一、問題和研究的經过在全国生产大跃进、大鬧技术革命的年代,劳动心理学的任务不仅是、或主要不是、研究怎样改变生产者的主观状态,如操作方法,来适应客观条件、如机器設备等了,而应当研究怎样促进生产者改变客观条件,如改革工具、創造工具、来适应飞速发展的生产需要了。劳动心理学工作者应当总結工人創造性思惟活动的規律,在生产条件下应用这些规律,为創造发明准备条件,縮短創造发明的过程,使工人羣众有效地、快速地完成一項項的技术改革——創造性活动。

Field experiments were conducted in a maize (Zea mays L.)field of a calcareous fluvo-aquic soil in North China Plain for studying the fate and ammonia loss of urea-N applied at seedling stage,as well as the effectiveness of coated calcium carbide(CCC) in reducing N loss and in improving the yield efficiency of *** show that:(1) For the surface-broadcast treatment ammonia volatilization (measured with micro-meteorological technique)took place quickly,reached the peak 20-26hr after application,and then declined gradually;the cumulative ammonia loss approached the maximum 188hr after application (3.% of the N applied),and increased only to 3.% 284 hr after application;the latter accounted for 71% of the total loss (45% of applied N).(2) In the case of point placement at a depth of 5-10 cm,ammonia loss 188hr after application was only 12% of the N applied,accounting for 40% of the total loss.(3. There was no difference in total loss between the application depths of 6cm and 10 cm,the loss of them was 3.% and 29%,respectively.(4) Total loss of N applied at lower rate (40kg N/ha)with point deep placement at 6cm depth was found only 4% of the N applied,it rose up to 3.% when the rate of application increased to 80kg N/ ha.(5) The nitrification inhibitor,CCC,seemed to enhance N loss of urea rather than reduce it,and did not show any benefit effect in improving the yield efficiency of urea,which is presumably due to the high potential of ammonia volatilization in the soil and climatic conditions under investigation.

Alzheimer’s disease (AD) is the most common form of brain dementia characterizedby the accumulation of β-amyloid peptides (Aβ) and loss of forebrain cholinergicneurons.Aβ accumulation and aggregation are thought to contribute to cholin-ergic neuronal degeneration,in turn causing learning and memory deficits,but thespecific targets that mediate Aβ neurotoxicity remain ***,accumu-lating lines of evidence have demonstrated that Aβ directly modulates the func-tion of neuronal nicotinic acetylcholine receptors (nAChRs),which leads to thenew hypothesis that neuronal nAChRs may serve as important targets that medi-ate Aβ *** this review,we summarize current studies performed inour laboratory and in others to address the question of how Aβ modulates neu-ronal nAChRs,especially nAChR subunit function.

In this paper a compilation of 271 heat flow values of the Southwest Pacific (145°E-170°W and 0--40°S) is presented with division of data categories, quality gradation add sedi-mentary environment classification. The dominating effect of environmental types of thebasins on the characteristics of statistical distribution of heat flow data is illustrated. A plotmatch of heat flow and ocean depth versus age of oceanic crust in the marginal seas with thetheoretical curve of thermal evolution derived for the world oceans has been accomplished forthe first time. The result reveals an approximate similarity in the mechanism of their evolution.

最近,在“基本粒子”的结构模型方面,做了一系列的工作。认为“基本粒子”是有内部结构的,是由更基本的“基础粒子”构成的。本文从这个观点出发,假定重子是由三个基础粒子构成,用协变场论的方法,计算了（3.2）→（1/2）重子流矩阵元。所得结果表明,在我们的重子流矩阵元中,含有二个结构形状因子N（q）和T（q）,我们的结果包括了过去S（?）理论的结果,即:在忽略T（q）项情况下,就是S（?）理论的结果。但是,

黄土地区土壤中全磷与有效磷含量均有由北向南逐渐趋增的趋势,一般是:灌淤土较高,(土娄)土、褐土与黑垆土次之,黄绵土、灰钙土和黑钙土又次之,风沙土较低。土壤有效磷可分为4级,5.5ppm可作为土壤缺磷临界值,5.5—10.5 ppm作为边缘值。黄土地区土壤中各形态磷占全磷比例以Ca-P最高,有机磷与O-P次之,Al-P、Fe-P和水溶磷较低。土壤有机磷及其与无机磷的比值与土壤肥力有密切关系,闭蓄态磷及其与磷酸钙的比值似与土壤风化程度有关。磷肥施入土壤后,早期固定较快,20天后渐趋平稳。在高钙土壤中,施入的磷主要转化为Ca-P,低钙土壤则转化为Ca-P,Al-P和Fe-P。黄土地区磷肥施于低肥土壤或中肥土壤中其肥效优于高肥土壤;施于灌溉土壤优于旱作土壤;与氮肥配施优于单施。
