In this paper, different leaching procedures were used for the chondrules and chondrule fragments of Semarkona, and the U-Th-Pb compositions of leachates and residues were analyzed by TIMS method. The residues normally give higher 206Pb/204Pb ratio, suggesting higher radiogenic Pb compositions. These residues form a Pb-Pb isochron, and give an age of (4566.9±5.8) Ma with MSWD of 26, consistent to the weighted average age of 207Pb/206Pb model ages.

在本文中，对Semarkona中球粒用不同的化学浸洗流程，并测定浸洗溶液和残渣中U-Th-Pb同位素组成，其中浸洗后的残渣均给出相对较高的206Pb/204Pb比值，表明其中含有较多的放射成因Pb同位素组成，这此残渣构成Pb-Pb等时线，给出年龄为(4566.9±5.8)Ma，MSWD=26，与207Pb/206Pb模式年龄在误差范围内一致。

The tetrazine high-nitrogen energetic material s are new kinds of ones researched and reported widely at home and abroad in recent years.

四嗪环是一种含氮质量分数达68.3%的六元氮杂环含能基团，是设计高能钝感含能材料中非常有效的结构单元；四嗪类高氮含能材料也是近年来国内外研究和报道较多的一种新型含能材料，部分具有生成焓高、热稳定性好和感度较低等特点。

BACKGROUND: Acellular amniotic membrane used widely in treating ocular surface disease as well as extensive burn wounds due to its low antigenicity and excellent histocompatibility. However, it is poorly understood whether it can be used in repairing urethral defects.

背景：脱细胞羊膜的抗原性低，组织相容性好，在眼科眼表疾病及大面积烧伤中有较多的研究和临床应用，但在泌尿系统中的组织缺损修复较少报道。

But in familiar male-male pairs,there are less aggressive and more amicable behaviors than unfamiliar male-male pairs.

但当两只熟悉的雄鼠相遇时，则比陌生雄鼠相遇表现出较多的喜好行为和较少的攻击行为。

Wilkes certainly seemed to do everything right: He took time to study the line, didn't rush the lead, and wore a helmet. He does note that because the climb is somewhat obscure, the rock is a little scruffier than on Red Rocks' more traveled routes.

Phil Wilks 看起来所有动作都没有问题，他有花时间来观察路线，没有急冲冲地绑了绳子就开始攀爬；他有戴著岩盔；他也知道这个区域是一般人比较不熟悉的地方，而此处的岩壁相较於 Red Rocks 其他区域会有较多的尘土。

Therefore in these two techniques, when we want to avoid the blockers defense, using one-foot take off spike can get better effect.

因此就排球比赛中两种起跳动作的运用时机而言，在以拉开进攻点，摆脱对方拦网者的封锁时以横移较多的单脚起跳扣球动作效果较佳。

In the condenser of the air-condition,the lower velocity position such as head more sludge deposition existed.

在中央空调的冷凝器中，封头等流速较低的部位将有较多的污泥沉积。

Instead, hushed passengers type away on their handsets or read mobile-phone novels (written Japanese allows more information to be displayed on a small screen than languages that use the Roman alphabet).

所以在列车上，乘客们会安安静静地用电话发送信息或是读掌上小说（与使用罗马字母的其他语言相比，日语文字可以在较小的屏幕中显示较多的信息）。

Restriction mechanism for fiber elongation of Lil mutant grown in Held There were abnormities of ultra structure in 9 DPA fibers of Lil mutant whencompared with wild type: thinner cytoplasm, less functional organelles such as Golgi body and endoplasmic reticulum, ect, and more starch grains.

在田间条件下突变体纤维伸长受抑制的原因与野生型比较，突变体开花9d后的纤维细胞在细胞形态学上存在异常：细胞质染色较浅，各种功能性细胞器如高尔基体、内质网等少，有较多的淀粉粒等。

With Death guitarist Schuldiner adopting vocal duties, the band made a major impact on the scene.
