丹佛智能发育筛选检查（DDST）在国内的应用：回顾与瞻望

The results showed that the DDST abnormal rate of severe iodine deficiency group was obviously higher than that mild and control group ;

卡方值检验表明，在P＝0.05水平上，重度缺碘组的DDST可疑和异常比率都显著高于轻度缺碘组和正常组；

Both groups were given NBNA examination before and after treatment ( mean interval was 12 days ), also given DDST examination for follow-up .

两组治疗前后行NBNA检查（平均间隔12d），并用丹佛发育筛查法进行随访。

And the performance of TDM , ST and DDST is compared by training sequence selection , channel estimation MSE , data detection BER and system throughput .

论文从训练序列选择，信道估计性能，信道容量以及信号检测误码率和系统吞吐率等方面比较了TDM，ST和DDST的性能。

The improved DDST intelligence examination was done on 67 cases of endemic cretinism in Qinghai through random sampling and had got developmental quotient ( DQ ) .

通过随机抽样对青海省67例地克病患者做改进后的DDST智能检查，取得发育商。

Methods The extended spectrum β - lactamase-producing Klebsiella pneumoniae ( ESBL-KP ) spp. were screened out by the double disc synergy test ( DDST );

方法以双纸片协同试验（DDST）筛选出产超广谱β内酰胺酶肺炎克雷伯菌（ESBLKP）；

Methods Bacterium identification and antimicrobial susceptibility were tested by WalkAway-40 full automated microbial analytic instrument and the producing of metallo - β - lactamases ( MBLs ) was detected by double-disk synergy test ( DDST ) .

方法细菌鉴定、药敏实验采用WalkAway-40全自动微生物分析仪，金属β-内酰胺酶检测采用双纸片增效法。

Analysis and simulation results show that the optimal power of DDST training sequences is independent of SNR and whether the DDS removal algorithm is employed . Finally , the channel capacity lower bounds of ST and DDST schemes are derived when optimal training power is employed .

研究结果表明，DDST训练序列的最优功率与信噪比无关，与是否采用DDS消除算法无关与信道增益也无关。论文最后给出了ST和DDST系统训练序列功率最优时，信道容量下界的表达式。
