We deeply understood the work method with 8259A in this topic, work principle and work condition;Knew to break off existent important meaning in the meantime, break off the popular comprehension can think to be a "abnormality", under the sistuation that have excrescent occurrence output circumstance, at two procedures which put in the at present thing to win election to choose to even need to immediately carry out to respond to, is in the interruption say of have the initiative class.

在本课题中我们深刻的了解到了8259A的工作方式，工作原理和工作状况；同时知道了中断存在的重要意义，中断通俗的理解可以认为是&异常&，在有异常发生的情况下产生的情况，在两件摆在眼前的事物中选择更需要立刻执行响应的程序，即是在中断中所说的优先级。

But the rate of mammitis will increase at the speed of 2％, at the same time, the number of daughters and sons of test bulls is not large enough for good accuracy for estimating test bull breeding value, so the breeding scheme in effect need to be improve.

C、现行的育种方案的育种成效不甚理想，世代间隔为5.42年，投入产出比为1∶11.50，但乳房炎发病率提高，公牛后裔测定的后代数低；现行方案还有较大的改进余地。

The mean generation interval of the flock is 5. 42 years of the current breeding scheme, and the ratio of input and output is 1∶11. 50, but the rate of mammitis will increase at the speed of 2%, at the same time, the number of daughters and sons of test bulls is not large enough for good accuracy for estimating test bull breeding value, so the breeding scheme in effect need to be improve.

D、在影响育种效益的诸因素中，单一的加大群体规模、育种群比例以及每年选留测验公牛数将在一定程度上提高育种效益和遗传进展，但随选留种子公牛数提高将降低育种效益和综合育种值遗传进展；在育种实践中应尽量扩大育种群规模和主动育种群比例。

Beijing environmental problems hold severe, and atmospheric and water pollute, soil and water loss, hot island and yawp are leading problems,and take on territorial characteristic. Based on research on relativity between urban forest and these environmental problems, urban forest can effective improve environmental quality in Beijing. And for the aim of improve environmental quality, Beijing forest overlay should attain 35% at least in citywide range, and local-areas being severe environmental problem should be provided with higher forest overlay.5. Through the study on urban forest needed capacity, Beijing's forest coverage is up to par in citywide range, but montanic forest coverage, plain covered with trees and average forest area are lacking, and CO2 and O2 balance is incapable;form the point of heat and balance CO2 and O2 balance,urban forest the city zone and suburb is lack. There is urban forest developmental potential space,but the city zone and suburb area need be compensated form urban forest in circumjacent region.6. On the based of the above results and ecological network system, the author drived whole region into city area, plain and mountain area are needed at the point of planning thoughts of running-through forests and water .

根据城市森林与北京市主要环境问题的相关性分析，城市森林在改善这些环境问题中具有重要的作用，为有效改善这些环境问题，整个北京市域范围内森林覆盖率至少达到35%，并且分布比较均匀，环境问题严重的局部区域需要不同程度增加森林覆盖率。5、通过对北京市城市森林需求量研究发现，虽然在市域范围内北京森林覆盖率达到了国家标准，但是山区森林覆盖率、平原林木覆盖率、城区人均森林面积不足；从区域热平衡和碳氧平衡角度分析，城区和郊区不能满足本区域的城市森林需求量，虽然北京市城市森林具有一定的发展潜力，整体上基本可以满足城市需要，但是这些区域需要依靠周边区域城市森林的补偿。6、根据以上的研究结果，以中国森林生态网络体系建设的点、线、面布局理念为指导，以&林网化——水网化&作为优化理念，将北京市整个市域划分为城区近郊区及其辐射区域，平原区和山区三大区域，依据三大区域特点进行城市森林布局优化。

These findings have suggested the development stages at which to transplant cells--for instance, photoreceptor cells need to be relatively more mature than stem cells, according to Thomas Reh, who studies retinal development at the University of Washington.

在华盛顿大学从事视网膜发育研究的Thomas Reh表示，这些发现提示，进行细胞移植--比如感光细胞的移植时，被移植细胞的发育阶段应比干细胞要相对成熟一些。

With the increasing transportation of liquid chemicals in bulk by ships, the risk of the chemicals spill is getting higher and higher. So the reasonable numerical modeling of the spilled chemicals at sea is a key technique for the risk assessment and contingency decision-making. The sinkable chemicals spilled at sea always ended in sediment, so the design of decision-making support system for sinkable chemicals spilled shipboard have academic and applied sense.Based on the analysis for the environmental harm caused by the transportation shipboard of chemicals and research on related ordain in the international common and intestine law , the paper analysis the impelling need of establishing related respond system for contaminative accident.

随着海上液体化学品运输、中转量的不断增加，化学品泄漏风险也日益增加，对海上泄漏化学品行为进行合理、可信的数值模拟，而沉降型化学品由于最终进入沉积物而可能带来更大的潜在危险，故并在此基础上构建GIS支持下的海上溢漏事故应急决策支持系统具有重要的理论意义和实用价值。

The next year I did better still, for I spaded up all the land which I required, about a third of an acre, and I learned from the experience of both years, not being in the least awed by many celebrated works on husbandry, Arthur Young (10) among the rest, that if one would live simply and eat only the crop which he raised, and raise no more than he ate, and not exchange it for an insufficient quantity of more luxurious and expensive things, he would need to cultivate only a few rods of ground, and that it would be cheaper to spade up that than to use oxen to plow it, and to select a fresh spot from time to time than to manure the old, and he could do all his necessary farm work as it were with his left hand at odd hours in the summer; and thus he would not be tied to an ox, or horse, or cow, or pig, as at present.

第二年，我就干得更好了，因为我把总需要量的全部土地统统种上了，只不过一英亩的三分之一，从这两年的经验中，我发现了我没有给那些农业巨著吓倒，包括亚瑟·扬的著作在内。我发现一个人如果要简单地生活，只吃他自己收获的粮食，而且并不耕种得超过他的需要，也不无餍足地交换更奢侈、更昂贵的物品，那末他只要耕几平方杆的地就够了：用铲子比用牛耕又便宜得多；每次可更换一块新地，以免给旧地不断地施肥，而一切农场上的必要劳动，只要他夏天有空闲的时候略略做一做就够了；这样他就不会像日前的人们那样去和一头牛，或马，或母牛，或猪猡，捆绑在一起。

I ask Ross Thacker, a research officer at the authority, whether the HFEA is regularly in need of yellow police tape to keep protesters at bay.

我问Ross Thacker，一个在管制局的研究人员，这座大楼会不会经常被围上警察的黄色警告带，以防示威者进入大楼。

Zeiss began to make improvements in microscopes, offering simple microscopes and in 1857 introducing the first compound (which employ an objective and an eyepiece) microscope "Stand I". In 1861 Zeiss compound microscopes are declared to be "among the most excellent instruments made in Germany" and he is awarded a Gold medal at the Thuringian Industrial Exhibition. By 1864 the need to house some 200 employees results in another move of the workshop to a third larger site at Johannisplatz 10. In 1866 the 1000th microscope is delivered; the Carl Zeiss shop is recognized throughout European scientific circles for the quality of its microscopes.

蔡司开始对显微镜进行改进，生产简便显微镜，并在1857年推出了第一种复合显微镜&Stand I&型。1861年蔡司复合显微镜被认为是&德国制造的最出色的仪器&，并被授予图林根工业博览会金奖。1864年由于已经拥有200名雇员了，工厂不得不第三次搬迁到Johannisplatz 街10号的更大的地点。1866年生产了第1000台显微镜；欧洲科学界通过高质量的显微镜而认识了卡尔蔡司工厂。
