I am a boy who is doing my post - graduate work in nanking . i like music , reading books , and politics . i ' m my own most severe critic and i have fecundity of the mind . i am happy to make friend with both boys or girls . i would like to talk with some foreigners who speaks english 我是一位在南京在讀的碩士研究生,主要從事光通信方向的研究.我是一個對自己要求嚴格的人.有時候也會讓人覺得太認真.所謂“酒逢知己千杯少,話不投機半句多. “所以我希望能夠認識一位值得交往的人品好的好朋友或者紅顏知己

Gonadal development and fecundity are affected by certain essential dietary nutrients , especially essential amino acids , essential fatty acids , and vitamins etc . thus , during the last two decades , more attention has been paid to the optimal level of different nutrients in broodstock diets . it is well known that protein is a kind of indispensable nutrient because of its important physiological function on body structure and supplying energy to the growth and development of shrimp and crab . protein and amino acids of broodstock diet have been identified as major dietary factors that determine successful reproduction and survival of offspring 而這些問題的解決則要求對中華絨螯蟹生殖過程中的攝食和消化生理機制,親體性成熟期對各種必需營養素(如必需氨基酸、必需脂肪酸和維生素等)的需求,卵細胞發生過程中營養物質的合成、轉運及貯存規律,以及在受精卵、胚胎和后續以內源性營養為主的?狀幼體發育階段對卵黃磷蛋白的消耗和利用模式等環節進行較為深入的研究,在全面系統地了解中華絨螯蟹的生殖營養生理的基礎上,探討親體生殖營養對卵質、孵化及后續幼體生長發育的影響。

These bacteria are transmitted through the cytoplasm of eggs and have evolved various mechanisms for manipulating reproduction of their hosts , including cytoplasimic incompatibility ( ci ) , parthenogenesis , feminization , male killing , fecundity or fertility modifying etc . wolbachia are common and widespread bacteria infecting 17 % insect population , 17 crustacean species , mites and many nematodes 這些共生菌通過母系遺傳參與調控寄主的多種生殖活動,包括細胞質不親和現象、誘導孤雌生殖現象、雌性化、雄性致死以及調節寄主生殖力等。 wolbachia的分布十分廣泛,目前已經發現在超過17的昆蟲種群以及17種甲殼綱動物、螨蟲、線蟲體內發現了它的存在。

The mean absolute fecundity was 4337 . 81 2541 . 26 , and the mean relative fecundity was 27 . 09 11 . 09 . the absolute fecundity increased with the increase of body length , body weight , somatic body weight and gonad weight , while there was no significant relationship between relative fecundity and body length , body weight or somatic weight 平均絕對繁殖力為4337 . 81 2541 . 26粒,平均相對繁殖力為27 . 09 11 . 09粒g ,絕對繁殖力隨體長、體重、空殼重、性腺重的增加而增加,而相對繁殖力隨體長、體重、空殼重的變化不明顯。

It has been confirmed that np30 has sensitizing effect on formation of hepatic egg granulomas in mouse model for hepatic egg granuloma of schistosoma japonicum ; immunization with np30 in kunming mice , c57bl / 6 mice and goats obtained worm reduction of 50 . 46 % , 41 . 67 % and 42 . 78 % , respectively . np30 possesses effects of both anti - fecundity and anti - embryonation immunity on female worms of s . japonicum . moreover , np30 plays a significant down - modulatory role to hepatic granuloma and fibrosis ( the diameter , area and volume of egg granuloma were all significantly less than those of control ; the contents of type i , iii of collagen and fibronectin were also significantly less than those of control ) 已對np30分子進行了較為廣泛的研究,應用小鼠日本血吸蟲肝肉芽腫模型證實np30對蟲卵肉芽腫的形成具有致敏作用;對感染宿主(昆明種小鼠、 c57bl / 6小鼠和山羊)具有較好的免疫保護作用(減蟲率分別為50 . 46 、 41 . 67和42 . 78 ) ;用np30主動免疫小鼠具有抗雌蟲生殖產卵和抗卵胚發育的雙重功效;另外,還對血吸蟲病肉芽腫和肝纖維化有明顯的負調節作用(蟲卵肉芽腫的直徑、面積和體積均明顯小于對照組,肝組織、型膠原及纖維連接蛋白含量均低于對照組) 。

The seasonal and diel variation in fecundity of females in situ . were observed , and the pattern of spawning and its ecological significance were also discussed . the differences of biochemistry component , respiration , isoenzyme , and total proteins electrophoresis between diapause and subitaneous eggs were preliminarily investigated as well 本文通過對海區雌體現場產卵情況季節性和晝夜性變化的觀察結合海區環境的季節變化,探討其產卵變化的規律和生態意義;還初步研究了剛產出的滯育卵與正常卵的生化成分差異、呼吸代謝特征、同工酶差異和全蛋白電泳差異。

The reasons of small resource are 1st , the fish eggs is lack of sticky and most spawning ground is not comfortable for spawning ; 2nd , the fish matures about 5 years old and fecundity is in low level on absolute or relative eggs amount ; 3rd , the shape is easier for catching with tall width and thin body 黑龍江魴資源量少的原因為:黑龍江魴為產弱黏性卵的魚類,對產卵場的要求較高。黑龍江魴的性成熟年齡較大( 5齡) ,而且無論是絕對懷卵量還是相對懷卵量都較低,因此生殖力較低。黑龍江魴由于體形高而側扁,極易被捕撈。

The authors further note that the new wings did not re - evolve from scratch ; genetic blueprints seem to have lain in wait for at least 50 million years , until flight was favored over fecundity ( wingless insects tend to lay more eggs ) 他們進一步指出,新的翅膀并非重頭開始再演化的結果,相關的遺傳藍圖似乎已蟄伏了5000萬年以上,直到飛行在繁殖上取得優勢后才重出江湖(無翅昆蟲通常比較多產) 。

At the same time , the age structure , time - specific life table , survivorship curve , fecundity schedule and leslie matrix were obtained through ana1ysing the demography and age struct ' ures of each subpopulation 對種群年齡結構研究中,編制了種群靜態生命表、生殖力表,利用建立的矩陣模型預測了種群數量的動態趨勢,并進行了環境篩的分析,推斷了種群致危因素。
