某企业向手机生产企业供应触摸屏，手机生产企业要求供货产品生产过程的不合格品率P＜0.1%，企业在质量文件中规定对产品出厂检验的方法AQL=0.1%，手机生产企业检验水平为Ⅱ的一次正常抽样方案进行抽检，经过验收发现产品很少发生质量问题，年末在对供应商的评审过程中发现企业生产该产品的过程能力指数分别为C_p=C_pK=1.0，请回答下列问题。

针对企业的情况，应做的调整有( )。

A．出厂检验根据转移规则采用一次放宽抽样，减少成本

B．提高现有的过程能力

C．手机厂进货检验可以适当减少检验量

D．手机厂可对该企业产品进行加严进货检验

In many countries today, laws protect wildlife. In India, the need for such protection was realized centuries ago. About 300 B.C,  1  Indian writer described forests that were somewhat like national parks today. The killing of game beasts was carefully supervised（监管）. Some animals were fully protected.  2  the forest, nobody was allowed to cut timber, burn wood for charcoal,  3  catch animals for their furs. Animals  4  became dangerous to human visitors were caught or killed outside the park, so that other animals would not become uneasy.

The need for wildlife protection is  5  now than ever before. About a thousand species of animals are  6  danger of dying out, and the rate at which  7  are being destroyed has increased.  8 we took no measures to protect wildlife, some day our children would see no living creatures except man himself.

（8分）某实验探究小组为了探究物体的加速度与所受合外力之间的关系，设计了如图a所示的实验装置．该实验小组成员用钩码的重力作为小车所受的合力，用传感器测小车的加速度，通过改变钩码的数量，多次重复测量，可得小车运动的加速度a和所受合力F的关系图像，他们在轨道水平和倾斜的两种情况下分别做了实验，得到了两条a-F图线，如图b所示．

（1）图b中的图线____是在轨道右侧抬高成为斜面情况下得到的（选填“①”或“②”）．当钩码的数量增大到一定程度时，图b中的图线明显偏离直线，造成此误差的主要原因是       ．

（2）小车和传感器接收器的总质量m=    kg，小车和轨道间的动摩擦因数μ=   （g=1m/s²）
