查询词典 originate from

However, odontogenic tumors or cysts may originate from residual cells, although little is known about how HERS proliferates and disappears.

虽然对于HERS细胞的增殖及消失了解甚少，但牙源性肿瘤或囊肿可能起源于上皮剩余。

The possible reason is that doped Zr〓 ion enters the interstitial sites for its small ionic radius and no dipole complexes were formed. Monovalent ion F〓 has been reported to improve the scintillating performance greatly. Our results show that Agrand diagrams of F〓: PWO crystals obey an modified Cole-Cole equation. The crystals present similar dielectric relaxation phenomena to but have much higher activation energy than that of RE〓: PWO crystals, which originate from the 〓 dipole complexes. The co-doping of trivalent Y〓 and pentavalent ion Nb〓 does not always show a better scintillation performance than that of solely doped samples, which could be attributed to the existence of the 〓 dipole complexes, which counteract the solely doping effect.

而Zr〓由于离子半径太小，可能进入间隙位置，不形成类似的偶极缺陷；一价负离子F〓的掺入提高了晶体闪烁性能，阻抗谱测试结果表明F〓：PWO晶体Argand图符合修正的Cole—Cole方程，晶体同样表现出介电弛豫现象，并具有比RE〓：PWO晶体中高得多的弛豫激活能，可能起源于形成的〓偶极缺陷；Y〓和Nb〓双掺的PWO晶体并没有显示出两种离子单掺优点的叠加，阻抗谱测量结果表明，在双掺晶体中可能形成〓偶极缺陷，使两者掺杂作用相互抵消。

These meteors originate from a mysterious object called 3200 Phaethon.

这些流星来自一个叫3200 Phaethon的神秘物体。

These meteors originate from a mysterious object called 3200 Phaethon. It may be an asteroid or it may be a burnt-out comet.

双子座流星雨源自一个天体3200 Phaethon，它或许是一个小行星，也说不定是一颗已燃烧殆尽的彗星。

Secondly, according to the stem and leaf anatomy, leaf epidermis, pollen morphology and floral development, it is found that there are no close relations between Acorus and Typhales, especially in the aspect of floral development. In the course of floral development of A. calamus, neither bracteloe primordium nor common primordium occurs in the whole course. Early development of the flower is strongly unidirectional. Three shield carpels develop into a pistil. In Sparganium fallax, each female flower has a bracteole. The bracteole primordium and the floral primordium originate from a complex structure. A single saccate carpel develops into a pistil. In staminate flowers, petal and stamen primordia initiate spirally.

菖蒲属与香蒲目的茎叶解剖特征、叶表皮特征、花粉特征及花器官发生特点等亦存在着明显区别，特别是花器官发生特点差异尤为显著，如菖蒲属花器官发生过程中，没有苞片原基，也不存在任何形式的复合原基，花被与雄蕊原基均以单向性方式发生，雌蕊由3心皮发育而成，具有&盾状心皮&的特点等，黑三棱属则有苞片原基发生，且苞片原基与雌花原基起源于共同的复合结构，雄花的花被原基和雄蕊原基均以螺旋状方式发生，雌蕊由单心皮发育而成，未发现有2或3个心皮原基或其痕迹的现象，体现出&囊状心皮&的特点。

Cloves originate from an evergreen tree that is called "Syzygium".

来自丁香的常青树就是所谓的&赤&。

English proverbs generally originate from folk life,Bible and mythologies,literary works and other languages.

本文分析了英语谚语的来源、文化特点、修辞特点和启发教导功能。

All songs are sang live, all drums are percussed live and all dances originate from the real life.

节目中所有的歌都由演员自己唱，所有的舞都来自真实的生活，所有的鼓都是现场打奏。。。。。。

Plant hairs originate from many different trees and are sometimes seen in Papanicolaou smears during the spring and summer.

在春夏天，来源于很多不同的树木的的毛会不时的在巴氏涂片中被发现。

If the TBCs system is homogeneous, the TGO will take on relatively regular and periodical undulation. Unfortunately, in actual situation, some abnormal thick areas will be presented in TGO, which is in single-layer or multi-layer form. In SEM, it can be seen that such protrusion areas originate from TGO, and penetrate into bond coat layer gradually with the increment of oxidation time, namely, the oxidation localization phenomenon occurs.

如果体系均匀，则TGO层将表现出较规则的周期状起伏，但在实际服役过程中，TGO层经常出现单个的异常厚部位或多层的异常厚部位，在扫描电镜图上呈现出钉子状或瘤状的局部突起物，这种突起物源于氧化层，并随着高温工作时间的延长向粘结层中扩展，即发生了氧化局域化现象。

With Death guitarist Schuldiner adopting vocal duties, the band made a major impact on the scene.

随着死亡的吉他手Schuldiner接受主唱的职务，乐队在现实中树立了重要的影响。

But he could still end up breakfasting on Swiss-government issue muesli because all six are accused of nicking around 45 million pounds they should have paid to FIFA.

不过他最后仍有可能沦为瑞士政府&议事餐桌&上的一道早餐，因为这所有六个人都被指控把本应支付给国际足联的大约4500万英镑骗了个精光。
