Result Wild castor preformed better in halophilism than that of cultivar castor Zibi 6 under the NaCl treatment. One of the salt tolerant mechanisms of castor is to improve K(superscript +) uptake and transport to overground portion, thus to maintain K(superscript +)/Na(superscript +) homeostasis in leaves; on the other hand, the high stability of Photoreaction System Ⅱ plays a key role in maintaining the leaf photosynthetic rate under salt stress.

结果］野生蓖麻较栽培蓖麻具更明显的喜盐特性；蓖麻的耐盐机制在于促进K的吸收和向地上部的运输，进而维持叶片的K/Na平衡；通过维持光系统Ⅱ的稳定性进而维持盐胁迫下叶片的光合速率。

The preformed dental crowns also include a hardenable composition that has sufficient malleability such that the side-generic external shape can be formed into, e.g., a left-side specific or right-side specific adjusted external shape.

In addition, ioding was found to be an efficient catalyst for the imino Diels-Alder reaction of N-arylimine and enol ethers and the reaction provided tertrahydroqinolines in good yields. One pot synthesis of tetrahydroqinolines from aldehyde, aniline and enol ethers was also achieved using iodine as the catalyst. The chemical yield of the"one pot"reaction was comparable with that obtained using preformed N-arylimine.

此外我们也发现碘能够有效地催化N-芳基亚胺与烯醇醚的Diels-Alder反应，以很高的化学收率得到了四氢喹啉衍生物，并且发现碘也能够直接催化芳香醛、苯胺、烯醇醚的三组分&一锅&反应，获得的化学产率与使用预制的N-芳基亚胺相当。

Although the qualitative evaluation of cell images can be preformed visually, the manual interpretation of them is a tedious and time-consuming task. Moreover, irreproducible and subjective conclusions are usually drawn. Automatic image analysis is able to overcome these shortcomings.

通过观察可以定性地评估细胞图像，然而，人工地从这些图像获取有用信息则是一项非常繁重和耗时的任务，而且结论往往是不可重复、主观的，自动图像分析则能够弥补这些不足。
