Regular formation of globular compact embryogenic callus with bipolar shaft and somatic embryos with diminutive cotyledons (Plate Ⅰ a~d) was induced from immature peanut embryos in induction media containing 2,4 D (Tables 1, 2). More somatic embryos were also formed during their subculture (Fig.2). Light substantially suppressed embryogenesis, a phenomenon similar to that observed under in vivo conditions. (Fig.3). In media for maturation, somatic embryos developed root and shoot apexes up to an...

Regular formation of globular compact embryogenic callus with bipolar shaft and somatic embryos with diminutive cotyledons (Plate Ⅰ a~d) was induced from immature peanut embryos in induction media containing 2,4 D (Tables 1, 2). More somatic embryos were also formed during their subculture (Fig.2). Light substantially suppressed embryogenesis, a phenomenon similar to that observed under in vivo conditions. (Fig.3). In media for maturation, somatic embryos developed root and shoot apexes up to an advanced stage (Plate Ⅰ e~g). Somatic embryos with roots and shoots gave rise to plantlets in medium for regeneration under light (Plate Ⅰ h). The plantlets were then transferred into pots containing sand soil mixture and grew there healthily (Plate Ⅰ i), and eventually bore peanut pegs (Plate Ⅰ j). Appropriate combination of factors such as light intensity (Fig.3), length of immature embryos, 2,4 D concentration, treatment of cotyledons and inoculation density (Fig.1) brought about embryogenesis at 75% or higher percentage and more than 3.0 somatic embryos per cotyledon could be formed (Figs.1~3). Because of its similarity to zygotic embryo and high efficiency, the in vitro system is deemed a satisfactory system to be used as a receptor in genetic transformation and for embryo development research.

Formation control and path planning of multiple mobile robots are combined in a reasonable way. Formation model and the concept of keeping formation are put forward. This path planning is based on behavior-based navigation algorithm, and the movement course of robot team is divided into normal movement phase, obstacle avoidance phase and formation recovery phase. In order to maintain formation, virtual robot is introduced into obstacle avoidance phase. If formation is destroyed severely, robots search local...

Formation control and path planning of multiple mobile robots are combined in a reasonable way. Formation model and the concept of keeping formation are put forward. This path planning is based on behavior-based navigation algorithm, and the movement course of robot team is divided into normal movement phase, obstacle avoidance phase and formation recovery phase. In order to maintain formation, virtual robot is introduced into obstacle avoidance phase. If formation is destroyed severely, robots search local goal configurations according to path planning algorithm. By this control method, multiple mobile robots can avoid obstacles safely and keep in regular formation.

将多移动机器人的运动控制和路径规划有机结合,提出了多移动机器人的队形模型和保持队形的定义.在此基础上,以基于行为的导航算法为基础,将机器人队列的运动过程划分为正常运动、避障和恢复队形3个阶段.在避障阶段,引入虚拟机器人使队形保持部分完整;当队形被严重打乱时,规划机器人的局部目标位姿使队列快速恢复队形.仿真实验表明,该控制方法不仅使多移动机器人安全避障,而且队形保持较完好.

Objective To investigate differences between benign and malignant superficial enlarged lymph nodes with two-dimensional and Doppler ultrasonography, and to evaluate its clinical application. Methods Two hundred and thirteen enlarged lymph nodes of ninety-eight patients were divided into benign and malignant groups. The size, morphology, echo and blood flow dynamic parameters of the lymph nodes were observed, and the characteristics of superficial enlarged lymph nodes resulting from different pathogenesis was...

Objective To investigate differences between benign and malignant superficial enlarged lymph nodes with two-dimensional and Doppler ultrasonography, and to evaluate its clinical application. Methods Two hundred and thirteen enlarged lymph nodes of ninety-eight patients were divided into benign and malignant groups. The size, morphology, echo and blood flow dynamic parameters of the lymph nodes were observed, and the characteristics of superficial enlarged lymph nodes resulting from different pathogenesis was analysed. Results Compared with benign group, a larger cross section, rounder shape was observed in malignant group. The distribution of benign group showed small branch blood flow, regular formation and low-resistant spectrum, and the distribution of malignant group showed malposition, deformation disorder and high-resistant spectrum. Conclusion Ultrasonography is a preferable method in diagnosis of superficial enlarged lymph nodes.

目的探讨良、恶性浅表肿大淋巴结声像图及多普勒血流参数变化特征,评价超声诊断技术的临床应用价值。方法98例213枚肿大淋巴结分为良、恶性两组,采用高频探头观察肿大淋巴结的形态、大小、内部回声及血流动力学指标。并结合病理,分析不同病因浅表肿大淋巴结的超声特征。结果恶性淋巴结横径、形态更接近圆形,多融合,其周边型血流明显高于良性淋巴结(P<0.05),良性肿大淋巴结血流分支细少,走行规律,呈低阻力;恶性呈高阻力,为不规则扭曲、紊乱血流。结论超声在浅表肿大淋巴结定性诊断中可为临床提供更多诊断信息,为影像学首选诊断方法。
