The result shows that all the three polynomials can be used to reconstruct the wavefront correctly, the reconstruction precision of the orthogonal Zemike polynomial in square zone is comparatively better though the difference of the reconstruction precision among the three polynomials is not apparent.

结果表明：对于方形区域上的波前重构，上述三种多项式都能正确地重构出待测波前，它们的重构精度差别不大，相比之下，方域上正交的Zernike多项式的对待测波前的重构精度更高。

First, the algrithm classify the measurement characteristics as point, line and surface which can be classified to conicoid and free surface. Then, this algorithm establishes the parametric equation according to various features. After that this paper brings forward the characteristic parameters utilising least square method with several characteristic points. Finally high precision probe radius compensation is carried out according to the features.

该算法首先把测量特征分为点、线、面3种基本特征（其中面特征又分为二次曲面和自由曲面），然后建立各种特征的参数方程，利用测量得到的少量特征点，采用最小二乘法拟合得到被测特征的参数，最后根据被测特征参数进行高精度半径补偿。

The results showed that, SiCYC1A and SiCYC1B were both detected in dorsal petals of wild type and peloria at early bud stage (3mm in diameter) but not in later stage (30 mm in diameter).

然而，野生型和变异型的五片花瓣在早期花苞都可侦测到SiCYC1A和SiCYC1B的高表现量，但到了开花晚期时两者的表现量都几乎侦测不到。

The result of the research on children's learning profile was found that the observation record that derived from teaching process and interview analysis that got from two text-based tests. The students who are high and intermediate achievers can make first-order and second-order conditions on four-type regular problems by means of discussion and presentation in class. In addition, they can solve problems utilizing "perceptibility" when doing two text-based tests.

研究结果显示，藉由教学过程的观察记录及两次施测后的访谈分析所获得的学童学习历程观之：高成就及中成就组学童藉由讨论与发表，在四种型态问题皆能展现出察觉规律的一阶至二阶层次能力，并能在两次施测时运用察觉能力成功解题。

During the process of filling, the water heads of all piezometers are higher than the surface of the soil. Moreover, the deeper the piezometer is ebedded, the higher the piezometric head will be.

饱和粉土和黏性土在填筑过程中，底板所受浮力极大，并可能超过被其排开的饱和土的重量，且测压管水头在填筑过程中均超过填土面高度，埋置越深的测压管水头越高。

Polony DNA sequencing provides an inexpensive, accurate, high-throughput way to resequence genomes of interest by comparison to a reference genome.

聚合酶DNA测序提供了一个便宜的，准确的，高通量的方式，通过和一个参考基因组比较来重测序感兴趣的基因组。

Since the human genome was sequenced six years ago, the cost of producing a high-quality genome sequence has dropped precipitously.

从六年前人类基因组测序的完成，高品质的基因组测序结果的花费已经明显降低。

The compensation current is then directly related to the primary current by the turns ratio of the primary winding to the compensation winding.

此方法的优点是不必使检测磁芯驱动至饱和（实际上不到600GS），对被测电路的干扰小，可以测量高精度的直流电流，并与被测电路隔离。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。

The cost of moving grain food products was unchanged from May, but year over year are up 8%.

粮食产品的运输费用与5月份相比没有变化，但却比去年同期高8％。
