显的弱点,它的反应模式是固定的。具体说,Torsen差速器一般提供1:3的Torque分配
,如果两轮间的Torque差别过大,也会出现打滑,这时就不如电控系统了。
泛一点说,纯机械系统在适合它的简单应用下,确实比机电系统反应快,这是没有疑问
的。机电系统的瓶颈也是在机械的actuator。但有两点。一是机电系统做得好,也能接

yes the supercharger is driven directly by the crankshaft
but boosting then depends on engine speed
which means, when your engine works at a low to medium output,
for example, hwy cruising at 70mph and some 2000ish rpm, and you suddenly
kick down for maximum output, you still need to build up rpm in order
the supercharger can do its best feeding air into the cylinders.
this process will be shorter compared to that of a turbo engine,

1个月前发现有的时候加速的时候有比较清脆的那种铃铛响,有的时候不响。车过颠簸
路面的时候倒是不响。今天去dealer service,告诉是长期用regular的油,不经常开
的话,油污使喷油不有效。车上电脑在compensate的时候,oil injector发出这种声音
。做了fuel induction service, removes accumulated deposits from fuel
injectors, ports, intake valves, manifold and combustion chamber. 但是做完
service之后,响声依旧。Service说就这样了,不影响开车,没有什么问题;如果有条
件用好的油,虽然manual说regular就可以。

本文介绍的是在哲学和逻辑学中的归纳法。归纳推理是对演绎推理的补全。關於其他也
被称为归纳的主题,詳見「归纳法」。
归纳法或归纳推理(Inductive reasoning),有时叫做归纳逻辑,是论证的前提支持结
论但不确保结论的推理过程。它基于对特殊的代表(token)的有限观察,把性质或关系
归结到类型;或基于对反复再现的现象的模式(pattern)的有限观察,公式表达规律。
例如,使用归纳法在如下特殊的命题中:
冰是冷的。
弹子球在击打球杆的时候移动。
推断出普遍的命题如:
所有冰都是冷的。
所有弹子球都在击打球杆的时候移动。

有效的:
所有观察到的乌鸦都是黑的。
所以所有乌鸦都是黑的。
这例示了归纳的本质: 从特殊归纳出普遍。结论明显不是确定的。除非我们见过所有的
乌鸦 - 我们怎能都知道呢? - 可能还有些罕见的蓝乌鸦或是白烏鴉。
