With the deeping of the trough and the westward moving of the tropical cyclone, the low level vortex and wind shear line extended along a southwest - northeast orientation over the Yangtze River. On the effect of high, middle and low latitude systems, a rainband in southwest - northeast orientation formed gradually.

随着阻塞形势的发展和热带气旋的西移北上，经向环流加强，主要影响天气系统——低空的低涡切变线沿西南－东北方向伸展，在高、中、低纬度天气系统的共同作用下，一条西南－东北走向的雨带逐渐形成。

There are Hannan block in the northwest and Huangling block in the east. Its extended direction is east-northeast in the northwest area, east-west in the middle area and east-northeast in the southeast area,being a southwestward arc made up of many thrust nappes.

该带西北端受汉南地块限制，东部有黄陵地块的阻挡，其展布方向由西北部的北北东向、中部的近东西向、至东南部的北东东向，呈一向西南凸出的弧形，是由一系列呈向西南突出的巨型逆冲推覆断裂带构成。

The effect of the spring thermal depression generally holds for almost a quarter of a year in the region, and the highest frequency and intensity respectively occur in April and May. It has an obvious diurnal variation pattern and gets stronger year by year.

研究结果表明：西南地区热低压具有明显的地域性，较少移动；春季我国西南地区近1/4时间受热低压影响，4月份热低压出现频率最高，而5月份的热低压最强，热低压存在明显的日变化且其强度有逐年增强的趋势。

Using the surface observation data and NCEP reanalysis data, spring thermal depressions in the southwest of China are classified into a local type and north-intruding type. Then the position and strength indexes are defined, the space-time distribution and numeral characteristic are analyze and their formation rules and mechanisms are studied for improving the accuracy of weather forecast. The results indicate that the thermal depressions are mostly regional and stationary.

利用地面常规观测资料和NCEP再分析资料，把我国西南地区春季出现的热低压分为本地生成型热低压和北方移入型热低压两种类型，定义了热低压的位置指数和强度指数，并以此讨论两种类型热低压的时空分布特征，对西南热低压进行定量描述以及研究其形成规律和机理，以提高天气预报的准确率。

Over the northern SCS, analysis results find the lower troposphere is convectively unstable during the entire onset period. The favorable atmospheric conditions for convection are attributed to low-level moisture convergence caused by the frontal southwesterly flow during the first stage, and the retreat of western Pacific subtropical high and warm-moist southwesterly flow from the Bay of Bengal during the later stages.

分析结果显示，在1998年南海夏季季风肇始发展过程中，南海北部的大气大多呈现对流不稳定的形势，第一阶段锋前西南气流造成低层强烈的水气辐合，第二阶段之后锋面远离且太平洋副热带高压东退，来自孟加拉湾的西南气流夹带大量暖湿水气使得南海北部在整个季风肇始期间都是有利於对流的状况。

Main results were as follows:(1) The number of wild animals and plants species protected in reserves increased logarithmically with the increase of nature reserves.

研究结果如下：通过回归分析发现，随着自然保护区的增加，受保护的野生动物物种总数呈现对数增长的趋势，由此得到西南地区受保护的野生脊椎动物物种总数为2426种，为我国野生脊椎动物物种总数6347种的38.2%；西南地区受保护的野生高等植物物种总数为20965种，是我国野生高等植物物种总数30000多种的近70%。

Based on T213 numerical forecast products, the abrupt city flood caused by heavy rain in Kunming, Yunnan province on June 24, 2006 is analyzed. The results indicate that the event has a close relation with the southward movement of upper shear line and the peripherad southwest warm and wet airflow.

2006年6月24日云南昆明发生了当年最为严重的一次城市洪涝，利用T213数值预报产品资料对这次突发性洪涝灾害的气象成因进行了诊断分析，结果表明此次强降水与高空切变线南压及西太平洋副热带高压外围西南暖湿气流有关，高空切变线南压有利于引导北方冷空气南下入侵，而西太平洋副热带高压外围西南暖湿气流为此次洪涝灾害的爆发提供了丰富的水汽。

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。
