形成边缘

As such, it was situated on the sheer drop-off that marked the edge of the Basin-the remains of a major impact crater that had gouged a magnificent long bowl out of the surface.

正因为如此，它坐落在盆地边缘的峭壁上——所谓盆地，就是冲击火山口遗迹在地表形成的一道壮观的狭长凹地。

An optimal heat transfer criterion was proposed, which means that the optimal heat transfer appears when the region outside the impellent thin spray film inscribes in the square heated surface.Based on the H criterion aforementioned, two DANFOSS nozzles of the three with inclined spraying angles were used to experimentally study the temperature distribution in the heated surface.

应用不同DANFOSS喷嘴对水平热源进行垂直喷射，在变换喷嘴距热源表面高度的前提下，研究最优换热性能出现在何种情况，得出H准则：当喷雾形成的液膜的圆形外推区域正好与热源边缘相切时，系统换热性能达到最佳。

In the period of Mesozoic-Palaeozoic, Caledonian events and the evolution of Hercynian -early indo-Chinese cycle are experienced in two-phase marine passive continental margin and Craton basin in the lower and middle Yangtze Region, by which stable enormous thick Mesozoic-Palaeozoic deposites are induced, six sets of source rocks are produced, it has a strong capacity of hydrocarbon generation.

通过构造演化特征分析了海相烃源岩的发育，中、下扬子区中－古生代经历了加里东和海西－早印支旋回两个阶段的海相被动大陆边缘和克拉通盆地演化，形成了岩性稳定的巨厚中－古生界，发育了6套烃源岩，具有较强的生烃能力。

Actuarial mathematics is a marginal science between applied mathematics and insurance study field.

保险数学是应用数学研究领域和金融保险研究领域这两者之间形成的一门边缘学科。

Actuarial science applies mathematical methods in insurance and is a science between applied mathematics and insurance. Bonus-malus system of automobile insurance is an important topic in actuarial science. Markov chain, Bayes theory, the theory of delay differential equation and dynamic programming are used to study BMS, especially optimal BMS, of automobile third-party liability insurance in this dissertation, which is organized as follows:First, we study the properties of Chinese present BMS.

精算学是将数学方法应用于金融保险所形成的一套理论体系，是应用数学研究领域和金融保险研究领域这两者之间的一个边缘学科，汽车保险奖惩系统是现代精算学中的一个重要研究课题，本文主要用马尔可夫链、贝叶斯理论、时滞微分方程理论与动态规划等研究汽车第三者责任保险奖惩系统，特别是最优奖惩系统。

Herbs , perennial, pubescent, with dark glands present on petals, sepals and sometimes on leaf apex, but not on anthers or forming intramarginal row on leaves. Stems rooting.

草本 ，多年生草本短柔毛，在花瓣上的具深色的腺体宿存，萼片和有时在叶先端上，但不是在花药或上在叶上形成近边缘内的排。

Herbs, perennial, glabrous to papillose , with dark glands present on petals, usually on sepals and sometimes on leaf apex , but not forming intramarginal row on leaves. Stems not rooting.

多年生草本，无毛到具小乳突，在花瓣上的具深色的腺体宿存，通常在萼片上和有时在叶先端上，但不是在叶上形成近边缘内的排。

Leaves with petiole 0.5-2 mm; blade narrowly triangular-lanceolate, 2.5-5.8 × 0.7-2.3 cm, thickly papery, abaxially ± densely glaucous; laminar glands long to short streaks; abaxial glands rather sparse; main lateral veins 2- or 3-paired, all branches clearly visible and forming undulating intramarginal vein, tertiary reticulation nearly invisible; base cuneate, apex acute to subacute.

叶具叶柄0.5-2毫米；叶片狭三角形披针形， 2.5-5.8 * 0.7-2.3 厘米，厚纸质，背面多少密被白霜；片状的腺长到短条纹；背面的腺体相当稀；主要侧脉2-或3对，全部的分枝明显可见的并且形成波状近边缘内脉，近看不见的第三级网脉；基部楔形，先端锐尖到近尖。

Lateral surface of the module support forms a protruding strengthened edge for locking the bolt in the front frame.

模块支架的外侧面形成突起的加固边缘，上述Pem Nut中锁紧固定在上述前框上的螺栓。

Tracing the journey of their works from marginality to centerpiece in literary history, this paper holds that ideology, poetics and patron play a vital role in the way to canon, which is a universal law applicable to different national literatures.

本文旨在考察他们的作品从边缘走向中心的过程中，意识形态、主流诗学和赞助人所起的作用，以管窥文学经典化形成中的共性。

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。
