Then, the approximate absolute gradient magnitude at each point can be found.

然后，每一点处的近似绝对梯度幅值就可被发现。

This discretization scheme replaced the gradient magnitude with the absolute value of the difference and omitted an item of the original model. The smoothing velocity and effect are affected by these simplifications according to the analyses of this paper.

这个离散格式用差商代替梯度，并略去了原模型的一项，本文通过理论分析发现这些简化影响了平滑的速度和效果。

The criterion is kind of a gradient threshold of the acceleration over time.

因此， 可以区分有巨大动态惯性的快速度事件，力量平衡的即时变化，甚至轻微的变化。

Methods Protein in blood and urine was precipitated directly by acetonitrile with acetanilide was used as the internal standard using Agilent Zorbax SB-Aq column (250 mm×4.6 mm, 5 μm).

以乙酰苯胺为内标，血液和尿液用乙腈直接沉淀蛋白，采用Agilent Zorbax SB-Aq(250 mm×4.6 mm， 5 μm)色谱柱，流动相选用水（含0.12%三乙胺和0.12%乙酸）和乙腈的混合溶剂梯度洗脱，流速1 mL/min，检测波长254 nm。

Methods: The mobile phase consisted of acetonitrile and water was used as gradient elution for separation with HPLC.

采用HPLC法，以乙腈－水溶液为流动相进行梯度洗脱。

The acidophile s composition and community structure in the sediment was studied with 16S rDNA clone library and denaturing gradient gel electrophoresis.

采集了酸性矿山废水区域酸性沉积物样品，运用16S rDNA克隆文库技术和变性梯度凝胶电泳技术，研究了沉积物中的嗜酸菌类群以及它们的群落结构。

Based on the acoustic absorption theory of microperforated panel and by the means of the theoretical analysis and emulation, the paper focuses on the acoustic characteristic including acoustic impedance, frequency and acoustic absorption coefficient of microperrforated panel working in the combustion chamber which has high temperature and great temperature gradient.

摘要根据微穿孔板吸声理论，采用理论分析和仿真的方法，着重讨论微穿孔板在温度梯度下的声阻抗、共振频率和吸声系数等声学特性，分析其受温度影响变化的机理。

We have studied the micro-structures of trumpet shells,actinia,skin and bamboos, and the bionic design principles and methids for integrated coatings, which inclde gradient coating,duplex coating,composite coating,hybrid coating,super lattice coating, were presented by this group.

研究了海螺壳、海葵、荷叶、皮肤与竹等的微结构，提出了整合涂层（包括梯度涂层、二元涂层、复合涂层、混合涂层、超晶涂层）的仿生设计原理和方法。

There are many difficulties in getting parameters when using Q system. In addition, the compound of strike, angle of gradient and discontinuities were not taken into consideration.

根据分级结果对比发现，Q系统具有分级指标获取困难的特点，且未能考虑边坡走向、坡角与结构面组合情况及坡高等因素对边坡稳定性的影响，难以适应边坡工程中稳定性评价的要求。
