The average Re-Os model ages determined by ICP-MS and NTIMS are (138.3±4.0) Ma and (141.0±3.6) Ma (2σ, n=9), the isochrone ages calculated with the ISOPLOT using the Model 1 are (138.6±2.9) Ma (2σ, n=9) and (141.6±1.9) Ma (2σ, n=9) respectively.

结果表明，该组样品的平均Re-Os模式年龄分别为(138.3±4.0)Ma和(141.0±3.6)Ma(2σ，n=9)和(141.6±1.9)Ma(2σ，n=9)，两者在目前水平下的误差范围内基本一致。

If deg f = n, then Rfc is an empty set. For all the functions of degree 2, Rf have at least 2n-1 vectors, when Rf is a linear subspace, the relationships between Rf and Lf are discussed . Boolean functions have no nonezero linear structure if and only if there are n linear independence vectors in f, the correlation of the vectors in ?

证明了，若degf=n，则R_f~c为空集，对于所有的二次布尔函数而言，均有R_f~c中的元素个数大于等于2~(n-1)，给出了R_f构成线性子空间时，R_f和L_f之间的关系，还给出布尔函数不含有非零线性结构的充分必要条件是ζ_f中含有n个线性无关的元素。

Through immunocytochemistry study, we found that the α3 and/or α5 subunits of nicotinic acetylcholine receptor are predominantly expressed in the oxytocinergic neurons. Our finding is quite different from the conclusion of the British scholar Dr. Mason's work in 1980s. We also found in this study that, the α3 and/or α5 subunits of N-AChR can also be expressed on the axons of oxytocinergic neurons, and these immunoreactive axons could be seen projecting to the median eminence and further to the posterior end of neurohypophysis. In the hypothalamus of the 7-day postnatal pup rats, the expression patterns of α3 and/or α5 subunits of N-AChR are similar to that in adult rats.

我们用免疫组化的方法发现，α3和/或α5型烟碱型乙酰胆碱受体(Nicotinic acetylcholine receptor，N-AChR)亚单位在大鼠下丘脑OT能神经元中呈优势性的表达，这与上世纪八十年代英国学者Mason类似工作的结论不一致；而且我们还发现α3和/或α5型N-AChR亚单位还表达在OT能神经元的轴突，此阳性免疫反应的轴突一直延续到正中隆起和神经垂体的末端；在新生7天大鼠的下丘脑，α3和/或α5型N-AChR亚单位的分布类似成年鼠。

On the classical theory, according to which D = for all values of N, the volume of employment is in neutral equilibrium for all -values of N less than its maximum value; so that the forces of competition between entrepreneurs may be expected to push it to this maximum value.

7按照古典理论，依据 D =Ф适用于 N 所有的取值这一规则，在 N 取小于其最大值的所有数值时，就业量处于中型均衡状态。因而能够预见企业家们相互竞争的力量可以使 N 达到最大值。

The structural parameters of PNHAAs, such as the the maximum N-NO2 bond length, the least N-N Mulliken population, the least negative charge on the nitro group (QNO2) and OB100, were studied to predict their relative stability or sensitivity (the easiness for initiating a detonation, high sensitivity means low stability).

通过研究PNHAAs的结构参数，如N-NO2最大键长、N-NO2键的最小Mulliken集居数、-NO2所带最小负电荷、氧平衡，预测了10个标题物的相对稳定性或感度(起爆的难易程度。感度越高，化合物的稳定性越低)。
