But in the forepassed research , the people all abstracted the colloid in the water as the sphericity and explained it by the known theory of the colloid chemistry . moreover some people modified the result by the grain coefficient in the derivation of theory . but this assume had more difference on the observed phenomena in the experiment , so it was not perfect in theoretical speaking 關于絮凝的理論基礎在國外研究得比較多,但在過去的研究中,人們大都是將水中的膠體顆粒抽象為球形,用已有的膠體化學理論去加以解釋,并在理論推導中引入顆粒系數加以修正,這與實際實驗所觀察到的現象有較大的差別,從理論上說,是很不完善的。

The mechanism of anti - wear and friction reduction of nanometer cacoa has been discussed and individual opinions of the nanometer particles “ existing way and effects have been proposed . 1 ) the shape of the nanometer cacos particle is approximate to that of sphericity . its function is similar to that of the miniature “ ball bearing “ 6 、探討了納米碳酸鈣粒子的抗磨減摩機理,對于納米粒子在潤滑油中的存在方式和作用提出了個人見解: ( 1 )納米碳酸鈣粒子近似為球形,它們起了類似微型“球軸承”的作用,從而提高了摩擦副表面的潤滑性能。

After a careful comparison we found : ( 1 ) rotating the coordinate system around the z - axis for each event is necessary for the relaxation of the correlation between thrust ( or sphericity ) major - minor frame and the direction of the first hard gluon emission . ( 2 ) the horizontal factorial moments ( hfm ) are equivalent to the vertical ones ( vfm ) only after cumulant - variable transformation . therefore , in the study of nonlinear phenomena in high energy collisions the hfm can be used only in combination with the cumulant variables 工jlnfy4ww ; 6標系與發射第一個硬膠子之間的關聯效應,從而觀察到全部強度的動力學起伏;證明了:只有在引入累積變量以后,橫向矩才等于縱向矩,從而也才等效于幾率矩,困而只有在這時,橫向矩才能被使用;論證了:對eb對撞末態粒子系統動力學起伏的研究只能在全相空間進行,而不能用限定的相空間,因而只能采用丟掉最初的一個或幾個點的方法消除動量守恒對相空間標度特性的影響。

Elaborate the theoretics of making polymer grin micro - lens by means of suspension - diffusion - copolymerization and the measurement of the common optics parameter of the medium lens , such as light passing index , no - sphericity and so on , then analyze those results and make advises on how to improve 第三章介紹了懸浮擴散共聚法制備grin微球透鏡的工藝過程,及對所制備的聚合物球透鏡的折射率分布、透過率、不圓度等光學參數進行的測量。對實驗結果進行了分析,并對制備過程中工藝條件的改善提出了改進的建議。

As the eutectic time increases , the graphite morphology departs from sphericity to the abnormal morphology , and the roundness of the graphite particles decreases as well 隨著共晶時間的延長,鑄件的石墨形態逐漸偏離球形,向異常化趨勢發展,石墨顆粒的圓整度隨之降低。

Under these conditions , the prepared matrix had regular sphericity and a similar size distribution to that of the commercial streamline matrix 在此工藝條件下,復合基質具有規則的球形外觀和與商業streamline系列基質相當的粒徑分布。
