My Fairest Lady,

Breakfast:

白米粥在灶台上已经熬好了,切好的猪肝在冰箱里,味道已经调好。
起床后开火至微滚,加入猪肝,等到没有血丝的时候即可。

Lunch:

木瓜牛尾巴汤,还不够烂,起床后开火继续熬上。味道已经调好了。

大米高粱已经洗好了,在电饭煲里,已经加好了水。地瓜切好了在小
铁盆里。提前一个小时开电饭煲煮上,等到打滚的时候改到熬粥那一
档,加入地瓜,继续煮半个小时即可。

萝卜缨子洗好了,在塑料盆里。

黑米红豆洗好了泡在小铁盆里,起床后熬上粥。
Others:

有事打我的手机。

Love you,

mimi

清扬婉兮满月展

清扬婉兮满月好些时间了,不少朋友都问我们要照片。说实在的我们两个真的
是太忙啦,每天就只有四到五个小时的睡眠,根本就没有时间给小家伙拍照片
的。幸好这些天我妹妹学校放假但是还没有回家,于是过来给我们帮点忙。这
些照片也是妹妹的帮忙下拍的,不然的小家伙都长了这么大,连张照片都没有
的话还真不太说得过去。

本来还想写点说明的,可是还是没有能够挤出时间来。这个周末争取吧。

打个哈欠,我好困啊。

招个手儿,热烈欢迎。

嘿嘿,你看不见我。

看什么看,没见过美女啊?

露一小手我。

抱抱,要个抱抱啦。

Effect of Air Entrainment on Rheology

前两天收到在UIUC时候的导师的电子邮件,说是我2000年在UIUC完成的毕业论文,终于发表在ACI Materials Journal上了。虽然现在已经不再干这一行了,听到这个消息还是蛮开心的。特此该文章收录在BLOG里,纪念一下。

Title: Effects of Air Entrainment on Rheology
Author(s): Leslie J. Struble and Qingye Jiang
Publication: ACI Materials Journal
Volume: 101
Issue: 6
Pages: 448-456
Keywords: air content; air entrainment; concrete; paste; rheology; viscosity; yield
Date: November 1, 2004

Abstract:

The effects of air entrainment on rheological parameters were studied using cement paste. The addition of air-entraining agent increased the air content up to a saturation level, above which no further increase in air content was observed. With increasing air content, the yield stress increased and the plastic viscosity decreased. The increase in yield stress was an unexpected result because increasing air is well known to cause an increase in slump, and yield stress and slump are known to be negatively correlated (as yield stress increases, slump decreases). Two competing effects are proposed to explain the effects of entrained air bubbles on rheological parameters: the attraction of cement particles and bubbles to form bubble bridges, and a fluid response of air bubbles due to their deformability. Bubble bridges are proposed to dominate in the yield stress and the fluid response is proposed to dominate when the sample is flowing.
