I have several questions.
fuel rods are above the core.
control rods are under the core.
all fule rods, control rods, and core are
within a sealed containment.
how to push the fuel rods down to produce energy?
how to push the cotnrol rods up to stop the reaction? |

have to be controled by something outside of containment?

to save the plane, two people familiar with the investigation said.

x****u 发帖数: 12955 | 24
帮你保持平衡和防滑的东西。Traction Control是相对简单点的系统,它检测到某个轮
子打滑后就通过上闸,或者减小发动机功率来降低轮速,直到不再打滑为止。
Stability control相对聪明一点,可以检测到车子的姿态发生不合理变化。然后通过
对四个轮子转速度调整来达到恢复正确姿态和方向的目的。
你要是在多雪,或者多雨的地方住,这两个东西很有用。 |

现在开车比较正常,刹车也好用。
但是仪表盘的brake灯一直再闪,abs的灯一直亮
换过新的前面2副pads,还是没有解决。
是不是就是说一定是abs的问题了(sensor or??)
cruise control不好用,检查了对应的fuse也没问题。是不是因为brake灯再闪,导致
系统默认cruise control 就不能用???
如果,abs功能丧失的话,可不可以继续用? |

对着车reliability的评价,说Body control Module有可能会出小毛病。

f*******r 发帖数: 5301 | 35 对于toyota的系统而言,TRAC(traction control)和ATRAC(advanced traction
control,两驱上也叫auto-lsd)的主要区别在于:
TRAC会自动抑制电子油门,降低发动机输出,因为该功能为正常驾驶使用,为了避免冰
面打滑之类的情况,减小油门有助于控制打滑
A-TRAC不干预油门,因为这个功能只在4-LOW起作用,一般为攀爬或越障碍时使用,
防滑同时往往需要保持高扭矩输出
从原理来看,你后面说那个保持踩油门是没错的,对于ATRAC系统会自动刹车,不持续
踩油门则不能保持攀爬力,ATRAC系统期待用户保持持续的动力输出 |
