Experts said the study doesn ' t mean children need to be on treadmills or in soccer leagues ? they just need to be able to run around and play physically , even for short bursts of time 专家说，这项研究并不是指儿童必须踏上跑步机运动或加入足球联盟?他们只要跑来跑去、从事体能性质的游戏即可，甚至一小段时间也行。
Possession is important , so a slow tempo , short passing game should be employed for most of the match , but the manager should be willing to tweak to a higher tempo for short bursts to create chances if none seem forthcoming 控球很重要，所以慢节奏，短传战术应该对大部分比赛都适用，而经理可以在达不到预期情况下，短时间突然加快节奏以寻求突破。
These ultrasonic oscillations may be continuous , but in most cases they are short bursts of ultrasonic energy , stimulated by various amplitude peaks of the audible signal , and dying out quickly , but recurring frequently 这些超声波震荡可能是连续的，但大多数情况下，它是由可听范围信号电平的不同峰值激励产生的一些超声能量的短脉冲，很快消退但频繁的出现。
While aerobic distance work should be a primary training focus , an aerobic training and speed training will improve your performance times since they enable you to function at higher intensities and to endure high lactic acid levels ( a by - product of short bursts of exercise ) 有氧跑步是训练的主要项目，有氧训练和速度训练将增加你的运动次数，因为他们可以使你的身体器官在更高强度运动下正常运作，并能忍受肌肉中的高乳酸（短期剧烈运动的副产品） 。
The paper discusses the part of asic design of tcm ( trellis coded modulation ) in hdtv 8vsb terrestrial channel broadcasting receiver chip . in testing , the tcm can improve the signal - to - noise by 3 . 3db compared with uncoded 4 - vsb modulation , and with the 12 path intrasegment interleaving in tcm coding and viterbi decoding , system can control short burst noise error efficiently 在高清晰度电视信道接收芯片中内码是8 ? vsb的格状编码，在系统性能上使用tcm编码要比未编码有3 . 3db的编码增益，另外在格状编码中加入了12路的内交织，可有效的抑制短的突发噪声对接收端viterbi解码性能的影响。
