The phytoplankton biomass altered from 4.22 mg/L to 22.31 mg/L, averaging 12.29 mg/L. The diversity index of the phytoplankton (H =0.96) was relatively low. The zooplankton identified belongs to 19 species, and its biomass ranged from 3.75mg/L to 7.74mg/L, averaging 5.93mg/L. The diversity index of the zooplankton was relatively low too. In the cultured rice fields, the phytoplankton identified belonging 53 gena, 6 phyla.

在网箱养鳝塘中，共检出浮游植物40属，隶属于7个门；浮游植物生物量变化在4.22mg/L-22.3mg/L之间，平均为12.29mg/L；浮游植物的多样性指数相对较低(H=0.96)；共检出浮游动物19属，其生物量变化在3.75mg/L-7.74mg/L之间，平均为5.93mg/L；浮游动物的多样性指数(0.80)也相对较低。

Diverse and multi-level social public demand leads to diverse and multi-level resource allocating activities, which means that the expenditure structure optimization should follow certain principles, such as the principle of adaptability, harmony, efficiency and gradualness.

由于社会公共需要的多样性和多层次性，决定了为满足社会共同需要所进行的财政配置资源活动的多样性和多层次性，那么，财政支出结构的优化应遵循一定的基本原则，包括适应性原则、协调性原则、效益性原则与渐进性原则等。

The haplotype diversity index of of Bronze gudgeon in the lower reaches of the Yangtze River was 0.6071,which revealed a lower genetic diversity in mtDNA.

长江下游铜鱼线粒体DNA单倍型多样性指数为0.6071，线粒体DNA遗传多样性较低。

This study showed that population genetic diversity was much lower than other Gymnosperm and there was no distinct genetic differentiation among individuals in this population. In order to protect or preserve its genetic resource,it is suggested that the most individuals in the population should be selected as we can.

研究结果表明：AFLP方法是一种十分有效的检测种群遗传多样性的分子标记，既具有可靠性又有方便高效性；元宝山冷杉种群的遗传多样性水平很低，种群内各个个体间的相似性系数很大，遗传关系很近，无明显的遗传分化，这说明该种群的适应能力差、进化潜力有限，濒危程度很高；若要保护或保存这个物种的遗传资源，建议应该选择种群内尽可能多的个体进行保护。

Immune function is a essential activity of white blood cells. It was puzzled for the diversity and complexity of immune response. Polarized immune response of immune cells was discovered 30 years ago, which facilitates the study on differentiation of lymphocyte. Recently recognition on multifunctional polarized immune response of lymphocyte and monocyte/macrophage would promote to elucidate the regulatory network of immune cells, diversity and complexity of immune response as well as the study on hemopoiesis.

免疫功能是白细胞的主要功能，免疫反应的多样性和复杂性令人困惑。30年前发现的免疫细胞的功能性极化促进了对淋巴细胞分化的研究，近年来对淋巴细胞、单核／巨噬细胞功能多极化的研究为阐明免疫细胞的调控网络奠定了基础，为阐明免疫反应的多样性和复杂性提供了线索，也为深入研究造血细胞的分化拓展了思路。

By using four sample fields in Jiusheng village, Sandao town and Baiquan county, the paper studied the effects of different windbreak belt structures in hummock and hill district on biodiversity by means of the index, such as species richness , diversity index and biomass.

文章以拜泉县三道镇久胜村的4块样地为例，从物种丰富度指数、多样性指数、生物量等方面研究了漫岗丘陵区不同防护林结构对林下植物生物多样性的影响。

In the action of Dimilin, the diversity levels of Lepidoptera and Orthoptera insect of the treatment plot had a certain degree decline, and the diversity degrees of Hymenoptera insect and spider had a large increase, thus insect community in the treatment stand tended to be relatively stable.

在时间过程中，施药区鳞翅目和直翅目昆虫的多样性水平有一定程度的下降，但下降程度不如对照区大，膜翅目和蜘蛛的多样性水平则有较大程度的上升，因此林内昆虫群落趋于相对稳定。

Together with literature records, a total of 75 species or subspecies in 59 genera, 20 families and seven orders are now known from the Yinggeling area, representing 70.8% of the known fresh-water ichthyofauna and 80.0% of the known endemic fish species of the island.

利用多样性指数，得出鹦哥岭鱼类物种多样性最高的是南渡江流域的南开河和昌化江流域万冲河段的支流。

The results indicated that organic fertilizer at a rate of 75000 kg/ha or organic fertilizer (75000 kg/ha) with compound fertilizer at a rate of 300 kg/ha had higher effects on genetic diversity of soil microbial community under field conditions. Treatment of fertilizers as base application at level of 600 kg/ha resulted in decrease of DNA sequence richness index and diversity index of soil microbial communities, and the similarity coefficient of DNA sequence from soil microbial communities was the lowest compared with control. Organic fertilizer treatment was conducive to increasing DNA sequence diversity index and evenness index of soil microbial communities.

结果表明，在本试验条件下，基肥为75000kg/hm^2有机肥处理和75000kg/hm^2有机肥加300kg/hm^2复合肥处理最好；基肥为600kg/hm^2复合肥处理使土壤微生物群落DNA序列丰富度指数和多样性指数显著下降，与对照的DNA序列相似系数最低；有机肥处理有利于土壤微生物群落DNA序列多样性、均匀度和黄瓜产量的提高。

They weren't aggressive, but I yelled and threw a rock in their direction to get them off the trail and away from me, just in case.

他们没有侵略性，但我大喊，并在他们的方向扔石头让他们过的线索，远离我，以防万一。
