  1. In the first trial, combination of enzymatic digestion was used to prepare suspensions of spermatogenic cells from adult mouse testis, and then a modified discontinuous percoll gradient centrifugation method ( 15 %, 22 %, 30 %, 40 %, 50 %, 60 % ) was introduced to isolate spermatids from the cellular suspensions. the content of spermatids in each isolated fraction by percoll method was determined by morphology ( wright - giemsa stain ) and flow cytometry analysis, and the viability of spermatogenic cells was assessed by using eosin y exclusion test

    在第一部分試驗中，首先利用連續3次組合酶消化成年小鼠睪丸制備睪丸細胞懸液，然後經6層非連續percoll梯度離心法（ 15 、 22 、 30 、 40 、 50和60 ）分離，通過形態學和流式細胞術鑒定南京醫科大學碩士學位論文各個percoll組分中精子細胞的含量，並以伊紅y排斥試驗測定細胞的存活率。
  2. Blade design optimization problems are multimodal and discontinuous problems, the use of gradient - based numerical optimization algorithms perform inefficiently and drop into local minimum prematurely. hence, the exploratory algorithms such as gas are required for global exploration. 4

    4 .通過rsm方法擬合復雜的響應關系，平滑設計空間「噪聲」 ，能夠防止數值優化方法陷入局部極值點，獲得良好的魯棒性和適應性。
  3. In the second trial, this modified discontinuous percoll gradient centrifugation method was introduced to isolate spermatids from the semen of fifteen male infertile patients. then the effect was identified by wright - giemsa stain, flow cytometry analysis, immunocytochemistry and fluorescence in situ hybridization ( fish ). similary, the 22 % percoll fraction contained mostly haploid cells [ ( 91. 85 ? 5. 18 ) % ] ( p < 0. 005 ) and the mean density in this fraction was ( 1. 010 ? 0. 786 ) x 105 / ml

    C法，對15例各種類型不育患者的精液細胞進行分離，並利用瑞姬染色法、流式細胞術、免疫細胞化學和熒光原位雜交oisffi等方法，從細胞形態特徵、 dna倍體、細胞表面標i己與分化抗原，以及原位雜交信號的數目和位置結合細胞核特有的形態等方面加以鑒定。
  4. So a lagre populations of relatively purified spermatids can be isolated from mouse testis by enzymatic digestion combined with discontinuous percoll gradient centrifugation method

    因此採用組合酶消化結合非連續percoll梯度離。 g法，可有效地從小鼠睪丸中分離到較多較純的存活精子細胞。
  5. Furthermore, electric - thermal property can be realized and thermal stress can be reduced in cf cement - based fgm in which the discontinuous carbon fibers are gradient distribution

    碳纖維梯度分佈，使得在纖維用量最少的情況下實現了導電發熱功能，並有效地改善了內部溫差和溫度應力，緩解了應力集中。
