One transmission cell to another while maintaining the DVB-H service.· For a number of reception scenarios; indoor, outdoor, pedestrian and inside amoving vehicle, the transmission system shall offer sufficient flexibility and scalability to allow the reception of DVB-H services at various speeds, whilstoptimizing transmitter coverage.· As services are expected to be delivered in environments that suffer high levels of man-made noise, the transmission system shall offer the means to mitigate their effects on the performance of the receiving terminal.· As DVB-H aims to provide a generic way to serve handheld terminals in various part of the world, the transmission system shall offer the flexibility to be used in various transmission bands and channel bandwidths.

因此DVB-H采用分时方式的资料传送形式，把原本通道频宽是由其它节目共同分配享有的，现在只可以让某一个节目使用全部的频宽所以让节目传送的位元率提高了，相对的减少传送的时间，但跟DVB-T一样在单位时间内所传送的资料是一样多的，由於DVB-H采用分时多工的方式传送资料所以接收器只在该节目传送的时间内接收该笔资料，而其它时间则不接收然后在等一个单位时间内，该节目的资料再传送时在接收，如此开关开关达到收到整部节目的资料，并大量的减少持续接收节目所消耗的功率，接下来由於DVB-H采用4K正交分频多工编码的方式，虽然涵盖的范围没有DVB-T大但对高速移动的时候接收信号时的效果会比较好。

Results:In each stage of follow-up,RPR test titer descended 2 titers or above in 48.6% at 3 months after treatment;78.4% at 6 months; 94.6% at 9 months;became negative in 83.8% at 12 months contrastively.

Finally, in additional to the comparison of results derived by PPP and DGPS, they were all compared to Anping tide gauge records as well. The aim of this study is the analysis of height variations provided by different methodologies. Comparing to Anping tide gauge records, the differences in height variations can achieve 4.5 cm with DGPS; 6 cm with final product; 10 cm with rapid product; 25 cm with ultra-rapid product; 1~2 m with ultra-rapid product.

实验中也搜集了安平潮位站的潮位资料，故也将此资料与GPS浮标高程方向定位成果进行比较，而研究中将著重於高程变化量之分析，假设潮位仪观测海水面高程变化量为参考解，由实验结果可发现差分相对定位椭球高变化量均方根误差之平均值约4.5公分；使用最终产品时椭球高变化量均方根误差之平均值可以达到6公分以内；使用快速产品时椭球高变化量均方根误差之平均值可以达到10公分以内；使用超快速产品观测部分於观测环境理想时椭球高变化量均方根误差之平均值可以达到25公分左右；使用超快速产品预估部分时椭球高变化量均方根误差之平均值约1~2公尺。

Now it was a herd of diabolic shapes, that grinned and mocked at the pale minister, and beckoned him away with them; now a group of shining angels, who flew upward heavily, as sorrow-laden, but grew more ethereal as they rose.
