In the dry land and garden plot, the soil eroding amount of terraced fields is only 1/3 of that be ploughed directly along the slope. It is difficult that assart along the contour in the dry land and garden plot, after the first 1~2 years, the soil eroding amount will increase at double. From the soil and water conservation point of view, the mode that integrates arbor, shrub and grass in woodland is the best, the mode that plants grass in bare land is the second.

This study showed that the most important fitness indicator for Taiwan is the amount of physical activity, including time and intensity of participation. The first concern of government should be the increase in number of people participating in physical activity and to make exercise as part of life style. Increased amount of physical activity could reduce the risk for many chronic diseases. The yearly fitness test should focus on the amount of physical activity conducted, the socioeconomic information, and the baffler of engaging physical activity.

Considerating over-all performance of mag nets, it was concluded that the optimal amount of doped-Ga was 0.5wt%. The other was that the grains size distribution of grains was narrow and grain distributed homogeneously as to microstructure of magnets when the amount of doped-Ga was 1 .Owt%;(3 ) In the magnets, there existed not only Nd2Fei4-xGaxB, but also GaNd concerning the Ga-elment form. The GaNd increased the amount of liquid and had favorable function during sintering, so it made for the increase of magnets density and the form of the second phase is good for improving coercivity.

By employing such a method, 5 series of elastomers, including natural rubbers, elastomeric polyester fibers and ethylene-octene, ethylene-methyl acrylate as well as SIS triblock copolymers, were investigated with the purpose of studying elongation induced phase structure and mobility changes of the samples. For NR samples, it was demonstrated that there exists a small amount of crystals at RT even for unelongated samples. For both NR and the soft segment of PEE, with the increase of elongation ratio, the elongation-induced crystallinity increases almost linearly in a certain region of R, in accord with the increase of the lamellar thickness of the crystals; The behavior of ethylene copolymers, in terms of elongation induced morphorpholgy changes, are quite different from NR and PEE. The crystals are found to be gradually destroyed with the increase of R, with accord with the decrease of the lamellar thickness; The motional behavior of the soft segment of SIS, changes from "liquid" to "solid", in terms of 13C NMR spin-lattice relaxation.For many of the aformented samples, the dependence of 13C spin-lattice relaxtion time T1 on R are different for different groups, indicating that the changes of mobility at MHz frequency region with elongation are different for different groups.

The results show that, with the increase in ionic strength, the adsorbed amount of taurine on the resin D290, the distribution coefficient λ and the fraction of zwitterion Tau(superscript ±) all decrease, while the pH value of the solution at the equilibrium and the content of anionic taurine Tau(superscript -) increase. Moreover, it is found that, at a certain taurine concentration, the increase in ionic strength may improve the selectivity of the anion resin for taurine.

The result of immobilization showed that hydrophile membranes were more advantageous than hydrophobe ones to act as immobilization carrier. Crosslinking organophosphorus hydrolase by glutaraldehyde on polyethersulfone membrane is a simple and practical immobilization method. An appropriate amount of bovine serum albumin and crosslinker is necessary to get a good result of immobilization. In the biodegradation of methyl-parathion through enzyme membrane reactor, the effect of immobilized enzyme amount, flow rate of peristaltic pump, pH of the feed, and the methyl-parathion concentration on biodegradation rate was studied. It was shown that the biodegradation rate increased with immobilized enzyme amount and substrate concentration. Biodegradation rate didn't increase when the folw rate of the peristaltic pump was larger than 7 ml/min.
