生物降解资料的降解功能,对生物降解资料的降解功能的测验目前还没有制订一致的规范,可采用包含被美国资料试验规范(ASTM)采用或预备采用的办法作为规范的办法,通过生物化学和微生物的试验手法来点评的主要办法有下列几种。

The degradation function of biodegradable data and the test of the degradation function of biodegradable data have not yet formulated a uniform standard. The methods adopted or prepared by ASTM can be used as the standard method. The main methods for evaluating the degradation function of biodegradable data by biochemical and microbial test methods are as follows.
土埋法,土埋法有室外土埋法和室内土埋法两种,其微生物源主要是土壤中的微生物群,经必定时刻后,取出试样测定其失重、机械功能改变,或用电子显微镜断定其被土壤中微生物侵袭的状况。
There are two kinds of burial methods: outdoor burial method and indoor burial method. Their microbial sources are mainly microbial groups in the soil. After a certain time, the samples are taken out to determine their weight loss, mechanical function changes, or to determine their invasion by microorganisms in the soil by electronic microscopy.
长处是能反映出自然环境条件下的生物分化功能;缺点是试验周期长,试验成果因土质不同而不同,重复性差。陪替氏培育器定量法在容器中参加试验样品和营养琼脂,接种微生物进行培育,经必定时刻后,剖析试样的失重状况以及某些物理改变或化学改变。
The advantage is that it can reflect the biological differentiation function under natural environment conditions, while the disadvantage is that the test cycle is long, the test results vary with soil quality, and the repeatability is poor. Quantitative method of Vettel incubator participates in the test sample and nutrient agar in the container, inoculates microorganisms for cultivation, after a certain time, analyses the weight loss of the sample and some physical or chemical changes.
长处是可快速降解,在短时刻内取得试验成果,重复性好,定量性好;缺点是不能反映自然界中的实际状况。酶剖析法在容器中参加缓冲液和试验样品,让酶效果必定的时刻后,剖析试样的失重状况,目测霉菌的成长状况,显微镜剖析试样物理功能或化学功能的改变。
The advantages are fast degradation, good repeatability and good quantification. The disadvantage is that it can not reflect the actual situation in nature. Enzyme dissection is used to participate in buffer solution and test sample in container. When the effect of enzyme is certain, the weight loss of sample is analyzed, the growth of mould is visualized, and the changes of physical or chemical functions of sample are analyzed under microscope.
长处是试验周期短,重复性好,定量性好;缺点是不能反映自然界中的实际状况。放射性C14示踪法用C14标记聚合物产品,在微生物的效果下发生CO2,用碱性溶液吸收。
The advantages are short test cycle, good repeatability and good quantification, while the disadvantages are that it can not reflect the actual situation in nature. Radioactive C14 tracer uses C14 to label polymer products. CO2 occurs under the effect of microorganism and is absorbed by alkaline solution.
用滴定法测出CO2总量,再用放射性衰减率法测定C14的CO2量,用C14的CO2占发生的CO2的百分数表示微生物侵蚀的程度。长处是试验成果可信、清晰。生物降解功能的测验能够检测样品生物降解功能的优劣。
The total amount of CO2 was measured by titration, and then the amount of CO2 in C14 was measured by radioactivity attenuation rate. The percentage of CO2 in C14 was used to indicate the degree of microbial erosion. The advantage is that the test results are credible and clear. The test of biodegradability can test the biodegradability of samples.
