Ginsenoside R〓 was synthesised only in the root parts. Therefor, it is the characteristic component of ginseng root.

人参皂甙R〓仅能在地下部根中合成，茎叶均无合成能力，因此R〓是人参根的特征性成分。

The presence of early CT signs has been reported to be a predictive sign of hemorrhagic complications after reperfusion therapies[4, 5, 13 18]. Our study has also demonstrated that the rate of symptomatic hemorrhagic complications showed a tendency to increase as the grade of early CT signs increased, although a statically significant difference was not proved. A grade III CT sign may be a predictive sign for hemorrhagic complications after reperfusion therapy. In contrast, the presence of a grade I CT sign may not contraindicate reperfusion therapy.

本研究也显示：尽管彼此间均无统计学显著差异，但血管内再通治疗后症状性出血并发症的发生率，在深部大脑中动脉分布区未出现早期CT征象的患者、出现I级早期CT征象（细微低密度区局限于岛叶，基底节区正常）的患者、出现II级早期CT征象（部分壳核后外侧区出现低密度）的患者、出现III级早期CT征象（整个豆状核区均出现低密度）的患者中，呈逐渐增加的趋势。

The distribution of the qualitative characters The performance of the 39 chief qualitative characters were observed and recorded,according to the test method of morphological characters in the .The results of distribution proportion of each character in cultivars group showed that the distribution of 32 characters(number of ray flower rings,floret curliness,shape of leaf base,size of stipule and so on) were very asymmetrical with near or above 70%cultivars concentrated upon one or two performance, however,the distribution of the other 7 characters(floret type,surface color of outer floret,back color of outer floret,color of disc floret,claw in base of sinus between lateral lobes,stem erectness and stem color) in the cultivars group were relatively symmetrical.

质量性状分布参照《菊花DUS测试指南》的形态性状测试方法，观察记录大菊39个主要质量性状的表现，计算各性状的表现式样在品种群内的分布比例，结果显示舌状花的重瓣性、花瓣曲反状况、叶片基部性状、托叶大小等32个性状的表现式样在品种群内分布极不均匀，接近或超过70%的品种集中在性状的1种或2种表现式样中；而花瓣形状、外花瓣表面色、外花瓣背面色、花中心部颜色、叶裂刻基部有无突起、茎的曲直性和茎色等7个性状的表现式样在品种群内的分布则相对均匀。4。

Results:Main imaging features of APK were as follows:On abdominal plain films showed the lobalate renal enlargement in 46 cases,calcification of polycystic wall in 14 cases,renal calcium milk in 5 cases,60 cases were showed separation,deform and longthend of renal pelvis on intravenous urography and retrograde urography,5 cases were showed renal enlargement on retroperitoneal pneumography,on CT scans in 25 cases showed mulltiply cysts with thin wall,unecho liquid shadows were showed on B-mode ultrasound.

结果：成人多囊肾的主要影像学征象：腹部平片(46例)显示肾影呈分叶状增大；囊壁钙化(14例)；多囊肾合并肾钙乳(5例)；肾盂造影(60例)，表现为肾盂、肾盏相互分离、变形、拉长；腹膜后充气造影(5例)：表现为肾影增大肾影与邻近器官之间的关系，其界限清晰可辨；CT扫描(25例)：表现为肾内多数大小不等的薄壁圆形低密度区；B型超声(47例)表现为肾内多个类圆形无回声的液性暗区。

Results The main imaging of adult polycystic kidney disease signs: abdominal plain film (45 cases) showed renal shadow was lobulated increase; cystic wall calcification (14 cases); polycystic kidney disease and renal milk of calcium (8 cases); pelvis angiography (61 cases), the performance of the renal pelvis, renal calices separated, distorted, elongated; retroperitoneal inflatable angiography (6 cases): Performance increases of renal kidney shadow Shadow and the relationship between the neighboring organs, its boundaries clear and identified; CT scan (30 cases): the performance of the majority of the size of the renal low-density areas, ranging from thin-walled circular; B-mode ultrasonography (47 cases) showed a circular echo-free renal multiple classes of liquid dark area .

结果 成人多囊肾的主要影像学征象：腹部平片(45 例)显示肾影呈分叶状增大；囊壁钙化(14例)；多囊肾合并肾钙乳(8例)；肾盂造影(61例)，表现为肾盂、肾盏相互分离、变形、拉长；腹膜后充气造影(6例)：表现为肾影增大肾影与邻近器官之间的关系，其界限清晰可辨；CT扫描(30例)：表现为肾内多数大小不等的薄壁圆形低密度区；B型超声(47例)表现为肾内多个类圆形无回声的液性暗区。结论影像学检查有助于提高多囊肾的诊断的准确性。

The tumor is sessile, polypoid, or castlike and is characterized by the presence of innumerable papillary frondlike infoldings comprised of proliferations of columnar epithelial cells around the slender fibrovascular stalks that are supported by the connective tissue of the lamina propria.1 Occasionally, tumor spreads superficially along a variable length of the bile duct.

该肿瘤是无蒂、乳头样或脱落物样的，以及肿瘤表面特征性地存在无数乳头样叶状内折叠，这些乳头是由围绕纤细的以管腔的结缔组织为支撑的纤维血管茎增殖的柱状上皮细胞构成。肿瘤偶尔也会沿不同长度在胆管表面蔓延。

Long branch is rufous, show "" the glyph bends, smooth, have stipular thorn or not apparent; Short branch is born in the each other on the long branch of biennial above; Fall off sexual rod is finer, without bud, bunch is born on short branch, after autumn and foliaceous all fall.

长枝红褐色，呈&之&字形弯曲，光滑，有托叶刺或不明显；短枝在二年生以上的长枝上互生；脱落性小枝较纤细，无芽，簇生于短枝上，秋后与叶俱落。

Biological characteristics of the pathogen and the resistance of 13 cultivars of tea plant to tea brown blight were studied by means of natural infection in the field and artificial inoculation in vitro. Resistant cultivars and susceptible cultivars of tea plant were divided. And the resistance mechanism was researched tentatively. The findings are as follows: 1 Some biological characteristics of the pathogenic fungus The experiment result showed: the optimum temperature for the growth of fungus mycelium was from 24 to 27℃, the optimum temperature for sporulation ranged 22 to 30℃. Treated at 54℃ in 10 minutes, the spores didn't germinate. The optimum pH for the growth of the mycelium was 5.1～5.9, the optimum pH for sporulation ranged 5.0～6.0. Light had no much effect on the growth of fungus mycelium, but had much effect on the reproduction of the spore.

首先，研究了茶云纹叶枯病病菌的生物学特性；其次，通过田间抗性调查和室内人工接种鉴定，对 13 个茶树品种进行了抗病性鉴定；第三，在前人研究的基础上，对茶树抗病机理作了更深入的研究，结果发现： 1 病原菌的生物学特性病原菌的分生孢子萌发的最适温度范围为 24～27℃，菌丝生长的最适温度范围为 22～30℃；致死温度为 55℃；菌丝生长的最适 pH 范围为 5.1～5.9，孢子萌发的最适 pH 范围是 5.0～6.0；光照对病菌生长速度及分生孢子萌发影响不大，但对其产孢的影响很大，特别是有光照与无光照处理之间差异显著，光照有利于分生孢子的形成。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
