I f

One relatively simple fix, Mr. Zdziarski said, would be for Apple to modify future versions of the iPhone to require a user to enter a passcode before the phone will accept the sort of modified operating system that the F.B.I. wants Apple to create.

兹阿尔斯基表示，对于苹果公司来说，一种相对简单的补救方式就是，未来推出的iPhone版本做些改变，手机在接受苹果依照联邦调查局的意愿改动的操作系统前，用户要输入密码来确认。

What the hell are you doing? I f you don't think they watch us in here, you're wrong! Hey. I'd put that down if I were you.

你到底在做什么你以为他们没有监视我们你就错了嘿如果我是你我会把它放下

I f you can meet with Triumph and Disaster And treat those two imposters just the same;

假如你能&在遇到胜利和困难时态度同样平静；

I f he doesn't, you spend the night with me.

如果他没打，你就跟我过夜。

This paper introduces the development of I F research area, TRECs and what they had done on IF.

介绍了目前评估领域的发展情况，TREC会议及其在信息过滤领域做出的贡献。

The action stems from a federal court order issued on Tuesday requiring Apple to help the Federal Bureau of Investigation ( F.B.I) to unlock an iPhone used by one of the two attackers who killed 14 people in San Bernardino, California, in December.

去年12月，加利福尼亚州圣贝纳迪诺市两名袭击者杀死了14人。周二，联邦法院下令要求苹果公司协助联邦调查局的调查，解锁其中一名袭击者曾用过的iPhone手机，政府的行动正是源于这个法令。

As Apple and several security experts have argued, an order compelling Apple to write software that gives the F.B.I.access to the iPhone in question would establish an unsettling precedent.

就像苹果及几名安全专家所说的那样，下令强迫苹果公司编写软件，使得联邦调查局能够进入相关的iPhone，这会创下令人不安的先例。

In other words, even if the F.B.I. wins this case, in the long run, it loses.

换言之，即便联邦调查局赢了这场官司，从长远来看，他们还是会输。

Aim and Methods: By using two microelectrode voltage clamp technique, to observe the effects of adenosine ( Ad) on pacemaker current I f were examined in sheep cardiac Purkinje fibers.

目的和方法：用双微电极电压钳技术，观察腺苷（adenosine，Ad）对绵羊心室浦肯野纤维起搏离子流1f的影响。

Investment and financing ( I F) is the core of modern economy, there is a close relationship between I F and the development of urbanization.

投融资作为现代经济的核心，与城镇化发展之间存在着密切关系。

A design of measuring system for I/ F convertor

I/F变换器测试系统设计

If Apple is forced to write code that lets the F.B.I. get into the Phone 5c used by Syed Rizwan Farook, the male attacker in the San Bernardino attack, who would be responsible if some hacker got hold of that code and broke into its other devices?

如果苹果公司被迫编写代码让联邦调查局进入圣贝纳迪诺袭击者赛义德·里兹万·法鲁克用过的iPhone5c的话，如果某个黑客获取了这些代码、用来入侵其他设备，那谁来负责呢?

Cardiac pacemaking is controlled by an inward current called I f, which is activated by membrane hyperpolarization of pacemaker cells in the sinoatrial node.

心脏的起搏受控于一类存在于心脏窦房结被称作If的离子通道，该通道是被细胞膜的超极化所激活。

Urbanization development needs adequate funding, balanced relationship between urbanization I F supply and demand, and efficient management of urbanization I F. They are conductive to promote the further development of urbanization.

城镇化发展需要充足的资金保障，均衡的城镇化投融资供求关系、高效的城镇化投融资使用及管理有利于进一步推动城镇化的发展。
