金属有机化学物

This paper is a generalization and summation of some new progress in marine chemistry in the recent decade. The principal contents consist of seven parts:1. Oceanological survey. The oceanological survey covered the China Seas, the Pacific Ocean and the Antarctic Ocean.2. Interaction of minor elements and suspended matter in seawater and the theory of in-terfacial stepwise ion/coordination partical exchange.3. Effect of organic matters on the liquid-solid interfacial exchange and the rule of left-righ...

Rare earth organometallic chemistry is closely interrelated with materials science, organic synthesis, life science. Rare earth organometallic complexes containing Ln-C σ bond and involving silylene-bridged fluorenyl are of important significance in macromolecular and asymmetry organic synthesis.

稀土金属有机化学与材料科学、有机合成、生命科学等学科密切相关，含Ln-Co键稀土金属有机配合物和含硅桥配体稀土金属有机配合物在高分子和有机合成不对称催化领域具有重要意义。

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。
