查询词典 double root

Wetland plants have a series of physiological and anatomical characteristics to adapt flooding habitat, e.g., their root aerenchyma and oxygen-penetrating capability can make the rhizospheric micro-environment be under oxidation condition, resulting in the formation of Fe/Mn plaques on root surface.

湿地植物具有一系列生理和结构上适应浸水环境的特征，如根系的通气组织和渗氧能力，这使得植物根际微环境处于氧化状态，这样土壤中的铁和锰会在植物根表被氧化而形成红棕色的铁锰氧化物胶膜。

32P isotope tracing technique was used in this study,and the results indicated that phosphorus stored or pre-existed in roots would be remobilized in maize under phosphorus deficiency from root cortical cells with lysis to shoot mostly rather than root apex during aerenchyma formation.

Kraus等的试验表明玉米根系从土壤中吸收的32P可在根皮层内保留15 d，之后逐渐减少[2]。这意味着与叶片的情形相似，根内也进行着磷的活化和再运转。当植物处于磷胁迫下时，根系吸收的磷素远不能满足植物各器官生长发

Among her serial works named Hero,one depicts like this:on a desolate ground only with root remained,a plane which was supposed to enter into the air lane stayed on a root,a self-assured young pioneer with a hat receiving alien messages holds a spade but could not find a green land to irrigate,only leaving the red scarf fluttering…..

在她的命名为hero的系列作品里边，有一件作品是这样的：在一片只剩下树根的荒漠的土地上，一架本该进入航道的飞机却在某个树根上搁浅，一位踌躇满志头戴"接收外星人信号"帽子的"少先队员"拿住一把铁锹却找不到可以灌溉的绿地。

This paper discusses some algorithm of division and square root. Inmy design, I use improved Newton algorithm for square root and Goldschmidt al-gorithm for division.

Similarly, the alveolus is attached to the root by the periodontal ligament and is in turn pulled along by the movement of the root.

同样，肺泡附在根的牙周膜，并反过来又退出了沿线的运动的根源。

Longitudinal root sections of the wild type and the gls mutant cultured in nutrient solution for 4 days showed that biosynthesis and distribution of amyloplast in the columella cells of gls were normal as compared with the wild type, suggesting that root gravitropism loss in gls mutant is not caused by the defect in amyloplast sedimentation, but possibly by the disturbance of auxin transport and distributation.

4天龄的根系纵切片结果显示：突变体gls根尖结构完整，根尖柱细胞内淀粉粒的生成和分布正常，表明gls突变体根系向地性的缺失不是由于淀粉体的原因，而可能通过影响生长素运输和分布造成。

In low age larva is filled period the effect of prevention and cure to garlic root maggot undertakes different drug experiment and be investigated, the result makes clear: 27 years garlic root maggot produces 3 generation in Jiangsu, generation of live through the winter is imaginal in March the last ten-day of a month fills hair; the middle ten days of a month on April fills generation larva hair, the middle ten days of a month saw in May aurelian, the last ten-day of a month was; of fastigium of generation imago ascend to heaven and become immortal in May the 2nd generation is larval the first ten days of a month was filled to the middle ten days of a month in June hair, the last ten-day of a month came in June in September the last ten-day of a month with aurelian more summer, 2 generation are imaginal at; of the ascend to heaven and become immortal at the beginning of October coming by September the 3rd acting larval fastigium is on October the middle ten days of a month, the first ten days of a month is larval in November in succession pupate live through the winter, immediately following in time year of spring (the middle ten days of a month on April) begin emergence.

在低龄幼虫盛期就不同药剂对大蒜根蛆的防治效果进行试验和调查，结果表明：2007年大蒜根蛆在江苏发生3代，越冬代成虫于3月下旬盛发；第一代幼虫4月上中旬盛发，5月中旬见蛹，5月下旬为一代成虫羽化高峰期；第二代幼虫6月上旬至中旬盛发，6月下旬至9月下旬以蛹越夏，二代成虫于9月底至10月初羽化；第三代幼虫高峰期在10月上中旬，11月上旬幼虫陆续化蛹越冬，翌年春季(4月上中旬)开始羽化。

The traditional Givens rotation algorithm involves root computation that needs more hardware resources, a Givens rotation algorithm without root and division computation is presented. And, combined with special structure of input signal matrix, a interference suppression algorithm with low computation is proposed. The narrowband interferences are modeled as autoregressive process and digital signal.

传统Givens旋转算法涉及平方根运算，要消耗较多硬件资源或需要多次循环来实现，为此，提出一种无平方根与除法运算的Givens旋转算法，并结合信号输入矩阵的特殊结构，给出一种低复杂度的干扰抑制算法，将窄带干扰建模为自回归过程以及数字窄带信号。
