BMSCs were isolated from adult rats by modified bone marrow culture method. BMSCs were inoculated in basic medium containing 10%fetal bovine serum, high glucose DMEM, 100 U/L penicillin, 100 U/L streptomycin and 2 mmol/L glutamine in the control group. BMSCs were inoculated in conditioned medium (basic medium, 10 mmol/L β-glycerophosphoric sodium, 10-7 mol/L dexamethasone, 50 mg/L vitamin C).

通过改良的骨髓培养法分离成年大鼠骨髓间充质干细胞，对照组以基础培养液(10%胎牛血清+高糖DMEM+100U/L青霉素+100 U/L链霉素+2 mmol/L谷氨酰胺)培养，实验组用条件培养液(基础培养液，10 mmol/Lβ-甘油磷酸纳，10-7 mol/L地塞米松，50 mg/L维生素C)进行诱导培养。

The U-Pb and Pb-Pb isotopic dating of zircons provided the ages of 447-462Ma representing the ages of peak granulitic metamorphism. The U-Pb dating of detrital zircons from aluminum-rich gneisses yielded older upper intercept ages which reflect the times of older materials derived from sourse rocks of the gneiss protoliths.

岩石中变质锆石的U-Pb及Pb-Pb同位素测定获得447-462Ma的年龄值，代表其麻粒岩相的变质作用时代，富铝片麻岩中含继承组分的锆石还获得较老的上交点年龄，它可能代表其沉积岩原岩源区的年龄。

By adding appropriate copper stearated, melamine, the PVC U products have excellent properties of pulverization preventing and ageing resistance such as inoxidizable, uvioresistant, weatherproof, ageing resistant properties, and excellent heat stabilization.

在户外用PVC U型材配方中加入适量的硬脂酸铜和蜜胺，既可防止PVC U表面的粉化现象，同时又能抑制其耐热老化性能的降低。

Glaciers carved the two valleys that join the Shuzheng Valley—the Zechawa and the Rize, which climb to around 10,000 feet—into the classic U shapes one knows from Yosemite, Jiuzhaigou's "sister" park in the United States, with walls that discourage casual scrambling yet do not tower severely enough to distract from the extraordinary limy beauty of the modest waterways underneath.

冰川雕刻成的两座峡谷，则查洼和日则，高达10000英尺，它们连接起中间的树正谷，形成了典型的U字形（九寨沟的&姐妹&公园，美国的约赛米蒂国家公园的U字地形为人所著称）。两边高耸的峭壁会使想随意攀爬一下的游客知难而退，但这峭壁并不会使人们分心，底下并不宽大的水道的超凡脱俗的美才醉人。

All parts that will contact ethanol in the divece such as condensor,buffer tank,coolingsnake pipe ar e made of stainless stwwl in order to guarantee that the finished product,ethanol ,is not polluted,Nodel Wstill may use disassembled U type heating pipe.When maint enance,it can be removed out of the still,So it is very convenient to clean the o uter wall of heating pipe and the inner wall of still.

本装置中凡接触酒精的设备部分，如冷凝器，稳压罐，冷却蛇管等均采用不锈钢，以确保成品酒精不被污染。W型之蒸馏釜采用可拆式U型加热管，在检修时可将U型加热管移出釜外，便于对加热管外壁及蒸馏釜内壁进行清洗。

Methods Based on the analysis for the inner structural CL images of zircons, the U-Pb ages and Hf isotopes of zircons from the host granites, mafic microgranular enclaves and diorite dykes have been discussed using in situ zircon analysis of the LA-ICPMS and MC-ICPMS.

在锆石内部结构的CL图像研究基础上，用LA-ICPMS和MC-ICPMS测定锆石U-Pb年龄及Hf同位素组成，探讨寄主花岗岩、暗色闪长质包体及及围岩中闪长质脉体锆石U-Pb年代学及Hf同位素组成特征。

The results of high precise zircon U-Pb isotopic ages present the orders of intrusions in Tongling region: granodiorite→pyroxene diorite-pyroxene monzodiorite→quartz diorite-quartz monzodiorite.

高质量锆石U-Pb同位素~(206)pb/~(238)U加权平均年龄结果表明铜陵地区中酸性侵入岩的成岩序列为花岗闪长岩→辉石闪长岩→石英闪长岩。

If G satisfies max{dG(u,dG}≥ n/2 for each pair of nonadjacent vertices u,v ∈ V, then G has a fractional k-factor.

若对于每一对不相邻的顶点u，v∈V都有max{dG，dG}≥n/2，则G有分数k-因子。
