As compared with the traditional irrigation-traditional fertilization, the following results of the improved optimized irrigation-optimized fertilization were obtained: significantly higher nitrogen use efficiency; the like tiller number per unit area, percentage of the tiller ear number/the tiller number, the ear number per unit area, the greatly reduced grain number per ear, and significantly heavier weight of 1, 000 grains; a trifle taller plants; shorter base internode length, a bit more weight per unit internode length, longer internode length under ear; almost the same LAI values in middle and later stages; coincident process of dry matter accumulation from straight growth onwards, a little more dry matter accumulation amount from earing to maturity; a little longer flag leaf, 2〓 leaf, 3〓 leaf (but the three leaves were shorter than those of the optimized irrigation-traditional fertilization) and shorter 4〓 leaf from top, a bit reduced total area of these leaves; almost the same leaf thickness, mean canopy leaf tilt angle, light extinction coefficient , ratio of light penetration in the upper, middle and lower parts of the wheat canopy, and fair plant type; almost the same senescence process of flag leaf; and increased root amount in 0-120cm soil layer and smaller rate of progressive decrease of the root length density and root weight density with soil getting deep, which can strengthen the resistance to adverse conditions such as water stress in the later stage.

在优化水肥条件下，冬小麦总分蘖数、成穗率及单位面积穗数与传统水肥比较接近，但穗粒数显著减少，千粒重显著提高；株高稍有增加；基部节间长度缩短，充实度略微增高，穗下节间增长；中后期LAI与传统水肥的LAI值基本吻合；起身至成熟干物质积累量动态变化过程与传统水肥十分接近，但抽穗至成熟所形成的干物质量增加；上三叶变长（但上三叶长度增加幅度小于优化灌溉-传统施肥处理），倒4叶变短，总叶面积略有减少；叶片厚度、冠层平均叶倾角、消光系数、冠层各层的透光率与传统水肥差异很小，株型较好；旗叶叶绿素含量动态变化与传统水肥十分接近；0-120cm土层的总根量明显增加，上层根群和深层根群的差异最小，有利于提高小麦后期的抗逆力。

On the contrary, the absconding of the second part is content of crime constitution condition basic on the conduct of causing traffic casualties, and it has independent position by assessment in legislation. Those who cause death because of their absconding in the third part are aggravated offense by consequence due to the absconding of the second one.

当基本罪不成立时，第二段的&逃逸&是以交通肇事行为为基础的犯罪构成要件的内容，具有被独立评价的地位；第三段的&逃逸致人死亡&是以第二段&逃逸&为原因力的结果加重犯。

On the ground of China's primary state, the mode which combines the statutory and discretionary system and averts the disadvantages shall be adopted. In this mode, the statutory system shall mainly be used in judging competency of evidence, while the discretionary system in weight of proof and the two systems are as important as the other.

在我国，从现阶段的基本国情出发，我们应当在抛弃两者缺点的基础上，选择法定认证与自由认证相结合的认证模式，证据能力以法定认证为主，证明力以自由认证为主，两者不分主次轻重。

Then, this topic discuses the competence model theory and how to build.

第二部分论述了胜任力模型的基本理论和构建方法。

But in actual life, each stationmaster has had this kind of experience, in exchange join does not have a few days, the other side expunges join with respect to for no reason at all, make its already made the one-way connection of a few months for nothing oneself, gave many power for the other side, him website quality did not rise, still have even if some stationmaster scheming are heavy, make with Nofollow attribute its website join does not have any action, return some to be called with JS etc, the method that can use anyway is basic it is to be used completely, make join did not rise any action.

但是在现实生活中，各位站长都有过这种经历，在交换连接没有几天，对方就无缘无故把连接删掉，使其自已白白做了几个月的单向连接，为对方出了不少力，自己网站质量没提高，还有就是有的站长心机重重，用nofollow属性使其网站连接无任何作用，还有的用JS调用等等，反正能用的手段基本是全用到，使连接没有起到任何的作用。

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）。
