dBv

Taking benefits of Germany DBV standards, It studies the hybrid effects of flexural strength and toughness of steel-synthetic fiber, so does the splitting strength and toughness. It develops the primary analysis of the shear toughness of HFC in energy approach.

参照德国DBV标准计算和评价了不同纤维掺量组合时混杂纤维混凝土的弯曲强度和韧性、劈拉强度和韧性，使用能量法对混杂纤维混凝土的剪切韧性作了初步分析。

By analyzing multi-version database model ( called DBV) and CSCW ( Computer Supported Cooperative Work), some limitations on DBV are put forward in order to use it in CSCW. Then it is described how to create CSCW work model by using DBV technology.

通过对多版本数据库模型（DBV方法）和CSCW（计算机支持的协同工作）的分析比较，提出了面向CSCW的DBV方法的限制策略，描述了如何利用多版本数据库技术构造一个CSCW工作模型。

Using DBV to create CSCW working model

利用DBV构造CSCW工作模型

There is a linear relationship between the average dilution and dimensionless downstream distance; DBV jet has better effect of dilution as compared with the round jet of the same nominal diameter in coflows under the same volume of discharge.

平均稀释度和无量纲的沿程距离之间存在线性关系，相比于具有相同名义直径的同向流动环境中的圆射流，在相同排放流量条件下，DBV射流具有更好的稀释效果。

In order to apply the DBV approach in automatic examination system supported by computer, we make some restriction on DBV approach, then describe the method how to apply DBV approach in this system.

为了在计算机自动化考试系统中应用DBV方法，我们对DBV作了一些限制，然后描述了它的具体实施。

And the changes of circulatory blood volume ( CBV) and dynamic blood viscosity ( DBV) were also investigated.
