有根

Long ago there was a boy with bad temper.his father gave him a bag of nails and told him to knock in a nail into the fense around the yard when he got angry or quarreled with others.the first day the boy drove 37 nails into the fense.a couple of days later ,he learned to control himself so that he drove fewer and fewer nails as days past.he found it that it was easier to control his temper than knock in a nail.finally he nailed not even a nail a day ,he was so happy to tell his father.

从前，有一个脾气很坏的男孩。他的爸爸给了他一袋钉子，告诉他，每次发脾气或者跟人吵架的时候，就在院子的篱笆上钉一根。第一天，男孩钉了37根钉子。后面的几天他学会了控制自己的脾气，每天钉的钉子也逐渐减少了。他发现，控制自己的脾气，实际上比钉钉子要容易的多。终于有一天，他一根钉子都没有钉，他高兴的把这件事告诉了爸爸。

For instance, it is usually accepted that there will be multiple ''root'' or ''top-level'' certificate authorities in a global PKI, not just one ''root,'' although in a local PKI there may be only one root.

例如，通常可以接受在全球性的PKI中有多个"根"或"顶级"证书授权中心，而非只是一个"根"，尽管在本地PKI中只能有一个根。

Neurological status on admission was as follows: spinal cord and nerve root lesion in 5 cases, nerve root lesion alone in 5 cases and neurologically intact in 2 cases.

The results showed:among the 7 isolates, five isolates of HY3、GY1－3、ZJ1－1、HP1、FC3 had same colony shape, irregular shape, liquidlike, slimy, opacity with smooth surface;the other two isolates had same shape, irregular shape, dry, opacity with coarse surface. By inoculating eucalyptus with the 7 isolates, the plants were infected apparently, and the young plants of eucalyptus in control experiment with tap water were not infected. By cultivating eucalyptus cuttings with the bacterial suspensions without EPS, the incidence of disease was very distinct,but compared with the former bacteria suspension,the incidence of disease has decreased at different degrees. By screening out two isolates of strong pathogenicity and two isolates of weak pathogenicity from the 7 isolates,making the bacterial suspensions with them to inoculate the young plants of eucalyptus, two treatments of cutlings and ramets with rats were set with 5 repetitions in every treatment, the results of data analysis showed: for the cutlings, the bacterial contents in upper and middle parts、upper and lower had significant difference;for ramets with roots, the bacterial contents in upper, middle parts, lower had significant difference between each other; For both the cutlings and ramets with roof, the bacterial contents in xylem and phloem had significant difference. The interaction between vertical and horizontal parts for the bacterial content had significant difference. For the two isolates of HY3 and 93B which were screened out at last,their activities of the cellulase were: 1.955ug/ and 1.288ug/ respectively, and had significant difference; the activities of pectase were: 1.325 ug/and 1.24ug/ respectively, and had no significant difference. The content of EPS extracted from the two isolates of HY3 and 93B was very different: 7.08x10-8ug/cell and 5.17x10-8ug/cell.

结果显示：7个菌株中，其中5个菌株HY3、GY1－3、ZJ1－1、HP1、FC3的菌落形态相同：不规则形状、流体、粘性、不透明、表面光滑；另外2个菌株93B、GN1菌落形态相同：不规则形状、干燥、不透明、表面粗糙；用7个菌株接种剪根桉树苗，发病情况非常明显，而自来水对照实验中桉树苗却不发病；无EPS菌悬液培养桉树剪根苗，发病率也很明显，但是相比原菌液，则发病率有不同程度的下降；从7个菌株中间筛选出来2个强致病性菌株和2个弱致病性菌株，用它们配制菌悬液培养桉树苗，设置剪根和不剪根两个处理，每个处理设置五个重复，数据分析结果显示：对于剪根苗，上部和中部、上部和下部的含菌量有显著的差异，中部和下部含菌量差异不显著；带根苗，上部、中部、下部含菌量彼此之间差异显著；不管是剪根苗还是带根苗，木质部和韧皮部含菌量之间的差异都非常显著；上中下与木韧交互作用中，含菌量差异非常显著；最后筛选出来的强弱2个菌株HY3和93B，它们的纤维素酶活性分别为：1.955ug/和1.288ug/，具有显著的差别；果胶酶的活性分别为：1.325 ug/和1.24ug/，没有显著的差别，而且HY3和93B两个菌株细胞分泌的胞外多糖的含量差异很显著，分别为：7.08×10-8ug/cell和5.17×10-8ug/cell。

" "Well," I says,"if it's in the regulations, and he's got to have it, all right, let him have it; because I don't wish to go back on no regulations; but there's one thing, Tom Sawyer -- if we go to tearing up our sheets to make Jim a rope ladder, we're going to get into trouble with Aunt Sally, just as sure as you're born.

" "好吧，"我说，"如果这是规矩，那他就准得有一根绳梯。那就让他有一根吧。因为我并不退回到不按规矩办事的地步，不过嘛，还有一件事呢，汤姆·索亚――要是得把我们的衬衫给撕下来，给杰姆搞一根绳梯，那萨莉姨妈肯定会找我们算帐，这是可以断得定的。

Tapirs have 14 toes altogether. Each of a tapir's front feet has four toes, and each of its back feet has three toes.

貘一共有十四根脚趾，每只前脚都有四根脚趾，后脚也各有三根脚趾。

RESULTS: The mild traction group showed angulus anterior individual neuron slightly engorged, neuron and nerve fiber morphous was normal essentially; individual substantia alba demyelinates in fragmentis; medullary sheath and auxiliary fibers of nerve root were hydropsia slightly without conspicuous myelinolysis. The moderate traction group demonstrated myelinolysis change in the spinal cord, and neurofibras lined up chaos, auxiliary fibers disaggregated, neuron dropsy, tigroid body disappeared with karyopycnosis and anachromasis in neurons; nerve root showed myelinolysis. The severe traction group displayed a great demyelination region; anterior motor neurons with karyopycnosis and anachromasis; myelinated nerve fiber of nerve root shrinked, decreased in number, with severe demyelination changes.

METHODS:Fifty two permanent maxillary first molars,which were diagnosed as pulpitis and periapical periodontitis clini cally,were selected.The pulp chamber floors were examined and detected to locate the mesiolingual canals(MB2) by naked eyes and SOM respectively.

由于其近颊根通常有近中颊和近中舌(MB2 ) 2个根管，而其近中舌根管细小且根管口常较为隐蔽，因此，Weine认为上颌第一恒磨牙根管治疗失败的一个主要原因是治疗中遗漏了MB2根管。

Results: group A( diskectomy, 160 cases) were followed up and excellent: short-term 90%,in the near future 88%, long-term 84%;36 cases were accepted second operation during 0.5 year to 5 year and 28 cases had nerve root canal stenosis.

The resulted that there was an obvious rhizosphere effect in all growing years of Caranaga microphylla plantation. The pH value of rhizosphere soil was lower than those of near rhizoshphere soil at different growing years. The content of organic matter, total N and available K in rhizosphere soil were all higher than those in near rhizoshphere soil, but the content of Olsen-P in 5-age plantation was remarkably deficient in rhizosphere soil.

对不同生长年限的小叶锦鸡儿人工灌丛根际土壤变化规律研究表明，根际土的pH均小于根外土：土壤有机质、全氮、速效钾在根际土中均有一定程度的富集现象；而5年生的小叶锦鸡儿根际土的有效磷含量出现了亏缺。

I am accused of being overreligious," she said in her quiet, frank manner,"but that does not prevent me thinking the children very cruel who obstinately commit such suicide.""
