篇文章中第三种滑法“灵动的舞步“http://www.kvkvk.com/article_s/402776c60100zuqs.html
如果包被滑的特别窄,包壁特别陡峭,trouph line的难度也是很大的,因为速度很快
。所以对于新手,要选比较圆的包来练习trouph line。
而zipline是竞技选手发现走trough会影响速度,因为trough一般是个圆弧,而不是

What happens to 2,4-D when it enters the body?
In humans, 2,4-D is not absorbed well through the skin or lungs, but it is
absorbed into the body if swallowed. Sunscreen, insect repellents, and
drinking alcohol may increase how much 2,4-D is absorbed through the skin.
Once inside, 2,4-D moves throughout the body but does not build up in any
tissues. The human body gets rid of most of the 2,4-D in the urine without

B5 passat
最近车front有点噪音,车启动慢开的时候吱吱的响,不影响开,但是很讨厌。就是们拴
生锈了开门那种声音。用手下压前段车身,就听得到这种声音,怀疑是shock absorber
,但是很快就弹回来了,阻尼还好,所以又不太像shock absorber。 怀疑是lower
control arm, 今天把车支起来看了一下,nnd,没看出任何异常,所有bushing都还好
。stablizer bar link的橡胶垫有轻微磨损,可能是stablizer bar link吗? 看了看
manual, shock absorber很难换,主要是要专门的工具卸弹簧。。而且我也不确定是it
的问题.
欢迎牛人指点。。

Zimbabwe to adopt Chinese currency?
Tuesday 7 September 2010
Zimbabwe’s Vice President Joice Mujuru on Monday suggested that the

adopt the Chinese Yuan.
Mujuru said China is now Zimbabwe’s biggest trading partner, with the Asian
giant absorbing most of the country’s mineral and agricultural produce and
this would “further cement the Look East Policy”.

Although several recent Western fighter aircraft are less detectable on
radar than previous designs using techniques such as radar-absorbent
material-coated S-shaped intake ducts that shield the compressor fan from
reflecting radar waves, the F-22 design placed a much higher degree of
importance on low observance throughout the entire spectrum of sensors
including radar signature, visual, infrared, acoustic, and radio frequency.

stealth fighter that could pose a significant threat to American air
superiority — and some of its technology, it turns out, may well have come
from the U.S. itself.
Balkan military officials and other experts have told The Associated Press
that in all probability the Chinese gleaned some of their technological know
-how from an American F-117 Nighthawk that was shot down over Serbia in 1999.
Nighthawks were the world's first s... 阅读全帖
