论述园林工程施工组织设计的编制程序。

某实验小组为了探究通过电阻的电流跟它两端电压的关系，设计了如图所示的电路（电源电压3V恒定）。

（1）请你根据电路图，用笔画线代替导线在图中完成实物电路连接（要求电表选择合适的量程，导线不能交叉）。

（2）连接电路时开关应 ，闭合开关之前滑动变阻器的滑片应处于_________端（选填“左”或“右”）。

（3）闭合开关，调节滑动变阻器得到如数据：

①该定值电阻的阻值R=____Ω。

②从实验可以得出：通过电阻的电流跟它两端的电压成_________比。

③第3次测量时，滑动变阻器连入电路的阻值是____Ω。

（4）探究之余，他们又想知道“电流与电阻的关系”，则他们在探究过程中应该通过直接控制_________不变、改变__________的方法获取数据，直接得出电流与电阻的关系。这其中运用了____________的方法。

眼外肌共有______条，其中______条直肌，______条斜肌。
