Fine resolution is used to largen the capability of channels as well as to improve the system agility 小步进跳频有利于增大信道容量,提高系统灵活性,也是一项重要指标。

We have to optimize the physical parameters synthetically to largen the region of the resonance , minish the range of jumping and increase the amplitude 而增大共振区,减小跳跃幅度,以及增大共振的幅值就需对系统各物理参数进行综合选择,以得到最优值。

Results of experiment show that the reason of strength decreasing of gypsum added with retarders is that the retarders reduce the supersaturation of liquid phase , and makes the crystal grain largen , and pore is followed to worsen , which lead to the strength drop to a large degree 实验结果分析表明：在掺加缓凝剂后石膏硬化体强度下降的原因在于缓凝剂降低了石膏的液相过饱和度，使结晶颗粒变大，使石膏的孔结构恶化，最终导致了宏观强度大幅度下降。

Our nation is transforming from traditional agriculture society to modern industry society and it ' s traditional institutions need change , too . under planned economy system . unit system of higher education was set after 1952 . in condition of the system of market economy , unit system of higher education has n ' t fit the need of universities and social development , so it must be transferred to contract system of higher education . which suits to the system of marketable economy . thus this will largen universities " scale . increase it ' s quality and benefit moderization of higher education and society 其中， 1952年以后的“高教单位制”是在计划体制之下形成的一种高教制度设置。在新时期的市场经济条件下，高教单位制已不适应高校和社会的发展要求，因而要对其进行变迁。继而要建立全范围的与市场经济相吻合的高教契约制，使高校的规模、质量、效益得到扩大和提高，实现高教现代化，从而致力于社会现代化。
