但由于煤的变质程度较低，煤质较差，加上逆掩断裂的挤压作用，使地层有效地应力较高、造成煤储层渗透性较差；再者，煤储层的含气饱和度较低，开煤层气的产出较为不利；但在构造的转折端及背科的倾伏部位，存在着微裂隙较发育的地应力低带，有希望找到煤层气勘探开发的有利区。

It can be seen that besides the realization of the common-emitter gain, thus current amplification, the common-base properties were also improved due to the reduction of the common-base leakage current. We have attributed the improvement of the common-base properties and the realization of the common-emitter properties to the enhancement of the electron injection due to the utilization of the V2O5 interfacial layer.

研究发现，V2O5界面修饰层的引入明显地减小了共基极漏电流，使器件的共基极特性得到了进一步的改善，同时也使器件表现了共发射极特性，实现了电流的放大，我们已经把共基极特性的改善和共发射极特性的实现归功于界面修饰层的引入提高了电子注入的结果。

Volcanic gas reservoirs of low permeability in the carboniferous of a basin are characterized by deep burial depth, complex genesis, many types, wide distribution and non-evident expressions in three-porosity log curves, as well as the variedvalues of density and compression wave of main four volcanic gas reservoirs (such as the basalt, andesite, dacite and rhyolite). So a number of effective methods based on three porosity log data cannot work in identifying the volcanic gas reservoirs of the carboniferous of the basin.

石炭系火山岩的低渗透气藏具有的埋藏深、成因复杂、类型多、分布广、三孔隙度曲线响应特征不明显等特点，并且主要的四种火山岩气藏：玄武岩、安山岩、英安岩、流纹岩的密度和纵波时差测井值差别较大，因此使基于三孔隙度测井资料的一系列识别气层的有效方法在该盆地石炭系火山岩气层的识别中无明显效果。

It is found that the utilization of BAlq3/Alq3 isotype heterostructure emitter further reduces the leakage current, leading the BAlq3/Alq3 isotype heterostructure-based devices to higher output current and higher common-emitter gain at the same operational voltage compared to the case of Alq3 as the emitter.

研究发现，同Alq3单发射极层结构的金属基极晶体管相比，BAlq3/Alq3异质结发射极层的使用进一步降低了器件的漏电流，使器件在相同的电压下表现了更高的输出电流和更高的共发射极增益，为进一步实现高性能金属基极晶体管提供了新的方法。

Lanthanides belong to the sixth cycle of the periodic table Ⅲ B family, are all solid metal, they are La, Ce, Pr, Nd, Pm, Sm, Eu, Gd, Tb, Dy, holmium, erbium, thulium, ytterbium, and lutetium were 15 kinds of metals and their periphery are two layers of electronic 5d16s2, while the peripheral third layer f orbital but never zero to 14, so the external electronic structure of 4f0-145d16s2, and therefore these elements in oxidation number are to 3, very close chemical properties, extraction, when it is difficult to separate them they are mostly multi-element mineral mix, more difficult to increase refining, and their atomic number of 57-71, one by one to increase the number of protons the nucleus, and thus extranuclear electron of gravity is also growing, so that atomic radius decreases with increasing atomic number Z, which makes lanthanides contraction, ionic radius is also reduced, which also makes Zr, Hf, Nb and Ta, Mo and W, the atom and ionic radius very close to each other they also determine a similar nature, resulting in difficult separation, also the tribe Ⅷ of the fifth cycle, ruthenium, rhodium, palladium, and the sixth cycle, osmium, iridium, platinum is very similar in nature, thus The six elements, said platinum group elements.

镧系元素属于周期表第六周期中ⅢB族，全部是固体金属，它们是镧、铈、镨、钕、钷、钐、铕、钆、铽、镝、钬、铒、铥、镱和镥共十五种金属元素，它们的外围两层的电子均是5d16s2，而外围第三层的f轨道电子却从零增加到14个，所以外围电子结构为4f0－145d16s2，而使这些元素氧化数均为＋3，化学性质极为接近，提炼时很难分开，它们的矿石又大多是多种元素混在一起的，更增加提纯难度，它们的原子序数为57－71，核内质子数逐个增加，因而对核外电子引力也不断增强，使原子半径随原子序数Z增加而减小，这就使镧系元素收缩、离子半径也缩小，这也使得Zr和Hf，Nb和Ta、Mo和W等原子和离子半径都很接近、也决定了它们彼此性质类似，以致难以分离、也使第Ⅷ族中第五周期的钌、铑、钯和第六周期的锇、铱、铂在性质上极为相似，因而称这六个元素为铂系元素。

The only source of light in the chamber—and with the topmost hatchway now closed, the only source of illumination at all—was a strange, glowing rectangle that shone against the far wall, a misty door painted on the wall in fitful yellowish light.

在这房间里，唯一的亮光——因为最上层的通道口现在关上了，也就是照在整个这第二层、第三层的光源——是在远处墙上闪光的、一个奇怪的矩形的发光体，是断断续续地黄色的光，在墙壁上描画出的一扇雾蒙蒙的门。

Our study is based on models and methods designed by S.G.

上述情况表明，我国监管层和学术界对该问题的重视不足，因此，对我国机构投资者的审慎性持股偏好进行实证研究，进而为机构投资者审慎投资理念的树立、为决策层、监管层的政策制定与监管实施提供参考意见，也就具有非常重要的理论价值和现实意义。
