No.2 turbo generator in Hanchuan Power Plant was shut down due to violent vibration.The causes for the unplanned outage were diagnosed as follows:the sliding layer fault of rotor winding leaded to hindering winding expansion and affecting the uniformity of ventilation resulted in hot bending of generator's rotor.The vibration was improved through hot balancing before the overhaul,ensuring the safe operation of steam turbine generator.During the overhaul,all the spacing strips beneath the wedges were replaced,and the hot bending was eliminated,so as to make the shaft vibration reach excellent level under all operating conditions.

汉川电厂2号发电机因剧烈振动停产,经诊断振动是由转子线圈滑动层的故障引起,这种故障使线圈膨胀受阻,并影响通风的均匀性,结果引起发电机转子的热弯曲。大修前通过热平衡改善振动,保证了机组安全运行。大修期间更换全部楔下垫条,消除了热弯曲,使各种工况下轴振动达到优良水平。

On a fertile land, a winter wheat cultivar with medium spike size Tat 876161 was chosen and planted in sowing patterns in which 20cm narrow row space paired with 30cm, 40cm, 70cm or 100cm wide row space respectively were designed, and thus, forming four different strip patterns of 50(20+30)cm, 60(20+40)cm, 90 (20+70)cm and 120(20+100)cm, taking the conventional 20cm equal row spacing (strip width pattern of 20 + 20) pattern as control. Five different seed rates were employed, ie, one metre...

On a fertile land, a winter wheat cultivar with medium spike size Tat 876161 was chosen and planted in sowing patterns in which 20cm narrow row space paired with 30cm, 40cm, 70cm or 100cm wide row space respectively were designed, and thus, forming four different strip patterns of 50(20+30)cm, 60(20+40)cm, 90 (20+70)cm and 120(20+100)cm, taking the conventional 20cm equal row spacing (strip width pattern of 20 + 20) pattern as control. Five different seed rates were employed, ie, one metre single row had 15, 30, 45, 60 or 75 seedlings respectively. The main results are as follows: (1)The single row yield(y) increases in the way y=a/x + b as the wide row space(x) changes from narrow to wide. (2) The yield of strip type (20+ 20) (CK), (20+ 30),and (20+40) decreases markedly as the seed rate change from low to high,while strip type (20+ 70) and (20+100) decreases slightly. Each strip type acquires peak yield throuth employing small seed rate(15 seedlings/m). (3)As the wide row space (x) changes from narrow to wide, yield per 666. 7m~2 (y) changes in the way y = axe~bx. The calculated wide row space of peak yield of 15, 30, 45, 60 and 75 seedlings/m is 39. 55,41. 11, 44. 10, 43. 93 and 44. 93cm respectively. Use the average of the five seed rates, the formula is y = 36. 60684xe~-2.353119×10~-2x, r = 0. 9946189~**, and the calculated peak yield wide row space is 42. 50cm. (4) (20+40) pattern (paired row sowing with 20cm narrow row space and 40cm wide row space) can best coordinate the relations between spike number, grain number per spike and grain weight,thus it has the peak yield. Moreover,40cm wide row space is suit able for intercropping winter or spring vegetable crops and for relay cropping corn,peanut, cotton,soybean or ginger etc.

在高产田条件下,选用了中穗型冬小麦品种泰876161,设计小麦大小行播种,小行距 20cm,大行距分别为30、40、70及100cm,形成了50(20+30)、60(20+40)、90(20+70)及120 (20+100)cm 4种带型模式,以常规 20cm等行距(20+20)模式栽培作对照。试验又设置了 5个 播种密度,即1m单行基本苗数分别为15、30、45、60及75。研究了小麦带型-群体-产量的相关规 律。主要结果是:(1)行产量(y)随宽行距(x)加宽而提高,增长规律拟合为y=a/x+b的函数 形式。(2)随播种密度加大,(20+20)、(20+30)及(20+40)模式行产量明显下降,而(20十70)及 (20+100)模式则下降不甚明显。各带型均在精量播种下(15苗/m)获得高产。(3)随宽行距(x) 加宽,产量(y)拟合为y=axe~bx的函数变化形式,15、30、45、60及75苗/m拟合的最高产量的宽 行距分别为39.55、41.11、44.10、43.93及44.93cm。5个密度平均拟合方程为y= 36.60684xe~-2.353119×10~-2x,r=-0.9946189~**...
