must come from the cold water transporting northward from south of PFZ and contribute to the formation and maintenance of the lateral temperature gradient of SAF.

极锋区(PFZ，指极锋PF与亚南极锋SAF之间的区域)中辐聚大于辐散，部分辐聚的水体必定来自极锋以南向北输送的温度更低的上层水，对SAF水平温度梯度的形成和维持做出贡献。

The locations and orientations of the Subantarctic Front, the primary Polar Front and Southern ACC Front in the ACC of the Southeast Indian Ocean can be identified more precisely by the current distribution derived from ADCP data than by hydrographic data, because these fronts are usually accompanied by strong currents, although the speed coinciding with the SACCF is less than that of the SAF and primary PF.

在东南印度洋远离海脊和海台的深海盆以及海脊和海台的走向与ACC主轴平行的海域，高涡动能主要由周期大于90天的变化产生。SAF在东南印度洋没有一致的季节变化。

The structure of prime submodules of free modules is depicted and a calculable formula about prime dimensions of free modules is given.

对自由模的素子模是进行了刻画，给出了自由模的素子模的结构为(PF，u1，u2，…，us)，且给出了自由模的素维数的计算公式D=dimA+rankF-1。

Results Same conservative sites and key catalytic sites existed among SjLDH and LDHs from other species. Similarity of SjLDH compared to CsLDH, TvLDH and HsLDH was 75%, 17%, 58%-60% respectively. Phylogenetic analysis demonstrated that the evolution relation between SjLDH and DmLDH was closer than the relation between SjLDH and CeLDH, the relationship between SjLDH and HsLDH-B,-C was closer than HsLDH-A. Three trans-membrane regions were found, the region of 98aa-106aa in three hydrophilia regions located outside of membrane was inferred as the major antigen epitope. This antigen epitope had significant difference with LDHs from protozoon （ Pf ., Tg ., Tv .） and had 1-3 amino acid residue difference with MmLDH, HsLDH-A,-B,-C, and was the same with CsLDH. One of the key catalytic residues and substrate binding loop were located in this region. Tertiary structure demonstrated that 98aa-106aa was on the surface of the protein and formed a substrate binding loop, other two key catalytic sites were at the position near the loop.

结果 SjLDH与其他物种的同源序列含相同的保守位点及催化活性位点，与华支睾吸虫LDH同源性最高为75％，与阴道毛滴虫LDH同源性最低为17%，与人LDH（HsLDH-A，-B，-C）的同源性为58%~60％； SjLDH与果蝇的进化距离较秀丽隐杆线虫为近，3种人LDH中与HsLDH-B、-C的进化距离较HsLDH-A为近；该蛋白具有3个跨膜区域，3个高亲水性区域，主要的线性表位98aa~106aa位于膜外，与原虫LDH相同区域差异显著，而与其他LDH有1~3个氨基酸的差异，关键催化位点之一及底物丙酮酸结合区域位于该区域，蛋白质同源模建分析表明该区域位于蛋白表面形成环状结构，3个关键催化位点位于该区域或在其附近。

The results of the studies on fluorescence quenching by anionic quencher KI also confirmed the intercalative binding of PF with DNA.

阴离子KI的荧光猝灭实验进一步证实了酚藏花红与DNA之间的嵌入作用。

Nearly all of it is being channelled through UN agencies and NGOs to prevent it falling into Zanu-PF ' s rapacious hands.

几乎所有的援助都是通过联合国机构和非政府组织，这样以防止它们落入民盟党贪婪的手中。

Results Beginning from alveolitis, PF in different diseases has similar pathological changes in a progressive and reparative process.

结果不同病种的肺间质纤维化性改变都是从肺泡炎开始，在发展和修复过程中导致的肺纤维化倾向有共同之处。

But we don't care about Battlegrounds.

但我们并不在乎沙场中的显露。

Ah! don't mention it, the butcher's shop is a horror.

啊！不用提了。提到肉，真是糟透了。
