安氏隐孢子虫卵囊感染人结肠癌(HCT-8)细胞，Real-time PCR技术测定RPMI-1640培养液中分别加入不同浓度胎牛血清(fetal calf serum，FCS)、葡萄糖(glucose，GLU)、维生素C(ascorbic acid，ASC)、叶酸(folic acid，FOLIC)、泛酸钙(calcium pantothenate，CAPAN)和胰岛素(insulin，INSULIN)后虫体的增殖效果。

There are two modeling methods used in this research area, that is analytical method and numerical method. Analytical method can be used to analyze the sound pressure within enclosures, and to analyze the control mechanisms theoretically, however it can be used for regular cuboids only. Numerical modeling method can manage enclosures with arbitrary boundaries, nevertheless, the results obtained using this method are dispersed sound pressure. It is hard to conduct real time control with this method. The two modeling methods have their own inherent defects.

对于封闭空间的结构声辐射，目前有解析建模和数值建模两种建模方法，解析建模方法可以从理论上对系统进行分析，探讨消声机理，但它只适用于长方体等规则封闭空间；数值建模方法不受空间边界形状的限制，得到的是空间声压的离散结果，难以用于实时控制，两种方法都存在着局限性。

Methods BTXA labeled with125Iwas obtained. The radioactivitymeasurementwas taken tomeasure the solubility ofBTXA in gel and BTXA solution. The rightgastrocnemiusmuscles of12 SD ratswere injectedwithBTXA geland the leftgastrocnemiusmuscles injectedwith normal salinewere used as controls. HE staining and 1% gold chloride stainingwere used to study the tissue changes 6 months and 12 months afterBTXA gel injection and transmission electronmicroscopy was used to observe the ultrastructural changes.

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。
