重复试验

Some interaction between the laser power and welding speed are obtained by repeated two-factor experiments.

通过有重复的二因子试验，得出激光能量和焊接速度之间存在着一定的交互作用。

So maybe they were just following that strategy again when they saw the tube in the new experiment, the scientists suggested.

科学家们认为，因此当它们在一项新的试验中看到杯子时，可能只是重复这种方法。

Many biotic and abiotic factors are easily controlled in greenhouses, so the experiments can be replicated and the simulated research on the mechanisms of varied stress factors affecting natural complex ecosystems can be carried out conveniently.

温室内很多环境因子和生物因子是相对可控的，试验研究易于重复，方便开展各类胁迫因子对复杂生态系统影响机制的模拟研究，可作为一类中等尺度的mesocosm。

The overall goal of this project is to develop, test and deliver replicable tools that support local government efforts to create an enabling environment for sustainable economic development.

拙译：本项目旨在通过对可重复利用的工具的开发、试验和实施，支持地方政府营造可适应持续经济发展的良好环境。

The simulation experiment was carried out for 50 generations and 100 replications.

模拟试验共进行了50个世代，100次重复。

The experiments were conducted in a split plot design with 2 replications.

试验采用裂区设计，2次重复。

About 40 m2 plot size with three replications and randomized design were used in the trials.

试验小区面积40米2，三次重复，随机设计。

If n is large, and more replications are performed, the probability of rejecting the null at 5% level is 5%.

如果n足够大，而且将试验重复更多次，在5%水平上拒绝零假设的概率为5

The methods of IR and others were carried on in order toverify the structural formula of XN. The validation of analytical procedures wasconducted according to quality standard of XN in supplement of ChinesePharmacopoeia in 2002. The results show that the structural formula of XN isright and XN can be analysed in accordance with the quality specification of ChP.The results of three lots repeat tests show that the optimal process for XN wasrepeated excellently and quality of products is stable and controllable.

所合成的烟酸占替诺经红外分光光度法等波谱测定，证明其结构正确；经检验方法学验证，确证该产品适用于按《中国药典》质量标准检验；经三批次重复验证试验，结果表明优选的烟酸占替诺合成工艺重现性好，所得产品质量可控，收率为91.1%，接近文献报道的最高收率。

Objective: To observe production of antibody to rhbFGF, its neutralizing activity and deposition in kidney in conducting toxicity study on repeated doses of recombinant human basic fibroblast growth factor in normal rhesus monkeys and Wistar rats.

目的：在猕猴和大鼠中进行重组人碱性成纤维细胞生长因子的重复给药毒性试验时，观察给药后抗 rhbFGF 抗体的产生和抗体的中和性，以及抗体在肾脏的沉积。

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。
