Results There were statistical significances between Group A and B on the incidence rate of the chylothorax after operation(A:1/45;B:9/92,P＝0.03), thoracic drainage within 48 h(the first 24 h:A:254.33 ml±45.15 ml,B:493.61 ml±76.67 ml;the second 24 h:A:141.11 ml±25.53 ml,B:323.39 ml±58.17 ml;P＜0.05),the decannulation rate within 3 days (A:94.78%;B:62.21%,P=0.001),complication(A:3/45; B:0/92, P=0.034) and cancer metastasis of supraclavicular lymph nodes (A:0/45;B:9/92,P=0.03) by follow-up.

结果 两组患者在术后乳糜胸发生率(A：1/45；B：9/92，P=0.03)、术后48 h胸腔引流量〔第1个24 h：A：(254.33±45.15)ml，B：(493.61±76.67)ml；第2个24 h：A：(141.11±25.53)ml，B：(323.39±58.17)ml；P＜0.05〕、3天内拨管率(A：94.78％；B：62.21％，P=0.001)、并发症(A：3/45，B：0/92，P=0.034)以及随访锁骨上淋巴结转移(A：0/45，B：9/92，P=0.03)等方面有统计学意义。

Roller sprockets have some special dentiform teeth.Depending upon the meshing which lies in between chain teeth and chain nodes,it can transfer the desired movement.

滚子链轮上制有特殊齿形的齿，依靠链轮轮齿与链节的啮合来传递运动和动力。

AIM: To investigate the effect of PD98059, a specific repressor of extracellular signal regulated kinase1/2 (ERK1/2), on the proliferation of the murine lymphocytes. METHODS: Lymphocytes were isolated from lymphoid nodes of BALB/c mouse. After stained with carboxy fluorescein diacetate, succinimidyl ester, the cells were stimulated with polyclonal activators, concanavalin and phorbol 12,13 dibutyrate plus ionomycin.

分离小鼠淋巴结细胞，藉羧基荧光素乙酰乙酸染色，用多克隆刺激剂刀豆A蛋白或者佛波醇酯加离子霉素刺激，以流式细胞术分析PD98059对淋巴细胞增殖的影响；利用碘化丙锭染色分析PD98059对细胞周期的影响。

A programm is designed to calculate nodes of quadric curve by straigh approaching with equalstep length and dimidiate method,thus N/C machining operation program can form automatically.

在一定误差范围内，采用等步长直线逼近法和二分法对二次曲线进行数学计算处理，利用 VisuaL Basic 6。

Stem nodes swollen. Stipules interpetiolar, sheathing terminal bud, caducous. Leaves simple, opposite or distichous, petiolate; leaf blade leathery, usually glabrous, margin entire, serrulate near apex, or completely serrulate.

茎节膨大。托叶在叶柄间，具顶芽鞘，早落；单叶，相反或，具叶柄；革质的叶片，通常无毛，边缘全缘，有细锯齿近先端，完全有细锯齿的或。

In this paper, a Multiple Ant Colony based Routing Algorithm is proposed for routing optimization designing, in which the communication messages sent by nodes for searching the optimal route are treated as ants with limited life-span. Through the ants' movement and Populations' cooperation, the main routing path and multiple candidate routing paths can be distributedly obtained.

提出了一种基于多蚁群无线传感器网络路由算法，采用多种群并行搜索，并在种群中采用基于目标函数值得启发式信息素分配策略和根据目标函数自动调整蚂蚁搜索路径，利用蚁群的分布式特点，通过有限寿命蚂蚁的协作在源节点与目的节点之间的运动获取主路径和备选路径，然后根据节点信息适时更新路由表。

Such a problem seldom happens in DONet, as the loads of the nodes are evenly distributed and delivering paths are dynamically set according to data availability.

此类问题很少发生在DONet上，因为节点的负载是均匀分布的，而分发的路径也是根据数据有效性来动态设定的。

Scalability : As we have developed an automatic command dispatching and report collecting system, it is easy to launch the DONet program to more nodes if needed.

可伸缩性：由于我们开发了自动命令分发和报告收集系统，使得发布DONet程序到更多节点变得容易。

Our experiments, involving almost all active PlanetLab nodes, demonstrated that DONet delivers quite good playback quality even under formidable network conditions.

我们的实验设计几乎所有活跃的PlanetLab节点，证明DONet即使在恶劣的网络环境下也能做到高质量的回放。

From here, we will rename some of the nodes and transitions to make the process more readable. To do this, click on the node and the name will become enterable, or double click and use the dialog to enter the new name.

单击节点选中它，再单击一次，就可以重命名此节点；或者双击节点，在弹出的对话框中也可以重命名节点；或者在屏幕下方的属性窗口重新指定名称。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。

The relationship between communicative competence and grammar teaching should be that of the ends and the means.

交际能力和语法的关系应该是目标与途径的关系。
