Interstage coolers, finned after cooler, finned cylinders, finned aluminum heads, and fan-bladed flywheel produce cooler operating and discharge temperatures.

级间冷却器，翅片式后冷却器，翅片式气缸，翅片式铝制缸头，带有风扇的飞轮，均保证极低的运行和排气温度。

Ominant groups of large-sized soil animal included Microdrile oligochaetes, Coleoptera and Stylommatophora, ominant groups of middle-small-sized soil animal included Acarina and Collembola, ominant group of wetlands soil animal was Rhabditidia. Ominant species of Vertebrates were Eremias argus, Parus palustris hellmayri, Phylloscopus inornatus inornatus, Emberiza coides weigololi, Phoenicurus auroreus auroreus, Pica pica cenicea, Lanius cristatus lucionensis, Lepus capensis, Citellus dauricus and Eutamias sibiricus.

其中，优势类群和优势种类包括节肢动物的蜘蛛目、双翅目、同翅目、膜翅目；大型土壤动物的小蚓类、鞘翅目、柄眼目，中小型土壤动物的蜱螨目、弹尾目，湿生土壤动物的小杆目；脊椎动物的丽斑麻蜥，沼泽山雀、黄眉柳莺、三道眉草鸦、北红尾鸲、喜鹊、红尾伯劳，草兔、达乌尔黄鼠、花鼠等。

The effect of fin pitch, louver pitch, louver angle and etc. on the heat transfer and flow performance were studied.

本文研究了不同的翅片间距、百叶窗间距、百叶窗间距与翅片间距比值、百叶窗角度对百叶窗翅片传热和流动性能的影响。

The molecular phylogenetic trees indicated that Oedipodinae is a monophyletic group and this subfamily is a natural one, but Catantopinae and Acridinae are non-monophyletic. Oedipodnae is a relatively primitive group within the Acrididae, whereas the Oxyinae may have diverged later than Oedipodinae, but earlier than most other species of Acridide.

分子系统树表明：斑翅蝗亚科是一单系群，该亚科是一个合法的亚科，但斑腿蝗亚科和蝗亚科都不是单系群；斑翅蝗亚科在蝗科内是一个相对原始的类群，而稻蝗亚科比斑翅蝗亚科相对进化，比蝗科的其他亚科的种类相对原始。

Take the opportunity of this project, theoretical and experimental researches on the high-efficiency evaporator used in a large quick-freeze equipment have been done. The main work of experimental research is as follows:(1) Compare and analyze the influences of structural parameters on the heat transfer coefficient of an evaporator. The calculation results show that, under non-freezing conditions, the structure possessing the highest heat transfer coefficient is the one with circular fins, equilateral-triangle arranged small tubes and varying fin-spacing.

主要做了以下几方面的试验研究工作：(1)对不同翅片形状、管径大小、翅片管排列方式，以及是否带波纹等结构参数对蒸发器传热系数的影响进行了比较分析，得出在不结霜工况下，具有最高传热系数的蒸发器结构是圆翅片小管径正三角形排列等节距结构的结论。

When the saturated vapor of pure R11 or R113 was condensed on the PF tubes under free convection conditions, the HTCs (based on the outside area of the base tube, the same be1ow) were 14 to 20 times those of the smooth tube because the condensate surface tension made the condensate film on fin surfaces thin and the rough saw-toothed fin surfaces disturbed the boundary layer in the condeneate film.

纯R11、R113的饱和蒸气在大空间花瓣形翅片管上冷凝时，由于凝液的表面张力将翅片表面上的液膜拉薄以及粗糙的锯齿形的翅片表面扰乱了凝液膜内的流动边界层，传热膜系数（以坯管外表面积为基准，下同）是光滑管的14—20倍。

Artificial neural network classifiers are respec-tively built by wingbeat waveformti me series and wingbeat frequencies.

研究中分别以蚊虫翅振频率和翅振波形建立人工神经网络，结果发现以翅振频率为特征值的神经网络的识别准确率高。

Clade Ⅰ consists of the species of Pyrgomorphidae and Chrotogonidae, Clade Ⅱ consists of the species of Pneumoridae, Clade Ⅲ consist of species of Pamphagidae and Clade Ⅳ contains species of Catantopidae, Oedipodidae, Arcypteridae, Gomphoceridae and Acrididae.

三、在对斑翅蝗科系统发育的研究中，我们共测定了斑翅蝗科4亚科15种蝗虫的16S rDNA序列片段，并从GenBank中下载了斑翅蝗科6种、其它蝗科9种的16S rDNA相应序列片段，然后对这共计30种蝗总科昆虫的16S rDNA序列片段进行了同

This one mode pays close attention to network credence foundation of the businessman very much.

这一模式非常关注商人的网络信用基础。
