The temperature of cold injury was abo ut 0 ℃ to 15℃,While hot injury would appear when temperature got to 36℃.These ind icat ors were varied in different species,and the greatest difference was the temper ature of cold injury.Growth would be poor in summer under full illumination,whi le part shading was beneficial.The best condition was 70 percentage of sh ading for Araceae and 50 percentage of shading for Agavaceae.The need for soil moistu re was strict.Most of species would grow normally in 65 to 85 percentage of soil m o isture.The characters responsed to illumination,temperature and soil moisture w e re consistent with their original ecologic environment.

其最 适生长温度在16-35℃，除酒瓶兰外，低于10℃时均表现生长停滞状态；寒害温度差异很大，天南星科为0-15℃，龙舌兰科为0-10℃，大多数植物在36℃会产生热害；光照对其影响较大，夏季这两科植物在全光照下长势差而在一定荫蔽的条件下有利生长，最佳荫蔽度天南星科为75％，龙舌兰科为50％；这两科植物对土壤中的水分含量要求较高，大多在土壤含水量70％以上才能正常生长，这些光、温、湿的反应特性与其起源地湿热和荫蔽的生态环境相吻合。

The results showed that:(1)IRBB21 was resistant to all the strains except T7147,astrain from Japan belonging to the Japanese racial group 2,whereas Minghui 63 and 6078 weremoderately susceptible to most of the strains tested;(2) The resistance reactions of the hybrids derivedfrom IRBB21 appeared to be the same as that of IRBB21,whereas that of the hybrids derived fromMinghui 63 and 6078 were more susceptible to BB than the two restorers.

结果表明，IRBB21除不抗日本的T2菌系群外，对所有其它供试菌株均表现高抗，恢复系明恢63和6078对供试菌株多为中感，以明恢63或6078配组的杂交稻的抗性极差，而源于IRBB21的杂交稻的抗性与IRBB21基本相同，因而证实Xa21基因确为在我国极具应用价值的抗性基因，完全可以用于杂交水稻的白叶枯病抗性改良。

结果表明：翁牛特旗近50年平均气温、日最高气温、日最低气温随时间均呈增加态势；日最低气温的增加量是日最高气温的11倍；1月最低气温的线性增加率为8.77℃/100 a，7月最高气温的线性增加率为3.12℃/100 a，其结果导致日较差减少；20世纪80年代后期年平均气温、日最高气温、日最低气温显著升高。

The multipath effect is an avoidless problem which the tracking radar and the searching radar among CIWS has to face. This paper analyses the form of the multipath effect on geometry, emphasizes the distance difference between the direct wave and the reflected wave, according to this inherent characteristic, the paper introduces the theory of HRR to the design of radars among CIWS, discusses the spike pulse technology and ultra wide hand technology which often be used, finally proposes the method of time-frequency code to obtain the high range resolution and avoid the multipath effect.

多路径效应是近程反导武器系统中的搜索雷达和跟踪雷达均无法避免的问题，文中分析了多路径效应形成的几何原理，并根据多路径效应中的直射波与反射波具有路程差的固有特性，将高距离分辨率雷达信号理论引入到近程反导武器系统的雷达中，讨论了实现高距离分辨率的窄脉冲和超宽带技术，最后提出了目前较易实现的时间－频率码合成高距离分辨率的办法。

The four-week twice immunized hamsters acquired anti-MP in-fection capacity in local respiratory tract,as a result that swab culuturepositise was belove that of unimmunization group,and that only onehumster's lavage fluid culture was positive in immunization group.How-ever,unimmunization group positive rate of swabs and lavage fluid cul-ture was very high.This hinted that local respiratory tract's anti-MPinfection capacity was weak at the primary infection and the ability de-veloped gradually.4.The sIgA change in broncheal-lung lavage fluid.

而未免疫组咽拭子和支气管肺泡灌洗液MP分离培养的阳性均很高，说明在初次感染时，呼吸道局部防御清除MP的作用差，但随着时间的推移，其灌洗液培养的周次阳性率有下降趋势，MP培养的滴度亦随之降低，说明在感染以后随着时间的推移，呼吸道局部逐渐产生了防御、清除MP感染的作用。

With Fisher ratio and variance analysis method it was found, the withinclasses and betweenclasses features of Reed, Chinese Tamarisk and Sea blite were all located in 350700nm and 350550nm respectively.

经Fisher比率法和方差分析发现芦苇、柽柳、翅碱蓬类内和类间特征均分别位于350～700nm和350～550nm之间。

The choiceness varieties of Canarium album were tested in three different places of Guangdong. The study researched the 3-4a trials after engrafting, the results were as follows:(1) The results of variance anaylsis indicated that there were highly significant differences in yield per plant and yield per crown projection area among clones, and the height, stem diameter and crown side were highly significant in some test sites. It showed that genetic diversity existed in yield per plant among clones, and selecting high yield clones were effective.

在高州市大坡镇、古丁镇以及茂名市八一林场三个试点开展橄榄优良品系扩大试验，嫁接后第3年及4年的结实及生长结果如下：（1）方差分析结果，无性系间单株产果量、单位树冠投影面积产果量均达极显著差异水平，树高、径粗和冠幅在有的试点达极显著差异、有的试点无显著差异，表明无性系间结实存在着真实的遗传差异，通过无性系测定选择的高产无性系有效。

Results:The clinical manifestation of postoperative gastroparesis was abdominal distention,vomit,no obvious celiodynia and normal gas discharge by anus in majority patients,weak enterocinsia was shown by barium meal X-ray of alimentary canal opacification,and unobstructed anastomotic stoma shown by gastroscopy.52 patients relieved from gastrointestinal decompression,nutrition support,water-electrolyte metabolism balance,gastrointestinal motility medicine and combined integrated traditional chinese medicine and western medicien treament.

Firstly the thesis made study on stress field、 displacement field、 yielding part in colluvial deposit and accretion before water accumulated and after water accumulated and made the conclusion that slope failure will take place easier in colluvial deposit than in accretion.The stability computation indicates that stability will decline either for colluvial deposit or accretion bank and decline more rapidly in colluvial deposit than accretion bank.

论文首先对崩坡积、冲洪积岸坡蓄水前后的应力场、位移场及塑性区的变化进行对比，结论为崩坡积体岸坡遇水比冲洪积体岸坡更容易发生破坏；通过对岸坡的稳定性计算，两种岸坡在蓄水后和水位骤降时的稳定性均明显降低，崩坡积体岸坡降低更为显著，且其天然稳定性较冲洪积岸坡为差。
