Ecological function potential drops from 54.08% to 37.02% and the basic population capacity increases from 199 400 to 315 100. Emergy self-support ratio drops from 74.58% to 54.13%, while emergy investment ratio increases from 34.0% to 85.0%. Emergy density increases from 1.34×10^11 to 1.97 ×10^11 sejm^(-2) and emergy/money ratio decreases from 4.93×10^14 to 1.81×10^13 sej$^(-1). There is an increase in environment load ratio and net energy yield ratio from 0.85 to 1.70 and from 0.18 to 1.82 respectively.

The thermal gradients of the depression decreased during the Cenozoic time. However, it decreased quickly in Eogene, but only changed a little during the Neogene period The thermal gradient was 540～500℃/km during the period of the Kongdian group deposition, 500～400℃/km during the period of Shahejie group, 400～385℃/km of Dongying group and 385～355℃/km during the Neogene.

研究结果表明，济阳坳陷新生代以来的古地温梯度是逐渐降低的，但在早第三纪时期下降的幅度较大，而在晚第三纪－第四纪则下降的幅度明显较小；济阳坳陷在孔店组沉积时期的地温梯度为540～500℃/km之间，沙河街沉积时期为500～400℃/km，东营组沉积时期为400～385℃/km，晚第三纪时期为385～355℃/km，第四纪以来基本未变。

Igh concentrations of H〓O〓 and MV caused oxidative injury to antenna system, and led to the decline of qNP, especially in chilling-susceptible cultivars.

〓O〓和MV对水稻不同耐冷品种荧光参数的影响不同浓度的H〓O〓和MV处理水稻幼苗，常温下两品种的Fo都下降，qNP增加，但过高浓度会对天线系统造成氧化胁迫，使qNP下降，而且冷敏感品种对活性氧的增加更敏感。H〓O〓和MV处理加剧水稻的低温伤害。

Largely attributable to increased use of the Pap test, cervical cancer death rates declined 74 percent between 1955 and 1992 and continue to decline by nearly 4 percent annually.

主要归功于子宫颈巴氏试验的增加，从1955年到1992年期间宫颈癌的死亡率下降了74%，并将以每年4个百分点继续下降。

In order to disclosure the reason why the electrocatalysis activeness and selectivity droped after being used several hundred hours continuously, the x-ray diffraction, scanning electron microscopy and energy dispersive spectroscope have been used to characterize the surface condition variations of Monel metal. The results indicated: Monel metal belongs to the Cu-Ni alloy around the electrolysis experiment.And after being used for 600hr, the surface layer element composition and geometry distribution of the alloy changed, namely in the alloy the Cu element /which superficial free enthalpy was smaller,"concentrated" to the alloy surface,and formed one kind of marble structure microcrystallite.Thus the electrode surface becamed rough a

为了揭示蒙乃尔合金阴极在连续使用数百个小时后电催化活性剂选择性下降的原因，采用X射线衍射仪、电子扫描电镜和电子能谱分析仪对电解实验所用的蒙乃尔阴极材料在电解实验前后的表面状态进行了表征，结果表明：所使用的蒙乃尔合金阴极材料在电解实验前后均属于Cu-Ni合金，使用600hr后，由于表面层元素组成和几何排布发生了变化，即合金中表面自由焓较小的Cu元素向合金表面&富集&，形成一种大理石结构的微晶，表面粗糙、不均一，这是造成其对硝基苯电还原的催化活性及选择性随着使用时间延长而逐渐下降的主要原因，同时也为此类电极的修饰改进提供了方向。
