German restorers from the international council on monuments and sites have spent two years carefully sorting through the debris from both buddhas , lifting out the largest sections by crane ? some weigh 70 , even 90 tons ? and placing them under cover , because the soft stone disintegrates in rain or snow 來自國際紀念碑及遺址委員會的德國修復人員花了兩年時間小心過濾兩尊巨佛的殘骸,并用怪手運走最大的巖塊,有些重達70 、甚至90噸重,再把它們覆蓋好,因為軟巖在雨雪中容易崩解。

Four japonica restorer lines with the restoring genes for the genetic - cytoplasmic male sterility including jijing 85 , ji 524 , e180 and e385 have been successfully developed through the breeding method of recurrent selection , using eight japonica ptgms lines and 28 elite japonica varieties or lines selected from the north cold rice growing area in china as the breeding materials 摘要利用8份光溫敏核不育粳稻材料及28份北方寒冷稻作區優良粳稻品種(系)作為原始親本開展輪回選擇育種,育成了吉梗85 、吉524 、 e180和e385等4個具有三系恢復基因的粳型恢復系。

Abstract : the authors analyze the current status of hybrid rice breeding for superior high - yielding . the breeding strategies for superior high - yielding in hybrid rice by core approaches as the utilization of wide compatibel restorer lines and male sterile lines , construction of ideal plant type , as well as the future consideration are discussed 文摘:分析了我國雜交稻超高產育種的現狀,著重討論了以創制廣親和恢復系和廣親和不育系以及理想株型塑造等為核心的雜交稻產量超高產育種策略,并提出了今后應加強的研究內容。

This paper is focused on the design of the electronic circuits to improve the system energy resolution , including the design of the preamplifier , the shape amplifier , the base line restorer ( blr ) and the multichannel analyzer ( mca ) , discussing some problems , which should be taken into account in the design 本文著重討論了電子學線路的設計對改善系統分辨率的影響。包括前置放大電路、成形放大電路、基線恢復電路、脈沖幅度多道分析電路的設計及設計中改善系統能量分辨率應注意的問題。

Abstract : the main characters and seed set of bc1 , bc2 , bc1f2 from ms line back - crossing with the pollen of hybrid rice were studied . the appearance of a large number of self fertile plants in ms line was analyzed . the effect of introgression of restoring genes on ms line purity and hybrid yield in indica and japonica rice was discussed . it was pointed out that “ iso - cytoplasm restorer line ” was seriously reducing the purity of ms line and that hybrid rice was unsuitable for isolation zone in the seed production fields 文摘:研究了雜交稻花粉對母本不育系回交后代群體bc1 、 bc2 、 bc1f2的主要農藝性狀和育性表現,分析了不育系中出現大量自交結實株的原因,討論了恢復基因滲入對秈、粳不育系純度和雜交稻產量的影響,指出“同質恢”對降低不育系純度的嚴重性和雜交稻作制種田隔離區的不合理性。

It was shown that the absorbing rate of hybrid rice and it restorer for store material and for photo - material was 50 % and 80 % respectively , and the absorbing rate of hybrid rice was a litter higher than that of its restorer 結果表明,雜交組合及其相應恢復系的籽粒對標記儲藏物質及標記光合物質的吸收分別達到50 %和80 % ,雜交組合籽粒的吸收量高于相應的恢復系,但差異不大,說明在儲藏物質與光合產物的運輸方面,雜交組合比相應的恢復系之間無明顯差別。

It was also observed that the “ inter - grain apical dominance ” in hybrid rice was stronger than its restorer , which might be one of the main reasons for low seed setting in hybrid rice combination 強勢粒對弱勢粒物質攝取能力的優勢,可能是雜交稻籽粒結實率低下的重要原因之一。
