If the use of an aerosol can in some remote spot can h*e an o*otic impact on living organi*s at opposite ends of the world, does it not follow that all things on earth are somehow intrinsically connected?

如果在一个遥远地方使用一罐烟雾剂，就会对地球另一端的生物有机体产生影响。那么，我们是否也可以将其解读成：地球上的一切事物在本质上都或多或少地存在联系呢？

According to the phytosociological theories and methods of Braun-Blanquet's school, the regional savanna vegetation of the dry-hot valleys of Yuanjiang river had been investigated. Based on the principle of fidelity degree, the typical 110 releves taken from every sampling stands of the dry-hot valleys were sorted up from below to upper into 15 Associations, then into 5 Alliances, 2 Orders and 1 Class. A synoptic classification system of Class-Order-Alliance-Association was established for the purpose to reflect deeply the characteristics of all syntaxa there in the aspect of plant component and their abundance-dominancy, presence, cover coefficient, life form, growth form, and ecological environment, community structure, species types and so on.

采用Braun-Blanquet植物群落学研究的理论与方法，对云南元江中上游干热河谷分布的植被进行考察研究，把各处取得较典型的110个样地记录按确限度的原则由下而上归类成15个群丛、5个群属、2个群目和1个群纲，建立了元江干热河谷萨王纳植被群纲—群目—群属—群丛分类系统综合表和15个群丛表，以全面深入反映全干热河谷植物群落各级分类单位中各植物种类组成的多优度、存在度、盖度系数、生活型和生长型等特征及其群落结构、生态环境和种型类别。

Studies on the regulation of malignant phenotype expression in a mouse plasmocytoma cell line (SP2/0) by means of cellular engineering techniques of cell hybridization between the fusion of the mouse myeloma cells with rat intermediate or late erythroblasts.

三、利用细胞杂交的细胞工程手段，首次系统地研究了大鼠中幼、晚幼成红细胞与小鼠浆细胞瘤（SP2/0）细胞融合后恶性表型的表达状态，分析自然去核前红细胞胞质对骨髓瘤细胞恶性增殖的调控作用，以及晚幼期固缩核重新被激活的可能性。

It is well known that the large lattice mismatch (16%) and thermal expansion coefficient mismatch between GaN and sapphire substrate are the main origins of TDs. By new growing technique of LEO, we acquired high quality GaN films almost free of TDs. The stress characteristics in GaN films with MLTB growing technique is dependent on growing systems and conditions, and the changes of stress and dislocation density are rightabout; Combining buffer layers of high temperature and low temperature is first developed to growing GaN films with low dislocation density, and the mechanism of lowering TDs density is that the first buffer layer of high temperature can make nuclear in second buffer layer of low temperature bigger. This technique also can restrain yellow luminescence effectively.

众所周知，晶格失配和热应力失配是GaN异质外延中位错产生的主要原因；为此，我们对几种降低缺陷的MOCVD外延生长方法进行了新的尝试，其中尝试了侧向外延生长技术，得到了低位错密度（小于10〓/cm〓）、高质量的GaN外延层；尝试多低温缓冲层法，发现材料中的应力特性与生长系统和生长条件有关，材料中的应力与位错密度按相反方向变化；首次尝试高低温联合缓冲层法，材料中高温缓冲层可以使随后的低温缓冲层中成核颗粒增大，从而导致随后高温GaN外延膜中位错密度降低，并且能够有效地抑制黄光峰。
