查询词典 mating

A new type mating device is designed which has a cupule at each end of manipulator. Kinematics analysis, structural design of mating device and motion equations are also given in this paper. At the same time, the motion of manipulators position and posture are analyzed according to the auto-mating tactic.

本文进行了基于吸盘结构的水下运载器主动对接装置的结构设计，对装置进行了运动学分析，结合机械手的实际结构，推导出机械手末端吸盘的运动方程，并根据主动对接作业策略进行了机械手位姿变化的分析。

When male mated consecutively in a night, mating interval, duration for mating, each mounting, intromission and the last mount, and copulatory mass kept constant, suggesting that male possess a pattern of constant mating investment, which might result from intense sperm competition in this species.

雄兽连续交配时，交配间隔、交配持续时间、每次爬跨持续时间、总爬跨持续时间、最后一次爬跨持续时间、射精持续时间等行为参数以及交配栓的重量均保持不变。表明雄兽具有恒定的交配投资模式，这种模式可能起因于该物种雄性之间激烈的精子竞争。

When mating virgin females, males decreased investment in the form of copulatory plug, but increased investment in the form of behaviors, such as increased mating duration, shorten mating interval, longer duration for mountings and intromissions.

雄性与处女兽交配所形成的交配栓明显减小，却增加了行为上的交配投资，表现为与处女兽交配时交配持续时间较长、交配间隔较短、总爬跨持续时间和总插入持续时间较长。

Cotton bollwormis a polyandrous insect, and it can carry out the seconcd mating after 1d post-first-mating, and the loss substance in MAG can be compoletely supplemented with24-36hrs after mating.

棉铃虫虫是一种多次交配的昆虫，雄蛾交配后一天即可进行二次交配，交配后的棉铃虫雄蛾MAG腔内损失的物质只需24-36小时即可补充完毕。

C. albicans bar1 a cells were shown to secrete both a and mating pheromones;-pheromone activated self-mating in these cells in a process dependent on Ste2, the receptor for -pheromone.

现在，另外一种新颖的有性生殖模式已在"白念珠菌"中被发现：在特定情况下，即在没有为一种分泌出的蛋白酶编码的BAR1基因存在的情况下，高效同性交配可在a-型细胞之间进行。

Limited by the population and generations, the local search ability is not good. A new niche—Braham model is brought forward. In the Braham niche, the random mating mode between chromosomes is replaced by the mating mode based on the fitness of the chromosomes.

本文提出了一种新的小生境算子—婆罗门，将简单遗传算法中的随机交配改为根据染色体的适应度进行交配，提高了遗传算法局部搜索能力，有效地防止了基因漂移。

The effects of mating experience and temperature on the production of the female black cutworm moth's sex pheromone were studied in this paper. The results indicated that the mating experience did not significantly affect the production of sex pheromone.

中文摘要：研究了交配和温度对小地老虎雌蛾性信息素产生的影响，结果表明，交配对性信息素各组分的滴度无显著影响，因此不影响小地老虎在下一暗期的再次求偶和交配。

The average thrusting duration was 20.9±0.5 seconds,and the average mating duration was 45.2±1.3 seconds.4 There was no copulatory lock during mating,and the male usually ejaculated following a single intromission after several thrusts.

平均抽动持续时间为20.9±0.5s，平均交配持续时间为45.2±1.3s.4东北虎在交配过程中无锁结现象，雄虎通常在一次爬跨多次抽动后即出现射精。

According to rigid motion theory and composition law of vectors, the relative position and orientation errors of mating surfaces of mating parts were computed.

基於刚体运动学原理，研究了装配工夹具的姿态偏差对零件配合面位置偏差的影响，推导了配合件和基础件相应配合面的位置和姿态偏差的计算公式，建立了机器人装配系统零件配合过程的误差分析模型。

It is generally considered a selfing species with a strong self-compatibility system, but a shift in mating system towards outcrossing or mix-mating has been reported.

通常认为它是自交种，但也有些研究报道它具有异交或者混合交配的繁育系统。
