在马元的《红衣系列》中，画家内在性在吸收了欧洲文艺复兴前期大师形式语言资源，同时也找到了它和自己的表达主题的整合方式，这主要体现于马元的造型语言要素中，有两种因素是需要特别指出的，这就是垂直线造型的强调运用和红色的强调运用。

The Mazhashan syenites in the Bachu area were formed in the Late Permian with the zircon SHRIMP age ranging from 286 to 277Ma, and these ages are consistent with the ages (300-260 Ma) of the post-collisional granites in the southern Tianshan orogen.

Methods The changes of contents of AGEs in plasma and the abdominal aorta and changes of VSMC of the abdominal aorta were investigated with methods of fluorospectrophotometry, immunohistochemistry, computer image analysis and transmission electron microscopy on streptozotocin-induced diabetic rats. Results From the fourth week, in diabetic rats, the contents of AGEs in plasma and the abdominal aorta increased, the relative area of α-SM-actin in the abdominal aorta decreased, the density of nucleus of VSMC increased, and mitochondria and rough endoplasmic reticules in VSMC increased.

A new general kinetic equation was derived in which the effect of the removal of condensation water was taken into account completely, and was applied to the polyesterification kinetic study of AA/HPHP and AA/NPG. It was found that the reaction order of self-catalyzed polyesterification was not constant. For these polyesterifications, the reaction order was 2.5 at a low temperature, while 3.0 at a high temperature.
