The basic equation and its combustion index can only be used to correctly determine combustion cheracteristics before the combustion rate has reached its maximal value,while the new combustion index can be used to correctly adjudge characteristics in the whole combustion stage.

但是，在利用热重实验曲线研究燃料燃烧特性时，许多研究者往往根据现有燃烧特性经验公式和热重曲线的特征点来研究煤的燃烧特性，但是对这类燃烧指标的可行性和局限性却很少报道。

For this reason the heavy cavalryman was protected with helmet.

这也是为什么重骑兵要带头盔，不过不是所有的重骑兵都有胆量拿敌人的刀锋来测试下自己的头盔是否坚固。

Carl Sagan has entertainingly described this phenomenon, musing about the destiny of bacteria that reproduce by dividing into two every 15 minutes. Says Sagan:"That means four doublings an hour, and 96 doublings a day. Although a bacterium weighs only about a trillionth of a gram, its descendants, after a day of wild asexual abandon, will collectively weigh as much as a mountain...in two days, more than the sun - and before very long, everything in the universe will be made of bacteria." Not to worry, says Sagan: Some obstacle always impedes this kind of exponential growth.

Carl Sagan 曾经开玩笑地解释这种现象，假设有一种细菌每 15 分钟可以分裂一次，亦即代表每一小时复制四次，一天可复制 96 次，虽然单一个细菌其重量只有一兆分之一公克重，但是只要经过一天无止尽的无性生殖，其重量可能会比一座山还重，经过两天后，甚至会比太阳还重，要不了多久所有的宇宙都将由这种细菌所组成，不过 Sagan 又说，大家不必担心，上天一定会安排障碍来阻止其倍数成长，有可能他会耗尽食物，或是毒死自己，或是有可能羞于在大庭广众之下复制。

There have been caught in Walden pickerel, one weighing seven pounds —— to say nothing of another which carried off a reel with great velocity, which the fisherman safely set down at eight pounds because he did not see him —— perch and pouts, some of each weighing over two pounds, shiners, chivins or roach, a very few breams, and a couple of eels, one weighing four pounds —— I am thus particular because the weight of a fish is commonly its only title to fame, and these are the only eels I have heard of here;——also, I have a faint recollection of a little fish some five inches long, with silvery sides and a greenish back, somewhat dace-like in its character, which I mention here chiefly to link my facts to fable.

在瓦尔登湖中，捉到过梭鱼，有一条重七磅，且不去说那另外的一条，用非常的速度把一卷钓丝拉走了，渔夫因为没有看到它，估计它稳稳当当有八磅的重量，此外，还捉到过鲈鱼，鳘鱼，有些重两磅，还有银鱼，鳊鱼（学名Leueiscus Pulchellus），极少量的鲤鱼，两条鳗鱼，有一条有四磅重，——我对于鱼的重量写得这样详细，因为它们的价值一般是根据重量来决定的，至于鳗鱼，除了这两条我就没有听说过另外的，——此外，我还隐约记得一条五英寸长的小鱼，两侧是银色的，背脊却呈青色，性质上近于鲦鱼，我提起这条鱼，主要是为了把事实和寓言连接起来。

Check to make sure any newhardware or software is properly installed ,if this is a new installation ,ask your hardware or softuare mamufa cturer for any windows rpdates you might need if preblems continue,diable or remove any newly installed hardware or software ,Disable BIOS memory options such as cathing or shadowing if you need to use safe mode to remove or disable components ,restart your comprter ,press F8to select Advanced star tup options ,and then setect safe mode

检查你的新装的硬件或者软件是否正确安装，如果是最新安装的，那么向你的硬件或者软件制造商要你需要的windows rpdates。卸载或者重装你新安装的硬件或者软件。修改BOIS（基本输入输出系统，开机时按F8就进入页面里了）存储选项，如果你需要进入安全模式来卸载或者重装部件，那么重启你的电脑，按F8按钮选择高级开机选项，然后选择安全模式进入即可。

The critical nitrogen content in heading period was used to calculate the biggest accumulation quantity of nitrogen. The latent distribution index of leaf and stem, which was the variety heredity parameter, were used to distinguish the difference in nitrogen assignment in different varieties. The dynamic content of the nitrogen accumulation before anthesis could be described with a Richards model. The dynamic content of the nitrogen remobilization in leaf with leaf area index could be described with a power model, and the nitrogen absorption of grain from soil with dry weight could be described with a power model. The dynamic content of nitrogen density in stem and spike with physiological development time could be described with a nonlinear model.

模型利用抽穗期植株临界含氮量来表达氮素最大积累量，引入叶片潜在分配指数和茎鞘潜在分配指数2个品种遗传参数来区别不同品种在器官间的氮素分配差异，采用Richards方程来描述大麦花前氮素积累动态变化；采用指数函数方程来描述叶片氮的转移量随叶面积指数的动态变化以及籽粒从土壤中吸收的氮量随干物重的动态变化；采用非线性函数方程描述茎鞘和穗部的氮浓度随生理发育时间的动态变化。

The reconnection voltage is approximately fitted by sin~(3/2)θ_(IMF/2 for its response toθ_.The ionospheric transpolar potential and the voltage along the polar cap boundary show different depondencies from that of the reconnection voltage,so it is not justified to take them as substitutes for the reconnection voltage in measuring the total reconnection rate.

2重联电压与θ_之间近似满足sinθ_(IMF/2~(3/2)关系；电离层的越级电位和极盖区边界上的电压随sinθ_(IMF/2~(3/2)的变化呈现不同的规律，一般不能简单用它们取代重联电压来量度总重联率。

Correlation between Test Weight and Kernel DevelopmentDue to the positively and significantly correlation between test weight and kernel specific gravity, it was reasonable to discuss the changes of specific gravity instead of test weight during grain filling. Fresh and dry specific gravities of maize kernels were studied after pollination till to the maturity.

玉米容重与籽粒发育的关系由于容重与籽粒比重间的高度正相关性，用比重在籽粒发育过程的变化趋势来间接反映籽粒灌浆过程中容重的变化是完全可行的。

Recently, acute poisoning frequently happens which is caused by the release of chlorine in the production process,as the dense gas,chlorine dispersion model contain continuous diffusion and instantaneous dispersion, and we can separately use dense gas flat plume model and dense gas box puff model to calculate the density of the gas.

risk analysis ； dispersion ；近来，生产过程中氯气泄漏引起的急性中毒事故频繁发生，作为重气的氯气泄漏扩散分为连续扩散和瞬间扩散二种模式，并且分别应用重气云羽平板模型和重气云团盒子模型来计算重气扩散浓度。

It reallocates only once, to 65536, rather than just to the size needed, so it can be less memory-efficient than Chuck's patch (though, like his patch, it only reallocates if the response is larger than PACKETSZ, which defaults to 512 bytes). After reallocating, it forces a TCP query, rather than requiring the resolver library to do so (avoiding an extra round-trip between qmail and the name server, though if they're on the same machine or local network this is not a big worry).

它仅仅重分配一次缓存为65536字节，而不是分配正好需要的大小，所以它可能比Chuck的补丁内存效率低一些(虽然如此，像Chuck的这个补丁仅在反馈长度大于PACKETSZ--默认为512字节--情况下重分配缓存)重分配之后，它强制一个TCP查询，而不是要求解析库来作查询(尽管在qmail和名字服务器同在一个机器或者同在一个局域网络里面的情况下，这种查询不算什么负担，这样作还是避免了在qmail和名字服务器之间额外的往返)。

As she looked at Warrington's manly face, and dark, melancholy eyes, she had settled in her mind that he must have been the victim of an unhappy attachment.

每逢看到沃林顿那刚毅的脸，那乌黑、忧郁的眼睛，她便会相信，他一定作过不幸的爱情的受害者。

Maybe they'll disappear into a pothole.

也许他们将在壶穴里消失
