There was not any distinct difference in flourrescence density between the experimental and control silkworms under the ultra-violet light in both of the 2 experiments; and with the excitation of ultra-violet ray, the germline cells of experimental silkworms in the experiment of 2002 emitted green fluorescence while the control did not.

紫外灯荧光检测，2次实验都未看到实验组与对照组家蚕间有显著差异，而2002年实验取家蚕4龄幼虫生殖细胞观察，有部分实验家蚤的生殖细胞在紫外光下发绿色荧光。

In the current design framework concerning two-color microarray experiments, random errors are usually assumed to be uncorrelated random variables in the statistical models used to construct designs, but it is often more reasonable to acknowledge that there could be some correlation structure among the random errors. Particularly, when the technical replicates are used in the experiments.

在与微阵列实验设计相关的研究中，大部分被用来建构设计的模式其误差项均被假设为不相关的随机变数，然而这似乎与某些实际的情况相违背，例如当实验中若使用所谓的技术性重复时，不同晶片的实验结果间就可能会产生相关。
