And pH7. 5 conditions were obtained and diffract X-rays to 2. 0〓 and 1. 8〓 resolution, respectively. Both crystals are isomorphous and belong to the space group P1; only one AB-heterodimer is in the whole unit cell.

在pH 6.5和7.5两种结晶条件下，AHP IX-bp的整体结构很相似，均方差仅为0.122 〓，但在pH 6.5条件的晶体结构中，His B61具有双重构象，这种结构的变化可能与AHP IX-bp活性的pH依赖性相关。

借助非定常时间分裂法和无波动无自由参数的NND耗散格式，建立直接求解微观分子速度分布函数的有限差分数值格式；研究并发展可用于离散速度坐标点选取和离散速度空间宏观取矩的高斯─埃尔米特无穷积分方法、等均间隔的牛顿─柯斯复合积分法、以勒让德多项式的根为积分结点的高斯─勒让德数值积分法，并应用于不同马赫数绕流模拟；通过对不同流域一维激波管问题、二维圆柱绕流问题和三维球体绕流的计算研究，并将计算结果与其他途径得到的研究结果诸如DSMC模拟值、N-S解及有关实验数据进行比较分析，创建了一套能有效模拟稀薄流到连续流不同流域气体流动问题简化的统一数值算法研究框架

The aim of this study was to reconstruct the normal structures of thoracodorsal artery in 3D images and to establish the digitized visible models of latissimus dorsi myocutaneous flap.

在平差计算中采用了三种方法，即：1）根据原始系统误差和偶然误差的假定，2）根据抛物改正曲线，3）根据修均法。

There were three major findings.(1) On the basis of the assessment of overall model fit and parameter estimates, the hypothesized second-order confirmatory factor analysis model represented an adequate fit to the sample data.(2) According to the cross-validation analysis, the second-order factorial validity of this scale was very stable.(3) This hypothesized model was invariance across these five important demographical variables, including school, gender, grade, right/left-handedness, and past experience in unintentional injury, via the testing of invariance in the multiple groups.

结果有三项主要的发现：第一、经整体暨个别的残差分析、整体模式之适配与其取代指标，以及估计参数之统计考验等结果，均指出假设此量表为二阶因素分析测量模式是相当恰当的；第二、经交互确认效度分析结果，显示此量表之二阶潜在因素结构是非常稳定；第三、经多组别不变量统计考验结果，指出此量表之二阶潜在因素结构，对於学校别、性别、年级、用手习惯，以及过去伤害经验这些社会人口变项，大致上具有因素个数、因素负荷量、因素变异数，以及测量误差变异数等不变量的特性。

Taking mapping QTL that affect leaf age growth trajectories in rice of a DH population as an example, we used 3 biological meaningful submodels and 2 orders Legendre polynomial to model the mean vector of QTL genotypes and 11 stationary and non-stationary models to fit residual covariance matrix.

以水稻一个DH群体的叶龄性状为例，我们分别用3个具有生物学意义的子模型和2阶Legendre多项式去拟合QTL基因型的均方向量，用13个平稳和非平稳模型去描述剩余协方差的变化。

By the theory of difference equation and the construction of proper vector Liapunov function, we for the first time get the sufficient conditions for the permanence, extinction and balancing survival for this ndimensional system, which are all independent on the delays, hence under peroper conditions the time delays of this system are both harmless and profitless.

通过运用差分方程理论以及构造适当向量Liapunov泛函的方法，首次得到了此类系统多维自治的情形下系统持续生存、灭绝和残存的充分条件，这些充分条件均不依赖于时滞，因而在一定条件下，此系统中的滞后因素既是无害时滞也是无益时滞。

But we don't care about Battlegrounds.

但我们并不在乎沙场中的显露。

Ah! don't mention it, the butcher's shop is a horror.

啊！不用提了。提到肉，真是糟透了。
