The three dimensional solubility parameters and solution properties of polytriethyltin methaerylate (PTETM) have been studied and determined. The investigation results are listed below:1. The intrinsic viscosity method was used for determining the three dimensional solubility parameters of PTETM. The results are as follows:σ= 18.8(J/cm~3)~(1/2) δ_d= 16.8(J/cm~3)~(1/2);δ_p = 6.28(J/cm~3)~(1/2); δ_h = 5.73(J/cm~3)~(1/2).2.

The K_θ parameter and Flory's characteristic ratio C_∞ of PTETM were evaluated:K_θ = 0.015; C_∞ = 9.4The relationships between δ and the structure of polytrialkyltin methacrylates and the structure effect of the chain flexibility were discussed.

Photosynthesis rates(PR for four single-celled algae were determined by ~(14)C-tracer method under the condition of varied temperatures(θ). PR varied with θ in the fashion of nonlinear functions. PR increased with increasing θ in the lower temperatures, however, it tended to decrease above the optimum temperature. The activation energies in the course of photosynthesis for Chlorella sp., Chaet. muellern, Chaet. socialis and Chaet. calcitrons are 23.05,30.71,50.46 and 66.02 kJ/mol, respectively. Chaet. calcitrons and Chaet. socialis with higher activation energies are adapted to grow under higher environmental temperatures. Chlorella sp. and Chaet. Muelleri with lower activation energies are adapted to grow under lower environmental temperatures. Theoretical calculations of activation energies are consistent with the experiment results of θ parameters for the growth of the four single-celled algae in our study.

In the lattice gauge theory with massless fermions, the transformation properties of the generating functional, the Hamiltonian, the vacuum states and the vacuum energy depending on the θ parameter under the chiral transformation are investigated. The vacuum energy has no connection with θ , i. e. the tunnel effect between the θ vacua in lattice gauge theory is suppressed, when there are massless fermions.
