查询词典 peak factor

On this paper, the pulse electrochemical compound finishing technology parameters which influence the finishing surface roughness was paid attention to, such parameters include the pulse frequency, the duty factor, the peak voltage, the finishing time and so on. Then basic craft rule of two kinds of mold material in finishing process were obtained, and each kind of parameter in this craft was optimized by means of the orthogonal experiments.

在此基础上，重点考察了脉冲电化学复合光整加工过程中各工艺参数对光整后表面粗糙度的影响，如：脉冲频率、占空比、峰值电压、光整时间等，由此获得了这两种模具材料在整个过程中的基本工艺规律，并通过正交试验对光整加工中的各参数进行优化。

Whether sufficient wholesale power can flow between systems to preempt the need to burn gas during the winter electric peak will be a crucial factor that gas system planners watch closely as they make their compression investment decisions.

是否有足够的批发能力可以在体系之间流通调配以预备冬季发电高峰时燃烧瓦斯需求将是至关重要的因素，这使得瓦斯系统规划者们密切地关注着以便决定燃气系统压缩量。

Our study rules out the effect of strain and composition alloying as the main factor of peak splitting. We attributed it to the existence of large amount of non-stoichiometry part in GaN/Si grown by MBE. A direct proof has been observed by HRTEM, which shows that the propagation of dislocations in the underlying layers could be blocked by using periodic AlN/GaN structure.

用三轴晶高分辨X射线衍射研究了Si(111)上生长的GaN中的应变组分问题，我们发现GaN的对称（0002）及非对称（10-12）峰在三轴晶配置下的ω-2θ扫描曲线都会发生劈裂，我们排除了应力和合金化的因素，认为在MBE方法生长的Si（111）上GaN外延层中存在一个占较大比例的稍微偏离化学配比的部分。

This thesis presents the preliminary study of the influence of sentence stress on prosodic features in Mandarin, and of the relationship between duration and pitch under different sentence stress levels. The results show that: The pitch is the most important factor which carries the sentence stress, with the increase of the sentence stress level, the peak of distribution contour of pitch moves towards high frequency area. In the case of"Stress"and"Light", two peaks are found in the distribution contour of duration, which means that the duration of some words are affected by sentence stress, but of others are not. The relationship between pitch and duration in"Normal","Stress"and"Light" are un-correlated, positive correlation and negative correlation respectively.

研究了汉语语句重音对音长和音高的影响、及音长和音高之间的相互关系，结果指出：（1）音高是汉语语句重音的基本表达手段，随着语句重音级别的提高，音高的统计分布曲线向高频方向推移；（2）在连续语流中的词被&重读&和&轻读&的情况下，音长分布出现双峰，表示它们的音长存在着受语句重音的影响和不受语句重音的影响两种情况；（3）词在&正常&、&重读&和&轻读&三种情况下，音高和音长的相互关系分别是：不相关、负相关和正相关。

The experiment show that the vascular endothelial cell growth factor R-2 expression where the low level laser irradiation, regardless of comparison in the pressure zone or the tension area, appears earlier, have higher peak power and longer time than it does in side irradiating.

停止照射后，照射侧血管内皮细胞生长因子受体-2的表达水平仍高于对照侧，提示停止弱激光照射后这种生物刺激作用仍能持续。

Fuzzy logic; trip demand; peak-hour trip factor; the saturation of road network

模糊逻辑；出行需求；高峰小时出行系数；路网饱和度

According to trip-demand time and space distribution characteristics of urban citizens, the peak-hour trip factor and saturation of road network were chosen as the evaluation indexes, meanwhile the index calculation formulas were given; then on the basis of fuzzy logic theory and index characteristics, the membership functions were established by using fuzzy logic toolbox of MATLAB, and the evaluation results of two indexes were analyzed; Finally, the evaluation process was illustrated by a case study of Yangzhou and the results indicated the validity and practicability of the method presented in this paper.

根据城市居民出行需求的时间分布特性和空间分布特性，选用高峰小时出行系数和高峰小时路网饱和度作为评价指标，同时给出指标计算公式；进而以模糊逻辑理论和指标特性为基础，利用MATLAB中的模糊逻辑工具箱得到隶属度函数图形，并对指标值的评价结果进行了分析；最后，用本文提出的方法对扬州居民出行需求合理性进行评价，表明了该方法的有效性和实用性。
