体育运动有益身心健康 The Advantage of Sports

Recently, more and more people stay at home watching TV and surfing the Internet, which leads to obesity and even get serious illness.

最近，越来越多的人呆在家里看电视、上网，所以导致肥胖甚至更严重的疾病。

This is no doubt that sport is good for our health. A person who takes exercises regularly will keep fit. What’s more, exercise can make you well-behaved and confident. If you usually take exercise with your friends, you will be close to them. After all, sports can make your life more colorful.

毫无疑问，运动对我们的健康有好处。人经常运动可以保持身体健康。更重要的是，运动可以使你表现得自信。如果你经常和你的朋友锻炼，你们之间的关系会更加紧密。毕竟，运动可以使你的生活更加丰富多彩。

Nothing is more important than doing sports. It's time to take actions to stay away from the TV and computer and to take part in sport activities.

没有什么比运动更重要。是时候采取行动远离电视，电脑和参加体育活动了。

② Linux内核的常量定义

宏phys定义了你的机器上的地址转换__virt_to_phys（）。这个宏用于把虚拟地址转换为一个物理地址。通常情况下：
phys = virt - PAGE_OFFSET PHYS_OFFSET 解压缩器的地址地址。由于当你调用解压缩器代码时，通常关闭MMU，因此这里并不讨论虚拟地址和物理地址的问题。通常你在这个地址处调用内核，开始引导内核。它不需要在RAM中，只需要位于FLASH或其他只读或读/写的可寻址的存储设备中。
l ZBSSADDR
解压缩器的初始化为0的工作区的起始地址。必须位于RAM中，解压缩器会替你把它初始化为0，此外，需要关闭MMU。
l ZRELADDR
解压缩内核将被写入的地址和最终的执行地址。必须满足：
__virt_to_phys(TEXTADDR) == ZRELADDR
内核的开始部分被编码为与位置无关的代码。
l INITRD_PHYS
放置初始RAM盘的物理地址。仅当你使用bootpImage时相关（这是一种非常老的param_struct结构）
l INITRD_ⅥRT
初始RAM盘的虚拟地址。必须满足：
__virt_to_phys(INITRD_ⅥRT) == INITRD_PHYS
l PARAMS_PHYS
param_struct 结构体或tag lis的物理地址，用于给定内核执行环境下的不同参数。 RAM第一个BANK的物理地址地址。
l PAGE_OFFSET
RAM第一个BANK的虚拟地址地址。在内核引导阶段，虚拟地址PAGE_OFFSE将被映射为物理地址PHYS_OFFSET，它应该与TASK_SIZE具有相同的值。
l TASK_SIZE
一个用户进程的最大值，单位为byte。用户空间的堆栈从这个地址处向下增长。
任何一个低于TASK_SIZE的虚拟地址对用户进程来说都是不可见的，因此，内核通过进程偏移对每个进行进行动态的管理。我把这叫做用户段。任何高于TASK_SIZE的对所有进程都是相同的，称之为内核段。（换句话说，你不能把IO映射放在低于TASK_SIZE和PAGE_OFFSET的位置处。）
l TEXTADDR
内核的虚拟起始地址，通常为PAGE_OFFSET 0x8000。内核映射必须在此结束。
l DATAADDR
内核数据段的虚拟地址，不能在使用解压缩器的情况下定义。
l VMALLOC_START
l VMALLOC_END
用于限制vmalloc（）区域的虚拟地址。此地址必须位于内核段。通常，vmalloc（）区域在最后的虚拟RAM地址以上开始VMALLOC_OFFSET字节。
l VMALLOC_OFFSET
Offset normally incorporated into VMALLOC_START to provide a hole between virtual RAM and the vmalloc area. We do this to allow out of bounds memory accesses (eg,something writing off the end of the mapped memory map) to be caught. Normally set to 8MB. pram——指定了RAM起始的物理地址，必须始终存在，并应等于PHYS_OFFSET。
pio——是供arch/arm/kernel/debug-armv.S中的调试宏使用的，包含IO的8 MB区域的物理地址。
vio——是8MB调试区域的虚拟地址。
这个调试区域将被位于代码中（通过MAPIO函数）的随后的构架相关代码再次进行初始化。
l BOOT_PARAMS
参见 PARAMS_PHYS.
l FⅨUP(func)
机器相关的修正，在存储子系统被初始化前运行。
l MAPIO(func)
机器相关的函数，用于IO区域的映射（包括上面的调试区）。
l INITIRQ(func)
用于初始化中断的机器相关的函数 。

③ 为什么我一打开黑手党2就出现PhysX SDK not initialized. PhysX System Software will be installed.咋解

用360或者在控制面板把NVIDIA的physx卸载了，再点击游戏，游戏会自动进行安装，之后就能进游戏了

④ 在matlab仿真时出现Initialization commands cannot be evaluated. MATLAB error message求大神帮帮忙~

你的这个PMSM模型是旧版本的
如果要在7.1里用需要转换
过程看这里http://www.mathworks.com/access/helpdesk_r13/help/toolbox/physmod/powersys/power_c4.html

⑥ Vb隐藏任务管理器中的应用程序

方法一、直接在窗体添加代码和一个按钮，按按钮后进程隐藏

'BOOL InitNTDLL()：初始化，加载相关DLL，并且获得相应函数的函数指针
'VOID CloseNTDLL()：和初始化对应，进行相应的收尾工作
'VOID (HANDLE hSection)：更改当前进程的session，使当前进程具有读写对应核心对象的权限
'HANDLE OpenPhysicalMemory()：打开所需的物理内存映象
'PVOID LinearToPhys(PULONG BaseAddress, PVOID addr)：把线性地址转换成物理地址
'ULONG GetData(PVOID addr)：获得所需的数据
'BOOL SetData(PVOID addr,ULONG data)：更改所需的数据
'BOOL HideProcess()：隐藏当前进程
'这其中HideProcwss()是最重要的函数，其他函数都是为了被它调用存在的，我们就从这个函数入手,剖析隐藏进程的原理
