  “rice hull ash”译为未确定词的双语例句
     Considered the substrates cost, the benefit of 4L per plant were higher than 5L per plant with 370 yuan per 667m2. In order to reduce cost and improve benefits, when rice hull ash and sawdust were used as substrates, 4L per plant, i.e. 8m3 per 667m2, should be used.
     但在除去基质成本时,基质用量4L的黄瓜效益比5L的高370元/667m2。 因此,为了降低生产成本,提高经济效益,黄瓜采用炭化稻壳和木屑混合基质栽培时,每株基质用量可采用4L,即每667m2的用量为8m3。

Seven kinds of clay powder: attapulgite, halloysite, bentonite, diatomite, kaolin, talc and rice-hull ash were soaked in the protectant Solutions: malathion, fenitrothion and pirimiphos methyl. After drying, the clay powders mixted with the wheat. The wheat which was treated was stored for 30 days at30℃. The retaintivity of the clay powders to the protectants Was determined respectively. At the same time, the three protectant solutions were dripped in and mixed with the wheat. Then the seven...

Seven kinds of clay powder: attapulgite, halloysite, bentonite, diatomite, kaolin, talc and rice-hull ash were soaked in the protectant Solutions: malathion, fenitrothion and pirimiphos methyl. After drying, the clay powders mixted with the wheat. The wheat which was treated was stored for 30 days at30℃. The retaintivity of the clay powders to the protectants Was determined respectively. At the same time, the three protectant solutions were dripped in and mixed with the wheat. Then the seven kinds of clay powder were added to the wheat at the different Storage period. After a given storage period, the absorption of the 7 clay powders to the protectants was determined respectively. The result showed the retentivity and absorption of attapulgite and bentonite were higher than those of other clays. The retentivity and absorption of talc and rice-hull ash were poor. It found that there was a certain distribution rule of protectant between the clay powders and the wheat, the distribution rule was different from the different protectants and clay powders, and the time which protectants reached the distribution equilibrium between the clay powders and the wheat was also different. The effect of decline rate of attapulgite and bentonite on the protectants in wheat was determined. The attapulgite put off the dicline of the 3 protectants obviously.

七种粘土粉末:硅镁土、埃洛石粉、膨润土、硅藻土、高岭土,滑石粉和稻壳灰被三种储粮保护剂:马拉硫磷、杀螟松和虫螨磷溶液浸泡.干燥后施于小麦中,在30℃下储存30天,测定粘土粉末对保护剂的保持能力,即测定保护剂在粘土中和小麦中的分配比例.同时用三种保护剂溶液以滴入加搅拌法处理小麦,然后在不同的储藏时间加入上述七种粘土粉末,再存放一定时间,测定七种粘土从小麦中吸附(夺取)保护剂的能力.结果表明,硅镁土和膨润土无论在保持能力上,还是在吸附能力上都比其他几种粘土强.保持能力和吸附能力最差的是滑石粉和稻壳灰.实验发现储粮保护剂在粘土粉末和小麦间有一定的分配规律,不同保护剂,不同粘土粉末其分配规律不同,保护剂在粘土粉末和小麦间达到分配平衡的时间也不同.马拉硫磷在稻壳灰和小麦间达到分配平衡的时间只需要一天,虫螨磷在硅镁土和小麦间达到分配平衡需要三天,杀螟松在硅镁土和小麦间达到分配平衡需要二十八天.测定了硅镁土和膨润土对储粮保护剂在小麦中衰减率的影响,硅镁土明显地延缓三种保护剂的衰减.本研究的意义在于为储粮保护剂的应用找到一条更好的途径,应用粘土粉末作保护剂载体,它能在吸附大量保护剂之后再附着在粮食表面,局部药剂浓度高,有利杀...

This paper described the formation of SiC-coating from the reaction of rice hull ash with graphite at temperature (16b0±50)℃. It was investigated that the thinkness of SiC-coating and its density increased with holding time. The interface bonding strength and thermal shock resistance of high porosity graphite were lower than that of low porosity one, and in respect of resistance against oxidation burn-off, the low porosity graphite was superior to the high porosity one.X-ray diffraction study showed SiC-coating...
