The modified double weight function method is to introduce new weight functions doing subtraction between two negative exponential-type functions. For a Pearson type three probability distribution, the MDWF is able to make estimations of the Standard Deviation and Coefficient of Skewness C(subscript S from the second-order weighted central moments reduced to the first-order weighted central moment estimations.

修改的双权函数法是将两个负指数型函数之差所构成的函数类取作权函数，对于皮尔逊Ⅲ型分布，它能使σ和Cs的估计由原权函数法的二阶加权中心矩降低为一阶加权中心矩估计。

从大梁钢坯横截面整体的原位统计分布二维成分等高图可以直观的看出，在连铸坯横截面上中心部位，硫形成一条较连续的"带状"偏析，磷形成一条不连续的"带状"偏析，其它元素中心"带状"偏析不明显。

The results show that the total acid amount changed indistinctively and strong acid sites increased relatively if the treated temperature was not higher than 400 ℃ even in two different treated media. However, the total acid amount decreased obviously and strong acid sites nearly disappeared as the treated temperature was beyond 500 ℃, and the second pore with different pore sizes formed and average pore diameter enlarged of MCM-22 zeolite catalysts after hydrothermal treatment.

研究结果表明，在两种不同介质中和处理温度不高于400 ℃条件下，催化剂的总酸量变化不大，强酸中心有所增加；处理温度高于500 ℃后，催化剂的总酸量明显下降，强酸中心基本消失；经水热处理后， MCM-22分子筛催化剂中形成了孔径不均匀的二次孔，平均孔径增大。

在影响社区活动中心使用因素上，本研究依实质环境因素与非实质环境因素（共九类22个变数），经由调查与统计结果发现：在实质环境因素部份，影响社区活动中心使用情形的因素有：区位分布与面临道路数等二个变数；非实质因素部份则为：妈妈教室的设置、管理员的设置、以及社区发展协会会员数等三个变数。

Setting up city track transportation system is the way to solve the traffic in the cities, and to realize substanable development. There have tow reasons: first, city track transportation has many merits, great capability, quick speed, safety on time, low cost, saving energy, catabatic traffic block on the ground, protecting the environment and so on; second, though track transportation, the develop derection of city constructure turns from single-center homocentric cirlarity mode to multi-center axes mode.

修建城市轨道交通是解决当前大城市交通问题、实现可持续发展的有效手段，其表现有二：第一，城市轨道交通具有运能大、速度快、安全准时、成本低、节约能源、能缓解地面交通拥挤和有利于环境保护等优点；第二，城市轨道交通的修建使城市结构的发展方向从单中心同心圆结构转向多中心轴线式结构。
