研究产量差异大的高产菌株和低产菌株的各种生物学特性，发现通过油脂水解平板的颜色以及发酵液的酸价，与菌株的发酵单位有直接相关性，从而建立了快速筛选模型。

Tiller is one of three major determinant factors of rice yield, an important yield trait, and a key parameter in ideal rice pattering.

分蘖是产量构成因子的三要素之一，是重要的农艺性状，也是理想株型构建的重要参数。

The markets are just as kind to other euro-zone spendthrifts. Government bonds from Greece (deficit last year, 5.2% of GDP; debt, 108%; but GDP growth, healthy) yield about the same as Italy's. Those from Portugal (deficit, 6%; debt, 63%; growth, perkier this year after a feeble run) yield ten basis points less.

希腊（去年的赤字占到该国GDP的5.2%，债务占到GDP的108%，但是该国GDP的增长健康）公债收益率和意大利同种公债的收益率相同，而比葡萄牙（赤字占到该国GDP的6%，债务占到GDP的63%，在经历了缓慢的增长后，今年该国的经济增长会更有强劲）低10个基点。

The yield was sensitive to water supply during flowering and podding stage, in which the sensitivity was found podding stage （ R3 - R5 ）〉 flowering stage （R 1 - R3 ）〉 vegetative stage （V2 - R1 ）〉 the contribution of water supply to the yield formation was more central than potassium fertilizer application in light of controlling soil water at the same growth stage.

大豆对水分较为敏感的时期是开花期和结荚期，各时期敏感程度表现为结荚期〉花期〉营养生长期；同一生育时期控水下水分对大豆产量的影响要高于钾肥；旱涝都将影响大豆籽粒产量的形成，但干旱引起的减产程度要大于涝害。

The result showed that there were significant effects of different sowing stage on the growth stage, the sprouting of axillary bud and yield of ratooning rice, rice sowed on March 31 was best, and the grain yield was highest that sowed on April 11 was worse, but it could mature normally, that sowed on April 19 could not reach full heading stage before safely full earing date, so some panicles could not be heading or could not mature normally.

结果表明：不同播种期对再生稻生育期、腋芽萌发和产量均有明显影响，以3月31日播种的腋芽萌发好，再生季产量高，4月11日播种的腋芽萌发较差，但能正常成熟，4月19日播种的腋芽萌发差且不能在安全期内齐穗，导致部分穗子不能抽穗或能抽穗但不能正常成熟。

The result shows: in 0~360 kg/hm^2 fertilizer can improve the plant height, dry matter accumulation of maize, nitrogen accumulation, root vigor, leaf nitrate reeducates activity, chlorophyll content and yield, meanwhile the leaves' nitrate reeducates activity, dry matter accumulation and the final output of wheat, root activity and other indicators were significantly correlated; Cultivating under the same conditions and dropping the fertilizer amount from 360 kg/hm^2 to 315 kg/hm^2, the dry matter accumulation will be increased, the roots vigor and leaf nitrate reeducates activity will be strengthened, but the yield are not obviously different in the same treatment.

结果表明：在0~360kg/hm^2的施肥范围内，肥料能显著增加玉米植株的株高、干物质积累盆、叶绿素含量和籽粒产量，提高根系活力、叶片硝酸还原酶活性；同时硝酸还原酶活性、干物质积累量、根系活力和叶绿素含量等指标与玉米最终产量呈显著正相关；在相同的栽培条件下，将施肥量从360kg/hm^2降至315kg/hm^2，植株的于物质积累量增加、根系活力、叶片硝酸还原酶活性增强，但处理间籽粒产量无显著差异。

Based on present researches,by means of modern measurement and analysis techniques,systemic laboratory experiments,field investigations and through theory researches were conducted.And following are the major points and achievements presented in this dissertation:①The micro-convexity on fracture plane was studied.Analyzing and comparing the static attribute and dynamic variation of natural fracture with the artificial,untreated fracture,artificial and scabbled fracture as well,making out the criteria that artificial and scabbled fracture simulate natural fracture.②We take the effect of all the three primary stresses and stress invariant into account in the Lade-dbl yield criterion,which can preferably reflect all the yield and destruction characteristic of the rock material.

结合裂缝性储层应力敏感性研究现状，利用现代化测试手段，通过系列的室内实验以及深入的理论探讨，本文取得的研究成果包括以下几个方面：①从裂缝面上的微凸体入手，分析和对比了天然裂缝、人工但未经过处理的裂缝，以及经过粗化处理以后的人工裂缝的静态特征和动态变化，指出了经过粗化处理以后的人工裂缝模拟天然裂缝的依据；②Lade双曲服面屈服准则考虑了所有三个主应力或应力不变量对屈服与破坏的影响，能够较好的反应岩石材料的所有屈服和破坏特性。
