The results show that biomass owns higher NO removal efficiency than pulverized coal. NO removal efficiency of three kinds of fuels increases by different extent through the increase of reburn fuel fraction and the decrease of the excess air ratio. NO removal efficiency of corn straw is the most efficient; rice husk is medium, pulverized bituminous coal is the lowest. Within the certain reburn resident time (650 ms), NO removal efficiency increases quickly with the resident time.

Compared of the efficiency of treating heavy metals in FGD wastewater with NaOH, Ca_2 and Mg_2. It indicated that NaOH was much efficient for precipitated waste water; Ca_2 was much efficient for unprecipitated waste water, the removal efficiency reached 98.4%. With the increasing of the main ion of Ca~2+, Cl~- in FGD wastewater, the efficiency decreased. It decreased 60% for the removing of Mn and 10% for Zn, Cd and Ni. The rectification coefficient token the Ksp of practical wastewater because it quite different with theoretic Ksp at different pH; the theoretic and practice addition were proportioned and it commonly reached 1:300.The precipitation efficiency of Na2S at different pH and the effect of Ca2+ was determined.

ABSTRACT It is because that the excellent acceptors for maize transgenic engineering are insufficient in our country, especially in the southwest mountain areas of china and hereditary variation regularity for the two characters such as efficiency of embryonic callus induction and number of regenerating plant (these two characters were abbreviated to the nduction efficiency and number of regenerating in the following of the paper, respectively), which hint the maize culturing capacity, is not very clear. Therefore, aiming at picking out superior acceptors, we had made systematic researches on the two characters with combing traditional quantitative-character genetic analyzing methods such as single-factor genetic mating design, diallel crossing genetic design, genetic effect analyzing method and the modern molecular locating method such as QTLs'. The main results are followed.(1) 50 superior inbred lines and about 30 crosses in our country, especially in the southwest of China were used for identifying and selecting the superior genotypes in the above two investigated characters under the same culturing condition in 2000 and 2001. There was very significant difference among the genotypes in the both characters. But the two characters were not certainly related. Some genotypes such as 18-599 and 18-599 were very good in them. For some ones such as zong 31, induction was higher than 18-599 and 18-599 in the efficiency, but it was only 1/3 to the later in regenerating number. In some genotypes such as S37, R08, R15, P138, A318, induction efficiency was just about 3% and scarcely any regenerating plants were got. On the whole, hybrids acted better than inbreeds in the both characters.(2) Two kind of inbreeds were selected as parents of the Griffing's method 1. 18-599 and 18-599 and the inbred line zong 31 are one kind because they are not only superior in the characters of maize cross breeding, such as CA, resistance to disease and the important agricultural characters, but also excellent in transformation characters as the induction and regeneration.
针对我国、特别是西南山地所需玉米转基因工程育种优良受体极为匮乏和反应玉米幼胚培养能力的2个主要性状,即玉米幼胚胚性愈伤组织诱导率和胚性愈伤组织绿苗发生数的遗传变异规律十分不清楚的实际情况,本研究从筛选玉米转基因工程所需要的优良受体入手,采用单因素遗传交配设计、双列杂交遗传交配设计、世代基因效应等传统数量性状分析方法,以及现代分子标记定位主效QTL分析方法,对玉米幼胚胚性愈伤组织诱导率和胚性愈伤组织绿苗发生数等2个性状进行了较为系统的分析研究,取得以下主要研究结果:(1)于2000年和2001年通过对我国、特别是西南地区近50份优良自交系和近30个杂交组合,在相同培养条件下,对幼胚培养胚性愈伤组织诱导率和胚性愈伤组织绿苗发生数等2个幼胚培养能力性状进行了筛选与鉴定,发现玉米不同基因型具有完全不同的幼胚培养胚性愈伤组织诱导率和胚性愈伤组织绿苗发生数,但幼胚培养胚性愈伤组织诱导率与胚性愈伤组织绿苗发生数并不具有必然的相关关系,有的基因型,如自交系18-599和18-599在胚性愈伤组织诱导率和愈伤组织绿苗发生数等2个性状都表现相当优异;有的基因型,如自交系综31,仅幼胚培养胚性愈伤组织诱导率性状表现高于19-599和18-599,但在胚性愈伤组织绿苗发生数这一性状则与它们有相当大的差距,仅为19-599和18-599的1/3左右;有的基因型,如S37、R08、R15、P138、A318等玉米自交系不仅幼胚培养胚性愈伤组织诱导率很低,平均仅在3%左右,而且胚性愈伤组织绿苗发生数表现也很差,基本上没有分化成苗。

The radiation by non-thermal plasma can accelerate formaldehyde thansform and make an increase of 29.61% in depurated efficiency. The surface modification makes no obvious difference in depurated efficiency. The chemical modification avails formaldehyde reduction and ACF coated with nano- TiO2 is the best of all that can enhand the depurated efficiency to 94%. The great influence of parameters on depurated efficiency , such as applied voltage and reaction time , shows that an increase in either applied voltage or reaction time enhance formaldehyde conversion.
