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。

It was suggested that aging did not only influence diastolic filling period, but also influence STI. 3. With increasing age, whether at rest or during exercice, fractional shortening of minor semiaxis, mean velocity of circumferential fiber shortening, cardiac index and ejection fraction did not change, but immediately post pacing, PEP prolonged and PEP/ LVET increased in elderly group and did not change in young group. It was suggested that STI was sensitivity in detecting systolic function of LV. 4. There was a good correlation between aging and decreased compliance and diastolic function of left ventricle which was manifested by a reduction of early diastolic peak folw velocity, time-velocity integral of early diastole, 1/3 filling fraction (1/3FF)(r=-0.958,-0.875 and -0.937, P<0.01~0.001) and a significant compansatory increase in peak flow velocity of atrial contraction, time-velocity integral of atrial contraction, the ratio between APFV and EPFV and the ratio of ATVI and Total TVI (r=0.958, 0.956, 0.966 and 0.986, P<0.001) and the prolongation of Dec T and RFP with increasing age. It was particularly true for the subgroups above the age of 50 years.

静息状态下收缩时间间期与年龄无相关性,负荷后即刻,老年组射血前期延长(P<0.05),射血前期与射血期比值加大(P<0.05),青年组无变化,提示年龄因素亦影响STI,但由于静息状态下得到代偿,STI变化往往表现不明显。3、静息及负荷状态左室短轴缩短率、平均周径缩短率、心指数及射血分数均不随年龄增长而变化,而负荷后即刻老年组PEF延长,PEP/LVET加大,提示STI是检测左室收缩功能的敏感指标。4、随年龄增长,心房收缩期充盈峰值流速、流速积分、充盈分数及心房收缩期与舒张早期充盈峰值流速之比值显著增高(r=0.958、0.956、0.986及0.966,P均<0.001),舒张早期充盈峰值流速及流速积分、1/3充盈分数(1/3FF)下降(r=-0.958、-0.875及-0.937,P<0.01~0.001)。

The tidal river discharge observing system of this thesis gives a new method and experience of the hydrology observing to the river reach and cross section with complicated landform and flow, or busy shipping.

When gas superficial velocity was about equal to liquid superficial velocity, the probability density function of liquid holdup had a twin-peaked, when liquid superficial velocity was constant, one of the peaks would fade out and disappear with the in crease of gas superficial velocity. Through using the characteristics, the relative size of gas and liquid superficial velocity can be set initially.

在段塞流动中,当气相折算速度和液相折算速度相差不大时,持液率概率密度函数呈双峰分布;当液相折算速度不变时,随着气相折算速度的增大,持液率概率密度函数第2峰值逐渐减小,直至消失而变为单峰分布;利用这一特征可初步确定段塞流动中气、液相流量相对大小。

Based on natural gas state equation and dynamic theory of natural gas migration, natural gas velocity of flow rate equation before and after temperature and pressure decreasing is fetched, and with which interface natural gas lengths in different reservoirs are calculated and the changing law of equivalent-length natural gas in migration is analyzed, whence it is discovered that migrating velocity of natural gas along tilting up reservoir is increasing inch by inch, along with temperature and pressure continuously decreasing.

由此发现,在运载层物性不变的情况下,天然气沿上倾地层向上倾方向运移的过程,是随地层温度和压力不断降低、其运移速度逐渐增大的过程,如果有后续气体的加入,会使气体长度增大,致使运移速度增加得更快。

The relations of electrophoresis velocity, electroosmosis velocity and electric dispersion velocity are also investigated with these expressions. The results show that this new model offers a better explanation for peak compression effect on the migration behaviour of charged solute in CEC. The retention time will be shorter by peak compression effect, which is similar to a solvent gradients process. The peak compression effect is not steady, and doesn't appear until the conditions are fitted in some special situation.

基于弛豫理论所建立的基本模型,在考虑溶质在两相中皆有可能发生正、反向迁移的情况下,得到了流出曲线一阶原点矩和二阶中心矩的理论表达式,并通过对溶质在两相中电扩散速率与电泳速率、电渗流速率关系的分析结果证实:溶质在固定相表面的电扩散行为可以使其保留变弱,出峰加快;而这种电扩散导致的超常柱效峰的出现具有不稳定性,只有在多方面因素综合影响匹配的情况下才可能出现。

Aiming at these problems, we have designed the processing workflow to effectively suppress the surface Wave interference, regular interference, high energy interference, and other random noise interference.
