There are two kinds of spinels in a granulite terrain of Yushujgou, South Tianshan Mountain. One occurs in the intermediate and basic granulite units and is characterized by enriched Al and poor Cr, belonging to Al_spinel. In thin sections it shows dark green color and subhedral to anhedral form, and coexists with other metamorphic minerals, suggesting a neogenic metamorphic mineral of granulite facies. The other occurs in the adjacent ultramafic rock unit, belonging to Cr_spinel. In thin sections, it is dark brown in color and is scattered among olivine, clinopyroxene and orthopyroxene as irregular grains, indicating a stable residual mineral in the process of granulite facies metamorphism.

新疆榆树沟麻粒岩地体中发育两类尖晶石：一类见于中、基性麻粒岩体中，其化学成分富 Al贫 Cr ，属铝尖晶石，镜下为深绿色，呈半自形至他形粒状，与其它变质矿物共生，表现为麻粒岩相的新生变质矿物；另一类发育在空间上与麻粒岩体紧密相邻的超镁铁质岩体中，为铬尖晶石，镜下为深褐红色，呈不规则粒状分布于橄榄石、斜方辉石和单斜辉石之间，为麻粒岩相变质过程中稳定的残余矿物。

Hystrix at 25℃(S. pistillata: 0.0126±0.0045 g/g*day; S. hystrix: 0.0253±0.0081 g/g*day) were significantly higher than those at 28℃(S. pistillata: 0.0066±0.0027 g/g*day; S. hystrix: 0.0083±0.0046 g/g*day) and 20℃(S. pistillata: 0.0058±0.0014 g/g*day; S. hystrix: 0.0047±0.0022 g/g*day).The mean growth rates of S. hystrix in two mesocosms at 25℃ were similar and significantly higher than those of S.

结果发现，萼柱珊瑚和尖枝列孔珊瑚群体的平均生长率在25℃(萼柱珊瑚：0.0126±0.0045 g/g*day；尖枝列孔珊瑚：0.0253±0.0081 g/g*day)皆显著地高於28℃(萼柱珊瑚：0.0066±0.0027 g/g*day；尖枝列孔珊瑚：0.0083±0.0046 g/g*day)和20℃(萼柱珊瑚：0.0058±0.0014 g/g*day；尖枝列孔珊瑚：0.0047±0.0022 g/g*day)，显示25℃较适合这两种珊瑚的生长。

Spinel lherzolites vary from 850°to 1050℃. The number of spinel lherzolite sample increases at 850℃ and decreases at 1050℃ sharply. The rarity of spinel lherzolite between 900° 950℃ has a particular significance. Spinel-garnet lherzolites have higher temperatures (1050° 1100℃) than the spinel lherzolites.

尖晶石二辉橄榄岩的平衡温度主要介于850°-1050℃之间，850℃和1050℃分别代表了尖晶石二辉橄榄岩的数量剧增和锐减的两个温度界线，900°-950℃之间的尖晶石二辉橄榄岩的缺乏具有特殊的意义；尖晶石-石榴子石二辉橄榄岩的平衡温度介于1050°-1100℃之间。

Xin Hua Hospital,Tongzhou District,Beijing101100. Objective To find an easy and effective therapy to cure patients with pulp necrosis or chronic pe-riapical periodontitis.Methods 184patients（age18～60）with184infected permanent teeth were randomly divided into two groups.The experimental group was filled with the VITAPEX paste plus gutta percha.

目的 针对牙髓坏死、慢性根尖周炎病例，探求简便有效的治疗方法方法在临床选择18～60岁的牙髓坏死、慢性根尖周炎病例184例，184颗患牙，随机分两组，第一组采用VITAPEX糊剂加牙胶尖一次法根充治疗完成。

随机选择需行根管治疗术的单根管恒前牙、双尖牙 2 30颗，分为A、B两组，A组采用RootZX 根管测量仪测量根管长度，根管预备后，根管充填时加试尖步骤，调试出最适主尖后侧压充填根管，摄牙片

Thus the statute of king Edward IV,4 which forbad the fine gentlemen of those times to wear pikes upon their shoes or boots of more than two inches in length, was law that favored of oppression; because, however ridiculous the fashion than in use might appear, the restraining it by pecuniary penalties could serve no purpose of common utility.

这样来看，国王爱德华四世（1442–1483）的那条法令——禁止那个时代低于贵族的绅士在他们的鞋或靴上装有超过两英寸的尖刺，是一条有助于压迫的法律；因为，无论这种流行看起来多么荒谬，通过罚金来约束它无益于任何共同效用的目的。
