RESULTS At1week after the onset of diabetes,the implicit time of dark-adapted ERG's a and b-waves and oscil-latory potentials'O2 -wave in rats was delayed significantly and continued to delay with the duration of the disease.

结果 大鼠scot-ERG的a波和b波和OPs的O2 波的潜伏期，在1wk时［a波（27.2±1.9）ms，b波（72±6）ms，O2 波（38±4）ms］，与未打药时相比［a波（24.1±1.2）ms，b波（64.6±2.9）ms，O2 波（34.1±1.6）ms］，显著延长，2wk时潜伏期继续增加［a波（28.4±1.9）ms，b波（76±10）ms，O2 波（41±6）ms］，幅值一直没有显著改变。

However, if the trigonal control point and datum transformation model do not exist, the result of base station single point absolute location can be used as reference coordinate, the measured result of which can be geo_referenced to remote sensing image using some tiepoints on the basis of the first result above.

例如 ，在利用遥感影像分类时，需要在外业获取用于监督分类的训练样地或是分类结果精度检验样地的大地坐标信息；在进行稀有树种区域分布特征调查时，希望能在遥感影像上标识出每个树的具体位置；发现某河段发生污染时，很可能需要将它的精确位置以线或面的形式显示在其它矢量或栅格图层上。

The results showed that the sandy soil in layered soil profile can stimulate or obstacle the water movement as compared to the uniform loam column with 50cm depth of water table, this was mainly determined by the position of the sand layer.

结果表明，砂层对于水分的蒸发既有促进也有抑制作用，在地下水埋深为50 cm时，5 cm厚的底砂层可使水分的蒸发强度增加10%～20%；砂层距水位的距离大于5 cm时，砂层可抑制水分的蒸发，且当距离增加到35 cm左右，其抑制率可达70%～80%；当砂层距水位的距离继续增大时，水分的蒸发强度基本保持不变。

When entering the diaphragm pressure on the top of the control room to the atmosphere or water by the downstream area of low pressure, the role of the bottom plate in the valve and the pressure below the diaphragm on the pressure value is greater than the top, so the main valve disc to the fully open position; when entering the diaphragm pressure above the control room can not water the lower reaches of the atmosphere or area of low pressure, the role of the diaphragm on the top of the pressure value is greater than the pressure below the value, so will the main valve pressure valve set to fully closed position; when the diaphragm pressure above the value of the control room at the entrance of the middle pressure and outlet pressure, the main valve in the regulator valve on the disk, and its regulation depends on the location of the needle-catheter system and adjustable valve guide of the role of joint control.

当阀门进入隔膜上方控制室内的压力水被排到大气或下游低压区时，作用在阀盘底部和隔膜下方的压力值就大于上方的压力值，所以将主阀阀盘推到完全开启的位置；当进入隔膜上方控制室内的压力水不能排到大气或下游低压区时，作用在隔膜上方的压力值就大于下方的压力值，所以就会把主阀阀盘压到完全关闭的位置；当隔膜上方控制室内的压力值处于入口压力与出口压力中间时，主阀阀盘就处于调节状态，其调节位置取决于导管系统中的针阀和可调导阀的联合控制作用。

Firstly, this paper analyzes the transmission style of diving machine in detail and selects hydrostatic transmission as transmission manner of Heavy Engineering Transporter. Then we analyze the principle of hydrostatic transmission, control style of hydraulic components and the basic driving theory of transporter and pay attention to solve the problems of driving speed-regulation control when transporter runs on different road surface and differential speed control ensured every wheels pure roll when transporter is in swerving.

接着分析了静液压传动的液压原理、静液压传动液压元件的控制方式和汽车行驶理论基础，主要解决了以下控制问题：(1)车辆在不同工况下行驶时，选择不同速度的整车调速控制；(2)车辆转弯时，为确保车轮实现纯滚动，而使各驱动轮按设定规律运动的差速控制；(3)车辆从一坡度过度到另外一坡度时，使每个驱动桥实现同步的桥间差速控制。

"Dog Flea" is a ring game song in which kids hold hands and circle around one person in the middle. That person tries to break out of the circle on the line "dog flea is a bitin' me," and the group responds,"don't keer caint git outa here." When someone finally does break out of the circle, everyone chases him or her until that person is caught.

狗身上的跳蚤」是一首围圈歌唱游戏，游戏进行时，孩子们围成一圈站立，手牵手把一人围在圈中；当唱到「我被跳蚤咬了一下」( dog flea is a bitin' me )时，站在圈中的必须试着破圈而出，而在同时，围成圆圈的孩子们则回以「你不能从我这儿出去」( don't keer caint git outa here )；最后，当有人破圈而出时，所有的人会开始追逐那个人，直到那个人被抓住为止。
