The morphology of M2 and M3 was observed in hothouse and mutants on cotyledon and root of seedling, or embryo of seed were identified. The result showed that there were 8 types of mutative treats on cotyledon, including light-yellow cotyledon, yellowish cotyledon, trump-shaped cotyledon, multilobed cotyledon, non-cotyledon, single-cotyledon, tricotyledon and quadrcotyledon.

M_2和M_3的水培和形态学观察的结果发现，子叶性状出现浅色、黄化、喇叭形、多耳突、无子叶、单子叶、三子叶、四子叶等8种变异类型；根系性状出现短小根、发达根、无侧根和弱向地性等4种变异类型；种胚性状中发现了多胚变异。

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。

In purplish soil, the number of dominant microbial populations in the rhizosphere was greater than in the other two soils, and the population diversities of bacteria and actinomycetes were even greater and more constant, suggesting that the community structures of microorganisms in neutral purplish soil were more reasonable than in both yellow earth and yellow rendzina, which was probably related to the low incidence of tobacco bacterial wilt in the neutral purplish soil.

烤烟根际微生物的种群多样性及其变化在不同土壤中表现也不一样，相对于黄壤和黄色石灰土，在中性紫色土中，根际微生物的优势种群数目较多，根际细菌和放线菌种群更具多样性，而且较稳定，表明其群落结构更为合理，这可能与中性紫色土上的烟草青枯病发生率较低有一定关系。

The epineurial vessels run along the nerves length and gave off branches, distributing along nerve bundle, to enter into endoneurium. The endoneurium contained only capillaries. Arteriolovenular anastomoses were few in trigeminal nerve root. The distribution of microvessels in trigeminal nerve root was uneven. The number of microvessels in the medial portion was less than that of the distant.

神经外膜血管沿神经根径向走行，沿途再发侧支斜行或横行入神经束之间，顺神经根束分布，并发侧支进入神经内膜；半月结内微血管围绕神经节细胞分布；三叉神经根内的微血管配布不均，其近侧端微血管数量较少，远侧端微血管数量较多。

Breed can be used sow law, cuttage law and Qiegenfa to breed, sow ℃ of 20-25 of gemmiparous comfortable Wen Wei to control, spring, summer, Qiu Jun but, left and right sides of a month after sowing is gemmiparous, sow although the law is OK short time acquires more plant amount, but from the time that sows to blossom longer, still be much commonly so with cuttage breed is given priority to, cuttage with spring, summer two Ji Wei is comfortable period, insert with terminal bud for beautiful, cuttage sends a root extremely easily, cuttage hind can become a young plant about 4 weeks.

繁殖可利用播种法。扦插法及切根法繁殖，播种发芽适温为20-25℃左右，春。夏。秋均可，播种后约1个月左右发芽，播种法虽然可以短时间获得较多的植株数量，但是从播种到开花的时间较长，所以一般还是多以扦插繁殖为主，扦插以春。夏两季为适期，以顶芽插为佳，扦插极轻易发根，扦插后约4周即可成苗。

The focus of this paper is to make an outline of the first part of the book, 'pistémologie analytique ou descriptive'', in contrast with Thomas Aquinas's original text.

本文的重点在於根据汪斯坦博根《知识论》的第一部分「分析或描写的知识论」，加以浓缩其要点，并试图就部分重要论点和多玛斯的原始文献加以比对，以彰显汪斯坦博根与多玛斯在知识理论上前后辉映的旨趣。

Results The clinical observation of 180 patients with entirely developed root apex of acute and chronic apical periodontitis shown that there was no significant difference comparing erythromycin ethylsuccinate-metronidazole-CP with FC in root canal sterilization, therefore, the irritability and poisonousness of the paste can be reduced by using erythromycin ethylsuccinate-metronidazole-CP instead of FC.

为了清除髓腔病源刺激物，促进根尖病变愈合，目前国内大多用甲醛甲酚进行根管消毒。甲醛甲酚属化学制剂，虽具有强烈的杀菌作用，但亦具有刺激性、毒性和抗原性等，而琥珀酸红霉素和甲硝唑在临床上已被证明对厌氧菌有明显疗效，对于根管内的消毒杀菌作用如何，研究报道不多。

Methods 96teeth with pulpitis or periapical periodontitis were instrumented by handling ProTaper rotary instruments using step-down technique,and by K files using step-back technique for control.All teeth were obturated with lateral condensation methods.The efficiency of preparation was analyzed with ra-diographs before and after operation.

选取患有牙髓炎和根尖周炎的后牙96例，随机分成试验组和对照组各48例，试验组用手用ProTaper多锥度镍钛旋转器械逐步伸入法预备根管，对照组用K锉，逐步后退法预备根管，两组均用侧向加压充填法充填根管，根据治疗前后的X线片，评价后牙根管预备效果。

Inwheat intercropped with soybean not only N situation could be improved butalso P situation could be.2In intercropping,the pH of soybean rhizospherewas decreased by increasing the R-Apase activity,which could decelerate thetransforming and fixing P fertilizer.3In both monoculture and intercroppingsystem,the soil pH of rhizosphere was affected by cropping system at two Plevel which only 0.1-4mm distance from the root surface,but the effect of S-Apase activity in the rhizospher soil by cropping system was less than3mm.In effect,the rhizosphere P was really available nutrient,and applyingP to rhizosphere was effective ways to reduce the P nutrient competition.4Inwheat/soybean intercropping,the peak stage of reduction ability of roots wasthe same as that of the root growth,so that the time compensation appearedin intensity of nutrient absorption.

间套作大豆、小麦、玉米根系Apase的差异又反映出大豆利用土壤磷的潜在能力最大，而玉米最小，可见禾谷类的小麦与大豆间套后不但能改善小麦的氮素营养状况还使磷素营养也得以好转。2）间套大豆根际pH值的下降，导致磷肥施入土壤后形成〓-P的比例显著提高，转化成〓-P等难溶性磷减少，说明间套的大豆能减缓肥料磷在土壤中的转化和固定，减少磷素向无效化方向转化。3）复合群体根际土壤pH值的影响一般只发生在0.1-4mm的根际微区，而土壤磷酸酶的影响供磷与否在距根表3mm以外都无多大差异，说明根际磷才是真正有效磷，根际施磷是解决磷素竞争的有效途径。4）。
