查询词典 metal

Studies of the binding of metal to calmodulin and the subsequent binding of metal-calmodulin complexes to the target protein/peptide revealed that the La-content calmodulin complexes to its target exhibit similar affinity with the Ca-calmodulin complexes.However, there were substle differences in protein conformation as well as the kinetical properties between the two kinds of metal-calmodulin complexes, suggesting Ln could produce cellular effects via the Ca/calmodulin signaling systems.

In order to get the information of interaction between metal complex and DNA and select metal complexes which can cleave DNA effectively, twenty seven transition metal complexes containing O/N coordinate atoms have been synthesized in this thesis. We report the synthesis, crystal structure and properties of the complexes. One of the complexes is the first μ〓-oxalato tetranuclear Cu complex, in which there is ferromagnetic interaction between the copper atoms bridged by oxalate ions. Two trinuclear copper complexes containing partial cubane Cu〓O〓 cores have been synthesized and discussed the magnetic properties.

This thesis is trying to prove the law of money evolvement with the history of Chinese monetary modernization. Money is evolved from none-precious metal to precious metal; from money by weight to coins made of precious metal, from convertible bank notes to unconvertible bank notes.

本文试图，用中国近现代的货币制度现代化情况来印证货币的演变规律：货币的演变是从具体物品到抽象符号，从贱金属即从按重量交易的贵金属发展为用贵金属加工成的铸币，在发展为可兑换贵金属铸币的纸币，最后发展为不可兑换纸币的这样的一个过程。

Zinc was recognized in Europe as a separate metal in the 16th century when Agricola (1490 – 1555) observed that a metal called "zincum" was produced in Slesia and Paracelsus (1493 – 1541) stated clearly that "zincum" was a new metal.
