Researched influence of frequency on characteristic of electromagnetic wave transmission in tunnels, and analyzed characteristic of electromagnetic wave transmission in circular, arches and curved tunnels by method of metal wave guide, and gives approximate formulas of attenuation rate. Main conclusions we obtain are as follows: in circular,rches tunnels, if frequency is higher, attenuation rate is smaller, it is beneficial for EM waves to transmit, in curved tunnel, higher frequency, more attenuation rate ...

研究了频率对井下电磁波传输特性的影响，采用金属波导法分析了圆形、拱形及弯曲隧道中电磁波的传输特性并给出衰减率近似公式，得出主要结论：在圆形和拱形隧道中，频率越高，衰减率越小，越有利于电磁波的传播；在弯曲隧道中，频率越高，衰减率越大，不利于电磁波的传播；通过特性曲线与井下实验数据相比较得出在900MHz左右为井下无线通信系统传输信号最佳频段。

Xviii, xxxv, lii, lix, lxix, cix, cxxxvii (xvii, xxxiv, li, lviii, lxviii, cviii, cxxxvi), those national anthems so full of love of Israel and almost startling in their hatred of the foes of Jahweh and of Israel, if read from the viewpoint of the writers, are sublime, vivid, glowing, enthusiastic, though exaggerated, poetic outbursts, instances of a "higher seriousness and a higher truthfulness", such as Aristotle never would have found ina song of Babylonia or of Sumeria.

十八，三十五，吕，柳， lxix ，捷达夥伴， cxxxvii （十七，三十四，李鹏， lviii ， lxviii ， cviii ， cxxxvi ），国歌，使这些充满爱心的以色列，几乎惊人的仇恨敌人Jahweh和以色列，如果读取的观点作家，是崇高的，生动的，光辉，热情，虽然有些夸张，富有诗意的爆发，情况是"更高的严肃性和较高的真实性"，如亚里士多德永远会发现那首歌的东风或

Compared with the blank controls, aldrin at concentrations higher than 80 μg/L decreased life expectancy at birth and net reproduction rate of maternal generation of the cladoceran, and that at concentrations higher than 160 μg/L shortened generation time and decreased intrinsic rate of population growth.

与空白对照组相比，浓度高于80μg/L的艾氏剂使多刺裸腹溞母代的生命期望和净生殖率显著降低；浓度高于160μg/L的艾氏剂使母代的世代时间显著缩短，种群内禀增长率显著降低。

Although in 1998 the government passed the Urban Renewal Ordinance, certain revisions to the Ordinance and increasing the carrying capacity to encourage private investment, resulted in the construction industry passing over the clapped-out apartment that were in actual need of reconstruction in favor of developing higher carrying capacity and higher land price for more commercial purposes.

政府虽然於1998年颁布都市更新条例，并经几次修正，并以建筑容积加成等诱因奖励民间投资办理更新，但业者仍以市场商机为导向，偏好高容积、高地价地段的住商社区更新，真正需要更新的老旧住宅社区反而遥遥无期。

The comparative tests of the rheological properties between Alcalase induced soy coagulum and Magnesium Chloride/Calcium Chloride induced soy coagulum shows that the former one has higher hardness,lower strength,and 10 times higher adhesiveness of the latter one.

对Alcalase与盐类凝固剂氯化镁和氯化钙凝固豆乳的主要流变学性质比较发现，Alcalase凝固豆乳的硬度比盐类凝固剂大，凝胶强度比盐类凝固剂低，粘附性比盐类凝固剂高10倍以上，使凝胶较粘，乳清不易排出。
