查询词典 trouble shoot

We studied the optimum medium and hormone combination of callus induction from cotyledons, subculture of callus, shoot regeneration from callus, shoot-extension induction, root induction and identified the chromosome number of the plantlet. The results showed that: MS+2,4-D 2.0mg/L+KT 0.5mg/L, MS＋2,4-D 2.5mg/L＋KT 0.5mg/L, MS+2,4-D 0+KT 1.0mg/L, MS+KT 0.5 mg/L and basal MS medium. One plantlet among twenty two was determined as a tetraploidy based on the plant morphology, observation of the leaf stoma and chromosome number of the root, other two plantlets represented morphological variation.

But shooting the sun is tricky. On a clear day, the sun is so bright that your camera's meter will tend to underexpose everything else in the frame. Shoot in manual mode, or take a reading without the sun in frame, depressing the shutter button halfway to hold the exposure, then reframe before you shoot. If you're shooting film, bracket a lot to make sure of getting the exposure you want.

把太阳放在构图中以表达沙漠中的高温和荒芜，但拍摄太阳比较麻烦，晴空下的阳光影响相机的感光计，以至于构图中其它部分曝光不足，为避免这种情况，要启用相机的手动模式，或者是将太阳从构图中排除后，半按下快门固定曝光值，然后重新选择有太阳的构图，将快门按到底。

Think about including the sun in your photograph—it's one sure way to say hot and harsh. But shooting the sun is tricky.

The results showed that:Under NaCl stress,the reductions in the shoot and root dry weight, leaf area,stem diameter of grafted plant were lower than those of ungrafted plants.The Na~+ content,Na~+/K~+ ratio,Na~+/Ca~(2+) ratio in the leaf and scion stem of grafted plants were lower whereas those of in the rootstock stem ad root were higher than in ungrafted plants. The K~+ contents,soluble sugar contents,shoot water contents,SOD,POD,CAT,APX activity,the stability of AsA/DHA,Photosynthetic rate,transpiration rate and stomatal conductance were higher,whereas the MDA contents in the leaf of grafted plants were lower than that in ungrafted plants.The reductions in leaf area and stem diameter of grafted \'Jinchun No.2\' plants were more severe than those of grafted \'Zaoduojia\' ones.

结果表明，盐胁迫下，嫁接苗地上部和根干重、叶面积、茎粗降低的程度显著低于自根苗；嫁接苗叶片和接穗茎中Na~+含量和Na~+/K~+、Na~+/Ca~(2+)比值显著低于自根苗，而砧木茎和根中的Na~+含量和Na~+/K~+、Na~+/Ca~(2+)比值显著高于自根苗；嫁接苗叶片中K~+含量、可溶性糖含量、地上部含水量、SOD、POD、CAT、APX活性、AsA/DHA的稳定性、光合速率、蒸腾速率、气孔导度显著高于自根苗，MDA含量显著低于自根苗。

The results showed that:The reductions in the shoot and root dry weights, leaf area,stern diameter of grafted plants were lower than those of ungrafted plants under the same NaCl stress.Na~+,MDA,H_2O_2 contents,O_2~- producing rate,Na~+/K~+ ratio, Na~+/Ca~(2+) ratio were lower,whereas K~+,solube sugar,shoot water content,SOD,POD, CAT,APX activity,the stability of AsA/DHA,Photosynthetic rate,transpiration rate and stomatal conductance in the leaf of grafted plants were higher than those of ungrafted plants at the same NaCl stress.Intercellular CO_2 concentration of grafted plants decreased whereas that of ungrafted plants increased significantly under salt stress.

结果表明，盐胁迫下，嫁接苗地上部和根干重、叶面积、茎粗受抑制的程度显著低于自根苗；嫁接苗叶片中Na~+、MDA、H_2O_2含量、超氧阴离子产生速率、Na~+/K~+和Na~+/Ca~(2+)比值显著低于自根苗，而叶片中K~+含量、可溶性糖含量、地上部含水量、SOD、POD、CAT、APX活性、AsA/DHA的稳定性、光合速率、蒸腾速率、气孔导度显著高于自根苗；嫁接苗的胞间CO_2浓度显著下降，自根苗的则显著上升。

Copper concentrations and uptake were greater at the early growth stage than those at the later growth stage, and at harvest the shoot Cu concentration was lower than 100mg kg〓 for both Elsholtzia plants. At harvest, shoot removal of total Cu from soil was more than 0.5kg ha〓 for one season.

The fourth chapter talks about the weft carrier, in this part, we mostly introduce the big gripper shuttle in the comparative way and not only analyze the structure but also analyze the stress of the fatigable parts. In the fifth chapter, the shuttle box is our research emphasis, we start with the design principle and analyze its structure and the logic of the action of the parts. The sixth chapter discusses the shoot mechanism, builds its theory model and analyzes its law of motion from the view of kinematics and kinetics during the wefting. And then, we can consider the hydraulically shoot mechanism and comprehend its principle and some special parts. Subsequently, the content is about the flying of a shuttle, because the course of the flying of a shuttle is very complex, it is necessary to study the shuttle according to mechanics and to analyze its course of motion and its change of speed from the view of energy.

第五章谈的是梭箱，这部分从梭箱的设计原理入手，从结构的角度对梭箱进行分析，考虑到梭箱上各执行件间的动作存在一定的逻辑关系，还对执行件动作时间与控制作出论述，从中可以看出重型宽幅织机所独有的特性；第六章论述投梭机构，先构造出投梭机＿重型宽幅织机引纬机构与梭箱的设计＿构的弹性理论模型，从动力学的角度剖析投梭规律，随后分析液压式投梭的工作原－－理和一些特型元器件；第七章论述梭子的飞行运动，考虑到梭子飞行运动的复杂性，我们把梭子飞行运动划分为三个阶段，然后分阶段介绍其运动规律，在对梭子进行＿运动分析的同时还详细分析它的受力情况，在这一章的最后，我们对影响梭子飞行＿的因素也作出了讨论；顺沿这一过程，即是第八章对制梭机构的论述，在这一部分，、主要研究制梭过程与制梭力的情况，同梭子飞行过程一样，制梭过程也分为三个阶段，就每个阶段而言，我们都对其进行受力与运动方面分析，同时也就一些容易出现的问题作出讨论；最后两章是对纬纱交接机构和纬纱的退绕与张力控制作出讨＿论，鉴于这两部分不存在复杂的动力学方面的问题，论述重点便放在结构与原理的分析上面，包括分解纬纱交接机构，解析其动作过程，介绍储纬与纬纱张力的一些情况。
