The results of large - scaled culture show that 48g clone crushed by tissue disintegrator in the course of initial period and its inoculating density is 0 . 35g / l , a month later , the clone departed directly and its density is 1 . 5g / l , the highest density of each jar could be obtained 410g , the growth speed mostly doubled per week 大规模培养结果表明在20l广口瓶中(有效水体15l ) , 48g克隆在起始培养时经组织捣碎机粉碎切割,切割时间10s (细胞段长度约200um ) ,并按0 . 35g l接种,一个月后不粉碎直接分瓶,分瓶密度1 . 5g l ,一个月后最大密度410g瓶,生长速度约每周翻一番。
The article structure the landslide prevention and cure , the structure of prestress anchors and its application in detail . basing on the geology condition of fabricating yard , we calculate the solid power and the length of anchor rope . we have worked out the experiment research scheme , and has carried on the earlier stage experiment , field demarcation experiment and has opened pulling the experiment on the spot . ten teams of steel rope to two teams of structure types twist the experimental data that thread internal stress and the total pulling force has been in progress research , and has put forward raising the measure of solid capability of prestress anchor and administering possessing 本文以川藏公路滑坡路段为研究对象,对滑坡的治理、预应力锚索的结构、作用及其在滑坡防治中的应用进行了详细的分析;基于施工现场的地质条件,对锚索锚固力及锚索最佳锚固段长度进行了理论计算;制定了实验研究方案,进行了前期实验、现场标定实验、实地张拉实验;对两组结构型式的十组钢绞线内应力及总张拉力的实验数据进行了研究,提出了提高预应力锚索锚固性能的措施,以及具体的施工方案和施工工艺。
In boundary treatment , the model turns into generally adds coarseness boundary made of specially complex many coarseness body in the physical model experiment as the coarseness body highly and discharges the density to add the coarseness spot as the main characteristic whole , both to avoid the location within the body of this complex mathematical simulation problems , and could realize this model after to simulate the apron that adds the coarseness namely adds the coarseness section downriver speed of flow to the downriver current of water base speed of flow influence in to hang upward 该模型在边界处理时,将物理模型试验中由特别复杂的多个加糙体组成的加糙边界概化成以糙体高度为主要特征的整个加糙部位,既避开了对加糙体内部进行极其复杂数学模拟的这一难题,又能实现模拟海漫加糙段下游水流流速在垂向上的分布变化这一主要目的。在获得基本的入流流速分布、初始水位及加糙体的绝对高度和加糙段长度的情况下,能迅速模拟出加糙段下游各个断面在垂向上的流速分布情况。
