The mathematic model for optimization of the design parameters of cycloidal pump with singularity type of profile was proposed.

提出了异形齿廓摆线泵的优化设计数学模型，以单位体积排量最大为目标函数，以泵的连续传动条件、密封条件、强度条件为约束函数，创成系数和弧径系数为设计变量。

Leaf blade obovate-elliptic or oblong-lanceolate, 7-11 × 2.5-5 cm, margin large denticulate.

叶片倒卵状椭圆形或长圆形披针形， 7-11 * 2.5-5 厘米，边缘大的具小齿。

Leaves sub-basal, slightly distichous in seedlings and new shoots, erect, pale green, sometimes with pale spots in very young plants, linear-lanceolate, 15--35(--50)× 4--5(--7) cm, margin sparsely spiny-dentate, apex 2- or 3-dentate-pointed.

We studied the behavioral and endocrine responses of the fossorial social rodent, mole vole Ellobius talpinus Pall., to intrusions of strangers into burrow systems that were occupied by intact families.

我们研究了营掘地生活的社会性啮齿类——鼹形田鼠( Ellobius talpinus Pall。)对陌生鼠入侵完整家庭所占据洞穴系统后的行为和内分泌反应。

Relationship between DNA content and evolutionary degree DNA contents of bivalves were analyzed statistically with SPSS software at subclass, order, family and species grade respectively. Significant difference was detected between mean values of two subclasses according to the result of T-test. The DNA content of Heterodonta (3.77pg) was distinctly larger than that of Pteriomorphia (3.14pg). It was concluded based on ANOVA that the general trend of DNA content was to change from lower to higher values associated with evolution at higher taxonomical classification, i.e.

核DNA含量与进化地位的关系运用SPSS统计软件，在亚纲、目、科以及种4个分类等级上对双壳贝类的核DNA含量进行了统计分析。T检验结果显示，两亚纲核DNA含量的平均值有明显差异，异齿亚纲的核DNA含量平均值(3.77pg)显著大于翼形亚纲(3.14pg)，该结果表明，核DNA含量在较高的分类等级，即亚纲上表现出随着进化地位的升高显著增大的趋势。

Calyx teeth obsolete. Petals white, purple or greenish yellow, spatulate to obovate with a narrow inflexed apex.

萼齿不明显花瓣白色，紫色或黄绿色，匙形到倒卵形具一狭窄内折先端。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。
