A New Evaluation Method of Cyclic Variations;
一种评价循环波动的新方法
The cyclic variations of combustion in a DI diesel engine with different fuel supply advance angles at idle condition are analyzed based on the measured needle valve lift and cylinder pressure.
测量了怠速工况下直喷柴油机在不同供油提前角时的针阀升程及气缸压力,计算分析了各参数循环波动变化情况。
The cyclical movement which has the cycle of 4 years just as long as the cycle of international economy is dug out, and the economic, political, social, science and techn.
以中国出口集装箱运价指数(CCFI)作为中国国际集装箱班轮运输市场运价测度指标,采用时间序列乘法模型对CCFI进行分析,发现CCFI近8年来存在着长期下降的趋势,对集装箱班轮运输市场春夏旺秋冬淡的季节性波动进行验证分析,并发掘出CCFI4年的循环波动周期恰恰与世界经济4年左右的周期相吻合这一规律,最后对将来可能使CCFI发生不规则变动的国际政治、经济和自然灾害等因素进行预测分析。
The engine combustion characteristics,heat release rate and their cycle-to-cycle variations are analyzed,and the cycle-to-cycle variations of combustion and heat release rate in nutural asperated and turbocharged diesel engines are.
