Consistent with this, oral teeth are proposed to arise exclusively from ectoderm, contributing to tooth enamel epithelium, and from neural crest derived mesenchyme, contributing to dentin and pulp.

脊椎动物的口腔发育被认为是始于外胚层的内陷，因此牙齿的发育被认为是外胚层和神经嵴来源的间充质。

If the design or electrotype of the electrophoresis coating line is unstable or its manufacturing quality lower than expected, quality problems arise which are not solvable by means of management intervention.

电泳涂装设备是投资较大，技术要求较高，结构复杂的涂装设备，如果电泳涂装线设计或选型不当或制造质量不佳，造成的电泳涂装质量问题，靠管理是克服不了的。

This paper is devoted to solving linear saddle point problems, Specifically, We consider nonsymmetric systems, written as usual in block form, where the upper left block is an invertible linear operator with positive definite symmetric part. Such saddle point problems arise, for example, in certain finite element and finite difference discretizations of NavierStokes equations, Oseen equations, and mixed finite element discretization of second order convection-diffusion problems.

For a monotone twist map the well-known Birkhoff fixed point theoremsays that the circles with rational rotation number will break up whence a finitenumber of pairs of periodic points arise,half of which are elliptic and the othershyperbolic.Moreover,around each elliptic periodic point a few of new invariantcurves will appear and make a picture of phase space with a self-similar structure.Again one may ask is there a similar picture for higher dimensional Hamiltoniansystems?

对于单调扭转映射，著名的Birkhoff不动点定理指出，在通有情况下旋转数为有理数的不变曲线一般会破裂，在原来的不变曲线附近会产生有限多对周期点，其中一半是双曲的，一半是椭圆的，而在椭圆型周期点的周围又会产生一圈圈的不变曲线，使得椭圆周期点附近的动力学行为和整个相空间的动力学行为十分相象，换句话说，整个相空间具有无限嵌套的自相似结构，自然又产生了一个问题：对于自由度数目大于2的高维哈密顿系统，其相空间是否有类似的图象？

At present, with China's ongoing social transformation some new problems arise, and to solve these problems we must further emancipate the mind.

当前，中国正在进行社会转型，出现了一些新的问题，要解决这些问题只有进一步解放思想。

These epithelial elements arise embryologically from foregut endoderm in the process of bronchial tubular growth.

这些表皮细胞在胚胎学上把源于支气管生长过程中的前内脏叫内胚层。

Thus we find that they, too, arise from an epithelium.

因此我们发现，它们也起源于上皮组织。

Histologically, 95% of ovarian cancers arise from the ovarian surface epithelium.

组织学研究表明95%的卵巢癌起源于卵巢表面上皮。

Also there is much difference between the obtained metastable phase diagram at 35 ℃ and the metastable phase diagram at 25 ℃. The crystallization regions of schoenite(K2SO4*MgSO4*6H2O) and epsomite disappear and arise the crystallization regions of leonite and kainite.

所得35 ℃介稳相图与25 ℃介稳相图区别很大：软钾镁矾和七水硫酸镁结晶区域消失，同时出现了钾镁矾和钾盐镁矾的结晶区域。

Moreover, the error source and the error which may arise of control system are analyzed.

此外，本文还对系统可能产生的误差源及误差进行了分析。

But this is impossible, as long as it is engaging in a market economy, there are risks in any operation.

但是，这是不可能的，只要是搞市场经济，是有风险的任何行动。

We're on the same wavelength.

我们是同道中人。
