According to the experiment results of degradation in field, degradation mechanism of the biodegradable mulch film can include four stages: the first, the material surface appeared deficiency while the surface area and interstice increased of material in the action of natural environment and microorganism; the second, along with the surface area and interstice of material increased and the gap strengthened, the chemical chain of the high polymer's principal chain broke as a result of the hydrolysis or the enzymatic effect in the action of hydration, causing the molecular weight and mechanics function descended; the third, the molecular of high polymer split the low polymer after its physical mechanical function descended, the material decomposed the fragments, the mass defect intensified; the fourth, the low polymer of fragments form in the natural environment, the microorganism, the biological enzyme became the smaller fragments, thus absorbed by the phagocytes, or further turn into CO2 and H2O due to hydrolysis.
根据田间降解试验结果推测,生物全降解地膜的降解机理可能包括四个阶段:第一,在自然环境、微生物作用下,材料表面出现缺陷,同时表面积增大、空隙增多;第二,随着材料表面积的增大、空隙的增多,吸水性增强,在自水合作用下,高聚物主链由于水解或酶解而使化学链断裂,导致分子量和力学性能下降;第三,在其物理机械性能下降后,高聚物分子链断裂为低聚物分子,材料裂解为碎片状,质量损失加剧;第四,碎片状低聚物在自然环境、微生物、生物酶作用下进一步水解变成尺寸更小的碎片,从而被吞噬细胞吸收,或进一步水解,生成CO2和H2O。

An experiment is conducted to understand the effect of high molecular polymer fluid on the flow measurement using rotameter. In the experiment, the rotameters, which are composed of different floating elements with different shapes and materials in measuring tubes, are employed to measure the high molecular polymer fluid with viscosity from 1 MPa·s to 2 692 MPa·s. Through analyzing the impact of high molecular polymer fluid on the different rotameters, a general rule is obtained for measuring high polymer fluid using rotameter.
为了了解高分子聚合物黏性溶液对浮子流量计流量测量的影响,采用由不同材料与不同形状浮子构成的浮子流量计分别对动力黏度从1 MPa·s到2 692 MPa·s范围的高分子聚合物溶液进行流量测量,根据对不同浮子流量计受黏性影响实验的分析,获得了高分子聚合物黏性溶液对浮子流量计测量影响的规律。
