  1. 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。

    論文最後通過黃河小浪底水利樞紐工程中合同管理與索賠這一具體案例的分析，再一次證明了只要我國的工程建設主體按現代企業制度進行管理，真正實現與國際慣例接軌，嚴格實施項目業主負責制、建設監理制、招標承包制，按照fidic合同條件進行項目管理，採取措施保證監理工程師的地位和權利，並不斷提高監理工程師的水平，我國的工程項目管理水平將會得到更大提高，工程項目在建設周期、工程質量和投資控制等方面均會收到理想效果。
  5. The whole paper consists of three parts : part is about general theory of the least positive period, which argues the necessary and sufficient condition for the existence of the least positive period for a periodic function, and concludes " the existence of the least positive period for that periodic function, which is continuous at least one point and not equal ever to a constant " ; part researches the least positive period for the sum of two periodic functions, followed its general expression ; part discusses non - periodicity for the compound function constructed by a periodic function and a non - periodic function, and the corresponding results

    全文分為三部份：第一部份是關于最小正周期的一般理論，得到了周期函數有最小正周期的充分必要條件，也獲得了「至少在一個點連續且不恆等於常數的周期函數必有最小正周期」的結論；第二部份分析了兩個周期函數之和的最小正周期的問題，給出了其一般表達式；第三部份討論了周期函數與某些類型的非周期函數構成的復合函數的非周期性問題，並得出相應結論。
