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现在还没有制订一致的规范.

The degrading function of biodegradable data and the test of the degrading function of biodegradable data have not yet formulated a consistent standard.
可采用包括被美国资料实验规范(ASTM)采用或准备采用的办法作为规范的办法,经过生物化学和微生物的实验手段来评价的主要办法有下列几种。
There are several main methods to be evaluated by biochemical and microbiological methods, including those adopted or prepared by ASTM.
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,经必定时间后,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 microorganisms in the soil. After a certain period of 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解功能;缺陷是实验周期长,实验成果因土质不同而不同,重复性差。
The advantage is that it can reflect the biological decomposition function under natural environment conditions; the defect is that the experimental period is long, the experimental results vary with soil quality, and the repeatability is poor.
陪替氏培育器定量法在容器中参加实验样品和养分琼脂,接种微生物进行培育,经必定时间后,剖析试样的失重状况以及某些物理改变或化学改变。
Quantitative method of Vettel incubator is to take part in the experiment sample and nutrient agar in the container, inoculate microorganisms for cultivation, after a certain time, analyze the weight loss of the sample and some physical or chemical changes.
长处是可快速降解,在短时间内取得实验成果,重复性好,定量性好;缺陷是不能反映自然界中的实际状况。
The advantage is that it can be degraded quickly, and experimental results can be obtained in a short time. It has good repeatability and good quantification. The disadvantage is that it can not reflect the actual situation in nature.
酶剖析法在容器中参加缓冲液和实验样品,让酶效果必定的时间后,剖析试样的失重状况,目测霉菌的生长状况,显微镜剖析试样物理功能或化学功能的改变。
Enzyme dissection method takes part in buffer solution and experimental sample in container. After the effect of enzyme is certain for a certain time, the weight loss of sample is analyzed, the growth of mould is observed visually, and the changes of physical or chemical functions of sample are analyzed under microscope.
长处是实验周期短,重复性好,定量性好;缺陷是不能反映自然界中的实际状况。
The advantage is that the experiment cycle is short, the repeatability is good, and the quantity is good. The defect is that it can not reflect the actual situation in nature.
放射性C14示踪法用C14符号聚合物产品,在微生物的效果下发生CO2,用碱性溶液吸收,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。
Radioactive C14 tracer method uses C14 symbolic polymer products to produce CO2 under the effect of microorganisms, absorbs CO2 in alkaline solution, measures total CO2 by titration, and then measures CO2 content of C14 by radioactivity attenuation rate. The percentage of CO2 in C14 is used to indicate the degree of microbial erosion.
长处是实验成果可靠、清晰。生物降解功能的测验可以检测样品生物降解功能的优劣。
The advantage is that the experimental results are reliable and clear. The biodegradability of samples can be tested by the biodegradability test.
