The results indicated that there was no significant difference in hemolymph proteins between irradiated individuals and the controls. Only the concentration of 70kD proteins in irradiated silkworms were observed higher at day 0 of the 5th instar and lower at the later stage of the 5th instar than those of the respective controls.

但在成分分析时发现，5龄起蚕血淋巴中70kD附近的3条蛋白质谱带比对照蚕的浓度要高，随着个体的发育两者的浓度都上升；5龄后期则相反，对照蚕的浓度比照射蚕高；脂肪体中贮藏蛋白质的含量具有相似的变化趋势。

Methods: The 4 months and 17 months rats were selected as subjects, and the histochemistry methods were used in muscle cell observ ation.

The results indicate that its dynamic stress-strain curve is hyperbolic type. The dynamic strain of LCES decreases with increasing confining pressure, cement content, curing ages and cyclic loading frequency when it is subjected to the same dynamic stress. At the same dynamic strain, the dynamic secant elastic modulus E_(sec of LCES increases and the damping ratio decreases with increasing confining pressure, cement content, curing ages and cyclic loading frequency. The curves ofσ_d～ε_d,E_～ε_d and D～ε_d with different EPS content intersect respectively, the trend of LCES deformation characteristic is inversely proportional to EPS content near the intersection. The value of dynamic strain at the intersection is about 0.5%~3.0%, the magnitude of which is related to the mixing proportions and confining pressure.

试验结果表明，LCES的动应力应变骨干曲线形态符合双曲线；在相同的动应力作用下，LCES产生的动应变随着固结压力、水泥掺量、试样养护龄期和振动频率的增大而减小；在动应变相同的情况下，随着固结压力、水泥掺量、试样养护龄期和振动频率的增大，LCES的动模量增大而阻尼比减小；随着加载次数的增大，LCES的动模量在开始阶段显著降低，然后趋于稳定，但当加载次数达到几百次时，动模量又有增大的趋势；不同EPS掺入比的LCES的动应力应变骨干曲线、动模量随应变变化曲线和阻尼比随应变变化曲线都发生了相交，交点前后EPS掺入比的大小对LCES动力变形特性的影响趋势是截然相反的，交点处的动应变值一般在0.5％～3.0％范围内变化，其大小与LCES的配比以及固结压力有关。

The smears were stained with modified ziehl-neelsen method and observed under oil immersion lens.

Part 1: Fifty-four healthy cross-bred(Luxi×Limousin) beef cattle were selected to study the energy and protein metabolism rules and requirement at the age of 4~6 month. The results showed that the digestibility of DM , OM and energy were 59.68±5.46%, 64.10±7.82% and 66.60% respectively;the metabolizability of gross energy and digestible energy were 56.95% and 85.51%.
