两三个

The creative aspects in this dissertation are summarized as below:(1) In relation to the BJT/FWD integrated device, two new ideas are proposed. One is to extend the diode anode metalization to the region between the BJT and the diode regions to realize a Schottky contact to release the influence of the BJT region on the diode switching performance.

本论文创造性的工作包括以下三个方面：(1)在双极功率三极管与续流二极管构成的集成器件方面，提出了两个创新点，一个是将集成二极管的阳极金属化延伸到二极管和功率三极管之间的区域形成肖特基接触，以此来减弱同一芯片上的功率三极管区域对续流二极管开关速度的影响；另一个创新点是将集成二极管的结构由传统的PiN结构替换成含有肖特基接触的MPS结构。

The phenotypic mean values for the three populations and the midparental heterosis values for the two backcross populations were used for quantitative trait locus mapping and analysis, the genetic basis and correlations betweent the traits were analysed.

Erve growth factor can combine with its" receptor (one of tyrosine protein kinase receptor coded by proto - oncogene tyrosine kinase, TrkA), Causing the molecule of receptors to gather on the cell surface, and the tyrosine protein in cytoplasmic domain may be activated, three tyrosine base in the kinase domain of its" receptor and two tyrosine base at other domain be phosphated, thus, phosphated tyrosine receptor kinase became the bracket which absorb all kinds of connective proteins and kinases.

GF与其酪氨酸受体激酶受体(由原癌基因trk编码的一种酪氨酸蛋白激酶受体，TrkA)相结合，引起受体分子在细胞表面发生二聚体化，然后受体细胞内结构上酪氨酸活性被激活，使受体自身结构中位于激酶结构域的三个酪氨酸残基及在此结构域外的两个酪氨酸残基发生自身磷酸化，这样，磷酸化的酪氨酸受体激酶A便成为吸收各种连接蛋白质和酶的支架。

Located about 100 million light-years away in the constellation Piscis Austrinus, the galaxy interaction may ultimately lead to the three reforming into two larger star cities.

这三个星系位于南鱼座，离我们约1亿光年，引力相互作用最终可能导致三者合并为两个大星系。

In the investigatedcomposition region,two ternary phase:Nd3(Fe1-xVx)29(x=0.066-0.095)and Nd(Fe1-xVx)12(x=0.125-0.167),one pseudobinary phase:Nd2(Fe1-xVx)17(x=0.000-0.066)areobserved at 1323K.

在1323K温度时观察到三个化合物，其中有两个三元化合物：Nd3(Fe1-xVx)29(x＝0.066-0.095)和Nd(Fe1-xVx)12(x＝0.125-0.167)，和一个二元化合物固溶体Nd2(Fe1-xVx)17(x＝0.00-0.067)。

METHODS 104 cases of primary motar teethes were selected and randomly divided into the upper jaw and lower jaw groups according to their position. Using the 2% glutaraldehyde pulpotomy, the curative effects of three and six months after operation were comparatively analyzed with following up the patients.
