The average heterosis of spike number per plant and 1 000-grain-weight were high and obviously related to yield heterosis at 0. 01 and 0. 05 level, respectively; the average yield heterosis of F1 hybrids between common wheat and club wheat was 77. 19%(ranged from-2. 18% to 143. 42%), the average heterosis of spike number per plant and spike grain number were high and both was also obviously related to yield heterosis at 0. 01 level.

结果发现：小麦种间杂种在产量上具有明显的杂种优势，其中斯卑尔脱小麦与普通小麦所配的30个种间杂交组合产量杂种优势平均为109.24%(43.14%～187.96%)，单株穗数及千粒重平均优势较大且与产量优势的相关分别达极显著水平和显著水平；密穗小麦与普通小麦所配的30个种间杂种的杂种优势为77.19%(-2.18%～143.42%)，单株穗数和主穗粒数优势较大且与产量优势的相关均达极显著水平。

The primary reason for this is that bubbles coalesce with horizontal jet.

探讨了水平射流横向脉动的原因，发现气泡与水平射流的合并是水平射流横向脉动的主要原因。

In this article,based on the twolevel algorithm of selforganization and by applying the method of combinatorial investment ,we set up GMDHtwolevel algorithm security combinatorial investment prospective proceeds model.

以自组织理论两水平算法为基础，采用组合投资方法，在证券投资GMDH两水平算法预测模型的基础上，建立了GMDH两水平算法的证券组合投资预期收益模

The fundament of flat terrain phase effect and its removal are stated. The interferogram consists, for each pixel, of the complex conjugate product of two SAS images directly, which cant reflect the actual terrain change. The general phase trend in range can be considered as the phase generated by an ideally flat terrain and is often subtracted from the interferogram before further processing.

论述了水平地形效应产生原理及其消除方法，由于水平地形效应的存在使得两幅SAS复图像直接复共轭相乘得到的相位图不能直观地反映出实际地形的拓扑变化，所以在对干涉相位图进行滤波及相位展开处理前应当消除干涉相位图像的水平地形效应。

Proportion of compound and ureafertilizer is higher than average level of China;There is significant or very significantdifference of nitrogen and phosphorus application amount between rice or wheat bumper harvestfield and ordinary field.

江苏省的肥料投入水平高于全国和世界平均水平，全省有机氮占总施氮量的比例和全国相当，无机氮肥中复混肥和尿素的比例高于全国平均水平。

Using level-set method, mathematical representation for contimuum structures is proposed by means of the vector of level-set, and the general structure topology optimization can be expressed by a constrained functional minimization problem of a set of level set functions.

其次利用水平集方法将一般拓扑优化问题描述为一组水平集函数的约束泛函极小化问题，应用敏度分析，给出了此泛函极小化数值迭代求解公式，即水平集演化方程。

The main effect factors of the middle-transport efficiency are the level of transport supply and the structure of transport supply, the degree of transport modes technology progress, the degree of competition and cooperation among the transport modes or within the special transport mode, the degree of symmetry of the obligation of every transport mode and the regulation degree of the government. The main effect factors of the micro-transport efficiency are the market environment, the impetus mechanism, the response capacity and the level of transport organizing and technology progress.

本文提出宏观运输效率的主要影响因素是运输相关技术的发展水平和运输政策选择；中观运输效率的主要影响因素是运力供给水平与结构、运输方式的技术进步程度、运输方式之间及其内部的竞争与合作程度、各运输方式与社会受托责任的对称性程度、政府对各运输方式的管制程度；微观运输效率的主要影响因素是市场环境、运输企业的内部动力机制、运输企业的应变能力及运输企业的生产组织和技术进步水平。

Methods The levels of serum Hcy, folate acid and VitB12 were measured in 169 patients with cerebral infarction and 110 normal controls. The condition of carotid arteries was checked by color dopper flow image in CI group. The relationship between the level of serum Hcy and folate acid, VitB12 and CAA condition were analysed. The change of serum Hey level was observed after intervention treatment of folate acid and VitB12 for 4 weeks in CI patients with hyperhomocysteinaemia.
