不能使用的

Comparing with other renewable energies, geothermal energy is stored underground and independent ofweather. It can be used both for base load and peak power.

地热能储存于地下，不受气候条件的影响，既可作为基本负荷能，也可作为峰值负荷能使用。

This discourse mostly discuss that design and implement the management system on hosputal.the function which system can complete is:management the payfile、examine change、materia medica management、prior sclect、management be in hospital and so on.this system is main of different roles and execute different mission to design,these role seperate of common employee、material management person、finance accountant person、hospital management person,different roles dispensatory different mission and function.each role only can use the function which been distributive and can't operate other operation get out of line,so to achieve the aim of that each operation logic independence、dynemic link、highly compositive.all kinds of roles use the client is not same,limated correspond task modules to deal with operation.

本篇论文主要讨论了医院管理系统的设计及实现。系统主要完成的功能有：工资档案管理、门诊收费、药品管理、院长查询、住院处管理等；本系统是以企业中不用角色执行不同任务为主线进行设计的，这些角色分别为普通员工、物资管理人员、财务会计人员、医院管理人员，不用的角色所分配的任务和功能也各不相同。各角色只能使用被分配的功能而不能违规操作其他业务，以便达到各业务逻辑独立、有机联系、高度集成的目的，各类角色所使用的客户端不同，限定相应工作模块，进行业务处理。

The LAB series bonding agents (modificating of alcohol amine complexing with boron trifluoride),the hydantoin and triazine series bonding agent BA603 and the borate ester bonding agent BAG-5 can effectively raise the mechanical properties of the high-energy four groups HTPB propellant when complexing with MAPO,but they can not meet the require- ments of the engine use.

改性醇胺和三氟化硼的络合物LAB系列键合剂、海因三嗪类键合剂BA603与有机硼酸酯键合剂BAG-5在与MAPO复配用于高能丁羟四组元推进剂中，能有效提高推进剂力学性能，但都不能满足发动机使用要求。

But a big drawback, which may irk loyal Mac followers , is that the site is unable to accommodate

但它也有一个很大的缺陷，就是不能接纳使用Macin－tosh操作系统的用户：用户只能发送而不能预览或接收贺卡----这一点也许使Mac的忠实追随者感到恼怒。

In 1937, armed conflict between Japan and China commenced, thereby starting a series of historical world events that would keep my mother from retuning to China until 37 years later and after her parents has passed away without her ever seeing them again.

但是，后来她坚持说，因为了解到女生仍不允许使用密歇根大学学生会的会所，而她不愿意忍受二等学生待遇，才决定留在伯克利。1937年，日本发动侵华战争，触动了此后又发生了一系列的历史性国际事件，阻碍了使母亲回国，直在离开老家到37年后她方能回去中国时，那时她父母早已去世，她再也没能见上他们一面。

Force yourself to use your brain, The only way to gain, A lot of things are just a lie This world we love comes down in pain With hate and bloody games A question-mark up in the sky Look, you can't keep away And you can't hide Tomorrow, yesterday, today... Some people say, we'll do it better Some people say, everything's good Some people sing, let's come together But nobody has ever brought it through Maybe you and me...

强迫自己使用你的大脑，只有这样，才能增益，很多东西只是一个谎言这个世界上，我们爱归结为在痛与仇恨和血腥的游戏提问标示在天空你看，你不能远离你不能隐藏明天，昨天，今天……有人说，我们将做更好有些人说，一切都很好有些人会唱，让我们走到一起但没有人带着它通过也许你和我。。。

As for the pesticide-resistant species you have mentioned, we can try to reduce the amount of weed killer used, but the idea of abandoning weed killer is unreasonable. Total abandonment will not benefit current ecological balance.

至于您提到的抗除草剂品种依然需要除草剂，那是当然，毕竟现在只能降低除草剂的使用，不能杜绝除草剂的使用，而且完全杜绝了也不好，不符合生态平衡的要求。

In order to draw a photorealistic surface, Bidirectional Texture Functions, a 6D texture function which extends Bidirectional Reflectance Distribution Function to include the self-shadowing, self-occlusion and inter-reflection effects, has been mentioned frequently in recent years. Its main drawback is its massive data size. To solve this, Spatial Bidirectional Reflectance Function techniques compress BTFs into reflectance model parameters. However, SBRDF cannot producethe self-shadowing and self-occlusion effects in real-world surface geometry. This work is aimed to this drawback. I find how self-shadowing and self-occlusion affect the surface by additional physical-based analysis. And I rely on two physical phenomena to divide self-shadowing and self-occlusion into two independent effects. First, self-shadowing is view independent. Second, self-occlusion is independent of lighting direction changes. After these analyses, I use SBRDF and additional self-shadowing and self-occlusion I found to render a photorealistic surface as non-compressed BTFs doing.

为了把物体表面呈现的更真实，六维函数BTFs ( Bidirectional Texture Functions)目前已经被使用的相当频繁，但BTFs的资料量实在太大而没办法直接使用，为了解决资料庞大的问题，传统的SBRDF以逼近光反射模型参数，来达到资料压缩的效果，但是SBRDF对於表面的凹凸所产生的阴影及遮蔽，不能达到逼真的呈现，为了改善这个问题，我们选择从物理方面，找出资料中阴影和遮蔽等属於表面几何的资料并去除，使参数更正确，同时利用两个物理现象去区分阴影及遮蔽为两个互不干涉资料，第一是阴影不会因视角不同而改变，第二是遮蔽不因光线方向不同而改变，经过这些分析，我可以利用SBRDF加上附加的阴影及遮蔽两种独立的效应，来达到彷佛跟未压缩过的BTFs一样的真实绘图。

Without session keys and authenticators, Charon can protect its servers from false users, but it cannot protect its users from false servers.

没有会话密钥和验证器，Charon能够保护它的服务器不被错误的用户使用，但它不能防止它的用户使用错误的服务器。

There can be no static members of a local class. Local class members may not access the local variables defined in the enclosing function. They may use type names, static variables, or enumerators defined in the enclosing function.

局部类不能有静态成员，局部类成员不能访问外围函数中定义的局部变量，它们可以使用外围函数中定义的类型名、静态变量和枚举成员。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
