The concept of " timing " in the article is not the clock in our ordinary living, but syntheses which is made up of some frequency source in the signal generator ( such as cs atom frequency standard, rb clock & high accuracy quartz crystal oscillator ) which produces the primary frequency, the matching input interface and the matching output interface and controlling circuit etc. for example, bits is a kind of timing equipment, which is used to control the timing of some functions
本文論及的「時鐘」概念不是指日常生活中使用的鐘表，而是由產生基準頻率的信號發生器（如銫原子頻率標準、銣鐘及高精度石英晶體振蕩器等）中的某種頻率源以及相配套的輸入、輸出介面和控制電路等組成的一整套具有特定同步定時功能的綜合體。如bits就是一種時鐘設備，它提供用在通信系統中控制某些功能的定時的時間基準設備，時鐘提供的信號稱為基準信號、定時信號或同步信號。 -
That the alloying element mn and ti substitutes the atom of fe in the rich iron - phase ( al, si, fe ) and resumes the part of the element si in primary phase refines the second phase. at the same time, the volume percentage of second phase is increased. at the course of solidification, the alternating current field changes obviously the microstructure morphology of the al - 20si - 5fe - x alloy and the number of particle eutectic structure is increased
合金元素mn 、 ti通過占據富鐵相（ al ， si ， fe ）中鐵原子的晶格位置，同時消耗部分初生相中的si元素，形成四元富鐵相（ al ， si ， fe ， mn ） ，細化了合金中的第二相，同時提高第二相體積百分數。 -
