中文翻译成英文
C100~C60在发酵过程中均出现两个产气高峰,第一个产气高峰均在实验第2d,第二个产气高峰分别在实验第10d、12d和12d,且混合物中玉米秸比例越高乙酸峰值越大;C40在实验前期乙酸含量不断降低,8d后缓慢增加,到12d时达最大,之后缓慢降低;C20和C0发酵过程中乙酸含量不断降低。到实验结束时,各处理乙酸含量趋近,均在160.00 mg•L-1左右。从图4(b)可以看出,除C0外,各处理的丙酸含量在实验过程中均出现两个高峰,分别为第2d和第10d,第2个丙酸含量的峰值明显较第一个大,且混合物中玉米秸比例越高峰值越大。玉米秸与蚓粪混合发酵提高了系统中丙酸的含量。C0在发酵过程中不断降低。26d后系统中已检测不出丙酸。丁酸的变化规律与丙酸相同。混合发酵提高了系统中丁酸的含量,增强了玉米秸的产气潜力。30d后丁酸已不能检出。TVFAs的变化与丙酸和丁酸的变化相似,混合物中玉米秸比例越高TVFAs含量越高。由于C100和C80中玉米秸的负荷不同,由这两个处理TVFAs含量的变化可以看出,混合发酵明显促进了玉米秸中有机物的水解溶出,提高了TVFAs含量,从而提高了产气潜力,这与产气的结果一致(见图2)。

C100 ~ C60 during fermentation are two gas peak, the first summit in production, the second experiment first 2d production peak in the experiment were 12d and 12d 10d first, and YuMiJie mixture ratio is higher acetic peaks, In the experiment the content of C40 acid decreases, 8d 12d to increase slowly, after a while, after maximum slow down, C20 C0 and fermentation process of acetic acid content decreases. Until the end, each with acetic acid content, in reaching 160.00 mg, L - 1. In figure 4 (b) can see, in addition to the outside, the processing C0 propionic acid content in the experimental process are two peak, respectively, and the first 2d 10d first 2 propionic acid content than the first peak, YuMiJie mixture ratio and the peak values. YuMiJie and ct improved mixed fermentation dung in the system of propionic acid content. C0 during fermentation. After the system has been 26d undetectable propionic acid. The change rule and butyric acid propionic acid. To improve the system of mixed fermentation of butyric acid content, enhanced the production YuMiJie potential. After already cannot 30d butyric acid. TVFAs change and change of propionic acid and butyric acid mixture ratio, the higher YuMiJie TVFAs content is higher. Because of the C80 C100 and YuMiJie load of the two different TVFAs treatment can be seen, the content of the mixed fermentation of the YuMiJie significantly promote the hydrolysis of dissolving organic matter content, improving the TVFAs, thereby improving the gas with gas, the potential of identical results (see chart 2).

C100 ~ C60 in the fermentation process in both the two gas production peak, the first peak of gas production in the experimental section 2d, the second peak of gas production in the experimental section 10d, 12d and 12d, and a mixture of the higher proportion of corn stalks the greater the acid peak; C40 early in the experiment to reduce acid content, 8d, after a slow increase up to the 12d largest, followed by slowly; C20 and C0 in the fermentation process to lower acid content. To the end of the experiment, the acid content of each treatment approach, are 160.00 mg • L-1 about. Figure 4 (b) can be seen, with the exception of C0, each dealing with the acid content in the experiment were two peaks, respectively, for the first 2d and 10d, the first of the two propionic acid content was significantly less than the first peak large, and a mixture of corn stalks in the greater proportion of the higher peak. Earthworm manure and corn stalks mixed fermentation system to improve the content of propionic acid. C0 continuous fermentation process in the lower. 26d after the system has detected no acid. Butyric acid and propionic acid of the same changes. Mixed fermentation of butyric acid to enhance the system's content and enhance the corn stalks of the potential gas production. 30d can not be detected after the acid has been. TVFAs changes and changes in acid and butyric acid is similar to a mixture of corn stalks in the higher proportion of the higher content of TVFAs. C100 and C80 as a result of corn stalks in the load varies from TVFAs content to deal with these two changes can be seen clearly mixed fermentation of corn stalks to promote the hydrolysis of organic matter dissolution, TVFAs content increased, thereby increasing the potential gas production, which with the results of gas production line (see Figure 2).

The C100 ~ C60 is in the process of ferment in all appear 2 to produce spirit high peak, the first produce spirit high peak all at the experiment 2 ds, the second produce spirit high peak distinguish at experiment 10 ds, 12 ds and 12 ds, and the corn Ji comparison more high acetic acid Feng in the mixture be worth more big;The C40 expects the acetic acid content to continuously lower before test, slow-moving increment after the 8 ds, arrive 12 ds reach biggest, slow-moving lower after;C20 and C0 ferment in the middle of the process the acetic acid content continuously lowers.Everywhere manage an acetic acid content to tend while arriving experiment be over near, all at 160.00 mgs?The L-1 is or so.From the figure 4(b) can see, in addition to C0, the C sour content of each processing is in the process of test in all appear two high peaks, is a 2 ds respectively 10 ds and, the 2nd Feng of content with sour C be worth obviously theer first big, and the corn Ji in the mixture's comparison more the high peak be worth more big.Corn Ji and Yin muck mixture fermented to raise the C sour content in the system.The C0 is in the process of ferment in continuously lower.Have already coulded not examine C in the system after the 26 ds sour.The D sour variety regulation and C are sour and same.The mixture fermented to raise the D sour content in the system and strengthenned the produce of corn Ji spirit potential.D's ising sour has already can't check after the 30 ds.TVFAs variety and C are sour and the D sour variety likeness, corn Ji's comparison in the mixture the more high TVFAs content be more high.Because of the burden dissimilarity of corn Ji in C100 and C80 is can see by these two varieties which handle a TVFAs content, the mixture fermented to obviously help the water solutions of organic matter in the corn Ji to dissolve, raised a TVFAs content, raised to produce spirit potential thus, this with produce the results of spirit consistently.(see figure 2)
