有效数

Our test showed that defoliation to theextent of 1/4 was most effective.

对夏播苦瓜采取摘叶处理是一种有效的植株调整方式，我们的试验结果表明株洲长白苦瓜摘叶1/4是最有效的方法，使植株的雌花数和♀/♂比值都显著提高，单株实收果数和总果量也都提高；但摘叶过多，如摘叶1/3和1/2，反而使雌花数减少，产量下降。

The exact effective nuclear charge numbers have been defined andcalculated with the mean radius of the initial orbital of the active electron toconsider the combined -effects of relativity and screening in an actualtranstition calculation . The electron impact ionisation cross sections and thecorresponding ionisation rate coefficients of Li like ions 〓、〓、〓、〓and〓 have been calculated by using our calculated effective nuclearcharge numbers.

我们考虑并修正了原始理论中对屏蔽常数物理意义的不正确定义和算法，更精确考虑了其它电子对被电离电子的屏蔽效应以及相对论收缩对有效核电荷数的影响，得到了更可靠的有效核电荷数，并给出了更好的电离截面结果。

In computing , most significant bit is the bit position in a binary number having the greatest value. The msb is sometimes referred to as the left-most bit , due to the convention in positional notation of writing more significant digits further to the left.

在计算机运算中，最高有效位，是指在一个二进制数中具有最大值的那一个二进制位。msb有时也被称为"最左边的位"，这是因为在权位记数法中习惯上将较大的有效数字顺序的写在左边。

Using quadratic rotational regression combination design to study the influence on yield and economic characters in different fertilizer and density of the rape, the result showed that the influence of density and fertilizer on yield and active silique per plant were significant but the quantity and weight of seed, while the influence of density on active silique per plant was higher than that of fertilizer but on yield was contrary.

结果表明，在本试验范围内，施肥量和密度对油菜单株有效角果数和产量均有显著的影响，对单株有效角果数的影响是密度大于施肥量，而对产量的影响则是施肥量大于密度；单株有效角果数的最佳组合为施肥量以纯氮227.0kg/hm2、密度9.4万株/hm2，产量的最佳组合为施肥量以纯氮235.7kg/hm2、密度10.6万株/hm2；当控制施肥量、密度分别为214.4—256.9kg/hm2、10.1—11.1万株/hm2时，油菜产量可达3000kg/hm2以上。

Control layer and parameter layer represent the available number of rows and the concrete value of the available rows of separation matrix respectively. Non-Gaussian was used to measure the independence of the stochastic signals. The kurtosis was maximized/minimized by searching a linear combination of observation signals, and then the independent variables were separated.

用控制层、参数层分别表示分离阵有效行数和有效行数的具体数值，将非高斯性作为随机信号相互独立的度量，通过寻求观测信号的一个线性组合，使其峭度最大化或最小化来分离独立分量。

Soil fertility and elucidative density are important factors affecting biological properties of field mint, such as total leaves of main stem, quantity of stem, total leaves of small stem, quantity of efficacious leaves among these properties, total leaves of small stem relieved more influence, and the degree of influence can be impressed by the ration of total leaves of small stem to main stem.

不同施肥水平与种植密度是影响薄荷生物学性状，即单株主茎叶片数、分枝数、分枝叶片数及有效叶片数的重要因素，其中分枝叶片数影响较大，可用单株分枝叶片数与主茎叶片数之间的比值反映出影响程度大小。

Range of grey correlation degree from high to low was plant height, effective pod numbers, seeds per legumen, 1000-seeds weight and effective branches.

不同海拔下各经济性状与产量关联度的变幅由大到小依次为：植株高度、有效角果数、每角粒数、千粒重和有效分枝。

Along with the increase of density, the highest tillering periods of the 2 varieties advanced.

每穗实粒数对P1的产量影响最大，其次是有效穗数；增加有效穗数能显著增加P2的产量。

Wheat physiological char acte rs show two stages by the dividing line of anthesis.In prophase,it mainly forms tillerings,differentiates the floscules and small heads,forms the base of heads number and grains number.In anaphase,it mainly accumulates effectively dry substance ,makes certain the grains number and grains weight ,so we can confirm the t hree yield factors,that is,heads number,grains number and grain weight.

在小麦生理性状的表现上以扬花期为分水岭分2个阶段，前期主要形成分蘖，分化小花、小穗，决定产量构成的亩穗数和穗粒数；后期表现干物质的有效积累，确定粒数、粒重，从而构成产量的三大因素：亩穗数、穗粒数和粒重。

The result showed that branches per plant, pods per branch, pods of main stem, pods per plant, seed weight per plant, seed number per plant and plot yield could be increased with the treatment of 270kg of phosphorus application rate per hectare.

结果表明，每公顷施270kg磷酸二铵能有效地增加分枝数、分枝荚数、主茎荚数、单株总荚数、单株粒重、单株粒数和小区产量。

With Death guitarist Schuldiner adopting vocal duties, the band made a major impact on the scene.

随着死亡的吉他手Schuldiner接受主唱的职务，乐队在现实中树立了重要的影响。

But he could still end up breakfasting on Swiss-government issue muesli because all six are accused of nicking around 45 million pounds they should have paid to FIFA.

不过他最后仍有可能沦为瑞士政府&议事餐桌&上的一道早餐，因为这所有六个人都被指控把本应支付给国际足联的大约4500万英镑骗了个精光。
