The precision of integration can be evidently improved by using smooth function transition, adaptive step size change method, implicit integration and predictor corrector method. Increasing the order of the LMM may not improve the precision in this case.

采用光滑函数过渡、自适应变步长技术及隐式和预测校正等方法，可以有效地提高数值计算精度，而提高方法的阶次不能有效提高精度。

The result shows that the parameters in the RTT estimating modal are changing as time and self-adapted, so it can track RTT quickly and dynamically. The improved RTO arithmetic solves the problems that how to select wrap and weight when the sampling rate is high and the sender has a heavy loading.

结果表明：RTT估计模型中的参数是时变的，并且是自适应的，因此能迅速而又动态地跟踪RTT；改进的RTO估计算法解决了采样率高、发送方负载大时，偏差权重的选择等问题。

Mineralizing fluid migrated, concentrated and allocated in the fractured zone between granite and metamorphic rock, it was a good canal for Rn, U, Tb and K, added intense sericitization, in geophysical exploration we found that y -ray spectrometry, Radon spectrometry can reflect the allocation of fractured zone, X-ray fluorescence analysis in laboratory can effectively find alteration envelope, elements geochemical abnormality, soil primary and secondary halo, then find deposits allocation.

F. pumila had the strongest capacity to adhere to walls, and it formed a quite good covering landscape by means of a large quantity of adventitious roots. Furthermore, it was tolerant to shade, and the effects of shading on its growth and landscape covering were very small. P. heterophylla had the rapidest growth and covering speed, and it adhered to walls by adhesive discs, but was defoliated in winter or after a long period of shading. The other three vines climbed walls using adventitious roots, and their adhering capacities were all relatively poor. However, E. fortunei still formed a relatively good covering due to its rapid growth and emerald leaf colour. After shading for four months, leaves of F, pumila, C. grandiflora, and P. serpens became thin, and accordingly their leaf weight per unit area significantly decreased. Shading also reduced chlorophyll contents of C. grandiflora and E. fortunei but enhanced those of F. pumila and P. serpens, It did not influence leaf thickness, leaf weight or chlorophyll content of P. heterophylla. Whether shaded or not, the relationship between Pn and PAR for each species could be expressed as y=alnx+b, and furthermore there was a significant (P.01) correlation between them. Pn and LCP values for all five lianas also significant (P.01) correlated. Shading reduced LCP values of P. heterophylla, C. grandiflora and E. fortunei but increased LSP of F. pumila.

结果表明，1薛荔对墙体附着力最强，它依靠大量的不定根吸固在墙体上，形成很好的覆盖效果，而且薜荔耐荫，遮光对其生长与覆盖的影响很小；爬墙虎的生长与覆盖速度最快，它主要依靠吸盘吸固墙壁，但在冬季或长时间遮光后出现明显落叶现象，影响其覆盖景观；其他3种都依靠不定根沿墙面攀援，附着力相对较差，但扶芳藤由于生长较快，叶色终年保持翠绿，也能形成相对较好的覆盖效果；2遮光4个月后，薛荔、凌霄和蔓九节的叶片变薄，相应地这3种植物单位面积的叶片重量都显著减轻；遮光还使凌霄和扶芳藤的叶绿素含量减少，使薛荔和蔓九节的增加，但对爬墙虎的叶片厚度、叶重和叶绿素含量都不产生明显影响；3无论遮光与否，5种植物的Pn与PAR之间的关系都可用y=alnx+b表示，并且都达极显著相关，Pn与光补偿点之间亦呈极显著相关；遮光还使爬墙虎、凌霄和扶芳藤的LCP下降，并使薛荔的光饱和点升高。

We find that this order parameter can reflect the symmetry changes of the two crystals perfectly. There are two kinds of antiferroelectric models for the simple cubic lattice.

利用该序参量研究了典型的反铁畸变晶体-PZT晶体和钛酸锶晶体，发现它能很好地说明这两种晶体θ相变前后对称性的变化。

If you're a sloucher, trade in your chair for an exercise ball, which forces you to sit taller, says Andrew Weil, M.D., author of Healthy Aging (Knopf,$28, www.amazon.com).

医学博士、《健康变老》一书的作者Andrew Weil说如果你是低头垂肩者，把椅子换成一只锻炼球，它能迫使你坐地更高。

But the unthreshed sheaves remaining untouched seemed countless still, notwithstanding the enormous numbers that had been gulped down by the insatiable swallower, fed by the man and Tess, through whose two young hands the greater part of them had passed.

她是唯一一个还在机器旁边干活的女人，机器不停地转动，振动着她的身体，麦垛变矮了，从而把她同玛丽安和伊茨隔开了，因此她们也不能像从前那样互相替换一阵了。

I thought him half a lunatic, half knave, And told him so, but friendship never ends; And what if mind seem changed, And it seem changed with the mind, When thoughts rise up unbid On generous things that he did And I grow half contented to be blind!

我曾认为他是半个疯子，半个痞子，我这样对他说过，但我们的友谊却又能持久；要是心灵看似变了又如何，似乎这友谊确已随心灵而改变，当思绪不由自主地升起想起他做过的那些慷慨事迹我便是瞎了眼也有些情愿！
