查询词典 F region

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。

Results: MC of tryptase immunoreactivity contain abundant F-actin ring that region of cytomembrane endothecium form a barrier of blocking tryptase liberation. Copious tryptase temporarily was stored in secretory vacuole, and small amounts tryptase was released from secretory vacuole for depolymerize of F-actin ring in cell.

As Longnan region of Gansu province is one of the largest and most important over-summering areas of Puccinia striiformis f.sp.tritici in China,the objective of this study is to determine the genetic structure of P.striiformis f.sp.tritici populations in this region.

甘肃陇南地区是小麦条锈菌最主要和最大的越夏区，本研究的目的是分析该地区的小麦条锈菌自然群体的遗传结构，探索其分子遗传变异规律。

A set of spectific primers was syn thesized according to HBV DNA sequence of Chinese strain, the whole X region was amplified by PCR method from the serum of 9 patients with chronic HBV infection , and then the PCR products were subcloned into pGEM Teasy vectors. Clones were randomly selected to be sequenced. Comparison of the cloned sequence was made to find the difference. After being compared, each sequence of selected clones is o f difference. The point mutation scattered through X region. Deletion mutations were detected in 19 clones of 37(51.4%), which caused different carboxyl endings of X protein. There is a hot region (after 123 aa code) where deletion mutation frequently happens.

以中国株HBV基因序列为依据，设计特异性多聚酶链反应引物，自9例慢性HBV感染患者血清中扩增HBV X基因，克隆入pGEM Teasy质粒，随机挑选克隆进行D NA测序以确定病毒的变异程度。37例测序结果提示来源于不同患者HBV X基因序列高度保守，但每个序列均不一致。X区除了存在广泛的碱基点替换突变外，序列的缺失突变占测序克隆总数的51.4％（19／37）；氨基酸缺失及移框突变多发生于123位氨基酸残基之后，可导致X蛋白多种羧基端形式。

The theoreti cal results show that in Al-rich region of the ordered TiAl alloy,the surplus a toms of Al which occupy the lattices of Ti will decrease the energy of the syste m,in favour of the stability of γ-TiAl phase,while in the Ti-rich region, the surplus atoms of Ti which occupy the lattic of Al will increase the energy o f the system,which disfavors the stability of γ-TiAl phase,and favors the formation of new phase.

理论结果表明有序的γ-TiAl相在富 Al区，多余的Al原子占据Ti的格点后，系统能量降低，有利于γ-TiAl相的稳定性，而在富Ti区，多余的Ti原子占据Al的格点后，将使所有的Ti原子的能量增大，使系统能量升高，不利于γ-TiAl相的稳定性，而有利于新相的形成。

Double layer tent at list layer foundation up increased 1 F well ventilated a little bit well inside the debt, main solution list the layer is inside the tent wall knot water problem(the human body ejects of the hot air cause), suitable cool season or cold region.3 F tent is at inside the debt add the 1 F cotton debt and strengthen the effect of keeping warm.

三层帐篷是在内帐上加一层棉帐，增强保暖效果。广大驴友在户外野营时，户外帐篷可配合户外床椅和睡袋同时使用，但是要根据目的地的环境选取合适的产品，比如寒冷地区要选择羽绒睡袋。户外活动结束后，要注意对帐篷和睡袋进行清理和保养。

Results Among 11 strains isolated from epidemic asthma-like pneumonia, 4 (36%) had extra six nucleotides inserted into the 3′end non-coding region of the F gene, whereas none of the F genes from 5 strains isolated from regular pneumonia had that insertion.
