查询词典 calculus of approximations

Results Successful lithotripsy was achieved in 78 cases ,two cases failed because movement of calculus to pelvis renalis in one and no access to calculus site by ureteroscope due to ureterostenosis at inferior segment in the other .

结果 1例因结石上移至肾盂，1例因输尿管下段狭窄使输尿管镜无法到达结石部位手术失败，其余78例均碎石成功，术后当天肾绞痛缓解，碎石手术成功率和术后肾绞痛缓解率均为97.5%。

In order to remove the grave interference in the mobile ambients calculus, the author presents a Robust Ambients calculus which can restrict the coactions.

动态环境演算在资源受限情况下会出现强干扰问题，为了解决这个问题，论文提出了一种可以限定反动作对象的抗干扰鲁棒环境演算。

A kind of interference, called direct access interference, is found in the calculus of Mobile Resources, which will cause more damage than the grave interference one finds in the calculus of Mobile Ambients,because in MR malicious environments or contexts can freely access the sensitive resources inside a process.

在移动资源演算中发现了一种干扰现象，称为直接访问干扰，该现象比移动灰箱演算中的墙干扰现象更具破坏力，因为在MR中恶意的环境或上下文可以不受限制地访问进程内部的敏感资源。

When the grave interference has been resolved in the mobile ambients calculus by the coactions, the insecurity factors in ambients calculus have been effectively removed through using the parameters of the coactions.

在依靠反动作解决动态环境演算中强干扰问题的同时，利用反动作的参数明确了该反动作的使用对象，有效地消除了动态环境演算中存在的不安全因素。

Calculus courses have often suffered from focusing too narrowly on symbol manipulation exercises; at worst, the truly useful, interesting, and important ideas of calculus can disappear in a welter of half-understood formal symbols.

微积分课程常常遭受重点过于狭窄的象征手法演习；在最坏的情况下，真正有用的，有趣，重要思想的结石可以消失在飞扬的半理解正式符号。

They test pre-calculus, and calculus, and most importantly, proof.

测试的内容包括微积分先修课程、微积分，还有最重要的论证。

在此基础上进行了三维盐丘地质模型的地震波传播数值模拟试算。

In this paper, on the base of paraxial approximations, we present a set of absorbing boundary conditions of 3D elastic wave equations and apply to the 3D elastic wave numerical modeling in isotropic medium.

本文基於傍轴近似法提出了计算三维弹性波方程的吸收边界条件公式，表示了各边界面、边棱和角点处波场所满足的单程波方程，并在三维弹性波数值模拟中进行了应用。

There are various techniques for constructing analytical approximations to the nonlinear differential equation.

早期研究非线性振动的理论分析方法多局限於弱非线性振动系统，碰到强非线性振动系统就显的无能为力。

Listen,point and check your answers.

听，指出并且检查你的答案。

Warming needle is one of effective treatment methods for knee arthralgia aggravated by cold,and it is simple,safety,so it should be developed in clinical acupuncture and moxibustion extensively.

但以本院科针灸门诊在2005年1月—2006年6月期间共收治膝痛患者100余例，经过临床的诊断后，其中施以温针治疗的48例，疗效显著，报道如下。1临床资料本组病例48
