He began making films in 1938 by accident , when a film producer client of the law firm he was working for fled fascist - era italy and asked him to take over 他在1938年因为一个偶然而开始制作电影，当时一个什么叉叉的电影制片的客户逃离了法西斯治下的意大利，因而不得以而请庞帝出来救场。
They act as an intermediary transducer , much as a tuning fork which when struck , and then being brought into proximity of another tuning fork , will start the second fork to begin vibrating also 他们担当了中间媒介变换器角色，非常像受了敲击的音叉，紧接着就引起了另一个音叉的共鸣，就会引起第二个音叉也同样开始振动。
This important conclusion will help to choose appropriate resonant frequencies for drive and detection modes when designing a gyro . 2 . influences of the mechanical coupling on the parameters of this gyro are presented 2 .利用音叉的振动方程,对微陀螺进行建模和分析,总结了机械耦合和微陀螺各参数之间的相互关系。
At present , it has about 350 employees , including 86 high - grade and medium - grade engineers and economy managers . the company is engaged in manufacturing various gas engine vaive seats , valve rockers and assembly , valve guides and gear - box shift forks 公司是生产各型内燃机气门座气门导管气门摇臂摇臂轴总成变速箱拔叉的专业企业。
Some researchers in universities are investigating the possibility that high levels of fat and fructose are mucking up our brain chemistry , and thereby muting the signals that would normally tell us to put down the fork 一些大学学者在研究是否过量的脂肪和果糖会扰乱我们大脑中的化学物质，从而防碍大脑在正常情况下发出让我们放下餐叉的信号。
This paper analyzes the state of hopf bifurcation in a chaotic system , judge the direction of the bifurcation by calculating the first lyapunov coefficient , and then briefly discuss some corresponding dynamic system behaviors 摘要讨论了一个混沌系统的霍普夫分叉情况，并通过计算系统的第一李雅普诺夫系数判断了其分叉的方向，对相应的动力系统行为也作了简要的分析。
We also select the region of the operating parameter that make the system in excellent station and determine the conditions for the existence of hopf bifurcation . in additional the figures of oscillations and phases are all drawed 通过计算，选取了系统处于较优状态的操作参数的范围，并判定出系统存在hopf分叉的条件，绘制了两个反应器串联时的振荡图形及其相图。
In this paper , we introduce continuous delay into the model and discuss the conditions that decide the existence of hopf bifurcation , hi addition we obtain the figures of oscillations and the phases and describe transition qualitatively 在此基础上，本文引入了连续时滞，给出了系统存在hopf分叉的条件，得出系统的振荡图像及其相图，并对过渡态进行了定性的描述。
The ttc is calculated using a method based on continuation power flow ( cpf ) , and the method is the most availability and reliability of coping with saddle - node bifurcation point in the curve result , which is validated with simulation on some calculation examples 经过算例的分析，连续潮流的计算方法在求解考虑鞍型分叉的电压稳定性约束下的输电能力最为可靠，该方法有效且实用。
