查询词典 fall of tide

The temporal change in floes size of fine suspended sediments was measured in Xuliujin of the Changjiang Estuary in June of 2003, by using an in situ laser diffraction particle sizer, the laser in situ scattering and transmissomerty-100(LISST-100). The spectrum analysis was applied to analyze the fluctuation of floes diameter during the spring tide and the neap tide.

2003年6月利用现场激光粒度仪(LISST-100)在不扰动的情况下，获取了长江口徐六泾处悬浮细颗粒泥沙絮凝体的现场粒径系列资料，应用谱分析方法研究了絮凝体粒径在大小潮、表底层的变化规律。

The observation showes that average VC, D,Δp and ω at the surface water during spring tide are 98.0μl/L, 39.8μm, 1173 kg/m^3 and 1.14 mm/s, whereas those during neap tide are 70.8 μl/L, 64.4μm, 919 kg/m^3 and 2.32 mm/s, respectively.

观测结果显示，徐六泾大、小潮表层絮凝体体积浓度、粒径、有效密度和静水沉速的平均值分别为98.0μl/L、39.8μm、1173kg/平方公尺、1.14mm/s和70.8μl/L、64.4μm、919kg/平方公尺，2.32mm/s。

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。

In the astronomy aspect, in 1672 Newton has formulated the reflecting telescope; He also explained not only the tide phenomenon, points out the tide the size the same lunar month related, moreover also has the relations with sun's attraction; Moreover, Newton extrapolated theoretically Earth is not a spheroid, but is the two-pole is slightly flat, the equator slightly drum, and explained the year old bad phenomenon from this and so on.

在天文学方面，1672年牛顿创制了反射望远镜；他还解释了潮汐的现象，指出潮汐的大小不但同朔望月有关，而且与太阳的引力也有关系；另外，牛顿从理论上推测出地球不是球体，而是两极稍扁、赤道略鼓，并由此说明了岁差现象等。

And after the nadir of the winter solstice the new sun secretly climbs towards the eastern horizon while the tide ebbs further and further out to final emptiness, whereupon Sol's nascent progression is suddenly announced at the vernal equinox, when he appears so resplendently above the distant waves and enters the upper vessel of day, which heralds the turn of tide, the reversal of regression to forward flow.

在冬至点之后，新日隐秘的上升至东方的地平线，潮汐一步步降落至最低处，直至初生的太阳最终到达春分点，在遥远的浪潮之上开始闪耀，进入一日的上半部分。这也预示了潮汐重新上涨，与之前的退潮相反开始顺流上涨活动。

The results show that the tidal property in Dongshan Bay belongs to regular semidiurnal tide. The action of tide current is strong and the flow velocity is currently more than 100cm/s in the bay mouth area and the channel.

结果表明，东山湾主要属于往复式的规则半日潮流，潮流作用较强，其口门处和湾内水道上的实测最大流速一般大于100cm/s。

In searched place, semidiurnal tide is in the highest flight absolutely, so their swing direction of change can represent the swing change rule of Zhejiang tide.

分析发现：由于研究海区内，半日分潮占绝对主导地位，故其振幅值走势基本可代表浙江潮波的振幅变化规律。

It can be concluded that the periodic variation of tidal range and water level has both typical semidiurnal and diurnal and semi-monthly period of tide, and 64.8 d period of river runoff, which indicates that water level of the Zhujiang Delta is controlled by tide and river flow.

不同河段潮差及各分潮波振幅与径流量的大小具有明显的反相关关系，径流量越大，潮差越小，三水站潮差随流量以-0 0002的速度减小，网河区下游河段则减小得较慢。上游径流量越大，因克服径流的阻碍作用而消耗的能量越大，潮汐作用强度迅速减弱，各分潮潮波振幅和潮差沿程减小越快。

Glass eels use the behavioral pattern of semidiurnal vertical migration called selective tidal stream transport, and a greater number of glass eels were caught during flood tide than that during ebb tide.

长江口是日本鳗鲡鳗苗的主要产区，利用2007年1-5月在长江口的长兴岛、横沙和杭州湾小洋山4个取样点得到的日本鳗鲡鳗苗渔获量数据，初步研究了鳗苗的补充时间分布以及补充量与潮汐、月相等环境因素之间的关系。

Slack water usually happens near high tide and low tide.

在高潮和低潮之间通常有水的滞留。

As of Tuesday, Google's results were still censored in China.

截至周二，谷歌的搜索结果仍受中国审查。

In order to make the positive action increase and negative one decrease, the sub-forces of the social factors must be adjusted to form a centripetal force.

在这一过程中，人的主体性发挥是社会有机体健康发展的灵魂。
