中国律师的定性很是模糊,有许多学者对律师的评价不是很高。诚然,要评价某个现象存在的好坏定然要将其放入一个特定的环境下,笔者觉得现阶段对律师的这一描述有失偏颇。  相似文献

折旧对项目评价指标影响的比较分析   总被引:1,自引:0,他引:1  
折旧作为工程项目现金流量的构成要素,其大小对工程项目的经济性评价有很大影响.对于同一个项目,采用不同的折旧方法提取折旧,可得出不同的评价指标.本就三种折旧方法对项目评价指标的影响进行了比较分析,指出折旧方法的选用,都是由利率和资产有效寿命期末残值与原值的比率确定的.  相似文献

提出了一种可用于嵌入式ASR系统的语音/噪声分类的新方法,该方法利用一个噪声模型,对每帧信号的评价值进行语音/噪声分类.实验表明,该方法可以有效地区分语音和噪声,并表现出在各种噪声环境和不同信噪比条件下的鲁棒性.该算法已经集成进一个ASR系统,并在Corn-paq iPAQ上进行了测试,其计算代价不到整个系统代价的10%.  相似文献

针对立铣加工过程中影响加工精度、效率和刀具寿命的切削颤振现象提出切削力矢量轨迹分散值评价法,并与传统的快速富里叶变换法(FFT)进行比较.用FFT分析时,需要预先采集大量数据,难于对机床加工过程实时控制;用切削力矢量轨迹分散值的计算方法,仅对机床主轴一个回转周期中的切削力信号进行采集,通过时域分析,快速评价机床的切削状态,可作为自动化加工过程实时监控的手段.  相似文献

心理动态特征评价基准的研究   总被引:2,自引:2,他引:2  
首先对心理动态特征进行了定义,然后通过对中国人的UK心理测验的结果进行随机抽样,利用最小二乘法确定了一种对心理动态特征进行有效评价的评价基准.该评价基准不但能反映心理动态特征的共性,还能根据被测者的UK作业量曲线方便地计算出被测验者的评价基准曲线,从而对受测者进行心理动态特征的评价.最后通过一个具体事例对该评价过程做了说明.该方法也可以应用到uK心理测验的数据自动化处理中。  相似文献

Language markedness is a common phenomenon in languages, and is reflected from hearing, vision and sense, i.e. the variation in the three aspects such as phonology, morphology and semantics. This paper focuses on the interpretation of markedness in language use following the three perspectives, i.e. pragmatic interpretation, psychological interpretation and cognitive interpretation, with an aim to define the function of markedness.  相似文献

Language is a means of verbal communication. People use language to communicate with each other. In the society, no two speakers are exactly alike in the way of speaking. Some differences are due to age, gender, statue and personality. Above all, gender is one of the obvious reasons. The writer of this paper tries to describe the features of women's language from these perspectives: pronunciation, intonation, diction, subjects, grammar and discourse. From the discussion of the features of women's language, more attention should be paid to language use in social context. What's more, the linguistic phenomena in a speaking community can be understood more thoroughly.  相似文献

理论推导与室内实验相结合,建立了低渗透非均质砂岩油藏启动压力梯度确定方法。首先借助油藏流场与电场相似的原理,推导了非均质砂岩油藏启动压力梯度计算公式。其次基于稳定流实验方法,建立了非均质砂岩油藏启动压力梯度测试方法。结果表明:低渗透非均质砂岩油藏的启动压力梯度确定遵循两个等效原则。平面非均质油藏的启动压力梯度等于各级渗透率段的启动压力梯度关于长度的加权平均;纵向非均质油藏的启动压力梯度等于各渗透率层的启动压力梯度关于渗透率与渗流面积乘积的加权平均。研究成果可用于有效指导低渗透非均质砂岩油藏的合理井距确定,促进该类油藏的高效开发。  相似文献

As an American modern novelist who were famous in the literary world, Hemingway was not a person who always followed the trend but a sharp observer. At the same time, he was a tragedy maestro, he paid great attention on existence, fate and end-result. The dramatis personae's tragedy of his works was an extreme limit by all means tragedy on the meaning of fearless challenge that failed. The beauty of tragedy was not produced on the destruction of life, but now this kind of value was in the impact activity. They performed for the reader about the tragedy on challenging for the limit and the death.  相似文献

In the 19th century the society was controlled by men, and women were just appendants of them, they had not any rights and freedom. But Jane was an exception, she showed some characteristics of early feminist. Jane showed her characteristics of feminism in three aspects: rebellion, equality, and independence. These characteristics were helpful to her success, and feminism is the only way out for women of that time.  相似文献

正The periodicity of the elements and the non-reactivity of the inner-shell electrons are two related principles of chemistry,rooted in the atomic shell structure.Within compounds,Group I elements,for example,invariably assume the+1 oxidation state,and their chemical properties differ completely from those of the p-block elements.These general rules govern our understanding of chemical structures and reactions.Using first principles calcula-  相似文献

We have developed an adiabatic connection to formulate the ground-state exchange-correlation energy in terms of pairing matrix linear fluctuations.This formulation of the exchange-correlation energy opens a new channel for density functional approximations based on the many-body perturbation theory.We illustrate the potential of such approaches with an approximation based on the particle-particle Random Phase Approximation(pp-RPA).This re-  相似文献

正The electronic and nuclear(structural/vibrational)response of 1D-3D nanoscale systems to electric fields gives rise to a host of optical,mechanical,spectral,etc.properties that are of high theoretical and applied interest.Due to the computational difficulty of treating such large systems it is convenient to model them as infinite and periodic(at least,in first approximation).The fundamental theoretical/computational problem in doing so is that  相似文献

For molecular systems,the quantum-mechanical treatment of their responses to static electromagnetic fields usually employs a scalar-potential treatment of the electric field and a vector-potential treatment of the magnetic field.Although the potential for each field separately is associated with the choice of an(unphysical)origin,the precise choice of the origin for the electrostatic field has little consequences for the results.This is different for the  相似文献

Franck-Condon factors bridge the gap between theoretical modeling and experimental observations for molecular electronic spectroscopy and electron transfer.Under the displaced harmonic oscillator approximation,multidimensional Franck-Condon factors are decomposed into a product of many one-dimensional(1D)Franck-Condon(FC)factors,and each 1D-FC factor is associated with one Huang-Rhys factor that determines the leading contribution of  相似文献
