Further, on the basis of removing the factors which affect seismic velocity, such as earth′s surface, seismic processing technique and particular lithesome, the comprehensive researches indicate that the east prominent is intimately adjacent to the gas generating sag, and the reservoir bed and capping bed arrangement condition is very good. The east prominent has the feature of late gas accumulation and has the petroleum geology conditions of forming large scale natural gas pool.

进而，在排除影响地震速度的地表、处理流程、地下特殊岩性体等主要因素的基础上，通过石油地质综合研究认为，构造东高点紧邻生气凹陷、深层储、盖配置良好、晚期成藏，具备形成大型天然气藏的地质条件。

They also noted that a radiograph of the hand is useful for determiningwhether the digital phalangeal epiphyses are capped (post-peak height elocity) or uncapped (pre-peak height elocity) because capping strongly correlates with the timing of peak height elocity, an important parameter to study when predicting cure progression.Dimeglio et al.

还发现手部平片在确认手指近端骨骺扩张或未扩张方面有用处，因为骨骺扩张与峰值出现时间相关性很强，是预测曲线回归的重要参数。

For laser use in pulp capping and pulpotomy, an appropriate parameter must be selected. If the laser energy is too strong, the treatment will be unsuccessful.

为了能使激光应用于盖髓术和切髓术，必须选择合适的参数，因为如果激光能量太强，治疗就不会成功。

Hepatitis B virus is the smallest DNA virus which is a member of the viral family Hepadnavirida. It uses its DNA as template and the RNA polymerase II of the host cells to transcribe its viral transcripts. There are four major RNAs transcribed from HBV genome. All of the four major transcripts are unspliced, terminated at a common site, polyadenylated at the 3' terminal and capped at the 5' terminal.

B 型肝炎病毒属於肝病毒科，为目前已知最小的去氧核醣核酸病毒，利用其病毒的去氧核醣核酸以及宿主细胞内的核醣核酸聚合酶可转录出四种主要的核醣核酸产物，此四种主要的转录产物均未经剪接并终止於核心开放编阅序列的共同polyadenylation 讯号，且在其5'端均经过capping修饰。
