无环的

To describe the Product Structure, 3D XML defines a lightweight Directed Acyclic Graph that makes intensive use of references and instances.

为了描述产品结构，3D XML 定义了轻量级的有向无环图，来集约地利用了参引与实例。

The model of the embedded system was constructed by directed acyclic graph to obtain the objective function for hardware/software partitioning.

首先，使用有向无环图对嵌入式系统建模，得到软硬件划分优化系统的目标函数。

As the graph of Bayesian network is required to be a directed acyclic graph, which was changed during the constructing process, checking for cycle is need in the interaction.

由于贝叶斯网的网络结构要求为一有向无环图，并且此图在交互建网过程中时刻变化，所以要在交互过程中反复检测环路是否存在。

Finally, an interesting result about the total acyclic join dependencies is given.

最后给出了一个关于全无环连接依赖的有趣结果。

A universal algorithm for detecting all simple paths between any two nodes in weighted directed acyclic network was presented.

提出了一种有向无环网络中任意两节点间所有简单路径的通用搜索算法。

GO is a set of dynamic controlled vocabulary, its structure is DAG.

基因本体是一套具有动态形式的控制词汇，其结构为有向无环图。

For the feature that Bayesian network is required to be a DAG, this algorithm can also be used in network structure learning.

此外针对贝叶斯网为有向无环图这一特点，此算法还可以应用于网络结构学习的过程中。

Objective To evaluate the role of acyclovir in treatment and prevention of herpes simplex keratitis.

目的观察无环鸟苷对HSV-1角膜炎的治疗和预防复发作用。

In this article, high-pure lactic acid and ethanol acid were used to synthesized PLGA by direct condensation polymerization, and zinc octanoate of low nocuity was used as katalyst, instead of stannous octanoate to synthesize PLGA by the way of opening ring.

本文首次采用高纯度乳酸、乙醇酸直接缩聚合成无催化剂的端羧基PLGA，并分别采用了低毒性辛酸锌代替辛酸亚锡为催化剂通过开环聚合法合成端羧基／酯封端PLGA。

He was treated empirically with acyclovir, and multiple blood and CSF cultures were negative.

他在接受经验性的无环鸟苷治疗后，多次血培养和脑脊液培养是阴性。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
