自组网的经典设计方案是让每一个终端节点随机选择另外一个节点进行数据的传输。
Typical designs for AD hoc networks have each end-node randomly select another node to pass its data onto.
顺便提一句，加沙人，正如瑞典宜家的设计师，让他们自己的文化能够进行全球选择的随机组合。
Not incidentally, Gazans, like that Swedish Ikea designer, made their own culture from the bricolage of global choices.
但是，如果在将实验的设计原则应用于Web数据收集过程时您更加主动(例如，在您的Web民意测验过程中随机选择投票者)，那么可以改变这种情形。
This can change, however, if you become more proactive in applying experimental design tenets to your Web data collection procedures (such as, randomize the selection of voters in your Web polls).
方法：采用专门设计调查表，对随机选择自愿参加个人无偿献血人员共962人进行调查。
Methods: Using specially designed questionnaire, randomly selected pairs of voluntary unpaid blood donors to participate in a total of 962 individuals were investigated.
报告的一个局限性就是观察设计没有随机化，可能误导为选择偏倚。
One limitation of this report is the lack of randomization for any observational design that can mislead for selection bias;
