立体模型

Systematic investigations were made on relationship between nuclear magnetic resonance of chemical shifts of 291 phosphines and their molecular structure parameters of phosphorus atoms, such as ionicity index and stereoscopic effect parameters ε(subscript i.

采用离子性指数、立体效应参数ε(下标 i对291个膦化合物中磷原子进行结构表征，并与其核磁共振磷谱(31P NMR)建立定量结构波谱关系模型。

Objet's machines can produce not only solid things out of plastic-type materials, but complex ones with moving parts too, such as a working model of a bicycle chain or a small gearbox.

Objet Geometries不但可以制造塑料的立体物品，还能制造有活动零件的复杂产品，如自行车链或小变速箱的可用模型。

The acute intracranial hemorrhage model of rats was made by means of stero-orientation and microinjecting self-blood,and at the same time,sixty patients with acute intracranial hemorrhage were randomly selected to observe the changes of PAG in the blood.

利用脑立体定位、微量注射自体血法复制大鼠脑出血模型；同时，随机选60例急性脑出血病例，观察还元注射液治疗后血中PAG的变化。

Epipolar geometry constraint is calculated by nonlinear error propagation at initial time to accelerate the speed of stereo matching; global and local methods are integrated to extract foreground objects precisely; and only pixels on objects' contour are reprojected into 3D space to fasten the depth calculation process.

使用视觉计算实现视频增强现实遮挡处理，用非线性误差扩散模型提高了对极几何的求解精度；将全局和局部高斯核相结合，提高并加快了物体前景轮廓线的提取精度和速度；仅用轮廓线上的点进行立体匹配的方法加快了真实物体深度反求的速度。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.

气候直方图是将所收集的降水量测定值，分为几个相等的区间作为横轴，并将各区间内所测定值依所出现的次数累积而成的面积，用柱子排起来的图形，也叫做柱状图。
