查询词典 closed circuit

But Lovelock saw that if you had a vast network of coevolutionary impulses, such that no creatures could escape creating its own substrate and the substrate its own creatures, then the web of coevolution spread around until it closed a circuit of self-making and self-control.

洛夫洛克别认为，如果你拥有一张具有共同进化冲力的巨大的网，一张任何生物都逃避不了编织自身及其产物基质的网，那么，这张进化之网就会播撒开来直至它关闭自我制造和自我控制的回路。

But Lovelock saw that if you had a vast network of coevolutionary impulses, such that no creatures could escape creating its own substrate and the substrate its own creatures, then the web of coevolution spread around until it closed a circuit of self-making and self-control.

他认为，假使有一张具有共同进化冲力的大网，它网罗所有生物使无可逃遁地为它织造扩展所需的基质，而且这基质不断地增殖的话，这个共同进化的网络就会向周围扩展直到封闭成为一个自给自足、自我控制的轮回。

But Lovelock saw that if you had a vast network of coevolutionary impulses, such that no creatures could escape creating its own substrate and the substrate its own creatures, then the web of coevolution spread around until it closed a circuit of self-making and self-control.

但洛夫洛克别有见地，他认为，假使有一张具有共同进化冲劲的大网，它网罗所有生物使其无可逃遁，生物创造自身存活所在的基质，而基质又创造存活其中的生物，这个共同进化的网络就会向周围扩展直到封闭成为一个自给自足、自我控制的轮回。

After they are disconnect ed, the joint with the self-closed function can prevent the outward seawater ent ering, and prevent the inner hydraulic oil drainning. After they are connected, the fluid circuit is opened by the pressure of the fluid.

这种接头具有自封闭功能，在两油路分离后可以防止外部的海水进入管路，也可以防止管路内的液体流出，连接后，在流体压差的作用下，两液路接通。

Dynamic large-signal, DC, and small-signal circuit models including parasitic resistances and current ripples of nonideal synchronous rectifier buck converter operating in CCM are established. Closed-loop modeling of nonideal synchronous rectifier buck converter for voltage-mode control is studied. Transfer functions are obtained. Effects of parasitic components on control loop design of the converter are explored. Systematic simulation analysis is performed. All the results show that it is necessary to include parasitic components of converters into equivalent models.

首次建立了考虑寄生电阻和电流纹波的同步整流 Buck 变换器在连续工作模式下的大信号平均模型、DC 和小信号电路模型，研究了电压控制的闭环建模，导出了传递函数，剖析了变换器的寄生参数对其控制电路设计的影响，进行了小信号特性的仿真研究，进一步阐明了考虑变换器的寄生参数建模的必要性。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。

The cost of moving grain food products was unchanged from May, but year over year are up 8%.

粮食产品的运输费用与5月份相比没有变化，但却比去年同期高8％。
