He has been linked to volleyball star Gabrielle Reece, English actress Minnie Driver, porn star Jenna Jameson, Goldie Hawn's 16 year old daughter Kate Hudson and several strippers.

他曾经和排球明星加布里埃尔·里斯(老虎伍兹曾经追过的明星)、英国女演员米妮，德里佛、三级片明星珍娜·詹姆逊、著名搞笑影后戈尔迪·霍恩十六岁的女儿凯特·哈德森和一些脱衣舞女发生过绯闻。

A method of measuring static magnetic parameters of magnetic materials utilizing fluxgate sensor and Helmholtz coils is proposed for the first time.

首次提出应用磁通门传感器和亥姆霍兹线圈测量静态磁参数的方法，这种方法具有很好的技术先进性。

In this paper,some instruments with different functions are combined,and by using the motion of charged particle s in the alternating magnetic field produced with Helmholtz coils,the existence of the induced electric field can be validated directly and easily.

针对磁场变化时激发产生的感生电场很难演示的问题，设计了演示感生电场存在的实验。该实验将不同功能的仪器组合起来使用，通过亥姆霍兹线圈的交变磁场对带电粒子的作用效果，直观说明感生电场的存在

This paper explores the application of the modern digitized technology to the teaching of the Electromagnetism. By the numerical calculation and digital simulation, the electromagnetic field of an uniformly charged ring, the non-linear vibration of charged particle in an uniformly charged ring and the uniform area of Helmholtz coils are discussed.

本文探讨现代数字技术在电磁学教学中的应用，通过数值计算和数字模拟，深入讨论了环形源电磁场的空间分布、带电粒子在带电圆环电场中的非线性振动以及亥姆霍兹线圈内的均匀磁场问题。

With the need, the researchers used are: permanent magnets,electromagnetic Helmholtz coils and solenoids as magnetic field devices.

由于实验的需要，研究人员常用的磁场发生装置有：永磁铁、电磁铁、亥姆霍兹线圈和螺线管。

This device, which is composed of oscillator, switching capacitor, second-order tracking system, digital switching system, power-amplifier circuit and Helmholtz coils , can produce rotating magnetic field whose frequency and strength can be adjusted continuously.

该装置由振荡器、开关电容、二阶跟踪系统、数字开关系统、功放电路及亥姆霍兹线圈组等部分组成，可以产生频率、强度连续可调的旋转磁场。

Proof of this has usually rested on demonstrating that individuals whose ability to perceive the magnetic field is disrupted (by having small magnets attached to them or by being kept in cages surrounded by Helmholtz coils) cannot orient correctly, whereas control animals can.

要证明这一点，通常要用实例显示：如果动物个体的感知磁场能力受到破坏(通过在它身上系上小块磁条，或者把它关在由赫姆霍尔茨线圈包围的笼子里)，那么它就不能确定正确的方向，而对比动物却能够确定正确方向。

Permanent magnet can provide for a maximum intensity of the magnetic field around Tesla, Helmholtz coils and solenoids can provide alternating magnetic field or relatively uniform magnetic field, and solenoids can also be used to provide strength for the solenoid around 10 Tesla.

其中永磁铁能够提供强度最大为1特斯拉左右的静磁场，亥姆霍兹线圈和螺线管可提供交变磁场或相对均匀的磁场，也可用螺线管提供强度为10特斯拉左右的超强静磁场，电磁铁则可产生强度为几百毫特斯拉或特斯拉级的静磁场。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.

气候直方图是将所收集的降水量测定值，分为几个相等的区间作为横轴，并将各区间内所测定值依所出现的次数累积而成的面积，用柱子排起来的图形，也叫做柱状图。
