来自主题: Automobile版 - 求助:有没有人修过shifter linkage?
突然点不着火和shift linkage有啥关系?怕是被宰了。
Shift linkage点不着火的情况是在档位不能正确在P档(自动车)或N(手动车)的时
候车自动防止点火启动的情况。不是说不可能,但是如果是突然出现的话,可能性比较
小。
labor当然也不需要7个小时。

wiper linkage脱臼了,今天匆匆忙忙拆下来看了看,过几天换。最后定位时打算启动
刷单次功能,此时linkage最后关节位置应该到达一个极值,再将 wiper arm 安装到归

不是很清楚shift linkage是什么问题,不过如果是P档打不着火,N档能打着火的话,
一般是transmission里面的线路需要清洗一下,dealer那里做都只需要几十刀就够了

来自主题: Programming版 - a c++ question for template
there is no "static linkage". there's only 3 types of linkage: external,
internal and no linkage. external linkage object can be referred in other
translation units, internal linkage can be referred in the same translation
unit but in different scope, no linkage can't be referred outside the scope.
whatever static linkage is, both template and macro can be external or
internal linkage. mixing macro and linkage are vague and not strict anyway,
since macros are not seen by compilers at all.

最近由于舟子视频惹得祸,搞得大家对口音心神不宁。好像大家对我的录音反应还
不错,录音见:
http://www.mitbbs.com/article_t/WaterWorld/1642421.html
应大家要求,我来写一个口音通俗教程,以抛砖引玉。
1.口音的成因
无论是哪种语言,都会出现南腔北调的状况。我觉得最早造成各种语言口音特色的
主要原因是天气。主要的趋势是北方偏冷的地方,如俄罗斯,北欧三国,英国,德国等
等,都偏后硬腭音。发音清而脆,短促爆破。主要目的,是避免浪费热量,保暖。俄国
人就是典型例子,不把每个词发到喉咙根后不罢休,因为真的很冷。然后往南走,到了
意大利,西班牙等南欧地区,辅音以浊辅音为主(如西班牙语和意大利语里k->g; t->d
, etc),元音都很圆润,语调都很抑扬。再到非洲和印度和南亚热带地区,能明显的感
觉到发音部位变成口腔前部和嘴唇音(如典型的非洲u音)。清辅音完全不存在。因为
真的很热,你试试蒸个桑拿或者跑个几千米,大汗淋漓的时候再跟人说个话你就知道这
中口音的变化了。

more confused now.
so inline keyword is a message from the coder to the compiler about two
things: 1) code expansion, which is a suggestion. the compiler can
either honor it or not; 2) external linkage, which is a requirement.
otherwise odr is violated.
but if the compiler doesn't honor 1), how could it meet 2)?
the following article says inline functions by default have external
linkage. is it possible to use another type of linkage? how?

来自主题: Biology版 - 也来说说GWAS
我不明白你说的control指的是什么,可能我们指的不是同一个东西?
典型的linkage analysis的方法IBD (Identity By Descent)就是用pair of affected
siblings. 我所说的case only是说没有unaffected (normal)subject参与统计。
有人可能会好奇,为什么没有control也能做出来。我们从linkage这个词就能看出这一
点。Linkage,严格来讲指的是两个位点之间的关系,离得近的两个位点在遗传的时候
更倾向于在一起。如果一个marker位点离真正的致病基因很近,就会有很强的linkage
。如果没有linkage关系,这个位点跟致病基因会以1/2的概率一起遗传。如果能找到一
些位点以高于1/2的概率跟致病基因一起遗传,不就可以说明致病基因在这些位点附近
了嘛。可是问题是,我们并不知道致病基因在哪儿,知道了我们就不用做这些事了。幸
运的是,我们可以用是否得病来代替致病基因的状态。当然,如果致病基因跟是否得病
的关系比较弱,那这个替代就会不准,这也是为什么linkage analysis在effe

what i said about linkage is for "global" const, i.e. in the global
namespace scope. const data member in a class is in class scope. they don't
have linkage. const static member has external linkage if the class has
external linkage.
const member will take a part of the object memory. it will be initialized
when the object is initialized (i.e. in ctor).

我的是两个都不转了,然后拆开dash garnish cover,linkage应该就在里面,我的是
两个可以协调工作,电机也转,但是雨刷不动,然后又把那个linkage塔上,就能用了,
我后来又在雨里试了试,没有问题。其实很简单。
我觉得主要是缺少grease,那个里面好像有个孔用来放grease的,我还没有放。
另外这个设计挺科学的,我不是学汽车的,瞎猜。多数情况下,如果玻璃上有水,
摩擦比较小,所以电机带动雨刷并不吃力,但是如果玻璃上没有水了,这时摩擦力
增大,如果电机仍然带动雨刷转,比较吃力,如果是刚性连接,可能会烧毁电机。
但是在没有烧毁电机前,linkage先脱掉(我就是这种情况),保护了电机。
不确定这个方法是对的!但是我想不出其他的连接方法。
拆开dash garnish cover要先把两个wiper arm谢下来,注意标记左右位置。
去找一本维修手册,会教你如何拆它的。

通俗地讲,我们是看得病的人和他没有得病的亲戚之间有哪些位点是不同的
