A high-order accuracy explicit difference scheme for solving 4-dimensional heatconduction equation is constructed.The stability condition is r = △t/△x2 = △t/△y2 = △t/△]z2 = △t/△w2<3/8,and the truncation error is O(△t2 + △x4).

在同事眼中,孙惠民有个“活字典”的称号。因为在工程建设标准定额、工程造价管理方面,他不用去翻阅书本、查阅资料,就能闭着眼睛把各项工程标准、造价规定背得滚瓜烂熟。这个不
