  rotation pattern
The internal deformation band structure as well as the crystal lattice rotation pattern near the bicrystal grain boundary were characterized and found to give greater rates of work hardening in the neighborhood of the grain boundary.
      
When the rotation pattern is unknown, it needs to be considered using a particular sequence of Euler/Cardan angles to represent joint rotations.
      
The calculated geometrical rearrangements correspond in time to observed restructurings of the corona, the interplanetary field, and the solar rotation pattern.

In this paper, the approximate formula which describes the EPR rotation pattern is deduced. Take the vacancy-oxygen pair and the vacancy-phosphorus pair two kinds of defects for example. According to the principle value and the principle axis direction of g and A published by the documents, the calculated EPR rotation pattern is consistent with the published data on the whole.

本文推导出描述EPR旋转花样图的近似公式,并以硅中空位—氧对和空位—磷对两种缺陷为例,根据文献发表的g和A的主值及主轴方向,计算它们的EPR旋转花样图,与文献上所发表的基本一致。

Rotation and fertilizer application have the apparent effects on yield increase. In the case of no fertilizer application,and in comparison of rotation and continuous cropping, the annual average yield increase by 7 rotation patterns is from minus 11 to 143 jin/mu. In comparison of treatment of fertilizer application with no fertilizer application, the annual average yield increase in each treatment of rapeseed cake application, high, medium and low fertilizer application is 171 jin/mu, 160...

Rotation and fertilizer application have the apparent effects on yield increase. In the case of no fertilizer application,and in comparison of rotation and continuous cropping, the annual average yield increase by 7 rotation patterns is from minus 11 to 143 jin/mu. In comparison of treatment of fertilizer application with no fertilizer application, the annual average yield increase in each treatment of rapeseed cake application, high, medium and low fertilizer application is 171 jin/mu, 160 jin/mu, 128 jin/mu and 109 jin/mu respectively. In wheat and pea rotation, wheat and rape rotation,there is less input so that land use and land betterment are rational. The major wheat crop consists of the principal portion of total yield with high economic returns.This approach should be used according to local conditions.In the case of annual average wheat yield of 384 jin/mu, and sufficient other nutrient elements in soils, the annual average, wheat yield per mu can obtain its yield index of over 500 jin when 11 jin of N fertilizers and 5—6 jin of P_2O_5 fertilizer are applied.

轮作和施肥均有显著的增产作用。在不施肥的条件下,轮作与连作相比,七个轮作方式的年平均增产量为-7—143斤/亩。施肥与不施肥处理相比,施油饼、高肥、中肥和低肥各处理的年平均增产量(斤/亩)分别为165、116、94和47。麦豆轮作和油麦轮作投入少、土地用养合理、稳产、主作小麦占总产的比重大、经济效益高,应因地制宜地利用。在年平均亩产量384斤的条件下,在其它营养元素不缺少的情况下,每料作物亩施N11斤,p_2o_55—6斤,即可实现年平均亩产小麦500多斤的产量指标。

The condition,treatment and method of the grass and field crops rotation experiment,as well as the productivity and benefit of different rotation patterns were introduced in the paper. The experiment results indicated that the grain-legume rotation should be used as a major rotation pattern in the basic farmland because the higher and more stable yield was obtained comparing with other treatment. The high above-ground biomass and high ratio of output to input of energy were achived from the pasture-crop rotation mainly including alfalfa, therefore, it could be developed as a constituent part of cropping systems according to local condition in the region. The problems concerning biomass,yield,adaptability to environment,response to chemical fertilizer and after effect of pasture- grain rotation were discussed also in the paper.

文章介绍了草田轮作试验布设概况及不同轮作方式的生产力与效益。试验表明:四区粮豆轮作:豌豆—春小麦—春小麦—糜(谷)子的粮食产量较其他轮作高而稳定,应作为当前基本农田的主要轮作方式;以苜蓿为主的草粮轮作,其生物量、产能及能量产投比都较高,拟作为农田种植业的重要组成部分,因地制宜地加以发展。根据试验结果,讨论了草粮轮作的生物量、产量、适应性、对化肥的反应以及后效等方面的问题。
