短增量敏感指数试验在耳蜗病变时，敏感指数可高达（） A.80％～100％ B.60％

一质量为m的小球以初动能E_k0从地面竖直向上抛出，已知上升过程中受到阻力f作用，图中两条图线分别表示小球在上升过程中动能、重力势能中的某一个与其上升高度之间的关系，（以地面为零势能面，h₀表示上升的最大高度，图上坐标数据中的k为常数且满足0＜k＜l）．则由图可知，下列结论不正确的是（　　）

A．①、②分别表示的是动能、重力势能随上升高度的图象

B．上升过程中阻力大小恒定且f=kmg

C．上升高度h=

k+1

k+2

h0时，重力势能和动能相等

D．上升高度h=

h0

2时，动能与重力势能之差为 k 2 mgh0

With hundreds of millions of electronic (161) taking place daily, businesses and organizations have a p incentive to protect the (162) of the data exchanged in this manner, and to positively ensure the (163) of those involved in the transactions. This has led to an industry-wide quest for better, more secure methods for controlling IT operations, and for deploying p security mechanisms deeply and broadly throughout networked infrastructures and client devices. One of the more successful concepts to engage the imaginations of the security community has been the development of standards-based security (164 ) that can be incorporated in the hardware design of client computers. The principle of encapsulating core security capabilities in (165 ) and integrating security provisions at the deepest levels of the machine operation has significant benefits for both users and those responsible for securing IT operations.

A．software

B．form

C．computer

D．silicon
