Result:After removal of the bilateral lower molars, the remodeling and degenerative activities in different layers of the condyles increased, such as vesiculation of endoplasmic reticulum, distortion of mitochondria and increase of lysosome. Furthermore, the sequential arrangement of collagen fibrils was disturbed, the collagen network broke down and the proteoglycan granules decreased.

结果：细胞发生了不同程度的改建及退行性反应，如粗面内质网的扩张，线粒体肿胀，溶酶体增多等；基质中胶原原纤维的有序排列结构消失，胶原网受到破坏，同时蛋白多糖颗粒减少；基质中脂质小体及基质小囊等成分增多；负重区较非负重区的改变更显著。

Inthe last stage of reduction,the iron substrates formed on the surface of Wüstite areporous and permeable to gaseous diffusion.The reduction rate is controlled by thesurface reaction on the Wüstite-iron interface,but the rate of this surface reactionis limited by the velocity of CO formation.

在浮士体还原成金属铁的阶段，所生成的多孔性金属铁并不阻碍气相的扩散；还原的速率由浮士休-金属铁相界面的表面反应所控制，而表面反应的速率则受CO的生长速率所限制。

To make the wapiti sperm capacitated in vitro, we selected and used the method of sperm-up. By making the rate of acrosome reaction as a main index, and the sperm energy, the survial time and the fertilizated rate of wapiti sperm and hamster mature oocytes as auxiliary indexes, it were carried out to compare the effects of wapiti sperm capacitation in vitro under different temperature, different density of pyruvate sodium, caffeine and heparin and different culture medium.

对马鹿精子，使用上浮法诱导其获能，通过对顶体染色测定精子的顶体反应率并作为主要指标，同时以精子活力、精子存活时间和异种受精率为辅助指标，对精子的获能效果进行评价，以比较不同培养温度、丙酮酸钠浓度、咖啡因浓度、肝素浓度以及培养基对马鹿精子体外获能效果的影响。

Significant loss of GEMs was not observed but strong growth activities, formation of biofilm and zoogloea on the surface of immobile particles were observed via scanning electron microscope. The mechanical stability of the particles remained unchanged after nearly two-month operation.

在整个反应过程中，没有出现大量工程菌流失的现象，同时在固定化颗粒的表面以及浅层均观察到了大量工程菌菌体，固定化颗粒的表面还出现了生物膜和菌胶团，反应结束时，颗粒形态完好，强度满足本工艺条件下长期使用的需求。

The optimal idle time of polyreaction and gel time can be determined by changing initiator content,temperature and acetylacetone content to make sure the casting process can be done successfully.

通过改变引发剂用量、环境温度以及缓凝剂用量可以控制聚合反应的诱导期，从而保证浇注过程的顺利进行，有利于制备均匀性好、致密度高的反应烧结B_4C/SiC陶瓷坯体。

Acylamino compounds from AD were synthesized by cleavage of A-ring through NaIO4/KMnO4 oxidation, ring closure by amination, oximation with hydroxylaminechloride in C-17 position, and reduction of oxime in C-17 position and substitution with substituted acylchloride and carboxylic acids.
