Based on the reanalysis of JEDAC datasets and the assimilation of SODA, the authors studied the variation of the heat status in the West Pacific Warm pool and discussed the ocean temperature variety in the heat content at different depths, the inherent relations between ocean temperatures at surface and subsurface, the eastward propagation of anomalous ocean temperature and the thermocline variation, and the influence of equatorial undercurrent on the eastward propagation.

中文摘要:应用 JEDAC 海温和SODA 再分析资料,分析研究了西太平洋暖池的热状况变化特征,探讨了WPWP 的热含量变化与不同深度海温变化,特别是与表层和次表层海温场之间的内在联系,分析研究了WPWP 异常海温东传过程中与温跃层变化之间的关系,最后讨论了赤道潜流在异常海温东传过程的作用。

It is found that:(1) the variation of dFM may lead to two different features for the IEC,one is the oscillatory behavior of IEC with the spacer thickness,the other is the exponential behavior in the most spacer thickness.(2)As a oscillatory function of dFM ,the IEC exhibits multiple periods and a negative non-oscillatory term.(3)The Fermi energy of the conduction electrons has a little variation as the magnetization of the two FMs changes from parallel to antiparallel alignment,furthermore,this variation is correlated with the IEC to some extent.

结果发现:(1)dFM的变化会导致层间交换耦合出现两种不同的特征,一种是随着中间层厚度的增加,IEC有振荡行为;另一种是其指数衰减行为;(2)作为dFM的振荡函数,IEC表现出多个周期和一个负的非振荡项;(3)传导电子的费密能会随着两铁磁体的磁化排列变化而稍有变化,进一步地,这种变化与IEC有着某种程度的关联。

The reaction mechanism between nickel ion and butynediols in the electroless plating process was analyzed. The results show that the change of BOZ concentration is a quasi first-order reaction, the change of the nickel ion concentration is related to the BOZ density, and this change belongs to a higher order reaction. The reaction rate equation was determined as dC/dt=-8.585×10^(-4)+1.188×10^(-4)t-4.64×10^(-6)t^2+5.8×10^(-8)t^3-2.3×10^(-11)t^4. The activation energy of this process decreases as temperature increases, and it decreases with the BOZ concentration as 64-423 mg/L, it increases with the BOZ concentration as 123~240 mg/L. The S value is positively correlated to temperature, when the temperature is 80℃, the reaction rate and S value are the largest; while when the temperature is above 80℃ and BOZ concentration is over 160 mg/L, S value and the reaction rate decrease gradually.

结果表明,镀液中BOZ浓度的变化是准一级反应,镍离子的浓度变化与BOZ的浓度有关,属多级反应,其反应速率方程为dC/dt=-8.585×10^(-4)+1.188×10^(-4)t-4.64×10^(-6)t^2+5.8×10^(-8)t^3-2.3×10^(-11)t^4,反应体系的活化能E随温度的升高而减少,随BOZ浓度的变化变化:当BOZ浓度在64~123mg/L时,E线性减少;在123~240mg/L时E线性增加。S随温度的升高而增加,当温度达到80℃时S值最大,反应速度最大;当温度超过80℃,BOZ浓度大于160mg/L时,蝎的值逐渐减少,反应速度降低。

In the light of the paleoenvironmental significance reflected by the radiolaria, graptolite, brachiopod,sponge spicule and the rock character, its suggested that the greyish green mudstone at the basal WufengFormation of the Goujiaya section would be probably deposited in 60 to 100 meters deep water, theGuanyinqiao bed in 50 to 80 meters deep, and the radiolaria-bearing silicalite from Wufeng Formation inwater with 200 to 400 meters deep. Combining the above-mentioned water depth with the sea-level changecycles, the change range of every one of the 5 cycles could be further conjectured. They were in ascendingorder: 20~120 m, 80~130 m, about 150 m, 50~250 m, and in excess of 200 m.

Time series simulations are consistent with sediment records from lake bottom cores back to 100 years ago, and spatial distribution modeling of nutrient resources are agreement with changes in the geographical features. The work suggests that the simulations can catch basic characters of the basin nutrient changes, and provides a powerful tool to evaluate nutrient resources, sedimentations and distributions responding to historical changes in catchment environments.
