Methods Model was fitted by the historical data of typhoid and paratyphoid of Jiangsu Province.

用1991年1月至2000年10月江苏省伤寒副伤寒发病资料建立模型，以2000年11月和12月的发病资料作为模型预测效果的考核样本。

The results showed:among the 7 isolates, five isolates of HY3、GY1－3、ZJ1－1、HP1、FC3 had same colony shape, irregular shape, liquidlike, slimy, opacity with smooth surface;the other two isolates had same shape, irregular shape, dry, opacity with coarse surface. By inoculating eucalyptus with the 7 isolates, the plants were infected apparently, and the young plants of eucalyptus in control experiment with tap water were not infected. By cultivating eucalyptus cuttings with the bacterial suspensions without EPS, the incidence of disease was very distinct,but compared with the former bacteria suspension,the incidence of disease has decreased at different degrees. By screening out two isolates of strong pathogenicity and two isolates of weak pathogenicity from the 7 isolates,making the bacterial suspensions with them to inoculate the young plants of eucalyptus, two treatments of cutlings and ramets with rats were set with 5 repetitions in every treatment, the results of data analysis showed: for the cutlings, the bacterial contents in upper and middle parts、upper and lower had significant difference;for ramets with roots, the bacterial contents in upper, middle parts, lower had significant difference between each other; For both the cutlings and ramets with roof, the bacterial contents in xylem and phloem had significant difference. The interaction between vertical and horizontal parts for the bacterial content had significant difference. For the two isolates of HY3 and 93B which were screened out at last,their activities of the cellulase were: 1.955ug/ and 1.288ug/ respectively, and had significant difference; the activities of pectase were: 1.325 ug/and 1.24ug/ respectively, and had no significant difference. The content of EPS extracted from the two isolates of HY3 and 93B was very different: 7.08x10-8ug/cell and 5.17x10-8ug/cell.

结果显示：7个菌株中，其中5个菌株HY3、GY1－3、ZJ1－1、HP1、FC3的菌落形态相同：不规则形状、流体、粘性、不透明、表面光滑；另外2个菌株93B、GN1菌落形态相同：不规则形状、干燥、不透明、表面粗糙；用7个菌株接种剪根桉树苗，发病情况非常明显，而自来水对照实验中桉树苗却不发病；无EPS菌悬液培养桉树剪根苗，发病率也很明显，但是相比原菌液，则发病率有不同程度的下降；从7个菌株中间筛选出来2个强致病性菌株和2个弱致病性菌株，用它们配制菌悬液培养桉树苗，设置剪根和不剪根两个处理，每个处理设置五个重复，数据分析结果显示：对于剪根苗，上部和中部、上部和下部的含菌量有显著的差异，中部和下部含菌量差异不显著；带根苗，上部、中部、下部含菌量彼此之间差异显著；不管是剪根苗还是带根苗，木质部和韧皮部含菌量之间的差异都非常显著；上中下与木韧交互作用中，含菌量差异非常显著；最后筛选出来的强弱2个菌株HY3和93B，它们的纤维素酶活性分别为：1.955ug/和1.288ug/，具有显著的差别；果胶酶的活性分别为：1.325 ug/和1.24ug/，没有显著的差别，而且HY3和93B两个菌株细胞分泌的胞外多糖的含量差异很显著，分别为：7.08×10-8ug/cell和5.17×10-8ug/cell。

Besides spring and autumn, summer is the peak season of pityriasis rosea also. Pityriasis roses presents atypical lesions, locations and severe pruritus. The pathogenesis of pityriasis rosea may be related with HHV-6 infection.

除春秋季外，夏季也是玫瑰疹的高发季节；其可表现为不典型的皮损、不典型的发病部位及伴有显著瘙痒，值得临床医师重视；其发病可能与HHV-6感染有关。

This paper provided a statistical analysis of 2000 patients with allergicdiseases in Xi'an and the surrounding area.The results of the analysis show-edg:(1) the incidence of the allergic disease had little difference be-tween male and female, while it was higher in youth and children; respi-ratory allergy, skin allergy, and pollinosis were main types of the disea-ses;(2)the positive ratio of the skin tests of atopic inhalant allergenswas 66.4%,among which, mite, pollen, mold and house dust were high...

本文分析西安及其周围地区2000例变态反应病的情况，结果表明：两性发病率基本相同；青年期和儿童期为好发病期；过敏性呼吸道疾病、皮肤疾病及花粉症是主要发病类型；特异性吸入性过敏原皮试阳性率为66.4%，其中螨、花粉、霉菌的阳性率最高，室尘次之，是本地区过敏性疾病的主要过敏原；采用免疫治疗总有效率为90.15%，非特异性免疫调节治疗可增加免疫治疗效果。

The results showed that the potato late blight displayed marked ascending trend,and the influence rate of potato late blight in the field was 3.543 7% per year.

结果表明：研究区域马铃薯晚疫病历年发病面积比例呈显著上升趋势，发病面积比例以每年3.5437%的速度增加。

BACKGROUND: Transfusion has been demonstrated to be associated with pneumonia in injured patients, and blood of older storage age may potentiate this morbidity.

背景：已证明创伤患者中输血与肺炎的发病有关，并且储存时间长的血液导致发病的可能性更大。

Background: We hypothesized that patients with cerebral infarction on preadmission warfarin have less severe neurological deficits on admittance, less severe neurological deficits 1 week after the onset of cerebral infarction and a larger improvement as to neurological deficits within 1 week of acute cerebral infarction.

背景：本研究假定早期使用华法林治疗的脑梗塞患者，其入院时神经功能缺损程度较轻，发病一周后神经功能缺损较轻，发病一周后的神经缺损恢复程度较大。

Supratentorial and infratentorial tumors predominate from birth to 3 years and from 4 to 11 years respectively.

幕上肿瘤的常见发病年龄为从出生到3岁，而幕下肿瘤的常见发病年龄为4～1l岁。

But when a individual has developed the disease in exposed case we cannot measure the probability of who would have developed the disease even if he had not been exposed .

但是当一个个体在暴露的情况下发病时，我们无法测量到假若该个体不暴露时也可能发病的概率，因而，我们无法测量暴露对个体产生的效应。

Finally, according to market conditions and market products this article paper analyzes the trends in the development of camera technology, and designs a color night vision camera.
