固氮

Nitrogenase activity of nitrogen-fixing bacteria was measured by acetylene reduction assay combined with gas chromatography.

运用乙炔还原法测定了固氮细菌的固氮酶活性，通过测定菌落周围产生的透明圈和混浊圈大小对磷细菌的溶磷活性进行比较，采用火焰分光光度计测定了钾细菌的解钾活性。

同时从根本上改变合成氨生产的方法──生物固氮可望在21世纪取得突破性进展，并对合成氨的发展产生深远的影响。

The Complaint alleges that the Company failed to disclose and misrepresented the following material adverse facts which were known to defendants or recklessly disregarded by them:(1) that Micron engaged in illegal anti-competitive behavior to suppress and eliminate competition by fixing the prices of DRAM sold to OEMs in violation of Section 1 of the Sherman Antitrust Act;(2) that Micron's financial results throughout the Class Period were materially inflated as a direct result of the price- fixing conspiracy due to the Company's illegal behavior of price-fixing; and (3) that the Company's financial projections during the Class Period lacked a reasonable basis because they were issued while the Company involved itself in an illegal price-fixing scheme.

投诉指称该公司没有透露和歪曲了下重大不利的事实，被称为被告人或罔顾实情地无视他们：（ 1 ）微米，进行非法的反竞争行为的制止和消除竞争，固定价格的DRAM出售给OEM商在违反第1款的谢尔曼反托拉斯法；（ 2 ）微米的财务业绩在整个工人阶级期间重大膨胀作为一个直接结果，价格操纵的阴谋，由於该公司的违法违规行为的价格固氮；及（ 3 ）表示，该公司的财务预测，在一流的时期，缺乏合理的据，因为它们发出的同时，该公司所涉及的本身在一个非法操纵价格的计。

The one grain hereditary kidney bean and the red kidney bean planter output were quite high, but the nitrogen fixation quantities quite were low.

一粒传和红芸豆两年种植产量虽然比较高，但固氮量都比较低。

Research areas include biological nitrogen fixation in sustainable production, nutritional value of clover and grass, plant pathogens and overwintering problems, feeding hygiene etc.

研究领域包括可持续生？？？？的生物固氮作用、苜蓿和草的营养价值、植物病原体和越冬问题以及饲养卫生学等。

The research aimed to probe into the nitrogenfixationand absorption of different absorbents to soil.

探究不同吸附剂对土壤的固氮吸附作用。

Makes the decency coal, the pearlite and the vermiculite carries on between the root nodulebacteria and the alfalfa variety match as the matrix, alfalfas nitrogen fixation effect and thegrowing trend is higher than other two kind of matrix, the decency coal may first take the highlyeffective strain screens matrix.

以风化煤为基质进行根瘤菌与苜蓿品种之间的亲和性的匹配试验中，苜蓿的固氮效果和长势均高于珍珠岩和蛭石这两种基质。因此，风化煤可优先作为高效菌株筛选的基质。
