人工差异

It is first found that there is an important difference in order-disorder of crystalline structure between the artificial pitchblende and natural pitchblende. Unlike natural pitchblende in which uraninite nanocrystals arrange in order, the artificial pitchblende only contains disorderly uraninite nanocrystals.

在国内、外首次发现此类人工合成沥青铀矿和天然沥青铀矿在晶体结构的有序—无序上存在重大差异：天然沥青铀矿中的纳米级晶质铀矿为有序排列，而人工合成沥青铀矿中的纳米级晶质铀矿则为无序排列。

A new method of disease area mensuration and the percentage of diseases area of tea leaves with computer has been established by using Photoshop software to scan many leaves at the same time, and the further investigation also has been fulfilled. The results showed that when scanned with resolution 150 dpi,there were be short time to scanning and less disk space beenoccupied, and the effect as same as scanned with high -resolution. The results of disease area mensuration and percentage of diseases area of tea leaves using the new method also as same as the results using artificial mensuration, and the efficiency of the new method is much higher than the efficiency of artificial method.

摘 要：建立了通过对茶树叶片进行扫描，利用Photoshop软件同时获得多张叶片及其受害部位的像素值，从而快速计算茶树叶片受害面积以及受害面积百分率的测定方法，并对此方法进行了系统的研究，结果表明：扫描分辨率为150dpi时，扫描时间和存储占用空间较优，测定效果和高分辨率扫描效果基本一致，该方法测定结果与人工测定结果无显著差异，其效率远远高于人工测定。

The results indicated:During the course of vegetation natural recovery, there are different stage of secondary sere at different degree of degraded lands, that is secondary herbosa; secondary scrub; masson pine coniferous forest; conifer and broad-leaved mixed forest; every green broad-leaved forest.

本项研究从比较生态学入手，分析了千岛湖地区退化森林生态系统不同植被恢复措施，即：自然恢复、人工促进自然恢复和人工恢复措施下的群落生态变化，比较了不同措施之间的生态响应差异，研究结果表明：①在植被自然恢复过程中，由于生态系统退化程度的不同，存在草灌丛、灌丛、马尾松林、混交林和常绿阔叶林整个演替序列。

There is no obvious difference between rice stem borer reared by three kinds of artificial diet and that by fresh rice stem.

人工饲料配方Ⅰ、配方Ⅱ和配方Ⅲ连续3代饲养的二化螟与新鲜水稻茎杆饲养的3代二化螟在整体上没有显著差异，是3种比较理想的二化螟人工饲料。

Those parent abalones of wild or artificial selection with good economic characters must be chosen in order to avoid close breeding.. Correct breeding techniques must be adopted to obtain excellent germ cells and larvae. The survival rate and disease resistance of juvenile abalone can be remarkably increasedonce the further selecting and culturing are carried out. The rejuvenation is realized once a good breeding condition for the young and parent abalones is created, the adverse culturing condition and technical maloperation are reduced or eliminated. The survival rate of the breeding and young abalonesincrease about 28.9%-31.2%, the survival rate of the grown abalones is high up to 85%-90%.

通过挑选经济性状好的台湾九孔鲍和人工选育的九孔鲍亲体进行繁殖，避免近亲繁殖，选优除劣，达到正本清源的目的；采用正确的繁殖技术，获得优良的受精卵和幼虫，通过对幼虫进一步选优和培育，使附板后的幼鲍成活率及抗病力得到明显提高；为九孔鲍的苗种和亲本培育创造良好的养殖生态条件，减少和消除了不利的养殖环境和操作技术，达到品种复壮的目的；阐述了野生鲍、复壮鲍、退化鲍三个不同类群的免疫机能具有显著的差异，复壮后的九孔鲍，其免疫机能基本达到了野生鲍的水平；人工育苗和幼鲍的成活率提高了28.9%-31.2%；成鲍的养殖成活率高达85%-90%以上。

And, there was significant difference between breast feeding group and artificial feeding group with breast feeding group and mixture feeding group.

结果 母乳喂养婴儿感染性疾病的发生率明显低于人工喂养组和混合喂养组，且母乳喂养组与人工喂养组、母乳喂养组与混合喂养组两组间的差异有显著性。

The conditions on infectious disease of infants were analysed. RESULTS The incidence on infections disease of infants in breast feeding group was lower than that in artificial feeding group and mixture feeding group.

结果 母乳喂养婴儿感染性疾病的发生率明显低于人工喂养组和混合喂养组，且母乳喂养组与人工喂养组、母乳喂养组与混合喂养组两组间的差异有显著性。

In the 37 herbaceous species identified, only 18, 25, 20, 25 and l7species were present in the PS, PA, PD, HR and CK forests, respectively. For herbages, Stipa bungeana, Arthraxon hispidus, Potentilla multifida and Thymus mongolicus were common in the five plantations. The average coverage, height and biomass of herbages in five artificial forests were different obviously, but community biodiversity was similar.

结果表明：5种人工乔灌林下共有37种草本植物，各人工林林下物种组成数量在17~25之间变化，其中以杏树林最多；5种人工林下草本层平均盖度、平均高度、平均生物量存在较大差异，但多样性指数相差不显著。

Results There was no significant difference in hearing results between the bioceramic and titanium ossicular protheses in regard to the management of mastoid lesion, the methods of ossiculoplasty.
