gephyrocapsa
解釋
橋顆石-
This result was the biochronological base for estimating sample ages in the study on genus gephyrocapsa. 2. morphological variation of gephyrocapsa was investigated based on biometrically analyzing 6 morphological features of a coccolith placolith, e. g
（ 2 ）結合時間序列來對橋石種類的在演化的過程中形態變化進行分析，發現在整體演變的進程中，幾種形態因子中一直處在最劇烈變化中的是盾盤的長度。 -
This study is a post - cruise study of this leg, calcareous nannofossil samples from sites 1146, 1147 and 1148 of leg 184 were analyzed to provide a high - resolution biostratigraphy for this leg and to investigate morphological variation of coccolith genus gephyrocapsa. the main results of this study are : 1. 12 late pliocene to pleistocene bio - events were recognized and 6 zones of martini ( 1971 ) were determined for the upper sediment sequences of sites 1146 and 1148
本文作為大洋鉆探項目船下后續研究的一部分，對184航次中的1146站位和1147 、 1148站位的樣品進行了分析和研究，在船上科學家已經建立起的地層框架的基礎上進一步加密采樣，對生物事件標志化石類別進行數量統計，進一步確定了12個生物事件在鉆孔中的深度，建立起了兩個站位的高解析度的鈣質超微化石生物地層框架。 -
The results suggest that a number of species of gephyrocapsa can be separated by using three pairs of following morphological features : 1 ) placolith length against bridge angle, 2 ) bridge angle against roundness, 3 ) placolith length against placolith width. in pleistocene, at about 1. 3 ma, a notable variation in placolith length and bridge angle occurred, while the genus boosted according to the result of earlier studies on this genus ( su, 1996 )
通過對幾種形態因子進行相關分析，發現橋的角度變化與盾盤大小的變化呈現極顯著負相關，即當盾盤長度比起老地層中的種類有所變大的時候，橋角有變小的趨勢；而當盾盤長度比起老地層中的種類有所變小的時候，橋角有變大的趨勢。 -
This study also observed, in the morphological development of gephyrocapsa, there is a significant negative correlation between placolith length and bridge angle, between placolith length and roundness, as well as between placolith length and pore size
這一結論，與su （ 1996 ）在北大西洋所作的橋石屬形態研究是相吻合的。有關形態變化的機制或環境因素影響尚待研究。
