The yellow boards play an important role in prevention and cure white fly in greenhouse because they can trap, stick and kill white fly. The test also shows that almost white fly often appear in the space where 5cm-15cm upper than the top of the plant. According to this result, the optimal hanging height of the yellow board should be at the place where 5cm-15cm upper than the top of the plant. The yellow boards should be set up as much as possible in this space to reach the best preventative effect.
同时使用黄板诱杀这一物理防治方法,也可有效减少温室内白粉虱数量,并且确定了植物顶端上方5~15cm处是白粉虱较活跃的区域,因此黄板应尽可能多的覆盖这一区域,以达到最好的防治效果。

Field moisture capacity is the key factor not only resulting in afforestation success or failure, but also that impacting on productivity of stand at hot-dry valley of Jinshajiang River. It was concluded by the investigation that: the contour trench (40 cm×40 cm), mixted with can increase the field moisture capacity, in accordance, the productivity of stand could bue improved in some degrees. But bearing the weight of soil capability, survival individual plant on unit area was about 525 plant/hm^2. Further-more, introduction of the grade 1 seedling in afforestation could improve survival rate, and facilitate the stand productivity.
土壤含水量是影响金沙江干热河谷造林成败的关键因子,同时也是影响林分生产力的限制性因子,通过试验得出:采用水平沟整地(40cm×40cm)、与多年生小灌木混交,可在一定程度上提高林地土壤含水量,从而使得造林保存率和林分生产能力均有提高,但是受其土壤承载能力的影响,单位面积的保存株数保持在525株/hm^2左右;此外,用Ⅰ级苗木造林,不但可以提高造林保存,对林分的后其生长也有促进作用。

Results indicated that, with cotton varieties succession, in the primary factor of yield constitution, the number of bolls per plant, lint index and lint percentage increased obviously, in which the number of lint percentage in modern varieties was 7.5%~19.9% higher than old varieties, along the lint index increased the seed index obviously drops with cotton variety change; boll weight and the number of bolls per plant displays opposite tendency, there was a declined trend in boll weight, from 5.9g in old varieties to 5.3g in modern varieties.

The results showed that the calorific values of the test plant species had no unified change pattern, which was possibly related to the partitioning ratio of calorific value in different plant organs and the timing when the reproductive period appeared. In general, spike had a higher calorific value than leaf and stem, and aquatic plants had obviously lower calorific value than mesophytes and wet mesophytes. Within a species, the change pattern of calorific value had certain relations to the phenophase, with approximately two lowest values and two highest values. Among the species, the differences in the calorific value were decided by the nature of the species themselves. Under the same habitat and climatic conditions, the species that contained more materials rich in energy could more easily accumulate calorific, and thus, more adaptable to grow under this environment.
结果表明:各物种的热值动态变化规律并不是统一的,这种变化可能与植物各器官热值的变化及生殖期出现的时间有关;各植物器官的热值普遍表现出穗的热值大于茎和叶;水生植物的热值明显小于中生性和湿中生性植物;种内热值变化随物候期变化有一定的规律,大约会出现2次低值、2次高值;种间热值差异是由于植物本身性质决定的,在相同生境和气候条件下,植物体中含能物质越多,就越易积聚热值,从而更适宜生长在此环境。

Based on these, an improving μ-synthesis is presented, with which the high-purity distillation is designed well. 2. The robust performance problem of MIMO plant is explained with the plant direction angle, which shows that the robust performance varies with different input uncertainties and the μ-synthesis should be applied correctly according to the uncertainty structure. 3. Condition number and bandwidth are the important items for robust performance design in MIMO system. The H〓 two-block problems can not deal with the robust performance design of MIMO system because of the condition number cancellation. A general μ-synthesis procedure for MIMO system with uncertainties is presented. 4. For the SISO system, the object function in robust performance is amplified by at most 〓 than that of H〓 two-block problems in value: So the robust performance of SISO system can be done with the H〓 two-block problems to avoid the complicated μ-synthesis procedure. 5. All the conclusions and methods presented in this paper are demonstrated by some typical design examples.
从而形成一种改进的μ综合方去,并对精馏塔病态对象进行了鲁棒性能设计,得到令人满意的结果;(2)利用对象的方向角解释了MIMO对象鲁棒性能设计出现问题的原因,并提出不同输入摄动形式下系统的鲁棒性能问题也并不相同,因此利用μ综合处理鲁棒性能设计时,应根据不同的摄动情况采用不同的结构进行设计:(3)条件数问题和带宽问题是MIMO系统鲁棒性能设计的两个主要问题,指出由于条件数对消的存在使得一般H〓两块问题无法处理MIMO系统的鲁棒性能设计,而μ综合方法则是处理MIMO系统鲁棒性能设计的有效方法,并给出了其处理MIMO系统鲁棒性能设计的一般性方法;(4)提出对于SISO系统H〓两块问题(S/T问题、S/KS问题)的设计指标函数与鲁棒性能设计的μ指标函数在数值上最大差〓倍,因此对于一般SISO系统的鲁棒性能设计可以简单地用一般的H〓的两块问题处理,而避免μ综合设计的复杂过程;(5)本文中提出的结论和算法都利用H〓/μ发展中的典型例子:Doyle-Stein问题,Safonov的战斗机模型,精馏塔对象等进行了设计验证。
