The examples show that not only two binary complementary sequence pair sets can be used to construct a new binary complementary sequence pair set,but also it can be extended to the design of new binary complementary sequence pair set through several individual ones. This method can extend the existence space of binary complementary sequence pair set.

As important industrial chemicals, dihydroxy alcohols are applied for many fields, classical dihydroxy alcohols include l,4BD0, diglycol, NPG, 1,3PDO, HDO and so on. MPO is a kind of new dihydroxy alcohols. Because of its unique molecular structure, 2-methyl-1,3-propanediol is instead of classical dihydroxy alcohols gradually. So MPO has huge market foreground.

A method for cold transportation of goods that are placed in a hollow-walled refrigerating container, comprising the following steps: storage of a pumpable solution of tiny ice crystals, known as binary ice, having a given composition and temperature, in a binary ice store until said binary ice is used for refrigerating or filling purposes; the optionally filled wall of the refrigerating container that is to be used is emptied via an outlet valve for the binary ice; binary ice is allowed to circulate inside the refrigerating container via filling instruments that are supplied with binary ice from the binary ice store until the temperature of the wall drops to a given temperature, whereby the heated fluid that is discharged from the outlet valve is fed to a binary ice fluid store; the wall of the refrigerating container is filled with a given amount of binary ice; the refrigerating container is decoupled from the filling instruments; the binary fluid that result from the melted binary ice is returned to a corresponding binary fluid store in order to produce new binary ice from said binary fluid.

During the last decade, many studies have hypothesized that the MADS-box proteins could form specific dimers, which would be further assembled into tetrameric complexes to have more functions. In order to prove whether BCFMADS and CCFMADS genes can interact with each together to form either homodimer or heterodimer, we used an in vitro approach to analyze protein expressions for both genes.

MADS-box基因中，基因并不会单独的表现，而是透过形成同质二元体、异质二元体或是蛋白质复合体来表现其基因的功能性，因此本研究为欲证实BCFMADS以及CCFMADS基因间可否形成同质二元体或是异质二元体，乃利用E。
