A rotarian in the district gave a us $ 10 , 000 gift to the permanent fund . why is this not reflected in the district ' s ddf balance 问：区内有一扶轮社员捐了10 , 000美元给永久基金。为何没有反映在本地区的地区指定基金馀额上？
However , districts should be encouraged to use as much ddf as possible to make it available for programs in the first program year it becomes eligible 可是，应鼓励地区尽可能使用地区指定基金，使得地区指定基金在可以开始动用的第一年就能用在计划上。
Many are now offering a set amount of ddf to each club to use in matching grants further emphasising the sharing nature of the rotary foundation 时下许多提供每一个扶轮社一定数量的地区指定基金ddf用于配合奖助金，这是更进一步地强调扶轮基金的分享的本质。
In this way , the telephone exchange will leave a very small footprint , and the 2mbits ddf may be removed , thus substantially bringing down the total investment 这样，电话交换机占地面积很小， 2mbits的ddf可以去掉； sdh省去了2mbits板，使总投资明显下降。
Fifty percent of general earnings from permanent fund gifts will be credited to the donor district ' s ddf , if so requested by the donor at the time the donation is made 如捐献者于捐献时提出要求，永久基金捐献总获利的50 %将可归入捐献者所属地区的地区指定基金。
No matter whether in the pdh or sdh transmission network , the use of 2 mbits trunks to connect to the switch needs large amounts of hw equipment , including cable and ddfs 无论是pdh传输网还是sdh传输网，交换机采用2mbits中继与其连接都需要大量的硬件设备，包括电缆和ddf设备。
The results show that the performance of ddf communication system is much better than common fiber in the aspect of not only pulse transmission without aberration but also pulse compression 研究结果表明：无论是在脉冲的无畸变稳定传输方面，还是实现脉冲压缩方面， ddf都有着常规光纤所不能比拟的优越性。
Moreover , different ddf has respective advantage in different application area . it provides the scientific gist to exert the optimum performance of different type of ddf in practice 而且，不同类型的ddf在不同的应用领域各有其优越性，这为实际中趋利避害、更好的发挥不同类型ddf的最佳性能提供了科学依据。
For example , every year nearly $ 4 million in unused scholarship funds ( the difference between share cost and actual scholar expenses ) are credited back to indi ? vidual ddf accounts 例如，每年将近有400万美元的奖学金未动用（分享制度费用与奖学金学生实际支出的差额） ，最后都归还给各个地区的地区指定基金帐户。
The use of these paths simplifies effectively the network and reduces the number of digital distribution frames ( ddfs ) , connecting lines and shelves of 2 mbits terminal boards as well as simplifies maintenance Stm - 1通路的使用，有效地简化了网络，减少了数字配线架ddf和连接线， 2mbits端路板的机架数目减少，并且简化了维护。
