稳定值 meaning in Chinese
stable value
steady value
steady-state value
Examples
- All above six parameters are varied and the results show that the temperature rises to a certain value , which varies with the above factors , however , the time history to obtain the stable value is not affected so much
胎面摩擦温度稳定值的大小因上述参数的变化而变化,但获得稳定值的时间历程受参数变化的影响很小。 - The boundaries had sufficient capacity to offer and hold the vehicles that moved in or out . the density of vehicles would tend to a certain stable value with the acceleration of time step , which could reflect that the urban traffic had appropriate capacity
周边有充分能力提供和接纳出、入车辆,车辆密度将会随着时间步的增多趋向某稳定值,以反映城市的交通存在某适宜的容量。 - In this method , ga is used to optimize connection weights of forward - back neural network until the learning error has tended to stability , then we use sp algorithm with optimized weights to finish short - term load forecasting process
我们用遗传算法来训练网络参数,直到误差趋于一稳定值,然后用优化的权值进行bp算法,实现短期负荷预测,仿真实验结果表明该方法加快网络学习速度,并能提高负荷预测精度。 - This paper analyzes the factors affecting the controlling precision of sand compactibility system and sets up the dynamic model of regression coefficient between sand compactibility and water content . to prevent the insufficiency or excess of sand water content , the amount of the first addition is set as 80 % of the total water addition amount . after the first water addition , we adopt ar model to predict the stable value of sand compactibility to shorten the time mixing the sand . each time we add water , the correction coefficient is introduced to adapt to the change in the composition of sand . the experiment shows that the mathematics model not only makes the water content in sand reach the best range within shorter time , but also directs how the sand composition should be adjusted , which can better conform to the actual situation
分析了影响型砂紧实率控制精度的因素,建立了型砂紧实率-水分回归系数的动态模型.为防止型砂水分不足或过量,将第一次加水量设定为总加水量的80 .第一次加水后,对型砂紧实率稳定值采用ar模型进行预测,以缩短型砂混制时间.每次加水后,引入修正系数,以适应型砂组成的变化.实验表明,该数学模型不仅使型砂水分含量在较短时间内达到最佳范围,同时可指示对型砂组成进行调整,能较好地符合实际情况 - We study the time evolution law of the atomic response in an open - type inversionless lasing system when the probe or driving field is off - resonance , and compare the law with that obtained when the probe and driving fields are resonant . we find that the detuning has considerable effects on the time evolution law : when the probe or driving fields is off - resonance , the dispersive responses for the probe and driving fields are no longer 0 and the two - photon coherence is no longer a pure real ; the variation of the probe detuning can make the time evolution law of the population distributions and the gain ( absorbtion ) of the driving field changing obviously ; with detuning increasing , the time evolution behavior of the gain ( absorbtion ) , dispersion of the probe field and the two - photon coherence will gradually diviate from the evolution law of the standard damped oscillator ; with the driving detuning increasing , the oscillating time of the dispersion of the driving field becomes longer , the amplitude and the stationary value increase
研究了探测场或驱动场失谐情况下开放的型无粒子数反转激光系统中原子响应的时间演化规律,并与探测场和驱动场都共振时的演化规律进行了比较.我们发现失谐对时间演化规律有显著的影响;当驱动场或探测场失谐时,原子对探测场和驱动场色散的响应不再为零,双光子相干不再是纯实量;探测场失谐的变化将使粒子布居和驱动场增益(吸收)的时间演化规律明显改变;随着失谐的增大,探测场增益(吸收) 、色散和双光子相干随时间的演化行为逐渐偏离标准阻尼振子的演化规律;驱动场色散驱动场失谐量的增加而振荡时间变长,振幅和稳定值变大
