查询词典 low-lying

Low-boiling phenols in low-temperature coal tar are important chemical raw materials. For the identification and determination of the individual phenol boiling below 210℃ in the low temperature coal tar, the methods of gas chromatography, liquid-liquid chromatography followed by ultra-violet analysis and fractional distillation followed by infrared analysis were evaluated and compared.

随着煤炼油工业的发展，煤焦油中的酚类，特别是低級酚，作为化工原料的利用很重要，我們应用(1)气液色譜法，(2)液液色譜与紫外光譜法結合及(3)精餾与紅外光譜法結合三种不同方法对210°以前的低級酚进行了各种异构体的成分分析，比較分析結果：三种方法对同一样品进行分析时，最大絕对誤差在2％以内，其中以气液色譜法最为快速，液液色譜法次之，精餾-紅外光譜法費时間較多；但后二种方法所得数据較完全。

Secondly, whole-chip ESD protection net is put forward. Input protection circuits, output protection circuits and circuits between high-voltage ground and low-voltage ground are decided on the base of structure and process of PDP drive chip. Moreover, the design of low-voltage VDD-to-VSS ESD protection circuits is detailed and the circuit is simulated with HSpice. Finally, the characteristic of high-voltage device after avalanche breakdown is simulated and analyzed with Tuprem-4 and MEDICI, and it is concluded that high-voltage device can stand high voltage and large current, so the low-voltage VDD-to-VSS ESD protection circuits can be applied to high-voltage VDD-to-VSS ESD protection.

随后提出PDP驱动芯片全芯片ESD保护网络的方案，并根据PDP驱动芯片的结构和制造工艺，介绍了输入部分、输出部分及高低压接口部分的ESD保护电路，然后重点分析了低压电源和地之间ESD保护电路的设计并用Hspice进行了模拟，最后使用Tuprem-4和MEDICI模拟了高压器件在雪崩击穿之后的电压电流和电场分布特性，得出高压器件本身可以承受一定的ESD脉冲，从而将低压电源和地之间的ESD保护电路应用到高压电源和地之间。

The result showed there existed significant differences among families in seedling growth, dry matter accumulation, leaf shape as well as root parameters at high and low nitrogen levels. Remarkable reduction in seedling height, dry matter accumulation, leaf and root parameters were observed under low nitrogen stress, whereas larger proportion of photosynthesis production was allocated into roots to promote nitrogen absorption. Family variation in seeding growth, leaf and root parameters were increased under low nitrogen stress in comparison with high nitrogen level, which would be benefit to discriminate superior L. chinense families with high nitrogen efficiency. Nitrogen efficiency of different L.

结果表明：不同氮素水平下，马褂木苗的生长、干物质积累、叶片和根系等性状皆存在显著的家系遗传差异；低氮胁迫将显著抑制马褂木苗叶片发育和根系生长，影响苗高生长和干物质积累，但低氮素水平下生产的光合产物则较多地分配至地下根系部分以促进对氮素的吸收利用；与高氮处理比较，低氮胁迫加大了苗木生长、叶片和根系参数等家系遗传分化，有利于鉴别高氮效率的马褂木优良家系。

Frigon was chosen as the experimental, According the quality of the heavy oil materials which have high oil content and low sericin content, technical conditions were initially set at the level of low pH value 、low temperature and enforced presoaking process.
