```go
package main

import (
	"fmt"
	"syscall"
	"unsafe"
)

// 记录系统信息
type MEMORYSTATUSEX struct {
	dwLength                uint32
	dwMemoryLoad            uint32
	ullTotalPhys            uint64 // 物理内存总量
	ullAvailPhys            uint64 // 可用物理内存
	ullTotalPageFile        uint64
	ullAvailPageFile        uint64
	ullTotalVirtual         uint64 // 虚拟内存总量
	ullAvailVirtual         uint64 // 可用的虚拟内存量
	ullAvailExtendedVirtual uint64
}

func main() {
	memoryStatus := new(MEMORYSTATUSEX)
	memoryStatus.dwLength = uint32(unsafe.Sizeof(*memoryStatus))

	// 调用GlobalMemoryStatusEx得到系统内存信息
	GlobalMemoryStatusEx := syscall.NewLazyDLL("kernel32.dll").NewProc("GlobalMemoryStatusEx")
	GlobalMemoryStatusEx.Call(uintptr(unsafe.Pointer(memoryStatus)))

	fmt.Printf("物理内存总量: %dM,可用物理内存 %dM\n", memoryStatus.ullTotalPhys/1024/1024, memoryStatus.ullAvailPhys/1024/1024)
	fmt.Printf("虚拟内存总量: %dM,可用的虚拟内存量 %dM\n", memoryStatus.ullTotalVirtual/1024/1024, memoryStatus.ullAvailVirtual/1024/1024)
