The quantitative relationship between the structure of artemisinin analogues and their antimalarial activity against W-2 was studied by Comparative Molecular Field Analysis.

采用比较分子力场分析法，将40个类青蒿素的抗疟活性作了定量构效关系的研究。

FITC can inhibit the antimonite-stimulated ATPase activity of ArsA and a combination of ATP and antimonite can completely protect ArsA from the inactivation of FITC. The Lys residue in the glycine-rich loop in ArsA is possibly one of the sites for FITC modification. Antimonite can induce the fluorescence resonance energy transfer between FITC and TRITC that separately labeled on different ArsA molecules.

研究还发现FITC对ArsA的ATP酶活性有抑制作用，ATP和SbO〓与ArsA的结合完全拮抗这种抑制，说明ATP和SbO〓与ArsA的结合能够引起ArsA产生一种完全不同于它们单独与其结合时的构象变化，从而使ArsA上FITC的修饰位点变得不易接近，同时ATP结合位点内的Lys可能是FITC在ArsA上的结合位点之一。

These paradoxes form the antinomic text tension as Lodge's critical theory has intruded his text creation.

第四章以洛奇代表作《小世界》为个案，证明了该文本不但有高雅文学话语与通俗文学话语、现实主义风格与实验主义技巧的对立，而且有戏剧性的反讽与严肃的关怀、建构的意图与解构的手法的调和。

A considerable GMR effect which stems from the significant difference of electron transmission in parallel and antiparallel magnetic configurations in the GMR device is found.

我们发现，由于电子隧穿平行和反平行磁构形的透射系数明显地不同，因而导致了显著的巨磁阻效应。

The molecular structure of ω-CTX SO3 is stabilized by three disulfide bridges and a short triple-stranded antiparallel β-sheet with four turns.

与其他ω-CTX溶液构象的比较指出它们的差别仅在于β-片层长度和β-转角类型不同。

With the adoption of the rate-sensitive constitutive relationship, it is asymptotically investigated the propagating tip fields of antiplane mode III crack under the condition of incompressibility, and the dynamics equations are obtained separately governing the stress and strain fields at the crack-tip.
