The Temperature fields in ladder-shaped sample of ZL105 alloy with sand mold and metal mold in solidification process were simulated by finite element method.

利用有限元方法，采用阶梯试块，对ZL105合金的砂型铸造和金属型铸造的凝固过程中的温度场进行了有限元模拟。

The relationships between strain and stress of several kinds of high strength fibers, such as Kevlar, Twaron and Dyneema were obtained, and the dependence of mechanical properties of fibers on the strain rate was gotten and explained from the microstructures and deformation mechanism of fibers. Then, the damage and failures of plates with the reinforcement of fibers under high velocity impacting were studied experimentally. Based on experimental results, a set of equations was presented to depicted the deceleration of penetrator. The dynamic response of fiber cluster and sandwich were simulated successfully with a new algorithm and code, which was developped by our group. The coupling effect of stress wave and thermal conduction could be considered with acceptable accuracy and CPU time.

其中，获得了以芳纶纤维为代表的7种纤维的动态应力应变关系，从材料微观机制解释了纤维束的应变率相关特征；得到了板材在高速冲击下的能量吸收机理，以及影响能量吸收机制转变的主要因素；发展了一种新型的原位光学测试技术，以之可以测量试件在冲击加载下的变形场及其演化，该技术除了在本项目应用外，还可以对剪切带的萌生演化、孔洞动态扩张规律进行较好的观察，以弥补相关研究中实验证据的缺乏；发展了含热传导的冲击动力学有限元程序，在侵彻、绝热剪切带、脉冲激光诱导结构破坏等问题的分析中得到了较好的应用。

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。
