Lastly,we present an algorithm to isolate real roots of a univariate spline, i.e., computing asequence of disjoint intervals such that each of them contains exactly one real root of agiven spline function, which is primarily based on the use of Descartes\' rule of signs withits B-spline coefficients and de Casteljau algorithm of B?

最后，基于B-样条系数的Descartes符号准则和Bézier曲线的de Casteljau算法，我们给出了一元样条实根分离算法，也就是计算出一列不相交区间，使得每个区间恰好只包含此样条函数的一个实根。

The calculation of initial alignment direction cosine matrix between SINS body frame and navigation reference frame is expanded into three parts:(1) the DCM between i0 frame and n frame is easily obtained via local geographical coordinates and initial alignment time;(2) by expressing SINS specific force equation in b frame and by the aid of external velocity log, the constant DCM from i(subscript 0) frame to i0 frame is achieved;(3) attitude updating using gyro samples gets the DCM between b frame and i(subscript b0) frame.

将捷联惯组坐标系与导航坐标系之间的初始对准姿态矩阵的实现分解为三步骤：(1)通过地理位置和初始对准时间求解i0系至n系的变换矩阵；(2)通过惯导比力方程变形，引入刚速仪速度辅助，求解从i(下标 b0)系至i0系的常值变换矩阵；(3)使用姿态更新算法实时计算b相对于i(下标 b0)系的变换矩阵。

The venom of elapid snakes contains a number of small proteins that display a broad spectrum of pharmacological activities.In study on the neurotoxin from the venom gland of Bungarus multicinctus,five cDNA sequences (MNCTL1-a,MNCTL1-b,MNCTL1-c,MNCTL1-d and MNCTL2) encoding two novel proteins were obtained from the total RNA by reverse transcription-polymerase chain reaction.

采用SMART技术和RT-PCR方法，从同一个银环蛇毒腺中克隆到了5 种尚未报道过的心脏毒素类似物全长cDNA序列（MNCTL1-a、MNCTL1-b、MNCTL1-c、MNCTL1-d和MNCTL2）。5种序列中，MNCTL1-b、MNCTL1-c、MNCTL1-d和MNCTL2的长度均为505 bp，包括5′非翻译区32 bp，3′非翻译区212 bp和其余261 bp组成的一个完整开放阅读框；MNCTL1-a 由于3′非翻译区24 bp的缺失，全长cDNA仅为481 bp。
