中文拼音 [héxiǎotǐxuǎnwèi]
核小體選位
英文
nucleosome positioning-
This modification includes : ( 1 ) selecting two important molecules as candidates, ( 2 ) choosing a promiscuous t - cell epitope, and two b - cell epitopes or conserved amino acid sequences from the two important molecules, ( 3 ) connecting them adequately through analysis by the molecule designing software. therefore, the synthetic new antigen may interfere with the process of fertilization by multiple ways and its contraceptive effects may be enhancing. based on the molecule designing methods, the b - lymphocyte cell epitope of sperm / testis specific protein sp17 and cyritestin which interfere with fertilization in mouse, as well as the promiscuous th cell epitope of the ribonuclease ( rnase ) in bovine were selected
本研究以蛋白質分子設計的理論和方法研究避孕疫苗，將sp17和cyritestin關鍵表位和牛核糖核酸酶非選擇性th細胞表位合理組合，獲得新抗原- 35肽序列；並在合成、純化後分別與弗氏佐劑、免疫刺激復合物（ iscoms ）混合后免疫不同遺傳背景的雌性小鼠，觀察血清和生殖道內的特異性抗體滴度的動態變化、生育力的改變以及免疫后小鼠重要臟器的組織病理學改變：以及在ivf下，新抗原的特異性抗血清對精卵相互作用的影響及抗原在精子表面的特異性定位。By increasing the h2 dilution ratio, it is found that atomic hydrogen can selectively etch amorphous phase and stabilize crystalline phase. from the study on the distance from substrate to catalyzer, choosing a proper distance can ensure the gas fully decomposed, while a relatively low substrate temperature can cause the nanocrystalline particles to lose mobility and keep their sizes. the pre - carbonization process can enhance the nucleation density and make the growth of high quality nanocrystalline p - sic films much easier
實驗結果表明：隨著工作氣壓的減小，薄膜的晶粒尺寸有所減小；通過提高氫氣稀釋度，利用原子氫在成膜過程中起的刻蝕作用，可以穩定結晶相併去除雜相；選擇適當的熱絲距離能保證反應氣體充分分解，又使襯底具有較高的過冷度，是形成納米薄膜的重要條件；採用分步碳化法可以提高形核密度，有利於獲得高質量的納米- sic薄膜；襯底施加負偏壓可以明顯提高襯底表面的基團的活性，因負偏壓產生的離子轟擊還能造成高的表面缺陷密度，形成更多的形核位置。Concretely speaking, the social factors mainly include economical treatment, social status, occupational prestige, professional organization, professional autonomy, etc. the educational factors mainly include pre - service education, appointment education, in - service training, practical training, etc. the system factors mainly include qualification system, appointment system, evaluation system, promotion system, etc. the individual factors mainly include the principal ' s self - development demand and consciousness, professional attitude and motive, career satisfaction and reflecting experience, etc. based on the investigation on the factors influencing principal professional development, this research concludes that : the society, education, system and individuality have a great influence upon principal professional development
具體來說，社會因素主要包括經濟待遇、社會地位、職業聲望、專業組織、專業自主權等；教育因素主要包括職前教育、入職教育、在職培訓、實踐訓練等；制度因素主要包括資格證書制度、選拔任用制度、考核評價制度、職級晉升制度等；個人因素主要包括校長的自我發展需要和意識、專業態度和動機、職業滿意度、反思經驗等。本研究通過對中小學校長專業發展影響因素的實證調查，得出結論：社會、教育、制度、個人四大因素對校長的專業發展均有較大影響，其中個人因素對校長專業發展的影響程度最大，其他三個因素的影響作用不存在顯著差異。
