It was found that in the simulated physiological solution , the hydrogen bindings between some amido groups in the mp - 11 molecules are decomposed and the mp - 11 dimers become monomers . it induces the increase in the contents of the a - helical and ( 3 - turn conformation , the decrease in the content of the random coil conformation of mp - 11 as well as the increase in the exposure extent of the heme group . therefore , the reversibility of the electrochemical reaction and the electrocatalytic activity of mp - 11 for h2o2 reduction increase comparing the situation in the aqueous solution 發現在模擬生理條件下， mp - 11分子的多肽鏈上一些酰氨基的氫鍵發生了解離，使部分雙聚的mp - 11分子變成單體分子， mp - 11分子二級結構中-螺旋和-轉角結構的含量增加，無規卷曲結構含量降低，導致了mp - 11分子中血紅素的暴露程度變大，因此mp - 11電化學反應的可逆性和對h _ 2o _ 2還原的電催化活性比在水溶液中有所增加。

By means of the measure of entanglement called “ concurrence “ , we study the entanglement in heisenberg a single molecular magnets dimer v + with a strong magnetic field and find that thermal entanglement exits for both ferromagnetic ( fm ) and antiferromagnetic ( afm ) cases . in fm case entanglement vanishes for anisotropic parameter value = 0 , while in afm case , entanglement exits in the whole region of anisotropic parameter 0 < < 1 . an interesting conclusion is that the critical temperature is independent of the magnetic field 應用糾纏的一種測量“ concurrence ” ，對自旋二聚物v ~ ( 4 + )在外加強磁場情況下的熱糾纏進行了研究，發現對于鐵磁和反鐵磁兩種情況，熱糾纏都存在；鐵磁情況下，在各向異性常數等于零的時候糾纏消失，而對于反鐵磁在整個各向異性常數變化范圍內糾纏都存在，有意思的是我們發現臨界溫度獨立于磁場b ，我們也研究了糾纏度隨各向異性常數、磁場和溫度的變化。

Conclusion : it ' s possible to improve the expression efficiency by adjusting the g + c content of tir region and codon usage . replacement the cystein 78 and cystein 96 into serines , higher bioactivity gained compared with control hbfgf protein , and decreased amout of dimer and inclusion body , this suggested that free thiol group of cys78 and cys96 is the main reason of dimer and multimer formation 結論：通過調整tir區g c含量及增加大腸桿菌偏愛的密碼子，確實能提高hbfgf在大腸桿菌中的表達量，而將78和96位上的半瞇氨酸替換成絲氨酸后，得到的hbfgf的蛋白活性高于未改構蛋白，二聚體和包涵體減少。

Gfral is an extracellular protein that is attached to the outer cell membrane by gpi - anchor and could not transducted signalling directly . according to the original model , a gdnf dimer first binds to either monomeric or dimeric gfral , and the gdnf - gfral complex then interacts with two ret molecules , thereby inducing their homodimerization and tyrosine autophosphorylation 傳統觀點認為： gdnf首先與gfr 1結合形成gdnf - gfr 1復合物，此復合物再與ret結合形成三聚體復合物，引起ret的二聚化，并引起酪氨酸殘基自磷酸化，從而引起下游的信號轉導。

We research on the carbon dioxide dimers ( c2h and c2v ) by dft too . the results indicate that dissociation energies is kjmol - 1 and intermolecular vibration frequencies are small of both carbon dioxide dimers ( cah and civ ) . therefore we prove that the carbon dioxide dirners are weakly bound molecule indeed 采用量子化學計算手段，我們研究了co _ 2二聚體( dimer ) ，證實了co _ 2二聚體確實是弱結合分子，因而在超臨界狀態下co _ 2具有很強的動力學特征。
