查询词典 indefinite total variation

Sediments of this system were sequentially extracted in natural granularity. The result showed that there was a good linear relationship between organic matter and org / bact P contents in sediments. This organic matter in sediments was the source of org / bact P. The total phosphorus in sediments dominated the content of total dissolved phosphorus and phosphate in interstitial water. In addition, there were good relatiohships between total phosphorus in sediment and the total dissolved phosphorus in interstitial water, and between total phosphorus in sediment and phosphate in interstitial water. FeP and AlP in sediments were correlative with Eh and phosphate in interstitial water, respectively. This showed that the FeP and AlP contents were affected by Eh in interstitial water and the total content of FeP and AlP dominated the content of phosphate in interstitial water.

对沉积物—间隙水中磷形态的连续提取分析发现，自然粒度下，沉积物中有机质含量与沉积物中有机/细菌聚合磷存在很好的线性相关性，说明沉积物中有机质是有机/细菌聚合磷的源；沉积物中总磷决定间隙水中总溶解性磷和溶解性磷酸盐的含量，并且总磷与间隙水中总溶解性磷和溶解性磷酸盐存在很好的相关性；沉积物中FeP和AlP分别与间隙水中的Eh和溶解性磷酸盐存在相关性，说明Eh的大小严重影响FeP和AlP的含量，但是FeP和AlP含量之和又主导着间隙水中溶解性磷酸盐的含量。

For example, we analyzed why this construction came into being in Chinese, the essential reason is that t here is not the distinction of verb's definite form and indefinite form,(改为: there is no distinction between verb's definite form and indefinite form)and, parataxis in sentence making.

如我们考察了一个汉语中连动结构产生的原因，汉语中连动结构产生的根本原因有两条：汉语动词没有限定形式和非限定形式之分，以及汉语中的意合组句的方式。

Therefore, it is not every Newton indefinite integral that can carry on Riemann integral, and not every Riemann integral has Newton Indefinite integral.

牛顿所积分的函数都是连续的，可分为牛顿不定积分和牛顿定积分，而黎曼所积分的函数又是有界的。

Based on the quality of linear operation about indefinite integral, the article puts forward an indefinite integral principle of making linear combination and reducing power of integrand.

从不定积分的线性运算性质出发，给出了计算不定积分的被积函数线性组合化、降幂的积分原则，并结合实例分析了这一原则在不定积分计算中的指导作用

If nevertheless we would attempt to define the notion "indefinite," then that's a paradox because if we succeed, then it is defined, which contradicts its meaning – its indefiniteness – and the word "indefinite" means that it cannot be defined.

但是如果我们试图界定概念"无限期"，那么，这样的悖论，因为如果我们成功，那就定义这与它的意义--其不确定性和"无限期"的意思，所以无法确定。

This article has sorted out the data of indefinite integral concept in common use, and has analyzed the features of three methods of indefinite integral in common use: the first substitution method of integration, the second substitution method of integration, and integration by parts.

因为，(x2)′=2x，(x2+1)′=2x，(x2+2)′=2x，(x2+c)′=2x所以x2，x2+1，x2+2，x2+c均为2x的原函数。由此得出：一个函数若有原函数存在则有无数个原函数存在，且任意两个原函数之间相差一个常数。

Using the soliton theory we obtain a method to contract isometric immersions from indefinite space forms into indefinite space forms with the same index.

我们利用孤立子理论得到了构造有相同指标的不定度量空间型到不定度量空间型的等距浸入的方法。

In judging of the radix of an indefinite set, an one-one mapping between it and a known radix of indefinite set must be found out.

由于在判断一个无限集合的基数时，必须找出它与另一个已知基数的无限集合之间的一个双射函数。

This paper mainly discusses a kind of indefinite stochastic linear quadratic optimal control problem with incomplete data, which can be described as: Minimize subject to Here Q, F are indefinite symmetric matrices,R is a positive semidefinite symmetric matrix.

本文主要讨论的是一类部分信息下的不定随机LQ问题，其形式如下：这里Q，F为不定对称矩阵，R为非负对称矩阵。

TAUNTON, Mass.- General Dynamics C4 Systems announced a ＄78.3 million initial order from the U.S. Army as part of an indefinite delivery/indefinite quantity contract worth up to ＄1.4 billion for Warfighter Information Network-Tactical Increment One, which provides U.S.
