The paper tries to solve this by introducing spatial dimension, indexes of spatial aggregations index which point to the record set of spatial aggregation, as well as spatial constrains sets, into the traditional MDM, to construct spatial MDM and spatial data cube.

文中尝试在传统多维数据模型中引入空间维度，在度量中引入指向空间聚合结果的空间聚合索引，并引入空间算子集合，从而构造出空间多维数据模型和空间立方体。

Tuning the intermolecular interaction of such kind of tetrapyrrole derivatives can be easily reached by introducing functional groups ( actually additional non-covalent interactions) onto the peripheral positions of porphyrin ring.

所以，调控卟啉类化合物及其衍生物的分子间弱作用可以很容易地通过在卟啉环或其衍生物的外围引入不同的官能团（实际上是通过引入官能团来引入非共价弱作用）来实现。

Researchers have employed multi-modal learning, multi-task learning and transfer learning methods to bring the image associated text information into image classification tasks.

已有研究者使用多模态学习、多任务学习和迁移学习等方法，将图像相关的文本信息引入图像分类任务中，实验表明引入与图像相关的文本信息对图像分类性能有所提升。
