+0x1f8 XStateSave : Ptr32 _XSTATE_SAVE
KTHREAD的成員實在是太多了，所以只對KTHREAD的主要成員進行講解：
+0x000 Header：凡是以Header開頭的內核對象結構體，都是可等待對象，可以被WaitForSingleObject()函數等待
+0x028 InitialStack
+0x02c StackLimit
+0x030 KernelStack
以上三個成員跟線程0環堆棧相關,當使用中斷門或調用門提權進入0環時堆棧會被切換，堆棧信息來自於TSS中，TSS只有一個，而每個線程都有一個棧，所以當前是哪個線程在運行，就將哪個線程的棧複製到TSS中，這幾個成員在線程切換的時候仍然有用
+0x088 Teb：線程環境塊，位於用戶地址空間，3環時，fs:[0]指向TEB，0環時，fs指向KPCR
+0x068 State：線程狀態，就緒、等待還是運行
+0x135 BasePriority：它的初始值是所屬進程的KPROCESS裏面的BasePriority，以後可以通過KeSetBasePriorityThread()函數重新設定
+0x0C0 WaitBlock[4]：WaitForSingleObject或WaitForMultipleObject等待的內核對象
+0x0bc ServiceTable：指向系統服務表基址
+0x128 TrapFrame：進0環時保存環境
+0x13a PreviousMode：某些內核函數會判斷程序是0環調用還是3環調用的
+0x1e0 ThreadListEntry：雙向鏈表，一個進程所有的線程都在裏面，一共有兩個這樣的鏈表
