Former Sen. Alan Simpson (R-Wy.) weighed in on the Republican presidential
primary on Wednesday, calling Rick Santorum "rigid and a homophobic."
In an interview with CBS News' Bob Schieffer, Simpson faulted the Republican
field for making issues like same-sex marriage and reproductive rights
central to their platforms, warning that they would lose favor with voters
if the conversation does not change.

saying it will impose "substantial costs" on the economy.
Mr. Bachus's opposition to the Volcker rule, named after former Federal

Gas dryer应该是用semi-rigid transition duct还是用foil duct? 感觉传统上是用
foil,后来说有火灾隐患,但是现在的foil也是fire resistant了。懂的说说哪个好?

丰田2013年6月6日公开了预计将于年内作为2014年款投放市场的新一代“卡罗拉”(北
美版)的概要,价格及详细性能指标将在临近上市时发布。
这是第11代卡罗拉,为了吸引更年轻的用户而非维持以往用户,继“Avalon”
及“RAV4”之后,丰田再次采用了个性强烈的外观设计。前脸以较扁的前大灯以及下部
带大开口的保险杠等为特点,并搭配大幅膨出的翼子板以及向后平缓下滑的C柱。
新款卡罗拉的外形尺寸为长4639×宽1776×高1455mm,与上代车型相比车长增
加99mm,车宽扩大16mm,但车高降低10mm。轴距为2700mm,比上代车型长100mm。由于
轴距更长,因此后座臀点后移了75mm,另外还通过减薄前座靠背,使后座乘坐空间变得
宽敞。

“In the RX8 book, it says that the targets for bending rigidity and
torsional rigidity were the BMW 318i and the Lexus IS300. The RX8 is better
than the 318i, but less than the IS300 in bending rigidity. And it says that
it equals that of the 318i and IS300 in torsional rigidity.”

您好,让你久等了,用 " Body Rigidity " 做关键词。
VW网站上就有:
Body rigidity is one of the keys to the safety, comfort and durability of a
car. The less a vehicle "twists" on uneven road surfaces or when cornering
at speed, the safer its road characteristics are.
尼桑说:
Greater body rigidity reduces vibration for a more comfortable ride.

improving vertical rigidity to ensure a more comfortable ride

选取测量方法。
比如GPC有band broading,分辨率比较低,也就是说同一个polymer,如果只是PDI不同
,一个是1.01,一个是1.02,GPC上是看不出不同的,但是HPLC就可以分辨。
还有一点就是flexible polymer和rigid polymer他们如果从MALDI看分子量一样,GPC

看到陈年旧事又拿出来讨论,俺也码点字凑个热闹。
事先声明:我无意替任何人或机构说话,只是就个人经历给点注释,看官有公知或愤青
情节的免开尊口,或手下留情。若说偏见,我同情个人,同情机构,但是深恨那些个吃
人的、自私的先辈留下的、极坏的社会制度和游戏“潜”规则。
1)就这个事本身来看,个人觉得翻案是不可能的,中国这种事太多太多。据个人观察
,高能所没犯致命错误,没有徇私舞弊之嫌,即使公安部入驻,估计也查不出问题。或
许有人夹私,挤兑他一下,逼他走人,这在哪里都正常不过。不是说挤兑就合理,而是
说作为动物的人,免不了动物的根性。
2)在国内呆着,第一准则是先做人,再做事。怎么“做人”,你懂的。不懂说明你还
是小屁孩,先跟老人屁股混几年。想对事不对人,只管做事不管做人,路绝对是越走越
窄。除非你有权或有钱,或者你亲戚有权有钱,或者你傍上个有权有钱的主子。
3)目前国内的海龟政策一年一个变化,具体到各个单位,也非常的不透明,人情牌太
多。会来事的,本事即使不咋地,福利一样不少(住房、家属安置、内部经费、外部经
费、职称,等等)。不会来事的,即使满腔热血,也到处碰壁,撞得头破血流,福利是

来自主题: _Auto_Fans版 - Miata daily drive怎么样?
really nice autox! how can I find local autox events? (NC)
when you feel the uncomfortable vibration in the miata, that shows its low
rigidity, not hard suspension. s2k feels harsh but it's the whole car moving
along with road. For example, in the miata, if one wheel goes over a bump,
you feel a general shake because chassis flexes. In s2k, you feel the whole
car tilting up from that wheel. My experience anyway. The key is noise -- if
you hear vibration that's low rigidity. if you feel the whole... 阅读全帖

我这里想说的是
这个“需”的波动性
“需”不是rigid的,而是不断波动的
而且这种波动,不只是客观因素,如人口
还有可能是主观因素,如人们的品味、口味的变化
这种波动性,导致供需关系 governed下的交换价格变化非常大
所以,同样的劳动,其效益(产出的可交换价值)不停的在变
而一个人要改变自己的劳动习惯的时间,通常远远长于其所在行业的变化
因为有时候不幸运,就被淘汰了
这个时候就会怀念那种劳动产出很rigid的年代

12月 谈谈间谍问题
我一直感觉Reuters 有日本的间谍,他们会通过报道来传递针对华人屠杀的计划,和发
布不利于华人的报道,制造舆论。最重要他们后边的势力和犯罪集团有关。有必要好好
调查这个组织。
