Results IC50 that catechin eliminated O(superscript - subscript 2) and OH was 6.16, 0.59 g/mL respectively, and the eliminating ability of catechin was much stronger than that of the extract from liquorice, rosemary, grape pip, giant knotweed and ginkgo leaf.

The conductivity is lineally increased while the decrease of the diameter of nanowire. Meanwhile, the conductivity of oxidized state and reduced state doped with ClO(superscript - subscript 4) ion is lower than that of partial oxidized state by two order of magnitude.

尚未观察到反向击穿现象，可能原因是，在一定的反向偏压下的离子脱嵌使得它由部分氧化态转变为还原态；电导率随纳米线直径减小而线性地增加；以ClO(上标-下标 4)不离子掺杂的氧化态和还原态比部分氧化态的电导率低二个数量级。

The results show that when the depth gradually reduces, pH values gradually increase, but conductivities and (superscript – subscript 3) content gradually reduce. There are also obvious differences between the groundwater in loess, alluvial deposit and acidity rock in the south of Chang'an, which relates to the depth, the characters of loess, the lixiviation and the evaporation. The element content of groundwater is high in the loess tableland, so it's fitter for drinking than the groundwater in the Cuihua mountains, which is of acidity and low element content.

结果表明，长安南部黄土塬随着层位的降低，pH值有逐渐增大趋势，电导率和HCO(上标–下标 3)含量有逐渐减少的趋势；黄土地下水、冲积层地下水和酸性岩石地下水的化学成分存在明显差异，这与其理深、地层性质、溶滤与蒸发作用不同有关；长安南部少陵源黄土地下水元素含量较高，比呈酸性、元素含量低的翠华山泉水更适于饮用。

The author gives two methods to specify the scale interval by using fitting of three—broken—line as well as statistical hypothesis testing based on the estimate of the derivative of the double logarithmic curve.

由于实际动力系统的混沌吸引子其自相似性只能在一定的尺度范围内存在，文中给出了两种无标度区间的确定方法以正确地估计吸引子的分形维数，即三折线拟合方法和通过直接估计双对数曲线上每一点的导数并利用统计假设检验方法确定合理的无标度区间。

The results show that after partial substitution of La(superscript 3+) with K(superscript +), the structure and component of La(subscript 1-x)KCoO3 will be changed.

结果表明，K部分取代La(上标 3+)会影响La(下标 1-x)KCoO3的晶体结构和组成。

Nanometer composite S2O(superscript 2- subscript 8)/SnO2-TiO2 was used as a catalyst in α-pinene isomerization.

首次将纳米复合S2O(上标 2-下标 8)/SnO2-TiO2用于催化α-蒎烯异构化反应。

The dissertation gives a brief description about the developing situation and control theory of robot firstly, and then the underlying idea and characteristic of CTC are introduced in detail. Subsequently three classes of control strategies with compensation control structure which are based on CTC are proposed. The overall idea is that the system of robotic manipulators is decomposed as two parts: one is nominal system with perfect knowledge of dynamic model and the other is system with uncertainties. CTC is used to control nominal system. For uncertainties system, we utilize the regressor of robotic system or bounding function on uncertainties to design different compensation controllers. The outputs of the two parts control the robotic

本论文首先介绍机器人的发展概论概况，然后对计算力矩控制算法的基本思想和主要特点作详细的阐述，紧接着探讨基于计算力矩结构不确定性机器人的补偿控制方案，其中的基本思想都是将不确定性机器人系统分解成标称系统和不确定系统：对于标称系统，采用计算力矩控制；对于不确定系统，利用机器人系统的回归矩阵或集中不确定性上界的包络函数，设计不同的补偿控制器。

Case law rule allows unilateral withdrawals of inadvertently erroneous bids from the bidder. U.S. federal procurement system, deriving from contracting law, permits bid correction or withdrawal before award and reformation or rescindment after award under certain circumstances.

於美国契约法下，判例上即允许投标厂商有主张单方计算错误而撤销契约，而美国联邦采购制度主要之规定均系依循美国契约法而来，亦在一定要件下允许厂商於决标前可更正投标或撤销投标；於决标后，亦可重新形成契约或撤销契约。

In carbon and nitrogen culture medium, glucose and NO(superscript – subscript 3)-N were positive to sclerotium forming of R.

cerealis菌核形成的适宜温度为18~25℃，适宜pH值为5.0~7.0，暗培养或光暗交替培养有利于菌核形成；在碳、氮营养中，葡萄糖和NO(上标-下标 3)-N最有利于R。

The O-2 production rate, H2O2 content, superoxide dismutase, peroxidase, ascorbate peroxidase, catalase and polyphenol oxidase and MDA content of petal of two tree peony cultivars 'Luoyanghong' and 'Huhong' during florescence and flower senescence were detected by the methods of conuentional biochemistry. The relationships among MDA content and others index were analyzed by the simple correlation coefficient, stepwise regression and the path-coefficient.

测定"洛阳红"和"胡红"2个牡丹品种开花和衰老过程中花瓣膜脂过氧化产物丙二醛、超氧自由基O(上标–下标 2、过氧化氢(H2O2)的含量及超氧化物歧化酶、过氧化物酶、抗坏血酸过氧化物酶、过氧化氢酶、多酚氧化酶的活性，并采用简单相关分析、逐步回归分析和通径分析等方法研究MDA含量与其他指标的关系。

In the negative and interrogative forms, of course, this is identical to the non-emphatic forms.

。但是，在否定句或疑问句里，这种带有"do"的方法表达的效果却没有什么强调的意思。
