The tumor was squamose carcinoma confirmed by histopathological examination. The culture system in this study provided a potential tool for studying the molecular mechanism of carcinogenesis of human bronchial epithelial cells induced by BPDE.

The content increase of 8-OH-dG was in accordance with the progress of cell carcinogenesis, which was displayed in human bronchial epithelial cells induced by BPDE and NiS.

在体外用BPDE和NiS作用于人支气管上皮细胞系诱导其转化和癌变过程中，8OH dG出现于细胞转化之前，其含量的增加与细胞癌变进程相一致。

Conclusions Anti-BPDE can result in DNA strand breakage, and the degrees of damage is related to the administrated doses of anti BPDE.

结论反式BPDE可导致DNA断裂损伤，其损伤程度与剂量有一定关系。

Business Process Definition Meta-Model ( BPDM).

业务过程定义元模型（BPDM）。

Like BPDM, ODM is not yet a standard.

与BPDM类似，ODM也还没有成为一个标准。

Although BPDM is not new, it is still being discussed internally without an official release.

尽管BPDM不是新东西，但它依旧还处于内部讨论阶段，没有正式发布。

Mostly, BPDM should include a model for expressing business processes and a file format.

通常，BPDM应该包括表示业务过程的模型和一个文件格式。

A tree is created and maintained by the switch for every VLAN according to the mark affiliated in BPDU. It can cut down the delay from the block state to transmitting state obviously and improve the real-time characteristic in the Ethernet.

在BPDU中加入标示性能的标志，交换机根据这个标志为每个VLAN生成、维护一个稳定的树结构，使交换机端口由阻止状态到转发状态的延迟明显缩短，提高了网络的实时特性。

In the same condition, testing shows that this self-adaptive-interval sending BPDU data-package algorithm spends network bandwidth more reasonably and reduces the convergent-time more effectively.

测试表明在其他条件相同的情况下，该自适应时间间隔发送BP-DU数据包算法比定时发送BPDU数据包更合理地利用了网络带宽，更有效地减小了收敛时间。

However, according to the standard of 802.1D, it is impossible to forward BPDU segment with VLAN TAG.

然而，按照802.1D标准BPDU不带VLAN tag，而且要求所有网桥不能转发BPDU；

BPDU and network management messages are processed.

BPDU和网络管理消息仍将被处理。

The effect of E.coli endotoxin and the protective action of anisodamine ( 654-2) on the bovine pulmonary endothelial cell ( BPEC) in vitro were investigated.

作者研究了精制大肠杆菌内毒素对体外培养的小牛肺血管内皮细胞的影响及654-2的保护作用。

The cluster set generated by BPEC is proved to be a Maximum Independent Set, which can cover all network nodes.

由BPEC算法产生的簇头集合被证明是一个最大独立集，簇头集合能覆盖网络的所有节点。
