The results showed seasonal variation in both optimum leaf temperature for photosynthesis and light saturated photosynthetic rate at optimum leaf temperature, which ranged from 22 to 28℃ and closely tracked the mean air temperature to which the leaves were exposed in previous 5～10 d.

A microcalorimetric study of the optimum temperature of a starch enzymatic catalyzed reaction;

Quantitative relationship of characteristic sequence and optimum temperature of xylanases in G/11 family;

A uniform design based neural network model for amino acid composition and optimum temperature of alcohol dehydrogenase;

On the incredibilities of the reasonings in some papers for questioning about the optimal temperature of saliva amylase;

The optimal temperature,pH and Km of P-E were also determined respectively.

The results show that the optimal temperature and pH are 45℃ and 5.

In order to study the thermal adaptability of the common giant toad(Bufo gargarizans),and to test the optimality models, preferred temperatures,high avoidance temperatures and lethal thermal maxima of this species at different earlier developmental stages were measured against an artificial thermal gradient.

The method of preferred temperature,avoidance temperature and critical temperature,different method to experimental result influence and influencing factor of ectothermy\' s thermal adaptation were summarized in this essay,which will provide the method foundation for research on ectothermy\'s thermal adaptation.
