One has the ability of photo-cleavage of DNA and another one as potential anti-cancer drug has the ability of oxidative cleavage of DNA. 1. As for the first system, a new ligand----Tpphz is used as the intercalator of the targeted compound. The 〓 is synthesized and characterized by elemental analysis,〓H NMR, molar conductivity, AgNO〓 titration, UV and fluorescence spectra.

核酸的光切割方面，我们选择了近年来新发现的一个配体Tpphz作为目标化合物的插入配体，合成了新颖的〓单核配合物，并通过元素分析、〓H NMR、摩尔电导测定、中心离子滴定法、紫外光谱和荧光光谱对此化合物进行了详细的表征。

All glassware was covered in aluminum foil and muffledfor at least 4 h in a 500 _C muffle furnace to remover esidual organics.

所有玻璃器皿在铝芯和muffledfor至少4 h被盖了在对去膜剂esidual有机物的500 _C套炉。

In this paper, it is shown that the increment of the plasma confinement time without consideration of radiation losses is a good scale for evaluating the plasma confinement improvement during the L-H like transition induced by electrode bias in tokamaks, if the ratio of the radiation power to the total loss power in the transition changes evidently.

辐射下降表明进入等离子体的中性粒子通量减少。这是中性粒子再循环的减小而造成的。同时，边缘密度和边缘温度下降，中心温度上升，约束得到改善，能量约束时间增加。径向电场是控制托卡马克等离子体从L模过渡到H模的关键因素。如果径向电场足够强，极向ExB旋转产生很大的剪切，剪切能够抑制边缘湍流1j。

He went on to theorise that the rather weedy-looking semi-circular rods aat H above would be liable to bend, leaving a closed door in the path of the oncoming piston.

他接着就推论，相当杂草前瞻性的半环棒的学能测验上文H会被弯曲，留下了封闭的大门，在路径的迎面而来的活塞。

As a result, the redistribution of charge density by change of P-O and H-O distance and the subsequent rotations of the PO4 tetrahedra can lead to the driving force of the ferroelectric behaviors.

结果，通过P-O 和 H-O的距离改变电荷密度的再分布和PO4四面体的顺序旋转导致了铁电性的产生。

首先应用一种简单的代数方法生成了O-H型网格，然后，将其剖分为四面体网格，从而完成了简化航天飞机跨音速绕流的数值模拟。

However if h is allowed to evolve freely to maintain a constant number of neighbours in SPH summations , such unwanted effects can be avoided and accuracy improved .

若随时调整h的值使得SPH方法计算粒子的邻近粒子数总和保持不变，则可以避免这种有害的影响，使准确性得到提高。
