平均错误

Moreover, an improved upper bound on the average MAP decoding error probability of linear Slepian-Wolf systems for stationary memoryless sources is derived. Based on this improved bound, we analyze the performance of Slepian-Wolf systems based on LDPC codes and random permutations, and prove that under some conditions, all but diminishingly small proportion of LDPC encoders and permutations are good enough for the design of practical Slepian-Wolf systems when the coding length is very large.

然后，论文在相关平稳无记忆信源下推导出线性Slepian-Wolf系统平均MAP译码错误概率的一个改进上界，并在这一改进上界的基础上，分析了基于LDPC码和随机置换的Slepian-Wolf系统的性能，证明了在一定的条件下，当编码长度非常大时，几乎所有的LDPC编码器和置换对于实际Slepian-Wolf系统的设计都是足够好的。

作者通过研究表明了人们经常错误地理解平均化的好处，并考虑了产生这种误解的几种影响因素

Results The main causes of nonunion of humerus fracture were mistreatment and unconsummated materials of internal immobilization.Of32cases,31cases were healing;the average healing duration was6months.

结果 肱骨骨折不愈合的原因主要治疗方法错误及内固定材料因素及固定不完善。32例中，愈合31例，占96.9%，愈合时间4～10 月（平均6个月）；未愈合1例，占2.2%。

The conclusions of the study were as follows: 1 Prompts to self-explain promoted procedural learning, procedural near transfer, procedural far transfer. But prompts to self-explain didn"t promoted students" success on the conceptual assessment. 2 Direct instruction on a correct procedure and the cause lead to greater procedural learning, procedural near transfer, procedural far transfer than direct instruction on a correct procedure only. The difference was remarkable. But it didn"t promote students" success on the conceptual assessment. 3 Self-explanation promoted the invention and using of various correct procedures. The subjects, which under direct instruction on a correct procedure and the cause condition, made further use of correct procedures and more averagely. Both self-explanation and instruction of the cause strengthened correct procedures and weakened incorrect procedures.

通过实验一和实验二，研究得出如下结论： 1、问题解决中促进学习者自我解释，对程序的学习、程序的近迁移、程序的远迁移有促进作用，但对概念知识没有促进作用； 2、教授一个程序及原因与只教授一个程序相比，对程序的学习、程序的近迁移、程序的远迁移的促进作用，前者显著优于后者，但对概念知识没有促进作用； 3、自我解释促进了多种正确程序的发现和使用，教授一个程序及原因条件下的被试使用正确程序的种类增多而且使用频率平均化，自我解释和教授原因都抑制了错误程序的发现和使用。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.
