无结构的

People concentrated on more morphology respects to the research of the lamprey for a long time, but the research of genomics and even Proteomics is a blank.

由于其一般结构甚为原始，在脊椎动物进化史上代表着动物已进入有头、有雏形脊椎骨，但还无上、下颌这一发展水平，故在进化史上占有特殊地位，是现存的一类最原始的无颌类脊椎动物。

The evident damage of chloroplast ultrastructure in S.polyrrihiza appeared at pH 2.5, but no severe plasmolysis and chloroplast swelling were seen.

This paper studies reprinting/reposting relationships among online news outlets based on complex network theory and related measures. We analyze the topological structure of undirected unweighted reprinting/reposting network as well as its undirected weighted and directed variations.

基于网络新闻媒体之间的转载关系构建了新闻转载网络，应用复杂网络理论分别研究了其无向无权网络、无向加权网络以及有向网络的拓扑结构。

The results, which show that discharge coefficient is determined by inflow structure of RFD and Cp is linear with K when RFD's structure parameter is constant, will promote the development of RFD's fluid dynamics model.

结果表明：流量系数Cd与可逆流体换向装置的入流结构形式有关；当RFD的结构参数恒定时，压能转换系数与无因次参数K呈线性关系。

Results The TCD manifestations of patients with semicoma have no characteristic change.

结果 浅昏迷患者的TCD表现无特征性改变，当出现中度昏迷或深昏迷时，颅内幕上结构损害患者TCD表现与文献报告相似，颅内幕下结构损害、代谢及弥漫性脑病患者大脑中动脉血流速度改变不明显，但死亡的18例病人中有13例出现了收缩期末血流速低于舒张期末血流速。

Results The TCD manifestations of patients with semicoma have no characteristic change. In moderate or deep coma patients, who have intracranial supratentorial injury, the TCD manifestations are similar to related documents. The blood flow velocity of middle cerebral artery of patients with subtentorial brain injury or metabolic or diffused brain diseases have no obvious change. But in the 18 dead cases, there are 13 whose blood fiow velocity of end systolic stage are lower than those of end diastolic stage.
