Ming dynasty , sliced bread district court has not yet fully formed , sliced bread , the family village level interaction model that in the dynasty years in sales growth period , basic to court , sliced bread secondary form of interactive campaign to qing dynasty " hong dry time " period before a fill scale and rapid into court with the family of the village of interaction between secondary mode 明朝时，土司区尚未完全形成朝廷、土司、家族村社三级互动模式，这种模式在明洪武年间处于发育期，基本以朝廷、土司的二级互动形式进行运动，到清朝“康乾盛世”时期才形成蔚为大观的规模，并迅速转化为朝廷与家族村社之间二级互动模式。
To lily flower of high quality characteristic production in qingyang carry through plastic pellicle mantle and maize straw pole mantle in live through the winter , analysis soil water resume , ground temperature change character and different mantle material water , heat resource to the effect of upgrowth period , growth measure and output inscape of lily flower 摘要通过对庆阳优质特色产品黄花菜越冬期进行地膜覆盖和玉米秸秆覆盖，分析越冬期土壤水分损耗、早春地温变化特征，以及不同覆盖材料水、热资源对黄花菜发育期、生长量、产量构成要素的影响。
( 3 ) according to the new methods of dynamic numerical simulation analysis , the computation model of the deep cutting gorge is contracted with flag30 software and flag30 pre - processing package , the reasonable simulation course is designed and the calculating results is controlled effectively . finally , the forming process and the evolution features of the 4 stages geo - stress field evolution in xiluodu gorge are displayed in the paper , from which the variable regulations are analyzed and summarized systematically . these achievements can be regarded as creditable evidences for technocrats to solve some problems of geo - stress field in xiluodu area ( 3 )按照动态数值仿真新思路，运用flac ~ ( 3d )软件及flac ~ ( 3d ) pre - processingpackage ，建立了深切峡谷区仿真计算模拟，设计出了较为合理的仿真过程方案，有效地控制了结果的输出，重现了峡谷形成过程中四个发育期的地应力场特征，并对峡谷区地应力场的演变过程进行了动态的系统研究与分析，其研究成果对分析、解决溪洛渡深切峡谷区地应力场存在的难题，提供了可靠且有力的依据。
The accumulated temperature of each stage of cynoglossus semilaevis gu nther was calculated with the record of the time and the temperature according to the principle of accumulated temperature . the summation of all the accumulated temperature was necessary with which the fertilized egg could get through its development of the embryo stage . the summation was 837 . 92 ( hour * ) , and the average temperature was calculated to be 21 . 0 according to the summation and the total time 通过对孵化时的温度和时间的记录，由积温法则计算出半滑舌鳎各个发育期所需要的积温，整个孵化期所需总积温为各个发育期的积温之和，最终结果为50275 . 1 ( min ~ * ) ，孵化的平均温度通过总积温和孵化总时间计算得，孵化阶段的平均温度为21 . 0 。
