At last the paper realized the advantages and disadvantages of passive solar building and adnvanced some suggestions in future research. From another point, the paper logged the process of the building of the experimental equipment and the mounting of the measurement equipments that accumulated some operating experimence.Carrying experiments, calculating and analyzing the experimental data for more than 2 years, the paper gained some constructive conclusions. In winter the indoor air temperature and RH are lower than comfort criteria, but people feels very comfortable in the passive solar house. The thermo-circulation formed by Trombe wall play an important role in improving indoor air temperature and RH. Based on the analogy analysis theory, the natural convection heat transfer in the air gap can be treated as superposition of two natural convection heat transfer processes occurring over isolated isothermal vertical flat plate, in this case namely the massive wall and glazing. Two empirical formulas for Q and Nu are obtained. The investigation shows that the optimal time to open the damper should comply with the period that the thermo-circulation happens which can be controlled by thermal response characteristics of Trombe wall surface temperature and air temperature in the air gap.

经过两年多的实测和计算,根据传热学、流体力学、统计学等学科的基础理论,对大量数据进行整理归类、分析讨论,主要得到如下结论:(1)冬季,含有特朗贝墙体的被动式太阳房室内热湿环境较舒适性标准偏低,但人体感觉比较舒适,特朗贝墙体形成的热循环通风在调节室内温度和相对湿度方面起到很大的作用;(2)特朗贝墙体空气间层自然对流可以看作是两个等温独立大平板的自然对流换热过程的叠加,通过与大平板自然对流理论类比获得了计算热循环过程中对流换热量的经验公式;(3)特朗贝墙体通风口的启闭可以根据玻璃幕墙内壁面温度、蓄热墙体外壁面温度和空气间层进出口空气温度之间的关系来进行控制,从而有效地阻挡冬季冷循环的发生;(4)夏季,如没有有效的通风降温措施,被动式太阳房内会产生明显的过热。

The implementing process of TI in EMS is partitioned into two periods including product conception development and product technology development. The model of product conception development is built which is composed of demands identifying, technological modules identifying and conception appraisement. In the period of product technology development, the identification model of knowledge on new product is constructed at first. Enterprises should beware of selection and integration of the relative domain-specific knowledge, and do product innovation continuously by product platform approach based on the integration of outer technology resource efficiently. The view is put forward that Chinese EMI enterprises should do TI with self-innovation, and only by this way could enterprises build undependent technological capability and keeping product innovation continuously.

Clonidine (20ug/bilateral), an alpha agonist, produced similar effect as NA; while phentolamine (10ug/unilateral), an alpha antagonist, brought about an enhancement of AA, This phenomenon was observed in the acupuncture effective group, but not in the acupuncture uneffective one. However, propranolol (10ug/unilateral), a beta antagonist, had no effect on AA in these two groups.

The cause of hard agglomerate formation and its effect on sinterability were investigated. The water-washed ZrO〓-Y〓O〓 powders were found to be greatly made up of hard agglomerates. The ethanolwashed powders also contained a few of hard agglomerates because of uneffective dehydration. Beside, ethanol volatilizes in advance of water during drying because ethanol has a lower boiling point than water, so steric effects of ethanol won't act. However, nearly no hard agglomerate formed in the azeotropic distilled powders, because of effective dehydration and higher boiling point for n-butanol.

研究指出,水洗工艺所得ZrO〓-Y〓O〓粉末几乎完全由硬团聚组成;乙醇洗涤工艺的脱水效果不是很好,并且由于乙醇的沸点比水低,以致在干燥过程中残留乙醇比水先挥发,乙醇的空间位阻效应不能有效地发挥作用,因此,仍然可以导致产生一定量的硬团聚;而共沸蒸馏工艺的脱水效果最佳,且正丁醇的沸点比水高,干燥时残留正丁醇比水后挥发,从而正丁醇的空间位阻效应可有效地发挥作用,因此避免了在煅烧过程中形成Zr-O-Zr键,即共沸蒸馏粉末中不含硬团聚。

Pit corrosion is a main kind of localized corrosion. The process of forming pit corrosion includes three stages-formation of pit source, development of pit cave and forming occluded corrosion cell. Molybdate series inhibitors can be inhibitive, for it can control three stages of pit development. First, there is apparent synergistic effect between molybdate and phosphate, which can suppress formation of pit source. Second, there is apparent passivation of molybdate inhibitor according to electrochemistry analysis, which let oxidation film in unoccluded cave repassivate.

首先,钼酸盐与磷酸盐或硅酸盐复配的缓蚀剂具有较理想的缓蚀性能,并且有明显的协同作用,从而能抑制部分点蚀核的产生;其次,钼酸盐复配缓蚀剂的使用,从电化学的角度分析,具有明显的钝化性能,且钝化区间较宽、维钝电流密度较小,从而能使未封闭的蚀孔或点蚀核附近的氧化膜再钝化,得到有效的修复;最后,对于还有部分蚀孔发展成为闭塞腐蚀电池的情况,钼酸盐、磷酸盐能进入蚀孔内部并且在酸性条件下生成铁钼磷酸盐,从而有效地减缓了点蚀的恶化,抑制了腐蚀的发展。

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%.
