Objective To explore the effects of forepaw sensorimotor deprivation in early life on hippocampus-dependent spatial reference learning and memory in rats.

目的 研究生命早期前爪感觉和精细动作剥夺对大鼠海马依赖性空间参考学习记忆能力的影响。

The deprivation of forepaw sensorimotor in early life has no significant effect on the locomotor activity and exploratory behavior of rats, but can impair the spatial reference learning and memory.

生命早期前爪感觉和精细动作剥夺，对大鼠自发性粗大运动能力无明显影响，但可损伤其空间参考学习记忆能力。

Rats of postnatal day 13 (PN13) in experiment group were selected, and models of forepaw sensorimotor deprivation were established by microsurgical technique.

取13日龄（PN13）实验组大鼠，运用显微外科技术建立幼鼠前爪感觉和精细动作剥夺模型。

Using difference method, the first-order and the second-order differential equations of fractional derivative can become the first-order ordinary differential equation, and the high precision direct integration can be used for the solution.

所论方法首先引入差分格式，将含有分数阶导数的一阶和二阶微分方程变为一阶的常微分方程，然后再用精细积分方法逐步积分进行求解。

This paper has introduced briefly the good and shortcoming of the GPS technology and machine visual technical in the variable machinery application, and the development status of the variable mechanical based on machine vision's key techniques have been explained in detail, such as light source, capturing dynamic image (CCD camera and image frame grabber), image processing , fast accurate actuator, and so on.

1引言精细农业生产技术是现代农业工程技术的重要标志之一，是利用现代信息技术、机电一体化技术对传统农业机械进行改造的主要方向。研究和开发以"空间差异"准确定位定量操作的"变量"农业机械是今后农业机械化研究的重点方向，其相关技术和设备的研究已成为国际上正在研究的重点课题。

No city in the United States better exemplifies the values and sophisticated craft of our profession than our capital. Major Pierre Charles L'Enfant, a French-born aid to President George Washington, planned this city in the late 18th century.

首都华盛顿是全美展示景观设计职业价值和精细工艺实践的最佳城市。18世纪晚期，有位名叫Pierre Charles L'Enfant的法裔市长规划了这个城市，该市长是乔治华盛顿的助理。

Meanwhile the nonhydrostatic and high-resolution character and physical processes contained in the cloud model can be made use of. In this way some of the difficulties met in the fully description can be overcome. So we can investigate the effect of surface friction on the frontogenesis in the boundary layer in high-resolution nonhydrostatic model. The structure of the front obtained through this approach is consistent with the observation.

在高分辨率情况下研究了地面摩擦对边界层内锋生的作用，从而得出比较精细的、与实际观测相一致的类似重力流的边界层内锋面结构特征，说明了地面摩擦对锋生和锋面结构的重要影响，这是以往数值模拟还没有得到的结果。

The carved gable, the pointed roof, the turrets suspended at the angles of the walls;the stone pyramids of the eleventh century, the slate obelisks of the fifteenth; the round, bare tower of the ''.

石砌的山墙、尖角的屋顶、墙拐角悬空的小塔、石垒的金字塔、十五世纪石板方碑、城堡光秃秃的圆形主塔、教堂精细装饰的方形塔，大的，小的，粗大厚重的，小巧玲珑的，纷至沓来，叫人目不暇接。

The DNA fingerprints of 4 biotypes of GM population from 7 locations were analyses by AFLP.Base on the fine mapping of resistance gene Gm6 against all 4 Chinese GM biotypes by RAPD and SSR methods respectively,the STS markers and SSR markers linked to gene Gm6 were used for breeding through marker assisted selection.Some new resistant germplasm with Gm6 gene were created.And 6 cultivars and 6 lines of two-line hybrid rice and 1 line of three-line hybrid rice against GM were bred and extended to the farmer.The technique system of MAS for resistant varieties against Asian rice gall midge was set up at Guangdong province of China.

用AFLP方法对从中国广东省7个地点采集的4个生物型的DAN指纹进行分析；在对用RAPD和SSR技术分别对抗中国4个稻瘿蚊生物型的基因Gm6精细定位基础上，用与Gm6紧密连锁的STS和SSR标记开展分子标记辅助育种，创造了一批抗稻瘿蚊的新种质，包括育成了6个栽培稻和6个二系杂交稻和1个三系杂交稻并在农户试种，在中国广东成功地建立了分子标记辅助选育抗稻瘿蚊品种的技术体系。

Besides the pollution item, we absorb all kinds of industry items which are large-scale, full of science and technology and strong developing power, such as fine chemistry, ocean chemistry, salty chemistry, new pattern material, biology engineer, stainless steel, slap-up porcelain, electron parts, textile, garniture.

除限制污染性项目外，各类工业项目都可以引进，突出引进规模大、科技含量高、具有较强的经济发展后劲和带动作用的项目（精细化工、海洋化工、盐化工、新型材料、医药、生物工程、不锈钢精铸、高档贝瓷、电子原件、纺织、服装）。

Plunder melds and run with this jewel!

掠夺melds和运行与此宝石！

My dream is to be a crazy growing tree and extend at the edge between the city and the forest.

此刻，也许正是在通往天国的路上，我体验着这白色的晕旋。
