Science has to do with discovering the facts and relationships between (2) phenomena in nature and with establishing theories that (3) to organize these facts and relationships; technology has to do with tools, techniques, and (3) for applying the findings of science. Another (5) between science and technology has to do with the progress in each.

Progress in science (6) the human factor. Scientists, who seek to understand the universe and know the truth within the highest degree of (7) and certainty, cannot (8) their own or other people’s likes or dislikes or to popular ideas about the fitness of things.

NOKIA设备，假设网络有个站是2＋2＋2配置（1个BCF、1个E1）；语音业务：要求每个BTS的忙时平均话务是8erl，阻塞率是2%。数据业务：要求每个BTS的平均数据吞吐率要到200Kbits，静态时隙需要配置3个。另外，基站和载频都支持EDGE，没有开半速率，2个TRX的平均预留时隙（MeanfreeRTSL）1.5个。请问这些BTS还有多少容量可供数据业务使用？如果要达到数据吞吐率的要求，BTS的GPRSCDEF动态信道应该设置成多少？另外基站的配置是否满足这些需求？
