From the view of supported data security protocols , although the MSEC protocols profess to be extensible , currently they mainly support ESP and AH protocols , which work on the IP layer .

在所支持的数据安全协议方面，MSEC协议簇虽然声称是可扩展的，但从已经支持的协议看，主要是ESP和AH协议，其工作于网络层。

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。

T was about 150 msec .

T约为150毫秒。

Methods Normal chick embryos of 8 days old were injected with MSeC of different concentrations ( containing 0 , 1 , 5 , 10 , 20 , or 40 μ g selenium ), and were sacrificed on the 20th day .

方法对孵育8d的鸡胚分别注射不同剂量的MSeC（含0、1、5、10、20、40μg硒），孵育至第20天时处死。

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。

Methods A total of 2 240 patients with unwanted hair were treated by long-pulsed Alexandrite laser ( wavelength : 755 nm , 20 msec pulsewidth , 10 mm spot size ) . Results We found that there was different percentage of depilation in different part .

方法使用翠绿宝石长脉冲激光（波长755nm，脉宽20ms，光斑直径10mm）对2240例患者进行脱毛治疗，治疗能量15~25J/cm2，两次治疗间隔1~4个月。

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。

In α _p not exceeding 30 μ V , an earlier ( 15 20 msec peak latency ) and a later ( 20 28 msec peak latency ) portion can be shown to be more sensitive to the long and to the short wavelength spectral lights respectively .

在不超过30μV振幅的αp波中，可以分辨出一个峰潜伏期约1520毫秒和一个峰潜伏期约2028毫秒的部分，它们分别对长波段和对短波段的光较为敏感。

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 .
