固氮的

Discussed the subject on the rich symbiont germplasm resource in China and on further research being necessary to exploitation and utilization of the benificial germplasm.

文摘：针对我国主要豆科作物大豆和花生的研究成果，并结合本身研究工作内容，(1)总结了与宿主共生的根瘤菌生物学多样性，包括大、小样本的土著根瘤菌群体数量、分离频率、类型与分布及其菌株―宿主共生混交性与亲和性；(2)评述了根瘤菌―宿主植物共生体双边固氮改良，包括优良菌株的选育、宿主品种资源共生特性的评价与利用及特异性状的选择；(3)讨论了我国这一类共生体资源的丰富性以及有必要进一步加大力度研究有益资源的开发和利用的问题。

However,the soil moisture content at soil depths of 45 cm and 60 cm in the areas with microbiotic crusts is much lower than that in the areas without microbiotic crusts(LSD-test,p.05),which reveals that the microbiotic crusts have high capability of maintaining topsoil moisture.

在世界干旱区的大量研究表明，作为荒漠生态系统的重要成分，生物结皮的形成能够增强土壤抗风蚀及水蚀的能力〔3~8〕、增强其周围维管植物的养分循环〔9~11〕、通过生物固氮提供丰富的氮源〔12〕、促进种子库的建立和生物多样性等。

Roger and co-authors （1993） suggest that in some instances inoculation may be useful, particularly since the inocula produced with high levels of P may have an advantage over P-limited indigenous strains; however, they suggest management practices that enhance the proliferation of native cyanobacteria to increase the N-fixing potential of these organisms.

Roger 和他的合作者们（1993）认为在某些时候接种剂是有用的，特别是高磷条件下培养的菌种对于低磷土著品系来说有一定的优势；但他们建议采用增强固有兰细菌生长繁殖的管理措施以提高这些微生物的固氮能力。

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。

One such novel idea is that of inserting into the chromosomes of plants discrete genes that are not a part of the plants' natural constit ution:specifically,the idea of inserting into nonleguminous plants the genes,if they can be identified and isolated,that fit the leguminous plant s to be hosts for nitrogen-fixing bacteria.

复杂修饰+插入+省略+倒装）这其中的一个新颖思想就是，在植物的染色体内注入并非是该植物自然构造一个部分的那些不相关联的因基：具体而言，这一思想是，在非豆科植物内注入这样一些基因，倘若这些基因可被辨识出来并被分离开来，而这些基因业已使豆科植物宜于充当那些具备固氮作用的细菌的寄主。
