生物量

Two fungal strains C —1 and 3—2 with high adsorption capacity and resistance to zinc and lead were screened. The strain C—1 was characteristic of great biomass, rapid growth and was able to produce spores even in the concentration of 100mg/L zinc ions.

筛选出两株分别对锌离子和铅离子有一定耐受性、吸附载量高的C—1和3—2真菌菌株。C—1菌株生物量大、生长速度快，在锌离子浓度为100mg／L的水溶液中仍能生长产生孢子。

While total biomass and yield of most legume crops is lower than cereals, legume seed and leaf protein concentrations can be several times higher.

大多数豆类作物的产量及总生物量低于谷类作物，但豆类种子及叶片中的蛋白质含量却高几倍。

Low abundance and poor compositions of nitrogen utilizing bacteria suggested poor bacterial diversities and weak self-purification of the lake.

这些功能菌群较低的生物量和不太丰富的生物多样性预示着湖泊弱的水体自净能力。

Finally, sciophilous species Saussurea macrota and light-loving species Salvia przewalskii presented larger plasticity indexes in biomass allocation and morphological characteristics than neutral-habitat species Senecio scandens.

喜阴物种大耳叶风毛菊和喜光物种甘西鼠尾草比中性生境物种千里光表现出了较大的性状特征和生物量分配的可塑性指数。

Generically, forest restore is thought would sequestrate more atmosphere carbon, but carbon sequestration through aboveground biomass increasing may be offset by soil organic carbon loss.

一般认为，恢复森林可以增加碳汇，但在较为湿润的地区，灌木、树木入侵引起的地上生物量增加将被土壤有机碳的流失所抵消。

The effects of different fertilization on soil microbial biomass C, N, P and maize yield in light sierozem were investigated with a field experiment, which was continued for 4 years at Hongsibu irrigated area of Ningxia.

通过设置在宁夏红寺堡灌区开垦4a的淡灰钙土上的定位试验，研究了不同施肥对新垦淡灰钙土微生物生物量碳、氮、磷及玉米产量的影响。

The compound application of chemical fertilizers and sheep manure not only increased the contents of microbial biomass C, N and P but also raised the yield of maize, therefore, it was the best fertilization measure in the newly cultivated light sierozem.

化肥与有机肥羊粪配合施用既能显著增加土壤微生物生物量碳、氮、磷含量又能使玉米产量显著提高，因此是新垦淡灰钙土施肥的最佳选择。

The photosynthetic rates from the stationary state to the strong water flow state were also decreased.

藻类种类数以小水流时最高，其生物量也最高，这与NO-3／TDN比值相一致。

In flask shaking culture, the output of CDEP-1 increased in parallel with the accumulation of biomass during the logarithmic growth phase and reached the peak value in stationary growth phase, then fleetly decreased in decay period.

摇瓶发酵结果表明，在对数生长期，随着菌体生物量的增加，CDEP-1产量上升，二者呈一定的平行关系；当菌体生长到稳定期，CDEP-1产量继续上升，并达到产酶高峰；此后，随着菌体生长的衰退，CDEP-1产量出现快速下降趋势。

The result indicated that soil moisture change affected biomass distribution in different organs, i.e., accumulative CO2 assimilation distribution. White clover could escape drought by increasing dry matter distribution in stolon and root system.

结果表明：土壤水分变化首先影响到生物量在植物不同器官的分配，即累积性的CO2净同化产物的分配，白三叶能够通过提高匍匐茎、根系的干物质分配比例来回避干旱。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
