这段程序与之前的程序相比，只有一个小错误。在定时器中断服务程序中，我们将`if(Count == 0)`修改为了`if(Count == 60)`，这样在计数器减到0时不会将计数器重新设置为60，而是一直保持在0。因此，需要将`if(Count == 60)`修改回`if(Count == 0)`。修改后的程序如下：

#include <reg51.h>

unsigned char code table[]={0xFC,0x60,0xDA,0xF2,0x66,0xB6,0xBE,0xE0,0xFE,0xF6,0xEE,0x3E,0x9C,0x7A,0x9E,0x8E};
unsigned char Count,i,j;

void Timer0_Init()
{
    TMOD |= 0x01;
    TH0 = 0x3C;
    TL0 = 0xAF;
    EA = 1;
    ET0 = 1;
    TR0 = 1;
}

void Timer0_ISR() interrupt 1
{
    TH0 = 0x3C;
    TL0 = 0xAF;
    Count--;
    if(Count == 0)
    {
        Count = 60;
    }
    i = table[Count / 10];
    j = table[Count % 10];
    SBUF = i;
    while(TI == 0);
    TI = 0;
    SBUF = j;
    while(TI == 0);
    TI = 0;
}

void main(void)
{
    Count = 60;
    Timer0_Init();
    while(1);
}

在程序中，我们还是使用了定时器0来实现每隔1秒钟计数器减1的功能。程序中的`Timer0_Init()`函数用于初始化定时器0，`Timer0_ISR()`函数为定时器0的中断服务程序。在程序的`main()`函数中，我们调用了`Timer0_Init()`函数进行定时器0的初始化，并在无限循环中等待定时器0中断的触发。
