Origin, developmental changes and homologies of the stage morphostructures were considered according to their location in three morphogenetic fields. The first, or central, field forms at the prodissoconch I stage. It can be inherited by prodissoconch II and nepioconch stages in one taxa, or PD-II, N and dissoconch stages in others. The second, or postero-dorsal, field appears at the N stage, and the third field, or antero-dorsal, at the D stage.
主要对3个形态发生区域的阶段形态结构的起源、发育变化和同源性做了研究,其一,即中央区域,开始形成于前双壳I期,在某个分类单元它可以在前双壳II期和幼贝期形成,而在其它分类单元则在前双壳II期、幼贝期和双壳期形成;第二区域,即背部后区,在幼贝期出现;第三区域,即背部前区,出现于双壳期。

However, grade II CT signs did not always result from type 2 occlusion; 21.1% of patients with grade II CT signs had type 4 occlusion. When the MCA trunk is short, the lateral group of the lenticulostriate arteries may arise from the M2 segment[2, 12]. In such cases, type 4 occlusion may also involve the lateral or posterior part of the putamen.
但是,II级早期CT征象(部分壳核后外侧区出现低密度)并非仅仅由2型大脑中动脉闭塞(包括部分豆纹动脉在内的大脑中动脉主干闭塞,豆纹动脉部分受累)引起;本研究中,21.1%深部大脑中动脉分布区出现II级早期CT征象(部分壳核后外侧区出现低密度)的患者,是因4型大脑中动脉闭塞(大脑中动脉M2段闭塞)引起的;这些患者的大脑中动脉主干均很短,因此外侧豆纹动脉群(lateral lenticulostriate arteries)是由大脑中动脉M2段发出的;此时,4型大脑中动脉闭塞(大脑中动脉M2段闭塞)也可以导致壳核后部或外侧部出现低密度(深部大脑中动脉分布区II级早期CT征象)。

Its high-capacity and strong-acid-resistance were proved. In the acid condition, the adsorption efficiency to acide green 6B and direct fast yellow RL reached above 90%. Through the adsorption rate curve on adsorption behavior of the three dyes, they were all according with pseudo-secondary adsorption rate curve. The rate constant of adsorption increased with increasing temperature. Through the adsorption isotherm of the three dyes, acide green 6B and direct fast yellow RL were according with Langmuir equation, while disperse blue 56 was according with Freundlich equation. The adsorption behavior was an endothermic process. Entropy was increasing during the adsorption. So raising temperature was in favor of adsorption.
