一個物種的滅絕是與其受生物因子和非生物因子的威脅程度相關的.隨著物種的加速絕滅,保護生物多樣性受到廣泛地關注.保護生物多樣性的最有效的生物技術之一是建立種子基因庫,進行遷地保護.種子庫理想的貯藏條件主要取決于種子含水量、貯藏環境(如溫度和濕度)和貯存種子的容器.進行種子貯藏,了解種子生命力和活力的影響因子的作用機理是十分重要和必要的.除了種子自身的生理特徵外,種子的貯藏壽命與種子成熟度、收獲技術、加工處理方法也是息息相關的.即使在最適的庫存條件下,種子也會隨時間發生劣變.因此,必須根據種子特定的貯藏行為,加以考慮影響種子存活的3個主要方面(貯藏環境、貯藏期和植物種類)而選擇有效的貯藏方案.本文試圖討論種子貯藏生理的幾個重要方面及其需解決的技術問題,以便更好地通過種子基因庫,長期有效地保存植物種質資源It is not many scholars to clearly prove the opinion of shifting the burden of proof, on the contrary the contradictory scholars are more prominent, for example the vice professor of southwest politics and law university, chengang, wuyue who translates and introduces the burden of proof of germany, because them there are more and more people support the opposite opinion, while in the draft of " civil evidence code ", the traditional idea win, in this draft the legislator abides by the present justice and our country ' s native circumstance, they made an scientific choice, of course, the burden of proof will directly influence the party " s possibility of losing the lawsuit, while the regulation of shifting the burden of proof increases the plaintiff ' s opportunity to win a lawsuit. to explain what is the shifting of burden of proof, the paper use the civil law as the example to point out the " reverse " is not entirly relieve the plaintiff s obligation of producing evidence, but in certain extent and in certain range make the defendant bear the burden of producing those proofs from the reverse way, which are originally beard by the plaintiff. in the three proceeding law, shifting the burden of proof have some differences, but the interior spirits are coincident - for the values of social justice and the legal reason
論證舉證責任倒置的學者觀點明確並且論證十分充分的不多,相反卻是對此著書立說予以反駁的學者較為突出,如西南政法大學的副教授陳則博士,翻譯並介紹德國證明責任學說的吳越先生均是目前國內對舉證責任倒置持否定態度的代表人物,由於他們的推動使得國內持此說的人越來越多,但在《民事證據法(草案) 》的擬定過程中,並未采責任倒置的地位,這樣的立法選擇是建立在對我國法律實現的本土環境客觀認識的基礎上的科學選擇,誠然,舉證責任的分配直接影響到當事人在訴訟中的敗訴風險,而「倒置」規則的設計,則在此問題上增加了原告勝訴的籌碼,在理解何為舉證責任倒置時,本文著重以民事法為主線,指出這種「倒置」並非全部免除原告的證明責任,而是在一定范圍與一定程度上將通常應由原告負擔的舉證責任轉由被告從反方面承擔,舉證責任倒置在三大訴訟法中所體現的具體情形有所差異,但它們的內在精神是一致的?法律的理性與社會公平價值,在民事訴訟中舉證責任倒置的情形,一般總是將其局限於特殊侵權情形,而忽略了民事合同違約責任的訴訟中的原告也無須對被告應承擔違約責任的所有要件,對被告主觀上的過錯實行推定,若被告予以否定則應對其無過錯的證據舉證,在設置舉證責任倒置的規則時,從各國的立法經驗與法的內在價值要求可以總結出以下幾個原則:程序法與實體法結合原則,公平原則,訴訟經濟原則,保護弱者原則等,基於此完善舉證責任倒置的規則時首先應肯定舉證責任倒置的概念,其次立法應避免求大求全,再次要配合實體法的發展,最後還可以在司法領域嘗試判例的指導意義。This text completely and systematically studies the status and the development of the pyrolysis and the fluidization of biomass, which distill the bio - oil in the domestic and international area, as well as the existing problems. this thesis primarily include following aspects : ( l ), by experimenting and measuring the energy ( heat value ) and the content of c, h, n chemical element of right 20 kinds of common biomass, on the base of the experimental result, and respectively established the biomass energy predict experiment formula with the element of h and c is from change, and passed the ro. os examination, which provides the basis and convenience for flash pyrolysis fluidization device energy to convert the rate to compute with biomass energy utilization calculation ; ( 2 ), proceeded the tg and dtg experimentation equal velocity ( 10 ? / min, 20 ? / min, 40 ? / min, 60 ? / min ) heating and constant temperature heating by studying on eight kinds of biomass samples, according to the experimental data and arrhenius formula, we established the dynamics model of pyrolysis of, then, using the goast - redfern and p function, we also solved the dynamics parameters and analyze out every kind of biomass ' s frequency factor and parameters of activation energy, and established the every kind of dynamics model of pyrolysis of biomass, all of these provide the theories and basis to make sure the reactor ' s flash pyrolysis work temperature scope design and the describing of pyrolysis reactor dynamics ; ( 3 ), in order to study and ascertain the process of heat completely getting to pyrolysis time of varied size biomass particles, we observed and measured the ratio of length and diameter ( l / d ) with the varied biomass through electron microscope, we concluded the l / d ratios usually is from 5. 0 to 6. 0, the average is 5. 3 ; ( 4 ), we studied the process of biomass transiting and the theory of complete pyrolysis time with the theory of complicated heat field, we got the time ( t ) of the varied size biomass particles arriving to complete pyrolysis, and we knew that the complete pyrolysis time and the time which get to the biggest production ratio are identical, all of these studies provide the theory base for design and forecasting the flash pyrolysis reactor solid state resort time ; ( 5 ), according to the above experiment result, synthesize to make use of the engineering the mechanics, engineering the material, machine the design to learn the principle, deduce, establish the theory of rotation cone flash pyrolysis reactor material resort time ( t ) and reasonable rotation velocity ( or frequency ) relation theory ; and ( 6 ), we gave the reactor ' s smallest cone angle certain, reactor cone wall strength design theory, the reactor production ability theory, the power design method and the critical rotation velocity theory
