The slight difference in response time of1 msec would not be perceivable, and is likely due to measurement variability. 响应时间的差异只有1msec,可以无需考虑,而且可能是由于测量的误差引起的。
A quasi period pulsation cluster with the average period of 37 msec was found in the microwave burst on Nov.2, 1997. For magnetoacoustic MHD oscillations of dense flux tubes, it can be deduced that the radius of the loops is about 90 km. 我们在1997年11月2日的爆发中发现平均周期为数十ms的准周期振荡群。在高密度流管的磁声波MHD振荡条件下,可取得磁环半径约90公里的结果。
The control method solves the view field variation of each optical channel in its measurement period and ensures identity of 20 optical channels of ATPS in the scan measurement minor frame period of 100 msec. 解决了扫描测量过程中光学通道在其测量周期内视场的变化,保证了各测量通道的空间同一性。
The duration of the bursts was 2-9 msec and might reach 13 msec. 放电持续时间为2&9毫秒,个别单位可达13毫秒。
After a prime showing on the monitor for 100 msec, a target replaced it and lasted for 400 msec. 启动刺激的呈现时间是100毫秒,随后是目标刺激400毫秒。
Conclusion MSeC can effectively increase the content of selenium, GPx activity and GAP-43 expression in tissues of chick embryos brain, but selenium supplementation don't affect ID ⅱ activities in brain. 结论MSeC可有效提高鸡胚脑组织硒水平、脑GPx活性和GAP-43的表达,对脑IDⅡ活性没有影响。
Comparison with the experimentally observed life time-100 msec, the recombination time 900 fsec is quite short. 这一现象与实验观察到的短寿命光诱致吸收峰结果相似,但在时间上900fsec短于实验的100msec。
Results MSeC increased the content of selenium, activities of GPx and the expression of GAP-43 in chick embryos brain. MSeC dosage correlated well with the selenium concentration and GPx activities in brain ( P < 0.01), but not with the ID ⅱ activities in brain. 结果对正常鸡胚补硒,可提高脑硒水平、脑GPx活性及GAP-43的表达,补硒量与脑硒、脑GPx活性显著相关(P<0.01),而与脑IDⅡ活性无相关性。
As the syllable duration was made shorter than 8-13 msec, vowel identification became impossible. 当音节短至8&13毫秒时,元音即不能被识别。
Internet Engineering Task Force ( IETF) proposed the multicast security architecture and multicast security ( MSEC) group key management architecture. But there is not a security multicast scheme, which is based the above architectures and the actual network deployment and key management algorithm. IETF提出了组播安全参考架构和组密钥管理架构,但在该架构下,尚无能够面向实际网络部署的安全组播方案及相应的密钥管理与协商算法。
