| 2. | Cellular organelles of eukaryotes have a distinctive spatial distribution and communicate through an elaborate system of vesicular - tubular transport
真核细胞中细胞器在空间上分布不同，各细胞器之间通过复杂的囊泡运输和微管系统进行物质交换和信息传递。 |
| 3. | A system can remain in existence and keep its youth only by way of exchanging with outside systems , and keeps pace with the development of the outside environments
一个系统只有在不断和外界进行物质交换和交流，并在发展的过程中进行调适，才能保持自己的青春活力。 |
| 4. | Contact binary : in these binary stars , components are too close together that they have material exchange . the mutual gravity may also deform the stars and glue them together
：这种双星系统，子星间的距离十分接近，强大的引力不单只把恒星拉扯至变形，更造成子星间出现物质交换，把两星连接起来。 |
| 5. | Human placenta is a unique organ that exchanges substance between fetal and maternal blood . it provides a number of functions to ensure that developing fetal is maintained in optimal conditions for the rapid events of gestation
胎盘是胎儿和母体进行物质交换的场所，它为胎儿提供氧和营养物质，将胎儿体内代谢产生的废物排出体外，从而保证胎儿的正常发育。 |
| 6. | Result : the layers of tissue engineeringed vascular model were combined tightly . hvec , vsmc and fibroblast can secrete extracelluar matrix ( ecm ) and interchange substance , resemblin physiological functions
构建后的血管模型，层与层结合紧密，内皮细胞、平滑肌细胞及成纤维细胞分泌细胞外基质，相互进行物质交换，类似于生理条3第四军医大学硕士学位论文件。 |
| 7. | Weapons testing with high - speed projectiles helped prove that material exchange between the planets is not so limited as had once been thought : in fact , some 500 kilograms of rock from mars are estimated to land on the earth each year
武器实验中发射的高速射弹也有助于证明行星际的物质交换并不像以前认为的那样有限：事实上，每年约有500公斤火星岩石溅落到地球上。 |
| 8. | These interactions may also serve as important ways for lithosphere recycling and mass exchange between the shallow and deep parts of the earth , which could significantly affect deep mantle convection and surface tectonic processes
这种相互作用被认为是稳定克拉通岩石圈遭受改造甚至破坏的深部机制，同时还是地球深、浅部物质交换的重要方式，因而显著影响着地球深部的对流和地表的构造过程。 |
