求三个专业名词的精确翻译和简单含义

1.在1997年KELEJIAN  AND  PRUCHA写的文章《A  GENERALIZED  MOMENTS  ESTIMATOR  FOR  THE AUTOREGRESSIVE PARAMETER IN  A  SPATIAL MODEL》中多次出现专业术语 triangular  arrays ，如这一段：
     The  proof  of  Theorem  2  requires  a  central  limit  theorem  (CLT)  for  triangular arrays. The CLT below follows readily from a corollary to the Lindeberg-Feller  CLT for triangular  arrays  using  the Cramer-Wold device. That corolla~yis, for example,
given in Billingsley (1979, p. 319, Problem 27.6)。
请问triangular  arrays 的专业术语准确翻译是什么？具体含义是什么？


2.在贝叶斯分析中经常见到 “diffuse prior”。它应该怎样翻译，简单含义是什么？
3.在异方差分析的文章中，又看到一个单词“cell variances”。它应该怎样翻译，简单含义是什么？

1.第一个名词：三角形数组
Triangular arrays are a unifying thread throughout various areas of discrete mathematics such as number theory and combinatorics. They can be used to sharpen a variety of mathematical skills and tools, such as pattern recognition, conjecturing, proof-techniques, and problem-solving techniques. While a good deal of research exists concerning triangular arrays and their applications, the information is scattered in various journals and is inaccessible to many mathematicians. This is the first text that will collect and organize the information and present it in a clear and comprehensive introduction to the topic. An invaluable resource book, it gives a historical introduction to Pascal's triangle and covers application topics such as binomial coefficients, figurate numbers, Fibonacci and Lucas numbers, Pell and Pell-Lucas numbers, graph theory, Fibonomial and tribinomial coefficients and Fibonacci and Lucas polynomials, amongst others. The book also features the historical development of triangular arrays, including short biographies of prominent mathematicians, along with the name and affiliation of every discoverer and year of discovery. The book is intended for mathematicians as well as computer scientists, math and science teachers, advanced high school students, and those with mathematical curiosity and maturity.
2.“diffuse prior “扩散先验” 。
3.“cell variances含义为方差协方差矩阵元素中的方差项 Test allows for unequal cell variances   

1、三角形数组 （一种阵列） 2、扩散先验概率  3、列阵值间差异（单位列阵方差）

首先感谢您的回答：
1.第一个名词回答和解释欠妥，这样解释与he  proof  of  Theorem  2  requires  a  central  limit  theorem  (CLT)  for  triangular arrays怎么联系？
2.“diffuse prior”确实翻译为“扩散先验”，扩散先验分布指的是先验分布不是正常的密度，不可归一化。
3.“cell variances”翻译为“列阵值间差异（单位列阵方差）”。这样的翻译让人找不到北，中文的含义更搞不清楚了。

晕，还是没有找到精确答案！
