During the high-voltage device design, the thick epitaxial layer LDMOS which is compatible with current technology was researched. This device used piecewise VLD and multiple region structure F reduce field layer. The using of the F reduce field layer effectively reduce the surface electric field of the device, shorten the length of its drift region, enlarge the choice of range of the ion implant dose of the P layer, and effectively restrain the disadvantageously affection on the breakdown voltage of the interface charge Qss.

在高压器件研究中对与现有工艺相兼容厚外延LDMOS进行研究，该结构采用分段变掺杂多区P~-降场层，有效降低器件的表面电场，缩短器件的漂移区长度，增大P~-降场层注入剂量的选择范围，并有效地抑制界面电荷Qss对器件耐压的不利影响。

It originated in the Hardanger region o f Norway 100's o f years ago.

正是在挪威100的哈丹格尔地区的起源年前。

We used direct PCR to isolate the rps7Ⅵintron region hosting the f copy of U17 snoRNA coding sequence from 49 fishes, which include 42 ostariophysan species plus 7 outgroup species.

我们测定了49种鱼类、67条rpS7 intron6序列，得到U17 snoRNA f copy，共计55个单倍型，包括42种骨鳔鱼类，7种外类群。

In this paper, in terms of diffusion equation of neutral gas in thermosphere and main ion-chemistry reactions in ionospheric F region, the diffusion processes of H2, H2O and CO2 and ionospheric response to released gases are investigated.

根据中性气体在热层背景中的扩散方程，考虑电离层F区主要的离子化学反应，研究了H2，H2O和CO2气体在电离层高度上的扩散过程和电离层对所释放气体的响应，计算了气辉的体发射系数和发射强度。

Additionally, airglow volume emission rates and intensity from the release at ionospheric altitudes are calculated The results show that the diffusion of released neutral gas in F region is very quick, and these gas molecules can cause a large-scale depletion of ionospheric electron density.

结果表明，中性气体在电离层高度上扩散非常迅速，在F区的一些高度上，主要正离子成分由O转变为其他分子离子，且在释放过程中伴随气辉发射，发射气辉的波长和特征与释放物质的种类有关。
