Therefore,we have a deep realization about the properties of a subclass of univalent functions.

由此，我们对单叶函数一些子族的性质便有了一个全新的认识。

Stipules small, intrapetiolarly united, deciduous; leaf blade simple, margin generally serrate, rarely entire; secondary veins curved upward, especially near margin, not joining in a submarginal vein.

球兰几种球兰属的常青爬藤或灌木，从印度及中国南部至澳大利亚均为其产地，生有对生单叶及腋生的伞型花序

The research on the inner radius of univalence attract many peoples attention. Galvis , Lehto , Lehtinen, Miller - VanWieren obtained many important results.

关于单叶性内径的研究一直十分活跃，Galvis， Lehto， Lehtinen， Miller-VanWieren得到了一系列的结果。

This study reports the successful management of two cases with monolobar Caroli's disease within a family by partial hepatic resection.

我们提出同一家族内出现两个肝脏单叶性卡罗里氏病的案例，在接受部分肝脏切除手术后得到满意的成果。

Leaves simple, alternate, sometimes fascicled on short branchlets, conduplicate when young; petiole usually with 2 nectaries or sometimes nectaries at base of leaf blade margin; leaf blade margin often serrate.

有托叶。单叶，交替，有时由短开出的簇生小枝，幼时；叶柄通常具2蜜腺或有时蜜腺在基部的叶片边缘；叶片边缘通常有锯齿。

Leaves simple, stipulate, venation craspedodromous, margin serrate and lobed or partite, rarely entire.

单叶，具托叶，脉序craspedodromous，分裂的边缘有锯齿和浅裂的或，很少全缘。

Leaves simple; petiole 5-15 mm; leaf blade adaxially dark green and nitid, obovate, 6-11 × 3-7 cm, papery, abaxially sparsely pubescent, crinite in axils of lateral veins, adaxially sometimes pubescent on midvein, lateral veins 8-15 pairs, straight or not, branched far away from margin, terminal veins running into teeth, attenuate from middle to base, upper margin undulate-serrulate, apex rounded or subtruncate, tip shortly acute. Panicle terminal, 9-30 × 10-20 cm, 4 × branched, pubescent.

单叶 叶柄5-15毫米；叶片正面深绿色和有光泽，倒卵形， 6-11 * 3-7 厘米，纸质，背面稀疏短柔毛，具长软毛的在侧脉腋处，在中脉上正面有时短柔毛，侧脉8-15 对，直与否，远离边缘的分枝，圆锥花序顶生， 9-30 * 10-20 厘米，4回分枝，短柔毛。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
