In this paper, a region approximation idea that means using a "fat curve" with a width to approximate the offset curve is proposed, and a complete set of algorithms to approximate offset curve using disk Bézier curve are given and implemented. In the algorithms, the optimal and uniform approximate curve of the offset curve as the central curve of the Disk Bézier curve is found by using Remez method, and then the upper optimal and uniform approximation principle is proposed to compute the error radius function of the Disk Bézier curve. Thus, the whole Disk Bézier curve can be obtained. In the end of this paper, the approximate effect of the Disk Bézier curve is not only analyzed and assessed, but also some specific examples are provided.

We cannot, if we would, play the part of China, and be content to rot by inches in ignoble ease within our borders, taking no interest in what goes on beyond them, sunk in a scrambling commercialism; heedless of the higher life, the life of aspiration, of toil and risk, busying ourselves only with the wants of our bodies for the day, until suddenly we should find, beyond a shadow of question, what China has already found, that in this world the nation that has trained itself to a career of unwarlike and isolated ease is bound, in the end, to go down before other nations which have not lost the manly and adventurous qualities.
虽然我们并不能,但若是我们在自己的国家扮演中国的那种在骄奢淫逸中一寸一寸的腐烂的社会角色,除了对自己,周围发生的一切则丝毫不感兴趣,沉浸各种乱七八糟的利益之中,不追求更高层次的生活,全无勤劳和冒险的渴望,每天只奔忙于来自身体的需求,我们会突然间发现,在疑团之外中国所已经找到的结局——在这个世界中,当一个国家把自身训练成并不好战并且把隔绝和安逸当作国界的时候,最终将倒在另一个富有勇敢的冒险精神的国家面前。

我们决不能扮演中国的角色,要是我们重蹈中国的覆辙,自满自足,贪图自己疆域内的安宁享乐,渐渐地腐败堕落,对国外的事情毫无兴趣,沈溺於纸醉金迷之中,忘掉了奋发向上、苦干冒险的高尚生活,整天忙於满足我们肉体暂时的欲望,那麼,毫无疑问,总有一天我们会突然发现中国今天已经发生的这一事实:畏惧战争、闭关锁国、贪图安宁享乐的民族在其他好战,爱冒险的民族的进攻面前是肯定要衰败的。

The release of CRH in stress response during menopause inhibited the secretion of GnRH, gonadotropic hormone and estrogen and induced the expression of intracellular HSP. As the growing of month, the expression of HSP70 and HSP70mRNA in uterus went up at the beginning and came down in the end. The result might be caused by the following:The increase of CRH and the decrease of estrogen during early menopause weakened the inhibitory effects on HSP.
本实验观察到随着大鼠月龄的增长子宫HSP70及mRNA的表达呈先增后降的变化,早期热休克蛋白的增加可能与CRH的增加及局部雌激素水平下降对HSP抑制作用的降低有关,但随着组织器官的衰退,其蛋白合成能力下降,因而表现出晚期热休克蛋白及基因表达下调。
