Base on the problem of large quantity fatigue loads on corroded R.C. structure and small quantity study of its mechanical property, bending resistance fatigue test of corroded R.C. beams is discussed in this paper. The influence of stress ratio and re-bar weight loss ratio on bending resistance fatigue performance of corroded R.C. beams are researched, and the relation between strains of corroded re-bars and fatigue life of beams are obtained. The main research contents and conclusions are as following: 1. Under the fatigue loads, the overstrain of concrete approximately coincidences three stages strain development and accumulation rule, and the mechanical property of concrete is deteriorated. The fatigue damage of concrete is accumulated. The overstrain of re-bars increases and the increase rate decreases.

Suitable control content of culture medium can benefit growth, proliferation rate of Williams B6 seedling, save spending of production material. The content of 30ml per bottle show the highest proliferation rate and the higher usage of culture medium, the contrary result will appear when preponderate over the content of 30ml per bottle, but the increase weight of single seedling. For the losing of medium by sterilization, seedling SO2 resistance and other effects, it's considered the content of 25~30ml per bottle is fit for production of tissue culture seedling.

The above method can be used as a general method of determining molecular weight distribution of polymers.4.Solid-state ~1H wide-line NMR and ~(31)p magic angle spinningNMR were applied to a series of PEI/DNA complex samples with different PEI molecular weights and nitrogen/phosphatemolar ratios,in order to disclose the influence of various structural factors on the interactions and morphology.The results of ~1H NMR spectra showed that the linewidth of the PEI signal was greatly broadened with increasing the N/P ratio.Meanwhile,in the ~(31)p M_AS experiment,the signal was found to shift upfield with the increase of the N/P ratio.Both ~1H and ~(31)P NMR experiments demonstrated that the interaction between two constituents and subsequently the morphology of the complexes vary with the N/P ratio.
