On this foundation, this text sums up the basic principle of permeating mathematics method of thinking in junior high school mathematics: Announce to public and permeate," show"and " hidden" combinative, follow the sequence and advance gradually, spiral raising, make a point of the process, permeat on time, sum in time, system induce, problem solving, outstanding and deep, respect difference, layering teaching, come from knowledge, return to knowledge.

在此基础上，本文总结了初中数学中的数学思想与方法渗透的基本原则：揭示渗透，"潜""显"结合的原则，循序渐进，螺旋上升的原则，注重过程，适时渗透的原则，及时小结，系统归纳的原则，问题解决，突出深化的原则，尊重差异，分层教学的原则，源于知识，回归知识的原则。

Heat flux increases remarkably in spring, so layering comes into being gradually and concentrates on the central BS where tidal mixing is weak; whether the range or intensity culminates during the Summer Solstice; stratification is weakened in accompany with the decrease of heat flux in the fall, and is still apparent in BS strait; the gale enhances vertical stirring of sea water, so no obvious stratification exists in winter.

春天海表热通量显著增强，层化结构也开始形成，主要分布在潮汐混合较弱的中央水域；夏至时节层化结构无论是发生范围还是层化强度都达到极致；进入秋季，层化强度伴随着海表热通量的减少而削弱，分布区域也逐步向渤海海峡转移；冬季大风进一步增强了海水的垂向混合，此时渤海不再有垂向分层。

In order to optimize tolerance values for an assembly system, a model for geometric dimension tolerance optimization was established and an algorithm for optimal tolerance design was proposed. The algorithm is divided into two stages: at the first stage, design centering problem is solved and statistical optimization for further lowing the cost is solved at the second stage.

为优化装配系统中公差链的公差值，建立了几何尺寸公差的优化模型，并提出公差的分层优化设计算法：第一层，解决设计公称值居中的优化问题；第二层，解决进一步降低成本的概率性优化问题。

But at least their research objects are highly crossed and deeply storied, closely connected as a triangular combination.

至少它们的研究对象是高度交叉的、深度分层的，或分区段紧密连接的一种类似三角形的综合体。

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%.
