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。

To place a point at the x-coordinate of the right end of a line and the y-coordinate of the left end of a line.

在线的右端点的x坐标和线的左端点的y坐标放置一个点。

Whether on this account, or from absentmindedness, or from sleepiness, she did not perceive that they had long ago passed the point at which the lane to Trantridge branched from the highway, and that her conductor had not taken the Trantridge track.

她没有出声，座下的马已经缓缓地向前走了很长一段路了，走到后来，一片薄薄的发亮的雾，本来整个晚上都弥漫在山谷里，现在已经散布开来，把他们包围了。

Melt enough Greenland ice, and you reach the point at which you're not simply dripping meltwater into the sea but dumping whole glaciers.

"Autumnal equinox:The point at which the ecliptic intersect s the celestial equator, the sun having a southerly motion."

秋分：指黄道与天赤道相交的一点，自此太阳向南运动。

"Autumnal equinox:The point at which the ecliptic intersects the celestial equator, the sun having a southerly motion."

秋分：指黄道与天赤道相交的一点，自此太阳向南运动。

The mass of a black hole is confined to an infinitely small point at its centre, called a singularity.

黑洞所有的质量都处于其中心一个无穷的小点上，我们叫它&奇点&。

It is a period where composers still working in the Baroque style were still successful, if sometimes thought of as being more of the past than the present-Bach, Handel and Telemann all composed well beyond the point at which the homophonic style is clearly in the ascendant.

虽然有些时候考虑到跟与当前相比更多的是以前的巴赫、亨德尔和泰勒曼，这些作曲家在和声风格上完全相反的风格更具有明显的优势，但这段时期依然在创作巴洛克风格音乐的作曲家们仍然很成功。

To enter in December, the SSE Composite Index bounced back to the 2100 point at one time.

进入12月，上证综合指数反弹到2100点一次。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。

The relationship between communicative competence and grammar teaching should be that of the ends and the means.

交际能力和语法的关系应该是目标与途径的关系。
