| 1. | Clearly the principle requirement for a substance to be capable of forming a structural unit of a polymer chain is that it must be difunctional .
显然，对于能成为聚合物链结构单元的物质的基本要求是：它必须是双官能的。 |
| 2. | Folding and aggregation of polymer chains
高分子的折叠与聚集 |
| 3. | It can also be manufactured from the large polymer chains found in cereals , grasses and trees
此外，它还可以从在谷、草与树中发现的聚合物链中制造出来。 |
| 4. | Proton transport is controlled by both segmental motion of the polymer chains and hoping of protons
通过构造新模型，研究了质子数等因素对质子在质子交换膜中输送过程的影响。 |
| 5. | The length of the polymer chain is specified by the number of repeat units in the chain . this is called the degree of polymerization
聚合物链的长度可以用链中重复单元数来表示，叫做聚合度。 |
| 6. | The polymer ic effects of polylactide - garfted copolymer of - cyclodextrin , including cooperation effect , neighboring effect and polymer chain effect were discussed
总之， ?环糊精与这三种芳香族氨基酸之间的包合是多种因素协同作用的综合效果。 |

| 8. | It was found that introduction of hydrophobic monomer into polymer chain improved the response linearity and sensitivity , and the impedance of sensors decreased with longer quaternization time and shorter distance between electrode tracks
发现：疏水性单元的引入，提高了湿敏元件的响应线性度和灵敏度；季胺化时间的延长，使聚合物季胺化程度提高，湿敏元件阻抗减小；电极叉指间距增大，阻抗增大。 |
| 9. | The determination of the cloud point of pu - sio2 , pes - sio2 suspensions was obtained by titration . the results showed that the addition of si02 with a high specific surface made polymer chains adsorbed at the surface , influenced the phase behavior of suspensions , shifted the bimodal to lower nonsolvent concentrations , and the water tolerance became bad
实验证明，具有高比表面积、多孔性的sio _ 2对pu 、 pes铸膜液的相行为有较大影响，随着sio _ 2加入，双节线向聚合物-溶剂轴移动，均相区变小，分相区变大，分相时需要非溶剂的量变小，铸膜液的耐水性变差。 |
| 10. | The dispersion of mmt and the properties of composites were basically determined by the nature of organo - mmt and the polarity of the polymer chains . the intercalated nanocomposites could be explained in terms of the formation of " ladder " structure due to the excessive polar groups on the polymer chains which adhere adjacent silicate sheets
插层高分子链的极性基团含量要适宜；否则，极性基团将相邻片层“胶粘”形成稳定的“梯形”结构，导致高分子链插层受阻，易形成插层型纳米复合材料。 |
