《独立宣言》英文版
When in the course of human events,
it becomes necessary for one people to
dissolve the political bands which have
connected them with another, and to assume among
the powers of the earth, the separate
and equal station to which the laws Nature
and Nature’s God entitle them, a decent
respect to the opinions of mankind requires
that they should declare the causes which
impel them to the separation。

什么是痘坑,什么是瘢痕?
上一篇,讲了什么是毛孔?
今天#童彩虹# 继续来讲讲什么是痘坑和瘢痕吧,
瘢痕:
可以是因烧伤、手术、外伤、炎症等各种各样的创伤引起的。主要是因为破坏了正常的组织外观形态,同时组织病理发生改变。
瘢痕,一般分为萎缩性瘢痕、增生性瘢痕和疤痕疙瘩。我们生活中最常见的主要是前面的两种,瘢痕疙瘩是瘢痕中的一种少见的,特殊的类型(主要是一种特异性体质)。
痘坑:顾名思义,就是青春期或月经前后反复长痘痘后,皮肤产生炎症或感染,导致皮肤没有完全修复愈合好,而形成的凹坑。痘坑也属于瘢痕的一种,主要指的是萎缩性瘢痕。(少数严重的也会增生突起皮肤表面)
皮肤美容科最常见的瘢痕还是痤疮(青春痘)引起的。
痤疮反复或严重破坏皮肤时,组织在进行自我反复修复愈合的过程中,会发生纤维化和体积的流失,造成组织损伤,破坏了原本平衡的正常结构,于是皮肤的表面也会受到纤维束状组织(fibrous bands)向下拉扯,从而产生凹陷性瘢痕组织,在视觉上看起来皮肤纹理粗糙,在光影下看起来凹凸不平,从触觉上也会感觉皮肤粗糙,不够细腻,硬邦邦的缺乏弹性,非常影响一个人的容貌外观。
毛孔,痘坑,瘢痕,你分清了吗?
又怎么解决呢?感兴趣的可以留言#童彩虹#

【Ab Initio Calculation of Accurate Electronic and Transport Properties of Zinc Blende Gallium Antimonide (zb-GaSb)】
#论文# #半导体材料# #光学# #性质#
Gallium antimonide (GaSb) has emerged in recent years as a very technologically attractive semiconductor, given its applications in high-efficiency thermo-photovoltaics, mid-infrared lasers, photodetectors, high-speed electronic devices, and non-linear optics. This paper performs ab initio, self consistent calculations of electronic energy bands, total and partial densities of states and of effective masses for zinc blende gallium antimonide (zb-GaSb).
