This was attributable to a combination of factors including the pick - up in domestic demand , the gradual firming in import prices - particularly oil prices - and the dissipation of the lagged effect of the rental decline 8 % 。出现上述情况，是因为本地需求上升、进口价格逐步回稳（特别是油价） ，以及租金下调的滞后影响消失。
The author concludes that the natural resources market web cycle , “ prisoner dilemma ” in pollution game , asymmetry between economic scarcity and ecological scarcity , and the time lag effect of externality are the deep reasons of the natural resource market failure 提出自然资源市场的蛛网周期、污染博弈的囚徒困境、经济稀缺与生态稀缺的不对称以及外部性的时滞效应是自然资源市场失灵的深层原因。
It is concluded that the chinese residents ' saving behavior is different in various stages , the saving irregularity deepens as economy grows and the influential factors besides income have lagged effect of one or two years 本文研究表明，我国居民的储蓄行为在不同的历史阶段有明显的区别，随著社会经济的发展储蓄行为的无规律性会越来越严重，收入以外的其他影响储蓄的因素主要存在一年和二年的滞后作用。
Furthermore , combining with the experiment of yibin zhongba jinshajiang cable - stayed bridge concrete model , this thesis using finite element method studies shear lag effect of the cable - stayed bridge with n cross section and offers suggestion to the project 此外，本文结合宜宾中坝金沙江斜拉桥模型实验，利用有限元程序和模型实验方法，研究双主肋形截面斜拉桥的剪力滞效应，对双主肋截面斜拉桥的设计和施工提供一定的参考。
In a short time , it is not very obvious that the vegetation grows with the temperature relation ; the precipitation and vegetation of salt pond district grow and present obvious positive correlation , it is a main restriction factor of growth of vegetation ; the lagging effect exists in the impact on vegetation of change of precipitation , mainly reflect it on the amount of degree , vegetation height and living beings covered of the vegetation 结果表明：在大时间尺度上，气温与植被生长呈负相关；在短期内，植被生长与气温关系不很明显；降水与盐池地区植被生长呈现明显的正相关，是植被生长的主要限制因子；降水的变化对植被的影响存在滞后效应，主要体现在植被盖度、植被高度和生物量上。
The plexiglass model test is carried out by two selective shape , the stress of each test operating loads was obtained in order to validate the correctness of the finite element modeling . in this paper , a regularity of shear lag effect of main sections in two kinds of box girder is given . as the foresight project of double - level - driveway continuous box girder , this research fully utilizes the space of box girder structure and flexural and torsional properties of high - depth box girder , which have innovative significance and applied foregroundin engineering 对所选择的结构形式进行缩尺有机玻璃模型试验，得到实腹连续箱梁和空腹箱梁在各种试验工况荷载下的应力，通过换算分析，验证了本文所建立的有限元模型的准确性，由此得到两种箱梁各主要断面剪力滞效应的变化规律。
However , the arisen time of overcompensation was different under different stresses , and it appeared at initial - middle stage under the stresses of nutrients limitation and light limitation , while at middle - later stage under the stress of salinity for the cause of the lag effect of osmosis regulation . in addition , the overcompensation in microalgae was probably one internal cause of algae bloom 另外，营养限制胁迫和光限制胁迫下产生的超补偿作用主要是表现在培养过程的初中期，而对于盐胁迫下产生的超补偿作用，由于渗透调节过程的“滞后效应” ，因而其在培养过程的中后期表现得更明显。
Modeling the general solid web continuous box girder and opening - in - web ( open web ) continuous box girder by ansys finite element modeling tool , node stress of governing section and corresponding shear lag values are analyzed . the solution is validated by comparing with variational results and modeling test values . based on the model , the section shear lag induced by dead load , prestress tendons and car loads under the most unfavorable condition and lateral symmetry are also approached . the influence of shear lag effect in double - level continuous box girder is considered with opening - in - web and the web location . the analysis indicates that double - level - load arouses less shear lag effect than one - level - load . when self - weight and prestressed tendons act on together , the shear lag effect on box girder take on a evidently change 基于所建立的有限元模型，本文分别对实腹和腹板开孔两种箱梁在恒载、车载、预应力荷载作用时，各主要截面的剪力滞效应进行分析，通过施加纵向最不利的和横向对称的车辆荷载，研究实腹连续箱梁和空腹连续箱梁在承受双层荷载和单层荷载时引起的剪力滞效应，并考虑腹板开孔及开孔位置对于连续箱梁剪力滞效应的影响。分析表明，双层车载对于箱梁引起的剪力滞系数比单层车载的影响要小，对于箱梁中存在引起的剪力滞后现象有一定的改善作用。
The paper analyzes the existing structural imbalance of institutional factors , such as economy system , economic development level , fir , property rights system , market system between financial innovation countries and china , finding structure of heterogeneous financial market and discrepancy of derivatives proportion would block diffusion of financial innovation , which may be the main cause of time lag effect in adoption of financial innovation diffusion in china 本文通过分析我国与金融创新国在金融体系、经济体制、经济发展水平、金融相关率、产权制度、市场结构等因素上存在的结构性不均衡，发现异质性金融市场间的结构和金融工具比例的差异性对金融创新扩散可能产生的阻碍机制也是引发我国采纳金融创新扩散中出现时滞现象的重要原因。
The project is completed in the collaboration of the transportation college of jilin university and transportation science institute in jilin province . the paper mainly studies the characteristics and mechanical performance of small size member of bridge , the problems of concrete dense degree and shear lag effect of wide flange . the static load test and supersonic nondestructive test of four pieces of prestressed i - girder with varying section are carried out in bridge structure laboratory of jilin university 本文针对桥梁构件局部尺寸较小部位的混凝土密实度问题,进行了2片腹板宽度为14cm , 2片腹板宽度为16cm的变截面预应力工字梁的静载试验和超声无损检测试验,提出密实度系数的概念,对试验梁的密实度进行定量评定,推导了工字梁的塑性系数公式,基于塑性理论给出了试验梁的开裂荷载和极限承载能力计算公式,分析了试验梁的密实度对其开裂荷载和极限承载能力的影响。
