特大型地下厂房岩壁梁锚杆和混凝土施工技术及质量控制

岩壁梁是一种新型结构，为通过一定深度的锚杆将钢筋混凝土梁固定在地下厂房两侧的岩壁上，而吊车荷载则通过锚杆和钢筋混凝土与岩石接触面的摩擦力传到岩体上，形成岩壁梁和岩体共同受力的结构。岩壁梁是地下厂房施工和运行的核心建筑物，岩壁梁锚杆和混凝土的施工质量是直接关系到岩壁梁成败的关键，所以施工技术和施工质量均要求极高，是地下厂房系统施工的重点和难点。本文介绍了瀑布沟水电站地下厂房岩壁梁锚杆和混凝土施工的关键技术及质量控制经验，可供同类工程借鉴参考。

Cyclic variations in the permeability of the cell wall of Saccharomyces cerevisiae.

To study cell-cycle-related variations in wall permeability of Saccharomyces cerevisiae, two approaches were used. First, an asynchronous culture was fractionated by centrifugal elutriation into subpopulations containing cells of increasing size. The subpopulations represented different stages of the cell cycle as judged by light microscopy. Cell wall porosity increased when these subpopulations became enriched with budded cells. Secondly, synchronous cultures were obtained by releasing MATa cells from alpha-factor induced G1-arrest. These cultures grew synchronously for at least two generations. The cell wall porosity increased sharply in these cultures, shortly before buds became visible and was maximal during the initial stages of bud growth. It decreased in cells which had completed nuclear migration and before abscission of the bud had occurred. The porosity reached its lowest value during abscission and in unbudded cells. We examined the incorporation of mannoproteins into the wall during the cell cycle. SDS-extractable mannoproteins were incorporated continuously. However, the incorporation of glucanase-extractable mannoproteins, which are known to affect cell wall porosity, showed cyclic oscillations and reached its maximum after nuclear migration. This coincided with a rapid decrease in cell wall porosity, indicating that glucanase-extractable mannoproteins might contribute to this decrease.
