演变

Recently, it has been found that some inducers such as retinoids acid and yeast containing Se can prevent and reverse PLGC of rats to some extent. But all of these data are obtained from animal experiments, information of clinical research has not been reported. Natural β-carotin and folic acid can reverse dysplasia and intestinal metaplasia of gastric mucosa to some extent, but these effects are required to be further investigated.

晚近发现维甲酸类诱导分化剂及硒酵母对大鼠PLGC演变至胃癌有一定阻抑预防和逆转治疗作用，但均仍停留在动物实验阶段而未用之于临床；天然β-胡萝卜素和叶酸干预治疗后能一定程度地逆转胃粘膜异型增生和肠化生，值得进一步深入。

Government and banking accounts in ancient Rome evolved from records traditionally kept by the heads of families, wherein daily entry of household receipts and payments were kept in an adversaria or daybook, and monthly postings were made to a cashbook known as a codex accepti et expensi.

古罗马的政府账目和银行账目则是从一些传统的账本演变而来的，这些账本由各家族头目保存着，以记事本的形式记录着家务的每日的开支，而月开支则汇集成一本现金簿——这就是赫赫有名的"收支薄"（古罗马用于管理家庭账目的账本）。

For Hu invariant moment having no scale invariance, two modified algorithms are proposed: one is based on the normalized central moment coming from the concept of image square and the other is based on constructing a new invariant moment.

主要贡献如下： 1。针对离散情况下Hu不变矩特征仅仅具有平移、旋转不变性，不具有比例不变性的问题，提出了两种改进算法：一种是从图像正方形概念演变而来的归一化中心矩的修正；另一种是重新构造新的不变矩特征。
