No significant differences in the patient demographic data between the two groups were observed.

A demographic analysis indicates that most of our members are dental assistants.

一份人口统计分析表明我们的大多数成员都是牙科助手.

The variety is different from the typical one by having larger and thicker leaves with crenate or dentate margin, broadly winged petioles, broad-obovate or oblanceolate and serrate bracts, and lilac corollas with longitudinal yellow stripes in the throat.

该变种与原变种不同在于叶大而厚，边缘具圆齿或牙齿，叶柄具宽翅，苞片宽倒卵形或倒披针形，有锯齿，花冠淡紫色，喉部具黄色纵纹。

The 2nd modification ( 1964) preserves the dentate margin and anal transitional zone ( acute anal sensation), thus greatly improving defecatory control.

第一次保留了肛提肌，第二次保留了齿线和肛管移行区（肛管感觉），从而大大提高了排便控制能力；

By means of variable substitution and iterative method, this paper puts forth some new higher-order differential equations, and gives their formula of reduction of integrals to common denominator.

借助变量代换、迭代等方法，提出几类新的高阶常微分方程，给出其相应的通积分公式。

But to find a common denominator where we can all talk, where we don't find ourselves divided by religion or culture anymore, because we've got down something so essential.

我们所找的共通之处可以使我们彼此交流，让我们发现我们，不再被宗教与文化分隔开来，因为我们已经获得了最本质的东西。

Humour has to be shared-you need to find a common denominator and it should never be focused on one person.

幽默应该是与人分享的你应该找到一个共同点，而且永远不应该只针对一个人。
