Increasing the storage capacity became increasingly difficult because the recording laser could not penetrate the upper layers of data with sufficient power to change the state of lower layers 由于进行记录的激光束不能有足够的力度穿透上层数据层在下层记录层上进行操作，因此储存容量的增加也同时增加了技术难度。
Abstract : by establishing accurate mathematical model of underground gas storage , storage characteristics and permeating process can be described on quantity and therefore theoretical base of the underground gas storage optimum operation can be provided 文摘:通过建立枯竭气藏型地下储气库的数学模型，数值模拟出储气库储气的历史过程，予测储库的储存容量，研究储库注采动态特征。

A project was also carried out in the year to replace part of the fixed file racks of the departmental archives in chai wan and a few offices in the revenue tower with mobile racking systems . the use of mobile file racks has not only enlarged the file storage capacity , but also enabled the reshuffling of the concerned areas to enhance operational efficiency 年内，本局推行了一项计划，为位于柴湾的旧档案组和税务大楼的多个办公室更换部分固定组合文件柜，装设活动组合文件直推柜，加大档案储存容量，并让写字楼空间能够更灵活编配，从而提高工作效率。
