To get rid of the other infinite series, we must set the arbitrary constant that multiplies it equal to zero . 為去掉另一個無窮級數(shù),必須使任意常數(shù)乘之后等于零。
A device whose state represents a number and that , on receipt of an appropriate signal , causes the number represented to be increased by unity or by an arbitrary constant ; the device is usually capable of bringing the number represented to a specified value , for example , zero 一種裝置,其狀態(tài)表示一個數(shù),當接收到一個適當?shù)男盘枙r,所表示的數(shù)加“ 1 ”或一個任意常數(shù);這種裝置通常能夠將所表示的數(shù)變化到一個指定的值,例如0 。
In chapter 2 , the ii ordering is presented and the arbitrary functions and the arbitrary constants are least in the solution of formal series under the ii ordering by illustration ; furthermore , the author introduces the application of the standard form of reid to ascertain the target equation of linear constant partial equations 在第二章中,作者給出了reid標準型算法中的型序關系,通過舉例說明在型序下,得到的形式冪級數(shù)解中任意函數(shù)和任意常數(shù)的個數(shù)最少;并提出了reid標準型的一個重要應用:確定線性常系數(shù)偏微分方程組的目標方程。
