However, the Nb/Ta ratios lower than chondrite value (～17) in eclogites are inconsistent with previously proposed Nb/Ta high in subducted oceanic crust to complement the mass balance of Nb and Ta in the evolution of continental crust.

柴北缘沙柳河、鱼卡河、锡铁山和胜利口的榴辉岩类样品的地球化学分析显示它们的原岩的主体是与洋壳有关的火山岩，其中包括岛弧拉斑玄武岩、洋岛火。。。

Results revealed that the large side insulation of the stator bar in slot is available for ultrasonic pulse-echo testing; Coupling transducer on the surface of a practical stator bar could minimize the influence on the measurements of velocity, contributing no destructivity of the ultrasonic testing for stator insulation; The simultaneity of same velocity and higher attenuation can be used to detect insulation delamination from conductors; Compared with the wide sides of the bars in slot, the short sides of the bars near the exit from slot and the end bars had a same velocity and a higher attenuation; The velocity might be exactly measured on the shot sides of the bars near the exit from slot and the end bars, while the attenuation might not, which were examined though filed tests; V min decreased greatly and V av decreased slightly with the service time of the bars.

在实验室对线棒多种结构处的主绝缘和不同运行年数(未老化、16、18 和23年)线棒的主绝缘进行了低频超声反射法检测试验，并进行了现场试验，发现(参见 Hao et al， IEEE DEI， to be published)，槽部线棒的宽面绝缘不受换位绝缘的影响，比窄面绝缘更适合超声测量；线棒表面平滑的半导体层减小了耦合剂对超声测量的影响，实现了无损性；波速不变而声衰减减小可以检测线棒出现绝缘与导体脱壳缺陷；出槽口和端部线棒的窄面绝缘与槽部线棒的宽面绝缘相比，声衰减大而波速一致；现场试验验证了波速不受绝缘结构和现场测试条件的影响，而声衰减受以上因素影响很大(参见 Hao et al，中国电机工程学报， Vol.23 No.4)； V min 随运行年数明显减小， V av 随运行年数慢慢越小。

Ascospores are small, hyaline, and hat-shaped, 4.5-8 microns long by 2.5-5.5 microns wide, andthey accumulate in a sticky matrix at the end of the perithecium neck where they appear as a cream to pink ball or coil.

Unlike other molluscs, bivalves lack a radula and feature labial palps, which carry food from the gills to the mouth.

与其他软体动物不同的是，双壳贝缺乏齿舌，具有唇瓣，可将食物由鳃送到口部。

There were four newly hatched chicks, a day old - little specks of pulsating life no more than a mouthful; and he ate them ravenously, thrusting them alive into his mouth and crunching them like eggshells between his teeth.

窝里有四只刚出壳的小松鸡，才一天大——就像点点跳动着的生命之光，还不够他吃上一口；他把它们活活塞进嘴里，贪婪地大嚼大咽，像嚼蛋壳似地把它们在齿间碾碎。
