The new technology will increase communication speeds tenfold to one gigabyte per second , from around 100 megabytes per second for optic - fibre services now available , an ntt spokesman said , confirming a saturday report in the nihon keizai shimbun daily 光学纤维。一位ntt发言人证实星期六日本经济新闻里报告时透露,新技术将可以使光纤传输速度增加10倍,光纤能够提供的速度从目前大约100兆字节每秒提高到10亿字节每秒。
This synthesising mind , gardner writes , “ takes information from disparate sources … and puts it together in ways that make sense to the synthesiser and also other persons … the capacity to synthesise becomes ever more crucial as information continues to mount at dizzying rates ” 加德纳写道,这种综合分析的思维“会接收不同来源的信息… …并将信息整合成他和其他人能够理解的形式… …随着信息继续以令人眩晕的速度增加,综合分析能力变得更为重要。 ”

According to statistics , since 1995 , the enterprises which join in the ec in the northern america , western european and the japan has increased by the speed of doubling per month , and according to the idc ( international date corporation ) ’ s deduce , in years between 1997 to 2001 , the volume of trades of ec in northern america has been increased from $ 8 , 500 , 000 , 000 to $ 155 , 100 , 000 , 000 , and the volume of trades of ec in asia - pacific region has been increased from $ 720 , 000 , 000 to $ 30 , 600 , 000 , 000 据统计,自1995年以来,北美、西欧和日本加入互联网的企业以每月翻一番的速度增加,另据国际数据公司的推断,从1997年到2001年,美国的互联网电子商务交易额从85亿美元增长到1551亿美元,亚太地区的互联网电子商务交易额从7 . 2亿美元增长到306亿美元。
The results show that the wayside noise increases 8db - 12db , if the train ' s velocity increase two times ; and increases 3 db , if the number of axles increase tow times ; and decreases 3db , if the distance far away from the track increase tow times damping loss factor increases , the wayside noise decreases ; coupling loss factor increase , the wayside noise increase 预测结果表明:列车通过时,在其他条件不变的情况下,列车速度增加一倍,轮轨辐射噪声大约增加8db 12db ;列车轴数增加一倍,轮轨辐射噪声大约增加3db ;预测点距轨道距离增加一倍,轮轨辐射噪声大约降低3db 。
The paper summarized the research for the effects of different grazing intensity on grazing behaviour , grazing grass species and productivity of sheep in recent years , the result showed that : there was a negative correlation between the live weight gain per sheep and the grazing intensity , but there was positive correlation between the live weight gain per hectare and the grazing intensity ; feeding intake of sheep decreased when the grazing intensity become heavier ; there was not significant effect of different grazing intensity on sheep breeding indexes ; as long with the grazing intensity become heavier , the feeding time of sheep increased while resting and idling time decreased , but feeding intake per hundred mouths and daily intake reduced while intake velocity increased ; sheep feeding adaptability is relative ; the light grazing was beneficial to promote mutton quality , but mutton quantity and gross economy benefit was low 摘要根据近几十年来放牧强度对绵羊放牧行为、采食植物组成和生产性能的影响进行了综述,得出以下结论:绵羊的个体增重与放牧率之间呈线性负相关,而公顷增重与放牧率之间呈正相关;绵羊的采食量随著放牧强度的加重而降低;放牧强度对母羊繁殖性能各指标影响差异不显著;随著放牧强度的加重,绵羊的采食时间增加,游走、反刍卧息时间减少;每百口采食量和日采食量减少,而采食速度增加;放牧绵羊的嗜食性是相对的;轻牧有利于提高肉的品质,但是产肉量低,总的经济效益不高。
Due to the rapid development of network technologies , the network bandwidth and the rate of network transmission has been enhanced greatly . however , the data that need to be transmitted has also incremented with the same rate , even exceed the incrementing rate of network bandwidth . this fact indicates that the network bandwidth is still a key issue for network transmission 当前,尽管由于网络技术的发展,网络带宽以及网络速度都得到了极大的提高,但需要通过网络传输的数据却也几乎以与网络发展速度相同的速度增加,甚至超过网络发展的速度,这使得网络带宽与网络速度依然是一个关键问题。
If a < c < s , it means that the visible height of stone pillars will increase . as its actual height increase ; however , the soil layer will become thiner and thiner , and when the soil is eroded up in the end , the differences between sub - aerial and sub - soil dissolution will disappear , then , a will be proximately equal to c , the actual height will stop increasing or increase very slowly , so the so the stone forest will become shorter and shorter with various kinds of chemical and physical wheathering 对路南地区的a 、 s 、 c三因子的综合研究表明,在现代自然条件下,石林的实际高度仍以15 . 77mm ka的速度在拔高,石林的可见高度现正以639 . 6mm ka的速度增加;促使石林增长拔高发育的源动力? ?土壤正以623 . 83mm / ka的速度快速变薄,说明虽然目前石林的高度仍在增加,但其发育的最佳时期己经过去。
With the subtrate temperature ' s increasing , the reaction rate increased , the crystal type was transfered from anatase to rutile , the roughness increased , causing the increase in hydropilicity . when substrates " temperature ranged from 450 ~ 550 , the tio2 films were composed with the mixture of rutile and anatase , and the photocatalysed efficiency was the best 随着基板温度的升高,反应速度增加,结晶类型由锐钛矿相逐渐向金红石相转变,粗糙度增大,亲水性逐渐升高,光催化效率在锐钛矿和金红石混合晶型时最佳。
The analysis results show that the palcement styles and the rotating angles of such a large scale deployable boom systems are functional importantly . the motions and damps of the boom systems also take importance . if motions become larger , the time for the booms to reach their spreaded states is shorter , and the impact velocities become larger , the impact accelerations become larger too 分析结果表明,对于大尺度的伸杆机构,其布置方式和展开角度对其展开运动有重要的影响;同时也研究了铰链处外力矩对展开运动的影响,随着该力矩的增大,伸杆到达锁定状态的时间减少,碰撞时的速度增加,由此产生较大的加速度;分析了伸杆弹性和阻尼对伸杆展开过程的影响,弹性增大碰撞加速度增大,阻尼增大加速度减小,因此可将铰链处外力矩和伸杆阻尼作为伸杆展开运动调节的手段。
