查询词典 variation range

The organic matter and total N"s variation of the upper and below layer were identical whose range remained constant in each season; the soil NlV-N content in the upper layer was higher than hi the below in Spring and Autumn, but this change was complicated hi Summer and Winter owing to different forest measures; the peaks and valleys of NCV-N hi the upper and below soil layer appeared in the same tune, but the change showed no laws in different forest lands; the variation of the available N was approximate to NHU+-N; the range of each layer"s change of the hydrolysable N was identical that appearedparallel lines in figure.

COV gathers can also be constructed through selecting traces from different cross spreads of a 3D survey. A simple and practical way of constructing COV gathers can he described as that 1 when a dominant receiver line direction is determined, the inline offset and crossline offset of every trace can be calculated; 2 the inline offset and crossline offset ranges fruit; negative to positive for the whole dataset can be well represented by the range of the receiver spread of a typical source; 3 the full range of inline offsets can be divided into several sob ranges using twice the source line spacing and the full range of crossline offsets can be divided using twice the receiver line spacing; and 4 one sod; sob-range inline offset and one such sob-range crossline offsets form a COV gather.

一个简便实用的构造COV道集的方法是：在给定检波线的走向后，计算出每一地震道的inline炮检距和crossline炮检距；用观测系统中一个具有代表性的炮点的检波器排列范围来确定整个数据的inline炮检距范围和crossline炮检距范围，用两倍的炮线间距把inline炮检距的范围分成若干份，用两倍的检波线间距将crossline炮检距的范围也分成若干份，一份inline炮检距和一份crossline炮检距就构成一个炮检距向量道集。

After that, a numerical model about Zhejiang shore tide is established by mike21 program. After validating the good agreement between simulated results and observed ones, the planar hydrodynamic flow of this ocean area is analysed in detail. Then co-tidal and co-range chart of each main tide is drew based on the computational result. It can be found that each co-tidal and co-range chart that is based on the simulated result is suitable to the co-tidal and co-range chart that is deduced from autoptical data, besides, the modle co-tidal and co-range chart can perfect the co-tidal and co-range chart from autoptical data where autoptical data is too hard to get .

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.
