发帖数: 177 | 1 这个问题困扰了我很久，呵呵
做Column试验的时候，一般要先run一下tracer，从tracer的break through curve（
BTC）来fit一个dispersivity。理想情况下，因为tracer不会有任何反应，所以在1个
pore volume（PV）的时候BTC上对应的C/C0应该是0.5。但是由于试验操作上总会有一
点误差，尤其是pore volume，porosity以及pore velocity(v)的测量和确定，所以最
终BTC上C/C0=0.5对应的PV一般很少刚好在1PV上，多数情况下会大于1PV。
以前一位师兄告诉我，可以认为pore volume测得不准，通过调整pore volume使得C/C0
=0.5对应在1PV来得到相应的porosity和linear velocity，然后来fit dispersivity。
有的人同时fit dispersivity和velocity，这样其实就是默认pore volume和porosity
测得不准。也看到有的人在paper上发表的数据是同时fit dispersivity和retardation |

发帖数: 1222 | 2 实验中可以假定稳定流，那么流过一个pore volume的时间是稳定的，按照时间可以算
流过的pore volume。同时要量流出液的体积，根据discharge算实际流过的pore
volume。
假如是稳定流的话，按照mass (volume) 或者 time 来计算pore voluem 应该是一致的
。但是在实验的时候，如果样品粘土含量较高的话，在实验过程中会有膨胀，改变土壤
的饱和导水率和容积，所以流速会不稳定，这样按照时间测定和按照体积确定的pore
volume会不一样。如果使用沙子一般不会有这个问题。
Bromide做tracer是比较好的，实验中用tritium有时候会有些问题，虽然理论上
tritium应该是最合适的tracer. 我有时候用tritium会算出retardation = 1.3。很不
爽。
另外有一点，如果样品存在团聚体(aggregates)的话，用简单的ADE模拟会有问题，需
要用dual porosity 模型。
工程方面的研究总是用沙子来做土柱试验，一般不会有什么麻烦。可是如果用真正的土
壤或者地质样品的话，就会有许多意想不到的情况，也更难 |

发帖数: 4896 | 3 ADINA我知道，在volume建模上画网格，两个不同的模块，就是一样的网格，边线上都是一
样的node，但是如果是在solid建模上，话的网格就是不同的，就是是同一个点，也有两个
node编号，facel link也不好用。最后我都统统转化成volume才搞定这个问题。
但是volume不能进行布尔运算，所以我都是用solid先画模型，确定了形状再转换成volume。还有就是volume如果形状不规则就不能mesh，所以经常要返工把solid切成规则形状的再转。不过总比发现边线上不是同一个node要好多了。
我没大搞过ANSYS，你去琢磨一下ANSYS是不是也有这样的两套模型体系？ |

砥平里第一晚（2/13-2/14夜）
注岩里和原州 （2/14昼）

Amazon investigator resolved this claim on Sunday, January 1, 2012
Your Re-presentation:
Sunday, December 25, 2011 The buyer ordered HP TouchPad Wi-Fi 32 GB 9.7-
Inch Tablet Computer from me on November 30. This product is not an android
tablet. My description did NOT state it is an android tablet, either. The
buyer must have known this before he placed the order. I sent him the right
product, which was the same as what he ordered and as what I described.

发帖数: 1029 | 41 说big data就必须提到那几个V，有人说5个，有人说4个。俺觉得最重要的应该是其中
的三个：Volume，Velocity，Value。现在很多人谈big data一般主要讲value，但
是如果data的volume和velocity没有大或者快到传统算法没法用的情况下的话，也不
能算真正意义上的big data，而确实“只是size大了，也不是大数据”。至于什么领域
能够有“volume和velocity大或者快到传统算法没法用的”程度的data，其实还是蛮多
的。healthcare当然有，俺本人也是做big data health informatics，但其他领域，
比如：气象，金融，图像，石油钻井，等等，这里面data的volume或velocity也是不
能低估的。 |

Skyline 的解法貌似是（没记错的话）：
把所有的turning points 放在一起，根据coordination从小到大sort 。
struct turnpoint {
int ptr; //coordinate;
bool startOrEnd;
int volume
}
再用max-heap, 把所有的turning points扫一遍，遇到start turning point, 把
volume放入max-heap. 遇到end turning point，把对应的volume从max-heap中取出。
max-heap的max 值就是对应区间的最大volume
complexity是O(nlogn)
max-heap可以用multiset实现。 |
