The standard cell phone style discrete button direction pad with a center action button is a good interface for one handed navigation and selection, but it sucks for games, where you really want a game boy style rocking direction pad for one thumb, and a couple separate action buttons for the other thumb.

传统的手机往往在四个方向键中嵌入一个中心动作按钮，这种按键布局方式有利于人们用单手来操作，但对于游戏来讲，确是糟透了，在玩手机游戏时，你可能真的希望自己的一只手能够操作一个Game Boy风格的方向键，而另一只手来控制一对相分离的动作按钮。

The results are following:1 QTL mapping for resistance to Verticillium wilt in G.barbadenseA highly tolerant to Verticillium wilt G.barbadense var.Hai7124 and a highly sensitive to Verticillium wilt G.hirsutum var.Junmian 1 were crossed and F_1 seeds produced self-pollinated F_2 progeny which comprised 128 individuals and BC_1 was produced from a cross between(Hai7124×Junmian 1)×Junmian 1.The BC_1F_1 individuals were self-pollinated to produce a BC_1S_2 population,resulting in 96 families of BC_1S_2.A genetic map included 36 linkage groups with an average distance of 7.29 cM between markers and covered 2726.89 cM was constructed using F_2 population.

本研究利用分子标记的方法，分别对海岛棉和陆地棉抗黄萎病QTL进行了定位，并对陆地棉的产量和纤维品质性状的QTL进行了初步定位，主要结果如下：一、海岛棉抗黄萎病QTL定位用一个抗黄萎病海岛棉品种海7124和一个陆地棉感病品种军1配制杂交组合，得到一个含128个单株F_2分离群体，同时与军1回交得到含96个单株的BC_1群体，自交产生BC_1家系。

A precise method was established as follows: hydrogenperoxide should be separated from flavonoids by passing the flavonoid solutionsthrough alumina columns before the measurement and the amount of hydrogenperoxide generated from self-oxidation of the flavonoids should be deducted.

提出并确立了正确的方法：准确测定黄酮类化合物辐照体系中的过氧化氢G值，必须先用柱色谱法将过氧化氢从辐照体系中分离出来，再扣除黄酮类化合物因自氧化而产生的过氧化氢的量，才能得到正确的过氧化氢G值。

Soil samples were collected from different ecological conditions. More than 70 Streptomyces hygroscopicus strains were isolated from the soil samples. Fermentation centrifugal supernatant of the strains were used as biocontrol agents to bioassay the seedling of rice and barnyard grass and rice pathogens of sheath blightand bakanae. Three strains showed good effects of inhibitingbarnyard grass seedling, the another three strains well inhibited the growth of rice pathogenic fungi.

从国内外不同生态条件下采集的土壤标本中分离到70多个吸水链霉菌，用其发酵离心上清液对水稻、稗草秧苗和稻纹枯病菌、恶苗病菌进行生物测定，结果有3个菌株对稗草根的生长具有较好的抑效果；有3个菌株对水稻病原菌有很好的抑制生长作用。

Other major figures: Robert Koch (first person to isolate bacteria in pure culture; discovered the agents of cholera and the cause of tuberculosis, and used his own criteria to distinguish a bacterial culprit causing a disease from an innocent microbe); and Joseph Lister (who used carbolic acid spray to kill bacteria, insisted that antiseptics be used on hands, instruments, and dressings and made it safe to do major surgery).

其他的重要人物：Robert Koch（纯培养分离出细菌的第一人，发现霍乱试剂和结核病的原因，使用他自己的标准来区别致病菌的非致病{良性}菌）；还有Joseph Lister（使用石炭酸喷雾剂杀菌，坚持用消毒剂消毒手，器械和敷料，使其在大外科手术中更为安全）。

But the classical differential centrifugation technique needs special ultra-speed centrifuger and deuterium oxide, which limits the research and application of them.

本研究利用外来体的物理特性，用基于孔径分离的生物膜离心过滤法制备得到了外来体，有效的降低了外来体研究及应用的技术门槛。
