It uses AMESim to Model and Simulate the servo-cylinder hydraulic system of the straightening machine and discovers the reasonable pr essure of overflow valve between the servo valve and Rodless cylinder servo cavity.

根据油缸压力信号，采用 AMESim 对矫直机伺服缸液压系统进行建模与仿真，找出伺服阀出口和伺服缸无杆腔之间的溢流阀的最合理压力。

At same time it collects the pr essure signal of Servo-cylinder, it finds that the overflow valve pr essure sets too high between the servo valve and Rodless cylinder servo cavity, Tanks should not stress-free cavity under unloading, According to the fuel tank pr essure signal.

摘 要：本文针对某热轧厂横切线上的主要设备矫直机在矫直高强度，厚规格产品时，当负载受到外扰动时，矫直机传动轴经常断，工作辊轴承经常损坏现象，于是对伺服缸压力信号进行采集，发现装在伺服阀出口和伺服缸无杆腔之间的溢流阀压力设置过高，油缸无杆腔压力不能卸荷。

It is shown that the ADFVLN, which has lower losses, high off-design performance and reliability, is superior to the vaned nozzle as the first stage and it also has more advantages than the early AFVLN, such as lower losses and less skewed boundary layer near the inner ring ect..

研究表明，这一新型轴流无叶喷嘴不仅具有原来同类喷嘴的优良性能，而且双出口结构和内环旋转的特点，使其流动效率明显提高，并省去两块隔板，缩短了机组的轴向尺寸，具有较高的工业应用价值。

Although the flow in the vaneless nozzle is three-dimensionat, it is two-dimensional in viscous sub-layer.

通过对喷嘴出口湍流流场的分析，认为三维湍流边界层的粘性底层内流动仍是二维的，因此可以采用可靠的二维壁面律。

The flowfield and performance of a centrifugal compressor was predicted and analysed, which was composed of a Krain's impeller and two types of vaneless diffuser specially: one was constant area vaneless diffuser and the other was the straight-wall. The results show that the efficiency of the straight-wall vaneless diffuser is obviously lower than that of the constant area, and a separate flow occurs nearby the exit of the centrifugal impeller with the straight-wall diffuser. However, the type of vaneless diffuser has little influence on the aerodynamics performance of the centrifugal impeller. Finally, it is suggested that the constant-area vaneless diffuser should be selected as the downstream extended area of the centrifugal impeller during the prediction for the centrifugal impeller.

对Krain叶轮后带等面积与直壁两种形式的无叶扩压器离心压缩机内部流场进行了计算与分析，结果表明：直壁型无叶扩压器离心压缩机的效率低于等面积无叶扩压器离心压缩机的效率；直壁型无叶扩压器使得叶轮出口的流动出现分离；扩压器的形式对离心叶轮的整体气动性能影响并不大；在进行离心叶轮数值研究时，叶轮后的延伸区最好采用等面积无叶扩压器，以尽量减小无叶扩压器所引起的计算误差。

The GLCC is one kind has leans the bevelling to the entrance and the gas, the liquid exportation hangs the ascending pipe.

After this flow pattern transformed into a flow pattern with thermal chocking at the combustion chamber exit and with a pseudo-shock wave developing in the inlet diffuser.

之后，在燃烧室出口出现热拥塞现象、在进气道扩压段产生伪激波流态。

It can be concluded that, when the jet is injected at positive angles, the initial section of the jet increases and the region affected by the jet decreases in the vertical direction; moreover, the circumfluence toward the jet exit becomes more obvious, and the separation events in the lee of the jet weaken. When the jet is injected at negative injection angles, it disarranges the flow upstream and the curvature of jet trajectories varies smartly along the flow direction.

结果表明：射流正向倾斜入射时，射流起始段增加，在垂直方向对主流场的影响区域减小，射流喷口上游位置处的&孔吸流动&更为明显，射流出口下游背风侧的分离现象逐渐减弱；射流反向倾斜入射，对上游流场的扰动增加，射流在弯曲段内曲率变化大。

Knowing the absolute enthalpies at the entrance and exit of the desiccant wheel and assuming equivalent mass flow rates permits

So far, most research about vectored nozzles is numerical simulations of internal flow field and manuverbility. However, research about their infrared properties, especially systematically research about spectral properties is very sparce.

目前国际上对矢量喷管内流场的数值计算，矢量喷管的机动性能的研究比较多，然而对矢量喷管红外辐射特性的研究非常少，特别是系统地研究矢量喷管壁面和出口平面的光谱辐射特性方面的工作特别少。

Cynanchum Lingtai apricot production in the average weight 65 grams, the brightly-colored fruit, juicy rich, sweet-sour taste, sweet from the nucleolus, when the late Qing Dynasty famous Shaanxi, Gansu provinces, the Qing imperial court Tongzhi tribute for years.

灵台生产的牛心杏平均单果重65克，果实色泽鲜艳，汁多味浓，甜酸适口，离核仁甜，清末时就驰名陕、甘两省，清同治年间曾为朝廷贡品。

Chenopodium album,Solanum nigrum, and Amaranthus retroflexus were very susceptible to the herbicides. Polygonum persicaria and Abutilon theophrasti were relatively less susceptible to the herbicides, and Lycopersicon esculentum was not susceptible to it. The relationship between reduction rates of weed biomass and PPM values of weed leaves 2,4, and 6 days after treatment was established.

供试的6种杂草对该混剂的敏感性存在显著差异：红心藜Chenopodium album、龙葵Solanum nigrum和反枝苋Amaranthus retroflexus对该混剂最敏感，ED90值分别为47.65、71.67和29.17g/hm2；春蓼Polygonum persicaria和苘麻Abutilon theophrasti敏感，ED90值分别为96.91、114.20g/hm2；而番茄不敏感。
