1. In this paper , i consider the traveling wave solutions and peakons of the generalized camassa - holm ( gch ) equation and give the express of the solitons of this equation . the peakons and their figures of the gch equation are given with the mathematic software for m - 1 , m = 2 and m = 3 in particular ; for m = 3 , i get the generalized dissipative camassa - holm equations by adding a dissipative term and find two types exact traveling wave solutions of this equations . i also apply the homogeneous balance method into the gch equation so that i get a group of smooth solutions for m = 2 and m = 3 and the backlund transformation for m - 3 of the gch equation
   本文研究廣義camassa - holm ( gch )方程的行波孤立子解及尖峰孤立子解，給出gch方程的行波孤立子解的表達(dá)式，特別的，對m = 1 、 m = 2 、 m = 3時(shí)利用mathematica數(shù)學(xué)軟件進(jìn)行計(jì)算，解出了gch方程的尖峰孤立子解，并給出了此時(shí)gch方程的尖峰孤立子解的圖形，使數(shù)值分析和理論相結(jié)合；對m = 3時(shí)的gch方程增加一耗散項(xiàng)u _ ( xx )后得到廣義耗散camassa - holm方程，并解出此方程的兩類精確行波解；本文將齊次平衡法應(yīng)用到gch方程中，解出m = 2 、 m = 3時(shí)的gch方程的一組光滑解，同時(shí)應(yīng)用此方法得到了m = 3時(shí)的gch方程的backlund變換。
2. It's difficult to find gch in a sentence. 用gch造句挺難的
