We can also see that because damping factor is a ratio that requires the load impedance to compute , it must be stated against some known impedance to be meaningful 我们还可以看到因为阻尼因子是一个比率值,而且需要负载阻抗已知才能够进行计算,所以阻尼因子必须和某一已知的阻抗同时具明才有意义。
However , few people actually understand precisely what the term means , what the consequences of a particular damping factor rating might be for the ultimate desired result ( sound reproduction 然而,只有很少人真正能够理解这个术语的准确含义,了解某一特定的阻尼因子量度如何能对最终声音重放的结果产生影响,或者有那些因素和系统或阻尼因子有关。
The dependences in multitemporal multispectral images by independent component analysis are reduced . in the algorithm , damped factor is imported to reduce the dependence on initial weights , thus the robust of the algorithm is improved 在改进的独立成分学习算法中,通过在梯度下降方法中引入阻尼因子,降低了对初始值的依赖,提高了独立成分求解的稳健性。
It helps when an amplifier has a high damping factor ( in other words , a low output impedance ) because the degree to which it is affected , itself , by these annoying speaker behaviors is reduced along with its output impedance 这个时候如果放大器的阻尼因子足够高的话它就可以帮助我们了(换句话说,低输出阻抗) ,因为阻尼因子的量度直接影响到这个问题,放大器的输出阻抗越小,相应的这些恼人的放大器的行为也会减少。
Taking the contact stress , bend stress stiffness and temperature stress as the condition , taking the weight of the kiln tyre as optimization aim function , the redia and the width of the tyre are optimized general optimize methods just consider the affecting of the parameters to aim function , but in fact , structural parameters ( such as structure dimension , interval and so on ) , physics and dynamics ( damp factor , conduct factor , friction factor material ' s elastic module strength limits and so on ) , which would be changed after used . the difference are called discrepancy robust design ' s basic concept is : all design parameters " discrepancy will affect the aim funct ion and arouse the quality target discrepancy 一般的优化方法,仅仅考虑了参数对其目标函数的影响,而实际情况下有些参数是变化的,产品的结构参数(如几何尺寸、间隙等) 、物理和力学参数如阻尼系数、传导系数、磨擦系数、材料的弹性模量和强度极限等的设计值与制造后和使用中的实际值会有差异,这种差异称为设计变量和噪声因素的变差。
The paper applies sdm in drawing the map of pollution areas . by synthesizing contaminated factor , saturated esdd and damp factor in pollution areas , the equal saturated esdd is presented . the isopleth map for equal saturated esdd is drawn by grid method based on kriging regression , and the isopleth map is regarded as the map of pollution areas 通过将影响污区分布的积污因素、盐密指标、湿润因素这三种因素综合为等效盐密,运用克里金法实现等效盐密的插值,最终通过网格法绘制等值线图实现了电网污区分布图计算机自动绘制。
Establishing an human spine dynamic model is an significan event to study spine injured biomechanics of pilot " s ejective injury , parachute opening , landing and study the endurance to impact loading on human spine . in this paper , the huston " s method of kane " s equations is developed so that it can be applied to the multibodysystem including translation between the bodyies . the dynamic model of human spine is provided basing on these theories , while the big movement of spine is considered . the deformation of vetebra is far smaller comparing with the intervetebra disc , so the spine is considered into multibodysystem including rigid bodies ( vetebra ) and the flexible bodies ( intervetebra disc ) . the computer solution correspond with the results of the large scale human impact test . the rigid coefficient factors and the damping factor of intervetebra joints are obtained 人体脊柱动力学模型的建立对研究飞行员弹射救生、伞兵跳伞开伞、着陆等脊柱损伤的生物力学以及研究人体脊柱耐受冲击载荷的极限问题都具有重要意义.首先发展了凯恩方程的休斯顿方法,使其可应用于变形体连接的多体系统,并以此理论为依据建立人体整椎脊柱冲击动力学模型,此时考虑脊柱的大位移运动,每个椎骨的变形相对椎间盘的变形小得多,把脊柱看成由刚体(椎骨)和变形体(椎间盘)组成的多体系统.并以大型真人坐姿冲击实验结果进行了拟合,最后得到腰椎间关节刚度系数因子和阻尼系数因子
In order to study the main effected factors of the aseismic performance of concrete dampers , experiment of dampers in forms of concrete ductile columns was conducted subjected to low cyclic loading , the damage pattern , hysteresis behavior , ductility factor and equivalent viscous damper factor of the dampers were obtained 摘要为考察混凝土延性柱耗能器抗震性能的主要影响因素,通过对多根延性柱耗能器的低周反复荷载试验,得到其破坏形态、滞回特性、延性系数、等效黏滞阻尼系数等参数。
In an audio system, the damping factor gives the ratio of the rated impedance of the loudspeaker to the source impedance. Only the resistive part of the loudspeaker impedance is used.
