Therefore,the reliability of data and image transmission is usually improved using hybrid ARQ error control scheme which is combined by ARQ and FEC.

因此为了提高数据及图像传输的可靠性，人们提出了采用ARQ与FEC相结合的混合ARQ差错控制方案。

The basic principle of the toughening and modifying on bismaleimide resin was introduced, the characteristics and the modifying effects of the toughening and modifying with thermoplastic resin, the combination of aromatic diamine and epoxy resin, organic silicone, allyl compounds, cyanate ester resin, the blends of three-dimensional braided carbon and Kevlar fabrics and so on were discussed.

介绍双马来酰亚胺树脂增韧改性的基本原理，论述了热塑性树脂增韧改性、芳香族二胺和环氧树脂相结合增韧改性、有机硅增韧改性、烯丙基系列化合物增韧改性、氰酸酯树脂增韧改性、三维编织碳纤维和凯夫拉纤维混合增韧改性等方法的特点与改性效果。

To avoid the shortcoming of magnification change with wavelength, which will cause the spectral image pixel registration error and provide inaccurate relative spectral signal strength in the classical diffractive optic imaging spectrometer, a novel hybrid refraction/diffraction telecentric optical system combining a diffractive lens with an achromatic lens system is presented, and the working principle is then established.

为了克服在传统衍射光学成像光谱仪中，衍射透镜的焦距随波长变化引起系统放大率随波长变化，从而导致光谱图像的像元配准误差，得到并不精确的相对光谱信号强度，提出了将衍射透镜与消色差透镜系统相结合的新型折/衍混合、二组元复合远心成像光学系统的技术方案，具体分析推导了该系统的成像理论。

建立了搅拌混合器的理论模型，并对其动力特性进行了数值分析，理论结果与实验结果相吻合。

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。
