Based on the analysis of thermal contact metamorphic aureoles, granitoid interior structure, quartz axis fabric and strain characters in the different rock unites of yuanshishan granitoid and its wall rocks, the emplacement mechanism of yanshishan granitoid was studied. the magmatic explictite dynamic was advanced in light of regional stress and magma dynamic research. those conclusion was synthesized to ascertain the emplacement mechanism - granitic magma ascended in dikes with the minimum critical width of the magma ascending channels about 2. 213. 88m and located in the core of yindianshan dome with the passive style of dyke explictite ; the later unite is a kind of multiple emplacement mechanism with the character of active emplacement of ballooning
同時運用巖漿動力學原理從另一個角度探討其侵位驅動力。綜上指出：經分凝后的活動性巖漿在深部側向擠壓和浮力的聯合驅動下，沿深大斷裂以最小臨界寬度為2 . 213 . 88m的裂隙脈動上侵，整體以巖墻擴展的方式被動定位於銀殿山穹窿的核部，但後期屋面前單元具有主動侵位的特點應為一種復合定位機制。At the onset of mitosis, prophase, the nucleolus breaks down.
有絲分裂的開始稱為前期，核仁消失。After the treatment was removed for 6 min, the nucleus began to reform in those eggs that the spindle did not recover. after 9 min, new nuclei had been reformed completely. the activated eggs entered the prophase of the next cleavage cycle in about 14 min, the metaphase in 19min ; the anaphase in 24min and the telophase in 29min
未恢復紡錘體的激活卵在解除休克后6min ，卵內染色體開始核化， 9min時形成新的二倍體細胞核， 14min時處入再次分裂的前期， 19min時進入分裂中期， 24min進入分裂後期， 29min時處于分裂末期，且可以看到子核的形成。In this paper, the effect of nuclear actin on the process of chromosome construction has been studied by utilizing the precise natural synchrous plasmodium of physarum polycephalum, sds - polyacryl amide gel electrophoresis ( sds - page ), western blotting, the cell - free system and optics microscopy. the major results and conclusions are as follows : 1
本實驗以多頭絨泡菌原質團為材料，採用同步化培養、細胞核提取、 sds - page 、免疫印跡、非細胞體系構建、光學顯微鏡觀察等方法，研究了有絲分裂前期核內肌動蛋白對染色體構建的影響。There are three difficulties and key problems in this papaer : : the first problem is what is the dominance bearing of the leakage fractures, and how the bedrock fracture water distribute, the second is how to test the complex chemical behavior in experiment way and quantify the relative parameters, the last question is how to number the transportation of the element 90sr and its pollution to solve the three problems, this paper does lots of work and come to the prospective order, the creativities in this thesis as follow : ( 1 ) the dominance bearing of the leakage fractures and the distribution feature of the fracture water are ascertained based on rich geological data, these basal researches are very important, which are the premises to build the transport model of the fracture water in hae field
本項研究工作的難點和關鍵問題有三個： hae處置場基巖裂隙系統中，導水裂隙的優勢方位是什麼，基巖裂隙水活躍帶分佈情況如何；怎麼對核素遷移的復雜化學行為進行實驗室測試並取得有關定量化參數；怎樣數值化表現出溶質的遷移行為和污染情況本論文在解決以上三個問題上做了大量的工作，達到了預期的目的，其創新之處有以下三點： （ 1 ）通過地質資料的分析，首次提出了hae預選處置場基巖裂隙導水的優勢方位和基巖裂隙水活躍帶的大致分佈特徵。它是一個很重要的基礎性研究成果，是建立hae處置場水運動模型的前提。In the course of present investigation in interspecific hybrid of tritical crops, cytomixis mas observed at microspore stage, the present investigation deals with detailed analysis of this phenomenon at different conditions
作者在麥類遠緣雜種的減數分裂過程中發現，在減數分裂的前期和小孢子時期均存在核穿壁的現象，並對各種狀態下的穿壁現象進行了詳細的觀察研究。L were studied. during the meiotic process of megasporocyte, the ribosome population diminished greatly in prophase i and restored in metaphase i ; plastids and mitochondria turned unclear dedifferentiation in prophase i and recovered their normal structures redifferentiation in metaphase i. all these proved that cytoplasmic reorganization took place during the megasporogenesis of
發現了小麥大孢子母細胞減數分裂過程中，核糖體密度在前期顯著降低，到中期才完全恢復質體和線粒體也出現了脫分化和再分化。從而證明了小麥的大孢子形成過程中也存在著細胞質改組現象。Cultured epithelial cell undergoing division. this cell is in prophase of mitosis. microtubules are shown in green, actin is in red and mitotic chromosomes are colored blue
以上兩圖為正處于有絲分裂前期的動物上皮細胞。綠色的是微絲，紅色為肌動蛋白，染色質高度螺旋成為粗短的染色體（藍色） ，核膜核仁逐漸解體，染色體不規則地分佈於細胞內。After the nuclei of late g2 phase were incubated in the mitotic extracts harvested from metaphase plasmodia, the cyclin b in the nuclei gradually accumulated with the prolongation of incubating time. while, in the control group, the content of cyclin b changed little. this indicated that the mitotic extracts of metaphase plasmodia had the activity of accelerating the process of prophase, and the cell free system with mpf activity was established
將g _ 2晚期細胞核溫育于中期提取物中，免疫印跡結果表明隨著溫育時間的延長，細胞核中cyclinb的含量逐漸增加，而在沒有中期提取物的對照組細胞核中cyclinb含量並不隨著溫育時間的延長而增加，說明多頭絨泡菌中期提取物具有促進有絲分裂前期進程的作用，同時也說明我們構建了具有mpf活性的非細胞體系。As cyclin b is the mark protein representing the process of prophase, we infered that cytochalasin b destroyed the polymerization of the nuclear actin and directly affected the process of prophase. nuclear actin played an important role in the process of the chromosome construction
因為cyclinb是有絲分裂前期進程的標志性蛋白，所以我們認為細胞鬆弛素b破壞細胞核內肌動蛋白聚合后，直接影響了有絲分裂前期的進程，進而悅明核內肌動蛋白在有絲分裂前期染色體構建過程中起著重要作用。Cyclin b can be a kind of mark protein which represents the process of prophase
細胞核中cyclinb的含量變化可以作為有絲分裂前期進程的標志。分享友人
