Effect of entophytic bacteria strain E1R-J on cabbage and radish seed germination, seedling growth was studied in plates, pot and outdoor field experiment.

通过萝卜、白菜的种子萌发试验、幼苗盆栽试验以及小区试验，对小麦内生枯草芽孢杆菌E1R-J菌株的促生作用进行了研究。

The valures of GI were 38.9, 6.3 and 1.1 at 30℃, 15℃ and 5℃ respectively. Shorea wantianshuea seeds could not be stored at 5℃, but it had short-period storage potential at 15℃.

望天树种子不能耐受5℃低温贮藏，但具有在15℃下短期贮藏的潜力和一定程度的生理性休眠。

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。
