年龄

It is now known that psychological age correlates more closely to biological age than chronological age.

大家都知道心理年龄对生理年龄的影响要比实际年龄大。

And, as adolescents get older, the gap between their chronological age and their self-perceived age widens.

同时，当这些青少年年龄增长后，他们生理上增长的年龄与他们自我感觉年龄间的差距会越来越大。

There's biological age and chronological age.

年龄分为生理年龄和实足年龄。

There were 36 males and 40 females,with the average age of 47.7 years.36 patients presented with sciatica and perineal numbness,11 patients had painless mass and the other 20 were identified due to other causes.Among 67 benign neurogenic tumors,54 were originated from S1-S3 nerves,3 from S4-S5 nerves and 11 from the presacral space without caudal involvement.Giant cell tumor was found in 60 patients,which included 24 males and 36 females,with an average age of 32 years.Upper sacrum（S1-S2） was involved firstly.There were 56 patients（average,37.7 years） diagnosed as other primary benign bone tumors,which included 24 cases of teratomas,epidermoid cyst or dermoid cyst.Other malignant tumors,including chondrosarcoma （17）,Ewing′s sarcoma/PNET（14）,multiple myeloma（12）,lymphoma（6） and osteosarcoma（6） were found in 64 patients.

其中脊索瘤95例，男62例，女33例，平均年龄55.7岁，骶尾区疼痛是主要症状（82例），半数以上患者伴有坐骨神经痛，肿瘤多先累及低位骶骨（S3~S5）；神经源性肿瘤76例，男36例，女40例，平均年龄47.7岁，神经纤维瘤43例，神经鞘瘤24例，恶性神经鞘瘤9例，主诉多为坐骨神经痛、会阴部麻木（36例）和无痛性包块（11例），20例患者为查体或其他原因检查时发现，67例骶骨良性神经源性肿瘤起源于S3以上神经者54例，起源于S3以下神经者3例，发生于骶前未累及骶管者10例；骨巨细胞瘤60例，男24例，女36例，平均年龄32岁，腰骶尾部不适（37例）、坐骨神经痛（21例）是主要的临床表现，肿瘤多先累及上位骶骨（S1~S2）；骶骨其他原发良性肿瘤及瘤样病变56例，包括畸胎瘤、皮样囊肿、表皮样囊肿共24例；其他原发恶性肿瘤64例，包括软骨肉瘤17例，尤文肉瘤14例，多发性骨髓瘤12例，成骨肉瘤6例等。

China high level athletics during many years training process, there are some duffer's proportion in fitness and technique training difficult period.

3中国高水平短跨、跳跃项目运动员经过长期的系统训练，开始训练年龄、达到最好成绩年龄、结束训练年龄与运动训练学理论相一致的规律性特点。

The results show that both the incidence and prevalence rates are increasing over 1996 to 2003; the incidence rate, prevalence rate, survival function, mean onset age, and mean remaining life after onset of females are all larger than those of males. In addition, females are less biologically aged than males at the same chronological age by 1.3279 years in terms of the empirical distribution function of onset age.

研究结果显示，首发率和盛行率皆有逐年上升的趋势，而女性患者之首发率、盛行率、存活机率、首发后之平均余命皆高於男性；此外，若单纯以男、女性患者之首发年龄而论，其经验机率密度函数显示：男性患者之生理年龄比同年龄的女性患者早衰1.3279岁。

Recognized the regional geological history and the lack of external Sr sink epidote among the hydrothermal mineral assemblages, we refered that the Rb-Sr isoehron isotope date was the hydrothermal ore formation age.

因此本文通过Rb-Sr等时线所确定的250±20Ma同位素年龄具有地质意义，结合对区域地质演化史的基本认识及金矿石热液蚀变组合的研究(易捕获外来锶的绿帘石不发育)，该同位素年龄代表热液成矿年龄。

40Ar-39Ar method is the first one of the possible geochronology techniques to solve this difficult scientific problem.

油气成藏作用伴生的矿物种类少，主要为碳酸盐矿物，以及少量石英和黄铁矿等，这些矿物均不适合用传统同位素年代学方法进行年龄测定，因此，油气成藏年龄是同位素年代学尚未解决的一大科学难题。40Ar-39Ar法是可能应用于油气成藏年龄测定的首选同位素定年方法。
