primary variable meaning in English
基本变数
主要变量
Examples
- Water vapour and clouds are the primary variables modulating direct solar absorption .
水汽和云是调节直接太阳吸收的主要要素。 - Time alignment matching between the primary variables and the process variables is an important part of the soft sensor technology
主导变量与过程变量之间的时序匹配是软测量技术不可缺少的组成部分。 - When prediction with little training sample set and large variable si ? is concerned , this paper abstracts the prime factors from the training sample set , then only inputs the prime factors into ann instead of primary variables
对于多指标小样本预测问题，文中利用主成分分析法对原有指标体系进行处理，提取主成分构成新的指标作为神经网络的输入。 - Based on neural network theory , it takes pressure of upper cavity as secondary variable and punching power as primary variable to build model of soft sensing . thus punching power can be predicted using system pressure because of their functional relation . this type of measurement technology provides a new method to parameters measurement which is n ' t easy to got directly
以液压缸上腔压力为辅助变量，桩锤下打力为主导变量，利用函数型神经网络理论建立了两者之间的软测量模型，找到了液压系统油液压力和桩锤下打力之间的函数关系，从而为获取不易直接测量参数提供一种新方法。 - The paper analyzes the non - lineal relations of the quantity of heat exchange and water flux of coil exchanger in part - load operating condition , the shortage of deciding the water flux in bypass pipe , the disadvantage that the operating condition of pumps and chiller ca n ' t be met with the load change of the air conditioning system in different operating condition of using pressure - difference bypassing control in primary water pump system . using load control method in the change of the operating condition of primary water pump system can realize that the load change is small and reasonable in the on / off condition of pumps and m m chiller by comparing load control method in primary variable - flow water pump system with pressure - difference bypassing control method , back water temperature control method
本论文从目前空调工程中使用的变流量水系统入手，研究了盘管换热器在部分负荷下水流量与换热量的非线性关系，分析了文献中介绍的旁通管通流能力选择的不足之处和一次泵水系统采用压差旁通控制时，工况转换不能满足系统控制要求的缺陷；比较了一次泵变流量水系统中压差旁通控制法、回水温度控制法、负荷控制法的精确性，并得出了在一次泵水系统的工况转换时，采用负荷控制法能使冷水机组及其相应水泵在启停时的负荷变化范围较小，更符合建筑物的冷量需求，节能效果较好的结论。
