空间性

In this method, a novel saliency model is proposed to distinguish the salient target from background, and the eigenspace model is invoked to adapt target appearance changes.

该算法采用两个观测模型，首先提出了一种可以区分目标和背景的显著性模型，并调用特征空间模型来适应外观变化。

Based on the models, we elucidated the distribution of the stericfield, the hydrophobic field, the electrostatic field, the hydrogen bond acceptor andhydrogen bond donor, which contribute to the activity.

通过对CoMFA和CoMSIA模型的分析，确定了抑制剂上对活性有利的立体大基团、疏水性结构、电性基团以及氢键供受体等在靶酶活性结合部位的空间分布情况。

The heterologous protein fragments are so-called CTL epitope, which is the linear fragment or the space conformation structure recognized specifically by immune cell and plays a key role in CTLs activation. It is the elementary event of inducing immune responses and it decides CTL specific cytotoxic effects, therefore, selection of antigen epitope makes the pivotal step to identification of specific antibodies.

抗原肽是抗原中能被免疫细胞特异性识别的线性片段或空间构象性结构，是引起免疫应答和免疫反应的基本单位，在机体免疫中发挥关键的作用，抗原表位的选择也是能否获得特异性抗体的关键。

The existence of weak solution for quasilinear elliptic system in the whole space is studied.

讨论了在全空间上拟线性椭圆型方程组的非平凡解的存在性。

Finally, we discuss that the combination of conforming quadrilateral Q\ element and nonconforming quasi-Wilson element on anisotropic meshes. The error estimates of the energy norm and L~2-norm are obtained, which are the same as those of the traditional methods.

最后，本文研究了逼近空间取为协调的四边形Q_1元和非协调类Wilson元的情况，同样在剖分网格不满足正则性条件下，得到了与传统方法相同的能量模和L~2模误差估计。

This paper starts with the feature of RTEMS and an analysis of the space environment.

1引言在空间环境中运行的系统，实时性和可靠性是其两大需求[1]。

At first, it analyses the visibility processing of complex scene, including: spatial partition technology BSP, quadtree, octree and equational octree which can optimize scene, category of quick visibility estimation algorithm in the 3D scene, portal which can accelerate rendering, level of detail and mesh simplification based on quadric error metrics used to simply models in 3D scene.

首先分析了复杂场景的可视化处理，包括优化场景渲染的空间剖分技术：BSP树、四叉树、八叉树、均分八叉树；其次是三维场景快速可见性判断算法的分类，可加速渲染的入口技术；最后是用于三维场景中模型简化的两个算法：层次细节模型简化技术和基于视点的二次误差度量网格简化。

In chapter 4, According to the theory of scalar diffraction, firstly, the equipollence of spatial distribution of the plane-wave interferential field and parallel projective sine grating is discussed.

在第四章，根据标量衍射理论，首先讨论了两平面波干涉场的空间分布与平行投影正弦光栅的等价性。

In the negative and interrogative forms, of course, this is identical to the non-emphatic forms.

。但是，在否定句或疑问句里，这种带有"do"的方法表达的效果却没有什么强调的意思。
