Biological characteristics of Curvularia lunataBoedijn had been preliminarily studied. Optimal mediums for pathogen growth were PSA,PDA and OMA.For mycelia growth,sporulation and conidial germination of pathogen,optimal temperature was 25～30℃,and pH 5～9.Among the tested carbon and nitrogen resources,sucrose,glucose,carbamide,sodium nitrate,etc were beneficial for mycelia growth and sporulation.The conidia germination is strict in RH requirement:Conidia can germinate at RH 81%～98%,or have 100% germin...

香蕉大灰斑病菌适合生长的培养基有PSA、PDA和OMA；菌落生长、产孢和孢子萌发最适宜的温度为25～30℃，pH 5～9；在碳源和氮源中，蔗糖、葡萄糖、尿素、磷酸氢二氨和硝酸钠有利于病菌生长和产孢；分生孢子萌发对湿度有严格的要求，RH≥80%以上分生孢子萌发，随湿度增加萌发率增高；光照对菌丝体无显著影响，光暗交替有利于孢子的形成；孢子致死温度为55℃(10min)。

Leaves opposite , very rarely stipulate, petiolate, entire, leathery to papery, usually glabrous; secondary veins usually prominent, numerous to few, oblique to perpendicular to midvein; tertiary veins reticulate, with adaxial brownish transvenous resin canals and abaxial linear or intervenous translucent glands; petiole often with basal liguliform appendage.

Leaves opposite or distal ones in whorls of 3 or 4, sessile or petiole to 5 mm, villous; leaf blade long ovate to ovate-oblong, 2--5 X 0.7--1.5 cm, pubescent on both surfaces, pinnatipartite to pinnatisect; segments 6--10 pairs, linear to linear-oblong, incised-dentate.

叶对生或上部的3轮生或4，对5毫米，具长柔毛的无梗或叶柄；叶片长卵形到卵状长圆形，2-5 X 0.7-1.5厘米，两面被短柔毛，对羽状全裂的羽状深裂；裂片6-10 对，线形的到线形长圆形，锐裂具牙齿。

结果：6种麻黄属植物之间气孔密度、茎、叶表面特征存在不同程度的差异；气孔表现出典型旱生植物的特征，略下陷，气孔保卫细胞被厚的角质层覆盖，并形成突起状角质唇状物；气孔大小、形状在种之间无明显区别；叶表面、茎表面气孔均属于无规则型，但形状明显不同，前者主要呈长方形或六边形，后者为窄条形或哑铃形。

Result:The stomatic density and characteristic of leaf epidermis and stem epidermis in six Ephedra species was differenc,there were no obvious morphological differences in stoma shape and size.

结果：6种麻黄属植物之间气孔密度、茎、叶表面特征存在不同程度的差异；气孔表现出典型旱生植物的特征，略下陷，气孔保卫细胞被厚的角质层覆盖，并形成突起状角质唇状物；气孔大小、形状在种之间无明显区别；叶表面、茎表面气孔均属于无规则型，但形状明显不同，前者主要呈长方形或六边形，后者为窄条形或哑铃形。

Results Medical students' knowledge level of AIDS prevention was higher than those of normal student. No significant difference in understanding three transmission mutes of AIDS was found between medical students and normal students. There were significant difference between the two groups of students in some other transmission proutes, attitude to AIDS and sexual conception.

结果 医学生对艾滋病相关知识的了解程度高于师范生；医学生和师范生知晓艾滋病的三大传播途径的比例差别无统计学意义，但对某些传播、非传播途径的认识差异有统计学意义；两者在对待艾滋病的态度、性观念的方面差异也有统计学意义。

Inflorescence branching or unbranched, branches bearing terminal umbels; bracts usually absent; rays 4–40, unequal, erect to ascending in flower, spreading widely and lengthening in fruit; bracteoles 1–4, linear-lanceolate, unequal; umbellules very few flowered, 2–3(–5)-flowered; pedicels extremely unequal.

花序分枝或者不分枝，分枝生顶生伞形花序；苞片通常无；伞辐4-40，不等长，直立到上升的在花中，平展的宽和变长的在果期；小苞片1-4，线状披针形，不相等；小伞形花序的非常少的花，2-3(-5)花；花梗极其不相等。

The results showed that the plant had the character of damp-inhabiting, the cutical on the epidermis of stem and leaf is rather thin but without wax-layer, its stomata protrude clearly on the lower surface of leaf, the rate of palisade parenchyma and spongy parenchyma is rather low and the cortex is well developed in root.

结果表明蓝靛果具有明显的湿生特征：茎、叶表皮的角质层薄，无蜡被；叶片上表皮细胞甚大，无气孔，下表皮细胞小，气孔明显突起；叶脉导管直径小，壁薄；叶肉栅栏组织/海绵组织小；根的皮层发达，富细胞间隙。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
