synchronous和simultaneous的区别

同步稳步增长,英文
同步稳步增长,增长率为62%.中文有这样说的么?
股沟翻译说是：Synchronous steady growth rate of 62%
对么?

This unrehearsed,synchronous unfolding ofevents creates a village
story.Movers and witnesses participate within the complexity of their
individual personalities,doing what they each must do.It is the story of
a collection of people bringing unconscious material into consciousness,
through embodiment,because of each other.It is not unlike a cluster of
cells,like the heart,in which each cell is doing what it must do,resulting in a pumping heart.

Synchronous rectification reduces conduction losses in
the rectifier by shunting the normal Schottky catch diode
with a low-resistance MOSFET switch. Also, the synchronous
rectifier ensures proper start-up of the boost gatedriver
circuit. If the synchronous power MOSFETs are
omitted for cost or other reasons, replace them with a
small-signal MOSFET, such as a 2N7002.
If the circuit is operating in continuous-conduction
mode, the DL drive waveform is simply the complement
of the DH high-side drive waveform (with controlled
dead time to prevent cross-conduction or “shootthrough”).
In discontinuous (light-load) mode, the synchronous
switch is turned off as the inductor current
falls through zero. The synchronous rectifier works
under all operating conditions, including Idle Mode.
The SECFB signal further controls the synchronous
switch timing in order to improve multiple-output crossregulation
(see Secondary Feedback Regulation Loop
section).
