Soil carbon,soil total N,and pH belonged to high and soil total P belonged to medium degree spatial correlation at 60m lag intervals,respectively.However,there were significant differences in ranges of spatial autocorrelation among four soil properties,among which the effective range of soil organic carbon was the highest(261m),followed with soil total N(208m),pH(156m),and soil total P(133m).

在60m步长间隔尺度下，土壤有机碳、全氮和pH有强烈的空间相关性，土壤全磷空间相关性为中等程度。4种土壤养分的空间自相关范围具有明显的差异，有机碳的有效变程最大(为261m)，全氮(208m)和pH(156m)次之，全磷的有效变程最小(133m)。

On average, the SSC in winter is 2 times than that in summer; and the SSC in spring tide is 2.96 times than that in neap tide.(2) The correlation coefficient of the daily tidal range and SSC at a tide circle is 0.86, and it goes up to 0.96 and 0.93 with one day and two days lag of SSC. This reflects that there has a hysteresis of one or two days of SSC to the tidal range.

三年平均而言，冬季悬沙浓度为夏季的2.0倍，大潮悬沙浓度为小潮的2.8倍；(2)平均的大-小潮半月周期变化中日悬沙浓度与同日潮差之间的相关系数为0.86，(显著性水平0.01)，与提前1日潮差之间的相关系数为0.99(显著性水平0.01)，与提前2日潮差之间的相关系数为0.93(显著性水平0.01)，反映潮差变化对悬沙浓度的影响有1-2天的滞后效应；(3)芦潮港月均悬沙浓度与长江大通站的月均流量呈显著负相关，尤以流量滞后19天的相关性最好。

In accordance with these questions, one kind of method solving these issues was put forward in this text, and namely adopting mathematics to build the method of pattern, by w-ay of studying the big needle drum system of PASSIM's cigarette machine, to use the mathematical model of big needle drum system of " black box " method establishment, and uses whole parameter and the correlation coefficient to map out the big needle drum system mathematical model of least square method, the question time lapse that what in accordance with the system exists pure adopts Smith compensator to estimate the compensator in advance solving the issue of system lag, and uses whole fixed method of frequency conversion control engineering and PLC's control engineering and PID etc to put into effect transforming to the system, and finally by way of theory verify and reality to verify to prove the success of system transformation.

针对这些问题，本文提出了一种解决这些问题的办法，即采用数学建模的方法，通过研究PASSIM卷烟机大针鼓系统，利用"黑匣子"方法建立大针鼓系统的数学模型，并运用最小二乘法整定出大针鼓系统数学模型的参数及相关系数，针对系统存在的纯时滞问题，采用史密斯预估计补偿器来解决系统滞后的问题，并利用变频控制技术和PLC控制技术、PID参数整定方法等对系统实施改造，最后通过理论验证和实际验证证明了系统改造的成功。
