核晶時期 的英文怎麼說
中文拼音 [héjīngshíqī]
核晶時期
英文
labile stage-
For electrodeposition by dc methods, the metals deposite uninterrupted and the particles were also embeded uninterrupted into the coatings ; for electrodeposition by pc method, the particles with biggish volume were desorbed from the coatings and returned to the electrolyte again owing to the presence of pulse interval ; for electrodeposition by prc method, the particles carried positive charges are much more easy to desorb from the coatings owing to the effecf of reverse pulse current combined with pulse interval, in addition, the reverse pulse current also could dissovle the metals, further accelerates the desorption of particles, thus the particles size embeded in the coatings by prc method is the least
直流電沉積時，基質金屬的沉積連續進行，粒子在電極表面不間斷嵌入鍍層;單脈沖電沉積由於脈沖間歇的存在使得具有較大體積的粒子會脫附，重新回到溶液中;採用周期換向脈沖時，反向脈沖電流使表面荷正電的較大的粒子更易從電極表面脫附，同時，反向脈沖電流對基質金屬的溶解作用，也會促進粒子的脫附，因此鍍層中復合粒子尺寸最小。隨著鍍層中粒子復合量的增加，三種鍍層的晶粒都明顯細化，說明al _ 2o _ 3的存在阻止了晶粒的長大，提高了電沉積過程中晶核的形成速率。The reason that these hurricanes were so powerful was the sticky radioactive energy left over from two nuclear bombs detonated within the grids of this land at the end of the era of atlantis
颶風為何如此強烈的原因是，在亞特蘭蒂斯時代末期， 2次巨大的核彈爆炸后在此片陸地的晶格層中遺留了大量粘稠的放射性能量。With plating time going on, the nano - polycrystal gathering grows in two dimensions, and the new nano - polycrystal layer appears simultaneously on the formerly formed nano - polycrystal surface. because the boundary and defect densities in quenched and tempered 45 steel is higher than those in annealed steel, the nano - polycrystal gatherings formed at its surface at the beginning of electro - deposition are more concentrated, and then their size is smaller. the microstructure of the ni - p alloy coating has closed relation with its phosphorus content with the increase of phosphorus content, the microstructure of coating turns from nano - crystalline to the amorphous
隨著施鍍時間的延長，納米晶聚晶體在橫向二維生長的同時，在納米晶聚晶體的表面上也進行著三維方向的新的一層聚晶體的生長；在調質態45鋼表面，由於其具有比較高的晶界和缺陷密度，因此在沉積初期，納米晶聚晶體的成核密度也較大，從而在二維方向聚晶體的尺度較小，鍍層沉積初期表現為緻密細小的鱗片狀組織。The main works were listed below : 1. as the core of image tracker, the advanced dsp technology ( adsp - ts201 ) and the programmable logic device ( ep1s40f1020 chip ) were combined together to make certain that instruction was completed within single instruction period
主要體現在下面幾點: 1 .圖像跟蹤器的硬體平臺以先進的dsp技術（ adsp - ts201 ）和可編程邏輯器件（ stratix系列的ep1s40f1020晶元）為核心，構成實時的圖像跟蹤處理器，使得指令可在單指令周期內完成運算。The sample thickness declining, provided the number of nuclei per unit volume fix, the value of the avrami exponent n falls, but the values of vc and s almost do n ' t change. when the value of thickness reduce to the average diameter of entities, the turning point turn up after the course of crystallization has begun soon
當單位體積內晶核數目不變時，樣品厚度h減小， n減小； v _ c和_ s值基本不變：當h降到小於等於體系內球晶的平均直徑時，在結晶最初期，會出現一個初期轉折點。分享友人
