Gscoh gs fsR, gscoh as the solid fraction when the formation of the continuous dendrite framework, fsR as the maximum solid fraction after recalescence,βs as the solidification shrinkage of the primary phase,μas the dynamic viscosity of the liquid, a as the length of L/S coexistence zone,λ2 as the secondary dendrite arm spacing, and tf as the total solidification time. High temperature recovery and recrystallization taking place in these fragments during further cooling results in the further grain size decrease.

It was suggested that aging did not only influence diastolic filling period, but also influence STI. 3. With increasing age, whether at rest or during exercice, fractional shortening of minor semiaxis, mean velocity of circumferential fiber shortening, cardiac index and ejection fraction did not change, but immediately post pacing, PEP prolonged and PEP/ LVET increased in elderly group and did not change in young group. It was suggested that STI was sensitivity in detecting systolic function of LV. 4. There was a good correlation between aging and decreased compliance and diastolic function of left ventricle which was manifested by a reduction of early diastolic peak folw velocity, time-velocity integral of early diastole, 1/3 filling fraction (1/3FF)(r=-0.958,-0.875 and -0.937, P＜0.01～0.001) and a significant compansatory increase in peak flow velocity of atrial contraction, time-velocity integral of atrial contraction, the ratio between APFV and EPFV and the ratio of ATVI and Total TVI (r=0.958, 0.956, 0.966 and 0.986, P＜0.001) and the prolongation of Dec T and RFP with increasing age. It was particularly true for the subgroups above the age of 50 years.

静息状态下收缩时间间期与年龄无相关性，负荷后即刻，老年组射血前期延长(P＜0.05)，射血前期与射血期比值加大(P＜0.05)，青年组无变化，提示年龄因素亦影响STI，但由于静息状态下得到代偿，STI变化往往表现不明显。3、静息及负荷状态左室短轴缩短率、平均周径缩短率、心指数及射血分数均不随年龄增长而变化，而负荷后即刻老年组PEF延长，PEP/LVET加大，提示STI是检测左室收缩功能的敏感指标。4、随年龄增长，心房收缩期充盈峰值流速、流速积分、充盈分数及心房收缩期与舒张早期充盈峰值流速之比值显著增高(r＝0.958、0.956、0.986及0.966，P均＜0.001)，舒张早期充盈峰值流速及流速积分、1/3充盈分数(1/3FF)下降(r＝-0.958、-0.875及-0.937，P＜0.01～0.001)。

对犯每一错误类型的学童而言，类型九之错误类型最困难，犯错误类型二（不了解分数符号平分意义）的学童在其他概念的表现情形良好，另外八个错误类型的学童，在等值分数概念表现最差，简单分数概念表现最好。

There are 26 questions asking teachers to predict the correct percentages of students and they include the concept of equal dividing, simple fraction, unit of quantity and equivalent fraction.

Experimental results indicate that there is a critical value of carbon fiber weight fraction which effects the electrical properties of SCF/NBR.When carbon fiber weight fraction comes to this critical value,volume specific electrical resistance and static ...

通过实验发现，碳纤维的含量对短碳纤维／丁腈橡胶（ShortCarbonFiber／NitrileButadieneRubber）电性能的影响，存在一个临界值，当碳纤维的含量达到此临界值时，SCF／NBR的体积比电阻和静电电压都得到显著的降低。

By tracing the antifungal and antibacterial activities of the volatile oils, it is found that the major active site in fiuit oil of Litsea mollis is aldehydic fraction such as citral, the major active site in oil of Thymus quinquecostatus is phenolic fraction such as thymol and the major active site in ginger oil is high boiling-point terpenic constituents such as β-caryophyllene, eudesm-4 (14)-en-11-ol, et al.

And they say there is no fate, but there is, it's what you create. And even though the world goes on for eons and eons you are only here for a fraction of a fraction of a second. Most of your time is spent being dead or not yet born. But while alive, you wait in vain wasting years for a phone call or a letter or a look from someone or something to make it all right. And it never comes, or it seems to, but it doesn't really. So you spend your time in vague regret or vaguer hope that something good will come along. Something to make you feel connected. Something to make you feel whole. Something to make you feel loved. And the truth is I feel so angry. And the truth is I feel so fucking sad. And the truth is, I've felt so fucking hurt for so fucking long. And for just as long, I've been pretending I'm okay, just to get along, just for…I don't know why.

大家都说没有所谓的命运，有的只是你所创造的东西，即使世界年复一年的转动，你也只是这一秒钟里极小的一块碎片，你们大部分的时间都留在生后或者生前，但当你们活着的时候，你只是徒劳的等着，浪费几十年去等来自某个人或某件事的一个电话、一封信或一次见面来使自己心安，但那从来都不会或者似乎要发生，但那真的不会发生，所以你再次花时间去茫然的后悔或茫然的希望接下来会遇上好事情，让你感到自己不是与世隔绝的，让你感到自己的存在，让你感到自己是被爱的，而事实是我很生气，而事实是我很伤心，而事实是我觉得我被伤害了很多年了，而同时我还一直假装我自己没事，去适应，去。。。

All this to say that I'm glad filmmaking hasn't become completely ironic. I can enjoy an ironic film as much as the next person, but they usually involve a message of some sort. One that's delivered in a smirkingly clever way that requires little in the way of talent.

所有这些都是说，我很高兴电影制作没有变成完全讽刺艺术，我可以和下一个人一样享受讽刺电影的乐趣，虽然他们经常会被划归到一定级别，技术方面不需要很高的才能。
