These Thoughts so oppress'd my Mind, that I began to give over my Enterprize, and having haled my Boat into a little Creek on the Shore, I stept out, and sat me down upon a little rising bit of Ground, very pensive and anxious, between Fear and Desire about my Voyage; when as I was musing, I could perceive that the Tide was turn'd, and the Flood come on, upon which my going was for so many Hours impracticable; upon this presently it occurr'd to me, that I should go up to the highest Piece of Ground I could find, and observe, if I could, how the Sets of the Tide, or Currents lay, when the Flood came in, that I might judge whether if I was driven one way out, I might not expect to be driven another way home, with the same Rapidness of the Currents: This Thought was no sooner in my Head, but I cast my Eye upon a little Hill, which sufficiently over-look'd the Sea both ways, and from whence I had a clear view of the Currents, or Sets of the Tide, and which way I was to guide my self in my Return; here I found, that as the Current of the Ebb set out close by the South Point of the Island; so the Current of the Flood set in close by the Shore of the North Side, and that I had nothing to do but to keep to the North of the Island in my Return, and I should do well enough.

我思想压力很大，不得不考虑放弃原定的计划。我把小船拉进沿岸的一条小河里，自己迈步上岸，在一块小小的高地上坐下来沉思。我心情忧郁，心绪不宁。我害怕死，又想前去探个究竟。正当我沉思默想之际，只见潮流起了变化，潮水开始上涨。这样，我一时肯定走不成了。这时，我忽然想到，应该找一个最高的地方，上去观察一下潮水上涨时那两股急流的流向，从中我可以作出判断，万一我被一股急流冲入大海，是否有可能被另一股急流冲回来。我刚想到这一层，就看见附近有一座小山；从山上可以看到左右两边的海面，并对两股急流的流向可以一目了然，从而可以确定我回来时应走哪一个方向。到了山上，我发现那退潮的急流是沿着小岛的南部往外流的，而那涨潮的急流是沿着小岛的北部往里流的。这样，我回来时，小舟只要沿着北部行驶，自然就可以被涨潮的急流带回来。

Results show that floes' VC and D at the surface water were closely related to current velocity; and the peaks of VC lag those of the current velocity. The lag variation during ebb and flood tides is 10-30min and 30-50 min, respectively. Current velocity at 50 cm/s is a turning point of D vs. vertical average current velocity, before the point, Dm increases with current velocity, and decreases after the point. Similarly, VC at 75μl/L becomes a critical point in the surface water, below the point, D increases with VC, and above the point, D stabilizes.Δp is D dependent, larger floes have much lower Δp than smaller floes. Both D and Δp of floes affect ω. In the surface water during spring tide and neap tide, a power exponent relationship exists between Δp and D, and ω and D.

研究表明：①长江口徐六泾表层絮凝体体积浓度主要受水流流速影响，再悬浮现象明显，体积浓度过程线滞后流速过程线，落潮期间滞后10-30min，涨潮则滞后30-50min；②小于一定流速时絮凝体平均粒径随流速增大而增大，大于一定流速时絮凝体平均粒径则随流速增大而减小，徐六泾夫、小潮表层絮凝体在50cm/s的垂线平均流速时出现平均粒径与垂线平均流速关系的转折；③徐六注大、小潮表层絮凝体平均粒径在体积浓度75μl/L时出现平均粒径与体积浓度关系的转折，体积浓度小于75μl/L时粒径随体积浓度增加而增大，超过75μl/L时粒径随体积浓度的增加变化不明显；④絮凝体有效密度由粒径大小控制，粒径大，有效密度小，反之亦然，粒径和有效密度共同决定絮凝体静水沉速，有效密度和沉速与平均粒径之间均存在良好的幂指数关系。

This invention concerns a current control process for a feed-in voltage converter, wherein a detected flux-inducing current component and a detected torque-inducing currrent component of an actual currrent vector of a rotating field machine are each controlled for a flux-inducing current component set value and a torque-inducing current component set value of the rotating field machine. To that effect, a control set-value (DELTA u*sp, DELTA u*sq) is determined, dependent each time upon a determined current component control deviation. From these, current components of an actual current vector are formed each time by overlay of a formed pilot value (u*spvor, u*sqvor). This invention also concerns a device for carrying out this process.
