【正文】 有高溫退磁、抗振性較差等不足；德國、英國等大力開發(fā)開關磁阻電機，優(yōu)點是結構簡單、可靠．成本較低．缺點是質量較大，易于產生噪聲。目前我國也研制成了稀土永磁無刷直流電機和開關磁阻電機 ?電動機的使用尚無定論，有待今后在使用中考驗。 3．混合動力汽車 由于受到蓄電池性能的嚴重制約．使純蓄電池型電動汽車 的產業(yè)化進程舉步維艱，于是混合動力汽車成了內燃機汽車和電動汽車之間的過渡產品，既充分發(fā)揮了現有內燃機技術優(yōu)勢，又盡可能發(fā)揮電機驅動無污染的優(yōu)勢?；旌蟿恿ζ噷F有內燃機與一定的儲能元器件通過先進控制系統(tǒng)相結合，可以大幅度降低油耗，減少污染物排放，同時技術成熟、價格便宜。 4．燃料電池汽車 燃料電池汽車在成本和整體性能上，特別是行程和補充燃料時間上明顯優(yōu)于其他電池的電動汽車，開且燃科電池所用的燃科 (甲醇、汽油、柴油、天然氣等 )來源廣泛，又可再生，并可實現無污染、零排放等環(huán)保標準。所以燃料電池轎車已 成為世界各大汽車公司 21 世紀初激烈競爭的焦點。日本《東洋經濟》報道 .“當代技術革命將徹底改變 2l 世紀汽車業(yè)的面貌，這一改變就是在近幾年出現的燃料電池車 ”。 目前，在電動汽車的商業(yè)化運作上，無論從產品技術還是從市場開發(fā)方面．都還面 I 臨許多亟待解決的問題，這就需要政府的大力支持。比如，加快制定相關技術標準，出臺對節(jié)能、 環(huán)保汽車的稅費減免和補貼措施，在基礎設施建設上提供便利條件等。 參考文獻 [1]祝占元 .電動汽車 [M]河南 :黃河水利出版社 ,2021.

You may need to make a claim to an employment tribunal if: you don39。t agree with the disciplinary action your employer has taken against you your employer dismisses you and you think that you have been dismissed unfairly.

Most people find making a claim to an employment tribunal challenging. If you are thinking about making a claim to an employment tribunal, you should get help straight away from one of the anisations listed under Further help. ation about dismissal and unfair dismissal, see Dismissal. You can make a claim to an employment tribunal, even if you haven39。t appealed against the disciplinary action your employer has taken against you. However, if you win your case, the tribunal may reduce any pensation awarded to you as a result of your failure to appeal. Remember that in most cases you must make an application to an employment tribunal within three months of the date when the event you are plaining about happened. If your application is received after this time limit, the tribunal will not usually accept i. If you are worried about how the time limits apply to you If you are being represented by a solicitor at the tribunal, they may ask you to sign an agreement where you pay their fee out of your pensation if you win the case. This is known as a damagesbased agreement. In England and Wales, your solicitor can39。t charge you more than 35% of your pensation if you win the case. you39。re clear about the terms of the agreement. It might be best to get advice from an experienced adviser, for example, at a Citizens Advice Bureau. To find your nearest CAB, including those that give advice by , click on nearest CAB.

I am going to be at the match tomorrow and I have asked to meet Ya ya Toure, he told BBC Sport. For me it39。s about how he felt and I would like to speak to him first to find out what his experience was. Uefa has opened disciplinary proceedings against CSKA for the racist behaviour of their fans during City39。s 21 win. Michel Platini, president of European football39。s governing body, has also ordered an immediate investigation into the referee39。s actions. CSKA said they were surprised and disappointed by Toure39。s plaint. In a statement the Russian side added: We found no racist insults from fans of CSKA.
