温度不均匀分布

Furthermore, the relation between the moving period of the nuzzle and the isothermal characteristics of the heating object was obtained.

像这样的射流冲击加热装置，如果射流喷嘴宽度小于被加热物体的宽度，那么被加热物体的温度分布将会不太均匀…。

The morphologies and purity of CNTs obtained at different temperatures in the range of 700℃-850℃ were investigated. At the optimal decomposition temperature 770℃ the pure product shows uniform diameter, small curvature and high yield. The more important thing is that there is no unremovable oxide support in the products, which represent the excellent properties of MCNTs.

发现在最佳裂解温度770℃下制备的多壁碳纳米管直径分布均匀、曲率小、纯净、产率高，更重要的是不具有难处理的氧化物（如Al2O3）载体，充分体现了碳纳米管作为载体的优越性。

These five zones are as follows: the zone of the reaction synthesis of TiC, the zone of reaction completion, the zone of the growth and homogenization of TiC, the zone of ideal structure and the zone of coarsened TiC particulates.

结果表明：适当提高合金熔体的等温反应温度并选择理想的反应时间，可获得尺寸细小、数目较多且分布均匀的原位TiC颗粒；当合金熔体中TiC的合成反应基本完成时，凝固速度对组织中TiC颗粒的数量和尺寸的影响不是很大。

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。
