However, it is not actually right. Sebum suffers from acne stick-shape bacteria, egg-shape spore bacteria, and staphylococcus, then hydrolyze the glycerin three fattiness, giving birth to many dissociate fatty acids, which can make cilia and its surroundings have non-particularity-inflammation reactions. When the cilia wall micro-breakdown and dissociate fatty acid interring into hypodermis, the inflammation reaction gets worse.

事实上，青春痘是皮脂受痤疮棒状杆菌、卵圆形糠秕孢子菌、白色葡萄球菌脂酶的作用，水解甘油三脂，产生较多的游离脂肪酸，这些游离脂肪酸能使毛囊及毛囊周围发生非特殊性炎症反应，当毛束壁的极微崩溃及游离脂肪酸进入真皮后，即加剧炎症反应。

Otherwise, the control of remelting processing parameters of the SiCp/Al composites with a amount of Si in the master matrix, using the kinetics expressions, can be suitably achieved, whereas SiCp/pure Al composites could not.

Ti对SiC/Al界面反应有一定的抑制作用，但不能有效地控制多次重熔过程中SiC/Al间的界面反应，其原因在于局部熔体结构导致的Ti的微观不均匀。

The mechanism of dioxygen oxidation of NTS to DNS in alkali solution under mild condition was inquired into. The result showed that the key step in the preparation of DNS from NTS was the formation of 4-nitro-2-sulfobenzyl anion as a result ionization of NTS in strong alkali and then oxidization to 4-nitro-2sulfobenzyl radical by activated dioxygen.
