发展柴达木盆地盐湖农业的资源基础

 基于柴达木盆地的地理、气候、水资源和盐生植物等自然条件,综合分析了该地区发展盐湖农业的资源基础,重点讨论了土地利用现状的特点及存在的问题。结果表明,柴达木盆地以盐渍化的土地为主,区域内积温较多、热量条件较好,咸水、微咸水资源及动植物资源丰富;农业用地仅占土地总面积的0.17%,有大量宜农土地未被开发,撂荒面积大;草地占土地面积的46.64%,但海拔、气候、交通等条件限制其利用;林地占土地总面积的2.87%,破坏较严重;盐碱地占总土地面积的11.68%,且资源丰富,几乎未被利用。柴达木盆地资源基础丰厚,开发潜力巨大,建议在该地区建立农业示范园区,发展盐湖农业,加强盐生植物研究,合理开发利用盐碱地资源。

The impact of W. K. Röntgen's discovery on the use of internalizable sources of ionizing energy in diagnostic and therapeutic nuclear medicine

The early history of cathode rays, X-rays and a third kind of natural radiation from several minerals and atomic fission is described. In this way the fundamental concept of radioactivity, laws of decay and atomic models were developed. With artificial radioactive isotopes, new tailored radiopharmaceuticals could be introduced into metabolic research, medical diagnostics and therapy. Von Hevesy's concept of the dynamic state of body constituents led to examination of the locations and movements of labelled atoms and molecules as a function of time. That was the birth of nucler medicine. The principles and value at the molecular level of several specific tracer studies in research and diagnostic or therapeutic use are explained. Typically, diagnostic tests with tracer agents are non-invasive and have low radiation exposure. Competing with other diagnostic and therapeutic modalities, nuclear medicine is a speciality in its own right. But there are moves to classify it as a subspecialization of other organ-oriented clinical disciplines. That is a misunderstanding of the radiologist's role and does not answer the question: What is the best way of woking for the patient? New horizons in diagnostic modalities, biochemistry, immunology, imaging and the use of immunogenic therapeutic agents demand a continuous cooperation within interdisciplinary teams. That is as necessary with radiologic departments, participating in changed organizational structures, as with other clinical departments.

How to Apply Student-centered Teaching Techniques in a Large Class

It is very common to have a class of 50 or more students in Chinese schools, and teaching a foreign language effectively to a large class is really hard work. In order to change the teacher-centered teaching model into the student-centered one, Teachers should keep students＇ needs, interests, and learning styles in mind, apply several kinds of teaching techniques, organize different classroom activities and encourage, praise and appreciate both students＇ success and learning process all the time. If teachers place more responsibility in the hands of students, serve as ＂presenter or facilitator of knowledge＂ instead of ＂source of all knowledge＂, they can greatly motivate students to learn the language in a very active, cooperative and effective way. After all, people learn by doing, not only by watching and listening.
