Plant height, leafstalk length, leaf length, leaf width and leaf thickness of water hyacinth did not vary significantly at the range of pH 3.5 to 9.0, while root length, stolon length and root vigor declined obviously with the increasing pH.

随营养液pH值升高，水葫芦的相对生长率从6.12倍降到3.08倍。pH值在3.5—9.0之间，水葫芦株高，叶柄长度，叶片的长度、宽度和厚度在不同酸度条件下无显著差异，根长、茎长和根系活力随pH升高明显下降。

The captain has he has both sons and daughters, so we have to choose from 3 and 2 .If we choose 3, then the age of captain should be choosen from 21 11, and 12(8 is left for the boat length).

思路大概是这样的，孩子的数目应该是一位数的，船长的年龄是两位数，所以船的长度也是两位数，那么可能的船的长度的十位数就只能是8。

The left to optimal length, Tmax increases as initial length increases.

达到最适初长度以前，最大张力随初长度的增加而增加。

There were no significant differences (P＜0.05) in length between the left and the right in one worker′s hypopharyngeal gland.

测定19只工蜂头部咽下腺的两条腺体长度和重量，经生统t检验，发现同一工蜂的左、右两条咽下腺长度、重量差异都不显著（P＜0.05）。

Cut six lengths of seam binding which are long enough to span the entire arc length of the canopy, with a little extra length that may be trimmed later.

削减6长度煤层具有约束力，这是足够长的跨度，整个弧长的天篷，一点点额外的长度可能削减后。

Result:①The actual length of upper and lower normal esophageal tissue after having been made into pathological giant sections in 52 patients, were 30±14% and 44±19% of that measured in the operation.

结果：①52例食管癌病理标本制成病理大切片后，癌上食管平均收缩为术中长度的30±14%；癌下食管平均收缩为术中长度的44±19%。

Sometimes the context of the mode would require a group of only two semibreves, however, these two semibreves would always be one of normal length and one of double length, thereby taking the same space of time, and thus preserving the perfect of the tempus. This ternary division held for all note values.

有时候根据实际情况的需要一组仅有2个全音符，但是这种2个全音符的模式也总是标准长度中的一种并且是这个长度的两倍，因此有着相同的时长，其结果是即使保留节拍的一部分，这种三分法包含了所有的音符价值。

Based on the analysis of current situation of urban traffic signal control, a method of single intersection signal control was presented based on fuzzy neural network control. Density of vehicle flow of current and next phase was determined by detecting the queue length of the current and next phase, so that it was further determined whether the phase should be changed or not.

在分析城市交通信号控制研究现状的基础上，提出一种基于神经网络模糊控制的单路口交通信号灯控制方法，通过检测当前相位的排队长度和下一相位的排队长度得出当前相位以及下一相位的车流密度，进而判断是否进行相位变换。

Only if the component vectors are on a straight line will the length of the vector for the sum be equal to the sum of the lengths of these components or to their difference.

只有当几个分矢量在一直线上，那么表示其和的矢量长度才会等于这些分量的长度和或它们的差。

Based on the traits of the aspherical lens, the sunlight was focused on a very small spot, and then it was transferred into a plastic fiber by an aspherical lens and a selfoc lens. A formula for calculating the optimal length of selfoc lens is presented. The optimal assembly of the aspherical lens and selfoc lens was implemented by the aid of this formula. Therefore, sunlight is coupled into a plastic fiber efficiently.

根据非球面透镜垂轴球差小的特点把太阳光会聚到很小的光点，再利用长度约为1/4节距的自聚焦透镜改变光线的数值孔径使其满足光纤的数值孔径，通过一个计算公式来计算最佳的自聚焦透镜长度，实现非球面透镜和自聚焦透镜的最佳组合，把太阳光以较高的耦合效率耦合进塑料光纤。
