The exacerbations and remissions will be indicated by the diseases, the seasons of the year, the reciprocation of the periods, whether they occur every day, every alternate day, or after a longer period, and by the supervening symptoms; as, for example, in pleuritic cases, expectoration, if it occur at the commencement, shortens the attack, but if it appear later, it prolongs the same; and in the same manner the urine, and alvine discharges, and sweats, according as they appear along with favorable or unfavorable symptoms, indicate diseases of a short or long duration.

根据疾病本身、季节变化、周期交替——无论是每天、每隔一天或更长时间——以及根据意外出现的症状，即可看出疾病是恶化还是解除。以胸膜炎病症为例，若咯淡出现于初期，则疾病不会长久；但若出现于后期，则疾病将会拖延。同样，根据大小便、出汗的现象及与之相伴的有利或不利症状，即可知患病时间之长短。

Nowadays most of researches on the multicast routing are how to generate multicast tree. In case of multicast tree failure, there need to re-route all of nodes behind the failure point so much as re-build the whole tree, this will deteriorate Quality-of-Service, on the other hand, it is insufferable in some multicast applications. We proposed a Fault-Tolerant multicast scheme to resolve this problem. Our scheme creates backup paths crosswise in the ramose node. It can reduce additional cost greatly and recover the failure of multicast tree rapidly.

现在关于多播路由的研究大多着眼于多播树的生成，一旦多播树出现故障，就需要对故障点以下的所有多播接收节点进行重新路由甚至对整个多播树进行重新构造，这一方面降低了服务质量，另一方面有些多播应用不允许长时间的中断，对此本文提出了一种多播容错方案，采用在分枝节点之间建立备份路径的措施，可以在很大程度上减少额外的代价，能够在最快的时间内恢复多播树的故障，并使得恢复后的多播树形状基本上没有改变。

From the commercial consideration, the incubation time was fixed at 3 days and reinvestigated by RSM. The maximal keratinase activity was obtained from the following condition: tryptone 0.16%,yeast extract 0.27%, feather 0.08%, incubation temperature 51.7С.

由於长时间培养容易造成污染，且不具经济效应，因此将反应时间调整为3天，进行第二次的RSM分析，得到之培养条件为：tryptone 0.16 %， yeast extract 0.27 %， feather 0.08 %及 temperature 51.7С。
