查询词典 stem

Therefore, the flow can be taken to change the method, the stem end of P1 into P2 in the stem end, which is high pressure, pressure a large valve is more effective.

因此，可采取改变流向的方法，将P1在阀杆端改为P2在阀杆端，这对压力高、压差大的阀是较有效的。

To this end, the stem design is very small, fillers also used the coefficient of friction PTFE packing, in order to reduce bad back, but it is sent to the small stem, is easy to bend, fillers life was short.

为此，阀杆设计得非常细小，填料又常用摩擦系数小的四氟填料，以便减少回差，但由此派出的问题是阀杆细，则易弯，填料寿命也短。

To this end, stem design very small, another commonly used filler of PTFE packing friction coefficient REDUCING VALVES in order to reduce backlash, but this problem is to send small stem, is easily bent, packing too short life.

为此，阀杆设计得非常细小，填料又常用摩擦系数小的四氟填料，以便减少回差，但由此派出的问题是阀杆细，则易弯，填料寿命也短。

To this end, stem design Multi-stage pumps very small, another commonly used filler of PTFE packing friction coefficient in order to reduce backlash, but this problem is to send small stem, is easily bent, packing too short life.

为此，阀杆设计得非常细小，填料又常用摩擦系数小的四氟填料，以便减少回差，但由此派出的问题是阀杆细，则易弯，填料寿命也短。

The measures of cultivation of disease-free seedling, reduction of wound of stem and twig, wound sterilization after peeling diseased patch of stem and twig, cutting down badly diseased twigs are effective control method.

通过采取栽培无病苗木、减少枝条和主干的伤口、削除枝条和主干的病斑和进行伤口的消毒、砍除重病枝等措施，可以有效地防治病害的发生。

The harvest, including harvest of branches, leaves, cutting stem or the whole plant in short-period and high-yield officinal plantation of C. fortunei should be performed in autumn and winter 3-4 years or 4-5 years after planting, of which the stem should be cut at height of 10 cm.

利用农田设施栽培和山地种植的三尖杉药用林，可分别于栽植后第3~4年和第4~6年秋冬季进行枝叶采收、截干采收和全株采收，截干采收时截干高度以10 cm最佳。

Comparison of different types of stem cutting in rooting induced and analysis the cDNA clones which may be associated with the occurrence of adventitious roots of P.euphratica,the model of ARF were initial establishment of exogenous IBA controlling endogenous IAA occurred threshold and equilibrium,that is,exogenous IBA receiving by receptor of stem cutting,and transfer into the cells,then turn into active IAA by the effects of the POD enzyme.

通过对胡杨3个不定根发生调控培养体系的比较和与胡杨不定根发生可能相关的差异基因的克隆分析，初步建立IBA调控胡杨不定根发生的内源IAA阈值和激素间平衡的模型，即外源IBA通过插穗受体接收，转入细胞内并在POD酶作用下转化成具有活性的IAA，当IAA的水甲在促根的阈值内并保持相对平稳时，则有利于生根；当IAA的浓度增高超过阈值且不稳定时，则抑制不定根的发生。

G. cutting roots from 4 surface on the position 20cm away from the stem base nor cutting roots too near from stem base e.

若断根数量太多（如距茎20厘米处4面断根），或断根位置距茎基部太近（距茎基部10厘米处1面或4面断根），都不利于叶片含钾量提高

Adult stem cells can break away restricted lineage and be trans-differentiated into other mature cells, this phenomenon is referred to as plasticity which is the base of clinical application of adult stem cells and has a promising future.

这些干细胞可以打破胚层界限，横向分化为其他组织的成熟细胞，这种性质称为干细胞的可塑性，是成体干细胞应用于临床的理论基础，具有广阔的临床应用前景。

And the lesion number of severest diseased stem is over 100, the percentage of disease in Brown Spot is around 60%. From the result of fungicide test, we know the Difolatan, Benlate and Orthocide are the more effective for controlling Stem Blight, but the percentage of prevention don't reach the perfect effect. The effect of other fungicides is not good. So we must continue to work to search for safe, and ideal fungicides as the index of prevention.

由药剂试验结果，以Difolatan（预防率：100p.p.m为80.95%，200p.p.m为83.33%），Benlate（预防率：100p.p.m为85.71%，200p.p.m为92.85%），Orthocide（预防率：100p.p.m为71.42%，200p.p.m为73.80%），三种药剂对茎枯病之防治效果最佳，但预防率未达百分之百，其他药剂之防治效果不佳，故仍需进一步寻求安全、有效之防治药剂，以供今后笋农防治茎枯病之依据。
