分组

Security is the most important principle of block cipher design.

安全性是分组密码最重要的设计准则。

Methods Randomized block design was used in this study. A total of 74 subjects were enrolled.

共入选74例患者，采用随机分组的方法，先分层，然后随机分为两组。

The cryptanalysis and design of block ciphers are one of the hotspots in modern cryptography.

分组密码的设计与分析是当前密码学研究的热点课题之一。

Autonomy is a notable feature of information security. So it's very necessary to conduct block cipher research, design and development relying on our own ability, and absorbing advanced experience at the same time.

自主性是信息安全的一个重要特点，在我国，依靠自己的力量并汲取现有的先进经验进行分组密码的研究、设计和开发也是非常必要的。

Methods 50 cases were divided randomly into a CSEA group and a continuous epidural anesthesia group, with 25 cases in each. Then their BP, SpO2, ECG, HR, the time of block analgesia, muscle relaxation, neonatal Apgar score, and side effect were observed and recorded.

对50例需急诊剖宫产无妊娠合并症的产妇随机分组施行腰麻－硬膜外联合麻醉和硬膜外麻，每组25例，监测并记录BP、SpO2、EKG、HR，麻醉起效时间，麻醉阻滞效果，脊神经阻滞上界平面时间，新生儿Apgar评分及不良反应。

Methods Detect the prothrombin time,activated partial thromboplastin time, fibrinogenand thrombin timein 31 cases normal person, 35 cases diabetes mellitusand 32 cases diabetic retinopathypatients with Sysmex CA-1500 automated blood coagulation analyzer, data grouping and treatment with analysis of variance.

用日本东亚CA1500全自动血凝仪对31例正常对照组，35例单纯糖尿病组及32例糖尿病视网膜病变组的凝血酶原时间、活化部分凝血酶时间、纤维蛋白原、凝血酶时间时行检测，并分组比较。

By using Borda method, we can carry...

最后，再在分组之间采用加权Borda数法进行最终的排序。

A first packet is broadcast from a first network device to other network devices that participate in the network.

从第一网络设备向参加网络的其它网络设备广播第一分组。

This character results in increase of packet lost rate and queuing delay of buffer system.

这种特性会导致分组丢失率增大和缓存系统排队延时的增加。

With packet switching, the communications capacity of a network can be increased by a factor of 100 or more.

由于 使用分组交换技术，网络的通信能力提高了100倍甚至更多。数字网络的倍甚至更多。

I am accused of being overreligious," she said in her quiet, frank manner,"but that does not prevent me thinking the children very cruel who obstinately commit such suicide.""

客人们在卡罗利娜·埃凯家里，举止就文雅一些，因为卡罗利娜的母亲治家很严厉。
