下面這17種複方是用在擴香器的。將適量(通常是10滴或20滴)的精油放在深色玻璃瓶中
完成複方。然後照著擴香器的製造商指示,滴入適量的複方精油在擴香器中。
記著,為了安全一定要確定使用聲譽好的精油供應商的精油,如香草魔法學苑(哈,這一
句是我加的)也要了解自己本身的精油禁忌(如:孕婦)。一開始時,先使用小量的複方
來確定自己是否喜歡這個味道,然後再加倍。請記住在使用擴香器時,要小心分子較大的
精油(如:香根草,廣霍香,橡樹,檀香,安息香)以免吸不動。
請自行查明複方中精油的使用限制及安全規範。請注意下面這些複方只是個人氣味享受用
,
並沒有任何生理及心理的療效。

还有就是在网上看了LAVENDER,好象有几种,Lavender 40/42 blend, Lavender

among those? It seems like the certified organic one is kinda

偶是这方面新手,请多指点.

s*******y 发帖数: 384 | 3 何謂擴散器(diffuser)?
擴散器是一種特殊的空氣幫浦,專門使精油分子散發到空氣中所設計的,這是最有效蒸
發精油,而不會傷害或改變精油的分子的方式。冷空氣擴散器是將精油轉化成空氣中微粒
水氣,以至於可以懸浮在空氣中幾個小時,不像使用芳香蠟燭或蠟燭蒸熏台,擴散器不會
對精油有加熱作用而傷害到精油脆弱的成分或甚至產生有毒物質。
擴散器的主體是玻璃噴霧器,借著一個彈性管和一個空氣幫浦相連,有很多種不同的設
計,但是效果一般來說都相同。如果你尚未擁有這種芳香擴散器,也可加入幾滴精油到有
噴頭的瓶子中,加入蒸餾水,然後搖晃均勻後噴灑在整個房間。 |

1. Diffuser: diffuser的主要作用就是遮光.Portable的diffuser通常就是一块白色,
可折叠,微透明的板.diffuser在风景摄影中主要是用在微距摄影.比如在晴天中拍摄一
只蝴蝶.因为光线太亮,背景会很亮.在这种情况下,可以用diffuser在蝴蝶上方将光线遮
挡一下.
2. Reflector: reflector的作用是将光线反射到主体. Reflector有金色和银色两种:
金色主要用在风景摄影中,而白色用在人像摄影中. 在主体背光或侧光时,可以用
reflector将光线反射到主体上,使得主体有合适的光源,
3. Polarizer: a polarizing filter will decrease reflections and glare from
glass, water and other reflective surfaces. 主要用于拍摄湖面.也可以用来拍摄
天空,使天空看起来更蓝.
4. White balance filter: 价格不菲的滤镜. 通常用在胶片摄影中.

The average distance that each type of molecule travels from
its starting point is proportional to the square root of the time involved:
that is, if it takes a particular molecule 1 second on average to go 1 um,
it will go 2 um in 4 seconds, 10 um in 100 seconds, and so on. Diffusion is
therefore an efficient way for molecules to move limited distances but an

但是我觉得这个经济/产业革命的发生,更像一个 drift-diffusion model(类似有x一

是随机的,短时间看 diffusion 部分起得作用很大(dt比较小的时候,drift近似不变

"I don't have a very good or pleasant experience with this store. I placed
my order in the morning on Tuesday 4/23, by Friday 4/26 I have not received
any tracking nor shipping confirmation from the store. Called their 888
number, got transfer about 3 times, finally after 15 minutes hold, I was
told that there was a delay from Nikon. Why on earth did they take my order
and have nothing in stock ? This is not a very good practice, wasted 3 days
and ended up order from somewhere else.

他们用的diffuser大小没错,因为这东西的size是跟想拍的object有关系,object越大
diffuser就要大. 唯一问题就是diffuser太大然后光失去了power,毕竟被分散了嘛。 |

什么是hybridization? 是不是ligation(我是生物盲, 别笑, hehe)?
这个可以作些理论估计的:
hybridization时间可以分成几部分: T_d+T_s+T_l
其中T_d是diffusion time, 也就是两条链相遇的平均时间;
这个时间和分子浓度有关系, 大致是这个分子diffuse出分子平均占有体积的时间.
平均占有的体积是浓度的倒数. 随即扩散出一个一个特征距离x, 扩散理论的结果是:
x^2=D*t, D是扩散系数, t是扩散时间. 扩散系数和温度, 溶液粘滞系数, 扩散体的
尺寸有关系. 固定温度和固定溶液下, D和扩散分子的尺寸R成反比: D正比于R^(-1).
于是T_d正比于C^(-2/3)*R, R是链分子的coil size, 它和链长L的关系是:R=Sqrt[L*b],
b代表链的弯曲弹性---b越小, 链越软. 这里的结果对柔软的长链尤其正确.
于是对特定的分子和特定的浓度来说: T_d正比于L^(1/2).
T_s是self diffusion time, 也就是相遇后调整构型使得端对端相吻合的时间;
这个时间大致是分子 |

v*****s 发帖数: 20290 | 45 我知道的这个方法就是测分子在溶液里面的diffusion constant,还是make sense的。
你这么想两个极端情况,分子完全不动,那你的time trace要么是0,要么是1,反正是
个constant,time correlation是1,分子动得特别快,time trace都是从0一下子跳到
1,或者从1一下子跳到0,time correlation是0。其他时候介于两者之间,分子扩散越
快,time correlation越小。其中还有一个参数是分子体积,如果分子体积已知,就可
以算diffusion constant,反过来如果diffusion constant已知,就可以算分子体积。
不知道怎么测细胞。 |

Your comments are so interesting. If you do not know the science, just be
patient and wait for more answers.

实dispersion与convection的含义倒是有点接近。diffusion一般翻译成扩散,主要指
分子扩散,比如催化剂内部的气体扩散。而dispersion则一般翻译成弥散,扩散。这个
单词一般不用于气体在催化剂颗粒内部的扩散,以及溶质在溶剂中的扩散,以气固流化
床为例,气体在整个反应器尺度范围内的组分扩散(弥散)经常用dispersion来形容,
而这种dispersion在很大程度上包括了对流扩散,它主要是指气体组分在反应容器内的
迁移,而一旦气体进入固体,就要用diffusion而绝对不能用dispersion了 |
