用显微镜检查

Thin leaf section were prepared from fresh tissues of YS-lnfected and healthy citrus plants, when observed under a fluorescence microscope (Type, Olympus AH-FL-2), a yellow fluorescence was distinctly observed in the YS-infected phloem tissues and not in the phloem tissuses of healthy plants and of those infected with tristeza, exocortis, canker, scab, greasy...

将健叶和黄龙病叶叶柄用保险刀片徒手切片，在透射式荧光显微镜下检查，可看到健叶叶柄的木质部导管细胞壁发黄色荧光，韧皮纤维细胞发绿色荧光，而病叶叶柄韧皮部中有1～多个鲜明的黄色或黄绿色荧光团块。这种特异性的荧光，在健叶柄韧皮部中是没有的，其它由病毒、类病毒、细菌、真菌等病原引起的病叶柄韧皮部中亦没有此种特异性荧光。

http：//www.44dx.com 目的观察维拉帕米(verapamil，ver)对眼后节穿通伤增生性玻璃体视网膜病变(proliferative vitreoretinopathy，pvr)的影响。方法64只青紫蓝兔，每只兔任选其中一只眼制备外伤性pvr模型后随机分为两组，治疗组在模型制备后立即每日结膜下注射2.5 mg/ml的ver0.5ml，对照组则每日结膜下注射生理盐水0.5ml，共21天。模型制备后7天内每天用裂隙灯显微镜及间接立体检眼镜观察伤口、角膜、前房及眼底情况，此后每周第3，7天各检查1次。伤后第35天时常规摘除模型制备眼作光镜观察。

By examining a leaf with a scanning electron microscope, both micrometer scale bumps as well as nanometer scale hair-like structures are seen covering the surface of the leaf.

通过用电子显微镜对叶子进行扫描检查，采用块状的千分尺测量和类似头发结构的毫微米测量都能观察叶子表面覆盖的东西。

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。
