Treat the problem in the x, y, z system . 在X、Y、Z座標(biāo)系中處理問題。 The vector z is known as the state vector of the system . 向量Z稱為系統(tǒng)的狀態(tài)向量。 The coordinates x, y, and z are called the relative coordinates . 坐標(biāo)x,y和z叫做相對(duì)坐標(biāo)。 Subscripts z and e are for zonal and eddy components respectively . 下角標(biāo)Z和E分別表示緯向分量和旋渦分量。 Consider now a structure with corrugations extending from z=o to z=1 . 現(xiàn)在我們考慮刻紋從z 0延伸到Z1的結(jié)構(gòu)。 The choice of orientation of the(x, y, z)coordinate system is, of course, quite arbitrary . 當(dāng)然,坐標(biāo)系(x,y,z )軸向的選擇是任意的。 This diagram immediately suggests defining two quantities which characterize the complex number z . 這個(gè)圖立即指出定義兩個(gè)表征復(fù)數(shù)Z的量。 It is easy to show, for an exponential decay, that the uncertainty in the life time is also z . 很容易證明,對(duì)于指數(shù)衰減來說,壽命的不確定性也是z。 we wish to make triples (x, y, z)from the integers{1, 2, …, (n+1)}. 我們要從整數(shù)集1、2、…(n1)中取三數(shù)組(x,y,z )。 Capital i stands for the number of protons in the nucleus, and small z is the z coordinate of the electron . 大寫I代表核中質(zhì)子數(shù),小寫z是電子的z坐標(biāo)。
