G. cutting roots from 4 surface on the position 20cm away from the stem base nor cutting roots too near from stem base e.

若断根数量太多（如距茎20厘米处4面断根），或断根位置距茎基部太近（距茎基部10厘米处1面或4面断根），都不利于叶片含钾量提高

In partial celestial sphere celestial Star-Identification, the initial attitude is known. With a certain angular and distance tolerance, the separation angle of the observed stars and that of the catalog stars are matched, then, the star triangles are composed in real time. According to the rules of vector rotation, the inconsistent rotation star triangles are removed. After that, put the star triangles with public vertex into star polygon.

在局部天球星图识别方面，因为已知初始姿态，在一定角距容差和星对容差范围内和已知视轴附近的导航星角距表进行角距匹配，实时组成星三角，根据矢量法则剔除旋转方向不一致的星三角后，再把拥有公共顶点的星三角组合成星多边形。

Kuehl's triangle Star-Identification, some improvement had made. With a certain angular and distance tolerance, the separation angle of the observed stars and that of the catalog stars are matched, then, the star triangles are composed in real time. According to the rules of vector rotation, the inconsistent rotation star triangles are removed. After that, put the star triangles with public vertex into star polygon.

Kuehl的三角形星图识别的基础上进行了改进，即在一定角距容差和星对容差范围内和整个导航星角距表进行角距匹配，实时组成星三角，根据矢量法则剔除旋转方向不一致的星三角，把拥有公共顶点的星三角组合成星多边形。

The text obtains some data that caving span of immediate roof is 30m, caving span of main roof at first weighting is 42m and caving span of main roof at periodic weighting is 14m. Mining influence range is determined about 40m through numerical modeling, namely about three advance pillars were in the range of mining influence.

利用数值模拟得出煤柱采场直接顶的垮落步距为30m，老顶的初次来压步距为42m，老顶的周期来压步距为14m；通过模拟超前支承压力，确定了采动影响范围约为40m，即采场超前的三个煤柱都在影响之内。

The root hair morphology of cv. RM109 was observed and compared. The results indicated that in the distance of 1 cm to the apical of seed root, the number of root hair of RM109 was 19% of cv. Oochikara, and the root diameters were not different from cv. Oochikara; in the distance of 8 cm, the number of root hair and the root diameters of RM109 were 45% and 79% of cv. Oochikara, in the distance of 3 cm, the length of the longest root hair was 33% of cv. Oochikara; but the length from the apical of the seed root to root hair initiation was not different.

根毛观察比较显示，距种子根根端1 cm处的RM109根毛数是&大力&品种的19%，差异极显著，根直径与&大力&品种差异不显著；距根端8 cm处的RM109根毛数和根直径分别是&大力&品种的45%和79%，二者差异极显著；距根端3 cm处，RM109最大根毛长是&大力&品种的33%，差异极显著；RM109种子根根端到根毛发生区的长度，与&大力&品种的差异不显著。

The correlated distances of bottom soil watercontent at different times were bigger than those of surface soil. Soil salt content did not have thisphenomena. The possible reason was that the bottom soil salt content was mainly affected bygroundwater.

两个时期土壤底层含水量的自相关距都要大于表层的自相关距，而盐分的空间自相关距没有表现出这种现象，这可能与底层盐分受到地下水作用的影响比较大有关。

Results:The anterior bundle of the UCL starts from anterior inferior part of the medial condyle,and ends on the sublimis tubercle in front of the coronoid process of ulna,locating in the deep layer of the flexor carpal ulnar muscle.The distance between ulnar nerve and UCL is (0.9±0.1)cm in the center of cubital tunnel,and (0.6±0.3)cm in the distal foramen of cubital tunnel.The distance from the point of ulnar nerve entering the flexor carpi ulnar muscle to the medial epicondyle is (3.7±0.8)cm.The distance between the closest branch innervated flexor muscle of the median nerve and the approach is (1.6±0.5)cm at the level of medial epicondyle,and (0.9±0.4)cm at the level of ulnar tubercle.

结果：UCL前束起于肱骨内侧髁的前下方，止于尺骨冠突内侧的小结节，UCL前束位于尺侧腕屈肌肱头、尺头之间的深层；尺神经在肘管中部与尺侧副韧带前束的平均距离为(0.9±0.1)cm，在肘管的远侧出口，距尺侧副韧带的尺骨止点(0.6±0.3)cm；尺神经至尺侧腕屈肌尺头肌支的入肌点距肱骨内侧髁的距离为(3.7±0.8)cm；正中神经最靠近切口的分支距切口的距离，在肱骨内侧髁和尺骨结节水平分别为(1.6±0.5)cm和(0.9±0.4)cm。
