The Study of the CZB Measuring System for Phase-Noise Spectrum

相关零拍法相位噪声谱测量系统的研究与实现

Type CZB-C Automatic Protector ( CZB for short ) is used in various diesel engine products and generating sets .

CBZ-C型柴油机自动保护器（简称CZB）主要用于柴油机及电站机组的自动保护。

But in CZB medium , 72.3 % embryos prevented the 2-cell block and finally 17 % embryos reached blastocyst .

但在CZB培养液中，有723%能发育通过2-细胞期，并有17%到达囊胚。

In this study , the CZB medium was used to culture IVF embryos of KM strain mouse , A practical new method of culturing mouse embryos was established .

本研究首次将CZB培养液应用于昆明小鼠早期胚胎的培养，建立了一个可行的胚胎体外培养的新方法。

The cleavage rates of reconstructed embryos in M 16 , M 199 and improved CZB medium were 9.09 % , 16.17 % , 17.05 % , respectively .

M16、M199和改良的CZB培养重组胚胎，卵裂率分别是9.09%、16.17%、17.05%。

Cleavage rate of mouse early embryo that were co-cultured with cattle fallopian tubes epithelium in CZB medium increased significantly in comparison with the control without epithelium ( P0.05 ) .

小鼠早期胚胎在CZB和牛输卵管上皮细胞（COEC）共培养体系中的卵裂率较对照组明显提高（P0.05）

When the engine speed , oil pressure , oil temperature and water temperature exceed the specified limit values , CZB will make the engine stop , and at the same time give sound and light warnings .

当柴油机的转速、油压、油温及水温超过规定的极限时，CZB能使柴油机停车，并发出声、光报警信号。

CZB medium was used as a base medium to study the function of taurine , glucose and porcine oviductal epithelial cells system in the culture of blastomeres isolated from mouse 4 ? 8-cell embryos .

以CZB为基础培养液，培养小鼠4、8-细胞胚胎单卵裂球，研究葡萄糖、牛磺酸和猪输卵管上皮细胞共培养在其体外发育中的作用。

The objective of this study was to test this hypothesis . Newly ovulated mouse oocytes were cultured in the CZB medium supplemented with different concentrations of pyruvate before treated for activation or assayed for MPF activity .

为了验证这个猜测，我们将新排卵的小鼠卵母细胞培养在添加不同浓度丙酮酸的CZB中，然后进行激活处理或通过放射自显影的方法分析MPF活性。

Both CZB and HTF medium could overcome development retardation at 2-cell , resulting in greater cleavage rate and blastocyst rate in comparison with M_ ( 16 ) and BWW medium ( P < 0.01 ) .

CZB和HTF培养液能有效地克服小鼠胚胎的2-细胞发育阻滞，与M16和BWW相比，2-细胞卵裂率和囊胚率均存在显著性差异（P<0.01）；

Due to the difficulty that the traditional zero-beat method will be faced with in the aspect of improvement of measure sensitivity of the phase-noise spectrum , a new type measure method named correlation - zero-beat method ( CZB ) is put forward .

针对传统零拍测量法在提高相位噪声谱测量灵敏度方面所面临的困难，实现了一种利用相关技术原理结合零拍法的测量新方法&相关零拍测量法。

1-cell mouse embryos were cultured to blastocyst , expanding blastocyst stage in vitro by adding exogenous oxidant & H_2O_2 to CZB medium in different developing periods , therefore , the number and the relative length of chromosomes can be observed .

在体外CZB培养的不同时期添加外源性ROS，胚胎发育至囊胚、扩张囊胚阶段，观察其染色体数目和染色体相对长度。

Addition of glucose in CZB had a significant effect on the blastocyst rate of blastomeres isolated from mouse 4 , 8-cell embryos ( 29 % vs 36 % and 14 % vs 19 % ) ( P < 0.05 ) .

添加葡萄糖后，4、8-细胞胚胎单卵裂球的囊胚发育率分别为36%和19%，有显著提高（P<0.05）。

There were no significant different among them ( P0.05 ) . The highest blastocyst rate was CZB ( 32.5 % ), the lowest was M199 ( 12.3 % ), and the KSOM ( 27.2 % ) was the middle among them .

在囊胚率发育方面，以CZB组为最高（32.5%），而M199组（12.3%）最低，两者间存在显著差异（P0.05）。

Methods : At the CO 2 levels of 5 % ( control group ), 5.7 % , 6.0 % and 15 % , embryos were incubated in drops with CZB medium , and the drops were covered by paraffin oil which was treated with three distilled water .

方法：获取小鼠2-细胞胚胎，置于CZB培养液微滴，覆盖经三蒸水处理的石蜡油，分别在5%CO2（对照组）、5.7%CO2、6.0%CO2和15%CO2浓度下体外培养；
