莫友芝《解连环》释读

莫友芝（1811—1871）是清代著名的学者，也是宋诗派的代表诗人之一，后人对他在版本目录学与诗歌上的成就颇多注目，而于其词作甚少留意。其实他《影山词》中所收的百馀首词，有不少情深意邈、夺心荡魄的佳作，《解连环》且口是其中之一：

Performance evaluations on inner vs. outer decomposition first parallel join algorithms for two nested loop joins

Two popular traditional join algorithms and their parallel versions are introduced. When designing join algorithms in serial computing environment, decomposing inner relation is considered as the right direction to save disk I/Os. However, two different decomposition algorithms are compared, such as inner vs. outer decomposition first algorithms for tuple-based and block-based nested loop joins, showing that the proposed approach is 20% better than general approach. Also lemmas are proved, when we have to use the outer decomposition first parallel join algorithms.

Freeze-thaw bond properties of new-old concrete

Using composite cubic specimens of new-old concrete,the bond splitting tensile strength and failure mechanism for the interface of new-old concrete in saturating state were explored when exposed to freeze-thaw cycling. Specimens were experienced for 0,25,50,75,100 and 125 freezing cycles. The roughness and adhesion agent including cement paste,cement mortar and cement paste with 10 percent of UEA expanding agent were also investigated. The test results indicate that the bond splitting tensile strength decreases with increased numbers of freezing-and-thawing cycles. The roughness and adhesion agent have different effects on the bond strength.

古代文人有趣绰号多“随诗”

宋朝词人贺铸写的《青玉案》一词中，有“试问闲愁都几许？一川烟草，满城风絮．梅子黄时雨”。这几句用三种景物比喻愁思多．极为巧妙，因此，贺铸得了一个典雅的绰号：“贺梅子”。词人张炎写的《解连环》一词中，有“自顾影欲下寒塘，正沙净草枯，水平天远。写不成书，只寄得相思一点”。人们都称张炎为“张孤雁”。

山河岁月

我生何恋？每山河赏阅，愉心舒眼。更饱览、邹峄风光，问造化沧桑，亿年如幻。奇石灵岩，或许是、龟骸鲸卵。念秦皇佚刻，风霜浸没，昔时璀璨。惊心岁华荏苒，笑平生劳碌，何悔何怨。且忘却、庸琐烦愁，结游侣登高，兴浓行健。偶倚嶙峋，彼此看、一样狂狷。翠岚浮，空阔幽嵬，海天望断。
