Traditional block has the construction requirements of constructional column, tensile inarch bar, castinplace concrete ring beam, and it is diffic ul t for construction and to assure the construction quality, moreover, the period is long. However, the core column and beam of new concrete hollow block with mac roporous lightweight aggregate adopt Ushape block to instead of traditional te c hniques. This technology reduces the process of formwork and binding reinforceme nt, and has the characteristics of convenient operation, rapid construction spee d, strong crack resistance, lower cost, and good insulation properties, and so o n.

摘要］ 传统的砌块有构造柱、拉结筋、现浇混凝土圈梁等施工要求，施工难度大、施工工期长、且施工质量不容易得到保证；新型材料大孔轻集料混凝土空心砌块芯柱以及芯梁采用 U形砌块代替传统工艺要求，减少了支模、绑扎钢筋等工序，还具有使用方便，施工速度快，抗裂性强、节约成本、保温绝热性能好等施工优点。

The results showed that the title compound more than the corresponding spiropyran one indoline ring system and had a melting point of 50℃ improved. It's general significant shifts in the λ=555nm of the absorption spectra of the open form and emission fluorescene properties were observed at 433nm.

In this article, weh ave utilized the ABEEM-σπ model to research this kind of reactions. Through regional softness values of both the atoms and π bonds, which are calculated by this model, we have interpreted properly the typical and particular stereoselectivity of Diels-Alder reaction. Furthermore, we also have initiatorily probed into the rationality and feasibility in terms of synthesizing heteroatomic -ring compounds using Diels-Alder reaction.

本文利用ABEEM-σπ模型对此类反应进行了研究，通过计算原子和π键区域的电荷分布和局域软度，结合局域硬软酸碱原理对Diels-Alder 反应的立体选择性给出了合理解释，而且还初步探讨了利用Diels-Alder 反应合成杂环化合物方法的合理性和可行性。

RESULTS: Anatomical observation revealed that, the flexor pollicis longus muscle was located in a ring structure consisted of sesamoid and intersesamoid ligament. When the first metacarpophalangeal joint over-flexed or over-extended, the extension tendon was apt to be injured because of augmental friction between sesamoid and the extension tendon.
