有絲分裂形成
英文
mitogenesis-
140min, chromosomes of the daughter cells are situated at metaphase of the second karyokinesis, while the daughter cells do n ' t separate
120min ，染色體處于有絲分裂末期，分裂溝形成，受精卵徑裂為二細胞。受精140min ，再徑裂為4細胞。During male gametogenesis, the spermatogonia became primary spermatozoa through mitosis, and then became fourth equivalent cytoplasm, round sperm through meiosis. after maturation, they participated in embryo development with the mature oocyte through fertilization. but in female gametogenesis, the primary oocyte formed a matured egg and 1 ~ 3 polar bodies ( pb )
雄性動物精子發生過程中精原細胞最後一次有絲分裂形成二倍體精母細胞后，經過兩次減數分裂形成了四個含等量細胞質、圓形的精子細胞，最終發育成四個具有正常生理功能的精子，與成熟卵母細胞受精后參與胚胎發育。Alternatively, like allopolyploids, they may arise by the nondisjunction of chromatids during the mitotic division of a zygote
與異源多倍體相似的是，它們也是在有絲分裂中合子的染色單體不分離形成的。In fetal gonad, oogonia become to primary oocytes by beginning of the first meiosis, and oocytes will be enclosed by ovarian somatic cells and further form the primordial follicles
在體內，卵原細胞會停止有絲分裂、啟動並進入減數分裂而轉變為卵母細胞，進而被周圍的體細胞包圍形成卵泡。Cell plate a structure that appears in late anaphase in dividing plant cells and is involved in formation of a new cell wall at the telophase stage of mitosis
細胞板：植物細胞分裂晚後期出現的一種結構，它和有絲分裂末期新細胞壁的形成有關。A reliability experiment of thermal aging was carried out for the two types of joints, scanning electron microscopy, energy dispersive x - ray spectrometer and micro x - ray diffractomer were adopted to investigate the interfacial evolution behavior of joints, and kinetics model of imc formation was established. the results show that imc growth follows the parabolic law as a function of aging time at certain aging temperature, imc growth is more sensitive to the aging temperature than the aging time, the activation energy of cu - al imc growth is 97. 1kj / mol and the major forming cu - al imc are cual2 and cu9al4, the activation energy of au - al imc growth is 40. 1kj / mol and the main au - al imc are au4al and au5al2, with au2al and aual at the interfacial periphery of joints, the rate of cu - al imc growth is about 1000 times slower than that of au - al imc, and kirkendall voids and cracks are easily appeared during thermal aging in gold ball bonds while voids and cracks are absent in copper ball bonds even after aging at 200 for 2900 hours and 250 for 169 hours
研究結果表明:金屬間化合物厚度與老化時間的關系符合拋物線法則，金屬間化合物的生長對老化溫度比老化時間更加敏感; cu - al金屬間化合物生長的激活能為97 . 1kj / mol ，老化后金屬間化合物呈層狀分佈，主要相為cual2和cu9al4 ; au - al金屬間化合物生長的激活能為40 . 1kj / mol ，主要相為au4al和au5al2 ，同時在界面周邊區域生成了au2al和aual ;老化過程中cu - al金屬間化合物生長速率比au - al金屬間化合物生長速率小103數量級;金絲球鍵合點200老化96小時出現了明顯的kirkendall空洞和裂紋，但銅絲球鍵合點200老化2900小時和250老化169小時都沒有形成空洞和裂紋。W7 was added when the cells entered anaphase, we found that although some cells had elongated, the distribution patternof cam at central spindle was normal, and it seemed that a cleavage furrow would possibly form soon, however, these cells stopped cytokinesis at this stage, no furrow ingression followed
在細胞進入有絲分裂後期時，加入w7 ，我們發現有的細胞雖已拉伸變長，中區紡錘體處也有gfp cam的分佈，存在形成分裂溝的跡象，但分裂溝卻不繼續縊裂加深。B - actin primers : forward 5tcc tat cgg cct cct cct ac 3 " and reverse 5aga atg tag tcc gcc agg tc 3 ", designed for 200bps. saodn oligodeoxynucleotide of pkb : stac agc ctg aga gga cct acc tg3 "
在有絲分裂期， edc25經歷216位ser磷酸化同時其水解酶活性增強，活化的mpf磷酸化並活化edc25 ，形成正反饋，結果進一步活化mpf前體，活化的mpf促進細胞周期g2 / m期轉換。The modulus and strength of pet / mmt fiber were lower than those of pure pet fiber. this is probably because the lamellar montmorillonite does not disperse randomly and completely, and besides, the spinning and drawing process in our research is limited to make the montmorillonite layers better oriented along the fiber
但pet mmt復合纖維的模量及斷裂強度比純pet纖維稍有下降，這是因為在pet mmt復合材料中蒙脫土片層還沒有達到理想的無規分散，存在一定的團聚及未完全剝離現象，此外現有的紡絲拉伸工藝還不能使蒙脫土片層在纖維縱向形成很好的取向。分享友人
