在Δu 大的情况下多重平衡态是否存在留待以后研究。

The zircon grains separated from the syenogranite sample in the Chahayan pluton show generally euhedral form with fine oscillatory zoning on their CL images, and high Th/U ratios (0.32-1.12), which exhibit the features of magmatic zircons.

岩体中锆石呈自形晶，发育细微振荡生长环带，显示高的Th/U值(0.32~1.12)，表明锆石的岩浆成因。

Seeds typically U-shaped or falcate, 8-9.5 mm.

种子通常U形或镰刀形的，8-9.5毫米。

Thus, the vast majority of time the u-joint is straight or only slightly flexed.

因此，绝大多数时间的U -联合是直线或稍微弯曲。

In thenext section, it utilizes DEA method to evaluate governance efficiency. There exist a mostoptimization capital structure in 51%, and a upper limitation of frim value in 0.13, which isinverse U sharp relationship with governance efficiency.

最后，进一步利用非参数相对效率方法，评价处于成长和成熟两个不同阶段农业上市公司的融资结构的治理效率，并获得有效治理状态下的最优狭义资本结构为51％水平；农业上市公司内在价值的上限在0.13左右，且与融资治理效率关系是倒U关系等结论。

Non-parametric Mann-Whitney U -test showed that there was no significant difference between male and female hosts on the species richness and abundance of total ectoparasites, chigger mites, sucking lice, fleas or gamasid mites.

U 检验表明，体表寄生虫、恙螨、吸虱、蚤类和革螨的数量和物种数在雌雄宿主体表间的差异无统计学意义。

Summarized the experience of U-type reverse gastroscope biopsy so as to enhance the diagnosis level of gastric fundus disease.

总结U型反转胃镜方法活检胃底病变的经验，提高胃底病变的诊断水平。

In this paper, we report our structure observation and U-Pb zircon ages of the two types of Triassic granites, and use these data to place chronological constraints on the tectonic evolution of the western Kunlun orogenic belt. The gneissic garnet-bearing granite was crystallized at 241 Ma, whereas the horblende-bearing granite emplaced at 228 Ma.

对西昆仑西段海西晚期两类构造特征完全不同的花岗岩露头尺度的观察、锆石U-Pb定年结果表明，一类含石榴子石片麻状花岗岩形成时代为240.5±1.8 Ma，表现出同造山过程中的花岗岩变形特征；另一类块状含角闪石花岗岩的年龄为228.2±1.5 Ma。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。
