In-situ energy dispersive X-ray diffraction measurements of enstatite have been studied by using diamond anvil cell with synchrotron radiation and laser heating in the range of 0~23 GPa and

采用同步辐射能量色散X射线衍射技术、激光加热技术和金刚石对顶砧高压装置，在温度为2000 K和压力为23 GPa的范围内，对采自地幔二辉橄榄岩中的顽火斜方辉石，进行了原位的高温高压能量色散X射线衍射测量。

We found that TN-C was abundant in the early heart development of rats, it was suggested that TN-C reference to the early heart morphogenesis; TN-X was poorly expressed in epicardium in hearts of ED11.5, implied it may have something to do with the formation of the coronary artery.

TN-C在大鼠胚胎心脏发育早期表达丰富，对心脏的早期发育有一定关系；而TN-X在ED11.5于形成血管的心外膜细胞周围表达，提示TN-X可能与心脏早期冠脉等血管的形成有关。

Under the locally uniform τ-Opial condition, using product topological net, a new convergence condition of X with locally uniform τ-Opial condition is obtained, and give the ergodic theorem and τ-convergence theorem of the almost-orbits for asympotically nonexpansive typesemigroups in Banach space X are given.

From the transform infrared spectroscopy and X-ray photoelectron spectroscopy spectra, the hydroxyl and ethoxyl groups of the silica sol drawn from partially hydrolysis and polycondensation between TEOS and MTES can react with PA6 precursor.

红外图谱和X射线光电子能谱分析结果显示，硅溶胶的羟基和未完全水解的烷氧基能够与PA6的前驱体发生杂化反应。X射线衍射结果显示，采用本实验方法制备出的PA6和疏水型PA6/SiO2有机无机杂化材均为α晶型，而DSC结果表明，PA6/SiO2有机无机杂化材料的熔点略高于PA6。

In eutherian mammals, XCI is thought to be triggered by the expression of the non-coding Xist RNA from the future inactive X chromosome3, 4, 5; Xist RNA in turn is proposed to recruit protein complexes that bring about heterochromatinization of the Xi6, 7. Here we test whether imprinted XCI, which results in preferential inactivation of the paternal X chromosome, occurs in mouse embryos inheriting an Xp lacking Xist.

在最新一项研究中，美国北卡罗琳娜大学研究人员用小鼠胚胎（研究人员用基因工程方法使这些小鼠在其未来失活的X-染色体上含有一个有缺陷的Xist基因）所做的新的研究工作显示，实际情况更为复杂。

Point X is the Exclave of point A and could represent point A according to point Z.

点X作为点A的外飞地，对于Z而言X等同于A
