In natural seawater , the optimum k + is + 40mm tea ( tetraethylammonium chloride ) , a potassium channel blocker , cannot inhibit the s . canopus larval settlement and metamorphosis induced by k + - elevated seawater . this appears possible that potassium channels mediate the induction of settlement and metamorphosis by k + in s . canopus larvae , but that k + conductance through these channels is insensitive to external tea K +通道的阻遏劑tea ( tetraethylammoniumchloride )不能影響由高濃度k +誘導的冠瘤海鞘幼體的附著變態，因此猜測誘導冠瘤海鞘幼體附著和變態的k +通道屬于對外源tea無敏感性的那種類型。
During experiment , acetylcholine shows significant inhibitory effects on the settlement and metamorphosis of ascidian larvae , but its concentration cannot lower 1 x 10 - 7mol / l . similarly acetylcholine , y - aminobutyric ( gaba ) and picrotoxin also can inhibit the settlement and metamorphosis of s . canopus larvae 實驗中，乙酰膽堿對冠瘤海鞘的附著變態表現出抑制作用，但當濃度降低到10 ~ ( - 7 ) mol l時，此作用已不明顯。
In order to understand the mechanism of settlement and metamorphosis in styela canopus primarily , experiments observated the embryo stage of s . canopus and studied some chemical and biological factors which affect the settlement and metamorphosis of s . canopus larvae 在實驗室條件下，對冠瘤海鞘( styelacanopus )的胚胎發育階段進行了觀察，研究了影響其附著變態的一些化學和生物因子，初步解釋冠瘤海鞘幼體附著變態的機制。
In the aspect of microfilms , we isolated four bacteria which can induce the settlement of s . canopus larvae . they are h - 9 ( vibro ) , h - 6 ( vibro ) , h - 15 ( achromobacter ) h - 13 ( achromobacter ) . h - 4 ( vibro ) can inhibit the settlement of larvae 在微生物粘膜方面，本文共篩選出4株單菌菌株對冠瘤海鞘幼體的附著有促進作用，它們分別是：弧菌屬的h - 9和h - 6 ，無色桿菌屬的h - 15和h - 13 。
The induction of the mixed films of 9 bacteria is like that in field . 5 . through extracting the tunic of styela plicata and s . canopus , we found their dissolvable extracts can induce the settlement and metamorphosis of s . canopus larvae 對皺瘤海鞘( styelaplicata )和冠瘤海鞘被囊進行了初步的抽提，發現所制得的水溶性抽提物能顯著地促進冠瘤海鞘幼體的附著和變態。
1 x 10 m l - dopa can induce the settlement and metamorphosis of s . canopus larvae . but , adrenaline and noradrenaline do n ' t show any significant effects on the settlement and metamorphosis of ascidi an larvae 對于l - dopa和兒茶酚胺類神經遞質， 1 10 ~ ( - 6 ) m的l - dopa顯示出對冠瘤海鞘幼體的附著變態有誘導作用，而腎上腺素和去甲腎上腺素的誘導作用均不顯著。
So , we extracted the s . canopus larvae and found the crude extract can facilitate the settlement and metamorphosis of s . canopus larvae in some degree but the effect is not significant as that of the tunic of styela plicata and s . canopus 本實驗還從海區中生長的三種海綿和長石藥（ ual 。）中篩選出兩種海綿（粘山海綿地…刀iespp和礬海綿m 。
Increasing or decreasing calcium in artificial seawater cannot affect the settlement of s . canopus larvae , but elevating or reducing calcium concentration in artificial seawater will inhibit the metamorphosis of s . canopus larvae 人工海水中添加或減少ca2 +濃度對冠瘤海鞘幼體的附著影響不大，但無論是高濃度或是低濃度都會抑制其變態。
Larvae of s . canopus develop competence to initiate settlement and metamorphosis at least 3 hrs after hatching . but if not any induction , s . canopus larvae can retain a stage of plankton at least 3 - 4 days . 2 在孵化出后3h ，冠瘤海鞘才開始具有附著變態的能力，但在沒有任何誘導物的情況下，有的幼體能保持浮游幼體階段長達3 - 4天。
S . canopus is one of common biofouling organisms in xiamen harbor . studying the mechanism of the settlement and metamorphosis in s . canopus is the key of controlling them 冠瘤海鞘是廈門港海區常見的污損生物之一，研究其附著變態的機制對其的防除有重要意義。
The seawater containing high concentration potassium ion or containing low concentration magnesium ion can induce the settlement and metamorphosis of s . canopus larvae 在人工誘導物中，高濃度的k +和低濃度的mg2 +均能顯著提高冠瘤海鞘幼體的附著率與變態率。
Because we did n ' t study the effects of bacterial exopolymers on the settlement and metamorphosis of s . canopus larvae , we ca n ' t determine which is more important 9種細菌的混合菌膜對海鞘幼體的附著變態均表現出的誘導作用，與自然海區的情況類似。
During the experiment , we found an interesting thing : high - density larvae can facilitate the settlement and metamorphosis of s . canopus larvae 因在實驗中發現，高濃度的海鞘幼體（ ic只l ）有促進海鞘幼體附著變態的現象。
Things took an unexpected turn for the better , however , with the discovery of a natural wormhole near the system of canopus 正如一切轉機一樣令人料想不到，人們在位于船底星座的老人星附近發現了一個天然的蟲洞。
Moreover , the films mixing 9 bacteria can facilitate the settlement and metamorphosis of s . canopus larvae 此外， 9種細菌的混合菌膜可顯著地促進冠瘤海鞘幼體的附著與變態。
Larvae of s . canopus were hatched at 9 . 5 - 11 . 0 hrs post - fertilization at 25 ? . 5 ? and salinity 27 ppt 5 、鹽度為27的條件下，冠瘤海鞘從受精卵到幼體出膜約需9
