Therefore, the multi-stage interaction structures with losses and severed structure were more stability for absolute instability and gyrotron backward oscillations. This study presents a nonlinear analysis of typical oscillations, including absolute instability, gyrotron backward oscillation and reflective oscillation. The multi-stage gyro-TWT seem to increase effectively the start-oscillation currents of the absolute instability, gyro-BWO, and reflection oscillation.

This section presents two kinds of characteristic schemes, one is the natural use of the usual backward Euler characteristic difference scheme ( [60] ) onto the triangular mesh, the other replaces the backward Euler's method by modified Euler formula to approximate the characteristic differential equation, so that the discretization for characteristic curve can get up to second order accuracy.

本节给出了两种三角形网格上的特征差分格式，第一种是通常的向后Euler型特征差分格式（[60]）在三角形网格上的自然运用，第二种采用§3.3、§3.4的离散思想，使用改进的Euler公式代替向后Euler公式来近似特征微分方程，使其对特征线的离散达到了二阶精度。

The basic concept in these sections is replacing backward Euler's method by modified backward Eulers's method to approximate the characteristic differential equation and discretizing the convection-diffusion equation at the middle point of the approximate characteristic curve, which will make the convective term get up to second order accuracy.

这三节的基本离散方法是用改进的Euler公式代替向后Euler公式来近似特征微分方程，并且将近似特征线的中点作为离散节点，使得对流项的离散精度提高到二阶，对于扩散项，将其转移到待求时间层进行离散。

Huang and Lin proposed the weak solution concept for Backward Stochastic Differential Equation This paper based on the predecessor's work , gives the weak solution concept for Backward Stochastic Differential Equation with continuous martingale,uses the Girsanov transformation, obtains its weak solution of the existence of a necessary and sufficient conditions, and on this basis obtains its weak solution of the existence of sufficient conditions,these sufficient conditions weakened the drifting coefficient which requested in the existence uniqueness of strong solution to satisfy the Lipschitz condition the request.

本文在前人研究的基础上，给出由连续鞅驱动的倒向随机微分方程弱解的概念，利用Girsanov变换，得到其弱解存在的存在的一个充分必要条件，并在此基础上得到了其弱解存在的一些充分条件，这些充分条件减弱了在强解的存在唯一性中要求的漂移系数满足Lipschitz条件的要求。

Its on the oriental stage that a series of oncoming and dormant Oedipus tragedies-incest tragedies, with which the westerners are so familiar regardless of performance on the somewhere strange stage, are highlights, so that the western spectators not only can enjoy the different exotic cultural charms, but from the commanding perspective fell the superiority of their own culture in this fabricated cultural context featured with backward, isolation and far from the reality. In addition, Zhang prefers to the method of time lagging in the film text formation, so that the textual times usually drag back to the past on purpose such as 1930s, 1940s, per-anti-Japanese war period as well as 1960s and 1970s; apart from this, the far-off areas far from the cultural center are chosen as the film space, all which get together to set up a static, stagnate and hiding Chinese traditional cultural context symbolized by backward, barbarousness and ignorantness to satisfy the male desire.

为了营造这个虚拟舞台，张艺谋影片中的采用了时间的滞后性策略，影片中的故事本文时间均选择了过去：十九世纪三十、四十年代，抗战前期，六七十年代；影片中的本文空间均选择了远离文化中心的边缘地带，通过时间的滞后策略和空间的边缘策略来满足一个停滞的、凝固的、静止的落后而由愚昧野蛮的中国传统文化语境；将处于社会边缘的女性放置在其中，利用观众位置的双重性认同结构，巧妙利用女性这一表层可见视觉中心和读解影片时意义渐隐的策略来遮掩和移位其真正的作者意识形态：即重复再一次对女性的观看，满足东西方男性的窥视欲望。

Still will be the same as the Ministry of finance at the same time, research is built fall into disuse backward produce can exit a mechanism, raise capital allowance standard, exit condition, personnel to install buy law to wait, fall into disuse since work up backward produce can incentive mechanism.

同时还将会同财政部，研究建立淘汰落后产能的退出机制，提出资金补助标准、退出条件、人员安置办法等，逐步建立起淘汰落后产能的激励机制。

One day, Hershey was walking backward on the walkway while my grandfather was pushing a vat of chocolate up the ramp. Bump. Clunk. Ker-plop! Hershey fell backward into the vat. Everyone else held their breath and ran up to pull him out. Grandfather froze in fear. Was he going to lose his job?

一天，hershey在人行通道上倒着走路，这时候我祖父正推着大桶上了斜坡，咣当，克朗，扑通，hershey被大桶撞翻了压倒，所有的人都一下子停下来屏住呼吸，然后快跑过去把老板拉出来，祖父的心一下子被恐惧压倒，他可能会为此而失去工作了。
