查询词典 potential theory

The experimental results showed that the corrosion rate in this system is so low that it can meet the condition to be used in sealed batteries. It was also found that aluminum keeps active to some extent in a wide potential range and its discharge potential is near to that in aqueous solution. The sharp increase of discharge potential, which led to the end of discharge, was probably caused by the deposition of discharge products on aluminum surface.

实验结果表明这一体系中的腐蚀速率极小，以致于可以满足密闭电池的要求；纯铝在这一溶液中可以在相当宽的电位范围内保持一定的活性，放电电位与水溶液体系相近；放电后期电位迅速上升的可能原因是放电产物在表面的堆积。

The problem is how to consider the relativistic corrections to this potential. Adopting the assummation that the quark interaction is the sum of the usual one-gluon direct exchange and the mixture of linear scalar and vector potentials, we structure the relativistic corrections of order v2/c2to the Cornell potential, including the annihilation potential for the quark and antiquark of the same favors which plays the same role with the one-gluon direct exchange at short distances.

采纳库仑势源于单胶子直接交换，而线性禁闭源于标量和矢量的混合，同时考虑在短程区域与单胶子直接交换起同样作用的同味正反夸克的湮灭，构造了静态夸克-反夸克势到v~2／c~2级次的完全相对论修正，并拟合计算了重介子偶素的能谱，讨论了相对论修正对重介子偶素能级分裂的作用。

Objective: This study investigated olfactory function disorder in Canadian potential AD patients through measuring the detection threshold and recognition threshold, of the potential AD patients and the matched controls by Five Odorants Test; and evaluated whether the senile plaques, neurofibrillary tangles and neuropil threads , which were the typical pathological changes of AD, presented in the olfactory mucosa of potential AD patients.

老年性痴呆中有75%为阿尔茨海默病(Alzheimer's disease， AD)，AD 是一种神经细胞退行性疾病，原因不明，临床以进行性记忆丧失和后天获得的知识丧失，病程逐渐发展直至完全丧失生活能力为特征。其病因是多原性的。尽管AD 的描述已达90 年之久，但要在早期检出此病仍是一个难题，所以，改进其临床诊断程序、途径非常重要。当今广泛用于AD 诊断的诸多标准中均未明确提及嗅觉的改变，然而众多国外文献资料表明，几乎所有的AD 患者发病早期甚至在临床前期即表现嗅觉识别阈的改变，可见对此深入研究有助于AD 患者的早发现、早诊断。

This paper firstly analyses the limitations of traditional potential field methods in dynamic environment,and based on this analysis,the traditional potential field is improved by introducing the concept of velocity potential field .

分析了传统势场法在动态环境下的不足，并在此基础上引入了速度势场的概念，改进了传统的势场函数，推导出新的引力函数和斥力函数。

The presence of polarized potential is a ge neral property of the existence of an oil/gas reservoir. The whole oil/gas reser voir together with its diffusion-flowing belt can be taken as the source of the potential field, and the polarized potential can be described by a model of pol arized dipole.

油气藏存在极化电动势是共性，可以将整个油气藏、扩散带和扩散流动带作为场源，其极化电动势可用极化偶极模型描述。

Water potential may be defined as the chemical potential of water in a biological system compared to the chemical potential of pure water at the same temperature and pressure.

可以将水势定义为生物体系中的水的化学势，区别于纯水在相同温度和压力下具有的化学势。

The system non-optimum theory is a branch of systems science , which is developing recently. This paper is devoted to discuss the theory and practice, and to give an overview of the potential applications of the theory.

"系统非优理论"是一门正在萌芽中的系统科学：本文在[1]的基础上进一步论述了它的理论问题和实践意义，同时对它的应用前景进行了展望。

It is different from the Hoskins potential vorticity theory to explain the positive potential vorticity abnormal in upper level and the positive feedback of cyclone in lower layer which the plateau is a strong warm source that the heating effect is stronger than the warm air advection. The superadiabatic state is frequently appears over the plateau, it would be favorable to the development of the cyclonic circulation.

与Hoskins用位涡思想来阐述高层正位涡异常与低层气旋的正反馈作用不同的是，夏季高原本身是巨大的热源，这种加热甚至比暖平流加热还强；高原上经常出现"超干绝热"现象，这将使得高原上的气旋性环流加强幅度比其他情况下更大；由于高原地形的抬高使得从高原到上层扰动的气层厚度小于Rossby穿透高度HR=fL/。。。
