Soybean cultivar "Ludou 4" was inoculated with the AM fungus Glomus fasciculatus, soybean cyst nematode Heterodera glycines race 4 and the AM fungus plus SCN. A number of coefficients such as mycorrhizal colonization, SCN infection rate, activities of chitinase and PAL and transcripts of the genes Chibl(Chitinase b1) and PAL5 in soybean roots were assayed.

本研究系统分析了大豆(品种：'鲁豆4')接种AM真菌Glomusfasciculatum和胞囊线虫(SCN，Heterodera glycines)4号生理小种后各处理菌根和线虫侵染率、几丁质酶和苯丙氨酸解氨酶活性及几丁质酶基因Chib1和苯丙氨酸解氨酶基因PAL5转录物的动态变化。

The stable or unstable state of the montmorillonite-water dispersion is mainly effected by the properties of montmorillonite, water, and stabilizers as well as their interactions, while the type, the structure, the properties and the concentration of the stabilizer play dominate roles. Based on the molecular designing clues, this research selected three sulfonated copolymers as the stabilizers, i.e. the sodium 2-acrylamido-2-methyl-1propane sulfonate /acrylamide /disodium itaconate terpolymer, the AMPS/AM/N-vinyl pyrrolidone terpolymer and the sodium styrenesulfonate /IA copolymer. The preparation and characterization of the sulfonated copolymers were discussed, the high-temperature stability of the montmorillonitewater dispersion was characterized with the rheology, the filtration, the particle size distribution, the electrostatic properties, and the adorption of the sulfonated copolymers onto montmorillonite particles. At the same time, a systematic mechanism of the hightemperature stabilization of the dispersion was presented.

本文构筑了分子设计的思路，选取AMPS(2-丙烯酰胺基-2-甲基丙磺酸钠)/AM/IA三元共聚物、AMPS/AM/NVP三元共聚物和SSA/IA二元共聚物等三种磺化共聚物作为蒙脱土-水分散体系的高温稳定剂，进行了磺化共聚物稳定剂的制备与表征；从流变学、滤失性能、粒度分布、电性质以及磺化共聚物在蒙脱土上的吸附作用等方面，对蒙脱土-水分散体系的高温稳定性进行了研究，考察了蒙脱土-水分散体系的高温稳定性能，同时提出了高温稳定机理。

Results Microscopically, AM was characterized by hypercellularity, high karyoplasma ratio, prominent macronucleoli, strange heterokaryocyte and tiny focal necrosis. Of 11 cases, recurrence was noted in three, and one transformed into anaplastic meningioma and died 1 year after reoperation.

结果 AM光镜下瘤细胞密度增大，核浆比例增高，核仁明显，多伴有奇异核细胞出现和微小坏死灶。11例AM病人中，3例复发，1例复发后转变为间变性脑膜瘤，再次手术后1年死亡。

A relationship between the frequency of occurrence and diversity of AM fungi and the elevation of the sampling sites for Swietenia macrophylla was observed. The elevation significantly affected the frequency of occurrence and diversity of Gigaspora and Scutellospora, but showed no significant influence to Glomus and Acaulospora.

通过对不同海拔高度Swietenia macrophylla根际AM真菌分布的分析表明，海拔高度显著影响着AM真菌的分布，Gigaspora属的真菌随海拔高度的增加显著升高，Scutellospora属的真菌则显著降低。

The highest spore density (7.32) was found in the soils of Swietenia macrophylla, while soils from the rhizosphere of Machilus namu were highest in species richness (5.37) and diversity index (1.6548) of AM fungi.

在所调查的10种热带常见树种中，Swietenia macrophylla根际AM真菌的孢子最丰富，密度高达7.32；Machilus namu根际的AM真菌种类则最为丰富，多样性指数达到1.6548。

The concentrations of NH+4-N,pH and NO-3-N first increased,but later they decreased smoothly. During the biodegradation process, AM was first hydrolyzed,then nitrified and denitrified,and the final products were oxidized into N2,CO2 and H2O.

不同时间段体系内NH+4-N、pH和NO-3-N都随着降解时间的增加逐步上升，但是达到一定时间后会下降，表明AM在降解过程中先水解，然后发生硝化反应，进而发生反硝化反应，最终AM降解成N2、CO2和H2O。

I am boradcasting on the all AM frequences.

我正在所有的AM调频上进行广播。

I am broadcasting on the all AM frequences.

我正在所有的AM调频上进行广播。

I am boradcasting on the all AM frequences.

内夫，我是纽约市的幸存者，我在所有的AM频道上进行广播。

Moreover, host plant can also affect the growth and development of AM fungi, and produce different infection rate、spore-bearing rate and mycorrhiza effect.

宿主植物也影响着AM真菌生长和发育，不同的宿主植物会影响AM真菌的侵染率、产孢量以及菌根效应。

With Death guitarist Schuldiner adopting vocal duties, the band made a major impact on the scene.

随着死亡的吉他手Schuldiner接受主唱的职务，乐队在现实中树立了重要的影响。

But he could still end up breakfasting on Swiss-government issue muesli because all six are accused of nicking around 45 million pounds they should have paid to FIFA.

不过他最后仍有可能沦为瑞士政府&议事餐桌&上的一道早餐，因为这所有六个人都被指控把本应支付给国际足联的大约4500万英镑骗了个精光。
