土壤呼吸和土壤活跃微生物量是衡量土壤微生物特性和土壤酶的较好指标。

Soil respiration and active microbiomass were good indexes of soil microbial characters and soil enzyme.

在土地利用方式变化过程中，土壤质量变化体现在有机质含量、土壤供持水能力、土壤结构状况和土壤微生物特性的变化上。

When land use patterns changed, changes in soil quality were embodied in content of organic matter, soil water holding and supplying capacity, soil structure and soil microbial characteristics.

以滨海盐土、扰动人为新成土（客土）为对照，就利用海湾泥、碱渣和粉煤灰作为城市园林绿化种植基质的土壤微生物特性进行了研究。

The microbial properties of artificial soil mixed with brackish dredged sediment, caustic sludge and coal ash were studied, with coastal solonchak and Turbi-Anthric Primosol as the control.

Again, these plasmids occur naturally in nature; they were discovered particularly in micro-organisms have plasmids that confer biological properties onto them.

此外,质粒存在于自然界中,质粒是在微生物中发现的,它们也赋予了微生物一些生物学特性

This is one of the biological properties, the naturally occurring properties of plasmids, is that they exist in microbial populations and they confer on them resistance from toxins that would ordinarily kill them.

这就是这类生物学特性之一,它是质粒所具有的自然特性,这些质粒存在于微生物群体中,并赋予微生物抗性,使它们免于被毒素杀死
