无连接方式

Therefore Internet news service can"t meet today"s demands of social development. Though there are some achievements to carry on research at present, the service has not met readers" real demand.The research of news " anthropomorphize at home is at the stage of exploration . Though some units have carried on some research and made some achievements, various kinds of defects exist in these achievements on the whole.

目前的网络新闻服务站点基本上是基于B/S结构的单一的新闻发布系统，而HTML页面技术和HTTP无状态连接协议，没法提供跨媒体的多样化内容的服务，不适于用户按照自己的习惯进行阅读和订购，因而使得Internet新闻服务尚没有摆脱传统的推送服务方式，这已经越来越不满足现在社会发展的需求。

In the rhombohedron, each top site is occupied by a pair of ligand-unsupported Ag atoms which are surrounded by six phenol groups in an ethane-like structure. The phenol groups at another ends of the ligands bridge the rhombohedrons into novel non-interpenetrating three-dimensional network.

在每个棱柱体内，每个顶点由无桥连配体支持的、周围的六个酚羟基以一种不寻常的、类似于乙烷分子结构的扭曲方式排列的一对 Ag 原子占据，配体另一端酚羟基将棱面体连接成新颖的非穿插的具有棱形通道(沿 a 和 b 轴方向)的三维网络结构。

Especially, when local fans are unwatched, it will bring coal mine potential safety hazard.

目前，对于3.3kV供电的高产高效综合机械化采煤工作面，根据采煤方法的要求，与其配套的掘进方式是三条巷道同时推进，共需六台对旋式局部风机进行掘进通风，三台运行，三台备用，由于设备数量多、占地面积大、连接复杂，故障率较高，频繁引起巷道内"无计划"停电停风，造成瓦斯积聚，特别是在无人值守时，很容易给煤矿的安全生产带来重大隐患。

The neurons differentiated by NGF in cultured PC12 cells can divide in amitotic way.The differentiated neuron can form junction by cell migration, neurite extension or cytoplasmic bridge.

NGF诱导PC12细胞分化的神经细胞能以无丝分裂方式增殖；分化神经元可以通过细胞迁徙、突起延伸及共同胞质桥等方式相连接。

The novel device integrates two important microfluidic phenomena, including hydrodynamic focusing and valveless flow switching inside multi-ported micro-channels. In this study, a simple theoretical model based on "flow-rate-ratio" method is first proposed to predict the performance of the device. Based on these data, a pre-focused 1xN flow switch is designed and fabricated using micromachining techniques.

本专题中的微流体晶片同时涵括了以下两种很重要的微流体现象--(1)水力预集中（hydrodynamic pre-focused ）以及(2)无阀式开关的切换方式，并在同一平面上作流向控制，以便将相同样品注射至不同或相同之出口槽(output-port)以连接至不同的微流体分析晶片，以达成多功能连续式的样品进料功能。

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。
